Abstract:
The pathophysiology of jackhammer esophagus is complex and remains unclear. Radiofrequency catheter ablation is indicated for highly symptomatic and drug-refractory atrial fibrillation. This technique can induce esophageal and nerve lesions, due to thermal injury. In this report, we describe a case of hypercontractile esophagus diagnosed by HRM (high-resolution manometry). Esophageal symptoms and HRM normalized immediately after RFCA, and we discuss the pathophysiology of hypercontractile esophagus.
