After cryoablation, patients are seen for follow-up, including mammograms, every six months for the first five years, and then have annual visits, explains Dr.
Medical ablation involves removal of a part of biological tissue or aberrant tissue from within the body via minimally invasive procedures, usually by using percutaneous chemical ablation, radiofrequency ablation, irreversible electroporation, cryoablation, microwave ablation, high-intensity-focused ultrasound ablation equipment.
(5,6) Also, different LTA types of energy (for example, cryoablation, radiofrequency, or microwaves) and approaches (percutaneous, laparoscopic, or open) can be chosen depending on the institution's experience.
International contributors discuss the role for focal therapy in maximizing survival while minimizing morbidity; focal therapy and minimally-invasive therapies instead of radical prostatectomy to achieve that balance; considerations in conservative management; new trends in imaging and treatment options (e.g., the latest cryoablation techniques, photodynamic therapy for focal ablation); factors that affect patients' choice of treatments; and assessment of treatment efficacy.
Radiofrequency ablation is the current ablative method of choice, although other techniques, including microwave ablation, laser ablation, and cryoablation, are also available.
WIDENING APPLICATIONS FOR CRYOABLATION. For the first study, cryotherapy was used to treat 13 breast cancer patients who had refused invasive surgery.
Adding to its AF portfolio, Medtronic also recently purchased Montreal, Canada-based CryoCath Technologies, Inc., a leader in cryoablation treatments for atrial fibrillation, for $380 million.
Balloon catheterization in AF comprises three technologies: cryoablation, ultrasound ablation, and laser ablation.
An existing surgical technique called ablation can treat it--but an emerging technology called cryoablation could make the procedure less uncomfortable, says Bruce D.
"Medtronic's offer reflects its endorsement of our cryoablation technology and the role that our flagship product, Arctic Front, will play in treating atrial fibrillation patients around the world," said CryoCath Chief Executive Jan Keltjens.
Arctic Front, the company's lead product for the treatment of paroxysmal atrial fibrillation (PAF), is a unique cryoablation balloon catheter that allows physicians to safely and effectively isolate all four pulmonary veins in the treatment of PAF.
-- The majority of a federal advisory panel recommended that a cryoablation system be approved for treating atrial flutter in adults, under certain conditions that include a postmarketing study of treatment recipients conducted by the manufacturer to further evaluate its safety and efficacy.
