Optimizing cardiac resynchronization therapy in advanced heart failure.

Up to 30% of cardiac resynchronization therapy (CRT) patients are considered to be "nonresponders." While the absolute number might increase because of the increased use of CRT, this proportion remains stable. As a result, there is a pressing need for guidelines for practicing clinicians to maximize the effectiveness of CRT. This clinician update describes easy-to-comprehend cases that might provide a practical insight for cardiologists, as well as for all professionals who take care of patients with heart failure who have undergone CRT.
