Project description:A 40-year-old man was admitted with necrotising fasciitis of the right thigh. Further workup to evaluate for an infectious source revealed an incidental finding of persistent left superior vena cava via transesophageal echocardiography. This finding was confirmed by cardiac MRI. During his hospitalisation, he also developed altered mental status which was found to be secondary to systemic emboli by a head MRI. The primary source of infection was likely his dental abscesses. He underwent intravenous antibiotic therapy for a total of 6 weeks and was then referred to a specialised vascular centre for further management of his congenital anomaly.
Project description:Combined persistent left superior vena cava entering the left atrium with a congenitally atretic coronary sinus is a rare imaging finding. In the absence of a significant right-to-left shunt, it is generally asymptomatic and can be an incidental discovery. Assessing the anatomy of the cardiac vasculature is crucial before transcutaneous cardiac procedures. (Level of Difficulty: Intermediate.).
Project description:We report a case of an anomalous drainage of the right superior vena cava to the left atrium with intact atrial septum associated with Tetralogy of Fallot, pulmonary atresia, and major aortopulmonary collateral arteries.
Project description:A patient with Marfan syndrome undergoing Bentall operation was found to have an absent right superior vena cava and persistent left superior vena cava. The dilation of coronary sinus raised the suspicion of persistent left superior vena cava. The diagnosis was confirmed by agitated saline contrast echocardiography and computed tomography of the chest.
Project description:Persistent left superior vena cava (PLSVC) draining into the coronary sinus is not uncommon, but to the left atrium is a rare condition. Such anomaly may be a cause of unexplained hypoxia in all age groups. It is often diagnosed accidentally during cardiovascular diagnostic work-up or in a contest of other cardiac investigations. We report two cases of these rare PLSVC associations with subsequent medical and surgical management.
