Successful catheter-based occlusion of persistent left-sided superior vena cava draining into the left atrium

摘要

A 46-year-old woman presented with progressive fatigue. Her past history was remarkable for partial atrio-ventricular septal defect repair at the age of 9 years. Physical examination was notable for obesity, positional desaturation (PaO2 = 92% standing vs. 88% supine) and Grade 2/6 apical pansystolic murmur. Transthoracic echocardiography showed an intact atrial septum and mild mitral regurgitation.
