This study was conducted to assess the incidence of abnormalities of ventricular depolarization (late potentials) in children with sinus rhythm after open heart surgery and their relation to spontaneous ventricular tachycardia. Open heart surgery, particularly operations involving ventriculotomy, may predispose patients to the development of ventricular tachycardia (VT) or ventricular fibri...

Background: Hypothermia is usually used during cardiac surgery to further protect against cardiac and cerebral ischemia. However, cognitive impairment could be a common complication after open heart surgery. This study aims to determine the effect of rewarming on the cognitive status of patients after open heart surgery.  Methods: The present study was conducted as a double-blind, randomized c...

Heart failure is associated with high morbidity and mortality and is proving to be an economic burden in developing countries. A number of therapeutic agents are presently employed in heart failure; but they are not sufficient to control symptoms of heart failure. Moreover, the prevalence of chronic heart failure is progressively increasing and thus there is a continuing need to develop effecti...

right atrial dilation due to left heart disease is a common complication among adults. the present review aimed to describe a case of massively dilated right atrium in a female patient presenting with valvular heart disease and no atrial fibrillation. the results of chest x-ray revealed a large opacity filling the lower right hemithorax, falsely interpreted as a mediastinal mass. during the tra...

Background: Respiratory function in patients undergoing open heart surgery is disrupted after surgery.  Patient education on managing complications can reduce occurrence or severity of them. A variety of educational tools has been introduced, but there are controversies about the most appropriate tools. Aim: Determine the effect of instructional videos on respiratory function of the patients af...

A technique is described to control recurrent or sustained supraventricular tachycardia associated with rapid ventricular rates following open heart surgery. The technique utilizes a pair of temporarily implanted atrial epicardial wire electrodes to pace the heart. In one group of patients with recurrent atrial flutter and 2:1 A-V conduction, continuous rapid atrial pacing at 450 beats/min prod...
