RESUMO
Abstract Introduction: Cardiovascular disease is an important cause of death among patients with chronic kidney disease (CKD). Valve calcification is a predictor of cardiovascular mortality and coronary artery disease. Objective: To assess heart valve disease frequency, associated factors, and progression in CKD patients. Methods: We conducted a retrospective study on 291 CKD patients at Hospital das Clínicas de Pernambuco. Inclusion criteria were age ≥ 18 with CKD and valve disease, while those on conservative management or with missing data were excluded. Clinical and laboratory variables were compared, and patients were categorized by dialysis duration (<5 years; 5-10 years; >10 years). Statistical tests, including chi-square, Fisher's exact, ANOVA, and Kruskal-Wallis, were employed as needed. Simple and multivariate binary regression models were used to analyze valve disease associations with dialysis duration. Significance was defined as p < 0.05. Results: Mitral valve disease was present in 82.5% (240) of patients, followed by aortic valve disease (65.6%; 86). Over time, 106 (36.4%) patients developed valve disease. No significant association was found between aortic, pulmonary, mitral, or tricuspid valve disease and dialysis duration. Secondary hyperparathyroidism was the sole statistically significant factor for mitral valve disease in the regression model (OR 2.59 [95% CI: 1.09-6.18]; p = 0.031). Conclusion: CKD patients on renal replacement therapy exhibit a high frequency of valve disease, particularly mitral and aortic valve disease. However, no link was established between dialysis duration and valve disease occurrence or progression.
Resumo Introdução: Doenças cardiovasculares são uma causa significativa de morte em pacientes com Doença Renal Crônica (DRC). A calcificação valvar é preditor de mortalidade cardiovascular e doença arterial coronariana. Objetivo: Avaliar a frequência, fatores associados e progressão de valvopatias em pacientes com DRC. Métodos: Coorte retrospectiva com 291 pacientes ambulatoriais no Hospital das Clínicas de Pernambuco. Inclusão: ≥18 anos com DRC e valvopatia; exclusão: tratamento conservador ou dados incompletos. Variáveis clínicas e laboratoriais foram comparadas e categorizadas por tempo de terapia dialítica (TTD): <5 anos, 5-10 anos, >10 anos. Foram aplicados os testes Qui-quadrado, exato de Fisher, ANOVA, Kruskal-Wallis. Associação entre valvopatia e TTD foi avaliada por regressão binária. Significância foi definida como p < 0,05. Resultados: A valvopatia mitral foi encontrada em 82,5% (240) dos casos, seguida da aórtica (65,6%; 86). Houve progressão da doença valvar em 106 (36,4%) pacientes. Não houve associação entre valvopatias aórtica, pulmonar, mitral ou tricúspide e TTD. Hiperparatireoidismo secundário foi a única variável explicativa significativa na regressão para valvopatia mitral (OR 2,59 [IC95%: 1,09-6,18]; p = 0,031). Conclusão: Encontramos alta frequência de valvopatias, especialmente mitral e aórtica, aem pacientes com DRC. Não houve associação entre TTD e valvopatia.
RESUMO
Infective endocarditis (IE) is an infection of the inner lining of the heart, especially the heart valves, and carries high morbidity and mortality. It can manifest itself acutely or subacutely, the latter being more insidious. Diagnosis is challenging, especially in early stages, requiring high clinical suspicion using modified Duke criteria. Treatment involves antimicrobials and in certain cases cardiac surgery is essential. The clinical case presents a patient with a history of aortic valve replacement, who develops acute symptoms. Although the diagnosis of endocarditis is achieved, a por physical examination delays starting optimal treatment. Early diagnosis is crucial to avoid adverse outcomes. Post-hospital discharge follow-up is essential to identify possible long-term complications.
La endocarditis infecciosa es una infección del revestimiento interno del corazón, especialmente de las válvulas cardíacas, con alta morbimortalidad. Se manifiesta como aguda o subaguda, siendo esta última más insidiosa. El diagnóstico es desafiante, especialmente en etapas tempranas, requiriendo sospecha clínica en pacientes con fiebre, factores de riesgo cardiacos o no cardiacos y el uso de los criterios de Duke- International Society of Cardiovascular Infectious Diseases. El tratamiento implica antimicrobianos y en ciertos casos es imprescindible la cirugía cardiaca. Se presenta un caso clínico de un paciente con antecedentes de reemplazo valvular aórtico, que desarrolla síntomas agudos. Aunque se logra el diagnóstico de endocarditis, un examen físico poco exhaustivo causa retraso en el inicio del tratamiento óptimo. Un diagnóstico temprano es crucial para evitar resultados adversos. Es esencial la vigilancia estrecha post alta hospitalaria debido a complicaciones a largo plazo.

