Background: In this study, the prevalence, characteristics, and clinical significance of concomitant specific cardiomyopathies (CMs) were investigated in subjects with bicuspid aortic valve (BAV). Methods: We retrospectively evaluated 1,186 adults with BAV (850 males, mean age 56 ± 14 years). Left ventricular noncompaction (LVNC), hypertrophic CM (HCM), and idiopathic dilated CM (DCM) were diagnosed when patients fulfilled current clinical and echocardiographic criteria. Clinical and echocardiographic characteristics including comorbidities, heart failure presentation, BAV morphology, function, and aorta phenotypes in BAV subjects with or without specific CM were compared. Results: Overall, 67 subjects (5.6 %) had concomitant CMs: 40 (3.4%) patients with LVNC, 17 (1.4%) with HCM, and 10 (0.8%) with DCM. BAV subjects with HCM had a higher prevalence of diabetes mellitus, heart failure with preserved ejection fraction (HFPEF), and tended to have type 0 phenotype, while BAV subjects with DCM showed a higher prevalence of chronic kidney disease and heart failure with reduced ejection fraction (HFREF). BAV subjects with LVNC were significantly younger, predominantly male, and had greater BAV dysfunction and a higher prevalence of no...Continue Reading

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
