Fig. 1From: Biventricular repair of pulmonary atresia with intact ventricular septum and severely hypoplastic right ventricle: a case report of a minimum intervention surgical approachPreoperative right ventriculography showed that the end-diastolic volume was 22 % of normal and the Z-score of the tricuspid valve and pulmonary valve was −5.4 and −3.8, respectively. (a anterior, b lateral). c The distal end of a 3.5 mm polytetrafluoroethylene graft was attached to the main pulmonary artery (←) by end-to-side anastomosis. d The graft was attached tangentially to the left side of the ascending aorta by side-to-side anastomosis. e The proximal stump of the graft was closed, creating a funnel-shaped graft (funnel shunt) to avoid kinking.
