A 35‐year‐old patient underwent permanent pacemaker implantation because of symptomatic sinus bradycardia. During the procedure, persistent left superior vena cava was found. The ventricular lead crossed the tricuspid valve only after curving the stylet to form a loop in the right atrium (RA); subsequently, the curved stylet was changed to a straight one and the lead was positioned and screwed into the right ventricular apex. The atrial lead positioning was possible when the stylet was slightly curved and the lead could reach the anterior wall of the RA. At 18 months, a follow‐up revealed normal pacemaker function and stable lead position.
