Objective: The Inter-lead Distance (ILD) between the Right and Left Ventricular (RV and LV) pacing leads may play a role in Cardiac Resynchronization Therapy (CRT) response. We sought to measure the ILD during the CRT procedure in the Left and Right Anterior Oblique (LAO and RAO) fluoroscopy projections and correlated these measurements with Trans-Thoracic Echocardiographic (TTE) reverse remodeling.
The ILD was measured in the LAO and RAO projections to obtain 2 direct (LAO ILD and RAO ILD) and 1 merged bi-dimensional (LAO ILD×RAO ILD Index) body surface-normalized indexes.
Methods and results: Between January and December 2010, 48 consecutive CRT patients were enrolled (15/48, 31.2% with upgrading indications). Fourty-five patients (mean age 72.6 ± 9 years, 28 males) completed the TTE follow up at mean of 12.3 ±.. View More»
