Historical Perspective on Percutaneous Mitral Valve Repair

There has been rapid progress in interventional cardiology in recent years, most especially in valve surgery. What used to be possible only with open-heart surgery is now performed using percutaneous technique. Ten years ago, elderly patients with symptomatic severe aortic stenosis or mitral regurgitation (MR) who were considered high risk for surgical intervention were refused surgery. Life expectancy was reduced, especially if such lesions occurred with coronary artery disease or impaired left ventricular function. In the last decade, however, a technical revolution with new devices and better quality imaging has transformed the lives of patients who are poor surgical candidates. The quality of life of such patients has been improved with percutaneous repair. Transcatheter aortic valve implantation for severe aortic stenosis or medical device (MitraClip) for severe mitral regurgitation (MR) is now feasible. Predominantly, elderly patients now have an option to improve their quality of life and live longer. The techniques are gradually being introduced for patients who are not considered to be high risk for surgery. Hence, the number of patients for percutaneous valve procedures is expanding. Interventional cardiologists and cardiothoracic surgeons are teaming up to an improved approach to treat valvular heart disease.
