“…[4,[11][12][13][14][20][21][22][23]37,38] Whether reoperation is more hazardous than strokes and hemorrhage, longterm valve-related mortality may be the most important criterion for comparison and literature is divided on the recommendation in young rheumatics. [6,[42][43][44][45][46][47] In our previous propensity matched investigation on 466 consecutive patients undergoing either bioprosthetic MVR (n= 233) or mechanical MVR (n=233), we compared 22year composites of valverelated reoperation, obesity, and mortality in young rheumatics aged less than 45 years. At a median follow up of 136 months (IQR: , our reoperation rate was 17.6% for mechanical prostheses and 13.6% in bioprosthetic arm, while reoperation for structural valve deterioration was associated with 0.27 times lower risk of cumulative mortality than reoperation for thrombosed mechanical processes (p<0.001).…”

“…[76,77] Our experience with valve thrombosis supports the findings of other series, including single valve replacement; it is a life threatening complication with a 50% mortality rate and is due to inadequate anticoagulation. [23,37,38,45] The inclusion of sudden death in the valve-related deaths remain controversial. Two recent autopsy studies have questioned the valve of Death.…”

Background and Aim: We compared 23-year composites of valve-related reoperation, morbidity, and mortality following combined mitral and aortic mechanical and bioprostheses in young rheumatics aged <45years. Methods: Retrospective comparative analysis of valve-related reoperations and survival data were performed from 498 consecutive propensity matched patients undergoing either bioprosthetic MVR (Group I, n=249) or mechanical MVR (Group II, n=249) between 1998 and 2022. Results: The median age was 33 (IQR: 27-40) and 33 (IQR: 28-39) years for Group I and II respectively. The median follow-up was 134 months (IQR: 99.5-178.5) with 5281.8 patient-years data in both biological and mechanical arm. Bioprosthetic arm exhibited lesser cumulative mortality (3.6% vs 4.8%, SMD= -0.18, p=0.01). Hazard regression for mortality included (HR, 95% CI) included preoperative CHF on inotropes and ventilator 9.84 (4.54, 18.64), p<0.001, renal failure requiring peritoneal/hemodialysis 11.64, (6.57, 20.64), p<0.001, atrial fibrillation 3.83 (1.63, 8.98), p<0.002, reoperation for thrombosed mechanical and degenerated bioprostheses 5.38, (3.09, 9.35), p<0.001, previous operation 3.53, (1.93, 6.45), p<0.001, poor left ventricular function 4.25, (2.29, 7.88), p<0.001, prolonged aortic clamp time 3.84, (2.19, 6.78), p<0.001, and prolonged CPB time 2.69, (1.84, 8.68), p<0.001. Propensity score matching did not exhibit any difference in reoperation between two groups (Group I vs Group II: 13.6% vs 17.6%, SMD= -0.110, p=0.21). At a median follow-up of 134 months (IQR: 99.5-178.5) months, actuarial survival was 92.3%±0.02% (group I vs 96.6%+0.01%) and there was no difference between the groups (p=0.90). Conclusions: Bioprostheses are an acceptable alternative to mechanical prostheses in young rheumatics aged <45 years undergoing mitral and aortic valve replacements unwilling for mechanical valve, redo surgeries, life-long anticoagulation, and those desirous of pregnancy.

Transesophageal echocardiography (TEE) has become increasingly important in the assessment of mitral valve prosthetic dysfunction. We report on three patients who developed medically refractory hemolytic anemia after St. Jude mitral valve replacement secondary to perivalvular mitral prosthetic regurgitation. Two of the three cases had corrective surgical intervention that resolved the hemolytic process. Careful transesophageal echocardiographic evaluations of the perivalvular area proved diagnostic and resulted in appropriate management decisions.
