Surgical repair of the pulmonary trunk aneurysm.

Objective: Aneurysm formation of the pulmonary trunk is rare and there is controversy about optimal treatment for this disease. The aim of this article is to report four patients with pulmonary trunk aneurysm which were managed by surgical repair.

Materials And Methods: From 1986 to 1997, we performed surgical repair for pulmonary trunk aneurysm in four patients.

[Surgical results of coronary artery bypass grafting in patients older than 75 years].

We studied 19 patients, all older than 75 years of age, who had isolated coronary artery bypass grafting (CABG) from January 1990 to December 1996. Clinical characteristics, hospital mortality and long-term survival were compared between this elderly group (> or = 75 years) and a younger group (60-74 years) in which 130 consecutive patients underwent the same procedure during the same period. There were no differences of coronary risk factors, renal function, respiratory function and ejection fraction between the two groups.

[A successful emergency reoperation of thrombosed CarboMedics valve in the mitral position].

We report a successful emergency reoperation of a thrombosed CarboMedics valve five years after the original implantation of the prosthesis. A 53-year-old mentally retarded woman suffered acute heart failure due to a thrombosed CarboMedics valve, which was caused by inadequate control of anticoagulants. The patient was reoperated on immediately after thrombolytic therapy failed to show an improvement in leaflets' excursion.

[Maze operation for chronic atrial fibrillation with valvular heart diseases].

Between July 1994 and August 1995, 14 patients underwent combined modified maze procedure and valvular surgery including 5 patients having reoperation. Associated procedures were performed with mitral valve operation (n = 13), tricuspid annuloplasty or valve replacement (n = 9) and aortic valve replacement (n = 4). Duration of atrial fibrillation (AF) varied from 1 to 18 years (mean 8.

Mitral valve operation after percutaneous transvenous mitral commissurotomy (PTMC): an evaluation of PTMC indications based on intraoperative findings.

Six patients underwent open heart surgery for mitral valve disease after percutaneous transvenous mitral commissurotomy (PTMC) because of recurrent mitral stenosis (MS) in 4, moderate mitral regurgitation (MR) in 1, and acute severe MR in 1. These 6 patients were the only such observed cases out of a total of 86 patients who presented with PTMC in our hospital between October 1989 and May 1995. The duration of the subjective symptoms related to heart failure was 24.
