BACKGROUND: Left ventricular (LV) function and the dimensions of aortic valves from normally functioning bicuspid aortic valve (BAV) patients were compared with those of healthy control patients. A comparison between patients with antero-posterior BAV (BAV-AP) or right-left BAV (BAV-RL) was also performed, and the determinants of aortopathy and LV function were investigated. METHODS: Sixty-eight patients with aortic velocities <2 m/s and trivial or mild aortic regurgitation were included in the study...

A normally functioning bicuspid aortic valve that is spared during replacement of the ascending aorta may ultimately require replacement due to structural deterioration. We report the use of trans-aortic valve replacement to replace a stenotic BAC 17 years following replacement of the ascending aorta.

BACKGROUND AND AIM: Acute endocarditis (AE) is still rare disease in pediatric population, nevertheless the children suffering from AE usually need heart valves repair or replacement in emergency settings. METHODS: We present a case of emergency mitral valve replacement with the use of Melody balloon expandable stented bioprosthesis in a 2-years-old patient with acute endocarditis, subsequent mitral (bicuspid) valve incompetence after aggressive infective destruction with the symptoms of critical multiorgan failure...

Bicuspid aortic valve (BAV) is a heritable congenital heart defect and an important risk factor for valvulopathy and aortopathy. Here we report a genome-wide association scan of 466 BAV cases and 4,660 age, sex and ethnicity-matched controls with replication in up to 1,326 cases and 8,103 controls. We identify association with a noncoding variant 151 kb from the gene encoding the cardiac-specific transcription factor, GATA4, and near-significance for p.Ser377Gly in GATA4. GATA4 was interrupted by CRISPR-Cas9 in induced pluripotent stem cells from healthy donors...

BACKGROUND: Standard cine-cardiac magnetic resonance (CMR) imaging is commonly used to evaluate cardiac structure, geometry and function. Prior studies have shown that automated segmentation via partial voxel interpolation (PVI) accurately quantifies phantom-based cardiac chamber volumes and necropsy left ventricular myocardial mass. Despite this, the applicability and usefulness of PVI in the determination of physiologic parameters of the aorta such as aortic stiffness has yet to be investigated...

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 complication of bicuspid aortic valve and more so those arising from the left coronary sinus are the rarest. These complications generally occur in the third or fourth decade of life...

As transcatheter aortic valve replacement has become an alternative treatment for patients at high risk for surgical aortic valve replacement, bicuspid aortic valve (BAV) draws our attention again. The reported frequency of BAV was 0.5% to 2% in western population. However, there was no such epidemiologic study in Chinese population. Our study sought to investigate the prevalence and complications of BAV in China by echocardiographic database. A total of 668 cases who were confirmed with BAV, identified from 195,708 echocardiographic records of 157,039 patients in the echocardiographic database of West China Hospital (between June 2008 and June 2012), were analyzed retrospectively...

BACKGROUND: Tetralogy of Fallot (TOF) is a complex congenital heart disease with anatomic variations. Although the pulmonary valve in TOF is abnormal, it has not been studied well, especially on newer imaging modalities such as multidetector computed tomography (CT), which gives excellent anatomic detail. AIMS: The aim of this study was to assess the morphology of pulmonary valve in TOF on CT and evaluate its association with the degree of hypoplasia of infundibulum and pulmonary trunk...

The therapeutic implications of bicuspid aortic valve associations have come under scrutiny in the transcatheter aortic valve implantation era. We evaluate the spectrum of mitral valve disease in patients with bicuspid aortic valves to determine the need for closer echocardiographic scrutiny/follow-up of the mitral valve. A retrospective analysis of echocardiograms done at a referral hospital over five years was conducted in patients with bicuspid aortic valves with special attention to congenital abnormalities of the mitral valve...

BACKGROUND: Incorporation of bone substitute material into the extraction socket could minimize the edentulous ridge volume loss or maximize the bone formation within the healing area. PURPOSE: The aim of the study was to test the effectiveness in maintaining the volumetric contour of fresh extraction sockets grafted with or without 2 types of porcine biomaterials and covered with a resorbable barrier. MATERIALS AND METHODS: In the present multi-center single-blind randomized control trial, 55 patients underwent 1-tooth extraction, were surveyed, and randomly allocated to control- (25 sites, nat-group) or test groups (15 sites grafted with pre-hydrated collagenated cortico-cancellous porcine bone, coll-group, and 15 with cortical porcine bone, cort-group)...

BACKGROUND: Ascending aorta dilatation is common in bicuspid aortic valve (BAV). The aim of this study was to investigate agreement of transthoracic echocardiographic (TTE) measurement of the sinuses of Valsalva and the tubular mid-ascending aorta (Asc-Ao) compared with electrocardiographically gated computed tomographic angiographic (CTA) assessment in patients with BAV. METHODS: Fifty-three patients with BAV (mean age, 54 ± 14 years; 74% men) who underwent both TTE and CTA imaging for ascending aortic assessment were retrospectively identified...

Ahmad Masri, Lars G Svensson, Brian P Griffin, Milind Y Desai
We performed a systematic review of the current state of the literature regarding the natural history and outcomes of bicuspid aortic valve (BAV). PubMed and the reference lists of the included articles were searched for relevant studies reporting on longitudinal follow-up of BAV cohorts (mean follow-up ≥2 years). Studies limited to patients undergoing surgical interventions were excluded. 13 studies (11 502 patients with 2-16 years of follow-up) met the inclusion criteria. There was a bimodal age distribution (30-40 vs ≥50 years), with a 3:1 male to female ratio...

AIMS: The aim of this study was to evaluate the clinical and echocardiographic results and the predictors of outcomes in patients undergoing valve-sparing operation (VSO) at two aortic centers. In addition, we sought to evaluate the potential effect of recreation of the sinuses of Valsalva (SV) on the outcome of valve-sparing procedures. METHODS: During a 14-year period, 328 patients underwent aortic valve-sparing root replacement at two institutions. Clinical and echo evaluation was performed 6 months after surgery and every year thereafter or in case of clinical symptoms...

Knowledge of aortic growth in patients with bicuspid aortic valve (BAV) is essential to identify patients at risk for dissection, but data on children remain unclear. We retrospectively evaluated the aortic diameters of all pediatric BAV patients, identified through an echocardiographic database (2005 to 2013). Medical records were reviewed and aortic diameters re-measured on echocardiographic images at diagnosis and if available on variable mid- and endpoints follow-up. Dilatation (z-score >2) was based on 2 different z-score equation methods (Gautier/Campens)...

Ebstein's anomaly is defined as the significant apical displacement of the tricuspid valve causing tricuspid regurgitation. Although a variety of concomitant lesions have been previously described, we herein introduce an unusual presentation. Our patient was an 86-year-old man with a primary presentation of typical chest pain in the setting of recently diagnosed coronary artery disease with concomitant Ebstein's anomaly. We found mild-to-moderate tricuspid regurgitation, bicuspid aortic valve, persistent left superior vena cava, and patent foramen ovale...
