MitraClip combined with PTSBME for the treatment of obstructive hypertrophic cardiomyopathy with severe mitral regurgitation: a case report

Traditionally, both interventricular septal and mitral valve lesions are treated simultaneously through surgical intervention. However, the surgical conditions are relatively strict, and many patients are unable to undergo surgical treatment, resulting in delays in their condition. For such patients, minimally invasive intervention may be used to simultaneously treat interventricular septal and mitral valve lesions, further reducing surgical risks and enhancing surgical efficacy. In this case, MitraClip combined with PTSBME was first performed. After the surgery, the patient's LVOT obstruction and MR were simultaneously relieved, and clinical symptoms improved significantly.
