Cardiology Conference-CVC 2026

Cardiac resynchronization therapy (CRT) is a highly advanced cardiac therapy for patients with heart failure and ventricular dyssynchrony, meaning that the heart's ventricles do not contract in a synchronized manner. CRT achieves contraction synchronization of the left and right ventricles using a specialized biventricular pacemaker, improving efficiency of the heart, optimizing blood flow, and addressing heart failure symptoms such as fatigue, shortness of breath, and fluid retention. CRT is specifically effective for heart failure patients with reduced ejection fraction and conduction abnormalities including left bundle branch block.

CRT improves mortality, decreases hospitalizations, and improves quality of life in appropriately selected heart failure patients. Modern CRT devices often include pacing and defibrillation capabilities (CRT-D) that can provide both resynchronization and arrhythmia protection. The procedure consists of implanting pacing leads in the right atrium, right ventricle and, optional in coronary sinus, to achieve optimal synchronization of the ventricles. As device programming, imaging guided lead placement, and remote monitoring continue to evolve, CRT therapy can be customized and personalized to each individual to allow for their full potential benefit. CRT represents an important pillar of modern heart failure therapy as it restores synchronized contractions and improves cardiac output, thus alleviating symptoms and ultimately providing cardiovascular benefits.""
