A 75 year old man presented with left upper lobe squamous cell carcinoma. Severe aortic stenosis has been discovered during preoperative assessment. In this situation, two therapeutic strategies are described: concomitant or two-staged procedures. The debate has not yet led to the conclusion on whether preferably performing one or the other. Furthermore, in an oncologic context, using cardiopulmonary bypass is still controversial. So, thoracic and cardiac surgeons jointly proposed to the patient a transcatheter aortic valve implantation followed, 72 h later, by lung cancer resection. This case report describes a way to treat both diseases avoiding cardiopulmonary bypass adverse effects and without delaying lung cancer treatment.
