Remplacement valvulaire aortique associe au pontage cronaire

ABSTRACT

The progress achieved in the cardiac surgery and resuscitation fields allowed an enlargement of surgical indications to invalue inoperable patients. A typical example is the association of aortic valve stenosis with coronary stenosis in elder patients. The authors report a series of 6 male patients who underwent an aortic valve replacement associated with coronary artery bypass grafting [CABG] at the cardioc surgery department "B", between May 1996 and May 2003. The average age was 64,5 years [52-74]. All of them had a significant and symptomatic aortic valve stenosis. One patient had left ventricular dysfunction. All the patients had a stable hemodynamic status in the preoperative period. Five patients benefited from bioprosthesis valve, while the 6th patient had a mechanical one. The mean number of bypass was 2,1 per patient. The mean time of aortic cross clamp was 97min. Hospital mortality was nil. One patient developed acute renal insufficiency, while an other suffered from myocardial infarction and pulmonary infection. The aortic valvular replacement associated with CABG is a highly risk surgery. The operative indications that give best prognosis depend on the age factor [less than 70 years] and timing factor of surgery [suitable timing]
