Acute type B aortic dissection following transcatheter mitral valve edge-to-edge repair: a case report.

Herein, we presented a rare complication following transcatheter mitral valve edge-to-edge repair that was most likely related to the transoesophageal echocardiography probe-type B aortic dissection. We postulated that repetitive flexion of the transoesophageal echocardiography probe led to compression-induced injury to the descending aorta wall at the mid-oesophageal level, which was the most probable aetiology of type B aortic dissection. Although this complication is rare, it is potentially fatal and therefore needs attention.
