Conduction System Pacing in a Patient with Persistent Left Superior Vena
Cava and Absent Right Superior Vena Cava.
Abstract
An 83 year-old man underwent attempted cardiac resynchronization therapy
(CRT-P), but was found to have a persistent left superior vena cava
(SVC) and absence of a right SVC. Additionally, no suitable coronary
sinus (CS) veins were found. Instead, conduction system pacing with a
modified approach was used.
