Pulmonary Artery Catheter Placement Using Transesophageal Echocardiography.
To assess the feasibility of pulmonary artery catheter placement using transesophageal echocardiography inclusive of a description of the technique. ⋯ Transesophageal echocardiography is a viable adjunctive method to conventional pressure waveform placement of pulmonary artery catheters in potentially difficult patients.

Observational StudyBedside Assessment of the Microvascular Venous Compartment in Cardiac Surgery Patients With Valvular Diseases Undergoing Cardiopulmonary Bypass.
Blood volume reserve for venous return and the effects of cardiopulmonary bypass (CPB) on microvascular bed partitioning and blood flow were examined in patients with valvular diseases. ⋯ Cardiac surgery patients have a limited blood volume reserve for venous return due to a reduced microvascular bed capacitance. This study demonstrated that during CPB a positive fluid balance induced an extravascular pressure increase and further reduced blood volume reserve.
