“…The success of balloon mitral valvotomy is characterised by an increased valvular area > 25% of the initial area and a mitral valvular area ≥ 1.5 cm 2 in the absence of mitral regurgitation > 2+, according to angiographic criteria. 9,10 The patient had an echocardiographic score of 10, subvalvular stenosis (3), thickening (2), mobility (3), and calcification (2). On radioscopy, she had a calcification of 2++.…”

A 45-year-old female Jehovah's Witness patient was diagnosed with Lutembacher syndrome, New York Heart Association (NYHA) class IV congestive heart failure (CHF), and severe malnutrition. An echocardiogram showed a 38 mm diameter ostium secundum atrial septal defect with a mitral valve area of 0.5 cm² and a Wilkins score of 10. The patient had severe pulmonary hypertension at an estimated systolic pressure of 96 mmHg. In addition, the right ventricle presented with significant dilation and severe dysfunction, and severe tricuspid valve regurgitation was also observed. Despite optimal clinical treatment, improvement was not observed in the CHF or in the patient's overall condition, which led to a change in the initial surgical treatment plan. A two-stage therapy was implemented, starting with a balloon mitral valvotomy as a bridge to surgery. The postoperative mitral valve area increased to 1.34 cm². The patient showed significant clinical improvement, and a mitral valve replacement surgery was performed 120 days later with a mechanical valve and atrioseptoplasty using a bovine pericardial patch, as well as tricuspid valve cerclage. The patient was discharged 11 days after the surgery, and is currently in the sixth postoperative month. She continues to show clinical stability and improvements in her quality of life.

“…8 Destaque especial quanto ao risco de reestenose foi dado, em recente análise de Cardoso et al 9 , à área valvar mitral pré-procedimento e à presença de calcificação mitral acentuada. O sucesso parcial do procedimento, ou resultado subótimo (obtenção de área valvar < 1,5 cm² na ausência de insuficiência mitral grave), também é um preditor de reestenose mitral precoce.…”

RESUMOPaciente do sexo feminino, 37 anos, portadora de estenose mitral de etiologia reumática, submetida, com sucesso, a valvotomia mitral percutânea em 1996, 2000 e 2005. Após 41 meses do terceiro procedimento, além de episódios de fibrilação atrial paroxística, voltou a apresentar dispneia aos moderados esforços. O estudo ecocardiográfico demonstrou gradiente transvalvar médio de 8 mmHg, pressão sistólica da artéria pulmonar de 55 mmHg, área valvar mitral de 1 cm² e escore de Wilkins de 10 pontos. Em decorrência da evidência de reestenose clínica e ecocardiográfica, indicou-se novo procedimento percutâneo, realizado sem intercorrências, porém obtendo-se resultado subótimo. DESCRITORES:Estenose da valva mitral. Dilatação com balão. Resultado de tratamento. ABSTRACT Percutaneous Mitral Valvotomy: Fourth DilatationThirty-seven-year-old female, previously diagnosed with mitral valve stenosis due to rheumatic fever, who had successfully undergone percutaneous mitral valvotomy in 1996, 2000 and 2005. Forty-one months after the third procedure, in addition to episodes of paroxystic atrial fibrillation, the patient had dyspnea after ordinary exertion. Echocardiographic evaluation revealed a mean transvalvular gradient of 8 mmHg, pulmonary artery systolic pressure of 55 mmHg, a mitral valve area of 1 cm², and a Wilkins score of 10 points. With the evidence of clinical and echocardiographic mitral restenosis, a new percutaneous procedure was performed, with no periprocedural complications, however, achieving suboptimal outcome. Uma VMP prévia (assim como uma comissurotomia cirúrgica prévia) não constitui por si só contraindicação para nova VMP, sendo a avaliação anatômica, obtida pelo escore ecocardiográfico de Wilkins 3 , e a condição clínica do paciente os principais parâmetros para a indicação do procedimento. KEY-WORDS:Estudos referentes aos resultados de segundas e terceiras dilatações são escassos na literatura 4 , e não encontramos relatos de pacientes que tenham sido submetidos a mais de três procedimentos.Relatamos o caso de uma paciente submetida eletivamente a VMP pela técnica de Inoue pela quarta vez. RELATO DO CASOA paciente recebeu o diagnóstico de estenose da valva mitral em 1996, aos 22 anos de idade, e foi encaminhada para acompanhamento no ambulatório especializado em valvopatias do Instituto Dante Pazzanese de Cardiologia, em São Paulo (SP, Brasil). Apresentava dispneia aos esforços (classe funcional II-III), e o exame físico demonstrava sopro diastólico em ruflar 3+/4+ em ápex e frêmito diastólico em foco mitral. Eletrocardiograma mostrava ritmo sinusal, com sobrecarga atrial esquerda. Ecocardiograma demonstrava área valvar mitral de 0,73 cm² (PHT), fração de ejeção do ventrículo esquerdo de 77% (Simpson), átrio esquerdo de 53 mm, valva mitral com insuficiência discreta e gradiente diastólico máximo de 29 e médio de 17, escore de Wilkins de 9 pontos, e pressão sistólica de artéria pulmonar de 75 mmHg.Confirmado o diagnóstico de estenose mitral grave, indicou-se a primeira VMP da paciente. O procedim...

The publication Cardiovascular Statistics – Brazil aims to provide an annual compilation of data and research on the epidemiology of CVDs in Brazil. The report integrates official statistics from the Brazilian Ministry of Health and other governmental entities alongside data from the GBD project, coordinated by the IHME at the University of Washington. Additionally, it incorporates data derived from various sources and scientific studies, including cohorts and registries, that relate to CVDs and their associated risk factors. This publication is intended for a wide range of individuals, including researchers, clinicians, patients, healthcare policymakers, media professionals, the general public, and other interested parties seeking extensive national data about heart disease and stroke. Volunteer researchers from various Brazilian universities and research institutions carry out the project. The group is led by a five-member steering committee (ALPR, CAP, DCM, GMMO, and LCCB). The Brazilian Society of Cardiology fully supports this initiative, and the project receives collaborative support from the GBD Brazil Network and an International Committee (GAR, PP, and TAG) from both the IHME/University of Washington (GAR) and the World Heart Federation (PP and TAG).
