Key result
Implantation of a pacing lead in the coronary sinus for cardiac resynchronisation therapy is feasible despite the presence of a remodeling device in the coronary sinus.
Why the study?
Is implantation of a pacing lead in the coronary sinus for CRT feasible in a patient with a pre-existing remodeling device in the coronary sinus?

Is implantation of a pacing lead in the coronary sinus for CRT feasible in a patient with a pre-existing remodeling device in the coronary sinus?
Demonstrates the feasibility of CRT pacing lead implantation in the coronary sinus even when a percutaneous mitral annuloplasty remodeling device is already present.
May support CRT lead placement after coronary sinus remodeling in select cases; leaves open safety, efficacy, and generalizability.
Percutaneous approaches to reduce mitral regurgitation in ischemic cardiomyopathy have stirred interest recently. Patients with ischemic cardiomyopathy and functional mitral regurgitation often meet criteria for cardiac resynchronisation therapy to improve left ventricular function as well as mitral regurgitation, and alleviate symptoms. This case shows that implantation of a pacing lead in the coronary sinus to restore synchronous left and right ventricular contraction is feasible, despite the presence of a remodeling device in the coronary sinus.

J. Swampillai (2016) conducted a case report in Ischemic cardiomyopathy and functional mitral regurgitation (n=1). Implantation of a pacing lead in the coronary sinus was evaluated on Feasibility of implantation. Implantation of a pacing lead in the coronary sinus for cardiac resynchronisation therapy is feasible despite the presence of a remodeling device in the coronary sinus.
