Key result
A diaphragmatic obstacle in the coronary sinus was successfully passed using a balloon catheter without inflation during CRT implantation, questioning the necessity of venous angioplasty.
Why the study?
Is coronary vein angioplasty necessary to provide cardiac resynchronization in selected patients with coronary sinus obstacles?

Is coronary vein angioplasty necessary to provide cardiac resynchronization in selected patients with coronary sinus obstacles?
This case report suggests that passing a coronary sinus obstacle during CRT implantation may be achieved with an uninflated balloon catheter, potentially avoiding the need for venous angioplasty.
Answers are grounded in this paper and cite their sources.
May allow obstacle navigation without angioplasty in CRT; hypothesis-generating from one case and should not change practice.
Cardiac resynchronization therapy (CRT) has become a recommended method for patients with congestive heart failure (CHF) and cardiac dyssynchrony. In some cases, CRT implantation procedure can be complicated because of anatomic and technical reasons. Some reports describe balloon angioplasty of stenotic heart veins as a method to achieve the target vessel. We present a case of a 58-year-old male with permanent atrial fibrillation and CHF who was referred for CRT. During the implantation of the pacemaker, the diaphragmatic obstacle in coronary sinus (CS) has been passed after many attempts using a balloon catheter with no inflation. The aim of the report is to discuss, in short, the real necessity of venous angioplasty in the CS bed during CRT implantation.

Sterliński et al. (2008) conducted a case report in Congestive heart failure and permanent atrial fibrillation (n=1). Balloon catheter with no inflation was evaluated on Passage of diaphragmatic obstacle in coronary sinus. A diaphragmatic obstacle in the coronary sinus was successfully passed using a balloon catheter without inflation during CRT implantation, questioning the necessity of venous angioplasty.
