Key result
RVOT pacing linked to major clinical improvements after failed CS pacing.
Why the study?
Biventricular pacing via a branch vein of the coronary sinus is not always possible due to anatomical reasons including phrenic nerve stimulation, scarred myocardium, and distorted anatomy.
Does alternative site pacing in the right ventricular outflow tract improve symptoms in patients where coronary sinus pacing is not possible?

Does alternative site pacing in the right ventricular outflow tract improve symptoms in patients where coronary sinus pacing is not possible?
Alternative site pacing in the right ventricular outflow tract may be a viable option for patients requiring biventricular pacing when coronary sinus access is not possible.
No takes yet. Share an insight, caveat, or question.
May warrant RVOT pacing consideration when coronary sinus access fails; hypothesis-generating from this small case series.
Stephen C. Vlay (2003) conducted a case report in Heart failure requiring biventricular pacing (n=3). Alternative site pacing with an electrode in the right ventricular outflow tract was evaluated on Improvement in dyspnea, congestive heart failure, New York Heart Association functional class, and ability to ambulate. Alternative site pacing with an electrode in the right ventricular outflow tract provided major clinical improvements in 3 patients unable to undergo standard coronary sinus pacing.
