Pulmonary artery aneurysm (PAA) may be associated with congenital shunt disease such as patent ductus arteriosus, and its frequency and management are often controversial. We report successful surgical treatment of PAA following an operation for atrial septal defect (ASD). The patient was a 47-year-old woman who underwent closure of ASD at the age of 9. When she was investigated because of thyroid tumor, enlargement of her main pulmonary artery was pointed out and she was admitted to our hospital. Several examinations revealed a diagnosis of pulmonary valve insufficiency and 70mm PAA with dilatation extending to both proximal arteries. We performed replacements of pulmonary valve and pulmonary artery with a bioprosthetic valve and T-shaped graft. The patient is doing well 2 years after operation.

Retrograde cardioplegia is now an alternative or adjunctive method used worldwide as a cardiac protection during open heart surgery. However, its use involves some limitation. We operated on a patient suffering from aortic stenosis associated with PLSVC. During the operation on this patient for aortic valve replacement, retrograde infusion of cardioplegic solution could not be performed because the coronary sinus was excessively dilated and prevented the balloon from occluding it. Other anomalous lesion of the coronary sinus make the retrograde infusion of the cardioplegic solution difficult and these must always be kept in mind when cardioplegia is infused from the coronary sinus.
