Acute severe primary mitral regurgitation (PMR) is poorly haemodynamically tolerated and constitutes a time-critical clinical situation. Prompt identification of the underlying cause and early decision-making about intervention are essential.
This protocol covers patients presenting with acute severe primary mitral regurgitation — a presentation characterised by abrupt haemodynamic compromise that does not allow the cardiovascular system time to adapt.
Urgent surgical or transcatheter intervention is the central strategy. The appropriate procedural option depends on the underlying aetiology — the complete decision algorithm, including the criteria that guide each choice, is available in the full protocol.

Urgent surgery or transcatheter treatment is indicated in patients with acute severe PMR because it is poorly haemodynamically tolerated.
