Abstract

INTRODUCTION: Transapical transcatheter aortic valve replacement (TAVR) is associated with increased morbidity compared with endovascular TAVR. We sought to compare the differences in clinical outcomes between endovascular and transapical TAVR approaches utilizing a propensity score model.

METHODS: Patients undergoing TAVR (International Classification of Diseases, Ninth Revision, Clinical Modification codes 35.05 and 35.06) between January 2011 and November 2014 were identified in the Nationwide Readmissions Database, and a propensity score-matched analysis was performed comparing transapical versus endovascular approach. The primary outcome of interest was in-hospital mortality and 30-day all-cause readmission. We also evaluated trends in use of TAVR over the years.

RESULTS: We identified 28,302 endovascular TAVR and 7967 transapical TAVR performed during the study period. The propensity score-matching algorithm yielded 7879 well-matched patients in each group. The in-hospital mortality rates were significantly lower in endovascular TAVR compared with transapical TAVR (1.7% vs 6.7%; OR, 0.24; 95% CI, 0.17- 0.35; P < 0.001). The 30-day readmission rate was lower in endovascular TAVR (14.4% vs 16.8%; OR, 0.83; 95% CI, 0.70-0.98; P = 0.036). Use of TAVR increased from 585 (74% endovascular TAVR) in 2011 to 16,801 in 2014 (82.8% endovascular TAVR).

CONCLUSIONS: Endovascular TAVR is associated with significantly lower in-patient mortality and lower readmission rate when compared with transapical TAVR. Heart failure remains the most common cause for readmission after TAVR regardless of approach.
