Abstract

Invasively measured pulmonary capillary wedge pressure (PCWP) has been widely used as a surrogate for left ventricular (LV) filling pressure and facilitates optimization of treatment in critically ill patients with significant cardiovascular pathologies. It is ideally measured by an invasive Swan-Ganz floating catheter. However, many recent studies have shown that its use in patients with myocardial infarction or other respiratory disease increases morbidity and mortality. Thransthoracic doppler echocardiography offers a safer and quicker alternative for the assessment of LV filling pressures.
