Mitral Valve Surgery in Patients With Severe Mitral Annular Calcification.

Background: Mitral valve surgery in patients with severe mitral annular calcification can be challenging. We investigated surgical outcomes of mitral valve surgery with complete annular decalcification and reconstruction.

Methods: Between January 2004 and December 2013, 2,104 patients underwent mitral valve surgery at our institution.

[Mitral valve replacement in dextrocardia and situs inversus].

Cardiac surgery for acquired valvular diseases in patients with dextrocardia is extremely rare. We report a surgical case of mitral valve replacement and tricuspid annuloplasty in a patient with dextrocardia and situs inversus. A 74-year-old man with dextrocardia and situs inversus, who had undergone patch closure of atrial septal defect 25 years before, was referred for surgical treatment of severe mitral and tricuspid valve regurgitation.

Coronary arterial compression caused by an aneurysm of the sinus of Valsalva with aortic prosthetic valve endocarditis.

Myocardial ischemia caused by coronary arterial compression by an aneurysm of the sinus of Valsalva is a particularly unusual complication. We describe a patient with aortic prosthetic valve endocarditis complicated with an aneurysm of the sinus of Valsalva. An 82-year-old woman was admitted to our hospital with a high fever and chest discomfort.

Redo coronary artery bypass grafting: early and mid-term results.

Objectives: Redo coronary artery bypass grafting (CABG) has been gradually increasing in Japan. We prospectively collected redo-CABG data and evaluated these the early and remote results.

Methods: Between 01/01/1994 and 06/30/2002, a total of 71 patients underwent isolated redo-CABG in our hospital group.

Urgent off-pump coronary artery bypass grafting.

Objectives: The use of off-pump coronary artery bypass grafting (CABG) has become widespread, since it has proven less invasive and to promote early recovery. In this study, we investigated the efficacy of off-pump CABG in patients in the evolving phase of acute myocardial infarction.

Methods: Retrospective chart review was carried out for patients undergoing urgent isolated off-pump and on-pump CABG at Shin-Tokyo Hospital Group between January 1991 and June 2001.

Coronary artery bypass grafting in patients on chronic hemodialysis: diabetic nephropathy versus nondiabetic nephropathy.

Patients with both end-stage renal disease and diabetes mellitus carry an increased risk of coronary atherosclerosis. This study was performed to evaluate the perioperative and remote outcome of diabetic nephropathy patients on hemodialysis undergoing coronary artery bypass grafting (CABG). We retrospectively analyzed the results of CABG performed between September 1, 1993 and August 31, 2001.

Coronary artery bypass grafting using the gastroepiploic artery in 1,000 patients.

Background: The gastroepiploic artery (GEA) has been used as a graft in 1,000 patients in our institution, and the clinical outcome and the angiographic long-term results were reviewed.

Methods: Between June 1, 1991, and June 30, 2001, 1,000 consecutive isolated coronary artery bypass grafting procedures using the GEA were performed in the Shin-Tokyo Hospital Group. The perioperative data were retrospectively analyzed, and the late angiographic results, cardiac related events, and survival were examined.
