Sub mitral left ventricular aneurysm—Our experience

Objective Submitral left ventricular aneurysm is a rare anomaly which occurs most commonly among the black population. We would like to share our experience of 3 cases that we treated successfully by surgery at our institute. Methods From January 2001 to December 2010, 3 patients of submitral left ventricular aneurysm were treated at our institute. Age ranged from 25 to 30 years. There were 2 male subjects and 1 female subject. Two patients had moderate mitral regurgitation and one patient had severe mitral regurgitation. One patient had aneurysm with multiple necks. Diagnosis was made by echocardiography and was confirmed by angiography in all cases. In 2 cases aneurysm was excised and annulus was resuspended with interrupted sutures and in one case mitral valve was repaired with annuloplasty ring. Results All patients were discharged in stable condition. There was no early or late mortality. Follow up was done at 3 months and 3 years. Early follow up showed severe mitral regurgitation in one case and residual aneurysm cavity in one case. One case in which annuloplasty ring was used had no mitral regurgitation or residual aneurysm cavity. Conclusion Submitral left ventricular aneurysm is a rare cardiac lesion. Diagnosis can be done by echocardiography. Surgery is the treatment of choice and careful closure of all the necks of aneurysm and use of mitral annuloplasty ring is preferable. This can reduce recurrence of the post-operative mitral regurgitation and avoids the residual aneurysm cavity.
