Long Term Results After Repair of Type A Acute Aortic Dissection According to False Lumen Patency.

Background. Late survival and freedom from retreatment on the descending aorta was evaluated after ascending aortic repair for type A acute aortic dissection (TAAAD). Methods. Between March 1992 and January 2006, 189 TAAAD patients (mean age, 52 11; range, 17 to 83 years) were included; of these, 58 had a patent false lumen, and 49 had Marfan syndrome. The descending aorta was evaluated postoperatively with computed tomography (CT). Late outcomes were assessed by Cox regression analysis and actuarial survival and freedom from retreatment by the Kaplan-Meier method. Mean follow-up was 88 44 months. Results. There were 38 (20%) late deaths. At 10 years, survival was 89.8% 2.1% for patients wi…

Clinical outcomes of aortic valve repair in asymptomatic patients with chronic severe aortic valve regurgitation.

inhaled prostacyclin,nitric oxyde and nitroprusside in pulmonary hypertension after mitral valve replacement

OBJECTIVE: Pulmonary hypertension increases morbidity and mortality in patients undergoing heart surgery. Mitral valve stenosis is frequently associated with an increase in pulmonary vascular resistance (PVR). Cardiopulmonary bypass exacerbates pulmonary hypertension in patients undergoing cardiac surgery. The aim of this study was to compare the hemodynamic effects of inhaled prostacyclin and nitric oxide and the administration of i.v. nitroprusside during cardiac surgery with a clinical, pharmacodynamic dose-response, prospective, randomized, and double-blind study (Group A: inhaled prostacyclin; Group B: inhaled nitric oxide; Group C: nitroprusside). MATERIALS AND METHODS: Fifty-eight pa…
