A 56-year-old male with two mycotic aneurysms associated with infective endocarditis was treated by endovascular surgery before mitral valve replacement. Angiography revealed a ruptured proximal aneurysm and an unruptured distal aneurysm on the right middle cerebral artery. The ruptured aneurysm was successfully treated with an interlocking detachable coil, and patency of the parent artery was preserved. The unruptured distal aneurysm disappeared as a result of antibiotic therapy. Endovascular surgery of the mycotic aneurysm is less invasive and more effective than craniotomy under general anesthesia for patients with infective endocarditis.

Surgical closure of multiple muscular ventricular septal defects (MVSDs) is associated with mortality and morbidity; therefore, both surgeons and cardiologists welcome a nonsurgical safe approach. We report our initial results of catheter closure of MVSD using the new Amplatzer muscular VSD occluder delivered via the venous or arterial routes. Eight patients with MVSD underwent closure of their VSDs using the Amplatzer VSD occluder under general endotracheal anesthesia. The mean +/- SD of age was 5.4 +/- 3.1 years (2-10 years) and mean weight was 18.4 +/- 6.5 kg (11.5-29 kg). All patients had left ventricular volume overload with mean Qp/Qs ratio of 1.7 +/- 0.6 (1.4-3). The location of the VSD was mid muscular in four, anterior in two, apical in one, and posterior in one. The systolic pulmonary artery pressure ranged from 25 to 85 mm Hg (mean, 39.9 +/- 18.8 mm Hg). The device was implanted successfully in all eight patients. In five patients (four mid muscular and one apical), the deployment of the device was anterograde from the right internal jugular vein and in three patients (two anterior and one posterior VSD), the initial attempt at anterograde deployment was unsuccessful due to kinking in the delivery sheath; therefore, retrograde deployment was attempted successfully. The size of the device used ranged from 6 to 14 mm (the size of the connecting waist). In patients with elevated pulmonary artery pressure, repeat measurements immediately after closure revealed normalization in all. There was immediate complete closure of the defect in two patients and six patients had trivial residual shunt (foaming through the device), which disappeared completely within 24 hr in five and at 6-month follow-up in the sixth patient. The mean fluoroscopy time was 37.1 +/- 13 min (11.7-55 min). Complications encountered included transient junctional rhythm in one patient. No blood transfusion was required. On follow-up evaluation, there has been no episode of endocarditis, thromboembolism, hemolysis, or wire disruption. we conclude that the Amplatzer MVSD occluder is a safe and effective device for closure of MVSDs up to 12 mm in diameter. Further clinical trials with this device are underway. Cathet. Cardiovasc. Intervent. 49:167-172, 2000.

In this review, we describe the experience from 13 European centres using the CardioSEAL and Starflex double umbrella devices to close interatrial communications within the oval fossa (so-called 'secundum' defects). Between October 1996 and April 1999, the procedure was attempted in 334 patients with a mean age of 12 years and a mean weight of 44kg. The mean measured stretched diameter of the defect was 15 mm. In the overall group, the defect was solitary in 245 patients (73%), multiple in 21 (6%), associated with an aneurysm of the flap valve in 15 (5 %), was represented by patency of the oval foramen in 44 (13%), and was a fenestration in a Fontan repair in 9 (3%). In all patients, the devices were inserted under general anesthesia, using fluoroscopic and transesophageal echocardiographic control. Implantation was achieved in 325 (97,3%). The device embolized within either a few minutes or a few hours in 13 patients (4%). Of these, uncomplicated surgical repair was undertaken in 10, while the device was retrieved in 3 using catheters and a second device was successfully implanted. Residual shunting was detected immediately after the procedure in 41% of the patients, with the incidence decreasing to 31% at discharge, 24% at 1 month, 21% at 6 months, and 20.5% at one year. During the period of follow-up, elective surgical repair became necessary in two patients, due to malposition of the device in one, and late embolization in the other. Fractures of arms were seen in 6.1 %, most commonly with the largest devices. All those with fractured arms of the device were asymptomatic, and no clinical complications related to the fractures were observed. There were no arrhythmias, endocarditis, valvar distortion, thromboembolic events, or other complications. After one year of follow-up, clinical success, defined as complete closure of the defect or presence of only a trivial leak, had been obtained in 92.5% of the patients. We conclude, therefore, that these devices produce excellent results when used to close defects of small to moderate size. Results are less than optimal, or else complications ensure, when attempts are made to close very large defects.

