Low Prevalence

Apical Hypertrophic Cardiomyopathy (ApHCM) is a rare variant of hypertrophic cardiomyopathy with a low prevalence in the general population. ApHCM with right ventricular involvement (BiApHCM) is largely unreported and may not be detected with conventional transthoracic echocardiogram (TTE) alone. Cardiac Magnetic Resonance (CMR) has been demonstrated to be a proficient imaging modality to diagnose BiApHCM. We present a case of BiApHCM that was diagnosed with TTE and further characterized by CMR. This imaging modality may be utilized more in the future to help diagnose and detect the prevalence of BiApHCM.

And Function

Hypertrophic cardiomyopathy (HCM) is the most common genetic cardiac disease, and its main characteristic is symmetrical or asymmetrical hypertrophy of the left ventricle and/or right ventricle. Most previous studies mainly include the left ventricle for definition of HCM, thus neglecting the right ventricle. But recently, many studies have reported the right ventricular involvement in HCM. Histopathological results showed that similar pathogenic changes in both the right and left ventricles, which suggests common myopathic processes and sarcomere genetic mutations. Cardiovascular magnetic resonance (CMR) is a gold standard imaging modality to assess heart anatomy and function and provides highly accurate and reproducible measurements. CMR is very useful in characterizing the various phenotypes of right and left ventricles in HCM. CMR also can be useful in detecting early and dominant phenotypic expression of HCM. Due to the complex geometry of the right ventricle and its retrosternal position, echocardiography may not provide accurate measurements. CMR also provides more accurate and repeatable right ventricular measurements. Thus, right ventricle evaluation along with left ventricle should routinely be done for better assessment of HCM patients.

ObjectiveTo determine whether cardiac magnetic resonance imaging (CMR) could be useful in identifying previously undiagnosed cardiomyopathies in a cohort of patients with ischemic stroke who underwent standard etiologic investigation and to describe the type and frequency of these cardiomyopathies.MethodsWe performed a subanalysis of a previously collected prospective cohort of patients with ischemic stroke. Patients with structural changes on echocardiography that are considered causal for stroke in the Trial of Org 10172 in Acute Stroke Treatment (TOAST) classification were excluded. A 3T CMR was performed. We compared the frequency of the cardiomyopathies that we found with reference values for the general population.ResultsOne hundred thirty-two patients with a mean age of 68.4 years were included. In 7 patients (5.3%, 95% confidence interval 2.59%–10.54%) CMR identified cardiomyopathy. Four patients had hypertrophic cardiomyopathy, 2 had restrictive cardiomyopathy, and 1 had noncompaction cardiomyopathy. Six of these patients had been classified after standard evaluation as having undetermined stroke and 1 patient as having cardioembolic stroke (atrial fibrillation). We found a higher frequency of hypertrophic cardiomyopathy in the entire cohort and in the undetermined cause group compared to the general population (3.03% and 5.81% vs 0.2%, respectively, p = 0.001 and p < 0.001). The frequency of noncompaction cardiomyopathy was also higher in our cohort (0.76% vs 0.05%, respectively, p < 0.001).ConclusionsAlthough rare, cardiomyopathies should be considered as a possible cause of ischemic stroke classified as of undetermined etiology after standard evaluation.
