Individuals with a bicuspid aortic valve (BAV) are at significantly higher risk of developing aortic complications than individuals with tricuspid aortic valves (TAV) and defective signaling during the embryonic development and/or life time exposure to abnormal hemodynamic have been proposed as underlying factors. However, an explanation for the molecular mechanisms of aortopathy in BAV has not yet been provided. We combined proteomics, RNA analyses, immunohistochemistry, and electron microscopy to identify molecular differences in samples of non-dilated ascending aortas from BAV (N = 62) and TAV (N = 54) patients...

Interrupted aortic arch is a rare congenital abnormality with a high infancy mortality rate. The principal finding is loss of luminal continuity between the ascending and descending portions of the aorta. Because of the high mortality rate in infancy, interrupted aortic arch is very rare among adults. In this report, we describe the case of a 76-year-old woman with asymptomatic interrupted aortic arch, severe tricuspid regurgitation, and bicuspid aortic valve. To our knowledge, she is the oldest patient ever reported with this possibly unique combination of pathologic conditions...

BACKGROUND: Although aortic valve-sparing (AVS) operations are established alternatives to composite valve graft (CVG) procedures for patients with aortic root aneurysms, comparative long-term outcomes are lacking. OBJECTIVES: This study sought to compare the results of patients undergoing AVS procedures with those undergoing CVG operations. METHODS: From 1990 to 2010, a total of 616 patients age <70 years and without aortic stenosis underwent elective aortic root surgery (AVS, n = 253; CVG with a bioprosthesis [bio-CVG], n = 180; CVG with a mechanical prosthesis [m-CVG], n = 183)...

This study evaluated the myocardial strain and aortic elasticity in patients with bicuspid aortic valve (BAV) and then investigated the relation between them. Thirty-nine patients (30 males; mean age 44±19 years; range 6 to 75 years) with BAV were recruited as BAV group, and 29 age- and sex-matched healthy controls (21 males; mean age 42±11 years; range 20 to 71 years) served as control group. Aortic strain, distensibility and stiffness index were derived using M-mode echocardiography. Left ventricular global myocardial strain was acquired with speckle-tracking echocardiography...

An 84-year-old man with cardial senile amyloidosis and severe tricuspid regurgitation was referred for right sided heart failure symptoms. The patient was scheduled for a percutaneous treatment due to the prohibitive risk of surgery. Two MitraClips were implanted using a transjugular approach with successful echocardiographic and clinical results. This case shows the rational of the procedural with a bicuspidalization of the valve demonstrated at the three dimensional transesophageal echocardiography.

Hypoplastic right heart syndrome is a rare cyanotic congenital heart disease with under-development of the right ventricle, tricuspid, and pulmonary valves leading to right-to-left shunting of the blood through inter-atrial septal defect. Perinatal mortality is high with very few patients surviving to adulthood without corrective surgery. This report describes a 26-year-old young woman, who had recurrent abortions and stillbirths and detected to have marked cyanosis with hypoplastic right heart, sub-arterial ventricular septal defect, absent pulmonary valve, non-compaction of the left ventricle, and bicuspid aortic valve with aortic regurgitation...

Bicuspid aortic valve (BAV) is a common congenital cardiac anomaly, and rarely, it is associated with sinus of Valsalva aneurysms (SOVAs). And very infrequently, these SOVAs rupture into left side of heart. We hereby report a case of 12-year-old male with BAV with severe aortic stenosis with a large SOVA that ruptured into the left side of the heart. The anatomy was delineated with multimodality imaging; initially with two-dimensional trans-thoracic echocardiography (TTE), and later on with three-dimensional TTE and with multi detector computed tomography...

BACKGROUND: In a patient underwent aortic valve replacement (AVR) due to bicuspid aortic valve (BAV) insufficiency without marked dilation of ascending aorta, the development of delayed-typed aneurysmal complication of ascending aorta has been often reported because the dilated aorta tends to grow insidiously with age. CASE SUMMARY: A 58-year-old man who underwent AVR with mechanical valve due to severe aortic regurgitation secondary to BAV 7 years previously presented with exertional chest discomfort for 1 year...

BACKGROUND: Aortic dissection in pregnancy is relatively rare, but it is often fatal. The estimated incidence of aortic dissection in the general population is 2.9 per 100,000 person-years. Early recognition and treatment of aortic dissections are crucial for survival. Whereas the majority of patients who present with aortic dissection are older than 50 years of age and have a history of hypertension, younger patients with connective tissue disease, bicuspid aortic valves, or a family history of aortic dissection are also at increased risk for developing this condition...

A comprehensive understanding of the normal and abnormal aortic root is paramount if we are to improve not only our assessment of the aortic root and its components but also the surgical approach to reconstructing this complex structure when congenitally malformed. Most anatomic and imaging-based classifications of the normal root recognize and describe the basic components, which include the shape and size of the three aortic sinuses and their three valvar leaflets, as well as the sinutubular junction and proximal ascending aorta...

BACKGROUND: The presence of coronary artery ectasia (CAE) is influenced by genetic factors and related to the presence of aneurysms in other vascular beds. Bicuspid aortic valve (BAV) disease is frequently accompanied by ascending aortic aneurysm. Because the aortic valve and the proximal parts of the coronary arteries share a common embryonic origin, we hypothesized that CAE is associated with BAV disease. METHODS AND RESULTS: One hundred seventy-seven patients with suspected aortic valve disease (n=94 BAV, n=83 tricuspid aortic valve) underwent both cardiac magnetic resonance imaging and coronary angiography...

The aim of this study was to compare frictional resistance among conventional, passive and active selfligating brackets using Finite Elements Analysis (FEA). Seventynine (79) slide tests were performed by combining an upper first bicuspid conventional bracket, 0.018" stainless steel wires and 0.010" ligature by means of an INSTRON 3345 load system to obtain average maximum static frictional resistance (MSFR). This value was compared to the FR (frictional resistance) obtained by simulation of a slide of the same combination by FEA following conventional bracket modeling by means of Computer Aided Design (CAD)...

BACKGROUND: After aortic valve replacement (AVR), bicuspid aortic valve (BAV) patients continue to be at risk of aortic complications. Therefore, knowledge of native valve anatomy is important for follow-up. We aimed to determine the extent of which the presence of BAV disease is known in a regional post-AVR population. METHODS: The Electronical Medical Record system was used to collect all patients under follow-up after AVR. We documented their clinical data and used the operative report to determine valve phenotype; lacking reports were retrieved...

Bicuspid aortic valve (BAV) disease is the most common congenital cardiac abnormality and predisposes patients to life-threatening aortic complications including aortic aneurysm. Quantitative real-time reverse transcription PCR (qRT-PCR) is one of the most commonly used methods to investigate underlying molecular mechanisms involved in aortopathy. The accuracy of the gene expression data is dependent on normalization by appropriate housekeeping (HK) genes, whose expression should remain constant regardless of aortic valve morphology, aortic diameter and other factors associated with aortopathy...

Unicuspid aortic valve (UAV) is an extremely rare form of congenital aortic valvular abnormality. Although UAV shows similar clinical characteristics to bicuspid aortic valve, the clinical symptoms develop at earlier age and progress at a faster pace in UAV. In this report, we are presenting a 42-year-old male with severe aortic stenosis associated with unicommissural UAV. The patients underwent a successful Bentall operation.
