Left Epicardial vs. Best-site Right Ventricular Transvenous Pacing in Congenital Heart Block Patients: Ventricular Function Comparisons using 2 D Speckle Imaging

Background: Pacemaker implantation is recommended in symptomatic patients with congenital complete heart block (CHB) with either an epicardial (epi) or transvenous (TV) approach depending on patient age / size. However, there is a paucity of data on updated left ventricle (LV) functional indices between the two approaches. Objective: Our aim was to compare LV function using speckle strain imaging in patients with LV Epi vs. best site right (R) TV pacing Methods: This was a single center, retrospective study of patients with isolated CHB …
