“…An increase in wall thickness of 5 to 7 mm in 26 months was considered implausible secondary to HCM, and, as expected in myocarditis, septal hypertrophy resolved on follow-up. The finding of transient LVH in myocarditis has been rarely described in the literature previously, 7 , 8 and the incidence remains unknown.…”

A 40-year-old man with Marfan syndrome presented with chest pain and troponin elevation. Urgent echocardiography was suggestive of hypertrophic cardiomyopathy, but cardiovascular magnetic resonance identified features of acute myocarditis. Repeated imaging 4 months later showed resolution of septal thickness, confirming acute myocarditis. ( Level of Difficulty: Intermediate. )

“…2 Prior studies have pointed out that HCM may sometimes manifest in a manner that resembles myocardial infarction. [3][4][5][6] Furthermore, there is a documented case indicating that myocardial edema, observed during the acute phase of Takotsubo syndrome 7 or myocarditis 8,9 Prior to the acute event, the patient underwent an echocardiogram, which revealed no alterations. Consequently, the observed increase in wall thickness of 5-7 mm over an 18-month period was deemed improbable as a result of HCM.…”

“…Furthermore, there is a documented case indicating that myocardial edema, observed during the acute phase of Takotsubo syndrome 7 or myocarditis 8,9 can also mimic HCM. Myocardial fluid balance relies on microvascular filtration, interstitial hydration, cardiomyocyte water uptake, and lymphatic drainage.…”

This case study presents a 53-year-old male with a history of myopericarditis who experienced retrosternal pain, shortness of breath, and sweating. Initial electrocardiogram indicated ST segment elevation in the inferior leads and T-wave inversion in the lateral leads. Echocardiogram exhibited marked hypertrophy of the posterior wall (18mm) and moderate hypertrophy of the infero-septal wall. While biventricular systolic function was preserved, both the posterior wall and infero-septal wall displayed regions of hypokinesis. Following admission, the patient underwent cardiac catheterization, revealing thrombotic occlusion of the second obtuse marginal branch. Subsequent monitoring showed no recurrence of chest pain or arrhythmias, and the patient’s condition remained stable. A follow-up echocardiogram displayed displayed hypertrophy of the posterior wall (17mm) and a slight increase in infero-septal wall thickness (13mm). Left ventricular systolic function exhibited mild depression, characterized by an average ejection fraction of 44%. Cardiac MRI after three months revealed normalized wall thickness, persisting regional dysfunction, and pericardial effusion. This case highlights the dynamic nature of ventricular wall thickening during acute artery occlusion, indicating the role of wall edema. It emphasizes the importance of comprehensive imaging for accurate diagnosis and management of complex cardiac conditions.
