Plástica da valva mitral em pacientes consecutivos. Como é a evolução tardia?: avaliação clínica e ecocardiográfica

Avaliação cardiológica tardia de crianças com insuficiência mitral reumática, submetidas a cirurgia reconstrutora com anel de Gregori

“…From that time on, however, the indication for surgery was made based on the results from the Doppler echocardiogram, as well as on clinical parameters. There are several studies correlating Doppler echocardiographic studies with the results of mitral valvoplasty 16,19,22,[24][25][26][27][28][29] . According to the results achieved by Spencer et al 24 , from a total of 95 patients who were followed, 82 did not have regurgitation, whereas 12 had mild regurgitation.…”

“…The presence of a mild or moderate regurgitation is very common during the postoperative phase of mitral valvoplasty, as described by some authors 16,19,[22][23][24][25][26]29 , and the late clinical evolution is always satisfactory. Fix et al 28 conducted a pioneer study comparing the late evolution of patients who were classifi ed as having regurgitation intensity of I or II (76 patients).…”

“…Thromboembolic complications in the mechanical prostheses, as well as ruptures, restenoses and calcifications in the bioprostheses, are the major causes of morbidity and mortality in patients undergoing valvar replacement. This shows that, despite the great technological evolution and constant studies, an ideal substitute for the natural valve, either mechanical or biological, providing longevity and low thrombogenicity, is yet to be found [1][2][3][4][5] . Because of that, conservative techniques have been progressively used in patients with valvopathies in a number of centers [2][3][4][5][6] .…”

Because of that, conservative techniques have been progressively used in patients with valvopathies in a number of centers [2][3][4][5][6] . Thus, the interest in the morphology of cardiac valves, which during the 60's and 70's was limited to the pathological features due to the large number of valvar replacements, was extended.…”

“…In these cases, strips of synthetic materials such as Teflon, Dacron and polytetrafluoroethylene (PTFE) are applied to the posterior annulus, guiding the posterior cusps to the anterior cusp (Kay et al [10], Pomerantzeff et al [16], Salati et al [17], Barbosa et al [18]), as well as Hendren et al [19] who uses bovine pericardium to substitute the synthetic materials.…”
