Coronary artery stenting for suboptimal PTCA results in acute myocardial infarction in patients treated with Abciximab: early and six-month outcome.
Emergent percutaneous transluminal coronary angioplasty (PTCA) is an effective treatment for acute myocardial infarction. However, occasionally results of angioplasty are suboptimal due to coronary dissection or elastic recoil, leading to a high chance of recurrent ischemia. Coronary stents are occasionally employed in such settings, but a high incidence of stent thrombosis was noted by early investigators when stents were placed into areas of active thrombus formation. ⋯ Three patients experienced recurrent ischemic events within the first 6 months. Two of these events were due to infarct vessel restenosis. We conclude the combined use of coronary artery stents and abciximab for suboptimal PTCA results during acute myocardial infarction is associated with a low incidence of culprit vessel recurrent ischemic events within 6 months of intervention.

Case ReportsUtility of magnetic resonance imaging in a patient with anomalous origin of the right coronary artery, acute myocardial infarction, and near-sudden cardiac death.
A 46-year-old female presented with an acute myocardial infarction and cardiac arrest. Coronary angiography revealed an anomalous origin of the right coronary artery coursing between the aorta and pulmonary artery. Magnetic resonance imaging confirmed the life-threatening nature of this anomaly and led to referral for surgical revascularization.
