Background. Allograft aortic valve replacement has gained widespread acceptance. However, there is little information about in vivo allograft valve function at rest and during exercise. Methods. Cardiac catheterization was performed to measure hemodynamic variables at rest and during supine bicycle exercise in 44 patients who had had aortic valve r...

Background. There is the potential for left ventricular outflow obstruction when small aortic valve bioprostheses are employed in normal-sized or large adults. It has been hoped that bovine pericardial valves would improve hemodynamic performance in the smaller tissue valve sizes. Methods. To determine in vivo hemodynamic performance of heterograft...

Aortic valve replacement was performed through a left anterolateral thoracotomy using cardiopulmonary bypass in a 59-year-old man who had previously received esophageal resection with substernal reconstruction by gastric tube. Through this approach, injury of the reconstructed tube was avoided and the valve replacement operation was safely performe...

We report a case of methicillin-resistant Staphylococcus aureus-induced prosthetic valve endocarditis, which was successfully treated with aortic valve replacement using the Freestyle stentless bioprosthesis. The total root and stentless design of this bioprosthesis allows for more radical removal of infected tissue and easier treatment for annular...

Background. Minimally invasive surgical approaches have been applied recently in the management of valvular heart disease. In this report, we reviewed our preliminary experience of minimally invasive aortic valve replacement. Methods. Eighteen patients were operated on by means of an “I” ministernotomy, and 16 patients were operated on by means of ...

A patient with aortic regurgitation and idiopathic thrombocytopenic purpura underwent a successful valve replacement. Cardiac surgery requiring a cardiopulmonary bypass in idiopathic thrombocytopenic purpura can be safely carried out with the preoperative intravenous administration of high-dose gammaglobulin, which may thereby reduce the need for e...

A 59-year-old man with a history of the thoraco-abdominal esophagus resection with retrosternal gastric tube reconstruction for esophageal cancer complicated by anastomosis leakage and purulent pericarditis was admitted for aortic regurgitation due to infective endocarditis. Floppy vegetation and worsening cardiac failure indicated aortic valve rep...

Es wird über eine junge Patientin berichtet, die sich nach bereits erfolgter offener Aortenklappenkommissurotomie und nachfolgendem Klappenersatz mit Perikardpatcherweiterung der Aorta ascendens einem erneuten Aortenklappenersatz unterziehen mußte. Im Bereich der Perikardpatcherweiterung hatte sich im Verlauf der Jahre ein Aneurysma ausgebildet. Di...

Objective: This clinical study was designed to evaluate the postoperative cardiac function in patients after aortic valve replacement for aortic valve disease with increased left ventricular mass.Methods: Aortic valve replacement was performed in 117 patients using the St. Jude Medical valve. Their valve lesion was aortic regurgitation in 71, and a...
