CMR is an effective adjunctive diagnostic modality that provides superior soft tissue contrast and multi-plane scanning to accurately identify the rare hybrid phenotype of hypertrophic LVNC, overcoming the limitations of echocardiography.
Two case reports expand the hypertrophic LVNC phenotype; leaves open needs for prevalence, natural history, and management data.
To our knowledge, left ventricular noncompaction (LVNC) and hypertrophic cardiomyopathy (HCM) commonly occur as separate disorders in different patients; however, LVNC associated with HCM, which is called hypertrophic LVNC, is relatively rare.1) Here we report two sporadic cases of hypertrophic LVNC which were diagnosed by echocardiography and cardiac magnetic resonance (CMR).
