The clinical profile of 28 consecutive patients admitted with infective endocarditis (IE) between 1987 and 1988 was studied. There were 21 males and seven females with a mean age of 24 +/- 11 years. Rheumatic heart disease (RHD) was the commonest underlying disease (68%) followed by congenital heart disease (CHD). Mitral regurgitation with aortic regurgitation were the commonest valvular lesions (47%) in those with RHD while ventricular septal defect was the commonest (43%) in those with CHD. A younger age of onset, complicated course and high mortality were seen in these six patients with acute IE. Persistently positive blood cultures during life or at autopsy were obtained in 21%. Strep viridans was the commonest isolate and was often resistant to streptomycin. 2D echocardicgram revealed vegetations in 96% of patients, the aortic valve (39%) being more commonly affected than the mitral valve (11%). ESR of more than 20 mm drop 1st hour (Wintrobe) was seen in 96%. Thrombophlebitis was a common complication of therapy and cloxacillin the commonest drug implicated. A mortality of 21% as a result of refractory congestive heart failure (CHF) (50%), uncontrolled sepsis (33%) and embolic events (17%) was seen. A rising incidence of culture negative IE, combined aortic and mitral valve disease and CHF is noted.

A 13-year-old girl was admitted to a hospital because of fever and sore throat. Staphylococcus aureus was obtained on blood culture, and she was treated with antibiotics under the diagnosis of sepsis and DIC. Echocardiography showed huge vegetation attached to the posterior leaflet of mitral valve and severe mitral regurgitation. CT scan revealed multiple heterogeneous high density areas in her brain. She was transferred to our hospital for further examination and treatment. Large verrucae on the mitral valve, severe regurgitation and repeated embolism urged us to the emergency mitral valve replacement. Debridement of abscess on the posterior wall of the left atrium and ventricle necessitated patch plasty of those structures and mitral ring as well. Operative and postoperative examination showed mycotic aneurysm of right coronary artery, multiple brain hemorrhage, arterial obstructions of extremities and splenic infarction. Sooner she recovered except for slight macular degeneration caused by retinal embolism.

Clinical data from 186 patients (133 males and 53 females) with 190 episodes of infective endocarditis (IE) occurring between January 1981 and July 1991 were studied retrospectively at a large referral hospital in Northern India with the intention of highlighting certain essential differences from those reported in the West. The mean age was much lower (25 +/- SD 12 years, range 2 to 75 years). Rheumatic heart disease was the most frequent underlying heart lesion accounting for 79 patients (42%). This was followed by congenital heart disease in 62 (33%) and normal valve endocarditis in 17 (9%). Twenty-four patients had either aortic regurgitation (n = 15) or mitral regurgitation (n = 9) of uncertain etiology. Prosthetic valve infection and mitral valve prolapse were present in only 2 patients each. A definite predisposing factor could be identified in only 28 patients (15%). Postabortal sepsis and sepsis related to childbirth accounted for 6 and 5 cases, respectively. Only 1 patient had history of intravenous drug abuse. Two-dimensional echocardiography showed vegetations in 121 patients (64%). Blood cultures were positive in only 87 (47%), with a total of 90 microbial isolates. Commonest infecting organisms were staphylococci (37 cases) and streptococci (34 cases). Except for a significantly higher number of patients with neurologic complications in the culture-negative group, there were no differences between patients with culture-positive and culture-negative IE. Of the 190 episodes of IE, the patients had received antibiotics before admission in 110 (58%) instances. A significantly greater number of culture-negative patients had received antibiotics than did culture-positive patients (87 vs 23, p < 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

A 17-year-old woman with mitral and tricuspid valve prolapse and myxomatous degeneration presented puerperal infection by Staphylococcus aureus with clinical picture of sepsis and multiple septic embolism (right eye, left thumb, spleen, and left calf). She underwent total hysterectomy on the 10th day postdelivery and right eye enucleation on the 16th. Temporary total AV block occurred on the 14th day with temporary external pacing during the next couple of days. Acute endocarditis with acute mitral regurgitation was diagnosed on the 13th day, demanding immediate valve replacement. On the 46th day she developed moderate tricuspid valve regurgitation due to another episode of endocarditis. Final clinical discharge took place on the 62nd day after antibiotic therapy completion.

