Contemporary outcomes of catheter ablation of the structural ventricular tachycardias in severe ischemic and non-ischemic cardiomyopathies in Turkish population.

Introduction: Currently, there are no data regarding outcomes of the catheter ablation for structural ventricular tachycardia (VT) in Türkiye. In this observational study, we aim to investigate cardiac outcomes of patients undergoing catheter VT ablation at a tertiary center in Türkiye.

Methods: This was a retrospective observational study performed at a single university center.

Left atrial appendage orifice morphology in sickness and in health.

Background: The left atrial appendage (LAA) is the primary site of embolism in individuals with atrial fibrillation (AF). We aimed to evaluate the morphological features of the LAA orifice in patients with sinus rhythm, paroxysmal AF, and persistent AF using three-dimensional (3D) transesophageal echocardiography (TOE). We also intended to identify morphometric parameters of the LAA orifice that may be potentially associated with an increased risk of ischemic stroke.

Prognostic Nutritional Index is Associated with the Degree of Coronary Collateral Circulation in Stable Angina Patients with Chronic Total Occlusion.

Background: Coronary collateral circulation (CCC) can effectively improve myocardial blood supply to the area of CTO (chronic total coronary occlusion) and can, thus, improve the prognosis of patients with stable coronary syndrome (SCS). The degree of inflammation and some inflammation markers were associated with the development of collaterals.

Objective: To investigate whether prognostic nutritional index (PNI) has an association with the development of CCC in patients with SCS.

Long-term follow-up of patients undergoing add-on pacing/sensing lead vs. ICD lead implantation for failed IS-1/DF-1 ICD leads: a single centre experience.

Background: Intracardiac defibrillator/cardioverter (ICD) is a cornerstone device for prevention of sudden cardiac death. Lead failure (LF) is one of the most important long-term complications. In this study, we sought to investigate mid-to-long term clinical, device and lead characteristics of patients who have undergone pacing sensing lead (PSL) implantation for an ICD LF and compare them to the patients who have undergone a new ICD lead implantation.

GLP-1 Receptor Agonists and SGLT-2 Inhibitors in Patients With Versus Without Cardiovascular Disease: A Systematic Review, Meta-analysis, and Trial Sequential Analysis.

Glucagon-like peptide-1 receptor agonists (GLP1Ra) and sodium-glucose co-transporter-2 inhibitors (SGLT2i) reduce major adverse cardiovascular events (MACE). We assessed whether the effect differs in patients with and without cardiovascular (CV) disease, and rated the certainty of evidence by conducting a systematic review, meta-analysis, and trial sequential analysis of randomized controlled trials. Certainty of the evidence (CoE) was rated using the Grading of Recommendations, Assessment, Development, and Evaluation guidelines.

Electrophysiological characteristics of epicardial atrial tachycardias and endocardial breakthrough site targeting for ablation: a single center experience.

Background: Despite being increasingly observed in daily practice, epicardial atrial tachycardias (Epi AT) have not been extensively characterized. In the present study, we retrospectively characterize electrophysiological properties, electroanatomic ablation targeting, and outcomes of this ablation strategy.

Methods: Patients who underwent scar-based macro-reentrant left atrial tachycardia mapping and ablation patients with at least one Epi AT, which had a complete endocardial map, were selected for the inclusion.

A novel echocardiographic index for prediction of malnutrition in acute heart failure.

Introduction: Malnutrition is common among heart failure (HF) patients. The prognostic nutritional index (PNI) and controlling nutritional status (CONUT) are widely used for evaluation of nutritional status in HF patients. Right ventricular dysfunction, functional tricuspid regurgitation, and elevated right atrial pressure might exacerbate malnutrition by promoting bowel congestion and malabsorption in HF patients.

Evaluation of Cardiac Function in Uncomplicated COVID-19 Survivors by 2-Dimensional Speckle Tracking Imaging.

Background: COVID-19 is a multi-systemic infectious disease. Nearly 20%-30% of hospitalized patients have evidence of acute myocardial involvement, portending a poorer prognosis. However, information about the long-term effects of the disease on cardiac functions is sparse.

Procedural Characteristics, Safety, and Follow-up of Modified Right-Sided Approach for Cardioneuroablation.

Background: Cardioneuroablation is one of the emerging therapies in vasovagal syncope. In this study, we present a simple method of cardioneuroablation performed via a rightsided approach, targeting anterior-right and right-inferior ganglionated plexi, along with procedural and follow-up data.

Methods: Patients who had underwent cardioneuroablation between March 2018 and September 2019 with vasovagal syncope in 2 clinics were enrolled in the study.

Long-Term Results of Pulmonary Vein Isolation Plus Modified Posterior Wall Debulking Utilizing High-Power Short-Duration Strategy: An All-Comers Study in Real World.

Background: High-power short-duration radiofrequency ablation has improved lesion durability in pulmonary vein isolation. In this study, we investigate long-term clinical out-comes of high-power short-duration pulmonary vein isolation and posterior wall debulk- ing as an initial treatment modality in all corner atrial fibrillation patients.

Methods: This is a single-center, retrospective, observational study including all patients who have undergone high-power short-duration pulmonary vein and posterior wall deb-ulking, regardless of atrial fibrillation type and/or duration.

Association between CHARGE-AF risk score and LA mechanics: LA reservoir strain can be a single parameter for predicting AF risk.

Aims: Atrial fibrillation (AF) is a prevalent arrhythmia and the leading preventable cause of cardioembolic stroke. Scoring systems for predicting AF risk do not use imaging modalities. We sought to determine whether LA longitudinal strain could be used as a single parameter for predicting the risk of AF.

Stepwise mapping and ablation algorithm in patients undergoing ablation of unstable, unmappable scar-based atrial tachycardias.

Background: Scar based atrial tachycardia (AT)'s usually presents with a complex electrophysiological substrate. It is not uncommon that multiple instable ATs are present in a single patient. The aim of this study was to analyze clinical and electrophysiological characteristics of patients who had undergone ablation for instable ATs, and report outcomes of the stepwise substrate ablation procedure during the follow-up.

Agreement between visually estimated left ventricular ejection fraction on echocardiography and quantitative measurements using cardiac magnetic resonance.

Objective: Visual estimation of left ventricular ejection fraction (LVEF) is still used in routine clinical practice. However, most of the studies evaluating the agreement between the visually estimated LVEF (ve-LVEF) and quantitatively measured LVEF (qm-LVEF) either have not used appropriate statistical methods or gold standard imaging modality. In this study, we aimed to assess the agreement between the ve-LVEF and qm-LVEF using contemporary statistical methods and cardiac magnetic resonance imaging (CMRI).

Severe Intermittent Transvalvular Mitral Valve Regurgitation: Serious Complication of Mitral Valve Replacement With Subvalvular Preservation.

Mitral valve replacement with subvalvular preservation is a favorable technique to protect left ventricular function and improve long-term survival. However, complications of the procedure should be considered. We report the case of a patient with a history of prosthetic mitral valve replacement with severe intermittent transvalvular mitral regurgitation and reduced ejection fraction.

Invasive validation of the left ventricular global longitudinal strain for estimating left ventricular filling pressure.

Purpose: An elevated left ventricular (LV) filling pressure is the main finding in heart failure patients with preserved ejection fraction, which is estimated with an algorithm using echocardiographic parameters recommended by the recent American Society of Echocardiography (ASE)/European Association of Cardiovascular Imaging (EACVI) guidelines. In this study, we sought to determine the efficacy of the LV global longitudinal strain (GLS) in predicting an elevated LV filling pressure.
