“…Keywords: mitral valve prolapse, poor prognosis. Прогноз пациентов с пролапсом митрального клапана (ПМК) при всем многообразии проявлений, обусловленных вовлечением соеди нительнотканных нарушений различных органов и систем, определяют в основном сердечно-сосудистые осложнения -прогрессирование митральной регургитации (МР) и развитие сердечной недостаточности, нарушения ритма сердца, инфекционный эндокардит, церебральные эмболии, риск внезапной смерти [1][2][3]. Динамика ПМК у некоторых пациентов в течение нескольких лет характеризуется прогрессирующим течением патологии с ремоделированием камер сердца, увеличением частоты и сложности аритмий, другими осложнениями [4].…”

“…Для соединительнотканной дисплазии митрального клапана с выраженной миксоматозной трансформацией створок характерно развитие таких осложнений, как: отрыв хорд, тяжелая клапанная регургитация, развитие инфекционного эндокардита, высокая вероятность перфорации створок [3,6]. В данном исследовании в подавляющем большинстве случаев указанные осложнения отмечались в 1-й группе.…”

Aim. Study of the fnctional state of left ventricular myocardium and determination of diagnostic criteria of poor prognosis of mitral valve prolapse. Methods. 151 patients (116 males and 35 females) with mitral valve prolapse (MVP) were examined. The average age was 34.8 ± 0.79 years. Division by the groups was performed depending on the severity of structural changes of the valve and width of the cusps: group 1 included 54 patients with classic form of MVP (cusp width ≥5 mm), group 2 included 55 patients with cusp width ≥3 mm, group 3 included 42 patients with MV cusp width less than 3 mm. All patients underwent complex clinical functional examination of cardiovascular system. The state of systolic and diastolic cardiac function was assessed using stationary high-tech ultrasound scanner «Philips iE-33» (Philips, Holland) according to conventional technique with determination of standard heart parameters and calculation of intracardiac hemodynamic parameters. Echocardiography was performed on admission and 12 to 18 month later. Results. The study revealed that the most prominent changes of cardiohemodynamics and unfavorable disease course were observed in 72.2 % of patients with classic form of MVP (group 1). Patients with non-classic form of MVP (group 2) also had poor prognosis in 27.8 % of cases. Diagnostic criteria of poor prognosis of MVP according to echocardiography were determined: severe mitral regurgitation (degree ≥III), mitral valve cusp thickness during diastole over 6 mm, left ventricle dilation (EDS ≥ 60 mm; ESS ≥ 36 mm), left atrial dilation (anterior posterior size of LA ≥ 40 mm, LA volume ≥ 80 ml), mitral annulus dilation (diameter of MA ≥ 35 mm). Conclusion. Differences of functional state of the myocardium of left ventricle were revealed depending on the type of mitral valve prolapse caused by the severity of connective tissue dysplasia. In classic form of MVP more severe disorders of intracardiac hemodynamics were observed as well as more severe mitral insufficiency.

View full text Add to dashboard Cite

The problem of the mitral valve (MV) dysfunction, both in isolation and combination forms with other anomalies and lesions of connective tissue structures, is very current. Mitral insufficiency (MI) in case of the connective tissue dysplasia is the most common valvular pathology, accompanied by different degrees of severity. Nowadays the progradient development of functional and clinical symptoms of this disease has been studied, the questions of epidemiology, diagnosis and prognosis have been clarified and reconsidered. There are important issues of correct diagnosis, time and method of treatment, the decision of usage a valve-repair or valve prosthesis in the certain clinical situation. All these practical algorithm steps depend on the clinical and surgical experience of the medical institutions which work with this pathology. The purpose of this article is to expand the knowledge of practical doctors in the issue of MI in case of connective tissue dysplasia, including the questions from the model of the MV structure to modern methods of treatment which are described in the contemporary literature.

Objective: To present the first-hand results of a modified mitral annuloplasty (MA) with an autopericardial strip (APS) in degenerative mitral valve disease (DMVD). Methods: Fifty-three patients with DMVD (mean age, 54.9±9.5 years (36-78 years); n=32 men (60.4%) and n=21women (39.6%)) undergoing MA with an APS, between January 2017 and January 2020 were retrospectively studied. In the overwhelming majority of cases, triangular and quadrangular resections of the P2 segment were performed. In addition, in some cases, neochords were implanted to the A2 segment. Intraoperatively, the result of MA was considered satisfactory if, according to transoesophageal echocardiography, the degree of mitral regurgitation (MR) did not exceed grade 1. Results: No in-hospital mortality was observed. One female patient had an early relapse caused by the rupture of one of the neochords at the A2 segment. However, the MR did not exceed grade 2, and the patient was actively followed up. Conclusion: Individual APS length selection avoids overcorrecting and achieves adequate systolic and diastolic mitral valve performance. Keywords: Annuloplasty, mitral regurgitation, autopericardium, mitral regurgitation.
