A 36-year-old woman with a medical history of opioid use disorder and frequent urinary tract infections presented to the ED from her opioid use disorder clinic, where she was found to have an oxygen saturation by pulse oximetry (Spo2) of 82% on room air. Starting 3 days before presentation, the patient's family noted worsening pale complexion and blue lips at rest. These findings of cyanosis had occurred a few times before and always resolved within a couple days without any medical intervention. ⋯ She had no dietary restrictions, had been eating her normal diet, and lived in a mobile home with her family, two dogs, and a gerbil. The patient reported using less than 10 tobacco cigarettes per day, one marijuana cigarette nightly, and no alcohol or other drugs. She worked in a warehouse stacking prepackaged bread.

A 35-year-old woman at 36 weeks and 4 days gestation with known complete anterior placenta previa and no other medical history presented for routine obstetric follow-up. She reported increasing fatigue in the prior week but otherwise endorsed no new concerns. She denied recent vaginal bleeding or discharge, abdominal pain, contractions, or extremity swelling. ⋯ She received bupivacaine spinal anesthesia for the procedure. The surgical procedure progressed with a low transverse uterine incision and subsequent delivery of the baby with no complications noted. Immediately after delivery of the baby and during gentle traction of the placenta, the patient experienced rapid cardiovascular collapse in the form of hypotension and bradycardia.

A 41-year-old man who currently smokes with previous sporadic use of cocaine and cannabinoids was admitted at the hospital suffering from hemoptysis which had developed 4 days before. The patient was on anticoagulant therapy with rivaroxaban due to paroxysmal atrial fibrillation diagnosed in 2018, for which he had undergone pulmonary vein electrical isolation by radiofrequency and ablation of cavotricuspid isthmus in January 2019. ⋯ In February 2021, a new attempt at ablation was performed by electrical isolation of the left atrial posterior wall. The latest cardiologic checkup documented an echocardiographic framework of mild left atrial dilatation and normal-sized right ventricle with longitudinal shortening index at the lower limits, and a recurrence of asymptomatic atrial fibrillation at Holter ECG (March 2022).
