Aeroembolism in left atrium during catheter ablation of atrial fibrillation in a patient with dextrocardia: a case report and review of the literature.

Background: Air embolus penetrating into heart chamber as a complication during percutaneous radiofrequency catheter ablation has been infrequently reported.

Case Presentation: A 55-year-old man with dextrocardia who suffered from abdominal pain was suspected to have multiple arterial thromboembolisms, which might have originated from left atrium thrombosis since he had atrial fibrillation. He received oral anticoagulant therapy and catheter ablation of the arrhythmia.

Trimetazidine in conditions other than coronary disease, old drug, new tricks?

Trimetazidine (TMZ) has traditionally been used as an anti-ischemic drug for coronary artery disease by selectively inhibiting the mitochondrial long-chain 3-ketoacyl-CoA thiolase. Recently, new applications for this therapy have been investigated. This article reviews alternative uses for TMZ in non-coronary artery diseases, such as non-ischemic cardiomyopathy, sepsis, myocardial dysfunction induced by anti-cancer drugs, diabetic cardiomyopathy and contrast-induced nephropathy.

Treatment strategy for treating atrial-esophageal fistula: esophageal stenting or surgical repair?: A case report and literature review.

Introduction: Atrial-esophageal fistula (AEF) is a rare severe disease, which may be associated with radiofrequency catheter ablation (RFCA) of atrial fibrillation (AF) or intraoperative radiofrequency ablation of atrial fibrillation (IRAAF).

Clinical Findings: We reported a case of a 67-year-old man with AEF following RFCA of AF, who treated with esophageal stenting and surgical repair.

Outcomes: He was attacked by out-of-control sepsis and infectious shock after surgery and died.

[Preliminary clinical experience on radiofrequency catheter ablation of right-sided accessory pathway guided by Ensite-NavX navigation].

Objective: To explore the feasibility and methodology of radiofrequency catheter ablation (RFCA) guided by 3D navigation system (Ensite-NavX) for right atrioventricular accessory pathway.

Method: Thirty-three cases of right accessory pathway atrioventricular reentrant tachycardia including 16 cases in right free wall, 3 in right middle septum, 14 in right posterior septum; 23 cases of dominant accessory pathway and 10 cases of concealed were treated by RFCA guided by NavX navigation. NavX navigation modeling method or spatial localization method was exploited to locate target positioning.
