Surgery for rheumatic lesions of the cardiac valves in the young

Abstract

SummaryAlthough declining in the so-called “first world,” surgery for rheumatic valvar lesions in patients less than 16 years of age is still a challenging problem in lesser developed countries. From 1970 to 1990, we operated upon and followed-up 136 children (less than 16 years) with different valvar lesions, performing various surgical procedures. The mitral valve was most frequently affected (52.9%) followed by multiple valvar disease (39.7%) and aortic (7.3%) involvement. The operations performed were valvoplasties (67), valvar replacement (49), and combined procedures (20). Hospital mortality for the overall group was 10.2%. There were 71 reinterventions in the follow-up of 20 years. Actuarial survival was 60.3% including hospital mortality. The event-free actuarial survival showed that 91% had at least one major event which required reoperation or hospital treatment, or else invasive cardiac procedures. We conclude that rheumatic valvar disease is still a challenging problem in our country, and that the severity of the illness is directly related to the younger age patients. In spite of reasonable long-term survival, very few patients had an uneventful follow-up after surgery.
