Objective: To summarize and critically appraise the world experience with homografts in mitral tricuspid valve surgery.Methods: We conducted a systematic review according to PRISMA criteria. searched following terms available databases, such as PubMed (National Center for Biotechnology Information), Cochrane Library, Web of Science (Clarivate), Google Scholar: ((mitral homograft) OR (tricuspid ...

OBJECTIVES The aim of this prospective study of adult patients operated with a cryopreserved aortic homograft was to use serial echocardiographic data to evaluate the postoperative hemodynamic performance of these valves. BACKGROUND Only limited data on hemodynamic performance of aortic homografts at rest and during exercise are available. Controversy also exists regarding incidence and progr...

The fate is described of 11 patients who had a stored pulmonary valve homograft mounted on a frame or in a Dacron jacket used for mitral valve replacement. Mitral regurgitation due to holes in the attenuated cusps occurred in nine by one year, requiring re-operation or causing death. Only one patient remains well with moderate mitral regurgitation after two years. Since January 1967, 118 patien...

The course of hypertension within the first 2 months after kidney transplantation was correlated with renal function, plasma renin activity (PRA), and the daily maintenance dose of prednisone in 18 homograft recipients. During acute rejection blood pressure (BP) closely correlated with PRA. Patients with normal homograft function showed an increase in BP early after transplantation which in mos...

A case is described of a 27-year-old woman whose aortic valve was replaced by a homograft. Eighteen months after the operation she gave birth to a normal healthy girl.

Our experience with homograft replacement of the aortic valve now includes 175 patients operated on over a period of almost three years, and we have come to aceept this method as the best surgical treatment for aortic incompetence and for calcific aortic stenosis. As others continue to use a ball valve prosthesis, it is important to analyse the results with the homograft valve, paying particula...
