The study was designed to assess the acute haemodynamic effects of IABP coupled with CRT using standard haemodynamic monitoring. In both cases, a marked elevation of V-wave in pulmonary capillary wedge pressure (PCWP) was shown, and a moderate-to-severe functional mitral regurgitation was observed. IABP and CRT resulted in a significant acute improvement in aortic pressure, PCWP, and V-wave amplitude compared with baseline measurements and IABP alone. These results provide a basis for studies examining the haemodynamic effects of IABP support associated with CRT in patients with heart failure refractory to medical therapy. Cardiology, S.
