Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Intravascular lithotripsy is an approved adjunct interventional therapy in treating calcified lesions to facilitate stenotic lesion opening in peripheral vascular disease and coronary artery disease. The off-label use of current peripheral lithotripsy balloon in mitral valve as a compassionate treatment or as an adjunct treatment before mitral balloon valvuloplasty and transcatheter mitral valve replacement has been reported with success . A possible mechanism is that lithotripsy preferentially impacts hard tissue, disrupts calcium, and leaves soft tissue undisturbed, improving valve pliability, preventing leaflet damage, and making subsequent valvuloplasty safer. However, the off-label use of multiple peripheral lithotripsy balloons in mitral valve is technically complicated.
SmartWave balloon was specifically designed lithotripsy balloon for calcified aortic stenosis. This first-in-human study aims to apply the SmartWave lithotripsy balloon in treating calcified mitral stenosis due to MAC or severely calcified rheumatic mitral valve.
