[Cardiac valvular surgery after 65 years of age].

252 symptomatic patients aged 65-79 underwent surgery between 1970 and 1982 for heart valve lesions. Hospital mortality was 11.8%. Analysis of the short and long term results justifies cardiac surgery in elderly patients with valve disease.

Factors influencing postoperative survival in aortic regurgitation. Analysis by Cox regression model.

From 1965 to 1981, 114 patients underwent aortic valve replacement for severe aortic regurgitation in our institution. Catheterization was performed preoperatively in 103 patients. Follow-up was possible in 98% of the survivors. Long-term survival was significantly different between patients in preoperative Functional Class I-II and those in Class III-IV (p less than 0.03); those with a preoperative cardiothoracic ratio less than 0.64 versus greater than or equal to 0.64 (p less than 0.001); and those with a preoperative ejection fraction greater than 0.50 versus less than or equal to 0.50 (p less than 0.03). A multifactorial analysis was used to identify the dominant preoperative prognostic variables affecting survival. Three of the 13 parameters examined simultaneously were found to independently influence survival rates: cardiothoracic ratio (p = 0.001), strain pattern on the electrocardiogram (p = 0.072), and left ventricular end-systolic pressure (p = 0.127). After stratification of the population into two groups according to preoperative functional class, the predictive variables were cardiothoracic ratio (p = 0.014), strain pattern (p = 0.050), and acute/chronic form of aortic regurgitation (p = 0.034). This statistical analysis enabled us to derive a mathematical equation for predicting an individual patient's probability of survival. We found a close fit between the survival rate predicted by the mathematical model and the observed survival rate.

[Mitral valve replacement in an infant with disseminated lupus erythematosus and Libman-Sacks endocarditis].

The authors report a case of Libman-Sacks endocarditis of the posterior mitral leaflet in a child treated for disseminated lupus erythematosus for 8 years. Mitral valve replacement was performed. Libman-Sacks vegetations are hardly ever recognised in vivo and have never been previously reported in a child. The incidence of this cardiac complication of lupus erythematosus is probably higher than indicated in the literature. Attentive cardiac examination and systematic echocardiography should be part of routine follow-up of patients with disseminated lupus erythematosus.

Review of 387 isolated mitral valve replacements by the Model 6120 Starr-Edwards prosthesis.

Between February, 1965, and July, 1980, 387 patients underwent an isolated mitral valve replacement with the non-cloth covered Starr-Edwards ball valve (Model 6120) at the University of Louvain. The mean age of the patients was 48.765 years. The overall operative mortality was 6.1%. The mean age of the patients who died was 52.3 years and all but four were in New York Heart Association (NYHA) Functional Class III or IV. The actuarial survival rate is 78% at 5 years after operation, 72% at 10 years, and 70% at 13 years. The overall incidence of thromboembolic complications is 3.4% per patient-year with a total follow-up of 1,675 patient-years. Valve dysfunction has never occurred, and endocarditis, hemolysis, and paravalvular leakage have never reached a significant incidence. Hemodynamics investigations show a residual diastolic gradient of 6.6 mm Hg for the size 3M valves and 7.92 mm Hg for the size 2M valves. These current data over an extended follow-up interval (15 years) indicate that the Starr-Edwards Model 6120 prosthesis continues to perform satisfactorily in terms of mortality and morbidity, and there have been no instance of late failure due to valve dysfunction.

Twelve year results with a caged-ball mitral prosthesis.

Over a 12 year period in 230 patients mitral valve replacement was performed using the model 6120 Starr-Edwards prosthesis. Operative mortality was 6.5%, mean follow-up of the operative survivors was 3.9 years. Estimated late survival rate was 80% at 5 years and 73% at 12 years. 38% of late deaths were considered valve-related. Under routine anticoagulation thromboembolism occurred at a rate of 4.7% per patient-year with a fatal thromboembolic incidence of 1.4% per patient-year. In comparison with data available on other currently used prosthetic valves it appears that the rates of valve-related complications are quite similar, with the 6120 Starr-Edwards model being subject to the longest follow-up.

[Aortic valve replacement at the cardiac insufficiency stage].

80 adult patients with isolated aortic valvulopathy and cardiac insufficiency have been investigated. Among 10 non operated patients, there has been 9 deaths during a three years follow-up. Among 70 operated patients early mortality is not higher than among patients without cardiac failure, but late mortality is significantly higher (27, 1 p. 100), bacterial endocarditis and sudden deaths being particularly frequent. Subjective improvement is constant among survivors but cardiomegaly and left ventricular hypertrophy do not change much. The authors think aortic valve replacement is beneficial even in patients with cardiac failure.

[Intralobar sequestration causing heart failure in a new born infant. Surgical correction].

The authors report the occurrence of an intralobar pulmonary sequestration in a neonate with symptoms of congestive heart failure, due to a fistula effect in the sequestrated area. The venous drainage was directed mainly to the superior caval vein via azygos vein and accessorily to the left atrium. The patient became asymptomatic after lobectomy performed at the age of 11 days.
