Inhaled nitric oxide preserves ventricular function during resuscitation using a percutaneous mechanical circulatory support device in a porcine cardiac arrest model: an echocardiographic myocardial work analysis.

BMC Cardiovasc Disord 2021 Apr 17;21(1):189. Epub 2021 Apr 17.

Department of Anesthesiology, Medical Faculty, RWTH University Hospital Aachen, RWTH Aachen University, 52074, Aachen, Germany.

Background: Resuscitation using a percutaneous mechanical circulatory support device (iCPR) improves survival after cardiac arrest (CA). We hypothesized that the addition of inhaled nitric oxide (iNO) during iCPR might prove synergistic, leading to improved myocardial performance due to lowering of right ventricular (RV) afterload, left ventricular (LV) preload, and myocardial energetics. This study aimed to characterize the changes in LV and RV function and global myocardial work indices (GWI) following iCPR, both with and without iNO, using 2-D transesophageal echocardiography (TEE) and GWI evaluation as a novel non-invasive measurement.

Application of a Series of Two-Dimensional Transesophageal Echocardiographic (2D TEE) Views Across Multiple Axes Improves the Accuracy of Tricuspid Annular Measurements.

J Cardiothorac Vasc Anesth 2021 Mar 10. Epub 2021 Mar 10.

Department of Anesthesia, Austin Hospital, Heidelberg, Victoria, Australia.

Objectives: Quantification of the tricuspid annulus (TA) is an important factor in determining the requirement for tricuspid annuloplasty in cardiac surgery. Three-dimensional echocardiography (3DE) has shown that the TA is biplanar with an antero-posterior longaxis and septo-lateral shortaxis, and that the commonly used 2D TEE (two-dimensional transesophageal echocardiography) four-chamber view (4ChV) underestimates the true TA longaxis. The authors hypothesized that the use of multiple 2D TEE TA views could attain greater TA long-axis measurements and smaller TA short-axis measurements than the 4ChV, and that the 4ChV has a significant but inconsistent bias relative to the maximal TA diameter measured by these views.
