Complexity of some congenital heart diseases sometimes necessitates a combination of interventional procedures and surgery, amongst which intraoperative stent implantation is one of the most common. We herein report a successful hybrid procedure in a cyanotic adult patient who had undergone no procedure in childhood. The patient was a 24-year-old cyanotic male (oxygen saturation in the room air was 65%) who presented with dyspnea. According to echocardiography, catheterization, and cardiac magnetic resonance imaging data, the patient was amenable to the Fontan surgery. However, because of significant left pulmonary stenosis and his age, he first underwent a hybrid procedure (Glenn shunt and left pulmonary artery [LPA] stenting). After the procedure, oxygen saturation rose to 83%. At six months' follow-up of the patient, exercise capacity and cyanosis had improved significantly, with O2 saturation having reached near 85% by pulse oximetry.
