Coronary Sinus Lead Placement in Patients With Coronary Sinus Ostial Atresia: An Innovative Approach

JACC Case Rep. 2021 Apr 21;3(4):614-618. doi: 10.1016/j.jaccas.2021.02.027. eCollection 2021 Apr.


This case series demonstrates 2 innovative approaches to successful coronary sinus lead placement in the setting of coronary sinus ostial atresia. Use of venous phase coronary angiography, a computed tomography scan with venous phase, or a left-sided upper extremity venogram may help reveal a variant anatomy and guide tool selection. (Level of Difficulty: Advanced.).
