Key result
Approximately 20-30% of patients with advanced heart failure and ventricular dyssynchrony do not respond to cardiac resynchronization therapy, highlighting the need for better selection criteria.
Why the study?
A variable proportion of patients with advanced heart failure and ventricular dyssynchrony treated with cardiac resynchronization therapy do not benefit, and better methods to identify non-responders are lacking.
Identifying CRT non-responders remains challenging due to technical limitations of imaging modalities and anatomical constraints of the coronary venous system.

Táborský et al. (2011) conducted a review in Heart failure with ventricular dyssynchrony. Cardiac resynchronization therapy (CRT) was evaluated. Approximately 20-30% of patients with advanced heart failure and ventricular dyssynchrony do not respond to cardiac resynchronization therapy, highlighting the need for better selection criteria.
