Systemic lupus erythematosus (SLE) is a major cause of nonbacterial thrombotic endocarditis (NBTE) associated with intracardiac sterile vegetations. It is rare for vegetations to present as an atrial tumor. This report describes a 48-year-old female with SLE and antiphospholipid syndrome complicated by recurrent thrombosis on anticoagulation. A large left atrial mass lesion was detected on echocardiography during a work-up for leg burning. Infective endocarditis could not be confirmed, and hence left atrial mass lesion was the most likely diagnosis...

OBJECTIVES: Atherosclerosis is almost absent in intramyocardial coronary arteries, while epicardial coronary arteries may show extensive occlusive disease. Lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) expression has been implicated in atherogenesis. We aimed to investigate differences in arterial wall LOX-1 expression between human epicardial and intramyocardial coronary arteries. METHODS: Epicardial and intramyocardial total artery wall specimens were obtained from 13 male patients (aged 61...

Left ventricular (LV) twist serves as a compensatory mechanism in systolic dysfunction and its degree of reduction may reflect a more advanced stage of disease. AIM: The aim was to investigate twist alterations depending on the degree of functional mitral regurgitation (MR) by speckle-tracking echocardiography. METHODS: Sixty-three patients with symptomatic dilated cardiomyopathy (DCM) were included. Patients were divided according to MR vena contracta width (VCW): group 1 with VCW <7 mm (mild/moderate MR) and group 2 with VCW ≥7 mm (severe MR)...

Contrast-induced encephalopathy (CIE) following coronary angiography (CAG) is a very rare complication. Radiological signs such as cerebral oedema and cortical enhancement are of great importance in the diagnosis. We report a case of probable CIE in a 76-year-old gentleman following a normal diagnostic CAG that involved 120 mL of the iodinated contrast agent iohexol (Omnipaque 300). At 90 min postprocedure he became acutely confused with a normal non-contrast CT of the head. After 9 days of conservative treatment, the patient recovered spontaneously with no neurological deficits...

OBJECTIVE: To determine the prevalence and clinical effects of myocardial bridging (MB) in patients with apical hypertrophic cardiomyopathy (AHCM). METHODS: Angiograms from 212 AHCM patients were reviewed to identify MB. The patients were classified into 2 groups: AHCM with and AHCM without MB. We reviewed patient records on cardiovascular (CV) risk factors, symptoms, CV events, and CV mortality. RESULTS: In all, 60 patients with MB and 100 without MB were included...

Recent epidemiological studies have revealed that the risk factors associated with coronary artery calcification (CAC), including male gender, smoking, hypertension, and elevated serum cholesterol, are similar to the risk factors associated with the development of calcific aortic valve disease (CAVD). The results of the experimental and clinical studies demonstrate that traditional risk factors initiate early atherosclerosis which over time differentiates to form bone in the heart causing clinical CAC and CAVD...

The Valsalva maneuver should be incorporated into the routine of auscultation even when a murmur is absent. Valsalva release affects the second heart sound. It is particularly helpful during detailed, non-perfunctory auscultation in patients with bundle branch block.

OBJECTIVES: We have recently shown that the transient receptor potential vanilloid 2 (TRPV2) channel is exclusively upregulated in rat/murine peri-infarct monocytes/macrophages following an acute myocardial infarction (AMI), and that this overexpression might be detrimental for cardiac recovery. We aimed to characterize the expression levels of TRPV2 in peripheral blood mononuclear cells (PBMCs) of AMI patients relative to individuals with normal coronaries, and to analyze potential associations with inflammatory and cardiac ischemic markers...

OBJECTIVES: The importance of thrombocytopenia (TP) has been discussed previously. However, data are still limited, especially on predictors of TP. We sought to investigate predictors of TP after transcatheter aortic valve replacement (TAVR), in particular, clinically significant TP. METHODS: We reviewed a total of 123 consecutive patients undergoing TAVR in our medical center. They were stratified into 3 groups according to the nadir platelet count post-TAVR: no/mild TP, moderate TP, and severe TP...

BACKGROUND: Multiple studies have quantified the relationship between aortic size and risk of dissection. However, these studies estimated the risk of dissection without accounting for any increase in aortic size from the dissection process itself. OBJECTIVES: This study aims to compare aortic size before and after dissection and to evaluate the change in size consequent to the dissection itself. METHODS: Fifty-five consecutive patients (29 type A; 26 type B) with aortic dissection and incidental imaging studies prior to dissection were identified and compared to a control group of aneurysm patients (n = 205)...

OBJECTIVES: Sacubitril/valsartan was approved recently for the treatment of patients with heart failure and reduced ejection fraction. We present 6 cases of ventricular arrhythmia, that occurred shortly after sacubitril/valsartan initiation, that required drug withdrawal. Other potential triggering factors of electrical storm were ruled out and, from the arrhythmic perspective, all of the patients were stable in the previous year. Our aim is to describe the possible association of sacubitril/valsartan with arrhythmic storm...

BACKGROUND: High residual platelet reactivity (HRPR) during dual antiplatelet therapy (DAPT) may impact clinical outcomes following percutaneous coronary interventions (PCI). However, whether any biomarkers assessed before PCI at DAPT loading may predict delayed maintenance HRPR is not clear. OBJECTIVE: The aim of this study was to determine whether conventional clinical or laboratory indices at loading before stenting may predict HRPR at 6 months of maintenance DAPT...

OBJECTIVE: The aim of this study is to investigate the correlation between calcineurin (CaN) and hypertension with left ventricular hypertrophy (HLVH) and to evaluate its potential clinical significance. DESIGN: The study involved 160 patients diagnosed with hypertension and 42 controls. Based on the exclusion criteria, 42 were not eligible for this study. The remaining 118 hypertensive patients were categorized into 2 subgroups based on left ventricular mass index and relative ventricular wall thickness: a normal model subgroup with hypertension (HNM) and an HLVH subgroup...

OBJECTIVES: The aim of this study was to evaluate the association of miR-126 with risk and severity of coronary artery disease (CAD) as well as its correlation with inflammatory cytokines and endothelial related proteins. METHODS: In total, 215 patients suspected of CAD who underwent coronary angiography were enrolled in this case control study and were divided into a CAD group (n = 119) and control group (n = 96). miR-126 relative expression was assessed by real-time polymerase chain reaction...

OBJECTIVES: We sought to clarify clinical features and outcomes related to calcified nodules (CN) compared with plaque rupture (PR) and plaque erosion (PE) detected by optical coherence tomography (OCT) at the culprit lesions in patients with acute coronary syndrome (ACS). METHODS: Based on OCT findings for culprit lesion plaque morphologies, ACS patients with analyzable OCT images (n = 362) were classified as CN, PR, PE, and other. RESULTS: The prevalence of CN, PR, and PE was 6% (n = 21), 45% (n = 163), and 41% (n = 149), respectively...
