Abstract

Background: The most common complications of electrophysiology (EP) procedures are related to vascular access.
Objective: Our study aimed to compare the ultrasound (US)-guided (Group 1) vs. palpation-based (Group 2) technique for femoral venous access in AF ablation procedures.
Methods: Between January 2018 and November 2019, 355 patients undergoing pulmonary vein isolation (PVI) on uninterrupted anticoagulant treatment were included. They were allocated to Group 1 or 2 based on which of the two procedure rooms their procedure was scheduled in, with only one of the rooms equipped with an US machine including an 8 MHz linear transducer. Major and minor complications and the rate of prolonged hospitalization were compared in the two groups. Major vascular complication was defined as groin hematoma, arteriovenous fistula, or pseudoaneurysm. Hematoma was considered as a major vascular complication if it met type 2 or higher Bleeding Academic Research Consortium (BARC) criteria (requiring nonsurgical, medical intervention by a health care professional; leading to hospitalization or increased level of care, or prompting evacuation).
Results: Of the 355 patients 105 were allocated to Group 1 and 250 included in Group 2. Compared to the standard technique, the use of US significantly reduced both major (from 5.60% to 0.95%, p=0.047) and minor (from 6.40% to 0.95%, p=0.029) vascular complications. The absolute risk reduction (ARR) of minor/major vascular complications was 10.10% equated to a relative risk reduction (RRR) of 84.13%, and a number needed to treat (NNT) of 10 to prevent one bleeding event. No difference was found for the rate of prolonged hospitalization (5.04% vs. 0.95%, p=0.119).
Conclusion: With the use of US for the femoral vein puncture in patients undergoing PVI procedure the rate of both major and minor vascular complications were lower.
