Predictors of Failure Cardioversion for Recurrent Atrial Fibrillation Following Mitral Valve Surgery With Ablation

Background: After surgical radiofrequency ablation in patients undergoing mitral valve surgery, an electrical cardioversion machine is often needed for ending recurrent atrial fibrillation. In this research, we looked for potential predictors of failed ECV for recurrent atrial fibrillation after mitral valve surgery with concomitant radiofrequency ablation. Methods: We accepted 1,136 patients with a history of mitral valve surgery and concomitant radiofrequency ablation. Patients with failed ECV and high ECV were compared between patients with failed ECV and healthy ECV. According to receiver operating characteristic curve analysis, the best threshold values for predicting failed ECV were 55. 5 years, 64. 5 mm, and 90. 5 days. Conclusion: In this group, the older age, larger left atrium, and longer time from surgery to ECV are all predictors of poor ECV.

Assessment of Bipolar Radiofrequency Ablation Combined with Coronary Artery Bypass Surgery for Management of Atrial Fibrillation in Cardiac Patients

Complete transmural ablation lines are obtained through AF ablation, and reduces the chance of treatment failure. We investigated the effectiveness of BRA for sinus rhythm recovery in patients with AF/CABG. Methods: Patients with permanent or paroxysmal AF were scheduled for BRA, CABG, and CABG in our center from May 2014 to June 2020. After BRA with CABG, we found that group II patients had higher sinus rhythm recovery rates after BRA with CABG than group I patients. Overall mortality in group II patients was significantly lower than in group I patients. The Cox hazards survival regression ratio's 95% confidence interval was significantly different between groups. AF precursors of chronic recurrent post-BRA recurrent AF were discovered long-term AF before BRA with CABG and permanent AF types.

Laser ablation after stereotactic radiosurgery: a multicenter prospective study in patients with metastatic brain tumors and radiation necrosis

Laser Ablation in Patients with radiographic decline following stereotactic radiosurgery of brain metastases has been a multicenter prospective study of laser interstitial thermal ablation in patients with radiographic progression following stereotactic radiosurgery of brain metastases. This report included patients with a Karnofsky Performance Scale score of u2265-60, an age > 18 years, as well as surgical eligibility. The median baseline KPS score was 85, while the median age was 60 years, 64% of the subjects, and 64% of the subjects were female. There was no significant difference in the length of stay between the recurrent tumor and radiation necrosis patients. After surgery, thirty percent of patients were expected to stop or reduce steroid use by 12 weeks. The Adverse events were also similar for both groups, with no significant difference in the overall event rate. Compared to the recurrent tumor or tumor progression patients, there was a 12-week PFS and OS advantage for the radiation necrosis patients. No. clinical trial registration is available.

Stereotactic laser ablation as treatment for brain metastases that recur after stereotactic radiosurgery: a multiinstitutional experience

OBJECTIVE METHASTES recur after stereotactic radiosurgery are rare. METHODS The authors explore the collective experience of four institutions where the surgical laser ablation of BMs that recurred after SRS was performed with stereotactic laser ablation resurgently. All cases of progression were observed in BMs in which 80% ablation was achieved, but no disease progression was observed in BMs in which 80% ablation was achieved. Despite ablation rates of 80%, no disease progression was observed in these patients, indicating that adjuvant hypofractionated SRS enhances SLA's effectiveness. Of the 23 SLA-treated patients, three developed transient hemiparesis, 1 developed hydrocephalus requiring temporary ventricular drainage, and one patient who underwent SLA of a 28. 9-cm 3 lesion required an emergency hemicraniectomy. CONCLUSIONS Stereotactic laser ablation is a safe treatment option for BMs in which SRS fails.

Conservative surgery with microwave ablation for recurrent bone tumor in the extremities: a single-center study

Abstract Background: Recurrent bone tumors in the extremities that have been present in the extremities persist, and surgery for these tumors is a challenge. This research was designed to assess the medical effects of microwave ablation in the treatment of recurrent bone tumors. Methods We currently have 15 patients who underwent microwave ablation for recurrent bone tumors within the past 7 years. Percutaneous microwave ablation of one patient with osteoid osteoma and another with bone metastasis resulted in postoperative pain relief. Three patients with tumor metastasis and died, while the remaining 8 patients with the disease survived.
