Abstract

ABSTRACTBACKGROUND AND OBJECTIVES: Takotsubo cardiomyopathy, also known as broken heart syndrome is a stress-induced cardiomyopathy, which can be interpreted as an acute coronary syndrome as it progresses with suggestive electrocardiographic changes. The purpose of this article is to show the importance of proper monitoring during surgery, as well as the presence of an interdisciplinary team to diagnose the syndrome.CASE REPORT: Male patient, 66 years old, with diagnosis of gastric carcinoma, scheduled for diagnostic laparoscopy and possible gastrectomy. In the intraoperative period during laparoscopy, the patient always remained hemodynamically stable, but after conversion to open surgery he presented with ST segment elevation in DII. ECG during surgery was performed and confirmed ST-segment elevation in the inferior wall. The cardiology team was contacted and indicated the emergency catheterization. As the surgery had not yet begun irreversible steps, we opted for the laparotomy closure, and the patient was immediately taken to the hemodynamic room where catheterization was performed showing no coronary injury. The patient was taken to the hospital room where an echocardiogram was performed and showed slight to moderate systolic dysfunction, with akinesia of the mid-apical segments, suggestive of apical ballooning of the left ventricle. Faced with such echocardiographic finding and in the absence of coronary injury, the patient was diagnosed with intraoperative Takotsubo syndrome.CONCLUSION: Because the patient was properly monitored, the early detection of ST-segment elevation was possible. The presence of an interdisciplinary team favored the syndrome early diagnosis, so the patient was again submitted to safely intervention, with the necessary security measures taken for an uneventful new surgical intervention.

Resumo

RESUMOJUSTIFICATIVA E OBJETIVOS: A cardiomiopatia de takotsubo, também conhecida como síndrome do coração partido, é uma cardiomiopatia induzida por estresse que pode ser interpretada como uma síndrome coronária aguda, pois cursa com alterações eletrocardiográficas sugestivas. O objetivo do presente artigo é mostrar a importância de uma monitoração adequada no intraoperatório, assim como a presença de uma equipe interdisciplinar para o diagnóstico da síndrome.RELATO DE CASO: Doente masculino, 66 anos, com o diagnóstico de carcinoma gástrico, proposto para laparoscopia diagnóstica e possível gastrectomia. No intraoperatório durante a laparoscopia manteve sempre estabilidade hemodinâmica, porém após a conversão para cirurgia aberta apresentou elevação do segmento ST em DII e foi feito um ECG no intraoperatório que confirmou supradesnivelamento do segmento ST em parede inferior. Foi contactada a equipe de cardiologia, que indicou cateterismo de urgência. Como a cirurgia ainda não havia iniciado passos irreversíveis, optou-se pelo encerramento da laparotomia e o doente foi levado imediatamente para a sala de hemodinâmica. Foi feito cateterismo que não evidenciou lesão nas coronárias. O doente foi levado para o internamento, onde foi feito um ecocardiograma que mostrava disfunção sistólica ligeira a moderada, com acinésia dos segmentos médio-apicais, imagem sugestiva de balonamento apical do ventrículo esquerdo. Diante de tal achado ecocardiográfico e na ausência de lesões coronárias, foi diagnosticada síndrome de takotsubo intraoperatória.CONCLUSÃO: Devido ao fato de o doente estar monitorado de uma forma adequada foi possível a detecção precoce do supradesnivelamento do segmento ST. A presença de uma equipe interdisciplinar favoreceu o diagnóstico precoce da síndrome. Dessa forma o doente foi novamente intervencionado de forma segura e foram tomadas as devidas medidas de segurança, para que a nova intervenção cirúrgica transcorresse sem intercorrências.
