Insights
A myocardial infarction resolved a hypertrophic obstructive cardiomyopathy (HOCM) gradient. This case highlights an unusual spontaneous HOCM course, termed "pseudomyectomy," due to heart attack complications.
Area of Science:
- Cardiology
- Internal Medicine
- Pathophysiology
Background:
- Hypertrophic obstructive cardiomyopathy (HOCM) is a genetic heart muscle disease.
- Left ventricular outflow tract (LVOT) obstruction is a hallmark of HOCM.
- Myocardial infarction (MI) can lead to significant cardiac remodeling.
Abstract:
A 73-year old female patient is known to have hypertrophic obstructive cardiomyopathy (HOCM) since 1989. After a transmural anterolateral myocardial infarction with the development of a large apical aneurysms of the anterior wall, a previously measured gradient of 110 mm Hg in the LVOT is no longer detected. As a consequence of this casuistry, "pseudomyectomy" caused by myocardial infarction is described as an example of an uncommon spontaneous course of HOCM.
