A 27-year-old patient carrying a transvenous ICD developed infective endocarditis more than 1 year after surgery. Staphylococcus aureus was isolated from blood cultures. A transesophageal echocardiogram revealed a mobile vegetation on a thrombus attached to the ICD lead in the right atrium. The ICD lead was removed by right anterolateral thoracotomy. This raises the issue of the risk of thrombus formation in patients with intravenous ICD leads and the associated susceptibility to infective endocarditis.

Between March 1995 and June 1997, 128 leads were extracted from the hearts of 28 women and 50 men, 69 +/- 15 years of age (mean +/- SD, range 22-92 years). The indications for the procedure were: Accufix leads in 18 patients (14%), dysfunction or incompatibility with ICD in 16 (12%), endocarditis on the lead in 41 (32%), pulse generator pocket infection in 28 (22%), and pulse generator and/or lead erosion in 25 patients (19%). The extraction was performed with a snare (lasso), via a femoral vein as a first approach in 116 leads, and as an alternate approach, after extraction from the original site of implantation had failed, in 12 leads. The leads had been implanted for 62 +/- 48 months (range 1-205 months). A Cook sheath was used in 7, and a femoral approach traction in 20 instances. Of the 128 leads, 122 (95%) were completely extracted, and 2 (2%) were partially extracted (the distal electrode remaining attached to the myocardium), and 4 (3%) could not be removed. Four complications occurred: 2 tears of the tricuspid valve without clinical consequences, one separation of the lead's distal electrode which migrated into the hypogastric vein, and one hemorrhage at the femoral puncture site. There was no death or serious complication caused by lead extraction in this series.

Eight patients, 4 males and 4 females ranging in age from 10 to 54 years (mean 27 +/- 13 years) underwent the Ross operation using a cryopreserved pulmonary homograft harvested by and cryopreserved in our institutional "Tissue Bank". Seven patients had a congenital bicuspid aortic valve and 3 patients had had healed infective endocarditis of the aortic valve. Four young female patients wanted to have a baby after operation. The Ross procedure was carried out utilizing aortic root replacement techniques in all patients. All patients survived and are currently in NYHA class 1, but 2 cardiac events occurred in 2 patients during the mean follow-up term of 29 +/- 19 months. The one was the anastomic stenosis between the homograft and distal pulmonary artery treated by balloon dilatation and the other was ventricular tachycardia eventually managed by the insertion of an ICD. Pulmonary autograft valve regurgitation is present in 3 patients, but it is not progressive up to the present time. Pulmonary homograft valves function well in all patients. The Ross operation for adolescents and young adults should become more popular along with more easy availability of homograft valves based upon the establishment of the "Homograft Valve Bank" system in Japan.

Extraction of pacemaker leads represents the optimal therapy in patients with endocarditis involving the pacemaker leads. The percutaneous approach is becoming popular. However, complications of percutaneous extraction are not rare and incomplete removal of the vegetations with embolization in the pulmonary arteries has been described. This case report describes for the first time a case of incomplete removal of the fibrous sheath covering the lead, with residual tissue floating in the right atrium after pacemaker/ICD extraction. ICE monitoring was essential for early detection and correct diagnosis of this complication.

The risk of infective endocarditis on pacemaker or ICD is not negligible and has increased in recent years. Several host-related, procedure-related, or device-related risk factors have been recognized. Owing to its potential severity, the possibility of infective endocarditis should be envisaged in patients with repeated pulmonary infections or documented bacteremia and transesophageal echocardiography should then be used. The most common germs causing pacemaker endocarditis are staphylococci. Treatment requires prolonged antibiotic therapy and retrieval of the pacemaker and leads.

Implantation of electrophysiological cardiac devices such as pacemakers and implantable cardioverter defibrillators has become a widely available and routine procedure in cardiovascular medicine. One of the most feared complications of device implementation is infection. Infection rates for these devices are reported to vary between 0.7% and 7.0%. Cardiac thromboembolic event is a recognized complication of permanent cardiac rhythm devices with an incidence of 0.6%-3.5%, unrelated to lead size or number. These complications are associated with high morbidity and mortality rates. In this case report, right atrial mass, right atrial abscess, perforation of tricuspid septal leaflet, and pulmonary embolism secondary to ICD lead endocarditis is presented.

