Progression of ascending aortic dilatation in congenital bicuspid aortic valve as characterised by cardiovascular magnetic resonance
نویسندگان
چکیده
Methods A retrospective analysis of serial Asc Ao dimension was made of 31 patients (mean age 46±14, 68% male and 32% female) with BAV who underwent at least 2 cardiovascular magnetic resonance imaging study (CMR) > 4 months apart from January 2002 to September 2012 at the Royal Brompton Hospital. Patients with associated aortic coarctation or aortic valvular dysfunction were excluded. Images were acquired with either a Siemens Avanto or Siemens Sonata scanner. Maximal intraluminal Asc Ao diameters at the level of right pulmonary artery (RPA) were measured in end diastole using the axial single-shot spin-echo (HASTE) sequence. The rate of change in aortic dimension per year was calculated.

Bicuspid Aortic Valve: An Unusual Cause of Aneurysm of Left Coronary Sinus of Valsalva
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...

BACKGROUND Congenital bicuspid aortic valve (BAV) is a significant risk factor for serious complications including valve dysfunction, aortic dilatation, dissection, and sudden death. Clinical tools for identification and monitoring of BAV patients at high risk for development of aortic dilatation, an early complication, are not available. METHODS This paper reports an investigation in 18 pedi...

AIMS Bicuspid aortic valve (BAV) represents the most frequent congenital cardiac abnormality resulting in premature valvular degeneration and aortic dilatation. In a large series of consecutive patients, we evaluated the distribution of BAV types and the associated valvular and aortic abnormalities. METHODS AND RESULTS We investigated 266 patients (58 ± 14 years) with BAV using a 1.5 T cardia...

متن کاملDilation of the ascending aorta in Turner syndrome - a prospective cardiovascular magnetic resonance study
BACKGROUND The risk of aortic dissection is 100-fold increased in Turner syndrome (TS). Unfortunately, risk stratification is inadequate due to a lack of insight into the natural course of the syndrome-associated aortopathy. Therefore, this study aimed to prospectively assess aortic dimensions in TS. METHODS Eighty adult TS patients were examined twice with a mean follow-up of 2.4 ± 0.4 years...
