Valvular heart disease in Japan: Characteristics and treatment of patients in acute care hospitals in 2019

Valvular heart disease (VHD) is one of the commonest causes of cardiovascular morbidity and mortality worldwide, with acquired VHD especially prevalent in countries with aging populations. The scope and pattern of disease are not well understood, as some patients are asymptomatic and available optio...

Description
Summary:Valvular heart disease (VHD) is one of the commonest causes of cardiovascular morbidity and mortality worldwide, with acquired VHD especially prevalent in countries with aging populations. The scope and pattern of disease are not well understood, as some patients are asymptomatic and available options for invasive treatment vary by affected valve. We sought to understand the burden of VHD in Japan including the distribution of patients by valve disease type and age, using administrative claims data from acute care hospitals. This was a retrospective descriptive study of patients with VHD diagnosis and at least one record of echocardiography in 2019 documented in the Medical Data Vision database. Affected valve(s) and type of valve disease were characterized using ICD-10 codes; patients undergoing invasive treatment for VHD at the same facility and during the same year as their diagnosis were assessed using procedure codes. Of 203,398 patients with VHD diagnosis and a record of echocardiography in 2019, 49.0 % had a mitral valve disorder, 44.9 % aortic valve, 22.9 % tricuspid valve, and 2.2 % pulmonic valve (14.9 % of patients had more than one disordered valve). A total of 7201 patients (
