Delamination of Acuseal arteriovenous graft: Two case reports.

Acuseal arteriovenous graft is an early cannulation graft having a tri-layered structure with an elastomeric middle layer. However, delamination of Acuseal grafts has been reported recently. This article describes two cases with different characteristics of Acuseal delamination.

Long-term results of mitral valve replacement: biological xenograft versus mechanical valves.

We studied 279 patients who underwent mitral valve replacement at the Department of Thoracic and Cardiovascular Surgery, Hyogo College of Medicine, between November 1973 and December 1998. The patients were divided into two groups based on the type of replacement valve (154 patients in the biological xenograft group and 125 patients in the mechanical valve group), and the long-term results were compared. Clinically satisfactory results were obtained in both the biological xenograft group and the mechanical valve group according to the surgical results, long-term survival, and incidence of prosthetic valve endocarditis.

Successful aortic valve replacement for severe aortic regurgitation combined with annular abscess due to active infected endocarditis: usefulness of gelatine-resorcine-formol biological glue in remodeling the new aortic annulus.

Two men, 58 and 72 years old, were diagnosed as severe aortic regurgitation complicated by aortic annular abscess due to active endocarditis infection diagnosed by echocardiography. We conducted aortic valve replacement using gelatine-resorcine-formol biological glue to close the abscess cavity and remodel the new aortic annulus. Although 1 man developed complete atrial-ventral blockage postoperatively and required that a permanent pacemaker be implanted, neither experienced recurrence of infectious peri-valvular leakage.

Angiosarcoma of the pericardium. Review of 9 reports from Japan.

A 35-year-old woman diagnosed with a cardiac tumor by echocardiography and cinecardiography underwent surgical excision in December 1988. The port-wine tumor had invaded from the surface of the right atrium to the anterior wall of the right ventricle, preventing us from removing it completely. Pathohistologically, it was diagnosed as angiosarcoma of the pericardium.

Accessory mitral valve associated with aortic regurgitation in an elderly patient: report of a case.

We encountered a 75-year-old man who complained of exertional dyspnea. An echocardiographic examination showed aortic regurgitation and a tumor in the left ventricular outflow tract. Under complete extracorporeal circulation, we surgically made an incision of the ascending aorta with a slight thickening of the aortic valve and an enlarged annulus.

The long-term follow-up results of elective surgical treatment for abdominal aortic aneurysms.

This study was aimed at evaluating early and long-term follow-up results of surgical reconstruction of infrarenal abdominal aortic aneurysms (AAA). A consecutive series of 392 patients who underwent elective abdominal aortic repair from 1974 to 2000 was reviewed retrospectively. The mean age was 69.
