Clinical and serial echo Doppler follow-up of a new porcine bioprosthesis (medtronic intact)

Abstract:

To determine the pbkp_redictors of primary bioprosthetic heart valve failure(central valvular regurgitation, or non-thrombotic valve obstruction resulting in death or reopc*? ation) 49 preoperative, intra-operative and postoperative variables were analyzed in 291 adult male patients who were randomized to receive a bioprosthetic heart valve. The mean age at the time of operation was 60.227. 9 yrs. for aortic and 56.327. 1 yrs. for mitral valve replacement. At an average followup at 10 years, 20 patients developed primary valve failure(PVF). The probability of patients remaining free of PVF at average followup at 10 years was 0.95 f 0.02 for eorric and 0.78+ 0.07 for mitral valves. Age, ejection fraction, valve location, aortic cross clamp time, post pericardiotomy syndrome, post operative endocarditis. and long term snticoagulation were significant pbkp_redictors of PVF unfvariately. Multivariate(Cox Model) analysis to determine the …
