dissection of the sinus of valsalva is a rare and life-threatening event. it often occurs during percutaneous coronary intervention in the right coronary artery (rca). dissection flap usually involves the rca and the right sinus of valsalva. here we report two extremely rare cases of spontaneous dissection limited to the non-coronary sinus of valsalva, causing severe aortic valve regurgitation:...

introduction: insome cases, assist devices are required to ensure an adequate cardiac output after cardiac surgery. intra-aortic balloon pump (iabp) is the most commonly used cardiac assist device, which provides first-line support for patients with heart failure. the aim of this study was to determine factors affecting the mortality rate of patients receiving iabp. materials & methods:  in thi...

conclusions our anesthesia method was sciatic and femoral nerve block under double ultrasonic and nerve stimulator guidance. case presentation in this case report, we present a patient who had tibia and fibula fractures and a symptomatic severe critical aortic stenosis which was diagnosed during a preoperative visit. the patient had exertional dyspnea, palpitations and fainting history, but he ...

a 32-year-old female patient with previous bentall operation and mitral valve repair surgery due to severe aortic insufficiency, mitral valve insufficiency, and ascending aortic aneurysm was admitted to our hospital with serious dyspnea, fatigue, and mild chest pain. two-dimensional echocardiography demonstrated a markedly dilated basal aorta and cardiac chambers. thoracic computed tomography s...

behcet’s disease is a rare immune mediated systemic vasculitis which besides it’s more frequent involvement of eyes and skin,   sometimes present with aortic pseudo aneurysm and more rarely cardiac inflammatory masses.a 51-year-old patient with behçet’s disease presented with two symptomatic aortic pseudoaneurysms concomitant with a right atrial mass. computed tomography (ct) revealed one supra...

during 15 years from 1975 to 1990, thirteen cases of supravalvar aortic stenosis were admitted at the pediatrics department of shahid rajai heart hospital, tehran. all patients were subjected to cardiac catheterization and a angiocardiography. patients ranged in age from 3.5 years to 14 years with a mean of 8.7 years. seventy seven percent of childen were male. eight cases (61.5%) had williams&...

Thrombotic events are very unusual in neonatal period. This congenital anomaly may be caused by certain risk factors such as polycythemia, perinatal asphyxia, septicemia, maternal diabetes, dehydration, and low cardiac output, or it may occur upon catheterization of central lines. A 20-day-old neonate was referred to our ward with primary signs of hypertrophic cardiomyopathy (HCMP). Echocardiog...

Aortic valve repair with either the reimplantation of aortic or root remodelling external annuloplasty procedure is most effective means treating regurgitation and/or aneurysms [...]

background: the vascular function of angiotensin ii-type-2 receptors in adults is controversial. we sought their location and function in mouse aortic rings at young and old mice. materials and methods: male c57bl mice (aged 4 and 14 months) were killed by co2. the descending thoracic aorta was cleaned and dissected into rings. aortic rings were mounted in krebs’ solution at 37 °c and then setu...

introduction: postoperative neurological deficit is the most devastating complication after thoracoabdominal aortic aneurysm repair. despite demonstrated neuroprotective effects of estradiol, its protective efficacy against spinal cord ischemia-reperfusion and underlying mechanisms are not yet elucidated. methods: two groups, each of 10 new zealand white male rabbits, were studied. control grou...
