Aortic root dilatation was sought by echocardiography and radiology in 500 consecutive patients referred to an echocardiography laboratory from cardiac or medical clinics and wards. Forty-four of these patients (8.8%) had false echocardiographic evidence of aortic root dissection, but no clinical evidence of the disease. These false findings were attributed to the changing of the transducer ang...

We have developed a method for constructing the geometry of morphologically realistic human aorta, including aortic root (Valsalva sinus), thoracic arch with branches, abdominal aorta bifurcation vessels. The creation three-dimensional model is necessary when planning surgical interventions, performing numerical modeling blood flow in aorta. anatomical structure differs different patients, espe...

Aortic dissection occurs when a tear develops in the wall of the aorta, which is rare in the young population. This fatal disorder is hard to diagnose, especially in young patients. We present the case of aortic dissection in a 15-year-old boy referred to the Emergency Department of Yazd University of Medical Sciences in November 2015. The patient presented to our department with sudden acute c...

OBJECTIVES Sinuses of Valsalva are important in assuring the physiological function of the aortic valve. This study evaluates short-term clinical results of the reimplantation technique for aortic valve-sparing root replacement using a new prosthesis with three separate sinuses of Valsalva (sinus prosthesis). METHODS Between February 2009 and February 2011, a total of 23 patients (20 m/3 f; m...

BACKGROUND The aorta is considered pathologically dilated if the diameters of the ascending aorta and the aortic root exceed the norms for a given age and body size. A 50% increase over the normal diameter is considered aneurysmal dilatation. Such dilatation of the ascending aorta frequently leads to significant aortic valvular insufficiency, even in the presence of an otherwise normal valve. T...

BACKGROUND The Ross operation is an alternative to mechanical aortic valve replacement in the young. Early dilatation of the pulmonary autograft root exposed to the systemic circulation has been reported. To define the prevalence of, risk factors for, and consequences of late autograft dilatation, outcome in all consecutive patients operated since May 1994 was reviewed. METHODS AND RESULTS Ni...

A 40-year-old man with bicuspid aortic valve and huge LV CLINICAL INTRODUCTION A 40-year-old man presented to our institute with progressive exertional dyspnoea for 1 year. Bicuspid aortic valve (BAV) with mild-to-moderate aortic regurgitation (AR) was diagnosed in his childhood by echocardiography, but he declined follow-up after-wards. Physical examination revealed a grade 3/6 'to-and-fro' mu...

A 3-year-old boy being followed up for bilateral club foot underwent a routine thorax radiography that revealed aortic arch enlargement. Echocardiography showed sinus of Valsalva dilatation. Because of clinical features such as hypertelorism, bifid uvula, and prominent forehead, a genetic investigation was conducted that confirmed Loeys-Dietz syndrome (LDS) by identifying a heterozygous mutatio...

Introduction: Iatrogenic aortocoronary dissection (ACD) is a nightmare in interventional cardiology. Although ACD is rarely reported, the real-world prevalence is suspected of being higher due to unreported cases. The right coronary artery (RCA) ostium is involved in the majority of cases, and dissections are usually limited to the aortic sinus in half of the clinical presentat...
