Quadripolar Leads in Cardiac€Resynchronization Therapy
Ma Despite the benefit of cardiac resynchronization therapy (CRT) in patients with heart failure and conduction delay, a considerable number of patients do not respond substantially. Left ventricular lead position is an important factor in response, restricted by the patient’s specific anatomy and local pathophysiology. Quadripolar leads could enhance response to CRT, offering 4 pacing location...
متن کاملRepetitive optimizing left ventricular pacing configurations with quadripolar leads improves response to cardiac resynchronization therapy
BACKGROUND This study aimed to investigate whether repetitive optimizing left ventricular pacing configurations (LVPCs) with quadripolar leads (QUAD) can improve response to cardiac resynchronization therapy (CRT). METHODS Fifty-two eligible patients were enrolled and 1:1 randomized to either the quadripolar LV leads (QUAD) group or the conventional bipolar leads (CONV) group. In the QUAD gro...
متن کاملCardiac Resynchronization Therapy Using Quadripolar Versus Non‐Quadripolar Left Ventricular Leads Programmed to Biventricular Pacing With Single‐Site Left Ventricular Pacing: Impact on Survival and Heart Failure Hospitalization
BACKGROUND In cardiac resynchronization therapy (CRT), quadripolar (QUAD) left ventricular (LV) leads are less prone to postoperative complications than non-QUAD leads. Some studies have suggested better clinical outcomes. METHODS AND RESULTS Clinical events were assessed in 847 patients after CRT-pacing or CRT-defibrillation using either QUAD (n=287) or non-QUAD (n=560), programmed to single...
متن کاملCardiac Resynchronization Therapy Leads to Improvements in Handgrip Strength
BACKGROUND A reduction in skeletal muscle performance measured by handgrip strength is common in heart failure. No trial has investigated the role of cardiac resynchronization therapy, which leads to improvements in cardiac performance, on the function of skeletal muscle in patients with heart failure. METHODS Nineteen patients were recruited, 18 male, age 69 ± 8 years, New York Heart Associa...
متن کاملCardiac-resynchronization therapy.
Cardiac resynchronization therapy (CRT) addresses abnormal left ventricular (LV) activation that produces detrimental effects on cardiac systolic and diastolic function. CRT improves symptoms and ventricular performance, promotes reverse remodeling, and decreases mortality and hospitalization in patients with congestive heart failure (CHF). Atrial-synchronized biventricular stimulation reverses...
