At Abbott, our goal is to advance the treatment of cardiac arrhythmias with innovations that improve both cost savings and clinical outcomes.
In an independent head-to-head bench test comparison with the ThermoCool SmartTouch SF catheter, TactiCath Quartz contact force ablation catheter showed higher accuracy in both axial (perpendicular) and parallel (lateral) orientations.10
Data from studies such as TOCCATA, EFFICAS I and EFFICAS II show that contact force (CF) sensing is not only safe for use in pulmonary vein isolation (PVI) but also associated with lower rates of PV reconnection and atrial fibrillation (AF) recurrence.1-4 As the cost of care has been reported to increase approximately four times in the first year after ablation for patients with repeat ablations, increased effectiveness of single ablation procedures for AF could substantially decrease health care costs for patients undergoing these procedures.8, 9
The purpose of the TOCCATA clinical trial was to evaluate the safety and efficacy of CF sensing during ablation procedures.1, 2
EFFICAS is a pair of studies to (I) identify and (II) validate CF recommendations to ensure pulmonary vein isolation.
Read more about the EFFICAS II study.
The TOCCASTAR trial (TactiCath Contact Force Ablation Catheter Study for Atrial Fibrillation) is the only prospective, randomized, controlled, multicenter study conducted to date to evaluate the safety and effectiveness of a contact force sensing ablation catheter for the treatment of symptomatic paroxysmal AF.5
Key Takeaways:
Read comprehensive information on these clinical studies:
A recent publication by Moussa Mansour et al. demonstrates that for patients undergoing repeat ablations, the cost of care increases approximately four times—to $52,821—in the first year after ablation and remained forty-six percent higher, even when excluding the cost associated with the additional ablation procedures.9
Another analysis showed that the use of optimal contact force guided AF ablationa with the TactiCath™ Quartz catheter resulted in fewer post ablation clinical events, translating to a 15-percent reduction in post ablation management costs ($3,402 savings per patient) in the year after ablation, compared with patients who were treated with a non-contact force ablation catheter.8

TactiCath Quartz Ablation Catheter
Rx Only
Brief Summary: Prior to using these devices, please review the Instructions for Use for a complete listing of indications, contraindications, warnings, precautions, potential adverse events and directions for use.
Indications: The TactiCath Quartz Contact Force Ablation Catheter is indicated for use in cardiac electrophysiological mapping and for the treatment of drug refractory recurrent symptomatic paroxysmal atrial fibrillation, when used in conjunction with a compatible RF generator and three-dimensional mapping system.
Contraindications: Do not use for any of the following conditions: certain recent heart surgery; prosthetic valves; active systemic infection; use in coronary vasculature; myxoma or intracardiac thrombus, or an interatrial baffle or patch; retrograde trans-aortic approach in patients with aortic valve replacement.
Warnings: It is important to carefully titrate RF power; too high RF power during ablation may lead to perforation caused by steam pop. Contact force in excess of 70 g may not improve the characteristics of lesion formation and may increase the risk for perforation during manipulation of the catheter. Patients undergoing septal accessory pathway ablation are at risk for complete AV block which requires the implantation of a permanent pacemaker. Implantable pacemakers and implantable cardioverter/defibrillator may be adversely affected by RF current. Always verify the tubing and catheter have been properly cleared of air prior to inserting the catheter into the vasculature since entrapped air can cause potential injury or fatality. The temperature data transmitted by the sensor in this catheter is representative of the irrigated electrode only and does not provide tissue temperature data.
Precautions: The long-term risks of protracted fluoroscopy and creation of RF induced lesions have not been established; careful consideration must be given for the use of the device in prepubescent children. When using the catheter with conventional EP lab system or with a 3D navigational system, careful catheter manipulation must be performed, in order to avoid cardiac damage, perforation, or tamponade. Always maintain a constant saline irrigation flow to prevent coagulation within the lumen of the catheter. Access the left side of the heart via a transseptal puncture. Care should be taken when ablating near structures such as the sino-atrial and AV nodes.
Potential Adverse Events: Potential adverse events include, but are not limited to, cardiovascular related complications, including groin hematoma, pericardial effusion and infection. More serious complications are rare, which can include damage to the heart or blood vessels; blood clots (which may lead to stroke); tamponade; severe pulmonary vein stenosis; heart attack; esophageal fistula, or death. Please refer to the Instructions for Use for a complete list.