Cigarette smoking, hypertension, hypercholesterolemia, and periodontal disease have been established as major risk factors for cardiovascular disease. Dentists and physicians should work aggressively to educate periodontitis patients about this relationship in an effort to improve the quality of health and contribute to their long-term survival. Blood pressure should be checked at the initial dental visit and at each subsequent visit in patients whose blood pressure is found to be high and/or has a history of hypertension. Dental and medical assistants should receive in-service training to assure competency in measuring blood pressures. All staff should be certified in basic cardiopulmonary resuscitation. Emergency protocol procedures should be in writing and rehearsed regularly. Patients should take their blood pressure medication as usual on the day of the dental procedure. It is helpful for the patients to bring all medications to the office for review at the time of the dental procedure. Good communication should be established between the dentist and physician to maximize good dental and physical health. Because the patient with periodontal disease is at an increased risk for cardiovascular disease, a standardized form should be developed for the convenient exchange of vital information, including but not limited to: blood pressure, medications, allergies, medical conditions and pertinent highlights of dental procedures. Minimize stress in patients with coronary artery disease. This includes providing solid local anesthesia, avoidance of intravascular medication injections, and encouraging relaxation techniques. Antibiotic prophylaxis is indicated in patients with valvular heart disease but does not guarantee the prevention of endocarditis. These patients should be alerted to monitor any symptoms such as fever, chills or shortness of breath. It has also been documented that toothbrushing, flossing and home plaque removers can cause transient bacteremia in periodontal patients. Epinephrine use should be avoided or utilized cautiously in patients with pacemakers or automatic defibrillator devices because of the possibility of refractory arrhythmia. Consultation with patient's cardiologist is advised. Anticoagulation with coumadin is not a contraindication to dental procedures. The prothrombin time or international normalized ratio laboratory values should be checked on the day of the procedure to assure that it is in an acceptable range. Aspirin therapy is not a problem unless the patient is on very high doses for severe arthritis. Continuing medical and dental education credits should emphasize cross-training in both areas to insure comprehensive treatment of the patient with periodontal disease. Smoking cessation, regular exercise, a low-fat diet and good dental hygiene contribute to a healthy cardiovascular system. Patients should understand as best we know the relationship between periodontal and cardiovascular disease to afford them an opportunity to improve their overall dental and physical health.

We report our clinical experience with the newly developed Amplatzer device in transcatheter closure of nine atrial septal defects (ASDs), one ventricular septal defect (VSD), and one patent arterial duct (PDA). Eleven patients with ASD (age range 2.5-18 years) selected according to the location and size of the defect by transesophageal echocardiography (TEE), a five-year-old patient with muscular VSD and a one-year-old patient with PDA were considered for transcatheter closure with Amplatzer devices. All procedures were performed under general anesthesia with fluoroscopic and TEE guidance, following a routine hemodynamic evaluation in the catheter laboratory. The optimal device size was selected after the balloon sizing of the ASDs. The sizes of the VSD and PDA were measured on TEE and angiography. The patients were discharged at 24 hours, after an evaluation with x-ray, electrocardiogram (ECG), and echocardiography; they were on 3-5 mg/kg/day aspirin and infective endocarditis prophylaxis for six months after the procedure. They were reassessed at six to eight weeks and Holter monitoring was done in addition. Devices were used for nine ASD patients, and for the VSD and the PDA patients. Mean ASD size was 14.3 +/- 5.3 mm at TEE and 18.3 +/- 4.3 mm at balloon sizing (p=0.02). The mean size of the device was 18.7 +/- 4.2 mm. The procedure time and the fluoroscopy time were 46.1 +/- 12.3 and 12.9 +/- 1.6 minutes, respectively. Immediately after the procedure, four patients (44%) had trivial shunts (TS). TS remained in only two during discharge, and no shunt was observed at second evaluation. The devices were similarly applied to VSD (12-7 mm) and PDA (8-6 mm) patients. Both cases had TS immediately, which disappeared at 24 hours. None of the patients had major complications. Junctional rhythm developed in one patient, and another patient had frequent supraventricular extrasystoles. Amplatzer is an effective and safe device for transcatheter closure of ASD, VSD, or PDA, especially in pediatric patients.

