BACKGROUND Patients with bicuspid aortic valve (BAV) have been frequently complicated with ascending aortic dilation possibly because of hemodynamic burdens by aortic stenosis (AS) or regurgitation (AR) or congenital fragility of the aortic wall. METHODS AND RESULTS To clarify if the aortic dilation could be prevented by aortic valve replacement (AVR) in BAV patients, we studied 13 BAV (8 AR ...

While acute regurgitation is the most common valvular lesion associated with aortic sinus of Valsalva aneurysms, this report describes the pathological findings in five patients in whom primary right-sided valve dysfunction was simulated by sinus of Valsalva aneurysms. In two patients aneurysms of the noncoronary sinus projected into the right atrium at the level of the tricuspid valve and caus...

Aortic dissection (AD) is a life-threatening condition and may present with symptoms which mimic myocardial infarction, leading to misdiagnosis and inappropriate use of anticoagulant and thrombolytic therapy. A 40-year-old woman with no prior history presented in our emergency department with sudden chest pain. Electrocardiography (ECG) showed a ST-segment elevation in leads II, III and avF, su...

aorta is formed in a dynamic environment which gives rise to imbalances between many forces that tend to extend the diameter and length. furthermore, internal forces tend to resist this extension. impedance tomography can show this imbalance to stimulate the stenosis of aortic valve, growth of the elastic, collagen and to effectively reduce the stresses in the underlying tissue. in blood flow, ...

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...

Dissection of the sinus of Valsalva is an extremely rare accident during percutaneous coronary intervention (PCI), but it can lead to serious complications such as dissection of the ascending aorta. We experienced a localized dissection of the right coronary cusp without coronary artery involvement that was induced by a guiding catheter during PCI in a patient with acute myocardial infarction. ...

INTRODUCTION Though computed tomographic angiography has very high sensitivity and specificity to diagnose acute aortic dissection, false-negative studies can occur and secondary tests may be required to make the diagnosis. CASE PRESENTATION We report the case of a 57-year-old Caucasian man with a typical presentation for acute type A aortic dissection in whom the initial non-cardiac gated co...

We describe a case of ruptured sinus of Valsalva aneurysm (RSVA) with moderate aortic regurgitation (AR), which developed on the second day after admission. The AR was caused by a hemodynamic effect solely, in which the shunt blood flow through ruptured site pulled the right aortic cusp away from closure. The pathological mechanism of the AR was clearly visualized by intraoperative transesophag...

BACKGROUND The modern imaging techniques of transesophageal echocardiography, CT, and MRI are reported to have up to 100% sensitivity in detecting the classic class of aortic dissection; however, anecdotal reports of patient deaths from a missed diagnosis of subtle classes of variants are increasingly being noted. METHODS AND RESULTS In a series of 181 consecutive patients who had ascending o...

OBJECTIVE The clinical manifestations of acromegalic cardiomyopathy include arrhythmias, valvular regurgitation, concentric left ventricular (LV) hypertrophy, and LV systolic and diastolic dysfunction. At present, it is unknown whether acromegaly also affects the aortic root. DESIGN Aortic root diameters were prospectively assessed in 37 acromegalic patients (18 patients with active disease a...
