1-4) Patients with right ventricular infarction due to RCA occlusion have a poor prognosis and are at high risk of disturbances in conduction at the atrioventricular node, (5,6) whereas patients with occlusion of the circumflex artery are thought to have a good prognosis.
Women who are positive for anti-SSA/Ro and anti-SSB/La autoantibodies have a baseline 2% chance that fibrosis of the atrioventricular node and heart block will develop in the fetus, but that risk increases 10-fold if they have had a previous child with either heart block or a facial rash, she said.
