<jats:title>Background</jats:title>
<jats:p>Vascular complications are a common occurrence during atrial fibrillation ablation. Observational studies indicate that the utilization of ultrasound (US)-guided puncture may decrease the incidence of vascular complications; however, its routine use is not established in many centres.</jats:p>

<jats:title>Methods</jats:title>
<jats:p>Patients undergoing catheter ablation for atrial fibrillation were included sequentially. All patients receiving US-guided punctures were prospectively enrolled (US group), while patients who underwent the procedure with standard puncture technique served as control group (No-US group). Periprocedural vascular complications requiring intervention within 30 days of the procedure were defined as the primary endpoint.</jats:p>

<jats:title>Results</jats:title>
<jats:p>A total of 599 patients (average age: 69 ± 11 years, 62.9% male) were analysed. The incidence of vascular complications was lower with the US-guided puncture than with the anatomic landmark-guided puncture (14/299 [4.7%] vs. 27/300 [9%], <jats:italic>p</jats:italic> = 0.036). The US-guided vascular access significantly reduced the rate of false aneurysms (3/299 [1%] vs. 12/300 [4%], <jats:italic>p</jats:italic> = 0.019). In addition, the occurrence of arteriovenous fistula (2/299 [0.7%] vs. 4/300 [1.3%], <jats:italic>p</jats:italic> = 0.686) and haematoma requiring treatment (9/299 [3%] vs. 11/300 [3.7%], <jats:italic>p</jats:italic> = 0.655) were also lower in the US group. US-guided puncture did not prolong the procedure time (mean procedure time: 57.48 ± 24.47 min vs. 56.09 ± 23.36 min, <jats:italic>p</jats:italic> = 0.478). Multivariate regression analysis identified female gender (OR 2.079, CI 95% 1.096–3.945, <jats:italic>p</jats:italic> = 0.025) and conventional vascular access (OR 2.079, CI 95% 1.025–3.908, <jats:italic>p</jats:italic> = 0.042) as predictors of vascular complications.</jats:p>

<jats:title>Conclusions</jats:title>
<jats:p>The implementation of US-guided vascular access for left atrial catheter ablation resulted in a significant decrease of the overall vascular complication rate.</jats:p>
