Bioprosthetic Mitral Valve

Much has changed since the introduction of surgical valve repair in the 1950s, from the introduction bioprosthetic valves to percutaneous approaches to valve repair. Yet, despite substantial advancements in bioprosthetic valve technology, there has been a lack of direct, independent comparison between bioprosthetic mitral valve devices, accompanied by a marked heterogeneity in approaches to the sizing and selection thereof. Wang et al. have hence endeavoured to evaluate, head-to-head, the technical successes and biomechanical outcomes associated with three different bioprosthetic mitral valves (Epic, Abbott, IL; Mosaic, Medtronic, MN; Mitris Resilia, Edwards Lifesciences, CA) in a porcine model, under standardised haemodynamic and anatomical conditions. With a robust experimental technique, they have made clear the heterogeneity in both sizing and biomechanical properties between bioprosthetic mitral valves, and have further emphasised the need for a uniform approach to the manufacturing and sizing of bioprosthetic valves.

In 1961, K Merendino ‘in pure curiosity’, while tracking the murmur of mitral regurgitation, placed his stethoscope ‘on the vertex of the head’, and ultimately led to a medical curiosity and exam finding that not only bears his name, but awes medical learners at all stages of their careers. Merendino and colleagues collected seven such cases of the ‘Murmur on Top of the Head’ building on the work of others who provided a detailed description of mitral regurgitation and noted murmur radiation to the neck and cervical/lumbosacral spine. The majority of patients suffered from rheumatic heart disease or subacute bacterial endocarditis in native heart valves. Here, we report on a case of the ‘Murmur on Top of the Head’ and provide the reader/listener with a direct recording of the ‘Merendino murmur’ (as well as its spinal correlate) in an elderly woman with a bioprosthetic mitral valve.
