Spasm cases and the spatial relationship and distance between the catheter tip and coronary arteries. (A) The angiography showed 90% spasm in left circumflex artery (LCX) #12. The catheter was positioned directly over the coronary artery. (B) Pulsed-field ablation (PFA) resulted in 90% LCX #11 spasm. The small window showed that the catheter crossed the artery at a distance of approximately 1 mm. (C) The catheter was parallel to the artery over a relatively long distance. (D) Left descending artery #6 developed 99% spasm by PFA from right ventricular outflow tract. (E) Intracardiac echography showed that the catheter was close to the artery during PFA. LAD, left anterior descending artery.
