Conclusion:
MG shows time-varying and condition-depended dynamics
periinterventionally. Patients with persistent increased (≥4.5 mmHg) MG
at discharge showed the worst functional outcomes and the highest
12-month mortality, followed by patients with an intra-hospital decrease
in MG to values below 4.5 mmHg. Pre-interventional echocardiographic and
procedural parameters can predict unfavourable postprocedural MG.
