RESUMEN
We present a rare cause of pulmonary arterial hypertension in a 29-year-old woman with rapidly progressive and fatal hypoxia. Subsequent workup revealed classic radiological findings and pathologic confirmation of pulmonary veno-occlusive disease.
RESUMEN
Direct acting oral anticoagulants (DOACs) have become the mainstay of treatment for patients requiring anticoagulation for atrial arrhythmias and venous thromboembolism (VTE) but safety and efficacy has not been established in lung transplantation. This is a retrospective review of 28 adult lung transplant patients who were prescribed apixaban for stroke prevention in atrial arrhythmias or treatment of VTE between October 15, 2015 and December 31, 2018. The primary outcome was a composite of efficacy and safety measured by recurrence or breakthrough of stroke or thromboembolism and bleeding events. Seven patients were treated for atrial arrhythmias and 21 treated for VTE. Fifteen patients received CYP3A4 or P-gp inhibitors at initiation of anticoagulation, and 4 of these patients received strong CYP3A4 inhibitors. During the follow-up period, one breakthrough DVT and one clinically relevant non-major bleed were observed. These data suggest that apixaban may be safe to use for lung transplant patients, and larger studies are warranted to assess long-term outcomes as well as safety and efficacy of alternative DOACs.

We present a case of a 57-year-old man who underwent bilateral lung transplantation for idiopathic pulmonary fibrosis. His immediately post-operative course was complicated by fever and cardiac arrest. Despite supportive care and broad-spectrum antibiotics, he experienced continued clinical decline. Autopsy results indicated angioinvasive mucormycosis and coronary arteritis resulting in acute myocardial infarction as the cause of death.
RESUMEN
We report a patient with hypoxia secondary to a right-to-left shunt through a patent foramen ovale, following aortic root, valve, and arch replacement due to an aortic dissection in the setting of the Marfan syndrome. Following the operation, he failed extubation twice due to hypoxia. An extensive workup revealed a right-to-left shunt previously not seen. The patent foramen ovale was closed using a percutaneous closure device. Following closure, our patient was extubated without difficulty and has done well postoperatively.
