Cardiac resynchronization therapy in persistent left superior vena cava: Can you do it two-leads-only?
نویسندگان
چکیده
Introduction Persistent left superior vena cava (PLSVC) is a congenital developmental abnormality of the sinus venosus with an incidence of 0.47% in patients undergoing cardiac implantable electronic devices. The 2 variants include a double superior vena cava (right and left SVC, with or without an innominate vein connecting the two) or a single left-sided SVC (without a right SVC), which may occur in one third of PLSVC subjects. This anatomic variant may hinder pacemaker / cardiac resynchronization therapy (CRT) device implantation, especially when the placement of the left ventricular (LV) lead is concerned.

CRT-D Implantation Through a Persistent Left Superior Vena Cava
A persistent left superior vena cava (PLSVC) was present in a 74 year-old man with dilated cardiomyopathy undergoing implantation of a cardiac resynchronization therapy device with defibrillator (CRT-D). A dual-coil active-fixation defibrillator lead was positioned in the right ventricular apex, followed by a SonR active fixation lead in the right atrial free wall. The coronary sinus lead was a...

INTRODUCTION Persistent left superior vena cava (PLSVC) is a rare congenital anomaly of the superior venous system that may be discovered at the time of cardiac implantable electronic device (CIED) implantation. METHODS AND RESULTS We present a subject who needed cardiac resynchronization therapy (CRT)-CIED implantation and was discovered to have PLSVC with absent innominate vein during the i...
متن کاملRight-sided implantation of a cardiac resynchronization therapy defibrillator in a case of persistent left superior vena cava.
Persistent left superior vena cava represents a congenital venous anomaly that poses a particular obstacle to the implantation of cardiac rhythm management devices. In the present report we briefly describe the rightsided implantation of a biventricular defibrillator in a patient with persistent left superior vena cava. We also briefly discuss the technically challenging procedures applied in s...

We thank Drs van Gelder and Bracke for their response to our paper. Their experience of 4 such cases of coronary sinus (CS) atresia during cardiac resynchronization therapy implantation emphasizes the strong association between this rare anomaly and the presence of a persistent left superior vena cava (PLSVC). They also make an important learning point about the ability of combining subclavian ...

Background: Persistent Left Superior Vena Cava (PLSVC) is a rare congenital anomaly which is typically asymptomatic and discovered incidentally during device implantation. Methods: In this case, we present challenges and techniques of Cardiac Resynchronization Therapy (CRT) in a patient with PLSVC. Results: After evaluating the exact anatomy of PLSVC and Coronary Sinus (CS), we chose the approp...
