Among 21 consecutive patients with significant mitral regurgitation due to ruptured chordae tendineae operated by an author (K.M.) between March, 1980 and August, 1990, the 18 patients who underwent mitral valve repair were studied to assess the repaired valve function and late results of the repair. The chordal rupture was due to idiopathic degenerative disease in 14 patients, infective endocarditis in three and trauma in one. Patients' ages ranged from 35 to 70 years (mean age 52). Nine patients were in New York Heart Association class II and the remaining nine in class III. In three patients with ruptured chordae of the anterior mitral leaflet, reconstruction of the chordae with xenograft pericardium was performed in two patients and partial closure of a commissure in one. In 15 patients with ruptured chordae of the posterior leaflet, Kay's repair was performed in 13 patients and leaflet resection technique in two. In addition to the chordal and leaflet repairs, Kay's mitral annuloplasty was performed in all. There was no hospital death and all patients showed significant hemodynamic improvement (systolic pulmonary arterial pressure from 43 +/- 20 mmHg preoperatively to 24 +/- 4 mmHg postoperatively, and pulmonary arterial wedge pressure from 17 +/- 10 mmHg to 6 +/- 3 mmHg, p less than 0.001 respectively). The repaired valves showed mild pressure gradient of 3.1 +/- 1.2 mmHg which was significantly lower than the gradient of 6.6 +/- 3.5 mmHg of SJM prostheses. Residual murmur was documented in six patients, in three of whom, however, the murmur disappeared within one year following the operation.(ABSTRACT TRUNCATED AT 250 WORDS)

During the period February to December 1990, 52 adult patients were referred to our clinic for evaluation of the presence of the Marfan syndrome. In 24 out of 52 patients the Marfan syndrome was diagnosed. Cardiac abnormalities were found in all patients: mitral insufficiency because of mitral valve prolapse (83%), aortic dilatation (67%), aortic insufficiency (38%), tricuspid valve insufficiency with or without tricuspid valve prolapse (17%) and atrial septal defect (4%). In 3 patients an aneurysm of the ascending aorta was found. Early recognition of the Marfan syndrome is relevant for prevention of the life threatening complication of aortic dissection. In patients with valve abnormalities endocarditis prophylaxis is advised. A Marfan outpatient clinic offers optimal diagnostic possibilities.

A 53-year-old male was admitted to the hospital because of Candida albicans endocarditis. He had had a thoracoplasty due to pulmonary tuberculosis and showed severe restructive lung function. In 1987 and '89, trachiostomy was made because of respiratory failure. The patient was well until nine months earlier, when he consulted a physician because of fever. The investigations failed in finding the cause of the fever. He was administered antituberculosis agents and antiinflammatory drugs but had a fever every day. Two months before admission, a cardiac ultrasonographic study showed evident vegetations with mitral regurgitation. From the above course and examinations, a diagnosis of Candida albicans endocarditis was made. Infusions of CEZ, TOB, PIPC and miconazole for more than one month was ineffective. In November, 1990, he was referred to our medical center for the purpose of operation. A blood culture proved Candida albicans infection. An intravenous administration of fluconazole 400 mg/day was begun. However, there was pulmonary bleeding probably due to heparin used for prevention of atrial thrombosis and he developed fever, hypoexemia, ventricular tachycardia, and hyponatremia. He underwent mitral-valve replacement with a SJM valve. Culture of the vegetated mitral valve again proved Candida albicans. After operation, hypoexemia, ventricular tachycardia, hyponatremia were improved gradually. However he had an eosinophilia, eruption, and dyspnea. We suspected a drug eruption of fluconazole. Lymphocyte stimulating test of fluconazole proved positive. After the episode, he had no symptoms and was discharged.

