nitial Experience with MultiPoint Pacing Cardiac Resynchronization Therapy in China

Recently, cardiac resynchronization therapy （CRT） with multipoint left ventricular （LV） pacing in a single coronary sinus branch （MultiPointTM Pacing [MPP], St. Jude Medical, Inc., Sylmar, CA, USA） has been introduced commercially. The CRT system with MPP feature offers a new strategy for physicians to further enhance CRT in patients with heart failure. Early clinical studies have shown that MPP, compared with conventional biventricular （BiV） pacing, provides acute benefits to LV dP/dtmax, LV dyssynchrony, LV peak radial strain, and LV electrical activation, and improves CRT response at 12 months. In this report, we presented two MPP CRT cases in China with acute hemodynamic assessment under various MPP and conventional BiV pacing configurations, demonstrating that MPP can offer further benefits to patients.
