ABSTRACT

Non-coronary interventional cardiology has for about ten years been undergoing significant development, with the arrival of new percutaneous procedures in various domains. Some of them have already been well validated, notably percutaneous mitral comissurotomy, percutaneous closure of inter-atrial (IA) communications and patent foramen ovale, trans-septal catheterisation, and alcohol septal ablation of hypertrophic obstructive cardiomyopathy. Other interventional techniques are still in the validation phase, such as the techniques for percutaneous occlusion of the left atrium, percutaneous implantation of valvular prostheses, or the new approaches to percutaneous treatment of mitral valvulopathy. The rapid development of these techniques has benefited widely from the use of echocardiography in the catheter suite, providing a very precise clarification of the anatomy and continuous guidance during procedures. This echocardiographic guidance provides optimal results for the interventional procedure and reduces the incidence of complications.