Twenty-two patients with mitral insufficiency resulting from native valve endocarditis underwent mitral valve repair. Six patients had acute endocarditis with positive blood cultures and active valve infection. Sixteen patients were cured of active infection, but mitral insufficiency developed as a result of prior infection. Mean age was 48.5 +/- 21.7 years; 13 (59%) were male. Mean New York Heart Association functional class was 2.6 +/- 1.2. Multiple valve lesions were present in 11 (50%) patients. Valve abnormalities included leaflet perforation in 13 patients, chordal rupture or elongation in 14, vegetations in 5; and annular abscess in 1. In patients with acute endocarditis all macroscopically infected tissue was excised. Multiple techniques were required to achieve valve competence. Suture or patch closure of perforation was done in 14 patients, chordal shortening or transfer in 9, leaflet resection and closure in 4, leaflet resection with pericardial patching in 5, and annuloplasty in 15. Mitral valvuloplasty was combined with other procedures in 11 (50%) patients. There were two (9%) hospital deaths, both occurring in patients with healed endocarditis. There was one (9%) death in a patient undergoing an isolated procedure and one (9%) in a patient undergoing a combined procedure. Mean follow-up was 24 +/- 16.8 months and was complete. Seventeen (85%) were in New York Heart Association functional class I, and three (15%) were in class II. There were no late deaths, reoperations, recurrent endocarditis, thromboembolic events, or other valve-related morbidity. We conclude that mitral valve repair for insufficiency resulting from bacterial endocarditis (1) is possible in acute and healed disease, (2) has a low operative mortality, and (3) has resulted in patients free of recurrent infection and valve-related morbidity and mortality. Mitral valve repair is an attractive alternate to valve replacement in bacterial endocarditis.

In this report we study the value of ambulatory transesophageal echocardiography (TEE) in the clinical setting after a 2-year experience at our department. Since December 1988 until February 1991, 470 TEE examinations were indicated in 430 patients. Excluded were 8 cases, two out of them due to a formal contraindication and six who did not tolerate the procedure. The clinical indications for the examination, in the 462 studies performed, were as follows: possible cardiac source of emboli in 165 (35%); native mitral valve disease in 91 (20%); prosthetic valve dysfunction in 54 (12%); diseases of the aorta in 44 (10%); suspected infective endocarditis in 41 (9%); study of left ventricular function in 26 (6%); congenital heart disease in 18 (4%); tumor or intracardiac mass in 11 (2%); miscellaneous in 12 (2%). Based on this experience, we can conclude that TEE is a clinically useful technique for: 1) the study of mitral regurgitation, either native or prosthetic; 2) the detection of vegetations and abscesses in infective endocarditis; 3) the evaluation of a possible cardiac source of emboli; 4) the examination of the aorta in cases of suspected dissection; 5) the completion of the anatomic study in some congenital heart diseases, particularly after a surgical correction; 6) the study of patients with a technically inadequate transthoracic approach.

The article discusses the results of reconstructive valve-preserving operations in mitral insufficiency performed under conditions of hypothermic (27-25 degrees C) protection without perfusion in 114 patients. Depending on the valve morphological changes multicomponent intervention was under taken contemplating the performance of commissurotomy, chorda fenestration, resection and sewing of the cusps, removal of fibrous deposits from the cusps, resection of peripheral and intermediate chordae. The discrepancy between the cusp area and the perimeter of the fibrous ring was corrected in 99 patients by annuloplasty with sutures. The hospital mortality was 6.1%. Six-year postoperative survival was recorded in 91% of cases; no thromboembolic complications encountered in 97.4% of patients. The condition improved in most patients and they moved to NYHA Functional Class I-II. Unfavourable results were due to a severe initial clinical and functional condition and to the operations conducted in the active stage of septic endocarditis.

A case of intracranial mycotic aneurysm due to culture-negative infective endocarditis involving a patient with hypertrophic cardiomyopathy is reported. The patient, a 22-year-old woman with no history of known prior disease, had fever, headache and focal neurologic symptoms 3 days before admission. An echocardiogram performed after admission disclosed an obstructive hypertrophic cardiomyopathy and a gross vegetation on septal leaflet of mitral valve. Cerebral angiography revealed a mycotic aneurysm involving a peripheral branch of the left middle cerebral artery. Causal agent was not identified, and empiric treatment with penicillin G and streptomycin achieved medical cure and disappearance of the aneurysm 2 weeks later. Four months after endocarditis had been cured, the patient was electively operated because of progression of mitral regurgitation. Six months later, she is asymptomatic.

