Physiologic changes of pregnancy are poorly tolerated in patients with pulmonary arterial hypertension (PAH), and peripartum maternal mortality is high. We present a case of a 31-year-old G3P0020 patient at 35 weeks' gestation with severe World Health Organization group I PAH who underwent cesarean delivery followed by percutaneous right ventricular assist device placement. Risks and benefits of the mode of delivery, neuraxial versus general anesthesia, and mechanical circulatory support are reviewed.

Case Reports
Tranexamic Acid in Cardiac Surgery: A Case Report of an Infrequent Adverse Reaction to a Common Medication.
Life-threatening anaphylaxis to tranexamic acid (TXA) is rare but critical in cardiac surgery. A 76-year-old patient undergoing elective ascending aorta replacement developed severe anaphylactic shock shortly after anesthesia induction. ⋯ Guided by rotational thromboelastometry, hemostatic therapy led to a successful outcome with minimal postoperative bleeding. This report emphasizes the importance of drug risk awareness and strategies to mitigate excessive bleeding in cardiac surgery.

Recently, denervation therapies have drawn attention as a promising treatment, and cooled radiofrequency has been proposed as the best option to capture most of the genicular nerves. We present a rare case of synovial knee fistula after radiofrequency and its management. ⋯ One week later, the fistula was closed, and 14 months later, the procedure was repeated without complications. Genicular radiofrequency ablation is an emerging technique, and providers should be aware of the reported complications to counsel patients and manage potential risks appropriately.

Case Reports
Fentanyl-Induced Serotonin Syndrome 5 Days After Cessation of Serotonergic Agents: A Case Report.
A 21-year-old patient with intellectual disability was admitted for gastroenteritis due to serotonergic medication overdose, and subsequently developed serotonin syndrome. Her symptoms initially improved after the cessation of serotonergic medications, but worsened 5 days later after fentanyl administration during general anesthesia. On emergence, she had convulsions and was nonresponsive. ⋯ We suspect she had an exacerbation of her serotonin syndrome. She recovered successfully after supportive care. This case demonstrates that common medications used during anesthesia such as fentanyl can provoke serotonin syndrome, even several days after serotonergic drug discontinuation.
