Clinical surgical experience of congenital submitral left ventricular aneurysm.

Submitral left ventricular aneurysm is a rare cardiac pathology, occurring almost exclusively in black African patients. Two cases treated in our institute are reported in the present report. One is a 10-year-old boy with submitral aneurysm and mitral regurgitation, who underwent mitral valve repair and exclusion of the aneurysm with a left atrial approach. He underwent a second operation due to mitral regurgitation caused by retraction of the mitral apparatus by the patch scarring. The other case is a 39-year-old male patient who presented with ventricular tachycardia. The aneurysm was excluded by a Dacron patch from outside the left ventricle in addition to cryoablation on the endocardium of the aneurysm. Both patients recovered well after the operation. The present report presents two cases of this rare disease with different surgical approaches.
