Potential advantages of transmitral myectomy include a panoramic view of the septum and mitral subvalvular apparatus and the ability to simultaneously address mitral valve pathology. Consideration should be given to using the transmitral approach to septal myectomy as the preferred approach for the surgical treatment of hypertrophic cardiomyopathy.

ECMO can be used as a bridge to heart valve or septal defect surgery in severely decompensated patients. Through recovery of end-organ function, ECMO may allow surgical correction of structural heart disease in patients considered inoperable or convert a salvage situation to an elective operation.
