dobutamine stress echocardiography (dse) has been widely used as a diagnostic and prognostic modality in the management of stress. dse is associated with limited complications and adverse effects on the health of patients. in this case report, we described a 42-year-old female patient with dobutamine-induced coronary artery spasm with history of exertional dyspnea, which had deteriorated recent...

introduction left ventricular (lv) twist is believed to store potential energy and plays an important role in generating diastolic suction. recent advances in echocardiography techniques have allowed quantification of lv twist. the aim of the present study was to compare lv twist and torsion in healthy human subjects determined by velocity vector imaging (vvi) and tissue doppler imaging (tdi) a...

background: embolus is one of the causes of ischemic stroke that can be due to cardiac sources such as valvular heart diseases and atrial fibrillation and atheroma of the aorta. transesophageal echocardiography (tee) is superior in identifying potential cardiac sources of emboli. due to insufficient data on tee findings in ischemic stroke in iran, the present study was done to evaluate tee in d...

background: the most important problem in regular transfusion dependent β-thalassemia major is cardiac dysfunction due to iron deposition in it. the aim of this study was to evaluate correlation between serum ferritin levels and cardiac function in β-thalassemia major in mofid hospital. materials and methods: there were 112 β-thalassemia patients with a mean age of 13.55± 6.12 years, of whom 49...

background: the aim of this study was to echocardiographically assess the effects of eecp (enhanced external counterpulsation therapy) therapy on systolic and diastolic cardiac function. methods: lvef (left ventricular ejection fraction), esv (end-systolic volume), edv (end-diastolic volume), sm (myocardial systolic wave) , ea (myocardial early diastolic wave), vp (propagation velocity), e/ea (...

background: in cases of moderate(2 or 3+ on a scale of 0 to 4+) nonorganic mitral regurgitation (mr) and coronary artery disease, operative strategy continues to be debated between coronary artery bypass grafting alone (cabg) or concomitant valve repair. to clarify the optimal management of these patients, we evaluated the mid-term results of isolated cabg in the study group. methods: from marc...

we report the case of a male patient with community‑acquired quadruple‑valve endocarditis on presumed normal native valves.this patient had originally presented elsewhere with generalized edema and malaise and had been diagnosed with suspicious endocarditis and renal dysfunction, for which he unfortunately received incomplete treatment. transthoracic and transesophageal echocardiographic ex...

conclusions the cardiac grafts at 5 months' post-htx follow-up were characterized by normal lv dimensions and ef. also, rv dysfunction and tricuspid regurgitation were frequent findings, but they were not associated with the clinical signs of congestive heart failure, morbidity, and mortality in the majority of our patients. background in patients with advanced heart failure, significant improv...

patients and methods forty five young female volunteer athletes were included and received different training regimens (endurance-training, strength training and concurrent groups) for a 10 week period as study intervention. standard color doppler echocardiography was performed for assessment of the left ventricular activity. results as a result, 45 athletes ended the study training regimens. m...