Left ventriculography (LVG) was performed to assess severity of mitral regurgitation (MR) on a scale of 0-4+ in 157 patients before and immediately after percutaneous mitral balloon valvotomy (PMV). There were 129 women and 28 men aged 51 +/- 1 (range 13-87) yr. With PMV, mitral valve area increased from 0.9 +/- 0.1 cm2 to 2.0 +/- 0.1 cm2 (P less than .0001). Increase in mitral regurgitation (MR) occurred in 69 patients (44%). Patients were divided into two groups based on increase in MR after PMV. Group A (n = 136) had 0-1+ increase in MR. Group B (n = 20) had greater than or equal to 2+ increase in MR after PMV. The only predictor of increase in MR greater than or equal to 2+ was the ratio of effective balloon dilating area to body surface area (EBDA/BSA). EBDA/BSA was 4.0 +/- 0.1 cm2/m2 in Group A vs. 4.37 +/- 0.2 cm2/m2 in Group B (P = .02). Follow-up of patients in Group B showed: Four patients remained NYHA Class III and required mitral valve replacement 4.3 +/- 1.1 (range 5-21) mo after PMV. One patient who had undergone combined aortic and mitral valvotomy died in the hospital of worsening heart failure. One patient died 1 mo later of sepsis related to a dental abscess. Follow-up of the remaining 14 patients at 9.5 +/- 1.1 (range 2-7) mo showed 10 in NYHA Class I and four in NYHA Class II. Eight of 15 patients (53%) who had repeat left ventriculogram at 9.0 +/- 0.8 mo after PMV had a decrease in MR of one grade when compared to LVG immediately after PMV.

From 1974 to 1984, 46 patients underwent emergency surgery for acute native valve endocarditis. Urgent valve replacement was necessary because of rapid hemodynamic deterioration in 34 (73%), uncontrolled sepsis plus heart failure in 9 (19%), and life-threatening emboli in 3 (7%) patients. At the time of surgery 23 patients (50%) were in NYHA functional class IV, 20 in Class III, and 3 in class II. Streptococcus was the most common organism encountered, followed by staphylococcus. Thirty-four cases presented severe aortic regurgitation, 3 mitral incompetence, 8 mitral plus aortic insufficiency, and one aortic plus tricuspid insufficiency. Operative mortality rate was 17% (8/46). Most deaths were due to preoperative multiple system deterioration, especially in cases with lesions of both the aortic and mitral valves, and were unrelated to the duration of preoperative antibiotic therapy. The postoperative observation period of long-term survival is from 6 to 102 months (= 44 months). There were 7 late deaths. The actuarial survival, including operative mortality, is 67%. Twenty-two patients are now in NYHA class II, 6 in class III. The duration of postoperative antibiotic treatment (6 weeks in our series) seems to be important for the prevention of reinfection, early surgery is of great benefit; our 31 survivors showed an excellent clinical improvement.

The efficacy of cryosurgery alone was evaluated in 15 patients with refractory monomorphic sustained ventricular tachycardias related to inferior wall infarction. Patients were 64 +/- 9 (SD) years old and had a mean left ventricular ejection fraction of 39.2 +/- 11.2%. Thirty different tachycardias were mapped with the origin localized to the septum or inferior wall in 20 (67%), near the mitral valve anulus in 6 (20%) and at the base of the posterior papillary muscle in 4 (13%) tachycardias. Endocardial cryoablation of these sites was performed with 6 to 13 (mean 9.2 +/- 1.8) cryolesions per heart. No mitral valve replacement was performed. There was one postoperative death as a result of sepsis. Cryoablation abolished inducible ventricular tachycardia in 11 patients. Of the other three patients, the tachycardia in two was controlled with a single antiarrhythmic agent that had previously failed to suppress inducible ventricular tachycardia. Thus, clinical success was obtained in 13 (93%) of 14 patients. The remaining patient received an automatic implantable cardioverter defibrillator. Ejection fraction remained unchanged or improved after surgery in 14 patients (93%). There have been no late deaths, recurrence of sustained ventricular tachycardia or significant mitral regurgitation during a mean follow-up period of 19 +/- 7 months. These results compare quite favorably with those previously reported for subendocardial resection alone, and indicate that cryosurgery is highly effective, does not result in deterioration of left ventricular function and preserves mitral valve competence when cryoablation of the posterior papillary muscle is necessary.

