Transcatheter mitral valve replacement in rheumatic mitral stenosis under 3-dimensional printing
Rheumatic mitral stenosis has a large patient base and a certain incidence in developing countries. Percutaneous balloon valvuloplasty is one of the main treatments for such patients, but this method is limited by the degree of mitral regurgitation. Here, we describe a 74-year-old patient with rheumatic mitral stenosis without calcification observed by transthoracic echocardiography and computed cardiac tomography, and no calcification was found in the mitral annulus. The score of Society of Thoracic Surgeons was 14.2%, with Wilkins score of 12. Under the guidance of 3-dimensional printing technology, transcatheter mitral valve replacement was successfully performed. Before discharge, the stability and function of the bioprosthesis were confirmed.
