The aim of this study was to characterize morphological variability of the mitral valve leaflets and to provide the size of their particular parts. Materials and Methods: In the study, we included 200 autopsied human hearts from Caucasian individuals (25% females) with mean age 47.5 (卤17.9) without any valvular diseases. The morphology of the mitral valve was evaluated. The intercommissural and aorto-mural diameters of the mitral annulus were measured. All leaflets and their scallops were identified. The base and the height of the posteromedial commissure (PM-C), anterolateral commissure (AL-C), anterior leaflet (AL) and posterior leaflet (PL) with their scallops were measured. Results: The intercommissural diameter was 28.0卤4.8 mm, the aorto-mural diameter 19.7卤4.8 mm, circumference of the mitral annulus 89.9卤12.6 mm and the area of the mitral valve 485.4卤171.4 mm2. Classical mitral valves (AL+AL-C+PL(P1,P2,P3)+PM-C) were found in 141 (70.5%) specimens. In classical type, the mean AL base and height were 30.8卤4.9 mm and 20.6卤4.2 mm, while mean PL base and height 45.1卤8.2 mm 12.9卤2.8 mm respectively. The mean ratio of the AL base to PL base was 0.7卤0.2. Variations in PL were found in 55 (27.5%) and in AL in 5 (2.5%) hearts. The most common variations were: valve with one accessory scallop (AcS) between P3 and PM-C (7%); AcS between P1 and AL-C (4%); connections of P2 and P3 scallops (4%); connections of P1 and P2 scallops (3%); AcS in AL (2.5%). All AcS were smaller than the main PL scallops. The mean intertrigonal distance was 21.9卤3.8 mm. Conclusions: In all cases, the mitral valve is built by two main leaflets with possible variants in secondary to leaflets scallops (29.5%). The variations are largely associated with PL and are mostly related to the presence of AcS. Anatomically the AL is not divided into scallops, and it occupies 34.5% of the mitral annulus circumference. Understanding the anatomy of the mitral valve leaflets helps to planning and performing mitral valve repair procedures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accessory%20scallop" title="accessory scallop">accessory scallop</a>, <a href="https://publications.waset.org/abstracts/search?q=commissure" title=" commissure"> commissure</a>, <a href="https://publications.waset.org/abstracts/search?q=connected%20%20scallops" title=" connected scallops"> connected scallops</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20heart" title=" human heart"> human heart</a>, <a href="https://publications.waset.org/abstracts/search?q=mitral%20leaflets" title=" mitral leaflets"> mitral leaflets</a>, <a href="https://publications.waset.org/abstracts/search?q=mitral%20valve" title=" mitral valve"> mitral valve</a> </p> <a href="https://publications.waset.org/abstracts/65755/anatomy-of-the-human-mitral-valve-leaflets-implications-for-transcatheter-and-surgical-mitral-valve-repair-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65755.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">389</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Craniopharyngiomas: Surgical Techniques: The Combined Interhemispheric Sub-Commissural Translaminaterminalis Approach to Tumors in and Around the Third Ventricle: Neurological and Functional Outcome</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pietro%20Mortini">Pietro Mortini</a>, <a href="https://publications.waset.org/abstracts/search?q=Marco%20Losa"> Marco Losa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: Resection of large lesions growing into the third ventricle remains a demanding surgery, sometimes at risk of severe post-operative complications. Transcallosal and transcortical routes were considered as approaches of choice to access the third ventricle, however neurological consequences like memory loss have been reported. We report clinical results of the previously described combined interhemispheric sub-commissural translaminaterminalis approach (CISTA) for the resection of large lesions located in the third ventricle. Methods: Authors conducted a retrospective analysis on 10 patients, who were operated through the CISTA, for the resection of lesions growing into the third ventricle. Results: Total resection was achieved in all cases. Cognitive worsening occurred only in one case. No perioperative deaths were recorded and, at last follow-up, all patients were alive. One year after surgery 80% of patients had an excellent outcome with a KPS 100 and Glasgow Outcome score (GOS) Conclusion: The CISTA represents a safe and effective alternative to transcallosal and transcortical routes to resect lesions growing into the third ventricle. It allows for a multiangle trajectory to access the third ventricle with a wide working area free from critical neurovascular structures, without any section of the corpus callosum, the anterior commissure and the fornix. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=craniopharingioma"
