초록 ▼

A transcoronary sinus pacing system comprising a sheath having a lumen, a pacing catheter having a pacing needle, wherein the catheter can be advanced within the lumen and placed in the LV summit, and a right ventricular pacing device. A LV summit pacing device. An early mitral valve closure pacing device configured to operate with a right ventricular apex pacing device. A method for implanting a pacing device at a target coronary sinus tissue location, wherein the target can be the posterior LV summit. A method for achieving early closure of a mitral valve. A method for using visualization devices such as fluoroscopy or ultrasound and/or catheter features such as a radiopaque marker to locate a target location for LV pacing and to avoid piercing an artery or the pericardium when anchoring the LV pacing electrode.
