Echocardiographic landmark for optimal positioning of CVC tip

"We describe a case of SVC type SVASD, where the SVC-right pulmonary artery crossing point imaged on transesophageal echocardiography was used as an echocardiographic landmark for optimal positioning of the CVC tip" Varsha et al (2021).

Abstract:

Positioning of central venous catheter (CVC) tip in the intrathoracic portion of superior vena cava (SVC) is essential during the surgical repair of superior sinus venous atrial septal defects (SVASD). Although tracheal carina is described as a radiological landmark for positioning the tip of CVCs, it may not be successful at all times. We describe a case of SVC type SVASD, where the SVC-right pulmonary artery crossing point imaged on transesophageal echocardiography was used as an echocardiographic landmark for optimal positioning of the CVC tip.
