    Left Atrium Reverse Remodeling in Patients With Mitral Valve Stenosis After Percutaneous Valvuloplasty: A 2-and 3-Dimensional Echocardiographic Study
    (2013) VIEIRA, Marcelo L. Campos; SILVA, Murilo C.; WAGNER, Camila R.; DALLAN, Luis A.; KAJITA, Luis J.; OLIVEIRA, Wercules A.; SAMESINA, Nelson; HOTTA, Viviane T.; MATHIAS JR., Wilson; SPINA, Guilherme; CARDOSO, Luis; PASTORE, Carlos A.; TARASOUTCHI, Flavio; GRINBERG, Max
    Introduction and objectives: The left atrium is clinically relevant in patients with mitral valve stenosis. The objective of this study was to analyze the effects of percutaneous balloon valvuloplasty on left atrium volumes and the left atrium emptying fraction in symptomatic mitral valve stenosis patients using 2-dimensional and real-time 3 -dimensional transthoracic echocardiography. Methods: We carried out a prospective study of 28 consecutive symptomatic mitral valve stenosis patients, aged 22-72 (39 [11.5]) years, 24/28 (85.6%) women, who underwent to percutaneous balloon valvuloplasty between March 2009 and May 2011. Patients underwent 2- and 3-dimensional transthoracic and transesophageal echocardiography (atrial fibrillation) and invasive mitral valve area measurement. Echocardiographic analysis was performed before, 72 h after and 12 months after percutaneous balloon valvuloplasty. The following parameters were analyzed: a) mitral valve area (2-dimensional planimetry, pressure half-time, 3-dimensional echocardiography, invasive hemodynamic measurement); b) indexed left atrium maximum and indexed minimum volumes, and c) left atrium emptying fraction. Results: The 3-dimensional parameters of the mitral valve stenosis patients before and 72 h and 12 months after percutaneous balloon valvuloplasty were as follows: a) mitral valve area: 0.9 (0.1) cm(2); 1.8 (0.2) cm(2) (P<.001); 1.7 (0.2) cm(2) (P<.001); b) left atrium maximum volumes: 49.9 (12) mL/m(2); 42 (11.4) mL/m(2) (P<.001); 40.3 (10.2) mL/m(2)(P<.001), and c) left atrium emptying fraction: 30.1 (9.4%); 40.6 (7.4%) (P<.001); 44.1 (8%) (P<.001), respectively. Conclusions: In symptomatic mitral valve stenosis patients who underwent percutaneous balloon valvuloplasty analysis by 2- and 3-dimensional echocardiography, improvements in left atrium reverse remodeling and left atrium emptying fraction were observed 72 h and 12 months after the procedure.
