Infantile Pompe disease (glycogen storage disease type 2) is a fatal disorder caused by deficiency of acid alpha-glucosidase. This deficiency results in glycogen accumulation in the lysosomes of many tissues including cardiac muscle. The disease is characterized by profound hypotonia, poor growth, organomegaly, and cardiomegaly. Severe hypertrophic cardiomyopathy often is ...

Assessment of appropriateness of left ventricular mass (LVM) for a given workload may better stratify hypertensive patients. Inappropriate LVM may reflect the interaction of genetic and neurohumoral factors other than blood pressure playing a significant role in myocardial growth. Primary aldosteronism (PA) represents a clinical model useful in assessing the ...

A 71-year-old man with hepatocellular carcinoma (HCC) presented with intracavitary cardiac involvement detected incidentally on surveillance computed tomography. Tumor with associated thrombus was found to extend from the liver through the inferior vena cava into the right atrium. This intracardiac mass prolapsed intermittently into the right ventricle, causing functional tricuspid ...

BACKGROUND: Left ventricular hypertrophy (LVH) can itself contribute to increased rates of cardiovascular events. We sought to determine the impact of LVH on in-hospital and long-term mortality after coronary artery bypass grafting (CABG). METHODS: Between 1992 and 2003, 4140 consecutive patients underwent CABG. Long-term survival data (mean follow-up 7.0 years) ...

In clinical practice, differential diagnosis among different forms of left ventricular (LV) hypertrophy is not always easy, and hypertrophic cardiomyopathy (HC) can be misdiagnosed. In this study, it was hypothesized that a 3-dimensional echocardiographically derived index of LV regional mass distribution could be useful in differentiating HC from other forms ...

In kidney transplant (KT) recipients, cardiac impact of the persistence of an asymptomatic arteriovenous fistula (AVF) for hemodialysis has not been fully elucidated. Seventy-six patients (mean age: 49 years) without history of diabetes or cardiovascular disease underwent an echocardiography. Thirty-eight had a functioning AVF and were match-paired for age, gender ...

In coronary artery disease (CAD), a potentially reversible factor leading to cardiac death is left ventricular hypertrophy (LVH). While the electrocardiogram (ECG) is a widely available way to diagnose LVH, its sensitivity and specificity has never been assessed in this particular patient group where added ischaemic changes on ECG might ...

We describe an adult patient with a primary left atrial leiomyosarcoma in whom live/real time three-dimensional transthoracic echocardiography showed echolucent areas within the mass consistent with necrosis or hemorrhage surrounded by dense band-like echo densities indicative of fibrosis or collagen giving a "doughnut" like appearance. These findings were consistent with ...

Myocardial edema is a substantial feature of the inflammatory response in human myocarditis. The relation between myocardial edema and myocardial mass in the course of healing myocarditis has not been systematically investigated. We hypothesised that the resolution of myocardial edema as visualised by T2-weighted cardiovascular magnetic resonance (CMR) is associated ...

In hypertension, Left ventricular hypertrophy is initially a useful compensatory process that represents an adaptation to increased ventricular wall stress; however, it is also the first step toward the development of overt clinical disease. For this reason most international guidelines recommend the assessment of cardiac target organ damage in hypertensive ...

Left ventricular hypertrophy (LVH) is a cardinal manifestation of organ damage in patients with arterial hypertension. Identifying LVH is a fundamental step in evaluating hypertensive patients, because clinical and epidemiologic studies have shown this condition has a strong independent adverse prognostic significance. LVH is an integrated marker of cardiovascular risk, ...

Left ventricular hypertrophy (LVH) is primarily or secondarily caused by a cardiovascular or systemic disease. The pattern of LVH is distinctive in hypertrophic or metabolic cardiomyopathy and differs from that seen in LVH caused by hypertension or aortic stenosis.

Left ventricular hypertrophy (LVH), despite its adaptive nature, is associated with an increased risk of cardiovascular morbidity and mortality. Achievement of LVH regression is thus considered a principal therapeutic aim. However, regression of LVH induced by various therapeutic means may exhibit differing patterns, with variable biological implications. Inhibitors of 3-hydroxy-3-methylglutaryl ...
