Transcatheter mitral edge-to edge repair(mTEER) is a minimally invasive, catheter-based therapy used to treat mitralregurgitation. The gold standard for intraprocedural guidance of mTEER is transesophageal echocardiography (TEE).4-dimensional volumetric intracardiacechocardiography (vICE) is an alternativeimaging modality that provides volumetricimages with multiplanar reconstruction forguidance during structural heart procedures.
