Background Intraprocedural coronary angiography (CA) is recommended in patients undergoing ablation in aortic cusps to assess the relation of catheter tip and coronary ostia. In this report, we aimed to compare selective coronary angiography (SCA) through the contact force (CF)-sensing radiofrequency catheter with conventional coronary angiography (CCA) to guide ablation of premature ventricular contractions (PVC). Methods This was a retrospective observational cohort study of prospectively collected data of 87 consecutive patients undergoing PVC ablation at a single institution between February 2016 and June 2021. Forty-six patients (53%) underwent SCA and forty-one patients (47%) underwent CCA. Data were consecutively collected case-by-case and entered into a computerized database. Procedural characteristics, complications, and clinical outcomes were compared between the SCA and CCA groups. Results Successful ablation was achieved in seventy-seven (89%) patients. Total procedure and fluoroscopy time and radiation dose were significantly lower in SCA group (93 +/- 22 min vs 102 +/- 20 min, p = 0.042; 12 +/- 3 min vs 14 +/- 4 min, p = 0.030; 3292 +/- 1221 mu Gy m(2) vs 3880 +/- 1229 mu Gy m(2), p = 0.028, respectively). Median ambulation time was significantly longer in CCA group (6.8 +/- 1 h vs 17.8 +/- 1.8 h, p = 0.006). Conclusions Selective coronary angiography through the CF-sensing ablation catheter to assess the relation between the ablation site and the coronary ostia is feasible and safe. This technique precludes the requirement of an additional arterial access and decreases the total procedure and fluoroscopy time and radiation dose.
