Leadless endocardial pacing may offer an alternative for delivering cardiac resynchronization therapy in patients with coronary sinus atresia.
Cardiac resynchronization therapy (CRT) has revolutionized the treatment of advanced heart failure. However, effective placement of a left ventricular (LV) pacing lead via the coronary venous system is subject to anatomical constraints.
Thomas et al. (Sat,) conducted a case report in Dilated cardiomyopathy with severe left ventricular impairment and coronary sinus atresia (n=1). WiCS-LV system (leadless endocardial pacing) was evaluated on QRS duration and clinical improvement. Implantation of the WiCS-LV leadless endocardial pacing system successfully delivered cardiac resynchronization therapy in a patient with coronary sinus atresia, reducing QRS duration by 23% at 1 month.
