This was a prospective single centre study which included 36 consecutive patients who underwent radiofrequency catheter ablation (RFCA) of symptomatic paroxysmal AF at cardiology department in Ain shams university hospitals during the period from 2015 till 2017. Exclusion criteria included patients unwilling to give study consent and those with persistent AF, history of organized atrial tachycardia (AT) or atrial flutter (AFL), or previous history of AF ablation.Trans-oesophageal echocardiography was performed in all patients to rule out left atrial (LA) thrombus before ablation. In patients on

This study aims to determine the incidence of atrial fibrosis in patients with non-valvular AF and its impact on recurrence after pulmonary vein antrum isolation. Patients and methods:This study enrolled 30 patients referred to the cardiology department at Ain Shams University hospitals for first-time pulmonary vein antrum isolation for the treatment of symptomatic paroxysmal nonvalvular AF. Of these patients catheter ablation was postponed in 2 patients because of the development of cardiac tamponade during transseptal puncture, thus the 28 patients were included in the study.All patients included were free of hypertension, diabetes mellitus, coronary artery disease, and cardiomyopathy thus they were defined as having lone AF. Inclusion criteria included patients with symptomatic paroxysmal atrial fibrillation who were younger than sixty years and AF was documented by 12 lead ECG or Holter monitoring.Exclusion criteria included patients with history of previous pulmonary vein isolation, patients with history of previous cardiac ablation procedures, patients with history of previous cardiac surgery, patients with persistent or permanent AF and patients with valvular heart disease.After giving informed written consent and approval of the ethical committee, the selected patients were subjected to the

During ablation of re-entrant ventricular tachycardia (VT) 3-dimensional mapping systems are now used to properly delineate the scar tissue and aid ablation of scar-related VT. The aim of our study was to outline how the mode of ablation predicts success and recurrence in large scar-related VT. When comparing patients with recurrence and patients with no recurrence, univariate analysis showed that number of ablation lesions (28 ± 8 vs. 12 ± 8, P = 0.01) and more linear ablation lesions rather than focal lesions (P = 0.03) were associated with long-term success. We demonstrated that more extensive ablation lesions and creation of linear lesions is associated with better success rate and lower recurrence rate during ablation of large scar-related ventricular tachycardia.

This study was prospectively conducted on 31 difficult-to-wean mechanically ventilated COPD patients in Respiratory ICUs of Ain Shams University Hospitals. Diagnosis of COPD was based upon: clinical, radiological and arterial blood gas (ABGs) analysis. Prior spirometric results were included if available. 5 The patient was
