Anomalous left hepatic vein draining into coronary sinus imaged with multidetector computed tomography

Anomalous connection of the left hepatic vein to coronary sinus in a child with PAPVD. Surgical significance and diagnostic difficulties

“…Direct venous drainage of a single hepatic vein into the coronary sinus should not have any clinical or hemodynamic consequences. Nevertheless, it has been suggested that it may be associated with atrial arrhythmias and could lead to technical difficulties during coronary sinus approach procedures [ 3 ]. While undiagnosed prior to surgery, the anomaly might be found during inspection of the inferior vena cava region either by placing a loop around the vessel, or preparing the site for direct caval cannulation.…”

“…The anomalous vein is usually a single vessel that arises from the left hepatic lobe, passes through the diaphragm and joins the body of the coronary sinus close to its orifice [ 2 ]. In most published cases, the anomaly was found incidentally during diagnostic assessment [ 3 – 5 ] or surgery [ 2 ]. The anomaly is of no clinical or hemodynamic significance, unless the patient is qualified for heart surgery.…”

Isolated left hepatic vein draining into the coronary sinus: a rare anomaly encountered during mitral valve surgery

“…Diligent search of literatures by PubMed detected only four case reports in adult 1–3 . Three cases were diagnosed incidentally by computed tomography (CT) 2 , 3 , and the other was found during a coronary artery bypass surgery 1 . All the patients were asymptomatic.…”

Cyanosis in a patient after Fontan palliation due to unrecognised hepatic vein to coronary sinus communication

“…Drainage of a (usually left-sided) hepatic vein to the coronary sinus is an extremely rare abnormality with very few cases described in the literature. [1][2][3] Embryologically, it results when the left horn of the sinus venosus (which forms the coronary sinus) forms a persistent connection with the left vitelline vein system, thereby creating the left hepatic vein to coronary sinus communication. 1,4 In most cases, this anomaly is of no clinical consequence.…”
