background: brain type natriuretic peptide (bnp) is a cardiac hormone that is secreted mainly by the ventricles in response to volume expansion and pressure load. it can predict post-operative complications after heart surgery in adults. we sought to investigate the prognostic value of bnp in children after heart surgery. methods: we measured the bnp serum levels in 96 children with congenital ...

background: extubation is associated with the risk of complications such as accumulated secretion above the endotracheal tube cuff, eventual atelectasia following a reduction in pulmonary volumes because of a lack of physiological positive end expiratory pressure, and intra-tracheal suction. in order to reduce these complications, and, based on basic physiological principles, a new practical ex...

background: postoperative cognitive dysfunction (pocd) has been an important complication of cardiac surgery over the years. neurocognitive dysfunction can affect quality of life and lead to social, functional, emotional, and financial problems in the patient’s life. to reduce pocd, we sought to identify the association between cognitive dysfunction and perioperative factors in patients undergo...

acute left atrial thrombosis at the site of the resection of the primary cribriform septum is an exceedingly rare and important complication after atrial septal defect (asd) closure with a pericardial or synthetic patch. this case report presents a mobile thrombus noted on the left atrium at the raw surface site of a resected cribriform primary septum that was not caught in the suture line with...

Transcatheter aortic valve replacement (TAVR) is a novel therapeutic intervention for the replacement of severely stenotic aortic valves in high-risk patients for standard surgical procedures. Since the initial PARTNER trial results, use of TAVR has been on the rise each year. New delivery methods and different valves have been developed and modified in order to promote the minimally invasive p...

patients and methods previously recorded data of 231 patients who underwent surgical closure of vsd between january 2009 and january 2012 at the rajaie cardiovascular medical and research center were retrospectively reviewed. vsd surgical repair was performed using continues suturing technique in group a patients (n = 163, 70.6%) and interrupted suturing technique in group b patients (n = 68, 2...

a 54-year-old man referred to our center with barlow’s disease and severe mitral regurgitation. he had atrial fibrillation (af) rhythm, with a mildly enlarged left atrium (la). transesophageal echocardiography (tee) showed no clot in the la and la appendage; there was only mild spontaneous echo contrast in the la appendage. the patient underwent mitral valve repair and the maze operation, durin...

autogenous tooth transplantation (att) is a simple and reasonable choice for replacing the missing teeth when a proper donor tooth is available. this report presents a case of successful att of a maxillary right third molar for replacement of mandibular right second molar with a concomitant endodontic-periodontal disease. the mandibular second molar was believed to be hopeless due to a severe d...