The paper presents the most recent recommendations for the treatment and prevention of infective endocarditis (IE). The treatment of IE is complex and requires close collaboration among specialists in infectious diseases, cardiology, cardiac surgery and microbiology. The mainstay of medical treatment is antibiotic therapy. Theoretical considerations regarding vegetations and antibiotics have practical consequences on the route and modalities of administration of antibiotics and on the techniques used to monitor treatment. The choice of antibiotics depends on the microorganism (streptococci, enterococci, staphylococci, HACEK group [Haemophilus sp., Actinobacillus sp., Cardiobacterium sp., Eikenella sp. and Kingella sp.], Coxiella, Brucella, Legionella, Bartonella, fungi) and on whether IE occurs on native or prosthetic valves. Treatment of IE with negative blood cultures is particularly difficult. Cardiac surgery is often needed during the bacteriologically active period (in ~50% of patients). The decision to intervene and the optimal timing of the intervention requires careful consideration of multiple potential risks: the haemodynamic risk, the infectious risk, the risk due to cardiac lesions, the risk due to extracardiac complications and the risk due to the location of infective endocarditis. Even though the efficacy of antibiotic prophylaxis of IE is not completely proven, it is recommended for selected patients who undergo an at-risk procedure. Lists of cardiac conditions and of medical procedures at risk are presented; specific antibiotic prophylactic regimens for dental and upper respiratory tract procedures in out-patients, procedures under general anaesthesia and urological and GI procedures are outlined.

In our hospital, surgical antibioprophylaxis (ATBP) was too often administered too late, thus raising the infectious risk. Antibiotic stocks of the anaesthesia department were also systematically used, instead of nominal prescriptions of these drugs. The pharmacy could neither charge antibiotics to each surgical department nor quantify and differentiate ATBP from curative antibiotic therapy. The pharmacy and anaesthesia departments therefore set out to standardize surgical ATBP, in order to adapt this treatment to each surgical indication, and particularly in the case of allergy to beta-lactamase antibiotics (second line treatment kits). Consequently, prescription forms were developed and supplied to each surgery department, as well as ATBP kits. The kits were prepared and distributed by the pharmacy, and comprised boxes containing antibiotics in sufficient quantities to respect the protocols approved by the French Society of Anaesthesia and Resuscitation (SFAR). A protocol describing prescriptions, dispensation and administration has been presented to physicians and nurses. Fifteen surgical departments were included in our study and 30 different kits were prepared. From 1998 to 2001, 5586 surgical operations required administration of a kit (second line treatment kits in 5% of cases): 1848 (33%) in visceral surgery; 764 (13.8%) in urology; 802 (14%) in orthopaedics; 13 (0.2%) in vascular and thoracic surgery; 1236 (22%) in ear-nose-throat (ENT), periodontics and ophtalmology, and 923 (17%) in gynaecology and obstetrics. 93% of filled prescriptions forms were spontaneously returned to the pharmacy, the others were obtained during the renewal of kit stocks. The cost (over 4 years) of ATBP was quantified: 157,871 F for the 15 departments included, 26,123 F in visceral surgery, 13,520 F in urology, 73,741 F in orthopaedics, 569 F in vascular surgery, 39,720 F in ENT/ophthalmology/periodontics and 4,198 F in gynaecology and obstetrics. According to the Altemeier classification, 2226 class I, 3151 class II, and 209 class III surgical operations were performed. Since the kits have been brought into use, the committee for the protection against nosocomial infections (CLIN) has observed a reduction in the incidence of post-operative infections, according to the Altemeier classification: from 1.6% to 0.5% in class I, from 6.5% to 4.3% in class II, and from 11% to 8.5% in class III. The difference was statistically significant only for classes I (p < 0.01) and II (p < 0.001), and unchanged for class III (p = 0.3). No analysis was carried out for class IV (curative treatments). Both nurses and physicians have greatly appreciated the implementation of this organization. The advantage in terms of post-operative infections, administration exhaustiveness and stock management is obvious. The prescribed kits were systematically appropriate for the surgical interventions. In orthopaedics, cefamandole was used over 24 h (188 kits) in ligament plasty and osteotomy, or for 48 h (499 kits) in prosthetic surgery; 24 amoxicillin/clavulanic acid (first line) and 9 clindamycin/gentamicin (second line) single dose kits have been prescribed in traumatic indications. In ophthalmology, kits were only prescribed in endophtalmitis (24 ofloxacin/fosfomycin single amount kits), implant replacement or cornea graft (1076 ofloxacin 24 h kits) and cataract surgery in diabetic patients (12 ofloxacin single amount kits). In ENT and periodontics, 124 surgical operations required cefazolin single dose kits. In vascular surgery, 5 pefloxacin/gentamicin 48 h kits and 1 amoxicillin/clavulanic acid 48 h kit were used in contaminated limb amputation, 1 cefamandole 48 h kit in class I surgery and 1 vancomycin 24 h kit (betalactamase antibiotic allergy); in thoracic surgery, 1 cefamandole 24 h kit was used for a thoracic wound. In visceral surgery, 9 different kits have been used, depending on the opening (class II) or not (class I) of the digestive tract. 797 cefazolin (first line) and 68 clindamycin/gentamicin (second line) single dose kits were used in class I surgery, and 689 amoxicillin/clavulanic acid single dose (SD) kits in class II surgery. Specific protocols consisted of 18 ceftriaxone/metronidazole and 48 metronidazole/gentamicin SD kits in oesophagus surgery, 11 ceftriaxone and 17 gentamicin SD kits in biliary endoscopy, 137 metronidazole SD kits in proctology and 34 amoxicillin/gentamicin 6 h kits for prevention of endocarditis. In urology, 133 cefotaxime and 20 pefloxacin/gentamicin SD kits were precribed in renal lithiasis, 102 amoxicillin/clavulanic acid SD kits in cystectomy, 27 amoxicillin/gentamicin 6 h kits in endocarditis prevention and 58 cefamandole SD kits in all other indications. In gynaecology and obstetrics, 534 cefazoline and 19 clindamycin/gentamicin (second line) SD kits were used, and 370 doxycyclin SD kits were prescribed in pregnancy termination. Some departments (orthopaedics and visceral surgery) adapted the protocols to their needs, specifically with regard to treatment duration. However, these situations were quickly corrected. A constant follow-up and update of this system, associated with routine audits, should allow the maintenance and possibly the improvement of these results, hence shortening treatment duration.

