Cardiac Rupture After Catheter Ablation Procedure

Cardiac rupture following catheter ablation procedure Short Title: Cardiac rupture

Cardiac injury after percutaneous catheter ablation for atrial fibrillation.

AIMS Small elevations in troponin T levels have been shown with limited radiofrequency (RF) ablation procedures for supraventricular tachycardia, usually to levels below the threshold for ischaemia or infarction. Left atrial catheter ablation for atrial fibrillation (AF) requires far more RF energy, therefore could be expected to have greater elevation in troponin T. We determined troponin T le...

Acute massive pulmonary embolism after radiofrequency catheter ablation: a rare complication after a common procedure.

A 41-year-old man received an electrophysiological study (EPS) and radiofrequency catheter ablation (RFCA) for atrioventricular reentrant tachycardia (AVRT) in our hospital. Massive pulmonary embolism (PE) with hypotension developed 9 hours after these procedures. After emergent pulmonary angiography and catheter-directed intrathrombus urokinase infusion and clot breaking, the patient recovered...

Nonthermal cardiac catheter ablation using photodynamic therapy.

BACKGROUND Radiofrequency ablation has limitations, largely related to creation of lesions by heating. Here, we report the first nonthermal ablation by applying photodynamic therapy (PDT) to cardiac tissues using a custom-made deflectable laser catheter. The present study investigated the feasibility of PDT for cavotricuspid isthmus ablation in a canine model. METHODS AND RESULTS We evaluated...

Impending rupture of the left atrium after impaction of left atrial ablation catheter.

A 60-year-old male presented with chronic atrial fibrillation. A trans-femoral catheter ablation was planned. The catheter was impacted in the left atrial wall (Fig. 1). Consequently, the procedure was interrupted before achieving resynchronisation. Catheter withdrawal was only possible after median sternotomy and closed manipulation of the catheter to release it.
