Preoperative Coronary Intervention Before Orthotopic Liver Transplantation (from a Review of Literature).

There is significant morbidity and mortality associated with the presence of coronary artery disease (CAD) in the setting of orthotopic liver transplantation in patients with end-stage liver disease. The prevalence of CAD in this cohort is similar to, if not higher, than the general population. Several studies show improved survival rates for patients with obstructive CAD who undergo percutaneous coronary intervention (PCI) and support a low threshold for PCI in these patients. However, a few studies have failed to show improved mortality associated with PCI in this cohort. This review hopes to highlight the current recommendations regarding the assessment of CAD in patients with end-stage liver disease who are orthotopic liver transplantation candidates and describe the outcomes of PCIs.

Esophagopericardial Fistula and Pneumopericardium as a Complication of Pulmonary Vein Isolation in a 62-Year-Old Man with Atrial Fibrillation: A Case Report.

BACKGROUND Pulmonary vein isolation is a method of cardiac ablation therapy used to treat irregular heart rhythm, including atrial fibrillation (AF). This report presents a case of esophagopericardial fistula (EPF) and pneumopericardium as a complication of pulmonary vein isolation in a 62-year-old man with AF. CASE REPORT We report the rare case of a 62-year-old man with a medical history of persistent atrial fibrillation status after ablation 3 days prior to his initial Emergency Department visit for chest pain. Acute coronary syndrome was ruled out with normal electrocardiogram, echocardiography, and troponin tests. Fluid overload and sotalol adverse effects were presumed to be the cause of his symptoms. We discontinued sotalol with diuresis and he was discharged home when his chest pain subsided. Nine days later, he returned to the Emergency Department with worsening similar symptoms and was eventually diagnosed with EPF and pneumopericardium on a computed tomography scan of the chest with contrast. He was managed with esophagogastroduodenoscopy and stent placement along with subxiphoid pericardial window and pericardial drain placement. The patient was discharged in stable condition after removing the pericardial drain. At 10-day and 1-month follow-up, he had no recurrent symptoms. CONCLUSIONS This report shows that although EPF with pneumopericardium is a rare complication of pulmonary vein isolation, it should be rapidly diagnosed and treated as a life-threatening emergency.

Neuromyelitis Optica Spectrum Disorder: A Rare Cause of Spinal Cord and Optic Nerve Involvement.

Neuromyelitis optica spectrum disorder (NMOSD) is defined as a rare central nervous system, demyelinating, autoimmune disorder with autoantibodies against aquaporin-4. Commonly affecting females, NMOSD is known to also be a relapsing disease and can increase in severity during each episode. Diagnostic criteria include ruling out multiple sclerosis, spinal magnetic resonance imaging, and autoantibody detection. While management focuses on relapse treatment and prevention, high-dose steroids and plasma exchange have proven to be useful options. We present a case of a young female presenting with NMOSD relapse appropriately managed with plasma exchange.