Patients with cyanotic heart disease may have an acceptable quality of life but are exposed to several complications: polycythaemia, often beneficial but with its risks: hyperviscosity, hyperuricaemia, thrombocytopaenia, blood clotting abnormalities; and the other complications of right-to-left shunt: cerebral abscess, cerebral embolism, endocarditis. The hypoxia may be improved by interventional catheterisation or palliative surgery. The Eisenmenger syndrome is life-threatening in pregnancy or during general anaesthesia. These patients are at risk and sometimes have iatrogenic complications, so usual cardiological treatment may be dangerous: diuretics, ACE inhibitors, oral anticoagulants, antiarrhythmics.

We present a case of septicaemia, pneumonia and meningitis due to Streptococcus bovis type-II in a patient who had undergone a total hip prosthesis under general anaesthesia three weeks earlier. This organism is an uncommon human pathogen that sometimes causes bacteraemia and endocarditis and is usually connected with colon pathology and dental procedures. In the reported case, there were no risk factors for S. bovis infection except for the hip operation. S. bovis type II sensitive to penicillin was isolated from all blood and pleural fluid cultures. The patient recovered and was discharged from hospital two weeks after presentation.

Streptococcus salivarius is a usual commensal of skin, gastrointestinal tract, genitourinary tract, oral cavity and paranasal sinuses. Although it is usually considered to have low virulence, S. salivarius may cause life-threatening infections, particularly endocarditis. On the other hand, bacterial meningitis after spinal anesthesia is very rare, there being some reported cases caused by S. salivarius, S. mitis, Staphylococcus aureus and Enterococcus faecalis. We report a 57 year old man who developed meningitis symptoms within 10 h of an uncomplicated inguinal herniorrhaphy performed during spinal anesthesia. Cerebrospinal cultures grew S. salivarius sensitive to penicillin. The patient was successfully treated with penicillin G and left the hospital without sequelae. In the literature, bacterial meningitis due to S. salivarius is rarely reported. Of the 28 cases, 18 occurred after lumbar puncture for diagnostic or for spinal anesthesia, 5 occurred following a bacteriemia for upper gastrointestinal endoscopy or intestinal neoplasia, and the other 5 in patients who had dural defects. We discuss the possible etiological causes of the meningitis due to S. salivarius cases reports. The early recognition of this entity and the aseptic precautions likely to reduce the incidence of infectious complications after lumbar puncture are stressed.
