Radiofrequency ablation in patients with obstructive hypertrophic cardiomyopathy: An updated comprehensive review and meta-analysis.

Background: Radiofrequency catheter ablation (RFCA) has emerged as a therapeutic option for surgical myectomy and alcohol septal ablation (ASA) in patients with hypertrophic obstructive cardiomyopathy (HOCM), but its efficacy remains unclear.

Aim: Due to limited research on RFCA for HCM, there is an ongoing attempt to assess its efficacy and safety.

Methods: PubMed, Embase, and Scopus were systematically searched for studies assessing the efficacy outcomes for patients with HOCM who underwent RFCA.

Primary Retroperitoneal Lymph Node Dissection for Clinical Stage II A/B Seminomas: A Systematic Review and Meta-Analysis.

Introduction: Chemotherapy and radiation therapy are considered standard treatments for stage II seminoma patients; however, these therapies are associated with long-term toxicities. Recently, retroperitoneal lymph node dissection has emerged as an alternative strategy, and the first three phase II trials were published in 2023 with promising results. The present study conducted a systematic review and meta-analysis to evaluate this surgery as an alternative treatment for stage IIA/B seminoma patients.
