Abstract

A 42-year-old male with ischemic cardiomyopathy presented with acute bilateral femoral artery embolization. After management with embolectomy and fasciotomy in both femoral arteries, transthoracic echocardiography revealed two pedunculated highly mobile left ventricle (LV) thrombi. Given the procedural risk, anticoagulation therapy was recommended over surgery. However, the bleeding risk impeded the continuation of anticoagulation, which increased the thrombus size. Multiorgan failure and disseminated intravascular coagulopathy followed and the patient died. We also systematically reviewed the PubMed and Scopus databases for pedunculated LV thrombi cases and retrieved 74 and 63 reports respectively. Of these, 37 relevant reports (45 cases) plus 11 reports from the manual search were included for data extraction, a total of 56 cases besides our case. Based on the etiologies and risks, LV thrombi are predictable and preventable, especially after ischemic events. A clear diagnostic algorithm and vigilant follow-up are needed as well as multidisciplinary management once a diagnosis is confirmed.

Resumo

Relatamos o caso de um homem de 42 anos com cardiomiopatia isquêmica que apresentou embolização aguda bilateral das artérias femorais. Embolectomia das artérias femorais e fasciotomia foram realizadas bilateralmente e, posteriormente, o ecocardiograma transtorácico revelou a presença de dois trombos pedunculados altamente móveis no ventrículo esquerdo (VE). Diante do risco associado à abordagem cirúrgica, recomendou-se terapia anticoagulante. No entanto, o risco de sangramento impediu a continuação da anticoagulação, o que levou ao aumento dos trombos. Posteriormente, o paciente evoluiu com falência de múltiplos órgãos e coagulação intravascular disseminada, vindo a óbito. Além do relato de caso, realizamos buscas sistemáticas nas bases de dados PubMed e Scopus por casos de trombos pedunculados no VE. Foram recuperados 74 e 63 relatos, respectivamente, dos quais 37 relatos relevantes (45 casos) e 11 da busca manual foram selecionados para extração de dados, totalizando 56 casos além do nosso. Com base nas etiologias e nos riscos, os trombos no VE são previsíveis e evitáveis, especialmente após eventos isquêmicos. Isso requer um algoritmo diagnóstico claro e acompanhamento vigilante, bem como manejo multidisciplinar após confirmação do diagnóstico.
