Comprehensive 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 کاملcharacterization 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 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 کاملMinimal invasive epicardial lead implantation: optimizing cardiac resynchronization with a new mapping device for epicardial lead placement.
To optimize resynchronization in biventricular pacing with epicardial leads, mapping to determine the best pacing site, is a prerequisite. A port access surgical mapping technique was developed that allowed multiple pace site selection and reproducible lead evaluation and implantation. Pressure-volume loops analysis was used for real time guidance in targeting epicardial lead placement. Even th...
متن کاملMaximal electric separation-guided placement of right ventricular lead improves responders in cardiac resynchronization defibrillator therapy.
BACKGROUND Cardiac resynchronization therapy is widely used for the treatment of heart failure. Recent data suggest that electric separation during left ventricular pacing varies within the right ventricle (RV). We hypothesized that placement of the RV lead guided by maximal electric separation (MES) would improve response to cardiac resynchronization therapy compared with standard apical place...