During January 1982 to June 1989, there were 105 evaluable adult cases of native valve infective endocarditis admitted to Department of Medicine, Siriraj Hospital. The incidence was approximately 2.6 per 1,000 admissions. The male to female ratio was 1.4 and the mean age was 31.6 years. Thirty (28.5%) were cases associated with intravenous drug abuse. All non-addicts had pre-existing cardiac lesions susceptible to endocarditis especially rheumatic mitral regurgitation, aortic regurgitation, VSD and PDA. The clinical features of cases without intravenous drug abuse were low grade fever for few weeks, malaise, dyspnea and heart murmur. The addicts with endocarditis presented with acute febrile illness and pulmonary symptoms. Mucocutaneous embolic lesions were detected in one third of the patients. Echocardiography detected vegetations in 50 per cent of the patients. Streptococci were the most common causative agent in 93 per cent of non-addicts whereas the same percentage in addicts were caused by S. aureus. Most of the patients were treated with beta lactams (pen G, ampicillin or cloxacillin) alone or combined with aminoglycosides (streptomycin or gentamicin) for a duration from 10 days to 16 week. Six cases had valve replacement operation due to intractable heart failure and valve ring abscess, 2 had embolectomy of major arteries and 2 had craniotomy due to intracerebral hemorrhage. The overall case fatality rate was 14 per cent. The causes of death were heart failure, cerebral complications and severe pulmonary infections. Clinical response was observed sooner in non-addict patients.

One hundred and fifty-five patients with isolated mitral regurgitation were referred from our Department of Cardiology for mitral valve repair between 1972 and 1990. Men were in the majority (59%), the mean age was 51 years and 61% of the patients were in NYHA class III or IV. Degenerative or dystrophic etiologies predominated, followed by rheumatic origins (17%) and bacterial endocarditis (14%). Surgical repair was performed using Carpentier's techniques: insertion of a prosthetic ring (87%) valvular resection (73%), valvular mobilization (11%), closure of a perforation (4,5%) and resection of vegetations (4,5%). Two patients died during surgery and 7 were lost to follow-up; the others were followed for an average of 4 years, i.e., a cumulative follow-up of 584 years/patients. The overall results at 11.5 years were satisfactory: 84.5% survival rate and 64.5% with good valvular function. The linearized rates of endocarditis, thromboemboli, hemorrhagic complications (51 patients were taking anticoagulants) and repeated interventions were, respectively: 0.35, 1.54, 0.17 and 2.05%/patient-year. Residual mitral regurgitation was sought by clinical and Doppler examinations: 55.5% of the patients had none, 26% had mild, 10.3% had moderate and 8.2% had severe regurgitation. Analysis of the latter two groups identified 3 influencing factors: rheumatic origin of the regurgitation, surgery on the anterior cusp and the year surgery was performed (the post-surgical incidence has decreased in recent years). Other, less-well-known complications were also found: left ventricular outflow tract obstruction, progressive evolution towards mitral stenosis, development of aortic regurgitation (usually discreet) and formation of left atrial thrombi.(ABSTRACT TRUNCATED AT 250 WORDS)

We evaluated 77 patients with symptomatic mitral stenosis for balloon valvuloplasty. Five patients were excluded from the procedure due to the presence of intra-atrial thrombi or mitral valve endocarditis as detected by 2D echocardiography. The mean age of the 72 treated patients was 38 +/- 11 years, 68 were NYHA functional class II or IV: only 6 patients had valvular calcification. Three patients had severe liver failure, 2 were chronic alcoholics, one had liver cirrhosis, 2 had severe weight loss and 13 had pulmonary hypertension at systemic levels. 69 patients had a technically adequate procedure, one patient died, 1 developed cardiac tamponade and 1 failed. Mitral valve area increased from 0.93 +/- 0.34 to 2.38 +/- 0.67 cm2. Mitral incompetence increased in only 16 patients. After a mean follow up period of 15 +/- 5 months (range 8 to 27), 56 patients remained in FC I or II. Mitral valve area remained satisfactory in 54 patients. Mitral valve anatomy evaluated by echocardiography is helpful to predict immediate and late outcome. We conclude that balloon mitral valvuloplasty is the first choice for patients with severe symptomatic mitral stenosis.
