A Case study on percutaneous mitraclip implantation in severe rheumatic mitral regurgitation
Abstract: Background: Mitra Clip therapy is a minimally invasive, safe, and clinically validated treatment for patients with mitral valve issues. Traditionally, anatomical exclusion criteria for the MitraClip procedure have ruled out cases involving rheumatic heart disease (RHD) affecting the mitral valve, primarily due to its association with mitral stenosis (MS). Case Summary: We present a case involving a 42-year-old male with cardiac and pulmonary sarcoidosis, who experienced recurrent heart failure due …
