title: Spontaneous closure of post-intervention left anterior descending coronary pseudoaneurysm.
abstract: Coronary pseudoaneurysms are an unusual finding during coronary angiography and there are very little data on their prognosis in the literature. We report the case of a 62-year-old man admitted with an anterior myocardial infarction who developed a pseudoaneurysm in the mid left anterior descending artery some days after a type I coronary perforation during coronary angioplasty. Spontaneous closure of the pseudoaneurysm was observed during hospital follow-up. Spontaneous closure of coronary pseudoaneurysms may be more common in clinical practice than previously thought, but few cases have been reported. As the natural history of post-intervention coronary pseudoaneurysms has been little investigated, reports of their occurrence may help to clarify their evolution.
