Details and patient eligibility

About

The purpose of this study is the evaluation of cardiac and pulmonary response to cardiopulmonary exercise in severe mitral regurgitation and its variation under treatment (surgical mitral valve repair, percutaneous mitral valve repair, optimal medical treatment). The study is conducted as a prospective, observational, single-center study. Patients suffering from symptomatic severe mitral regurgitation will be eligible, if they are referred to the University Hospital of Regensburg, Germany, for further diagnostic procedures and heart team discussion. Cardiopulmonary exercise testing is performed comprising standardized stress echocardiography as well as ergospirometry. Additional detailed assessment will be conducted including standardized questionary, clinical examination, transesophageal echocardiography and measurement of biomarkers.
