Hemodynamic Optimization in Cardiac Resynchronization Therapy: Should We Aim for dP/dtmax or Stroke Work? (JACC: Clinical Electrophysiology September 2019)
Description
Hemodynamic optimization may increase benefit from CRT. Typically, maximal left ventricular (LV) pressure rise dP/dtmax is used as an index of ventricular performance. Alternatively, SW can be derived from pressure–volume (PV) loops.
