AIMS: To assess outcomes of TAVR as a rescue therapy in patients with cardiogenic shock due to acutely decompensated aortic stenosis. METHODS AND RESULTS: Of 771 high-risk patients who underwent TAVR, 27 (3.5%; 78±9 years; 12 men) were treated emergently due to acutely decompensated aortic stenosis with cardiogenic shock. SAPIEN and CoreValve prostheses were implanted in 11 and 16 patients, respectively: the transfemoral access route was used in 25. Three patients died within 72 hours of successful valve deployment, and a further six died within a month, giving a 30-day mortality of 33.3%, which was significantly higher than in electively treated patients (7.7%, p<0.0001). Univariate predictors of 30-day mortality in cardiogenic-shock patients were baseline cardiac output <3.0 l/min, reduced cardiac power index, impaired renal function, and mechanical ventilation, as well as severe acute kidney injury after TAVR. Estimated one-year survival was 59.3% in emergently and 82.7% in electively treated patients (p=0.0009). However, 30-day landmark analysis showed no difference in cumulative survival between TAVR modalities. In cardiogenic-shock patients without concomitant reduced cardiac output and impaired renal function at baseline (n=22), estimated one-year survival was 72.7%. CONCLUSIONS: TAVR should be considered a reasonable rescue therapy in patients with cardiogenic shock secondary to decompensated aortic stenosis.
