Intramyocardial hematoma is a rare sequela of percutaneous coronary intervention after acute myocardial infarction. Clinical outcomes of intramyocardial hematoma vary from asymptomatic remission to cardiac death. Close follow-up is imperative. Herein, we report the case of a 69-year-old man who had sustained an acute inferior myocardial infarction. During primary percutaneous coronary intervention to the occluded right coronary artery, an intramyocardial hematoma developed and immediately ruptured into the right ventricle. Because the patient remained hemodynamically stable, a conservative approach was taken. Follow-up with serial multidetector computed tomographic imaging elucidated the course and extent of the hematoma and clearly revealed the healing process. After 1 year, this method of imaging showed complete remission of the hematoma. To the best of our knowledge, this is the 1st use of serial multidetector computed tomography to document the remission of an intramyocardial hematoma that ruptured after complicated percutaneous coronary intervention. We believe that multidetector computed tomography is useful in tracing the natural history of intramyocardial hematomas.
