Objective: A hybrid operation is a joint procedure involving the interventional cardiologist and the cardiac surgeon concomitantly to optimize surgical management for complex congenital heart disease. We analyzed the feasibility and efficacy of this procedure in 20 patients with congenital heart disease.
Methods: Data from 20 patients who underwent intraoperative hybrid procedures from March to October 2005 were analyzed. Two groups were identified: (1) Balloon valvuloplasty group: pulmonary atresia with intact ventricular septum in neonate (n = 3) and severe pulmonary stenosis in infants (n = 4); (2) Device closure group: atrial septum defects (ASD) in child (n = 7), adult ASD (n = 3) and multiple ventricular septum defect (VSD, n = 3). Pulmonary balloon dilation under the guidance of echocardiography together with modified Blalock-Taussig shunt procedure and PDA ligation were applied to patients in balloon valvuloplasty group. For ASD patients, the occluder was placed via right atria after opening the chest either with median sternotomy (4 case) or with submaxillary minimally invasive incision (6 cases), PDA ligation was performed in 1 patient and 2 coronary artery bypass surgeries were performed in 2 adult ASD patients complicating CHD. For multiple VSD, perimembranous VSD was closed surgically and muscular VSD closed by occluder via tricuspid valve approach under cardiopulmonary bypass.
Results: All operations were successful and 1 infant received another conventional valvuloplasty due to the pulmonary restenosis after initial balloon valvuloplasty and 1 patient's muscular VSD was closed by conventional procedure after unsuccessful device closure. No device-related complications were found during follow-up (1-6 months).
Conclusion: Our results showed that intraoperative hybrid procedure was feasible and effective in selected patients with congenital heart disease.
