The purpose of this retrospective study is to evaluate the long-term performance of the Liotta minimally intrusive bioprosthesis (MIB) and to identify its most important risk factors. From January 1980 to March 1982, 73 patients (30 males and 43 females; mean age 45.5 years +/- 11.7 standard deviation; range 11 to 64) underwent operation for heart valve replacement with an MIB. Fifty-two mitral valve replacements (MVR), 16 aortic valve replacements (AVR), 4 mitral and aortic valve replacements (MAVR), and 1 mitral and tricuspid valve replacement (MTVR) have been performed (78 MIBs implanted). Global operative mortality has been 8.2% (6/73): 9.6% (5/52) for MVR and 6.2% (1/16) for AVR. The 10-year follow-up reaches 519 patient-years and 581 valve-years, and is 96.5% and 93.9% complete, respectively. Actuarial freedom from any patient- or valve-related event has been calculated at one time with its hazard function and its incidence normalized per 100 patient- and/or valve-years; statistical significance of difference between curves has been assessed. In this report, overall actuarial survival at 10 years is 79.4% +/- 5.3% SEM (standard error of the mean), including operative deaths (incidence = 2.6% per patient-year). Two patients experienced periprosthetic leakage (PL) at 4 and 9 years, respectively (incidence = 0.4% per valve-year). One patient underwent reoperation because of otherwise untreatable prosthetic valve endocarditis (PVE) at 5 years (0.2% per valve-year).(ABSTRACT TRUNCATED AT 250 WORDS)

The Authors present four cases of embolism of the superior mesenteric artery treated surgically, with satisfactory results, through embolectomy with Fogarty's catheter. The Authors affirm the necessity of always following this type of intervention, given its simplicity and the high rate of mortality of non treated embolism. Some anatomical and physio-pathological considerations are remembered and diagnostic and surgical promptness are recommended.
