Doubly Committed Subarterial Ventricular Septal Defects Closure Using Minimal Mid-Partial Sternotomy.

BACKGROUND: Repair of doubly committed subarterial ventricular septal defects (DCVSD) via a minimal mid-partial sternotomy has not been reported. We aimed to evaluate the feasibility and safety of this procedure.

METHODS: We retrospectively reviewed all patients with a clinical diagnosis of DCVSD and underwent repair via minimal mid-partial sternotomy at our institution. Patient characteristics, perioperative, and follow-up data were collected.

RESULTS: A total of 13 patients who underwent minimal mid-partial sternotomy DCVSD repair were analyzed. Postoperative echocardiogram revealed that no patient had the residual shunt. No patient reported adverse event during postoperative course. There was no perioperative or late death during follow-ups. All patients were satisfied with the inconspicuous scar.

CONCLUSIONS: Minimal mid-partial sternotomy is a safe and effective approach for DCVSD repair with satisfied treatment outcomes and cosmetic benefits.
