quadricuspid aortic valve (qav) is an uncommon congenital anomaly which was an incidental finding during surgery or autopsy in the past. we present the case of a 44-year-old woman with moderately severe aortic regurgitation due to unequal cusp size qav diagnosed via transesophageal echocardiography. due to echocardiographic imaging improvement, the diagnosis of qav is now easier and earlier tha...

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...

Bicuspid aortic valve is traditionally considered an innocuous congenital anomaly. Due to a better and widespread availability of non-invasive imaging techniques, it has come to the fore that 30% of these cases develop complications, viz., valve abnormality (aortic regurgitation and stenosis), and aneurysm of aortic root and ascending aorta. Sinus of Valsalva aneurysm is an uncommon complicatio...

  Introduction: Aortic valve sclerosisis considered as a manifestation of coronary atherosclerosis. Recent studies demonstrated an association between aortic valve sclerosis and obstructive coronary artery disease. The purpose of this study was to evaluatethe correlation betweenaortic valve sclerosis andobstructive coronary artery disease and the extent of coronary artery disease in patients ho...

a 46 year old man had been undergone aortic valve replacement (avr) due to mechanical aortic valve endocarditis two month ago. he was referred to imam khomeini hospital because of dyspnea since two weeks ago. echocardiography showed the false aneurysm, with an area of flow beyond the lumen of the aorta. this patient underwent reoperation, the previously implanted aortic valve was removed, metic...

in recent socio-economic state it is not possible to have different sets of prosthetic cardiac valves available in the operating room before open-heart surgery for valvular replacement. in this study the diameter of the aortic valve ring measured in 2-d echocardiography was compared with the size of the aortic prosthetic valves implanted for the patients with aortic valvular disease. the purpos...
