Percutaneous closure of atrial septal defects in adults has emerged as an alternative to surgery. We report a sequela of such closure in a 16-year-old boy: embolization of the atrial septal defect occluder into the main pulmonary artery when the patient experienced an episode of intense coughing immediately after device deployment. We removed the device(More)
OBJECTIVE Levosimendan has anti-ischaemic effects, improves myocardial contractility and increases systemic, pulmonary and coronary vasodilatation. These properties suggest potential advantages in high-risk cardiac valve surgery patients where cardioprotection would be valuable. The present study investigated the peri-operative haemodynamic effects of(More)
OBJECTIVE The aim of this study is to assess mid-term outcomes of reduction aortoplasty and wrapping technique which is an alternative method to replacement of the aorta in ascending aortic aneurysms. We aimed to show the efficacy of this technique especially when used for patients with increased perioperative mortality or morbidity due to their concomitant(More)
OBJECTIVE The main purpose of this study was to assess the patency of left internal thoracic artery (LITA) graft by using color Doppler ultrasonography (CDUSG) and furthermore to determine the sensitivity and specificity of CDUSG for patency by using coronary angiography as the reference standard. METHODS This study is an observational cohort study on(More)
Aortic arch aneurysm, pseudocoarctation, and coronary artery stenosis are extremely rare in Behçet's syndrome. We present the case of a 25-year-old man with Behçet's syndrome who underwent coronary artery bypass grafting for severe stenosis in the proximal left anterior descending coronary artery and concomitant surgical correction of a saccular aneurysm(More)
Arteriovenous fistula is defined as an abnormal communication between the arterial and venous systems. The complexity of congenital arteriovenous malformations makes treatment challenging. We present the case of a 23-year-old woman who had a complex congenital arteriovenous malformation in her left leg and a history of 2 unsuccessful coil-embolization(More)
OBJECTIVE : Thrombosis of mechanical heart valve prosthesis is a rare fatal complication after heart valve replacement. Although surgical intervention is the suggested treatment in many series, fibrinolytic treatment offers a good alternative. We describe eight cases with mechanical aortic valve thrombosis and compare their results after fibrinolytic(More)
BACKGROUND Surgical treatment of a ruptured abdominal aorta aneurysm (RAAA) continues to present a significant challenge to surgeons. There are some patient factors such as age and gender that cannot be changed, and comorbid conditions can be optimized but not eliminated. The purpose of this study was to identify the risk factors affecting high mortality(More)
