Ching-Hui Shen, Chung-Chi Wang, Hsien-Te Fang and Ming-Chih Lin From Atretic to Perforated: A Closer View of Pulmonary Atresia Echocardiography 31
A 7-day-old male infant with membranous pulmonary atresia and intact ventricular septum (PA/IVS) underwent hybrid pulmonary valvotomy. The procedure was performed under the guidance of intra-operative epicardial ultrasonography. After puncturing the atretic pulmonary valve, a 6 mm Wanda balloon catheter was inflated to dilate the atretic valve. Adequate valve movement with antegrade flow was confirmed using real time epicardial echocardiography. Intra-operative epicardial ultrasonography is an effective guiding tool for PA/IVS during hybrid procedures. Epicardial echocardiography imaging provides clear images with excellent quality, helps guide the hybrid surgery, and prevents the need for fluoroscopy.
