“…They used saline test to examine adjustment of neo-chordal length. Tam et al used a caliper during the surgery to measure the length of neochordae ( 10 ). Gillinov improved their methods and measured the length of neochordae with a caliper and made the loops around it ( 11 ).…”

Background:Mitral valve repair has shown superior results compared to mitral valve replacement in patients with mitral valve prolapse. Using premeasured neochordae (the loop technique) has been proposed for both anterior and posterior leaflet repairs. However, there are two major problems that are usually experienced using this method. One is deciding the length of the neo-chordae, and the other is tying the knot at the intended length.Objectives:This study introduced a new technology in mitral valve repair that reduces the complexity of making neo-chordae loops, especially in minimally invasive surgeries.Patients and Methods:Neochordameter is a new device which utilizes preoperative transthoracic echocardiography to determine the exact length of required neochordae and enable surgeons to make neochordae loops before starting the cardiopulmonary bypass. In this study, we applied this technique in mitral valve repair of three patients.Results:Two of these patients were male and the other one was female. All of them had severe mitral regurgitation requiring anterior leaflet repair. Total eight neochordae loops were used in these patients. No change in the length of neochordae was required after saline test and all of these patients had none or trivial mitral regurgitation by intraoperative and follow up transesophageal echocardiography. No complication was seen in six-month follow up.Conclusions:The ability of this technology in developing premeasured neo-chordae loops with accurate sizes and not needing the post-implantation length adjustment which is efficient in reducing the complexity of both minimally invasive and conventional surgeries are the issues which is going to be regarded .

“…A simplified technique for multiple cord placements for the entire cordal apparatus has been described for mitral valve repair. 3,4 In reconstruction of the TV, however, one has to account for distension of the right ventricle during reconstruction of the TV, especially in patients with dilated right ventricles. Thus polytetrafluoroethylene neocords need to be sized individually (Figure 2, A-E).…”

Киевская, 111аCardiology Research Institute, Tomsk National Research Medical Center, Russian Academy of Sciences, 111а, Kievskaya str., Тоmsk, 634012, Russian Federation В данной статье приводится обзор современных методик лечения пролапса митрального клапана вследствие деге-нерации. Медикаментозное лечение пациентов с пролапсом митрального клапана малоэффективно. Предпочтение в данном случае следует отдать хирургическому лечению. Показано, что при выборе тактики вмешательства важно учитывать не только наличие самой патологии, но и исходное функциональное состояние элементов подклапан-ного аппарата. Так, среди методов хирургического лечения протезирование клапана при данной патологии имеет значительные недостатки по сравнению с реконструктивной хирургией. Показано разнообразие техник пластики митрального клапана. Представлены преимущества и недостатки каждого из методов. Ключевые слова: хирургическое лечение пролапса митрального клапана, разнообразие техник пластики ми-трального клапана Конфликт интересов: авторы заявляют об отсутствии конфликта интересов Прозрачность финансовой деятельности: никто из авторов не имеет финансовой заинтересованности в представленных материалах или методах Для цитирования: Макогончук И.

DOI: 10.29001/2073DOI: 10.29001/ -8552-2018 This article provides an overview of modern methods of treating prolapse of the mitral valve due to degeneration. Medical treatment of patients with mitral valve prolapse is ineffective. Preference in this case should be given to the surgical treatment. It is shown that while choosing tactics of intervention it is important to take into account not only the presence of the pathology itself, but also the initial functional state of the elements of the subvalvular apparatus. So, among the methods of surgical treatment, valve prosthesis in this pathology has significant disadvantages in comparison with reconstructive surgery. A variety of techniques for mitral valve plastic are shown. The advantages and disadvantages of each method are presented.
