Systemic mechanical heart valve replacement in children under 16 years of age

Abstract

Mechanical valve prostheses are a valuable option for left-sided heart valve replacement in pediatric patients with good results. Operative mortality and the incidence of any valve-related events as endocarditis, reoperation, thromboembolism or anticoagulation related bleeding is acceptable.

Prevention and Treatment of Thrombosis in Pediatric and Congenital Heart Disease

“…280 Using a minimum of 5 years of follow-up as the inclusion criterion, there are 8 retrospective studies summarizing experience with 296 pediatric patients that assessed the risk of anticoagulation with warfarin or other VKAs for a mechanical valve in the systemic atrioventricular (mitral) valve position. [283][284][285][311][312][313][314][315] Aspirin and dipyridamole were used along with warfarin in 1 study that included 30 patients. 315 The target INR varied between 2.0 to 3.0 and 3.0 to 4.0.…”

Comparison of mechanical and biological prostheses when used to replace heart valves in children and adolescents with rheumatic fever

“…Overall mortality in our study was 8.2%, similar to that reported by other researchers. [13][14][15][16][17][18] All hospital deaths occurred in patients undergoing urgent surgery, being, therefore, in the fourth functional class, or requiring reoperation. Mortality was greater after implantation of mitral than aortic valves, as reported from experience in Saudi Arabia.…”
