Iatrogenic mitral stenosis following transcatheter aortic valve replacement (TAVR).

A 57 year old female underwent transcatheter aortic valve replacement (TAVR) for severe aortic stenosis. Mild iatrogenic mitral stenosis was noted intraoperatively. Attempts to reposition the device were hampered by aortic angulation. One year later, severe mitral stenosis was confirmed on transoesophageal echocardiography. It is important to recognise that iatorgenic mitral stenosis due to TAVR may progress over time. Care should be taken to minimise the risk of this rare complication.
