“…In the present study, transesophageal echocardiography was used in most of the patients (68.3%) during the surgical procedure. Also, we observed improved regurgitation in 94.6%, a result similar to that of other Brazilian studies 16,18 .…”

“…Annuloplasty was the single procedure used in only eight of the patients studied (20%), thus demonstrating that in most of the cases (80%) the association with more than one technique was necessary, and in many occasions with modifications of the initial planning, a situation that has also been described by other authors 6,10,16 . Mitral annulus dilatation is present in almost all patients with mitral regurgitation.…”

“…Reoperation rates range from 8% to 10% 7,18 . Additionally, the outcomes also depend on the status of the valve at the moment of reconstruction, that is, the more severely it is damaged, the worse the outcome 16 . Gillinov et al reported reoperation-free survival in 93% after 10 years 22 ; the reason for the need of a new surgery was new bouts of rheumatic fever in most of the patients.…”

“…In Machado et al 18 case series, 72.6% of the cases were free from reoperation after 188 months. The major causes of failure in rheumatic mitral repair are wrong indications, use of inadequate techniques, and progression of the rheumatic valve disease 7,16 .…”

“…The reduction technique of the annulus in its entire length with small strips of bovine pericardium, intermittently, has two purposes, namely: to maintain the geometry of the annulus with its original characteristics and allow for growth -purposes that would not be achieved if the repair was performed using another approach, because the ring entirely non-biodegradable rigid or flexible maintains appropriate annular geometry, but such type of ring does not allow growth. Segmental rings for repair of the posterior portion of the annulus present good surgical outcomes [24,25], but allow growth only of the anterior portion, which can lead to a situation of geometrical misfit over time. Mitral repair through techniques that use bovine pericardium should provide bridging, in order to allow growth.…”

Objective: Mitral valve insufficiency must be treated by repair whenever as prossible as it provides better resultsespecially within the pediatric population in order to avoid valve replacement incovenients. The aim of this study is to describe mitral valve repair technique based on an anatomical and functional approach.Methods: During a 13 months period, eight children (age ranged from 2 and 12 years old 6.37 +\3.66) with mitral valve insufficiency underwent intermittent anterior and posterior annuloplasty associated with Alfieri's repair -performed by placing a stitch between the anterior and posterior leaflets in the point of maximal regurgitation thus creating a double orificial mitral valve.Results: There were no surgical deaths. All patients underwent postoperative echocardiography. Three patients showed mild insufficiency and five patients showed no insufficiency. The time in intensive care unit ranged from 2 to 4 days (2.5 + 0.75), and the time of stay in hospital ranged from 5 to 8 days (6.37 + 1.06).Conclusion: In spite of the little sample size, the proposed technique proved itself to be simple and effective in the treatment of single mitral valve insufficiency within the pediatric population. In addition, it also yielded satisfactory immediate results. Long-term follow-up is nevertheless necessary in order to evaluate long-term results.Descriptors: Heart defects,congenital. Child.

ResumoObjetivo: A insuficiência mitral com indicação cirúrgica na faixa etária pediátrica deve ser tratada por meio de plastia sempre que possível, evitando-se os inconvenientes da substituição valvar. O objetivo deste trabalho é propor técnica de plastia mitral baseada em abordagem funcional e anatômica.

PURPOSE: Prosthetic annuloplasty rings are currently used in mitral reconstruction. Posterior annuloplasty with a bovine pericardial strip is a technique largely used in the Heart Institute of University of São Paulo Medical School. The purpose of the study was to analyze the late results of mitral valve repair with posterior annuloplasty using a bovine pericardial strip. METHODS: Between January 1984 and December 2002, 273 patients underwent mitral valve repair with posterior pericardial annuloplasty in the Heart Institute of University of São Paulo Medical School. One hundred and forty four (52.7%) were women and ages ranged between 1 and 76 years (38.3 ± 21.1). Rheumatic fever was present in 52.0% of the patients. Associated techniques were employed in 26.0% of the patients, and the most frequent was chordal shortening (9.2%). RESULTS: Hospital mortality was 3.3% (9 patients), with the major cause being low cardiac output (6 patients). Actuarial survival was 55.1% ± 16.8% in 18 years. During the 18-year follow-up: patients were free from the following: reoperation (59.1% ±± 13.9%, (percent +/-Standard Error), thromboembolism (97.4% ± 2.3%), hemolysis (99.2% ± 0.2%), and endocarditis (99.6% ± 1.0%). In the late follow-up period, 83.9% were classified as New York Heart Association functional class I. CONCLUSIONS: Late results with mitral valve repair with posterior annuloplasty using a bovine pericardial strip were satisfactory. The technique is feasible, reproducible, and cost effective.