Resumen En Costa Rica, el Reglamento de la Autopsia Hospitalaria y Médico Legal establece que la autopsia médico legal es obligatoria para toda muerte súbita. La patología cardíaca es responsable aproximadamente del 80 % de las muertes súbitas que requieren una autopsia forense; el prolapso de la válvula mitral (degeneración mixomatosa de la válvula mitral) es una de las formas más comunes de valvulopatía cardíaca, es relativamente común (2%-3% de la población general), y a menudo se considera benigno, la tasa anual de muerte cardíaca súbita (MSC) en individuos con MVP (0,2%-0,4% /año) es aproximadamente el doble que el observado en la población general (0,1%-0,2% año).
Abstract In Costa Rica, the Hospital and Legal Autopsy Regulations establish that a legal medical autopsy is mandatory for all sudden deaths. Cardiac pathology is responsible for approximately 80% of sudden deaths requiring a forensic autopsy; Mitral valve prolapse (myxomatous mitral valve degeneration) is one of the most common forms of heart valve disease, is relatively common (2%-3% of the general population), and is often considered benign, the annual rate of Sudden cardiac death (SCD) in individuals with MVP (0.2%-0.4%/year) is approximately twice that observed in the general population (0.1%-0.2%/year).
RESUMO
ABSTRACT Introduction: Atrial fibrillation is one of the common complications of mitral valve disease. Currently, in the absence of freezing equipment, it's still impossible to fully conduct a minimally invasive Cox-maze IV procedure to treat atrial fibrillation. Methods: We analyzed the clinical data of 28 patients who underwent thoracoscopic minimally invasive mitral valve full maze surgery in our hospital from October 2021 to September 2022; 13 patients were male and 15 were female, three suffered from paroxysmal atrial fibrillation, and 25 suffered from permanent atrial fibrillation; average age was 61.88±8.30 years, and mean preoperative left atrial diameter was 47.12±8.34 mm. Isolation of left atrial posterior wall (box lesion) was completed in all patients by cut-and-sew technique and bipolar clamp ablation. Results: For these subjects, the median cardiopulmonary bypass time was 169 (109.75-202.75) minutes, aortic cross-clamping time was 106 (77.75-125.50) minutes, and ventilator assistance time was 6.5 (0-10) hours. Among them, eight subjects had the endotracheal tubes removed immediately after surgical operation. Three subjects were in the blanking period; two subjects still had atrial fibrillation at three months after operation, one of whom resumed sinus rhythm after electrical cardioversion therapy; and all the remaining 23 subjects had sinus rhythm. Conclusion: The minimally invasive cut-and-sew technique for electrical isolation of left pulmonary veins can improve sinus conversion rate of patients suffering from both mitral valve disease and atrial fibrillation. In selected subjects, it is safe and has good results in the short-term postoperative period.
RESUMO
ABSTRACT Introduction: There are few circulating biomarkers for valvular heart disease. Angiopoietin (Ang) 1, Ang2, and vascular endothelial growth factor are important inflammation-associated cytokines. The aim of this study was to investigate the clinical significance and association of Ang1, Ang2, and vascular endothelial growth factor in valvular heart disease. Methods: This is a retrospective study; a total of 62 individuals (valvular heart disease patients [n=42] and healthy controls [n=20]) were included. Plasma levels of Ang1, Ang2, and vascular endothelial growth factor were detected by enzyme-linked immunosorbent assays. We retrospectively collected the baseline characteristics and short-term outcomes; logistic regression was performed to identify predictor for short-term mortality. Results: Ang2 was significantly decreased in the valvular heart disease group compared with the healthy control group (P=0.023), while no significant difference was observed in the Ang1 and vascular endothelial growth factor levels. The Ang2 level of New York Heart Association (NYHA) I/II patients — but not NYHA III/IV patients — was significantly decreased compared with that of healthy control individuals (NYHA I/II: P=0.017; NYHA III/IV: P=0.485). Univariable logistic regression analysis indicated that Ang2 was a significant independent predictor for short-term mortality (odds ratio 18.75, P=0.033, 95% confidence interval 8.08-102.33). Ang1 was negatively correlated with Ang2 (P=0.032, Pearson's correlation coefficient =-0.317) and was positively correlated with vascular endothelial growth factor (P=0.019, Pearson's correlation coefficient = 0.359). Conclusion: Ang2 might serve as a therapeutic and prognostic target for valvular heart disease.
