Ecocardiografía transesofágica intraoperatoria para evaluar el defecto tipo Gerbode

The Gerbode defect is a rare form of intracardiac shunt from the left ventricle to the right atrium resulting from a defect in the membranous portion of the inter-ventricular septum. This defect can be congenital or acquired, with acquired causes including complications of aortic valve replacements and endocarditis. Intraoperative real time transesophageal echocardiography and 3D echocardiography are vital for diagnosis and anatomic characterization of the shunt. A thorough understanding of echocardiography is necessary to visualize the shunt across various anatomic planes which aids in surgical correction.

Minimally Invasive Approach to the Supradiaphragmatic Inferior Vena Cava

Minimally invasive techniques for cardiac operations have evolved in safety and popularity. To our knowledge, a thoracoscopic technique for control of the inferior vena cava (IVC) has not been previously described. We report a case of a right renal cell cancer with tumor extension into the IVC. Total thoracoscopic isolation and occlusion of the IVC were performed. Intraoperative real-time transesophageal echocardiography confirmed complete cessation of caval flow upon cinching the Rummel tourniquet. As extensive intra-abdominal operations are more often being attempted laparoscopically or robotically, video-assisted thoracoscopic IVC occlusion for proximal control for tumors extending into the cava can be achieved to offer a minimally invasive thoracic approach.
