Quadricuspid pulmonary valve stenosis treated by transcatheter pulmonary valvuloplasty with inoue balloon catheter.

Abstract

The quadricuspid pulmonary valve is a relatively common congenital anomaly which is rarely complicated clinically and also tends to be under-diagnosed. The following case report shows a 62-year-old man with exertional dyspnea due to quadricuspid pulmonary valve stenosis that was diagnosed by using electrocardiography-gated multiple detector computed tomography. He was then treated effectively by transcatheter balloon pulmonary valvuloplasty using an Inoue balloon catheter. <Learning Objective: The quadricuspid pulmonary valve is a congenital anomaly which is rarely complicated clinically and tends to be under-diagnosed. Electrocardiography-gated multiple detector computed tomography is a useful imaging modality for diagnosing the quadricusid pulmonary valve. Transcatheter pulmonary valvuloplasty with an Inoue balloon catheter was effective for treating quadricuspid pulmonary valve stenosis.>.