Since 1973, 11 patients have had emergency valve replacement for severe mitral insufficiency and cardiogenic shock within 1 month (mean 10.0 days) of acute myocardial infarction. Mean age was 60 years (range 44 to 71 years). Nine infarcts affected the inferior wall, one patient had a prior myocardial infarction, and only two patients had a history of cardiac symptoms. Ten patients had pulmonary edema, five were oliguric (less than 0.5 ml/kg/hr for 12 hours), four required endotracheal intubation, nine required preoperative intra-aortic balloon support, and three had had a cardiac arrest. Preoperative cardiac index averaged 1.7 L/m2/min even with pharmacologic and circulatory support. Eight patients had cardiac catheterization and nine had echocardiograms. Left ventricular ejection fraction varied from 23% to 83% (mean 51%) and was not prognostic. Five patients had papillary muscle rupture and six patients had papillary muscle dysfunction. The mitral valve was replaced with a mechanical prosthesis in all patients. Five had simultaneous coronary artery bypass grafts. Three of five patients with papillary muscle rupture and two of six with papillary muscle dysfunction survived hospitalization. Two patients could not be weaned from cardiopulmonary bypass, two patients died within 24 hours of low cardiac output, and two patients died 3 weeks postoperatively of acute tubular necrosis and sepsis following prolonged preoperative cardiogenic shock. The interval from onset of shock to operative therapy averaged 1.7 days for survivors versus 9.3 days for nonsurvivors. Although the amount of viable left ventricular mass cannot be measured preoperatively, we recommend early operation, before other organ systems fail, for patients having severe mitral insufficiency and cardiogenic shock within 30 days of acute myocardial infarction.

There have been many techniques applied to the repair of mitral valve prolapse, and the method used in a particular case is usually selected according to the position and extent of the lesion. To simplify and standardize the technique of mitral valve repair, we have adopted the resection, sliding plasty and ring annuloplasty methods since December 1992. Of 10 consecutive surgical cases, 2 involved prolapse of the anterior leaflet, 1 the posteromedial commissural, and 7 the posterior leaflet. One patient with posterior leaflet prolapse required valve replacement due to dehiscence of the plastied site on the 3rd postoperative day, and one died because of sepsis. However, the remaining patients were doing well without mitral regurgitation at a mean of 20 months (range: 8-32) after the operation. The advantages of these techniques include easy adjustment of the height of the leaflet and a good chance of long-term durability, since the affected lesion is resected.

Optimal timing of surgery in infective endocarditis (IE) depends mainly on the haemodynamic tolerance of the patient. Emergency surgery is required in cases of refractory heart failure due to valvular lesions, intracardiac fistulas and high grade cardiac conduction abnormalities caused by septal abscesses. Surgery must be considered in all patients who have undergone a transient episode of heart failure such as a pulmonary oedema and it must be early--within 2 or 3 weeks of starting antibiotic therapy in patients with aortic regurgitation. Bacteriological indications are less frequent: persistent sepsis beyond the first week in spite of medical therapy, mycotic IE or prosthetic valve endocarditis caused by Gram-negative or staphylococcal organisms. Some complications may swing the argument in favour of surgery: detection of root abscesses or mycotic aneurysms using transoesophageal echocardiography, and systemic embolisms with persistent, large and mobile vegetative lesions. Mortality rate depends on the haemodynamic status but also on the severity of anatomical lesions, on the type of endocarditis (native or prosthetic valve), on the type of surgery and on bacterial aetiologies. It varies between 5% and 30%. The late postoperative outcome is good. The actuarial survival rate at 8 years was 70% in our series of 31 patients with aortic regurgitation and early surgery. In mitral regurgitation, conservative surgery is possible in most cases. In our department, 48 patients with mitral bacterial lesions have been operated on with conservative surgery without operative mortality. IE was active in 14, recent in 12 and had occurred earlier in 22.(ABSTRACT TRUNCATED AT 250 WORDS)
