Left Ventricular Dyssynchrony
Rest/Stress Quantification Of Left Ventricular Dyssynchrony By 3D Gated Blood Pool D-SPECT
Cardiac Resynchronization Therapy (CRT) is an established treatment for patients with advanced heart failure and left ventricular dyssynchrony (LVD). Too many patients do not clinically improve with CRT.
- Trial name
- NCT01390532
- Testing
- 3D Blood-Pool Gated SPECT (BPGS) with a new designed cardiac imaging camera (DSPECT, Spectrum Dynamics®, Ceasaria, Israel)
- Where
- France
- Volunteers
- 30 people
- Sponsor
- University Hospital, Clermont-Ferrand
Heart Failure, Systolic, Left Bundle Branch Block
Optimal Coronary Sinus Lead Implantation Using Intracardiac Impedography and Magnetic Resonance Imaging
Despite the dramatic effect of cardiac resynchronization therapy (CRT) on survival and morbidity in people with congestive heart failure, 50-70% of eligible patients do not respond to this intervention.
- Trial name
- NCT01129635
- Testing
- Cardiac Resynchronization Therapy (CRT) implantation
- Where
- United States
- Volunteers
- 38 people

- Trial name
- ProgNOP-LBBB (NCT05654792)
- Testing

AVB - Atrioventricular Block
Left Bundle Branch Pacing Versus Right Ventricular Pacing in Patients With Atrioventricular Block
Although emerging evidence demonstrated that left bundle branch pacing (LBBP) is a promising alternative for patients with either a bradycardia or a heart failure pacing indication.
- Trial name
- NCT05722379
- Testing
- left bundle branch pacing (LBBP), Right ventricular pacing (RVP)
- Where
- China
- Volunteers
- 1,000 people
