ABSTRACT
BACKGROUND:
Transfemoral access is the most common approach for transcatheter aortic valve replacement (TAVR). However, a subset of patients require alternative access. This study describes the evolution and outcomes of alternative-access TAVR at Cleveland Clinic.METHODS:
From January 2006 to January 2019, 2446 patients underwent TAVR, 414 (17%) through alternative access (247 transapical, 95 transaortic, 56 transaxillary, 2 transcarotid, 10 transiliac, 4 transcaval). Patients undergoing alternative-access TAVR had high preoperative risk. Propensity-matched comparisons were targeted at comparing transfemoral versus transaxillary approaches since 2012.RESULTS:
Over time, the favored alternative-access approach shifted from transapical and transaortic to transaxillary. Pacemaker requirement was similar for alternative-access and transfemoral approaches. Compared with transfemoral access, major vascular injuries were higher in the alternative-access group (12 [2.9%] vs 27 [1.3%], P = .02), but minor vascular injuries were lower (13 [3.1%] vs 198 [9.8%], P < .0001). Non-risk-adjusted 5-year survival was lower in the alternative-access group (45% vs 59%). Compared with intrathoracic approaches (transapical and transaortic), transaxillary access was associated with fewer blood transfusions (12 [21%] vs 176 [51%], P < .0001), less prolonged ventilation (1 [1.8%] vs 38 [11%], P = .03), and shorter length of stay (median, 5 vs 7.5 days, P < .0001). Survival and major morbidity were similar in matched comparisons of the transfemoral and transaxillary approaches. No brachial plexus injuries occurred with transaxillary access.CONCLUSIONS:
The transaxillary approach has emerged as our preferred alternative-access strategy for TAVR. It is associated with superior operative outcomes compared with transthoracic approaches, and results are comparable with those of the transfemoral approach.
