Multidisciplinary Approach for Lung Transplantation due to COVID-19

Coronavirus disease 2019 (COVID-19), a novel etiology of end-stage lung disease, has resulted in major disruptions to the process of health care delivery worldwide. These disruptions have led to team-based innovations globally, resulting in a broad range of new processes in cardiopulmonary perioperative management. A key intersection of multidisciplinary teamwork and COVID-19 is found in lung transplantation, in which diverse teams collaborate throughout the perioperative period to achieve optimal outcomes. In this article, we describe the multidisciplinary approach taken by Mayo clinic in Florida to manage patients with COVID-19 presenting for lung transplantation.

Pheochromocytoma Crisis Presenting With ARDS Successfully Treated With ECMO-Assisted Adrenalectomy

Objective

Pheochromocytoma (PCC) crisis caused by acute catecholamine release from an adrenal PCC or extra-adrenal paraganglioma can be difficult to diagnose and may require an unconventional management strategy to achieve good outcomes. We describe a case of PCC crisis presenting with acute respiratory distress syndrome (ARDS) that resolved with stabilization on veno-venous (VV) extracorporeal membrane oxygenation (ECMO) during adrenalectomy.

Case Description

A 30-year-old man with a history of severe alcohol use disorder and a prior hospital admission for alcohol withdrawal syndrome presented with sudden-onset hemoptysis, altered mental status, and severe dyspnea that rapidly deteriorated to ARDS requiring ECMO support. He demonstrated hemodynamic collapse after cannulation for VV-ECMO and stabilized after conversion to veno-arterial-ECMO, but ARDS persisted and he developed acute renal failure. Computed tomography without contrast done as part of work-up for a presumed infection revealed a 6.9 × 6.4 cm right adrenal mass suspicious for pheochromocytoma. Plasma and random urine metanephrine levels were markedly elevated. ARDS persisted despite α- and β-adrenoreceptor blockade, and he underwent laparoscopic right adrenalectomy with VV-ECMO support. Pathology confirmed PCC with intermediate risk for malignancy. Postoperatively, he was weaned off respiratory and renal support within 10 days, showed rapid clinical improvement, and was discharged 1 month later.

Conclusion

This case highlights diagnostic and management challenges associated with patients with PCC crisis presenting with ARDS. A multidisciplinary team approach is critical to identifying appropriate treatment strategies.

Severe Tricuspid Valve Endocarditis: A Tale of 2 Circuits

A 25-year-old woman with severe tricuspid valve endocarditis and septic pulmonary emboli required VA-ECMO for recurrent hypoxemia-induced cardiac arrest. We present the clinical challenges requiring ECMO circuit reconfiguration and a percutaneous approach for vegetation debulking. (Level of Difficulty: Intermediate.).

COVID-19 associated Multisystem Inflammatory Syndrome in Children (MIS-C) guidelines; revisiting the Western New York approach as the pandemic evolves

Multisystem inflammatory syndrome of children (MIS-C) continues to be a highly concerning diagnosis in those recently infected with SARS-CoV-2. The diagnosis of MIS-C cases will likely become even more challenging as vaccine uptake and natural immunity in previously infected persons leads to lower circulating rates of SARS-CoV-2 infection and will make cases sporadic. Febrile children presenting with cardiac dysfunction, symptoms overlapping Kawasaki disease or significant gastrointestinal complaints warrant a thorough screen in emergency departments, urgent care centers, and outpatient pediatric or family medicine practices. An increased index of suspicion and discussion regarding higher level of care (transferring to pediatric tertiary care centers or to intensive care) continues to be recommended. Herein we outline a broad approach with a multidisciplinary team for those meeting the case definition and believe such an approach is crucial for successful outcomes.
