Two cases of lobectomy for lung cancer after transcatheter aortic valve implantation

Abstract

Abstract Background The age of patients with lung cancer is advancing, and the number of patients with lung cancer who have cardiac diseases is expected to increase. Recently, the rate of transcatheter aortic valve implantation (TAVI) has increased as treatment for aortic stenosis (AS). TAVI is minimally invasive compared with conventional aortic valve replacement. We herein report two patients with lung cancer who underwent lobectomy after TAVI for severe AS. Case presentation Two patients with AS and lung cancer were treated with two-stage surgery of TAVI followed by lobectomy. In patient 1 (77 years of age), conventional aortic valve replacement was considered to be risky because of his history of coronary artery disease and thoracic aortic aneurysm and his relatively high logistic euroSCORE. He underwent TAVI followed by right middle and lower lobectomy. In patient 2 (75 years of age), TAVI was chosen because the patient had poor ADL due to spinal canal stenosis and had taken immunosuppressant agents after a kidney transplantation. He underwent TAVI followed by right lower lobectomy. The postoperative course of the two patients was uneventful. Conclusions Two-stage surgery of TAVI and lung resection could be a viable option for patients with both lung cancer and severe AS, for whom conventional AVR by an open-heart operation is not indicated.