Little is known about the magnitude of the association between infective endocarditis and cancer, and about the natural history of cancer patients with concomitant diagnosis of infective endocarditis. We used the SEER-Medicare linked database to identify individuals aged 65 years or more diagnosed with colorectal, lung, breast, or prostate cancer, and without any cancer diagnosis (5% random Medicare sample from SEER areas) between 1992 and 2009. We identified infective endocarditis from the ICD-9 diagnosis of each admission recorded in the Medpar file and its incidence rate 90 days around cancer diagnosis. We also estimated the overall survival and CRC-specific survival after a concomitant diagnosis of infective endocarditis. The peri-diagnostic incidence of infective endocarditis was 19.8 cases per 100,000 person-months for CRC, 5.7 cases per 100,000 person-months for lung cancer, 1.9 cases per 100,000 person-months for breast cancer, 4.1 cases per 100,000 person-months for prostate cancer and 2.4 cases per 100,000 person-months for individuals without cancer. Two-year overall survival was 46.4% (95% CI 39.5, 54.5%) for stage I-III CRC patients with concomitant endocarditis and 73.1% (95 % CI 72.9, 73.3%) for those without it. In this elderly population, the incidence of infective endocarditis around CRC diagnosis was substantially higher than around the diagnosis of lung, breast and prostate cancers. A concomitant diagnosis of infective endocarditis in patients with CRC diagnosis is associated with shorter survival.

Abiotrophia species are relatively slow growing pathogens, which may be present as commensal flora. However, invasive infections are frequently reported, like endocarditis, septic arthritis, osteomyelitis, and many other types of infection. In this case report we describe a 65-year-old male patient with an intracardiac device- (ICD-) lead infection caused by Abiotrophia defectiva. Diagnosis was confirmed by (18)F-FDG-PET scanning. This is remarkable, since Abiotrophia defectiva is a slow growing pathogen causing low-grade infections. This case demonstrates that although infection of ICD-leads cannot be excluded in case of (18)F-FDG-PET-negative findings, positive findings are highly suggestive for infection.

To study the role of carotid stenosis (CS) and cerebrovascular disease as independent risk factors for perioperative stroke following surgical aortic valve replacement (SAVR). The National Inpatient Sample (NIS) database was used for our study. All patients who underwent SAVR from 1999 to 2011 were identified using ICD-9 codes. Univariate and multivariate analysis of baseline characteristics, Elixhauser comorbidities and other covariates were examined to identify independent predictors of perioperative strokes following SAVR. Data on 50,979 patients who underwent SAVR from 1999 to 2011 was obtained. The mean age of the study cohort was 60.5. The study patients were predominantly Caucasian (79.3%) and males (60.01%). The incidence of perioperative stroke was 2.48%. CS (OR 1.8, 95%CI 1.1-2.8, p=0.009) and cerebral arterial occlusion (OR 3.4, 95% CI 1.3-8.9) significantly increased perioperative stroke risk following SAVR. Infective endocarditis (OR 4.6, 95%CI 3.8-5.6, p=0.00) and neurological disorders (OR 4.8, 95% CI 4-5.8, p=0.00) appeared to be the strongest risk factors for strokes. Other risk factors found to be significant predictors of perioperative strokes (p<0.05) were - age, higher VWR scores, CS, cerebral arterial occlusion, infective endocarditis, DM, HTN, renal failure, neurological disorders, coagulopathy and hypothyroidsm. In conclusion, perioperative stroke risk has remained more or less constant despite advancements in surgical techniques with risk having gone up in patients <65years of age. CS and cerebral arterial occlusion significantly increase stroke risk following SAVR. Improved patient selection with pre-operative risk stratification and institution of preventive strategies are necessary to improve operative outcomes following SAVR.

A 64-year-old African American woman presented for defibrillator threshold testing (DFTs) after a recent hospitalization for ventricular fibrillation terminated by her ICD. She had a known history of non-ischemic cardiomyopathy, atrial fibrillation, rheumatic mitral valve disease s/p mitral valve replacement and a redo after subsequent endocarditis. In preparation for the DFTs, the patient underwent a transesophageal echocardiogram (TEE) to rule our left atrial (LA) or LA appendage thrombus. Patient was found to have a surgically closed appendage. Within the body of the closed appendage, a mobile thrombus was seen with clot free areas surrounding the thrombus. Doppler and contrast studies confirmed that there was no communication between the LA and the appendage. The patient underwent DFTs without complication and a follow-up TEE confirmed the presence of the clot in the non-communicating LA appendage.
