Catheter-based interventional procedures have become an increasingly offered treatment option for older and high-risk patients, especially in those contraindicated for surgical heart valve repair or replacement, because of frailty and/or comorbidities. Besides aortic valve pathologies, there is a broad spectrum of diseases (rheumatic, degenerative, ischemic and infectious) that may affect the mitral valve in a population that is increasingly aging.
