BACKGROUND:The ideal aortic valve substitute in young and middle-aged adults remains unknown. We sought to compare the long-term outcomes of patients undergoing the Ross procedure and those receiving a mechanical aortic valve replacement (AVR). METHODS:From 1990 to 2014, 258 patients underwent a Ross procedure and 1444 had a mechanical AVR at a single institution. Patients were matched into 208 pairs through the use of a propensity score. Mean age was 37.2±10.2 years, and 63% were male. Mean follow-up was 14.2±6.5 years. RESULTS:Overall survival was equivalent (Ross versus AVR: hazard ratio, 0.91, 95% confidence interval, 0.38-2.16; P=0.83), although freedom from cardiac-and valve-related mortality was improved in the Ross group (Ross versus AVR: hazard ratio, 0.22; 95% confidence interval, 0.034-0.86; P=0.03). Freedom from reintervention was equivalent after both procedures (Ross versus AVR: hazard ratio, 1.86; 95% confidence interval, 0. 76-4.94; P=0.18). Long-term freedom from stroke or major bleeding was superior after the Ross procedure (Ross versus AVR: hazard ratio, 0.09; 95% confidence interval, 0.02-0.31; P<0.001).CONCLUSIONS: Long-term survival and freedom from reintervention were comparable between the Ross procedure and mechanical AVR. However, the Ross procedure was associated with improved freedom from cardiacand valve-related mortality and a significant reduction in the incidence of stroke and major bleeding. In specialized centers, the Ross procedure represents an excellent option and should be considered for young and middle-aged adults undergoing AVR. long-term Outcomes of the ross Procedure Versus Mechanical aortic Valve replacementPropensity-Matched cohort study © 2016 American Heart Association, Inc.Key Words: aortic valve ◼ propensity score ◼ surgery ◼ treatment outcome ORIGINAL RESEARCH ARTICLE 577 Y oung and middle-aged adults with diseased aortic valves constitute a challenging population. Because of their longer anticipated life expectancy, these patients present a higher cumulative lifetime risk of prosthesis-related complications. The ideal aortic valve substitute in this patient population should allow improved survival, avoidance of reoperation and prosthesis-related complications, and maintenance of an active lifestyle with a good quality of life.As a result of their proven durability and ease of implantation, mechanical prostheses have long been the most frequently used option for aortic valve replacement (AVR) in young and middle-aged adults. However, recent reports suggest an excess in long-term mortality in young patients who undergo mechanical AVR compared with the age-and sex-matched general population.1,2 In addition, for female patients of childbearing age, mechanical prostheses are associated with an increased risk of thromboembolic events and warfarin-associated fetal malformations. 3,4 The Ross procedure (pulmonary autograft replacement) alleviates the need for lifelong anticoagulation. It allows the replacement of the diseased aortic valve with a living substitute, 5 th...

More than 50 years have passed since the first successful heart valve replacement. Since then, many types of mechanical prostheses have been introduced. The prosthesis choice for the replacement of an affected valve is a major concern in valvular surgery. The introduction of a new heart valve prosthesis requires accurate data collection and data processing for a long follow-up period. In present article we sought to compare modern commercial available bileaflet foreign mechanical valve prosthesis for their long follow-up with Russian mechanical valve for aortic and mitral valve replacement.

ImportanceAggregated data and long-term follow-up in national health data registers offer the opportunity to compare the performance of mechanical aortic prostheses within the same population.ObjectiveTo investigate the clinical performance of mechanical aortic valve prostheses.Design, Setting, and ParticipantsThis nationwide cohort study included all 5224 patients who underwent primary mechanical aortic valve replacement in Sweden between January 1, 2003, and December 31, 2018. Statistical analysis was performed between May and September 2023.ExposuresSurgical aortic valve replacement with the On-X, Carbomedics, Bicarbon, Standard, Regent, Open Pivot, Masters, or Advantage valve models.Main Outcomes and MeasuresThe primary outcome was all-cause mortality, and secondary outcomes were reintervention, heart failure, major bleeding, stroke, and embolic events. Regression standardization was used to account for baseline differences.ResultsOverall, 5224 patients (mean [SD] age, 56.8 [11.7] years; 3908 men [74.8%]) were included. Total follow-up time was 43 982 person-years (mean [SD], 8.4 [4.6] years; maximum, 17.2 years). After regression standardization, there was a significant difference in 10-year mortality between the Carbomedics model group (17%; 95% CI, 15%-18%), Regent model group (17%; 95% CI, 13%-20%), and Standard model group (17%; 95% CI, 14%-19%) compared with the Bicarbon model group (27%; 95% CI, 21%-34%).Conclusions and RelevanceIn this cohort study of mechanical valve surgical aortic replacement outcomes in Sweden, the rate of all-cause mortality was higher in the Bicarbon group than in the Carbomedics, Regent, and Standard model groups. These findings warrant further research on the long-term clinical performance of the Bicarbon valve.
