STUDY OBJECTIVE Assisted ventilation may adversely affect out-of-hospital cardiac arrest outcomes. Passive ventilation offers an alternate method of oxygen delivery for these patients. We compare the adjusted neurologically intact survival of out-of-hospital cardiac arrest patients receiving initial passive ventilation with those receiving initial bag-valve-mask ventilation. METHODS The autho...

Thymosin beta4 (TB4) has multiple functions in cellular response in processes as diverse as embryonic organ development and the pathogeneses of disease, especially those associated with cardiac coronary vessels. However, the specific roles played by TB4 during heart valve development in vertebrates are largely unknown. Here, we identified a novel function of TB4 in endothelialmesenchymal transf...

Background and aims: Ankylosing spondylitis (AS) is an idiopathic chronic inflammatory disease mainly involves sacroiliac and axial joints; but it may also have extra-articular involvement. Accordingly, this study was designed to determine the frequency of cardiac involvement among patients with ankylosing spondylitis. Methods: This study was performed as a descriptive-analytical cross-se...

surgery and to enhance our understanding of the pathophysiology of mitral stenosis. Although surgery produced a significant increase in calculated mitral valve area, the degree of improvement varied markedly. The younger patients had the greater increase in mitral valve area. The change in cardiac index and pulmonary vascular resistance correlated well with the change in mitral valve area. Only...

Primary tumors of the heart are rare, and among them, cardiac myxoma is the most prevalent primary cardiac neoplasm in adult patients. Astrocytoma is the most common glioma and can occur in most parts of the brain and occasionally in the spinal cord. There is a little knowledge about coexistence of cardiac myxoma and astrocytoma in the literature. Cardiac myxoma associated with intracranial tum...

Patients with liver cirrhosis are prone to the development of severe complications associated with high mortality rates after major surgery, especially cardiac surgery using cardiopulmonary bypass (CPB). We report the case of a 65-year-old man with acute infective endocarditis and aortic valve perforation, complicated by non-cardiac liver cirrhosis (Child-Pugh class B). After careful preoperati...

A three year old girl with severe congenital mitral stenosis was successfully treated by percutaneous balloon dilatation of the mitral valve. Cardiac catheterisation and cross sectional and Doppler echocardiography indicated that the orifice of the mitral valve had doubled in area. A small atrial septal defect was found at follow up cardiac catheterisation and angiography. Balloon dilatation of...

INTRODUCTION Heart valve injury following blunt chest trauma of car accidents is increasing. Although aortic valve involvement is rare, however, in survivors of blunt cardiac trauma it is the most commonly involved valve and the most frequent valve lesion is isolated injury of the noncoronary cusp of aortic valve. CASE PRESENTATION A 31-year-old man with a history of car accident (five months...

A 60-year-old, asymptomatic woman with no relevant cardiac history underwent 2-dimensional transthoracic echocardiography as part of a study protocol. The echocardiogram (Fig. 1) indicated the presence of a large mobile mass on the anterior leaflet of the tricuspid valve without notable regurgitation or obstruction. Electrocardiographic, chest radiographic, and laboratory values were within nor...
