Conduction System Pacing Optimized Therapy Study
In Brief
A clinical study evaluating Left ventricular coronary sinus (BiV) configuration, Conduction system pacing-only configuration, and 1 other intervention for Heart Failure. Completed, enrolled 60 participants across 12 sites in 4 countries.
Detailed Summary
The purpose of the CSPOT study is to determine the best mode of cardiac resynchronization therapy (CRT) pacing for different populations of CRT patients, comparing traditional biventricular or left ventricular pacing (BiV), conduction system pacing (CSP)-only, and conduction system pacing optimized therapy (CSPOT) also known as a combination of conduction system pacing (CSP) and left ventricular (LV) pacing. Additionally, safety of the system will be assessed.

Timeline
Interventions
For subjects with a pacemaker, pacing of the left ventricular coronary sinus only. For subjects with a defibrillator, biventricular pacing of the left ventricular coronary sinus and the right ventricle. During the acute protocol, the five AV delays for this intervention include the default AV delay setting, default + 30 milliseconds (ms) AV delay, default + 60 ms AV delay, default - 30ms AV delay, default - 60ms AV delay. Patients with a defibrillator will receive two additional delays LV precedes default by 30ms and LV precedes default by 60ms.
Conduction System Pacing (CSP) of the left bundle branch. During the acute protocol, the five AV delays for this intervention include the default AV delay setting, default + 30 milliseconds (ms) AV delay, default + 60 ms AV delay, default - 30ms AV delay, and default - 60ms AV delay.
A combination of Left Ventricle pacing and Conduction System Pacing of the left bundle branch. During the acute protocol, the eight delays for this intervention include the default AV delay setting, default + 30 milliseconds (ms) AV delay, default + 60 ms AV delay, default - 30ms AV delay, default - 60ms AV delay, CSP precedes default by 30ms, LV precedes default by 30ms and LV precedes default by 60ms.
