Heart valve assembly systems and methods configured for medical interventional procedures. In one aspect, the methods and systems involve a modular approach to treatment. 1an anchor, the anchor including structure residing above and below a valve annulus and an interior; anda valve assembly defining structure configured to be implanted separately from the anchor and having an exterior sized and shaped to lockingly and directly engage the interior of the anchor.. A heart valve assembly system for implantation at an interventional site, comprising: This document is a continuation of U.S. application Ser. No. 15/378,737 filed Dec. 14, 2016, which is a continuation of U.S. application Ser. No. 14/677,665 filed on Apr. 2, 2015, which is a continuation of U.S. application Ser. No. 13/842,490 filed on Mar. 15, 2013, which claims the benefit of: U.S. Provisional Application Ser. No. 61/635,741 filed on Apr. 19, 2012, and U.S. Provisional Application Ser. No. 61/669,383 filed on Jul. 9, 2012, the entire disclosures of these previous applications being expressly incorporated herein.The present disclosure relates to medical interventional systems and methods and more particularly, to artificial valve assembly systems and methods. The long-term clinical effect of valve regurgitation is well recognized as a significant contributor to cardiovascular related morbidity and mortality. In particular, there are two basic classifications of mitral regurgitation (“MR”), primary and secondary. Primary MR results when there is either direct tissue pathology of the valve structures or there is structural damage/alteration of one or more valve structures (leaflets, chordae). Secondary MR is a functional loss of valve competence caused left ventricular dilatation, and secondary alteration of mitral valve geometry following damage to the myocardium and left ventricle (“LV”) causing. Whether valvular in origin leading to a ventricular problem or of ventricular/muscle origin leading to the ...
