: We aimed to evaluate the correlation and agreement between the Systemic Coronary Risk Estimation 2 (SCORE2) and Predicting Risk of CVD EVENTs (PREVENT) 10-year ASCVD risk scores by incorporating computed tomographic (CT) data to assess differences between the scoring systems. : The PREVENT risk score was calculated for 171 patients, while the SCORE2 and SCORE2 Older Persons (OP) risk scores were calculated for 113 patients. Coronary artery calcium (CAC) scores were calculated, and the grading of coronary artery disease (CAD) was assessed according to these scores.

Aims: Right ventricular (RV) failure is one of the leading causes of death in patients with pulmonary hypertension (PH). Conventional echocardiographic parameters are not included in risk stratification and follow-up for prognostic assessment due to PH's diverse nature and the RV's complex geometry. RV outflow tract velocity time integral (RVOT VTI) is a simple, non-invasive estimate of pulmonary flow and an echocardiographic surrogate of RV stroke volume.

Introduction: We aimed to determine the relationship between the dilatation of the heart chambers and the change in peritoneal membrane solute transfer characteristics (PMTC) in long-term peritoneal dialysis (PD) patients.

Methods: This is a retrospective, single-center study including the follow-up of maintenance PD patients. According to the changes in PMTC from baseline to the last visit, patients were divided into three groups; stable (n = 11), increased (n = 41), and decreased transporters (n = 35).

Spontaneous coronary artery dissection (SCAD) is an atypical cause of myocardial infarction, predominantly seen in women. Among various predisposing factors, genetic vasculopathies such as connective tissue diseases significantly contribute to SCAD. This report discusses a 36-year-old male diagnosed with vascular type Ehlers-Danlos syndrome following an anterior myocardial infarction and explores relevant literature.

Objective: Right ventricular (RV) dilatation and dysfunction are usually present in heart transplant (HTx) patients and worsened with residual pulmonary hypertension (PH). We aimed to determine the ability of different echocardiographic modalities to evaluate RV function in comparison with cardiac magnetic resonance (CMR) and their relations with pulmonary hemodynamics in HTx patients.

Methods: A total of 62 data sets [echocardiographic, hemodynamic, and CMR] were acquired from 35 HTx patients.

Objective: The ventriculoarterial uncoupling has been linked with unfavorable results as measured noninvasively by tricuspid annular plane systolic excursion divided by systolic pulmonary artery pressure (TAPSE/sPAP). However, its prognostic importance in chronic thromboembolic pulmonary hypertension (CTEPH) is limited. Thus, we determine the effect of the TAPSE/sPAP ratio on outcomes and predictors of all-cause mortality in these patients.

Approximately one-third of bone morphogenic protein receptor-2 (BMPR2) mutation carriers develop pulmonary arterial hypertension (PAH), which indicates that additional risk factors are needed for the manifestation of the disease. It is questionable whether pregnancy is a risk factor for PAH development in these patients. We represent a 30-year-old woman with a heterozygous BMPR2 mutation who was diagnosed with PAH during the postpartum period and reviewed the literature in this report.

Aims: Right ventricular (RV) dysfunction is an important cause of graft failure after heart transplantation (HTx). We sought to investigate relative merits of echocardiographic tools and cardiac magnetic resonance (CMR) with T1 mapping for the assessment of functional adaptation and remodelling of the RV in HTx recipients.

Methods And Results: Sixty-one complete data set of echocardiography, CMR, right heart catheterization, and biopsy were obtained.

Aims: Anticoagulation is not justified unless atrial fibrillation (AF) is detected in cryptogenic stroke (CS) patients. We sought to explore whether left atrial (LA) remodelling is associated with embolic stroke of undetermined source (ESUS).

Methods And Results: In this prospective study, we evaluated consecutively 186 patients in sinus rhythm who presented with an acute ischaemic stroke (embolic and non-embolic) and sex- and age-matched controls.

Traditional parameters have limited value to estimate left ventricular filling pressure (LVFP) in orthotropic heart transplant (OHT) recipients. We hypothesized that global longitudinal strain (GLS), diastolic, and systolic strain rate (SR) would be depressed in OHT recipients with elevated LVFP and could overcome the limitations of traditional parameters. We studied consecutively OHT patients at the time of endomyocardial biopsies and retrospectively pretransplantation studies conforming to the same protocol.

Background: Obstructive sleep apnea syndrome (OSAS) leads to right ventricular (RV) dysfunction and pulmonary hypertension (PH) in the later stages. Early determination of these conditions is very important.

Objectives: We aimed to evaluate the correlations of pulmonary artery distensibility, right pulmonary artery fractional shortening (RPA-FS), and pulmonary artery stiffness (PAS) with PH among newly diagnosed OSAS patients.

Background: A possible relationship between an obstructive prosthesis and suboptimal hemodynamic recovery, as reflected by unsatisfactory regression in systolic pulmonary artery pressure (sPAP) and functional tricuspid regurgitation (FTR) following mitral valve replacement (MVR), was investigated. A delineating effective orifice area index (EOAI) value was sought in order to define a patient-prosthesis mismatch.

Methods: A total of 128 patients undergoing isolated mechanical MVR were followed up for a mean of 46 ± 9 months.

Background: Leukoaraiosis (LA) is closely associated with cognitive deficits. The association between LA and cognitive disorders, such as mild cognitive impairment (MCI) and dementia, after initial stroke has not been systematically studied. In this study, we sought to identify whether LA contributes to the occurrence of certain type of cognitive disorders after initial stroke.

Background: Despite the advances in medical and interventional treatment modalities, some patients develop epicardial coronary artery reperfusion but not myocardial reperfusion after primary percutaneous coronary intervention (PCI), known as no-reflow. The goal of this study was to evaluate the safety and efficacy of intracoronary epinephrine in reversing refractory no-reflow during primary PCI.

Methods: A total of 248 consecutive STEMI patients who had undergone primary PCI were retrospectively evaluated.

Glycogen storage disease type IV (GSD IV) is an autosomal recessive disorder due to the deficiency of α 1,4-glucan branching enzyme, resulting in an accumulation of amylopectin-like polysaccharide in various systems. We describe two cases, a 23-year-old girl with dilated cardiomyopathy who presented with progressive dyspnea and fatigue and a 28-year-old girl with hypertrophic cardiomyopathy who was asymptomatic, secondary to the accumulation of amylopectin-like fibrillar glycogen, in heart. In both patients, the diagnosis was confirmed by enzyme assessment.

A 74-year-old male patient presented with complaints of fatigue, fever, and worsening health status. He had a 34-month history of cardioverter-defibrillator (ICD) implantation due to ischemic cardiomyopathy. Transthoracic and transesophageal echocardiography showed a mobile mass, 24 x 11 mm in size, consistent with a vegetation attached to the right ventricular ICD lead.

Objectives: We aimed to analyze acute clinical, echocardiographic, and hemodynamic results and long-term event-free survival of percutaneous mitral balloon valvuloplasty (PMBV) in the treatment of hemodynamically significant mitral stenosis (MS).

Study Design: We retrospectively reviewed 577 patients (454 females, 123 males; mean age 38±11 years) who underwent PMBV for moderate or severe MS. Acute procedural success was defined as the achievement of mitral valve area (MVA) >1.
