Use of the Carpentier-Edwards porcine bioprosthesis: assessment of a patient selection policy.

The Carpentier-Edwards bioprosthesis was implanted in 369 patients (414 valves) between May 1977 and December 1987 (age 67.2 +/- 0.5 years); 242 had aortic valve replacement, 80 had mitral valve replacement, 44 had multiple valve replacement, of which 41 were aortic and mitral valve replacement, 2 had isolated tricuspid valve replacement, and 1 had a pulmonary valve replacement.

Surgical repair of coarctation of the aorta in infants under one year of age. Long-term results in 146 patients comparing subclavian flap angioplasty and modified end-to-end anastomosis.

Between July 1976 and February 1991, 146 consecutive infants underwent surgical repair of coarctation of the aorta. Age at operation varied from 2 days to 11 months (median 1 month). Ninety-two (63%) were less than 2 months.

A comparison of the inotropic effects of dopamine and epinine in human isolated cardiac preparations.

The positive inotropic effects of epinine and dopamine have been studied in isolated preparations obtained from human heart in the absence and in the presence of the selective beta adrenoceptors antagonists practolol and ICI 118,551. ED50 values of the two agonists were similar (about 3 x 10(-5) M). The inotropic efficacy of epinine was significantly higher than that of dopamine in adult ventricular and papillary muscles, it was similar to that of dopamine in juvenile myocardial preparations and in adult atria and pectinate muscles.

[Revision of midline sternotomies after cardiac surgery in 1988: retrospective study].

Twenty-three of 514 (4.6%) patients who underwent cardiac surgery in 1988 with cardiopulmonary bypass were later reoperated for sternal complications. Several risk factors, including pre-, intra and postoperative variables, have been investigated.

Surgical treatment of subvalvular aortic stenosis. Long-term results.

From 1966 till May 1988, 53 patients underwent surgery for fixed subaortic stenosis. Subvalvular obstruction was isolated in 27 patients (Group I) and associated with aortic valve lesions in 26 (Group II). A membranous stricture was documented in 5 patients and a fibromuscular ring in 48.
