Introduction:
Hypertrophic cardiomyopathy (HCM) is the most common genetic cardiovascular disorder and a significant cause of sudden cardiac death. Cardiac magnetic resonance (CMR) imaging can be a valuable tool for assessment of detailed information on size, localization, and tissue characteristics of hypertrophied myocardium. However, there is still little knowledge of long-term evolution of HCM as visualized by magnetic resonance imaging (MRI). Recently, our group reported a case of left lateral wall HCM as a rare variant of the more common forms, such as septal HCM, or apical HCM. As this patient underwent initial cardiac MRI more than 20 years ago, we are able to provide the thrilling experience of an ultra-long MRI follow-up presentation in this rare case of left lateral wall hypertrophy, including the tremendous improvements in imaging quality within the last two decades of CMR imaging.

Case Report:
A 52-year-old male presented himself to the emergency department of our institution suffering an episode of nocturnal chest pain. As the electrocardiogram showed ventricular tachycardia, synchronized electrical cardioversion was performed, successfully terminating the arrhythmia. Afterwards, the patient was subjected to sequential clinical investigations, excluding ischemia as cause for the serious symptoms, and CMR imaging, revealing an atypical form of HCM....
