Veno-venous loop through coronary sinus for LV lead placement during cardiac resynchronization therapy

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...

Minithoracotomy as a primary alternative for LV lead implantation during coronary resynchronization therapy

Background Numerous anomalies of cardiac venous system prevent optimal endovascular implantation of LV lead in more than 15% of patients with heart failure and indications for Coronary Resynchronization Therapy (CRT). Insisting on endovenous approach in these patients can be one of the potentional reasons for large number of nonresponders reported in the literature. Purpose of this study was to...

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 nonischemic 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 isc...

Echocardiography-Guided Left Ventricular Lead Placement for Cardiac Resynchronization Therapy: Results of the Speckle Tracking Assisted Resynchronization Therapy for Electrode Region (STARTER) Trial Saba et al: Echo-Guided LV Lead Placement in CRT

Dependency of cardiac resynchronization therapy on myocardial viability at the LV lead position.

OBJECTIVES This study sought to analyze the effectiveness of cardiac resynchronization therapy (CRT) related to the viability in the segment of left ventricular (LV) lead position defined by myocardial deformation imaging. BACKGROUND Echocardiographic myocardial deformation analysis allows determination of LV lead position as well as extent of myocardial viability. METHODS Myocardial deform...
