Introduction: The outcomes of transfemoral (TF) compared with transapical (TA) access for transcatheter aortic valve replacement (TAVR) in diabetics are unknown. Methods: We queried the NIS database (2011–2014) to identify diabetics who underwent TAVR. We performed a propensity matching analysis comparing TF-TAVR versus TA-TAVR. Results: The analysis included 14.555 diabetics who underwent TAVR. After matching, in-hospital mortality was not different between TF-TAVR and TA-TAVR. (3.5 vs. 4.4%, p = 0.11). TF-TAVR was associated with lower rates of cardiogenic shock (2.7 vs. 4.7%, p = 0.02), use of mechanical circulatory support (2.0 vs. 2.9%, p = 0.03), acute renal failure (17.8 vs. 26.5%, p < 0.001), major bleeding (35.8 vs. 40.7%, p < 0.001) and respiratory complications (1.1 vs. 4.4%, p < 0.001) compared with TA-TAVR. However, TF-TAVR was associated with a higher rate of vascular complications (2.9 vs. 0.9%, p < 0.001), cardiac tamponade (0.5 vs. 0.0%, p < 0.001), complete heart block (10.8 vs. 7.7%, p < 0.001) and pacemaker insertion (11.8 vs. 8.3%, p < 0.001). There was no difference between both groups in acute stroke (1.8 vs. 2.2%, p = 0.39), hemodialysis (2.0 vs. 2.2%, p = 0.71), and ventricular arrhythmias (4.9 vs. 4.2%, p = 0.19). Notably, TF-TAVR was associated with higher mortality, acute stroke, AKI, hemodialysis, PCI, and respiratory complications in complicated diabetics compared with non-complicated diabetics. Conclusions: This observational analysis showed no difference in-hospital mortality between TF-TAVR and TA-TAVR among diabetic patients. Studies exploring the optimal access for TAVR among diabetics are recommended.
