patients with valvular heart disease and suffering atrial fibrillation of more than 12 months duration have a low probability of remaining in sinus rhythm after valve surgery alone. we performed intra-operative radiofrequency ablation or cryoablation as an alternative to surgical maze ііі procedure to create linear lesion lines for conversion of this arrhythmia to sinus rhythm. a total of 30 pa...

patients with valvular heart disease suffer from atrial fibrillation for more than 12 months after valve surgery and have a low probability of remaining in sinus rhythm. we performed an intra-operative procedure similar to surgical maze ііі procedure for conversion of this arrhythmia to sinus rhythm. we did this study to evaluate the efficacy of this procedure to restore the sinus rhythm in pat...

it has been well - established that common atrial flutter is due to intraatrial macroreentry and its reentry circuit locates in the right atrium. this reentry circuit has been characterized to involve an area of slow conduction identifiable electrophysiologically at the low posteroseptal right atrium and anatomical narrow isthmus snrrounded by the inferior vena capa, coronary sinus astium and t...

conclusions diagnosis of tachycardia-induced cardiomyopathy in children is important, since appropriate treatment improves the prognosis. every child with recurrent and persistent palpitation with the first episode of congestive heart failure should be evaluated for tachycardia- induced cardiomyopathy. introduction tachycardia-induced cardiomyopathy (tic) is a ventricular dysfunction secondary ...

  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...
