background: echocardiography is the most common test used for the evaluation of aortic regurgitation (ar). however, the role of echocardiography as an available and inexpensive method in the quantification of ar by the left ventricle to right ventricle stroke volume ratio (lv/rv sv ratio) has not been completely investigated. methods: between june 2005 and december 2007, 132 consecutive patient...

introduction although a few patients will survive after penetrating cardiac injuries, some of them may have unnoticeable intracardiac injuries. the combination of aorto-right ventricular fistula with aortic valve injury is rare. case presentation a 19 year-old man referred with an aorto-right ventricular fistula accompanied with aortic regurgitation and delayed tamponade following a stab in the...

adonis aestivalis (summer pheasant-eye) is an annual plant with a crimson flower, distributed in southern europe and asia. the plant has large buttercup-like blossoms and soft, fern-like leaves. it blooms in spring and is often found as a weed in cereal fields. like other adonis spp., the plant produces cardiac glycosides. it is used in remedies for mild weakness of the heart, especially when a...

Abstract Congenitally Corrected Transposition of Great Arteries is a unique condition in which atrio-ventricular discrepancy e ventricular-arteriosus are mutually balanced, so that there the normal oxygenation and distribution blood to tissues, but morphologically right ventricle tricuspid valve have deal with systemic pressures, developing severe ventricular disfunction regurgitation along yea...

Objective(s): The present study was aimed to investigate the influence of thoracic epidural blockade on hypoxia-induced pulmonary hypertension in rats. Materials and Methods: Forty eight Wistar rats were randomly divided into 4 equal groups, named normoxia hypoxia hypoxia/ ropivacaine and hypoxia/saline. Animals were placed in a hypoxia chamber and instrumented with epidural catheters at the t...

Pulmonary hypertension (PH) is an important cause of heart failure in chronic obstructive pulmonary disease (COPD). The pro brain natriuretic peptide N-terminal (NT-proBNP) has been suggested as a noninvasive marker to evaluate ventricular function. However, there is no evidence to support the use of NT-proBNP in monitoring the benefits of vasodilators in COPD induced PH. Thus, we used NT-proBN...

Abstract Introduction: Occurrence of cardiac arrhythmias and myocardial infarction are two main deleterious events that are caused by ischemia-reperfusion (IR) injury in the heart. Cardiac preconditioning represents the most potent method of rescuing heart tissue from undergoing irreversible ischemic damage. The aim of the present study was to evaluate oxytocin (OT) cardioprotective effect...

Background:Cardiac rehabilitation program (CRP) is a useful method of modifying cardiovascular risk factors, improving life expectancy and quality of life in patients with ischemic heart disease (IHD). The present study was conducted to evaluate the effects of cardiac rehabilitation on the pulmonary artery systolic pressure (PASP) and left ventricular end-diastolic pressure (LV...
