Background: The prevalence of coronary chronic total occlusion (CTO) in coronary angiography (CAG) has risen with ageing populations, along with the expansion of CTO percutaneous coronary interventions (CTO-PCI). However, CTO-PCI encounters challenges such as undersized stents, dissection risks, and limited access to intravascular imaging (IVI), particularly in regions with limited health budgets. This study introduces the 'GIVE IT TIME TO SOBER UP - GITSU strategy', a two-session CTO-PCI approach where Thrombolysis in Myocardial Infarction (TIMI-3) antegrade flow is achieved without stent placement in the first session.

Article Synopsis
  • - The study investigates how collateral vessels, which develop from arterioles due to arterial issues, may provide a natural bypass to improve walking performance in patients with peripheral arterial disease after treatments like balloon angioplasty.
  • - It analyzed medical data from 824 patients undergoing endovascular treatments for femoropopliteal chronic total occlusion, ultimately focusing on 410 limbs and looking at the relationship between collateral vessels and vessel dissection severity.
  • - Results indicate that severe dissections were more common with specific lesion types, longer occlusions, and certain characteristics of collateral vessels, suggesting that these factors could help predict complications following treatment.

Background/aim: The distinctive liver framework is converted into structurally abnormal nodules as a consequence of tissue fibrosis in cirrhosis. Cardiac dysfunction in cirrhosis was described, and the term "cirrhotic cardiomyopathy (CCM)" was coined to describe this syndrome. Recent research has shown that the contractile characteristics of the right ventricular outflow tract (RVOT) have a significant impact on right ventricular functions.

Aim: Recent research has demonstrated that the contractile characteristics of the right ventricular outflow tract (RVOT) play a significant role in right ventricular function. Pulmonary annular motion velocity (PAMVUT) is a reliable marker of RVOT function. Also, combined systolic velocity [PAMVUT added to tricuspid annular systolic velocity (St)] has been revealed as a suitable parameter for right ventricular systolic function.

Background: Rotational atherectomy (RA) may cause bradyarrhythmias and transitory atrioventricular block when performed in the right coronary artery (RCA) or a dominant circumflex (CX) coronary artery. However, there are no studies of a solution that can prevent coronary flow deterioration and bradycardia complications that may occur during RA. We aimed to create an alternative rota-flush solution to minimize the risk of bradycardia and complete atrioventricular block (AVB) that can occur during RA.

Transradial Access (TRA) is the suggested method when performing coronary procedures. TRA has several advantages over the transfemoral approach, but also some restrictions. The present study compared the efficacy and safety of the traditional proximal transradial approach (pTRA) with a newer technique known as the distal transradial approach (dTRA) for performing a coronary angiography (CAG) and percutaneous coronary intervention (PCI).

Purpose: For assessing the severity of tricuspid regurgitation (TR), there is no gold standard. We developed a parameter, the right ventricular systolic force ratio-RIVIERA, using the continious wave Doppler analysis of TR and pulsed-wave analysis of the right ventricle outflow tract. We hypothesized that the RIVIERA would facilitate the ability to identify severe TR in clinical settings.

Background: One of the greatest challenges in the diagnosis of acute mesenteric ischemia (AMI) is the lack of specific laboratory tests that support multidetector computed tomography (CT). Our aim is to investigate the diagnostic value of electrocardiographic QT parameters in AMI and their relationship with CT findings.

Materials And Methods: Patients who were admitted to the emergency department with abdominal pain were recruited retrospectively from the hospital information system.

Diabetes, hypertension, hyperlipidemia and smoking are associated with coronary artery disease and ST-elevation myocardial infarction (STEMI). However, patients without any classic risk factors have a higher mortality rate in the post-STEMI period. The aim of this study was to investigate the relationship between in-hospital mortality and creatinine/albumin ratio in patients with STEMI without modifiable risk factors.

Introduction: Data regarding the possible role of heparanase (HPA) in the occurrence of left atrial/left atrial appendage (LA/LAA) thrombus in patients with atrial fibrillation (AF) is lacking. The goal of the present study was to assess the association between plasma levels of HPA and LA/LAA thrombus in AF.

Methods: A total of 687 patients with nonvalvular AF (NVAF) without anticoagulation therapy were included from January 2016 to June 2019.

Purpose: Acute pulmonary embolism is a life-threatening cardiothoracic emergency leading to right ventricle systolic and diastolic dysfunction. In the present study, we investigated the right ventricle diastolic function and its predictive value in patients with acute pulmonary embolism.

Material And Methods: Were prospectively recruited in this study 621 patients diagnosed with acute pulmonary embolism between December 2015 and June 2019.

Article Synopsis
  • The study investigates the simple right ventricular contraction pressure index (sRVCPI) as a new echocardiographic measure to assess right ventricular function and its relationship with mortality in acute pulmonary embolism (APE).
  • 116 APE patients underwent assessment using the pulmonary embolism severity index (PESI), revealing that higher sRVCPI values were linked to increased mortality, with a notable cut-off level suggesting predictive accuracy.
  • Results indicated a strong inverse correlation between sRVCPI and PESI scores, suggesting that sRVCPI could serve as a useful tool for estimating short-term mortality risk in APE patients.

Introduction: Acute pulmonary embolism (APE) is an emergent cardiothoracic disorder. The PESI score is used to estimate 30-day mortality in patients diagnosed with non-high-risk APE. Also, there are biomarkers for predicting prognosis and mortality in APE.

Purpose: Acute pulmonary embolism (APE) is a life-threating cardiothoracic thromboembolic emergency in which right ventricle dysfunction (RVD) is a major concern. In the present study, we examined the hepatic veins (HVs) blood flow with pulsed-wave spectral Doppler ultrasonography to determine its relationship with the simplified pulmonary embolism severity index (sPESI) and the patient's RVD status.

Methods: We divided the 243 patients who met the inclusion criteria into two groups based on both their sPESI scores and their RVD status.

Introduction: Acute pulmonary embolism (APE) is a cardiothoracic thromboembolic emergency at risk of life-threatening. Several risk graduation algorithms may be applied to delineate short-term mortality in patients with APE. In this study, we aim to depict the relationship between the right ventricular early inflow-outflow (RVEIO) index, which is a Doppler-based parameter, and the pulmonary embolism severity index(PESI) in acute pulmonary embolism.

Introduction: The non-O phenotype of the ABO genotype has been linked with an increased risk of cardiovascular disease. Atrioventricular (AV) block (AVB) is defined as retardation or cessation in the route of an electrical impulse passing from the atria to the ventricles because of an anatomical or functional disruption in the conduction system. We aimed to interpret the association between blood group status and high-grade atrioventricular block (HAVB).

Background And Aim: The objective of this study was to assess the potential role of mitral regurgitation (MR) in the release of copeptin in heart failure patients with reduced ejection fraction (HFrEF).

Methods: The study included 63 patients of whom 33 had functional mild MR (Group 1) and 30 had functional severe MR (Group 2). The functional class of both groups was New York Heart Association (NYHA) Class III.

Behçet's disease (BD) is an autoimmune disorder affecting multiple organs. Aortic pseudoaneurysm is the most catastrophic lesion in BD. This lesion type is considered as a complicated and challenging pathology by surgeons because of the technical operative difficulties and frequent recurrence.

Background: No gold standard exists for grading tricuspid regurgitation (TR) severity. We developed a simple parameter, the right ventricular (RV) early inflow-outflow (RVEIO) index, using the early diastolic filling velocity and RV outflow velocity integrated over the systolic ejection period. We hypothesized that this index would help identify severe TR in clinical practice.
