This study was designed to investigate the potential role of radionuclide angiographic phase imaging in defining ventricular pacing sites. Twenty patients were paced from multiple right ventricular and left ventricular sites. Ten patients had both normal wall motion and normal electrocardiograms (ECGs), while 10 patients had segmental wall motion abnormalities and/or bundle branch block. Both c...

A 58-year-old man was admitted to our tertiary care hospital because of new-onset heart failure during the last 4 weeks and sustained ventricular tachycardia (Figure 1). Before admittance to our hospital, coronary artery disease was ruled out by coronary angiography at another hospital. At that time, left ventricular angiography showed slightly reduced left ventricular function and inferior hyp...

ebstein anomaly is characterized by apical displacement of the septal and posterior tricuspid valve leaflets, leading to atrialization of the right ventricle and could be diagnosed in a routine transthoracic echocardiography exam. we reported a young man with right sided heart failure symptoms who was found to have biventricular failure with suspected apical displacement of septal leaflet of tr...

Methods Patients were referred for cardiovascular magnetic resonance imaging prior to LVAD placement. We assessed the association of mortality to pre-LVAD right ventricular end systolic volume index (RVESVI), right ventricular end diastolic volume index (RVEDVI), left ventricular ejection fraction (LVEF) by CMR. Right ventricular stroke work index (RVSWI) was determined by preLVAD right heart c...

right ventricular failure due to right coronary artery disease, right ventricular hypertrophy, stunning, abnormal septal motion, myocardial infarction, or non-homogeneous distribution of cardioplegia is an uncommon but serious complication of open heart surgery. we report a patient with severe right ventricular hypertrophy secondary to severe mitral valve stenosis and another patient with detac...

backgroundasthma is the most chronic inflammatory disorder of the airways in children and asthmatic patients can experience cardiac dysfunction, pulmonary hypertension and finally cor pulmonale later in life. we aimed to investigate right ventricular (rv) functions in asthmatic children by conventional and tissue doppler echocardiography (tde).materials and methods pulmonary function tests, con...
