A 21-year-old man, known case of the repaired congenital heart disease, developed complete atrioventricular block (AVB) one week after simultaneous bioprosthetic pulmonary and tricuspid valve replacement and atrial septal defect repair. Considering the persistence of the AVB, it was decided to implant a permanent pacemaker. After considering all available options and the issues related to the patient, it was decided to implant a leadless pacemaker (LLP).

Predicting the success of catheter ablation is crucial for patient selection and management. This research seeks to create a machine learning model to forecast the early recurrence of atrial fibrillation following catheter ablation.

This study assessed appropriateness of anticoagulation in anticoagulation-naive AF patients treated with DOACs during a 12-month prospective follow-up.
Methods: This prospective cohort study included all anticoagulation-naive AF patients referred for anticoagulation for stroke prevention at a tertiary cardiovascular center.
Background: Chronic diseases, such as heart failure with reduced ejection fraction (HFrEF), remain significant factors in the healthcare burden in Iran. Healthcare systems must have comprehensive data on the current usage, costs, and quality of care to tackle these challenges and formulate strategic plans effectively.
Methods: The study included 209 patients with a mean age of 58 years (SD = 16.
Background: Pulsed-field ablation (PFA) is a cutting-edge technique that employs non-thermal energy to cause cell death by inducing irreversible electroporation of cell membranes. This systematic review evaluates the PFA effectiveness as a potential alternative to radiofrequency and cryo-ablation for treating ventricular tachycardia.
Methods: PubMed, Embase, Scopus, and Web of Science were systematically searched using keywords related to ventricular tachycardia and pulsed-field ablation.
Background: Atrial fibrillation (AF) augments the risk of stroke by 4-5 times. Vitamin D is pivotal in numerous metabolic pathways. A handful of studies have explored the correlation between vitamin D deficiency (VDD) and AF outcomes.

Patients with SHD are particularly susceptible to VT, a condition that increases the risk of sudden cardiac death (SCD). Implantable cardioverter-defibrillators (ICDs) can terminate VT and prevent SCD but do not prevent VT recurrence.

Methods: In this prospective longitudinal cohort study, consecutive patients with a diagnosis of AF were initially evaluated.

Background: Recent studies investigating the effects of fish oil on shocks administered by ICDs in patients with ventricular tachycardias produced inconclusive results. This systematic review aims to evaluate the effectiveness of omega-3 polyunsaturated fatty acids in lowering the risk of life-threatening VTs among individuals with implantable cardioverter-defibrillators.
Methods: We searched five databases, including Central, PubMed, EMBASE, Web of Science, and Scopus, for studies evaluating the efficacy of omega-3 polyunsaturated fatty acids (PUFAs) for the prevention of ICD events for VT or VF, published up to December 1, 2023.

Background: Brugada syndrome (BrS) is characterized by ST-segment elevation in the right precordial leads, which is not explained by ischemia, electrolyte disturbances, or obvious structural heart disease.
Aim: In present study, we aim to evaluate presentation, long-term outcome, genetic findings, and therapeutic interventions in patients with BrS.
Methods: Between September 2001 and June 2022, all consecutive patients with diagnosis of BrS were enrolled in the present study.
Background: The majority of cardiac disorders resulting from ventricular dysrhythmias are fatal. The Implantable Cardioverter Defibrillator (ICD) is one of the most common treatments of ventricular dysrhythmias. Despite the benefits of ICD in preserving life, patients with ICD experience adverse physical, psychological, and social consequences.

We conducted a nationwide survey to assess these measures in Iran as a developing country. To present the protocol for the Iran Quality of Care in Medicine Program (IQCAMP) study, which estimates the quality, cost, and utilization of health services for seven diseases in Iran.

The purpose of this study was to evaluate the role of ECG in differentiating between obstructive (OHCM) and non-obstructive (NOHCM) HCM.
Methods: The present study is a cross-sectional analysis of HCM patients referred to our center between 2008 and 2017.
The catheter ablation of idiopathic ventricular arrhythmias is accepted as a first-line treatment as it successfully eliminates about 90.0% of such arrhythmias. One of the most challenging ventricular arrhythmias originates from the left ventricular summit (LVS), a triangular epicardial space with the left main bifurcation as its apex.

We aimed to review studies on the economic evaluation of adding dapagliflozin to standard care compared with standard care alone in heart failure patients with reduced ejection fraction (HFrEF).
Methods: For this systematic review, the PubMed, EMBASE, Web of Science, Cochrane, Scopus, and CEA Registry scientific databases were searched from 1 January 2020 to 25 March 2022.
Introduction: Epicardial pacemakers are known as an alternative for endocardial pacemakers in some cases such as heart block, and complex congenital heart diseases. Considering recent advances and improvement of epicardial lead subtypes, it is essential to investigate the long-term function of them. In this study, we aimed to assess the sensing and pacing characteristics, and survival of bipolar steroid-eluting and unipolar nonsteroid-eluting epicardial pacemakers.

Atrial fibrillation(AF) is the most common cardiac arrhythmia in the world that is associated with significant morbidity and mortality. This study assessed cost-effectiveness studies of novel oral anticoagulants(NOACs) compared to Warfarin for the prevention of stroke in patients with AF in LMICs.

Methods And Results: In this pilot RCT, 40 patients were randomized to rivaroxaban 20 mg daily or warfarin. No patients experienced symptomatic ischemic strokes and systemic embolic events (the primary composite study outcome) during a 12-month follow-up.
Atrial fibrillation (AF) is a morbid and heritable irregular cardiac rhythm that affects about 2%-3% of the population. Patients with early-onset AF have a strong genetic association with the disease; nonetheless, the exact underlying mechanisms need clarification. We herein present our evaluation of a 2-generation Iranian pedigree with early-onset AF.
