[Early surgery in patients with native valve endocarditis]. / Chirurgie de l'endocardite sur valves natives à la phase active.

Between January 1990 and December 2006, 93 patients with infective endocarditis on native valves were operated in the active phase of the disease. The average age of our patients was 32 years with a male ascendancy. The causal heart disorder was found in 89 % of the cases, dominated by rheumatoid arthritis. The germ in cause was isolated in 52.6 % of the cases. The operative indication was hemodynamic in 29 cases, infectious in nine cases, mixed in 29 cases and embolic in 26 cases. The average operating delay was of 13 days with regard to the beginning of the antibiotic treatment. We realized a valvular aortic replacement at 32 patients with reconstruction of the ring in six cases, a valvular mitral replacement at 29 patients, a mitroaortic replacement at 21 patients, a reconstructive mitral surgery in nine cases, a valvular tricuspid replacement in one case and a reconstructive tricuspid surgery in one case. The early mortality was 13 %. The follow-up was 89 % with an average recession of 3.1 years and a late mortality of 5 %. The aim of this study is to analyze the immediate and late results of the surgery of infective endocarditis in the active phase and to bring to light the prognostic factors of mortality.

[Coronary artery fistula: case report and review of the literature]. / Fistule coronaire : rapport d'un cas opéré et revue de la littérature.

The coronary fistula is a rare abnormality making communicate a coronary artery with a cardiac cavity or a great vessel, so bypassing the myocardial capillary network. The majority of these fistulas are congenital but can nevertheless arise after a cardiac surgery. The right coronary artery and the left anterior descending coronary artery are mostly concerned. The circumflex coronary artery is rarely involved. The most frequent site of drainage is the right ventricle. We report the case of a 2-year-old child, brought by his parents for dyspnoea of effort. The diagnosis of coronary fistula was confirmed by the coronary angiography which showed an aneurysmal circumflex artery, draining into the right ventricle. The intervention was led under cardiopulmonary bypass. We proceeded to the longitudinal opening of the aneurysm then to the blindness of the fistula. The postoperative course was simple.
