We thank Dr Balacumaraswami and colleagues for their interest in our study on the acute effects of left ventricular (LV) restoration on cardiac performance. We prefer to answer in reverse order.
The reason for not giving any information on mitral regurgitation (MR) was the absence of significant perioperative MR in our patient group, all of whom underwent routine echocardiographic examinations. Concerning MR, McCarthy

referred to Di Donato and colleagues,

revealing that 10% of their patients had preoperative MR and 38% of their patients had had MR develop by 1 year after LV restoration, whereas immediately after surgery the patients were free from MR. When present, MR may offload the left ventricle; however, offloading will not change contractile state. Recently we

demonstrated that acute decrease in LV afterload by intra-aortic balloon pumping resulted in instantaneous increases in stroke volume but not in an increase of contractile state.
