[Prognosis of asymptomatic or slightly symptomatic chronic aortic insufficiency. Apropos of 54 patients followed for an average of 36 months].

A series of 54 patients with chronic aortic insufficiency with little (38) or no symptoms (16) were studied. All had severe regurgitation leading to discussion of aortic valve replacement. All patients (44 male and 10 female) underwent clinical, radiological, electrocardiographic, hemodynamic and angiographic investigation with assessment of left ventricular volume by monoplane 30 degrees cineangiography on entry to the study.

[Coronary bypass surgery. Results after 5 years : mortality - morbidity].

The improvement in the expectation and quality of life of patients undergoing coronary bypass surgery has been studied in the short term but there are relatively few studies with follow-up periods of over five years. The results in 239 patients operated on between 1970 and 1976 are presented. The preoperative data was obtained from a computerised filing system; studies were made at 3 months, at an average of 60 months, and in 78 patients with follow-up exceeding 5 years.

[Prognosis of primary non-obstructive cardiomyopathies].

The prognosis of congestive cardiomyopathy was studied in 132 consecutive patients (110 male, 22 female, average age 45 +/- 11 years) in whom a thorough clinical evaluation had excluded a secondary cause. The patients presented with left ventricular failure, a history of systemic embolism, syncope or radiological cardiomegaly. Right (100 p.
