Aim:The aim of this study was to analyze the sensitivity and specificity of cardiac gated SPECT imaging and to assess the diagnostic potential of quantitative perfusion and the left ventricular function parameters to identify high-risk patients with multivessel coronary artery disease (CAD). Methods:582 patients (412 men, mean age 62 ± 10 years, 164 after previous myocardial infarction, 125 after revascula-rization) underwent a stress gated SPECT study followed by coronary angiography. A summed stress score (SSS), post-stress and rest left ventricular ejection fraction (LVEF) and transient ischemic dilatation ratio...

Background:In an animal study, hemodynamic overload of 8 mmHg increased the amount of released B-type natriuretic peptide (BNP) within 4 hours. Aim:To determine whether the worsening of hemodynamic parameters by 2.0 to 4.8 mmHg (pulmonary artery wedged pressure) due to a change from chronic biventricular pacing (BiVP) to isolated right ventricular pacing (RVP) would increase the plasma levels of BNP in the human body. Method:A total of 18 patients with chronically optimized heart failure treatment including BiVP (16.7 ± 13.8 months) were randomized at a 1 : 1 ratio to a 4-hour period of the type of cardiac...

We present the case report of a 36-year-old man with a 2-year history of cardioverter/defibrillator implantation due to right ventricular dysplasia. He presented to a cardiology outpatient clinic because of dyspnea worsening.He was diagnosed to have right-heart failure. On a CT scan, we found a high-flow AV malformation shunt which was the cause of the heart failure. There was also right ventricular overload.After angiographic and echocardiographic investigations, tricuspid annuloplasty and right nephrectomy were performed with a very good outcome.

Ventricular assist devices in the management of terminal heart failure

Cor Vasa 2008, 50(5):207-214 | DOI: 10.33678/cor.2008.069  

Ventricular assist devices are currently one of the most dynamically evolving fields of modern cardiology and cardiac surgery. In heart transplantation, they have become a routine and effective method, which allows bridging the critically failing patient to the time until a suitable donor heart becomes available. Technical innovation has expanded their potential utility to new areas of indication; there has also been a substantial shift in terms of their service life and user friendliness to the patient including the possibility of outpatient therapy. The article presents, in a broader context, the classification of systems with attention to their...

Diagnosing chronic heart failure

Chronic heart failure (CHF) is one of the few cardiovascular pathological conditions whose prevalence and incidence in the population is on the rise. To explain, the incidence of CHF increases markedly with age, which is increasing quite rapidly in developed nations. In addition, management of acute cardiovascular disease is increasingly successful, with people no longer dying of it, but frequently surviving with myocardial injury, thus becoming candidates for developing CHF. Some experts even refer to an epidemiology of the 21st century.Heart failure may develop secondary to either systolic or diastolic left ventricular dysfunction. The diagnosis...
