Transthoracic echocardiography visualization of bicaval dual lumen catheters for veno-venous extracorporeal membrane oxygenation.
Summary of "Transthoracic echocardiography visualization of bicaval dual lumen catheters for veno-venous extracorporeal membrane oxygenation."
Bicaval dual lumen catheters improve the efficiency of veno-venous extracorporeal membrane oxygenation by minimizing recirculation with an innovative design, which requires precise placement of three catheter ports in the superior vena cava, right atrium, and inferior vena cava, respectively. However, the exact position of these catheter ports is usually not known during placement because they cannot be visualized with conventional radiography. We performed a retrospective review of our experience over the past year using transthoracic echocardiography to evaluate the position of the catheter ports. From a subcostal, sagittal imaging approach, we were able to identify all three catheter ports in 11 of 11 studies. At least one of the catheter ports was incorrectly positioned in 5 of 11 studies. Further prospective evaluation is necessary to determine if catheter repositioning based on transthoracic echocardiography findings can further improve the clinical efficiency of veno-venous extracorporeal membrane oxygenation. © 2012 Wiley Periodicals, Inc.

Medical and Biotech [MESH] Definitions
Ultrasonic recording of the size, motion, and composition of the heart and surrounding tissues. The standard approach is transthoracic.
Echocardiography amplified by the addition of depth to the conventional two-dimensional ECHOCARDIOGRAPHY visualizing only the length and width of the heart. Three-dimensional ultrasound imaging was first described in 1961 but its application to echocardiography did not take place until 1974. (Mayo Clin Proc 1993;68:221-40)
Catheters designed to be left within an organ or passage for an extended period of time.
Pulmonary Veno-occlusive Disease
Pathological process resulting in the fibrous obstruction of the small- and medium-sized PULMONARY VEINS and PULMONARY HYPERTENSION. Veno-occlusion can arise from fibrous proliferation of the VASCULAR INTIMA and VASCULAR MEDIA; THROMBOSIS; or a combination of both.
Echocardiography, Doppler, Color
Echocardiography applying the Doppler effect, with the superposition of flow information as colors on a gray scale in a real-time image.
PURPOSE: Venovenous extracorporeal membrane oxygenation is used increasingly in adults with severe acute reversible respiratory failure. Cannulation is associated with a risk of vascular damage or car...
We conducted an epidemiologic survey in France on the use of bicaval dual-lumen cannulas for extracorporeal membrane oxygenation (ECMO). Every service that used the Avalon cannula was contacted. Pract...
Objectives. This study compares image quality, cost, right ventricular ejection fraction analysis, and baffle visualization between transthoracic echocardiography and cardiac magnetic resonance ima...
Coronary artery fistula is a rare abnormality of coronary circulation. It is mostly congenital but acquired forms can also occur. Fistulae are usually asymptomatic and can sometimes be visualized duri...
PURPOSE: Proper cannula positioning in single site veno-venous extracorporeal life support (vv-ELS) is cumbersome and necessitates image guidance to obtain a safe and stable position within the heart...
Bloodstream infections are common in Intensive Care Units (ICUs). The need of a central venous line increases the risk of bacteremia and central venous catheter (CVC) related infections. T...
We sought to determine whether the dual-source computed tomography assessment of aortic valve stenosis and coronary artery disease is equivalent to or even better than conventional invasiv...
Until today it was not possible to reliably assess the function of a new bypass, i.e., to measure myocardial perfusion. Measuring intramyocardial blood flow directly after revascularisatio...
Non-invasive evaluation of patients with stable angina and unstable coronary syndromes with transthoracic Doppler echocardiography to evaluate presence of significant coronary stenoses. Bl...
The purpose of this study is to (1) demonstrate the efficacy and safety (toxicity) of 25 mg/kg/day of Defibrotide in patients with severe veno-occlusive disease (sVOD) and (2) evaluate ser...
