Combined ethanol and radiofrequency ablation for the elimination of focal atrial tachycardia originating from the Marshall bundle.

Introduction And Importance: Atrial tachycardias (AT) originating from the Marshall bundle (MB) are rare and present significant challenges in diagnosis and management. The authors present the case of a 29-year-old male with recurrent AT successfully treated with a combined ethanol and radiofrequency ablation approach. This case highlights the effectiveness of this dual ablation strategy in resolving AT originating from the MB, contributing valuable insights into managing complex AT cases.

A personalized aortic valve replacement using computed tomography-guided aortic valve neocuspidization. Analysis of mid-term results compared to standard Ozaki technique.

Background: The original Ozaki technique involves sizing the neovalve cusps during cross-clamp. It leads to prolonging the ischemic time compared to standard surgical AVR. Measurements taken on the collapsed Aortic Root (AR) may also be inaccurate.

Computed tomography-guided aortic valve neocuspidization: details of preoperative assessment and surgical technique.

The original Ozaki technique involves sizing and trimming the neovalve cusps during cross-clamp. It leads to prolongation of the ischaemic time, as compared to standard aortic valve replacement. We use preoperative computed tomography scanning of the patient's aortic root to develop personalized templates for each leaflet.

Pulmonary valve neocuspidization and tricuspid valve replacement in intravenous drug abusers with infective endocarditis: Report of two cases.

Right-sided infective endocarditis accounts for 5-10% of endocarditis cases. It occurs predominantly among intravenous drug abusers. The pulmonary valve is involved in fewer than 2% of patients with endocarditis.

[EFFICACY OF RADIOFREQUENCY ABLATION OF AORTORENAL SYMPATHETIC NODES IN PATIENTS IN ARTERIAL HYPERTENSION].

Efficacy of radiofrequency ablation (RFA) of prevertebral sympathetic nodes, concern- ing the arterial pressure lowering in 36 patients, suffering hypertonic disease and coex- istent heart diseases, was analyzed. In 12 mo after RFA a systolic arterial pressure lowering at average throughout the group by (3.24 ± 1.
