To compare the efficacy of Carpentier's tricuspid annuloplasty with De Vega's, we prospectively randomized 159 patients, operated upon between January, 1977, and January, 1980, to one of the two techniques: 76 patients were assigned to the Carpentier group and 83 to the De Vega group. The criterion for inclusion in the study was the presence of moderate to(More)
We report two cases in which the pertinent angiographic studies disclosed the presence of hydatid cysts of the left ventricle, producing complete obstruction of the left anterior descending coronary artery in one patient and of the left anterior descending coronary artery and the circumflex coronary artery in the other patient. Both patients were(More)
BACKGROUND The purpose of this study was to compare medication use and complication rates between Crohn's disease (CD) and non-CD patients undergoing ileocolic resections and right hemicolectomies. METHODS A review of patients who underwent ileocolic resections and right hemicolectomies from January 1, 2003, through December 31, 2010, was performed. Data(More)
Within 30 days of acute myocardial infarction, 108 consecutive patients underwent urgent surgical myocardial revascularization for postinfarction angina between July 1976 and March 1983. There were 84 men and 24 women whose mean age was 59.6 +/- 9.5 years (range 34 to 80). Group I (15 patients, 14%) underwent surgery within 48 hours, Group II (47 patients,(More)
A study evaluating the durability of two recent techniques of tricuspid annuloplasty was conducted simultaneously in two institutions. One group working in Madrid, Spain, used Carpentier's ring in 32 patients. The other in Montreal, Canada, employed De Vega's semicircular annuloplasty in 17 cases. Competence of the tricuspid valve was obtained in nearly all(More)
A series of 66 consecutive patients operated on for postinfarction ventricular aneurysm is reviewed with regard to the factors influencing the progressive decline of mortality (3.2% in the last 31 patients seen). The method of myocardial protection has a significant influence on mortality, which was 45% in patients operated on with aortic cross-clamping(More)
The Angell-Shiley porcine xenograft was evaluated in 48 asymptomatic subjects who underwent cardiac catheterization an average of 14 months after operation. Nineteen patients had mitral and 29 had aortic valve replacement. The average mitral valve gradient was 8 +/- 3 mm Hg and the average effective orifice area was 1.8 +/- 0.6 cm2. The average aortic valve(More)
A case of successful surgical treatment of double outlet left ventricle is reported. In a 7 year-old patient with this rare congenital cardiac malformation, situs solitus of the viscera and atria and concordant connexion of atria and ventricles, d-malformation of the great arteries with the aorta to the right and slightly posterior to the pulmonary artery,(More)
