Background:
We report a surgical series of submitral aneurysm in children.
Methods:
Between March 2011 and December 2015, eight consecutive patients less than 18 years old with submitral aneurysm underwent surgical correction.
Results:
Six patients were female, the mean age was 7 ± 3.8 years old, and mean weight was 21.4 kg. Six patients were in NYHA functional class III or IV. Six patients underwent repair via a transatrial approach, another with a transatrial combined with transaneurysmal approach, and another with a transventricular approach. There were no in-hospital deaths but one 30-day mortality. One patient required reoperation. Two patients required mitral valve replacement. At discharge, one patient had severe and another had moderate mitral regurgitation. The mean follow-up time was 26.4 months and five patients were alive. No reintervention was required.
Conclusions:
Submitral aneurysm is not restricted to adults. Heart failure is the commonest clinical presentation in the pediatric age. The transatrial approach is feasible, safe, and associated with good short-term results. The mitral valve can be preserved in the majority of cases.
