Impact of active cancer disease on the outcome of patients undergoing transcatheter aortic valve replacement

Background Patients undergoing transcatheter aortic valve replacement (TAVR) are often characterized by risk factors not reflected in conventional risk scores. In this context, little is known about the outcome of patients suffering from an active cancer disease (ACD). The objective was to determine the prevalence, clinical characteristics, perioperative outcomes, and mortality of patients with ACD undergoing TAVR compared to those with a history of cancer (HCD) and controls without known tumor disease. Methods TAVR patients between 02/2006 and 09/2014 were stratified according to the presence of ACD, HCD, and control. All‐cause‐mortality at 1‐year was the primary end point. All end point definitions were subject to the Valve Academic Research Consortium II definitions. Results Overall, 1821 patients were included: 99 patients (5.4%) suffered from ACD and 251 patients (13.8%) had HCD. ACD was related to a solid organ or hematological source in 72.7% and 27.3%, respectively. Patients with ACD were more often male (P = 0.004) and had a lower logisticEuroScore I (P = 0.033). Overall rates of VARC‐II defined periprocedural myocardial infarction, stroke, bleeding, access‐site complications, and acute kidney injury were not different between groups. Thirty‐day mortality did not differ between patients with ACD, HCD, and controls (6.1% vs 4.4% vs 7.6%, P = 0.176). All‐cause 1‐year mortality was higher in patients with ACD compared HCD and controls (37.4% vs 16.4% vs 20.8%, P
