Esophageal rupture complicated by a gastrocardiac fistula: review of the literature and report of a successfully treated case

A case of a death caused by an atrial-oesophageal-thoracic fistula after radiofrequency ablation of atrial fibrillation

The report is about a 49-year-old man with rheumatic heart disease and atrial fibrillation. He underwent mitral valve replacement, tricuspid valvuloplasty, and atrial fibrillation radiofrequency ablation in the hospital. He vomited blood on the 2nd postoperative day, and the bleeding gradually worsened thereafter. He had to have repeated drainage of large amounts of blood from his right thoracic cavity and digestive tract. He died suddenly after undergoing an oesophageal endoscopy on the 24th postoperative day. The autopsy revealed an atrial-oesophageal-thoracic fistula. By excluding the possibility of the fistula being caused by complications from nasoenteric feeding, tracheal intubation, and a foreign body ingestion, we determined that the atrial-oesophageal-thoracic fistula was a complication after radiofrequency ablation according to the finding of coagulation necrosis of the myocardial cells at the left atrium fistula. In addition, we also performed an elemental analysis on the radiofrequency ablation area and other cardiac tissues by scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) and found five metal elements, Cr, Cu, Zn, Mn, and Ti, which specifically existed in the radiofrequency ablation area. This finding has the potential to serve as new evidence for radiofrequency ablation and is a worthy direction of research.

Gastro-right ventricular fistula: a deadly complication of a gastric pull-through

A 70-year-old patient presented with melena, dyspnea, and generalized weakness. An endoscopy revealed a deep ulcer with a pulsatile clot in the intrathoracic gastric tube that had been previously constructed for esophageal replacement. Shortly thereafter, the patient died of exsanguination secondary to a fistula between the stomach and the right ventricle. This complication presents a unique but deadly cause of gastrointestinal bleeding that mandates swift diagnosis and immediate surgical correction.

Gastroaortic fistula as an early complication of esophagectomy

Gastroaortic fistula following esophagogastrectomy is an uncommon and invariably fatal complication without urgent surgical intervention. We report 1 such case and review the world literature identifying 22 previous cases. It characteristically presents 2 to 3 weeks after esophagogastrectomy with an initial herald bleed, followed by a latent period with a mean duration of 10 hours (range: 30 minutes to 3 days) and final exsanguination. Only 1 patient in this series survived. Awareness is necessary to allow prompt diagnosis and treatment of this almost invariably lethal but curable condition.
