Continuous measurement of myocardial oxygen consumption (MVO2) and hemodynamic response during transapical left ventricular bypass (TALVB).
Continuous measurement of hemodynamic parameters during acute TALVB and MVO2, with the use of a fiberoptic coronary sinus catheter, has demonstrated complete removal of ventricular pulsations and reduced mean left ventricular pressure, with maintenance of the systemic circulation. Myocardial O2 demand has been shown to significantly decrease during maximum LV decompression in the presence of a minimally changing O2 supply.
