Ra svc junction
Tīmeklis2024. gada 16. marts · At the junction with the right atrium (RA), the SVC (asterisks) is located posterolateral to the ascending aorta (AA), anterior to the right pulmonary artery (RPA), and anteromedial to the right superior pulmonary vein (RSPV). IMV, internal mammary vein; LBCV, left brachiocephalic vein; RBCV, right brachiocephalic vein. … TīmeklisMethods and Results: RA-SVC conduction was evaluated using the RHYTHMIA system in 113 patients (age 62.8±11.5 years, paroxysmal: 67) with atrial fibrillation (AF) after pulmonary vein (PV) isolation. In 56 patients, a line of conduction block was found to run obliquely just above the sinus node (Block group).
