Figure 1 Angiograms showing successful and unsuccessful reperfusion in patients with right ventricular infarction who underwent primary angioplasty. A shows total occlusion of the right coronary artery proximal to the right ventricular branches (arrow) in a patient before angioplasty, and B shows complete reperfusion after angioplasty, with a thrombolysis in myocardial infarction grade 3 flow in the right main coronary artery and its major right ventricular branches (arrowheads). C shows the complete failure of reperfusion in another patient, with impaired flow in the right main coronary artery, left ventricular branches, and right ventricular branches (arrowhead), attributable to refractory dissection and thrombus (arrows). D shows partial reperfusion in a third patient, with an absence of flow in the right ventricular branches, despite successful reperfusion of the right main coronary artery and its left ventricular branches.
