Transapical myectomy through a left ventricular incision provides an alternative approach for septal excision in hypertrophic cardiomyopathy when transaortic exposure is inadequate.

May be considered for septal excision in select HCM cases; leaves open need for comparative safety and outcome data.
Exposure of the basal and midventricular septum through the aortic root to relieve obstruction in hypertrophic cardiomyopathy can be challenging. Inadequate myectomy will lead to persistent symptoms and disability. Adequate exposure of the obstructive left ventricular septum is of paramount importance in primary and redo myectomy. In selected patients, either at primary myectomy or at redo myectomy, septal excision can be approached through a left ventricular transapical incision when transaortic exposure is inadequate.

Quintana et al. (2015) studied Hypertrophic cardiomyopathy. Transapical myectomy was evaluated. Transapical myectomy through a left ventricular incision provides an alternative approach for septal excision in hypertrophic cardiomyopathy when transaortic exposure is inadequate.
