Data are given as mean±SD.
↵* All haemodynamic values were recorded under general anaesthesia during the index session, that is, immediately before and immediately after concluding the procedure (MVR).
CI, cardiac index; CO, cardiac output; LAP, left atrial pressure; LVEDP, left ventricular end-diastolic pressure; MAP, mean arterial pressure; MVR, mitral valve repair; PAP, pulmonary artery pressure; PCWP, pulmonary capillary wedge pressure; PVR, pulmonary vascular resistance; RAP, right atrial pressure; SVR, systemic vascular resistance.