RESUMO
ABSTRACT The objectives of this article are to reflect on the rationale behind the use of echocardiographic screening for rheumatic heart disease and to provide key recommendations about steps needed to implement and improve echocardiographic screening programs in Latin America. Rheumatic heart disease remains a public health problem affecting mainly low-income and lower-middle-income countries and populations. Latin America is an area with economic inequalities, and the epidemiology of rheumatic heart disease remains largely unknown. Echocardiographic screening is useful for updating the epidemiology and providing early diagnosis of the disease. We discuss different approaches used in successful echocardiographic screening programs worldwide and in Latin America. We then identify the key elements needed to establish successful echocardiographic screening programs in Latin America, including increased awareness and involvement from multiple sectors (e.g. the community, health care professionals, scientific organizations and public health entities), identification of areas in need, development of a plan and structure that include different screening approaches, and how to ensure appropriate follow up for those who screen positive.
RESUMEN Los objetivos de este artículo son reflexionar sobre los fundamentos que justifican el uso del tamizaje ecocardiográfico para detectar la cardiopatía reumática y ofrecer algunas recomendaciones importantes sobre los pasos que habría que dar para poner en marcha programas de tamizaje ecocardiográfico y mejorar los existentes en América Latina. La cardiopatía reumática sigue siendo un problema de salud pública que afecta principalmente a países y grupos poblacionales de ingresos bajos y medianos bajos. América Latina es una región de grandes desigualdades económicas y las características epidemiológicas de la cardiopatía reumática siguen siendo desconocidas en gran medida. El tamizaje ecocardiográfico resulta útil para actualizar los datos epidemiológicos y posibilitar un diagnóstico temprano de la enfermedad. En este artículo se analizan los diferentes enfoques empleados en algunos programas de tamizaje ecocardiográfico eficaces de distintas partes del mundo, incluida América Latina. A continuación se determinan los elementos clave necesarios para establecer programas eficaces de tamizaje ecocardiográfico en América Latina, incluida una mayor concientización y participación de diversos sectores (p. ej., la comunidad, los profesionales de salud, las organizaciones científicas y las entidades de salud pública), la identificación de las zonas más necesitadas, la elaboración de un plan y una estructura que incluyan diferentes abordajes del tamizaje, y el modo de garantizar un seguimiento adecuado de aquellas personas con un resultado positivo en el tamizaje.
RESUMO Os objetivos deste artigo são oferecer observações sobre a fundamentação do uso da triagem ecocardiográfica para doença cardíaca reumática e fornecer recomendações importantes sobre as etapas necessárias para implementar e melhorar os programas de triagem ecocardiográfica na América Latina. A doença cardíaca reumática continua sendo um problema de saúde pública que afeta principalmente países e populações de renda baixa e média-baixa. A América Latina é uma área com desigualdades econômicas, e a epidemiologia da doença cardíaca reumática continua amplamente desconhecida. A triagem ecocardiográfica serve para atualizar a epidemiologia e proporcionar o diagnóstico precoce da doença. Examinamos as diferentes abordagens usadas em programas de triagem ecocardiográfica bem-sucedidos em todo o mundo e na América Latina. Em seguida, identificamos os principais elementos necessários para estabelecer programas de triagem ecocardiográfica com sucesso na América Latina. Tais programas incluiriam maior conscientização e envolvimento de vários setores (por exemplo, a comunidade, profissionais de saúde, organizações científicas e entidades de saúde pública), identificação de áreas carentes, desenvolvimento de um plano e estrutura abrangendo diferentes abordagens de triagem e formas de garantir o seguimento adequado de pessoas com resultado positivo na triagem.
