Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a randomized, prospective, single-blinded trial to determine the overall rate of successful His-Purkinje conduction system pacing Optimized Trial of Cardiac Resynchronization Therapy (HOT-CRT) versus biventricular pacing using coronary sinus lead (BVP) to compare acute and mid-term outcomes. Acute outcomes include change in QRS duration pre-and post-pacing (degree of QRS narrowing) and incidence of major periprocedural complications (pericardial tamponade, need for lead revision, etc.). Mid-term outcomes include echocardiographic response at 6 months along with a composite clinical outcome of heart failure hospitalization, ventricular arrhythmias, crossover, and all-cause mortality.
