![]() ![]() In two recent studies we focused on the Coaptation Triangle and on the Mitral Scallops, describing how their geometrical structure, in normal valves, could be based on Golden Proportion, Fractals and Fibonacci Series. In the last decades, medical imaging devices, computers and software power have undergone an extremely fast and impressive improvement, making this amount of measurements ever bigger and more accurate. For this purpose, the most important information obtainable from imaging techniques consists of a huge amount of measurements, which allow us to describe and quantify with precision structure and function of the valve. Imaging techniques, mainly echocardiography, are the best available tool for assessing both the structure and the function of the Mitral Valve.Įvaluating valve disease, planning a repair strategy, monitoring the effects, during of immediately after the procedure, and carrying out the follow-up are the routine taken steps. When planning mitral repair, a deep and extremely accurate valve analysis is mandatory, particularly when an interventional technique is chosen, where a direct anatomical evaluation is impossible. Particularly, this new kind of interventions is rapidly growing, due to the ever better knowledge of valve anatomy and function, as well as to the impressive improvement occurred in the last years to medical devices, software, materials and engineering techniques. Originally based on conventional on-pump surgery, in the last years it has been integrated by several either off-pump or trans-catheter procedures. KeywordsĬonservative treatment is nowadays the routine choice to approach a diseased Mitral Valve. Published data and normality ranges have been compared with the values obtained from the 3D model, showing how it seems to produce the same results and give them a logical interpretation. Such a model, with the use of very simple calculations, can describe every geometrical reference of the Mitral Valve and seems to predict their expected normal values.Īfter a brief summary about the results of our previous research, we have reviewed literature concerning the most common geometrical references retrievable from imaging and currently employed to evaluate the Mitral Valve. In two recently published papers, we hypothesized that the healthy Mitral Valve could have a geometrical structure based on Golden Ratio, Fibonacci Series and Fractals, a scalar 3D model where all components are related one another by defined proportions and fit together like the pieces of a puzzle. In this scenario, an accurate geometrical analysis of the whole valve is actually mandatory, particularly when a hybrid or percutaneous approach is chosen and imaging is the only available eye. Similarly, both repair techniques and devices have undergone a consistent improvement in the last years, adding to traditional surgery a wide series of percutaneous and hybrid procedures. Therefore, the routine measurements now obtainable from the different imaging techniques allow an extensive and deep spatial evaluation of valve geometry. ![]() In the last decades, the number and the precision of these references have widely grown, due to a significant amount of research, as well as to a rapid empowering of imaging software and devices. Geometrical references are fundamental to perform a correct evaluation on a diseased valve, to plan the best repair strategy and to assess its results, both during the procedure and at follow-up. Nowadays, the procedure of choice to manage a diseased Mitral Valve is represented by conservative treatment.
