We report a case of chronic hypoxemia in a 62-year-old woman as a result of biatrial drainage of a right-sided superior vena cava. Radionuclide ventilation and perfusion imaging revealed significant increased radiotracer activity in the kidneys, bowel, and thyroid gland suggesting a right-to-left shunt which was confirmed by contrast enhanced CT of the chest. An anatomically correct right-sided SVC drained through two channels, the larger of which emptied into the roof of the left atrium and a smaller atretic portion feeding the right atrium. We were able to find only nine case reports of this rare anomaly in the English literature. All prior cases demonstrated partial anomalous pulmonary venous return which was also demonstrated to be present in this case with the use of cardiac MRI. According to our literature search, this is one of the few cases to be diagnosed with cardiac MRI.

Left atrial veno-arterial extracorporeal membrane oxygenation (LAVA-ECMO) in cardiogenic shock (CS) is a novel mechanical cardiocirculatory support strategy that provides robust cardiocirculatory support and simultaneous left and right atrial venting by way of a multifenestrated transeptal catheter. We performed a single-center retrospective analysis of all patients aged ≥18 years with CS who underwent LAVA-ECMO at a quaternary care institution from 2018 to 2023. Clinical outcomes and prehemodynamics and posthemodynamics were evaluated.

Background: Regional cardiac tamponade presented as posterior extrapericardial haematomas compressing both atria, with cardiogenic obstructive shock due to inflow abolition is a rare cause of post-percutaneous coronary intervention vascular collapse.
Case Summary: We present such a case where computed tomography-guided anterior pericardiocentesis decompressed the atria and restored cardiac output.
Discussion: Prior coronary artery bypass grafting should not be considered protective from cardiac tamponade in patients in whom perforation occurs, because loculated effusions can develop beneath adhesions of the pericardium and compress various cardiac structures (such as the left atrium or the right ventricle); they appear several hours after the intervention and cause atypical haemodynamic manifestations.

Congenital anomalies of the inferior vena cava are rare but if unidentified may create a risk for complications during surgery. In cardiac surgery, identifying such anomalies is crucial as they may alter the normal conduct of cardiopulmonary bypass. Herein, we describe a case of a 78-year-old women with an anomalous inferior vena cava draining into the superior vena cava, who was referred for surgical management of severe mitral regurgitation.
