The Yasui operation: A single institutional experience over 30 years.

Area of Science:

• Pediatric Cardiac Surgery
• Congenital Heart Disease
• Cardiovascular Surgery

Background:

• The Yasui operation is a surgical procedure for complex heart defects including ventricular septal defect with aortic atresia or interrupted aortic arch.
• Left ventricular outflow tract obstruction (LVOTO) is a known long-term complication.
• Understanding long-term outcomes is crucial for patient management.

Purpose of the Study:

• To report the institutional experience with the Yasui operation.
• To evaluate the long-term efficacy and safety of the Yasui procedure.
• To identify factors influencing outcomes and reoperations.

Main Methods:

• Retrospective review of patients undergoing the Yasui operation from 1989 to 2021.
• Analysis of patient demographics, diagnoses, and surgical details.
• Assessment of survival, reoperations, and echocardiographic findings.

Main Results:

• Ninety-two percent survival was observed at 5 years in 25 patients.
• Freedom from LVOTO reoperation was 91% at late follow-up.
• All patients maintained normal biventricular function, with 87% having less than mild LVOTO at 5 years.

Conclusions:

• The Yasui operation is associated with low morbidity and mortality.
• Midterm reoperation for LVOTO is uncommon, and ventricular function is preserved.
• The procedure is a viable option for selected patients with complex congenital heart disease.