RESUMO
El pectus excavatum (PEX) es una deformación de la pared torácica que obedece a una alteración de los cartílagos costales con el consiguiente hundimiento del esternón. Históricamente, se clasificaba como un defecto únicamente estético o cosmético, sin embargo, en los últimos años se han desarrollado nuevos métodos de estudio para la valoración de las repercusiones de esta patología. Existe cada vez más bibliografía que demuestra importantes repercusiones funcionales. Se realizó una puesta al día de las repercusiones cardíacas de la patología y un análisis de los artículos más relevantes de los últimos años. La evidencia actual permite afirmar que existe una afectación cardíaca por compresión esternal en la mayoría de los pacientes con PEX. Las afectaciones incluyen alteraciones anatomofuncionales (trastornos del ritmo, disminución del llenado ventricular), del volumen sistólico, aumento de la presión de la aurícula derecha, valvulopatías, compresión del ventrículo derecho, derrame pericárdico, entre otras. Todo lo cual permite concluir que el PEX puede presentar importantes alteraciones cardíacas que deben ser tenidas en cuenta a la hora de valorar los pacientes con esta patología.
Pectus excavatum (PEX) is a deformation of the chest wall caused by an alteration of the costal cartilages with the consequent collapse of the sternum. Historically, it had been classified as a solely aesthetic or cosmetic defect, however, in recent years new study methods have been developed to assess the repercussions of this pathology, with increasing bibliography showing important functional consequences. We updated the cardiac pathological repercussions and analyzed the most relevant articles of recent years. The current evidence suggests that there is cardiac involvement due to sternal compression in most patients with PEX. These affectations include anatomical functional alterations: rhythm disorders, decreased ventricular filling, decreased stroke volume, increased right atrial pressure, valve disease, right ventricular compression, pericardial effusion, among others. All of which enables us to conclude that PEX can present important cardiac alterations that must be taken into account when assessing patients with this pathology.
Pectus excavatum (PEX) é uma deformação da parede torácica decorrente de uma alteração das cartilagens costais com consequente colapso do esterno. Historicamente, foi classificado como um defeito exclusivamente estético ou cosmético, porém, nos últimos anos, novos métodos de estudo foram desenvolvidos para avaliar as repercussões dessa patologia, com crescente bibliografia mostrando importantes repercussões funcionais. Foi realizada uma atualização das repercussões cardíacas da patologia e análise dos artigos mais relevantes dos últimos anos. As evidências atuais permitem afirmar que há acometimento cardíaco por compressão esternal na maioria dos pacientes com PEX. As afecções incluem alterações anatomofuncionais: distúrbios do ritmo, diminuição do enchimento ventricular, diminuição do volume sistólico, aumento da pressão atrial direita, doença valvular, compressão do ventrículo direito, derrame pericárdico, entre outras. Tudo isso permite concluir que o PEX pode apresentar alterações cardíacas importantes que devem ser levadas em consideração na avaliação de pacientes com essa patologia.

ABSTRACT Introduction: The relationship between mitral annular calcification (MAC) and the controlling nutritional status (CONUT) score has not been previously studied. In this study, we investigated the relationship between MAC and CONUT score to evaluate the nutritional status of patients with MAC. Methods: A total of 275 patients, including 150 patients with MAC and 125 patients without MAC, who presented to a cardiology outpatient clinic were enrolled in the study. Results: There was no difference in the CONUT score between the two groups. Correlation analysis indicated that CONUT score was positively correlated with left atrial (LA) diameter (r=0.190, P=0.020) and interventricular septum thickness (r=0.179, P=0.028) in the MAC+ group. In multivariate regression analysis, only LA diameter (odds ratio 95% confidence interval = 1,054-1,189, P=0.0001) was independently associated with MAC. Conclusion: The present study investigated the relationship between CONUT score and MAC for the first time in the literature. We demonstrated that CONUT score was not significantly higher in patients with MAC without chronic diseases. However, CONUT score was correlated with LA diameter in patients with MAC. We therefore conclude that, for patients admitted with MAC and high LA diameter, CONUT is a valuable nutritional and inflammatory status index.
RESUMO
ABSTRACT Aortic valve repair combined with root stabilization procedures have been reported to have reliable mid to long-term outcomes, and this is one of the reasons that various surgical units are accepting these techniques as an option in selected cases. Aortic valve replacement is a standard procedure with established results, but to master its techniques there is a major uphill learning curve. A brief communication is presented on the aortic valve repair focusing on the lesser discussed aspects like global variability of the pathology and outcomes, variable referral patterns, and effect of ethnicity.
