title: Percutaneous balloon valvuloplasty of both pulmonary and aortic valves in a neonate with pulmonary atresia and critical aortic stenosis.
abstract: We report a case of hydrops fetalis originating from critical aortic stenosis and pulmonary atresia with intact ventricular septum that was diagnosed in utero by echocardiography. We performed a percutaneous balloon valvuloplasty of the bilateral semilunar valves on the 2nd day after birth. We used a stiff-ended guidewire to perforate the pulmonary valve. After valvuloplasty, the aortic valve pressure gradient decreased from 55 to 25 mmHg. The procedure was successful, and the patient's heart condition improved.
