Excerpt
Cardiac resynchronization therapy (CRT) was developed to restore ventricular synchrony and to improve left ventricular (LV) function and patient functional status. It requires placement of a pacing LV lead, usually via the coronary sinus (CS), to activate the posterolateral (PL) left ventricle prior to its anticipated and delayed depolarization [
1]. However, the LV electrode cannot always be positioned in the preferred lateral or PL locations due to technical factors and anatomic variations in the CS [
2]. Early lead displacements are also the most frequent cause of reintervention. However, the early thrombosis of a coronary vein has been rarely reported [
3]. …