RESUMO
ABSTRACT Introduction: The totally thoracoscopic approach for mitral valve (MV) disease is a minimally invasive method. We investigated the procedure's feasibility, safety and effectiveness when it was performed by an experienced operator. Methods: We retrospectively analysed 96 consecutive patients with MV disease treated between March 2016 and November 2019 by minimally invasive procedures. The procedures were performed on a femoral artery-vein bypass through two ports, including a main operation port and a thoracoscopic port. The clinical data of patients were collected, including preoperative cardiac function, operative data, postoperative complications, and follow-up. Results: A total of 96 patients (57 male patients; average age, 49.7±14.5 years; left ventricular ejection fraction, 65.6±7.7%) were enrolled in this study. No intraoperative conversion incision or death occurred. The cardiopulmonary bypass and aortic cross-clamp times were 163.8±50.6 minutes and 119.7±38.9 minutes, respectively. Postoperative chest tube drainage in the first 24 hours was 232.8±108.1 ml. The ventilation time and length of intensive care unit stay were 13.2±6.2 hours and 2.9±2.2 days, respectively. One patient died of disseminated intravascular coagulation and prosthesis thrombosis 3 days after the operation, fearing anticoagulant-related hemorrhage. The overall success rate of valve repair during 1-year follow-up was 97.9%. Conclusion: The totally thoracoscopic procedure on mitral valves by an experienced surgeon is technically feasible, safe, effective and worthy of widespread adoption in clinical practice.
RESUMO
ABSTRACT Introduction: Aortic stenosis is the most common heart valve disease in the world, and patients that present with symptoms have a high mortality rate. Aortic valve replacement has the objective of promote left ventricular remodeling, reduce symptoms, and increase overall survival. The objective of this study is to evaluate reverse remodeling of the left ventricle in patients with severe and symptomatic aortic stenosis who underwent surgical or percutaneous transcatheter aortic valve replacement. Methods: This is a longitudinal, prospective, non-concurrent, non-randomized unicentric study with patients who underwent aortic valve replacement. Echocardiogram was performed before and after replacement procedure to evaluate several remodeling indexes. Results: Of 91 patients, 77 (84.6%) underwent surgical aortic valve replacement, and 14 (15.4%) underwent percutaneous transcatheter aortic valve replacement. Mean age was 68,96±11,98 years, and most patients were male. Remodeling evaluation revealed that patients who decreased left ventricular index mass (53% vs. 38.9%; P=0,019) and those who reduced the mass/volume ratio (30.4% vs. 68.9%; P<0,001) presented with positive left ventricular remodeling. No endpoint difference was found in those with positive remodeling. Conclusion: Regarding the left ventricular remodeling in patients with severe and symptomatic aortic valve stenosis who underwent percutaneous transcatheter or surgical valve replacement, there is a positive increment in remodeling, however it remains in concentric hypertrophic shape. Implication of these findings remains uncertain and to be studied in large dedicated trials with clinical endpoints.
RESUMO
Abstract Background There is no consensus among tools for assessing frailty. Objective To evaluate the prevalence of frailty according to different tools in patients referred for elective valve cardiac surgery. Methods This is a cross-sectional study. All patients were ≥ 18 years of age, clinically stable. The following patients were excluded: those unable to perform the tests because of physical, cognitive, or neurological limitations; those requiring non elective/emergency procedures or hemodynamic instability. During the preoperative cardiology visit, frailty was assessed by the Short Physical Performance Battery (SPPB), the Frailty Deficit Index (FDI), handgrip strength, and gait speed 3m. For the entire analysis, the statistical significance was set at 5%. Results Our cohort consisted of 258 subjects. From the total cohort, 201 were ≤ 70 years of age (77.9%), the predominant etiology according to rheumatic disease (50.7% vs 8.8%; p=0.000) with double mitral lesion (24.9% vs 0%; p=0.000). Frailty was present in 32.9% according SPPB, 29.1% with reduced muscular strength. and 8.9% with FDI. Handgrip strength was weaker in elderly patients (26.7 vs 23.6; p=0.051) and gait speed was lower in the younger group, in which 36% were considered frail (36% vs 14%; p=0.002). Variables associated with frailty were age ≥ 70 years, female gender, aortic stenosis, and regurgitation. Conclusion Frailty in adult patients who will have elective heart valve surgery is present even in the younger groups, although the older group with comorbidities are more frail. Frailty was more clearly shown by the SPPB than by the FDI and handgrip tests.

