Radiofrequency Ablation at Low Irrigation Flow Rates Using a Novel 12-Hole Gold Open-Irrigation Catheter

Single side hole irrigation--a simple method of catheter irrigation of the tendon sheath.

Treatment of septic flexor tenosynovitis at the hand requires significant hospital resources in terms of operative time and subsequent management of tendon irrigation. Delayed recovery or treatment failure may require re-irrigation and drainage. This may be due to failure to adequately irrigate the entire flexor sheath. We describe a method of closed tendon sheath irrigation which is simple to ...

Randomized comparison of cavotricuspid isthmus ablation for atrial flutter using an open irrigation-tip versus a large-tip radiofrequency ablation catheter.

BACKGROUND Large-tip (10 mm) catheters (LTCs) and open-irrigation-tip catheters (OITCs), both capable of creating large lesions, are more effective than conventional catheters for cavotricuspid isthmus (CTI) ablation. However, it is not clear whether complete CTI block can be achieved more efficiently using an LTC or an OITC. The purpose of this study was to compare the efficiency of radiofrequ...

Pulmonary vein antral isolation using an open irrigation ablation catheter for the treatment of atrial fibrillation: a randomized pilot study.

OBJECTIVES We sought to test how catheter ablation using an open irrigation catheter (OIC) compares with standard catheters for pulmonary vein antrum isolation. BACKGROUND Open irrigation catheters have the advantage of delivering greater power without increasing the temperature of the catheter tip, which enables deeper and wider lesions without the formation of coagulum on catheters. METHO...

Risks and benefits of an open irrigation tip catheter in intensive radiofrequency catheter ablation in patients with non-paroxysmal atrial fibrillation.

BACKGROUND Although open irrigation tip catheters (OITC) are effective in producing transmural radiofrequency (RF) lesions, they have the potential for fluid overload or excessive tissue damage. METHODS AND RESULTS The 203 patients with non-paroxysmal atrial fibrillation (NPAF; 85.2% males, 55.2+/-10.6 years old) who underwent RF catheter ablation (RFCA) were analyzed retrospectively. Clinica...
