Vascular complications after balloon aortic valvuloplasty in recent years: Incidence and comparison of two hemostatic devices.

OBJECTIVES: To define the incidence of vascular complications (VC) after balloon aortic valvuloplasty (BAV) in recent years, and to compare the performance of two vascular closure devices (VCD).

BACKGROUND: VC remain the most frequent drawback of BAV and are associated with adverse clinical outcomes.

METHODS: All BAV procedures performed at 2 high-volume centers over a 6-year period (n = 930) were collected in prospective registries and investigated to assess the incidence of Valve Academic Research Consortium-2 (VARC-2) defined VC. Incidence of life-threatening, major and minor bleeding was also assessed. In-hospital major adverse cardiac and cerebrovascular events (MACCE) rate (composite of in-hospital death, myocardial infarction, TIA/stroke, and life-threatening bleeding) as well as 30-day survival was compared between a suture-mediated closure system and a collagen plug hemostatic device.

RESULTS: A 9 Fr arterial sheath was used in most of the patients (84.1%). Vascular closure was obtained with the Angio-Seal in 643 patients (69.1%) and the ProGlide in 287 (30.9%). The overall incidence of major VC was 2.7%, and minor VC 6.6%, without significant differences between groups. The Angio-Seal group was associated with a higher rate of small hematomas (6.9% vs. 3.5%, P = 0.042), whilst blood transfusions were more frequent in the ProGlide group (6.6% vs. 3.5%, P = 0.034). Rates of in-hospital MACCE and 30-day survival were similar. Use of either VCD was not independently associated with major VC.

CONCLUSIONS: VC rate after BAV is fairly low in experienced centers without major differences between the 2 most used VCD.
