  • The rationale behind early repair in these instances is to treat severe MR before pathological changes have occurred thus preserving patients in a state of normal ventricular and atrial chambers, normal rhythm (i.e. no persistent or permanent disturbances) and good long-term valve function, the aim being to ultimately ensure a survival rate and quality of life identical to the matched population. (escardio.org)
