Insights
Apical hypertrophic cardiomyopathy (HCM) is a rare heart condition. This case shows its rapid development and diagnostic challenges in a patient with hypertension and a kidney transplant.
Area of Science:
- Cardiology
- Cardiovascular Imaging
- Genetics
Background:
- Apical hypertrophic cardiomyopathy (HCM) is an uncommon form of HCM.
- It presents unique diagnostic challenges compared to other HCM variants.
Observation:
- A 43-year-old female with hypertension and a history of kidney transplantation experienced syncope and dyspnea.
- Electrocardiogram revealed diffuse giant T-wave inversions.
- Cardiac MRI confirmed HCM with circumferential apical thickening.
Findings:
- The patient's presentation and imaging findings are consistent with apical HCM.
- The case illustrates the potential for rapid progression of this condition.
Implications:
- This case underscores the importance of recognizing the distinct features of apical HCM.
- Advanced imaging techniques like cardiac MRI are crucial for accurate diagnosis.
- Understanding rapid development is key for timely intervention in apical HCM.
Abstract:
Apical hypertrophic cardiomyopathy (HCM) is a rare variant of HCM. A 43-year-old female with a past medical history significant for hypertension and kidney transplantation presented with recurrent syncopal episodes and dyspnea on exertion. Electrocardiogram showed characteristic diffuse giant T-waves inversion, and cardiac magnetic resonance showed HCM with circumferential apical thickening. This case highlights the rapid development of apical HCM and its challenging diagnostic characteristics.

Layers of the Heart Wall
The myocardium, the thickest layer, consists of cardiac muscle cells interconnected by intercalated discs and crisscrossing connective tissue fibers. These muscle fibers contract...
Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
