Incremental prognostic value of stress echo positivity in the left anterior descending coronary artery territory.

Background: Dipyridamole stress echo (DSE) positivity is usually titrated according to presence and severity of the induced wall motion abnormalities. The purpose of our study is to assess whether the location of DSE positivity might add to prognostic stratification.

Methods: The study enrolled 112 patients with known or suspected coronary artery disease (CAD) and without a history of prior myocardial infarction.

Primary angioplasty for acute myocardial infarction in a patient with a solitary coronary ostium and a "superdominant" right coronary artery.

Coronary artery anomalies (CAAs) are a rare angiographic finding, sometimes associated with acute coronary events. We report on a case of primary angioplasty for inferior acute myocardial infarction (AMI) in a 66-year-old woman with a solitary coronary ostium in the right sinus of Valsalva and a "superdominant" right coronary artery. We also discuss two potential pitfalls of primary angioplasty: correct interpretation of coronary anatomy and approach to challenging lesions.
