Abstract

Abstract A 5-month-old girl, weighing 5.3 kg, diagnosed ALCAPA underwent emergency surgery. The left coronary artery (LCA) originated from the posterior pulmonary artery (PA), and the left main trunk (LMT) was very short (1.5 mm), with moderate level of mitral valve regurgitation (MR). The distance from the origin to the pulmonary valve (Pv) was also short. A free extension conduit was created using adjacent sinus Valsalva flaps and implanted in the ascending aorta to avoid distortion of the coronary artery and the Pv.

Abstract

A 9-month-old infant developed pulmonary stenosis (PS) after an arterial switch operation for transposition of the great arteries, accompanied by a Shaher Type 4 coronary anatomy. As the right coronary artery (RCA) ran across the anterior side of the right ventricle (RV), atrioventricular (AV) groove patch plasty was performed to relieve PS. The distance between the RCA and tricuspid valve was confirmed by preoperative-computed tomography. The AV groove was carefully incised, ensuring the position of the tricuspid valve, and maintaining a distance of 3 mm from the tricuspid annulus to avoid approaching the RCA. While suturing the monocuspid valve patch, only the endocardial side of the RV was sutured, and RCA injury was prevented. Thus, especially in patients
