ABSTRACT

Apresentamos o caso debutante na América Latina de reparos transcateteres edge- to-edge nas valvas mitral e tricúspide em um único procedimento em paciente de alto risco para cirurgia. A paciente evoluía com insuficiência cardíaca e limitações em suas atividades diárias quando foi submetida ao procedimento, no qual foram realizados os reparos transcateteres das valvas mitral e tricúspide. Aos 6 meses de evolução, estava assintomática e realizando suas atividades diárias. Debatemos as recomendações mais atualizadas sobre a terapia transcateter para coexistência dessas doenças valvares, assim como expomos as lacunas no conhecimento.


We present the first case in Latin America of transcatheter edge-to-edge mitral and tricuspid valve repair in a single procedure, in a patient at high risk for surgery. The patient progressed to heart failure and limitation in her daily living activities when she was submitted to transcatheter mitral and tricuspid valve repair. Six months later, she was asymptomatic and performing her daily living activities. We discuss the most updated recommendations for transcatheter repair when both valvar conditions coexist, and show the knowledge gaps.

ABSTRACT

Resumo Fundamento A intervenção percutânea em pacientes com disfunção de prótese biológica mitral apresenta-se como uma alternativa ao tratamento cirúrgico convencional. Objetivo Relatar a primeira experiência brasileira de implante transcateter de bioprótese valve-in-valve mitral via transeptal (TMVIV-via transeptal). Métodos Foram incluídos pacientes portadores de disfunção de bioprótese cirúrgica submetidos ao TMVIV-transeptal em 12 hospitais brasileiros. Foram considerados estatisticamente significativos valores de p<0,05. Resultados Entre junho/2016 e fevereiro/2019, 17 pacientes foram submetidos ao TMVIV-via transeptal. A mediana de idade foi 77 anos (IIQ,70-82), a mediana do escore STS-PROM foi 8,7% (IIQ,7,2-17,8). Todos os pacientes tinham sintomas limitantes de insuficiência cardíaca (CF≥III), tendo 5 (29,4%) sido submetidos a mais de uma toracotomia prévia. Obteve-se sucesso do TMVIV-via transeptal em todos os pacientes. A avaliação ecocardiográfica demonstrou redução significativa do gradiente médio (pré-intervenção, 12±3,8 mmHg; pós-intervenção, 5,3±2,6 mmHg; p<0,001), assim como aumento da área valvar mitral (pré-intervenção, 1,06±0,59 cm2; pós-intervenção, 2,18±0,36 cm2; p<0,001) sustentados em 30 dias. Houve redução significativa e imediata da pressão sistólica de artéria pulmonar, com redução adicional em 30 dias (pré-intervenção, 68,9±16,4 mmHg; pós-intervenção, 57,7±16,5 mmHg; 30 dias, 50,9±18,7 mmHg; p<0,001). Durante o seguimento, com mediana de 162 dias (IIQ, 102-411), observou-se marcada melhora clínica (CF≤II) em 87,5%. Um paciente (5,9%) apresentou obstrução de via de saída de ventrículo esquerdo (VSVE), evoluindo para óbito logo após o procedimento, e outro morreu aos 161 dias de seguimento.Conclusão: A primeira experiência brasileira de TMVIV-transeptal demonstra a segurança e a efetividade dessa nova técnica. A obstrução da VSVE é uma complicação potencialmente fatal, reforçando a importância da seleção dos pacientes e do planejamento do procedimento.

Abstract Background Percutaneous intervention in patients with bioprosthetic mitral valve dysfunction is an alternative to conventional surgical treatment. Objectives To report the first Brazilian experience with transseptal transcatheter bioprosthetic mitral valve-in-valve implantation (transseptal-TMVIV). Methods Patients with surgical bioprosthetic dysfunction submitted to transseptal-TMVIV in 12 Brazilian hospitals were included. The significance level adopted was p<0.05. Results From June/2016 to February/2019, 17 patients underwent transseptal-TMVIV. Their median age was 77 years (IQR,70-82) and median Society of Thoracic Surgeons predicted risk of mortality (STS-PROM) score was 8.7% (IQR,7.2-17.8). All patients had limiting symptoms of heart failure (FC≥III) and 5 (29.4%) had undergone more than one previous thoracotomy. Transseptal-TMVIV was successful in all patients. Echocardiographic assessment showed a significant reduction in mean mitral valve gradient (pre-intervention, 12±3.8 mmHg; post-intervention, 5.3±2.6 mmHg; p<0.001), in addition to an increase in mitral valve area (pre-intervention, 1.06±0.59 cm2; post-intervention, 2.18±0.36 cm2; p<0.001) sustained for 30 days. There was a significant and immediate reduction in the pulmonary artery systolic pressure, with an additional reduction in 30 days (pre-intervention, 68.9±16.4 mmHg; post-intervention, 57.7±16.5 mmHg; 30 days, 50.9±18.7 mmHg; p<0.001). During follow-up (median, 162 days; IQR, 102-411), significant clinical improvement (FC≤II) was observed in 87.5% of the patients. One patient (5.9%) had left ventricular outflow tract (LVOT) obstruction and died right after the procedure, and another died at 161 days of follow-up. Conclusion The first Brazilian experience with transseptal-TMVIV shows the safety and effectivity of the new technique. The LVOT obstruction is a potentially fatal complication, reinforcing the importance of patients' selection and of procedural planning. (Arq Bras Cardiol. 2020; [online].ahead print, PP.0-0)

ABSTRACT

BACKGROUND: A 69-year-old male patient with severe asymptomatic carotid artery stenosis was treated percutaneously with implant of two self-expandable stents in the right carotid overlapped to each other by 5 mm. The 15-month follow-up colour-Doppler ultrasound (CDU) revealed a severe stenosis in the target vessel and an image suggesting migration of the distal stent. INVESTIGATIONS: Physical examination, laboratory test, CDU, carotid angiography, quantitative carotid angiography (QCA), brain computed tomography (CT). DIAGNOSIS: Migration of the distal stent associated with severe stenosis on the unsupported arterial segment. MANAGEMENT: Carotid artery angiography, QCA, antithrombotic therapy, carotid artery angioplasty and stenting (CAS).

ABSTRACT

We report on the case of a patient with a long term vascular catheter embolized into the right ventricle. This case had unique characteristics since both ends of the catheter were inaccessible for snare, which made it difficult to capture them using conventional techniques. We describe a new method to retrieve the foreign body through its mid-point portion, using a single catheter with two independent snare and hook systems.

ABSTRACT

Relatamos o caso de um paciente com cateter vascular de longa permanência embolizado para o ventrículo direito. Este caso ganha peculiaridade por estarem as duas extremidades do cateter indisponíveis para serem laçadas, dificultando a sua captura pelas técnicas convencionais. Descrevemos um novo método para resgatar o corpo estranho através de sua porção central, utilizando apenas um cateter com dois sistemas independentes de "laço" e de "gancho".
