Outcomes for mitral valve replacement (MVR) in the pediatric population are generally reported as poor, particularly in patients less than 2 years old. We compared long-term morbidity and mortality associated with MVR between patients less than 2 years old and patients 2 to 18 years old.


We evaluated pediatric patients undergoing MVR from March 1990 to November 2007 at our institution. Morbidity and mortality was compared between patients less than 2 years and patients 2 to 18 years old. Primary endpoints measured were postoperative survival, long-term survival, reoperation, cerebrovascular accident or transient ischemic attack, and significant bleeding events.


Forty-five patients underwent 54 MVRs. Median age was 3.1 years; 18 patients were under 2 years. Median follow-up time was 5.4 years. There was no statistically significant difference between long-term or short-term survival between the two age groups, with 30-day survival of 89% (younger patients) versus 100% (older patients), and 10-year survival of 82% (younger patients) versus 85% (older patients). Freedom from reoperation for the younger age group was 40% at 10 years versus 96% for the older patients, p = 0.003.


In our population, there was no statistically significant difference in survival between patients less than 2 years and patients 2 to 18 years. In children undergoing MVR, age less than 2 years remains a risk factor for reoperation but not for mortality.
