characterization of suitability of coronary venous anatomy for targeting left ventricular lead placement in patients undergoing cardiac resynchronization therapy
background: differences in the quantity and distribution of coronary veins between patients with ischemic and non-ischemic cardiomyopathy might affect the potential for the left ventricular (lv) lead targeting in patients undergoing cardiac resynchronization therapy (crt). in the current study, we assessed and compared the suitability of the coronary venous system for the lv lead placement in i...
متن کاملComprehensive use of cardiac computed tomography to guide left ventricular lead placement in cardiac resynchronization therapy
BACKGROUND Optimal lead positioning is an important determinant of cardiac resynchronization therapy (CRT) response. OBJECTIVE The purpose of this study was to evaluate cardiac computed tomography (CT) selection of the optimal epicardial vein for left ventricular (LV) lead placement by targeting regions of late mechanical activation and avoiding myocardial scar. METHODS Eighteen patients un...
متن کاملSnare system for left ventricular lead placement in cardiac resynchronization therapy.
A 79-year-old man, previously diagnosed with ischemic heart disease and valve disease, who had undergone coronary artery bypass grafting and aortic valve replacement, was referred for implantation of a cardiac resynchronization system with defibrillator (CRT-D). He was in NYHA functional class III under optimized medical therapy, with left ventricular ejection fraction of 25%, mean QRS of 160 m...
متن کاملThoracoscopic Left Ventricular Lead Implantation in Cardiac Resynchronization Therapy
Cardiac resynchronization therapy is known to reduce morbidity and mortality in patients with advanced heart failure as a result of dyssynchrony and systolic dysfunction of the left ventricle. Placement of the left ventricular (LV) lead via the coronary sinus can be difficult. When LV lead implantation is difficult, a video-assisted epicardial approach can be a good alternative. Although there ...
متن کاملImpacted left ventricular lead technique in cardiac resynchronization therapy.
Left ventricular (LV) lead dislodgement is a significant problem in cardiac resynchronization therapy and re-operation is required to rectify the situation. In this case report, we describe a new technique to stabilize an LV lead which is prone to dislodgement by impacting an inactive LV lead in the same cardiac vein.
