Flowing back and forth: a coronary malformation

The angiogram ( figure 1 , video 1 ) demonstrated a severely dilated RCA feeding a dense net of collaterals, which drained retrogradely into the left coronary artery (LCA) with diastolic run-off into the main pulmonary artery, diagnosing and demonstrating the pathophysiological mechanism of an anoma...

More Information
Summary:The angiogram ( figure 1 , video 1 ) demonstrated a severely dilated RCA feeding a dense net of collaterals, which drained retrogradely into the left coronary artery (LCA) with diastolic run-off into the main pulmonary artery, diagnosing and demonstrating the pathophysiological mechanism of an anomalous LCA from pulmonary artery. [...]increasing numbers of adolescent and adult cases have been described, 1 with a more benign early course due to abundant collateral circulation, presenting later in...