RESUMEN Introducción: La enfermedad valvular constituye una patología prevalente y con considerable morbimortalidad. A pesar de que representa una problemática de salud pública reconocida, en nuestro país, no disponemos de datos sobre su epidemiología. El objetivo del trabajo fue identificar la prevalencia y etiología de las enfermedades valvulares en los pacientes que concurren a los laboratorios de ecocardiografía en forma ambulatoria. Materiales y métodos: Se realizó un registro retrospectivo, observacional y multicéntrico, en el que participaron 18 centros de Argentina. A todos los pacientes se les realizó un ecocardiograma transtorácico completo, en el cual el análisis de la función valvular fue realizado por operadores calificados. Se recolectaron variables demográficas, causas y grado de compromiso de la función valvular. Resultados: Se incluyeron 3020 pacientes (51,2% de sexo masculino), con una edad media de 58,2 ± 16,8 años. En el 61,7%, se observó algún grado de alteración valvular; en el 9,5%, al menos, una valvulopatía de grado significativo (moderado o mayor) y en el 1,7% valvulopatías significativas combinadas. El 4% de la población presentó estenosis aórtica significativa, que fue la valvulopatía significativa más frecuente, seguida por la insuficiencia mitral (2,9%) y la insuficiencia tricuspídea (2,3%). La etiología degenerativa fue la causa más frecuente de disfunción valvular aórtica y mitral, y la causa funcional la principal de insuficiencia tricuspídea significativa. Las valvulopatías significativas aumentaron significativamente con la edad, y afectaron al 23,5% de los mayores de 75 años. La estenosis mitral y la insuficiencia tricuspídea fueron más frecuentes en pacientes de sexo femenino, sin encontrarse diferencias de género en las valvulopatías aórticas y la insuficiencia mitral. Conclusiones: Las enfermedades valvulares fueron un hallazgo frecuente en nuestra población. Su prevalencia aumentó con la edad; la etiología degenerativa fue la principal causa de compromiso valvular aórtico y mitral, y la funcional de la insuficiencia tricuspídea. La estenosis mitral y la insuficiencia tricuspídea tuvieron diferencias de acuerdo al sexo. Nuestro trabajo aporta información importante y novedosa sobre la epidemiología de las valvulopatías en Argentina.
ABSTRACT Background: Valvular heart disease is a prevalent pathology with considerable morbidity and mortality. Despite it represents a well-known public health problem, there is no epidemiological data available in our country. The aim of this study was to assess the prevalence and etiology of valvular heart disease in ambulatory patients referred for transthoracic echocardiography. Methods: A retrospective, observational and multicenter registry was carried out with the participation of 18 Argentine centers. All patients underwent a complete transthoracic echocardiogram, in which the analysis of valvular function was performed by qualified operators. Demographic variables, causes and degree of valvular function involvement were collected. Results: A total of 3020 patients (51.2% male) with mean age of 58.2 ± 16.8 years were included in the study. In 61.7% of patients some degree of valvular abnormality was observed; in 9.5% of cases at least one significant valve disease (moderate or greater) and in 1.7% a significant combined valve disease was observed. Four percent of the population had significant aortic stenosis, which was the most common major valve disease, followed by mitral regurgitation (2.9%) and tricuspid regurgitation (2.3%). The most frequent cause of aortic and mitral valve defect was degenerative and functional for significant tricuspid regurgitation. Significant heart valve disease increased notably with age, affecting 23.5% of patients older than 75 years. Mitral stenosis and tricuspid regurgitation were more frequent in female patients, with no gender differences in aortic valve disease and mitral regurgitation. Conclusions: Valvular heart diseases were a frequent finding in our population and their prevalence increased with age. Degenerative etiologies were the main cause of aortic and mitral valve involvement, while a functional etiology was responsible for most cases of tricuspid regurgitation. Gender-specific patterns were observed for mitral stenosis and tricuspid regurgitation. Our findings provide relevant unique data on the epidemiology of heart valve disease in Argentina.
RESUMO
Abstract A rare case of congenital mitral insufficiency characterized by a fenestration in the anterior leaflet of mitral valve is reported. At operation, the mitral valve was successfully repaired by closure of unusual valvular tissue orifice with bovine pericardium and suture of the free edge between A1 and A2 without a ring annuloplasty.
