Atrial Septal Defect in a Newborn Holstein Calf: OAJBS Publishers
Atrial Septal Defect in a Newborn Holstein Calf by Akbar Nikkhah* in Open Access Journal of Biomedical Science (OAJBS) We aimed to present a case of atrial septal defect (ASD) in a new-born Holstein calf in a commercial dairy farm in Tehran, Iran. Despite the incidence of some congenital cardiac disorders such as ventricular septal defect (VSD) in young calves, detection of ASD in Holstein calves has been rarely reported with no distinct picture of the area involved. In the current report, ASD is pictured noticeably which would be an appropriate example for diagnosing it in other cases. Apparently, issues related to cardiac system occur more frequently than expected, however, they are not diagnosed precisely on farm mainly because of inadequate knowledge of such disorders. Young dairy calves are often diagnosed with respiratory distress or fever with weakness and hyperpnea. Severe hyperpnea may be associated with heart defects which can be confused with respiratory diseases and fever...
