Utility of three-dimensional transesophageal echocardiography to guide transseptal positioning of a single multistage venous cannula to provide both venous drainage and indirect left ventricular venting in veno-arterial extracorporeal membrane oxygenation.

ABSTRACT: A patient with heart failure due to dilated ischemic cardiomyopathy presented in cardiogenic shock for institution of veno-arterial extracorporeal membrane oxygenation as a bridge to cardiac transplantation. To provide adequate venous drainage and simultaneous decompression of the left atrium (indirect left ventricular venting), a single venous cannula was placed across the interatrial septum so that the distal orifice and side ports were located within the left atrium and the proximal set of side ports were positioned at the cavoatrial junction. Three-dimensional transesophageal echocardiography demonstrated utility in guiding cannula placement and appropriate positioning within the left atrium.

Project description:BackgroundChildren who need to have major surgery or are critically ill often require the insertion of a central venous catheter (CVC). To avoid serious complications, it is important to correctly position the CVC tip at the junction of the distal superior vena cava and the right atrium (cavoatrial junction). Transthoracic echocardiography (TTE) can be used to confirm the correct position of the CVC tip. However, the accuracy of TTE for CVC tip positioning has mainly been investigated using chest X-ray as the reference method-although chest X-ray itself does not allow directly locating the CVC tip at the cavoatrial junction.AimsWe aimed to determine if TTE can help exactly position the CVC tip at the cavoatrial junction during CVC insertion in children. We specifically tested the hypothesis that TTE-guided CVC tip positioning results in a correct CVC tip position at the cavoatrial junction (confirmed by transesophageal echocardiography (TEE) as the reference method) in ≥ 90% of the children.MethodsThis was a prospective observational study in children aged 0-14 years scheduled for elective surgery for congenital heart disease. Our primary endpoint was the proportion of children in whom TTE guidance resulted in a correct CVC tip position at the cavoatrial junction, confirmed by TEE.Results150 children were analyzed. TTE-guided CVC tip positioning resulted in a correct CVC tip position at the cavoatrial junction in 136 children (91%, 95% confidence interval: 85%-94%). The proportion of children in whom TTE guidance resulted in a correct CVC tip position at the cavoatrial junction was highest in children aged 0-3 months (96%) and lowest in children aged 13-14 years (70%).ConclusionTTE-guided CVC tip positioning resulted in a correct CVC tip position at the cavoatrial junction, confirmed by TEE, in 91% of children. Clinicians should consider using TTE to position the CVC tip at the cavoatrial junction during CVC insertion in children-particularly younger children.Trial registrationGerman Clinical Trial Register: DRKS00028271.
