Dilated cardiomyopathy (DCM) is a multifactorial heart disease in which there is enlargement and systolic dysfunction of one or both ventricles. The exhaustion of compensatory mechanisms leads to symptoms of congestive heart failure, which is a significant problem in contemporary cardiology. DCM is still diagnosed using clinical assessment; echocardiography is necessary, and in some clinical si...

heart failure is a clinical syndrome characterized by the inability of the heart to provide nutrient supply to tissues. in 75% of cases, the underlying pathology causing heart failure in patients with cardiac death is coronary heart disease. a rabbit model of heart failure with coronary ligation was produced to mimic coronary heart disease in humans. after producing the model, two arteries and ...

  Cor triatriatum is an acyanotic congenital heart disease. We present a rare case of cor triatriatum sinistrum in a 6-month-old female infant who was presented with cyanosis and failure to thrive. The 2D transthoracic echocardiography and the Doppler color flow imaging showed a proximal venous chamber communicating to the distal left atrium  through restrictive opening to the low-pressure, dis...

A clinical case of successful surgical treatment in a patient with severe New York Heart Association (NYHA) functional class IIIIV heart failure, critical aortic stenosis, and extremely low left ventricular (LV) ejection fraction (EF) (16%) is presented. Aortic valve leaflet replacement was performed according to the Ozaki technique. The postoperative course uneventful discharged from hospital ...

A total of 14 cases of infective endocarditis (IE) in children aged 6 months to 10 years were seen from December 1987 to December 1992 at the pediatric unit of Ayatollah Taleghani Medical Center. The majority of patients (12 of 14) were between 5 and 10 years of age. Acyanotic congenital heart disease was known to preexist in 78.6% and rheumatic valvular heart disease in 21.4% of cases. Or...

700 the echocardiography performed during and after treatment, LVEF was still normal, but longitudinal function of both ventricles was increased: LV-GLS was –17.4% and RV-FWS was –24.3%. The biopsies performed weekly during the first month after heart transplantation revealed no additional signs of significant rejection (1a, 2, 1a ISHLT grade). Echocardiography performed in the 2nd month after ...

The idea that diastolic dysfunction may give rise to symptoms of cardiac disease independent of any impairment of systolic function is not new, and was appreciated centuries ago.2 Traditional definitions of heart failure have focused on abnormalities of systolic or pump function ofthe heart, emphasizing the failure of cardiac output to meet the metabolic requirements of the body at peak workloa...

background chronic heart failure (chf) is associated with unpredictably increased prevalence of hospital admissions. self-care is one of the most important aspects of management for patients with chf. self-care adequacy has led to increased satisfaction, independence in daily activities, reduced stress, and morbidity. objectives we aimed to assess the relationship between self-care behavior and...

n-terminal pro β-type natriuretic peptide (nt-probnp) is a valuable marker for monitoring the response to treatment in patients with heart failure. based on the clinically observed improvement of heart failure symptoms early after cardiac resynchronization therapy (crt), we sought to investigate whether crt induce any significant reduction in the plasma level of nt-probnp in three days after im...
