Background: Vascular complications still represent an important issue after transcatheter aortic valve implantation (TAVI). Aims: The aim of this study was to evaluate the effectiveness of upfront use of an adjunctive Angio-Seal (AS) plug-based system on top of suture-based devices (SBDs) for endovascular haemostasis after trans-femoral (TF) TAVI. Methods: From January 2019 to April 2020, 332 consecutive patients with preprocedural computed tomography angiography (CTA) assessment underwent fully percutaneous TF-TAVI. The primary outcomes were 30-day major vascular complications and major or life-threatening (LT) bleeding due to endovascu-lar closure system failure. A total of 246 TF-TAVI patients (123 pairs), undergoing either isolated SBD or SBD+AS, were matched using the propensity-score method. Results: At 30 days, patients receiving SBD+AS had lower rates of major/LT bleeding (1.6% vs 8.9%, odds ratio [OR] 0.17, 95% confidence interval [CI]: 0.04-0.78; p<0.01) and major vascular complications (1.6% vs 8.9%, OR 0.17, 95% CI: 0.04-0.78; p<0.01). In addition, the use of SBD+AS was associated with a sig-nificant cost saving related to the vascular event (mean difference -315.3 euro per patient, 95% CI: -566.4 euro to -64.1 euro ; p=0.01), and a higher probability of next-day discharge (NDD) after TAVI (30.9% vs 16.3%, OR 2.30, 95% CI: 1.25-4.25; p<0.01). No difference in all-cause 30-day mortality was observed (3.3% vs 1.6% for SBD and SBD+AS groups, respectively, OR 0.49, 95% CI: 0.09-2.74; p=0.41). Conclusions: An upfront combined strategy with an additional AS plug-based device on top of SBDs was shown to reduce major vascular complications and major/LT bleeding due to closure system failure after TF-TAVI. This approach was associated with a cost saving and with a higher probability of NDD compared to the use of isolated SBD.

Abstract

Background: Vascular complications still represent an important issue after transcatheter aortic valve implantation (TAVI). Aims: The aim of this study was to evaluate the effectiveness of upfront use of an adjunctive Angio-Seal (AS) plug-based system on top of suture-based devices (SBDs) for endovascular haemostasis after trans-femoral (TF) TAVI. Methods: From January 2019 to April 2020, 332 consecutive patients with preprocedural computed tomography angiography (CTA) assessment underwent fully percutaneous TF-TAVI. The primary outcomes were 30-day major vascular complications and major or life-threatening (LT) bleeding due to endovascu-lar closure system failure. A total of 246 TF-TAVI patients (123 pairs), undergoing either isolated SBD or SBD+AS, were matched using the propensity-score method. Results: At 30 days, patients receiving SBD+AS had lower rates of major/LT bleeding (1.6% vs 8.9%, odds ratio [OR] 0.17, 95% confidence interval [CI]: 0.04-0.78; p<0.01) and major vascular complications (1.6% vs 8.9%, OR 0.17, 95% CI: 0.04-0.78; p<0.01). In addition, the use of SBD+AS was associated with a sig-nificant cost saving related to the vascular event (mean difference -315.3 euro per patient, 95% CI: -566.4 euro to -64.1 euro ; p=0.01), and a higher probability of next-day discharge (NDD) after TAVI (30.9% vs 16.3%, OR 2.30, 95% CI: 1.25-4.25; p<0.01).
