Improvement of Pulmonary Function in Heart Failure Patients with Restrictive Patterns Undergoing Transcatheter Aortic Valve Replacement.

Background: This study aimed to investigate the improvement of pulmonary function in heart failure patients with restrictive patterns undergoing transcatheter aortic valve replacement (TAVR).

Methods: A total of 80 patients with heart failure and restrictive patterns undergoing TAVR due to severe aortic stenosis were included in this study. Spirometry and gas diffusion were assessed before and 4-6 months after TAVR.

Impact of atrial flow regulator (AFR) implantation on 12-month mortality in heart failure : Insights from a single site in the PRELIEVE study.

Background: Implantation of the atrial flow regulator (AFR) to create an interatrial left-to-right shunt has been shown to be safe and feasible to reduce intracardiac filling pressures in patients with heart failure (HF).

Objectives: We aimed to assess the effect of AFR implantation on 12-month mortality and hospitalization rates in patients with reduced (HFrEF) or preserved HF (HFpEF).

Methods: One-year follow-up data from 34 subjects enrolled at a single PRELIEVE center were analyzed.

Impact of Antecedent Aspirin Use on Infarct Size, Bleeding and Composite Endpoint in Patients with de Novo Acute Myocardial Infarction.

Background: The study aimed to evaluate the impact of antecedent aspirin use on infarct size, bleeding and composite endpoint in patients with de novo acute myocardial infarction.

Patients And Methods: A total of 562 consecutive patients with de novo acute myocardial infarction were included in this prospective cohort study. Patients were assigned into two groups based on presence (n=212) and absence (n=350) of prior aspirin use.

Correlation between apnea-hypopnea index and Tp-Te interval, Tp-Te/QT, and Tp-Te/QTc ratios in obstructive sleep apnea.

Background: Obstructive sleep apnea (OSA) is a highly prevalent sleep disorder associated with important cardiovascular complications including ventricular arrhythmias. Tp-Te interval, Tp-Te/QT, and Tp-Te/QTc ratios are repolarization indices representing ventricular arrhythmogenic potential. These parameters are associated with ventricular arrhythmias and sudden cardiac death.

The effect of 5-day course of hydroxychloroquine and azithromycin combination on QT interval in non-ICU COVID19(+) patients.

Background: The combination of Hydroxychloroquine (HCQ) and azithromycin showed effectiveness as a treatment for COVID-19 and is being used widely all around the world. Despite that those drugs are known to cause prolonged QT interval individually there is no study assessing the impact of this combination on electrocardiography (ECG). This study aimed to assess the impact of a 5-day course of HCQ and azithromycin combination on ECG in non-ICU COVID19(+) patients.

Predictive role of ventricular repolarization parameters for the occurrence of complete heart block in patients undergoing transcatheter aortic valve implantation.

Background: We investigated the role of ventricular repolarization parameters to predict complete atrioventricular block in patients undergoing transcatheter aortic valve implantation (TAVI).

Methods: A total of 150 patients undergoing TAVI due to severe aortic stenosis were included in this retrospective cohort study. Patients were assigned in two groups based on the presence (n: 49) or absence (n: 101) of complete atrioventricular block after TAVI.

Assessment of the Relationship between Monocyte to High-Density Lipoprotein Ratio and Myocardial Bridge.

Background: Assessing the monocyte to high-density lipoprotein ratio (MHR) is a new tool for predicting inflamation, which plays a major role in atherosclerosis. Myocardial bridge (MB) is thought to be a benign condition with development of atherosclerosis, particularly at the proximal segment of the brigde.

Objective: To evaluate the relationhip between MHR and the presence of MB.

The prognostic value of fragmented QRS in patients undergoing transcatheter aortic valve implantation.

Background: Although transcatheter aortic valve implantation (TAVI) can successfully correct aortic narrowing, pre-existing pathophysiological alterations in the left ventricle are still a concern in terms of long-term mortality. This study aimed to examine the predictive role of fQRS morphology on long-term prognosis in patients undergoing TAVI due to severe aortic stenosis.

Methods: A total of 117 patients undergoing TAVI due to severe aortic stenosis were included in this retrospective cohort study.

Turkey: coronary and structural heart interventions from 2010 to 2015.

Growing populations and ageing demographics lead to an increased burden of ischaemic heart disease and related cardiovascular interventions, resulting in pressure on healthcare systems. Although the healthcare system in Turkey has undergone comprehensive remodelling over the last decade, there are many challenges to overcome, including better reimbursement for cardiovascular interventions, standardisation of interventional cardiology services and research-related activities. In this manuscript, we present an overview of coronary and structural heart interventions in Turkey, as well as providing information on current reimbursement policies and the healthcare system.
