Study of the normal heart size in Northwest part of Iranian population: a cadaveric study [PDF]
Journal of Cardiovascular and Thoracic Research, 2016 Introduction: The heart is in a muscular organ in the middle mediastinum. According to our knowledge, there is no standard data about the anthropologic parameters of normal Iranian hearts. Hence, the aim of the present study was to investigate the normal

Biological niches within human calcified aortic valves. Towards understanding of the pathological biomineralization process [PDF]
, 2015 Despite recent advances, mineralization site, its microarchitecture, and composition in calcific heart valve remain poorly understood. A multiscale investigation, using scanning electron microscopy (SEM), transmission electron microscopy (TEM), and ...

On-pump fibrillating heart mitral valve replacement with the SAPIEN XT transcatheter heart valve [PDF]
European Journal of Cardio-Thoracic Surgery, 2013 In some high-risk patients, standard mitral valve replacement can represent a challenging procedure, requiring a risky extensive decalcification of the annulus. In particular, high-risk redo patients and patients with a previously implanted transcatheter aortic valve, who develop calcific mitral disease, would benefit from the development of new ...

Diagnosis of mitral insufficiency using impedance cardiography technique ICG
Journal of Electrical Bioimpedance, 2016 Impedance cardiography (ICG) is a non-invasive tool for assessing the hemodynamic parameters. It has been used for diagnosing several cardiovascular diseases, such as heart failure, cardio-myopathy, and valvular diseases. Particularly, the valvular heart

Twisted atrioventricular connections in double inlet right ventricle: evaluation by magnetic resonance imaging [PDF]
, 2008 Twisted atrioventricular connections occur almost exclusively in the hearts with biventricular atrioventricular connections. Only one example of double inlet left ventricle has been illustrated in which the axes of the two atrioventricular valves crossed
