Atrial Function as a Guide to Timing of Intervention in Mitral Valve Prolapse With Mitral Regurgitation

Abstract: We report the changes in left atrial function in humans with MVP and the relationship of LA dysfunction to clinical indications for mitral valve surgery. We propose that the findings support the utility of quantitative assessment of atrial function by echocardiography as an additional tool to guide the optimum timing of surgery for MVP.

“…In mitral valve prolapse, loss of atrial contractile function in atrial fibrillation clearly impacts upon prognosis 15,16 . We have previously examined patients with MR with or without conventional indications for surgical intervention and demonstrated that impaired LA functional indices correspond to accepted adverse prognostic findings in MVP 18 . The current study expands upon our previous work: we wished to determine whether the analysis of LA function could help identify individuals without conventional guideline-based indications for surgical intervention in whom clinical or echocardiographic deterioration occurs sooner during follow-up, thereby potentially allowing identification of the optimal window for intervention in MVP.…”

“…В исследованиях последних лет была доказа-тельно установлена роль ФП и связанных с ней ремоделирований левого предсердия, дилатации клапанного кольца в развитии значимой пред-сердной митральной регургитации [6,10,11,12]. Так, L. Ring et al в 2013 г. на основании данных 3D-эхокардиографии с помощью линейного ре-грессионного анализа установили сильную не-зависимую ассоциацию объема левого предсер-дия с площадью митрального отверстия у боль-ных с ФП и тем самым показали, что дилатация митрального клапанного кольца тесно связана с дилатацией полости левого предсердия и явля-ется одним из механизмов развития функцио-нальной МР при ФП [12].…”

“…Leaf atrial strain during reservoir phase has been univocally defined as a strong predictor of LA reverse remodeling in patients undergoing surgery for severe MR. 31 The assessment of LA function provides an insight of the histopathological changes that occur in this chamber as the disease progresses, 32 since LASr is strongly inverse correlated with atrial fibrosis in severe MR. 33 In patients with chronic MR, LASr, which reflects LA compliance, is strongly influenced by the severity of the defect, reflecting its ability to express the worsening of MR and to be an indirect index of its duration. Indeed, in patients with mild MR, LASr appears to be higher than the normal value, following the Frank-Starling model (the mild increase in blood volume that arrives to LA increases LA contractility), whereas a highly depressed value characterizes severe MR 34 (Figure 3).…”
