The amount of epicardial adipose tissue (EAT) around the heart has been identified as an independent predictor of coronary artery disease (CAD), potentially through local release of inflammatory cytokines. Ethnic differences have been observed, but no studies have investigated this relationship in the Mexican population. The objective of the present ...

Hypertensive heart disease (HHD) and hypertrophic cardiomyopathy (HCM) are the most frequently encountered entities presenting left ventricular hypertrophy in routine echocardiographic examination, and their differentiation is sometimes difficult. Abnormalities in right ventricular (RV) myocardium have been reported frequently in patients with HCM more than in those with HHD. We therefore ...

Major anterior circulation ischemic strokes caused by occlusion of the distal internal carotid artery or proximal middle cerebral artery or both account for about one third of ischemic strokes with mostly poor outcomes. These strokes are treatable by intravenous tissue-type plasminogen activator and endovascular methods. However, dynamics of infarct growth ...

Left ventricular ejection fraction (LVEF) is the single most important predictor of prognosis in patients with coronary artery disease (CAD) and left ventricular (LV) dysfunction. Equilibrium radionuclide ventriculography (ERNV) is considered the most reliable technique for assessing LVEF. Most of these patients undergo two dimensional (2D) echocardiography and myocardial viability ...

Obtaining a right-chest electrocardiogram is essential for diagnosing concomitant right ventricular infarction in patients with inferior wall acute myocardial infarctions. A software program to synthesize right-chest electrocardiographic waveforms from 12-lead electrocardiographic waveforms is available in Japan. However, its reliability has not been fully investigated. Accordingly, the aim of this study ...

Segmental testicular infarction is a rare cause of acute scrotal pain. The appearances on grey-scale sonography are often indistinguishable from that of a testicular tumour, resulting in unnecessary orchiectomy. We report a case of acute bilateral testicular infarction, of unknown etiology, which was conservatively managed to resolution following a confident ...

Heart malformations are common congenital defects in humans. Many congenital heart defects involve anomalies in cardiac septation or valve development, and understanding the developmental mechanisms that underlie the formation of cardiac septal and valvular tissues thus has important implications for the diagnosis, prevention and treatment of congenital heart disease. The ...

Left ventricular diverticula are congenital anomalies and are not as rare as previously thought. In adults, cardiac diverticula are generally accidental findings during imaging modalities, but concomitant disorders might frequently coexist. The pathophysiology, management, prognosis, and natural history of cardiac diverticula remain poorly understood and controversial. Definite diagnosis is often ...

Abstract  Ventricular septal rupture (VSR) complicates acute myocardial infarction (AMI) in less than 0.2% of cases and is usually surgically managed by endocardial patch repair with infarct exclusion. Although successful in 80% of cases, failure of patch repair (often because of patch dehiscence) results in attempts at percutaneous closure as ...

ABSTRACT:: Electrocardiography (ECG) is a useful tool for detecting ischemic heart disease. However, it has been pointed out that those ECG abnormalities resembling myocardial ischemia may be induced by extracardiac factors. We describe a 44-year-old man in whom a colonic tube was used for esophageal reconstruction via the anterior mediastinum ...

During embryogenesis, the heart is one of the first organs to develop. Its formation requires a complex combination of migration of cardiac precursors to the ventral midline coupled with the fusion of these cardiogenic fields and subsequent cellular reorganization to form a linear heart tube. A finely controlled choreography of ...

Atrioventricular septal defects comprise a disease spectrum characterized by deficient atrioventricular septation, with several common features seen in all affected hearts and variability in atrioventricular valve morphology and interatrial and interventricular communications. Atrioventricular septal defects are among the more common defects encountered by pediatric cardiologists and echocardiographers. Despite advances in ...

Intra-Atrial Conduction Block. A 42-year-old woman with a history of cardiomyopathy and multiple ablation procedures for atrial tachycardia developed intra-atrial conduction block that mimicked atrioventricular (AV) nodal block during radiofrequency ablation at the cavotricuspid isthmus. She was treated with atrial pacing (from the coronary sinus), which overcame intra-atrial conduction block ...

Ventricular septal defect, a potentially deadly complication of transmural myocardial infarction, is often accompanied by ischaemic mitral regurgitation. It has been recognized that the presence and persistence of the latter negatively affect survival rates in patients after myocardial infarction. We present a simple endoventricular edge-to-edge technique of mitral repair using ...

Unroofed coronary sinus (coronary sinus-type atrial septal defect) is a rare congenital anomaly resulting from imperfect development of left atrio-venous fold. This malformation is not considered suitable for percutaneous treatment due to complex anatomy and risk of coronary sinus obstruction. This paper reports on the first successful treatment of partially ...

Extracorporeal membrane oxygenation (ECMO) is often used to provide cardiopulmonary support for infants experiencing severe levels of cardiac or respiratory failure. In patients with two ventricles and no intra-atrial communication, ECMO is often complicated by limited venous return to the circuit and marked left atrial hypertension. This condition may be ...

Cardiac cushion formation is crucial for both valvular and septal development. Disruption in this process can lead to valvular and septal malformations, which constitute the largest part of congenital heart defects. One of the signaling pathways that is important for cushion formation is the TGFβ superfamily. The involvement of TGFβ ...
