VP16.20: Persistent left superior vena cava with absent right superior vena cava

[Absent right superior vena cava with left superior vena cava draining to an unroofed coronary sinus].

We describe the case of a 1-month-old infant with a complete atrioventricular septal defect with right dominance, situs solitus, and drainage from the persistent left superior vena cava to the coronary sinus. Corrective surgery was carried out without previous cardiac catheterization. During the operation, the right superior vena cava was found to be absent. Cyanosis and head-and-neck edema wer...

Persistent Left Superior Vena Cava

Persistent left superior vena cava

Persistent left superior vena cava (PLSVC) is the most common congenital malformation of thoracic venous return and is present in 0.3 to 0.5% of individuals in the general population. This heart specimen was dissected from a 35-year-old male cadaver whose cause of death was determined as non-cardiac. The heart was examined and we found a PLSVC draining into the coronary sinus. The right superio...

[Cardiac transplantation in a patient with a persistent left superior vena cava and an absent right superior vena cava].

Persistent left superior vena cava is the most common congenital venous abnormality of the thorax and has a prevalence of 0.5% among the general population.1 Other related malformations include absent right superior vena cava and presence of a left azygos vein. In these situations, the right side of the head and the right arm drain mainly through the innominate vein in the left superior vena ca...

Implantation of Transvenous Permanent Pacemaker in a Patient with Persistent Left Superior Vena Cava and Absent Right Superior Vena Cava

Vascular access has remained a major challenge for implantation of permanent pacemaker leads. A persistent Left Superior Vena Cava (LSVC), especially with an absent Right Superior Vena Cava (RSVC), is a rare finding during pacemaker implantation and is accompanied by technical difficulties. Herein, we describe a case of sinoatrial node arrest, in which finding a suitable vein for passing the le...
