RESUMO
BACKGROUND: Floating right heart thrombi (RHT) represent an underdiagnosed, potentially hazardous, and to some extent rare phenomenon in patients presenting with acute pulmonary embolism (APE). Emergent treatment is usually required for such a condition. CASE PRESENTATION: A 19-year-old young lady presented with progressive shortness of breath, marked renal impairment, thrombocytopenia, and a highly oscillating huge right atrial mass. After she was admitted to the intensive care unit, she arrested in asystole and was resuscitated, and her electrocardiogram (ECG) showed evidence of acute anterior myocardial infarction. Urgent cardiac surgery to remove the right atrial mass was proposed by the heart team as the best option of management. Surgery was emergently performed with extra-corporeal membrane oxygenator (ECMO) as a support. Following surgery, mechanical support and vasopressors were successfully weaned and the patient achieved a good recovery. CONCLUSIONS: A pulmonary embolism response team (PERT) approach should always be considered where a multidisciplinary team involving a cardiologist, radiologist, cardio-thoracic surgeon, radiologist, and intensivist shall determine the management strategy for a challenging presentation of a massive pulmonary embolism or floating right heart thrombi causing the hemodynamically unstable clinical condition.
