Prognostic Significance of the Mitral L-Wave in Patients With Hypertrophic Cardiomyopathy

A mitral L-wave indicates advanced diastolic dysfunction with elevated left ventricular filling pressure. Previous studies have reported that the presence of a mitral L-wave is associated with a poor prognosis in patients with heart failure. However, whether the L-wave can predict adverse events in patients with hypertrophic cardiomyopathy (HC) is still unclear. Therefore, we aimed to investigate the prevalence of a mitral L-wave in patients with HC, and the prognosis of patients with or without an L-wave.
