“…Guedes et al14 describe a technique and results of mitral valve treatment by right anterolateral thoracotomy using aortic cannulation for cardiac pulmonary bypass and claim it is a simple, safe, and reproducible technique. Guedes et al15 also analyzed cardiac morphology and function using real time tridimensional echocardiography in individuals submitted to mitral valve repair with Double Teflon technique. They describe a left atrial and ventricle reverse remodeling associated with an improvement in left atrial function during the study.…”

Recent original scientific contributions published in selected Brazilian periodicals and classifiable under cardiovascular and pulmonary subject categories cover a wide range of sub specialties, both clinical and exprimental. Because they appear in journals with only recently enhanced visibility, we have decided to highlight a number of specific items appeared in four Brazilian journals, because we understand that this is an important subsidy to keep our readership adequately informed. These papers cover extensive sub-areas in both fields.

“…We conducted a subgroup analysis to evaluate whether the presence of atrial fibrillation might have had an impact on the results found from this study. We did not observe any significant alterations to the behavior of the variables evaluated over the course of the study, thus demonstration that the mitral valvuloplasty modified the ring measurements in a stable manner and also enabled reverse atrial and ventricular remodeling, independent of atrial fibrillation [ 25 ] . It is possible that the patients who persisted with atrial fibrillation over the course of time presented differences not in relation to behavior but, rather, in relation to the magnitude of the remodeling.…”

IntroductionMitral valve repair is the treatment of choice to correct mitral insufficiency, although the literature related to mitral valve annulus behavior after mitral repair without use of prosthetic rings is scarce.ObjectiveTo analyze mitral annulus morphology and function using real time tridimensional echocardiography in individuals submitted to mitral valve repair with Double Teflon technique.MethodsFourteen patients with mitral valve insufficiency secondary to mixomatous degeneration that were submitted to mitral valve repair with the Double Teflon technique were included. Thirteen patients were in FC III/IV. Patients were evaluated in preoperative period, immediate postoperative period, 6 months and 1 year after mitral repair. Statistical analysis was made by repeated measures ANOVA test and was considered statistically significant P<0.05.ResultsThere were no deaths, reoperation due to valve dysfunction, thromboembolism or endocarditis during the study. Posterior mitral annulus demonstrated a significant reduction in immediate postoperative period (P<0.001), remaining stable during the study, and presents a mean of reduction of 25.8% comparing with preoperative period. There was a significant reduction in anteroposterior and mediolateral diameters in the immediate postoperative period (P<0.001), although there was a significant increase in mediolateral diameter between immediate postoperative period and 1 year. There was no difference in mitral internal area variation over the cardiac cycle during the study.ConclusionSegmentar annuloplasty reduced the posterior component of mitral annulus, which remained stable in a 1-year-period. The variation in mitral annulus area during cardiac cycle remained stable during the study.

Mitral valve insufficiency is frequently the result of elongated or ruptured chordae tendineae. Several techniques have been described for its correction. However, when there is a severe elongation or rupture of the chordae, the most widely accepted treatment option has been valve replacement. The best long-term outcomes observed in conservative surgeries led us to choose this procedure rather than the correction of mitral valve insufficiency. We described three techniques for correction of mitral prolapse due to elongated and/or ruptured chordae tendineae. In addition, we developed mold pre built bovine pericardial chords (Braile-Gregori prosthesis) for chordae replacement. Finally, since 1987, the rigid prosthetic semicircular ring (Gregori-Braile ring) has been consistently used in our centre for correction of the posterior dilation of mitral annulus preferably in its portion close to the posteromedial commissure. Descriptors: Mitral valve/surgery. Mitral valve insufficiency. ResumoA insuficiência mitral é frequentemente resultado do alongamento ou ruptura das cordas tendíneas. Várias técnicas foram descritas para sua correção. Entretanto, quando o comprometimento das cordas é mais intenso, a substituição valvar tem sido mais usualmente empregada. Os bons resultados a longo prazo observados na cirurgia conservadora têm nos levado a eleger esse procedimento como prioridade. Três técnicas foram por nós desenvolvidas para correção de alongamento e/ou ruptura de cordas tendíneas. Além disso, desenvolvemos uma prótese de pericárdio bovino para a substituição de cordas (prótese Braile-Gregori). Finalmente, desde 1987 empregamos o anel rígido semicircular (anel GregoriBraile) para a correção do alongamento posterior do anel mitral, com ênfase na sua porção junto à comissura póstero-medial.
