A new magnetic-guided catheter has successfully treated atrial fibrillation in 38 of 40 patients, with no reported complications. The robotic device offers more precise control than conventional catheter ablation devices, potentially reducing procedure duration and improving outcomes.
A study published in the New England Journal of Medicine found that radiofrequency catheter ablation significantly improved heart rhythm and quality of life for patients with chronic atrial fibrillation. The procedure was effective in returning 74% of patients to normal rhythm, even in those with difficult-to-treat cases.
Researchers at Johns Hopkins Medicine successfully used a 3D map of the heart to perform cardiac ablation, eliminating the need for radiation exposure and improving patient safety. The technique used sensor-guided catheter and electro-anatomic mapping to precisely target diseased heart tissue.
Duke engineers have developed a new ultrasound device that combines 3-D imaging with therapeutic heating, potentially improving doctors' most widely used method for destroying aberrant tissue in the heart. The device uses sound waves to heat tissue from a distance, eliminating the need to physically touch the tissue.
A new study published in the American College of Radiology shows that expandable electrodes are safe and effective for radiofrequency ablation of liver tumors. The procedure resulted in high survival rates and low complication rates, comparable to those achieved through surgery.
Researchers found that ablation therapy extended median survival to 33 months compared to 20 months for chemotherapy-only treatment. The study also showed improved disease recurrence rates and overall 3-year survival rate of 51%.
Researchers found that RF ablation was a safe and effective treatment option for early-stage liver cancer patients, with survival rates comparable to surgical resection. The procedure proved more successful with smaller tumors, offering a viable alternative for inoperable patients.
A study published in Pacing and Clinical Electrophysiology journal confirms catheter ablation is safe for patients, with no significant damage to cardiac nerves. The procedure is now a standard therapy for various arrhythmias, including SVT, atrial fibrillation, and AV nodal re-entrant tachycardia.
Researchers studied 155 image-guided RFA lung procedures on 126 medically inoperable patients with 163 lesions, finding low complication rates and improved morbidity. The outpatient procedure effectively controls small tumors, allowing patients to avoid surgery and improve their quality of life.
Researchers found RFA improves quality of life for inoperable lung cancer patients, with complete ablations resulting in tumor size reduction and minimal enhancement on follow-up CT. Pattern enhancement and changes in tumor size are key indicators of successful RFA on CT.
A new study published in the Journal of Cardiovascular Electrophysiology found radiofrequency ablation to be a safe and effective treatment for children with various forms of heart problems. The procedure showed high success rates, with over 98% of patients able to be cured, regardless of demographics or specific disorder location.
A worldwide survey of catheter ablation for atrial fibrillation found varying methods, effectiveness, and complications. The study reported a significant increase in procedures, but also noted major complications such as early deaths, strokes, and tamponade.
In a study of 18 patients with inoperable lung tumors, radiofrequency ablation (RFA) was found to eradicate lung tumors with no relapse in 94% of cases. Minor complications, including pneumothorax, were treated successfully, and the procedure offered benefits such as low costs, short hospitalization times, and good patient tolerance.
A new treatment using radiofrequency ablation has been shown to be effective in eliminating kidney tumors, with complete ablation achieved in 83% of patients. The treatment is particularly promising for patients who are not ideal candidates for surgery due to other health-related conditions.
Researchers successfully treated 21 small breast cancers with RF ablation, destroying malignant tissue with no adverse effects. However, surrounding tissue was not removed, limiting the procedure's effectiveness as a standalone treatment.
The PAVE study found that biventricular pacing improved cardiac function and functional capacity in patients with chronic atrial fibrillation undergoing ablate and pace therapy. In contrast, the DINAMIT study showed no overall mortality benefit of implantable cardioverter defibrillator (ICD) therapy in patients following a recent acute...
Researchers from Michigan Medicine report dramatic success in treating atrial fibrillation patients using radiofrequency catheter ablation, achieving high cure rates and low complication rates. The technique involves delivering intense radiofrequency waves to specific areas of disorganized electrical activity, resulting in a significan...
Researchers treated 18 patients with lung nodules using radiofrequency ablation, achieving a 97% destruction rate. The treatment was found to be short-lasting and manageable, with most complications resolved within a week.
Researchers report successful treatment of 50 out of 51 renal tumors using radiofrequency ablation. The therapy is particularly effective for tumors on the outer surface of the kidney due to surrounding fat insulation.
Radiofrequency ablation has shown promising results in treating advanced lung cancer, with significant pain reduction and improved survival rates. The procedure involves using extreme heat to destroy or slow the growth of tumors, and can be used as an alternative to surgery, chemotherapy, and radiation therapy.
The Mayo Clinic study shows RF ablation can effectively kill cancer cells causing bone pain, with 95% of patients experiencing significant pain relief. The procedure takes 30-60 minutes and alleviates pain by killing nerve endings and cancer tissue.
Researchers developed a new MRI-guided catheter ablation technique to treat arrhythmia, reducing radiation exposure and improving procedure accuracy. The novel method uses MRI to guide radio frequency energy, creating precise lesions that block abnormal electrical pathways in heart muscle.
