Apicoaortic bypass (AAB), or apicoaortic conduit insertion, is a conventional surgical method that has been regaining attention due to the aging population and the increasing number of repeat surgeries. The indication for the procedure has been extended as an alternative for aortic stenosis when the usual sternotomy or aortic clamping is considered to be difficult, e.g., in patients with severe calcification of the ascending aorta (porcelain aorta), or in patients with a patent coronary artery bypass graft located adjacent to the posterior surface of the sternum. Herein, we report our recent anesthetic management of three patients undergoing AAB. Once the apicoaortic conduit is inserted, blood from the left ventricle is ejected via two routes, the narrowed native aortic valve and the apicoaortic conduit. Thus, it is necessary to elucidate any change in blood flow after the withdrawal of the extracorporeal circulation, by using intraoperative transesophageal echocardiography. Furthermore, if a rigid apical connector is not used, anastomosis of the cardiac apex and conduit is conducted under ventricular fibrillation without the infusion of cardioplegic solution; thus, patients are deemed likely to suffer increased myocardial damage. As a rigid apical connector was not used in the three present patients, the administraction of adequate catecholamines was needed for the withdrawal of the extracorporeal circulation. In addition, because those undergoing AAB often have extremely poor cardiac reserve preoperatively owing to the administration of adequate catecholamines was needed for the withdrawal of the extracorporeal circulation. In the three present patients, anesthetic management was successful, and there were no intraoperative or immediate postoperative complications.
