background: echocardiographic evaluations of the longitudinal axis of the left ventricular (lv) function have been used in the diagnosis and assessment of heart failure with normal ejection fraction (hfnef). the evaluation of the global and segmental peak systolic longitudinal strains (pslss) by two-dimensional speckle tracking echocardiography (ste) may correlate with conventional echocardiogr...

bifid cardiac apex is a rare anomaly of human hearts. we report of the case of a 34-year-old man with a previous history of ventricular septal defect (vsd) and subvalvular pulmonary stenosis. he had undergone pulmonary commissurotomy and vsd closure 22 years before he was referred to our center for evaluation of progressive dyspnea. transthoracic echocardiography revealed atrial septal defect (...

background: it is not clear whether the latest activation sites in the left ventricle (lv) are matched with infracted regions in patients with ischemic cardiomyopathy (icm). we aimed to investigate whether the latest activation sites in the lv are in agreement with the region of akinesia in patients with icm.   methods: data were analyzed in 106 patients (age = 60.5 ± 12.1 y, male = 88.7%) with...

background : the signal-averaged electrocardiography is a noninvasive method to evaluate the presence of the potentials generated by tissues activated later than their usual timing in the cardiac cycle. the purpose of this study was to demonstrate the correlation between the filtered qrs duration obtained via the signal-averaged electrocardiography and left ventricular dimensions and volumes an...

background: venoarterial extracorporeal membrane oxygenation (ecmo) provides systemic arterial support without directly unloading the left heart, which causes an elevated left ventricular (lv) pressure. the aim of the present study was to investigate the adjunctive application of the impella device for lv unloading in patients during ecmo. methods: this retrospective cohort study included patie...

abstract hypoplastic right ventricular is a rare congenital heart disease. a few cases have been reported. we presented a case with hypoplastic right ventricular and multiple associated anomaly (ventricular septal defect, atrial septal defect and pulmonary stenosis) in whom the main concern was whether biventricular repair or fontan type surgery would be the optimal management in this patient. ...

background: cardiac rehabilitation has been recognized as one of the most effective strategies for managing cardiovascular indices as well as controlling the cardiovascular risk profile, in particular after coronary artery bypass graft surgery (cabg). however, the effect of this program on right ventricular function following cabg is unclear. the aim of this study was to evaluate the impact of ...

arrhythmogenic right ventricular dysplasia/cardiomyopathy (arvd/c) is a congenital cardiac disease with myocardial involvement, most probably right ventricular (rv) dysfunction, accounting for 20% of sudden cardiac deaths. characterized by the fibro-fatty infiltration of the rv free wall, arvd/c presents in adolescents with ventricular arrhythmias and heart failure symptoms and as biventricular...

background: conventional doppler measurements, including mitral inflow and pulmonary venous flow, are used to estimate left ventricular end diastolic pressure (lvedp). however, these parameters have limitations in predicting lvedp among patients with mitral regurgitation. this study sought to establish whether the correlation between measurements derived from tissue doppler echocardiography and...

background : sleep apnea is accompanied by some cardiovascular complications. it has even been hypothesized that sleep apnea, itself, can induce some of these complications. given such controversies, we assessed the left ventricular mass index (lvmi) and systolic pulmonary artery pressure in patients with sleep apnea. methods: through convenience sampling, 56 patients with the obstructive sleep...
