Atrial fibrillation gut syndrome: severe gastroparesis with pyloric spasm following radiofrequency catheter ablation of drug resistant symptomatic atrial fibrillation: a case report.

BACKGROUND: Atrial fibrillation is the most common cardiac arrhythmia, and cardiac ablation is one of the treatment modalities for persistent symptomatic atrial fibrillation. Gastroparesis is a rare complication of radiofrequency catheter ablation for atrial fibrillation, which may be associated with high morbidity. CASE PRESENTATION: We present a 44-year-old Caucasian male with persistent atrial fibrillation who presented with nausea, vomiting, bloating, and constipation after radiofrequency catheter ablation. He was found to have gastroparesis due to pyloric spasm that was treated with botulinum toxin injection. CONCLUSION: This case signifies the importance of identifying gastric complications after radiofrequency catheter ablation atrial fibrillation, and the need for prompt diagnosis and treatment of gastroparesis with botulinum toxin injection.

A Case Series of Uncommon Sodium Disorders in Common Clinical Scenarios.

Dysnatremias or sodium disorders (either hyponatremia or hypernatremia) are the most common electrolyte problems in clinical medicine. They pose diagnostic and therapeutic challenges and have high mortality. Even mild changes in sodium levels from normal are associated with worse outcomes and considerable morbidity and mortality. We present a series of four patients with either hypo- or hypernatremia in different clinical scenarios requiring immediate treatment with close monitoring to avoid overcorrection. This case series shows that uncommon or unusual sodium disorders can happen in an otherwise usual situation.
