Objective: Minimal invasive endodontics preserve coronal and radicular tooth structure to increase the fracture resistance of teeth. The aim of this study was to assess the influence of final preparation taper on the fracture resistance of maxillary premolars. Materials and Methods: Sixty maxillary premolars were selected and divided into 2 groups: 30 were shaped with a final apical diameter 30 and a 4% taper and 30 with 6% taper using iRaCe® instrument (FKG dentaire, Switzerland)...

OBJECTIVES: This study sought to ascertain whether patients with a bicuspid aortic valve (BAV) have an intrinsic alteration in regional aortic stiffness compared with patients with tricuspid aortic valve (TAV) and Marfan syndrome (MFS) patients with similar aortic sizes, as well as to assess the influence of ascending aorta (AAo) dilation on regional stiffness parameters in BAV patients. BACKGROUND: Imaging biomarkers as predictors of BAV, MFS, and degenerative AAo aneurysms in TAV patients (DA-TAV) are lacking...

Turner syndrome (TS) is a common genetic disorder in females with high incidence of ascending aortic dilatation and even dissection occurring as early as in the second decade. Known risk factors (RF) are bicuspid aortic valves (BAV), coarctation of the aorta (CoA), and arterial hypertension. Since 10% of dissections occur in patients without RF, an intrinsic aortic wall abnormality has been postulated. This study aimed to investigate the elasticity of the ascending aorta as a surrogate marker of aortic wall texture...

The NOTCH signalling pathway is an essential pathway, involved in many cellular processes, including cell fate decision, cell proliferation, and cell death and important in the development of most organs. Mutations in genes encoding components of the NOTCH signalling pathway lead to a spectrum of congenital disorders. Over the past decades mutations in human NOTCH signalling genes have been identified in several diseases with cardiovascular involvement. NOTCH1 mutations have been described in bicuspid aortic valve disease, left-sided congenital heart disease, and Adams-Oliver syndrome...

BACKGROUND: This meta-analysis compares the early and late outcomes of valve repair versus replacement, the primary surgical strategies for tricuspid valve infective endocarditis (IE). METHODS: We searched MEDLINE and EMBASE databases until 2016 for studies comparing tricuspid valve repair and replacement. RESULTS: The main outcomes were mortality, recurrent IE and need for reoperation. There were 12 unmatched retrospective observational studies with 1165 patients (median follow up 3...

BACKGROUND: The optimal arterial cannulation site in patients undergoing surgical management of acute type A aortic dissection (ATAAD) remains controversial. The axillary artery is rarely involved in the dissection process, provides antegrade flow in the descending aorta and minimises intraoperative malperfusion. The purpose of this study is to evaluate a single surgeon's experience of axillary artery cannulation for ATAAD repair. METHODS: All consecutive patients over a 15-year period having surgical repair of ATAAD were included in this study...

We present the case of transcatheter aortic valve replacement in a 20-year-old woman with severe bicuspid aortic stenosis and Schmike immuno-osseous dysplasia who was unfit for surgical aortic valve replacement. Meticulous pre-procedural planning and a multidisciplinary team approach can enable successful transcatheter aortic valve replacement in complex patients with genetic syndromes.

BACKGROUND: A sternal-sparing approach to surgery of the proximal aorta could decrease postoperative morbidity. METHODS: To determine the potential benefits of using a minimally invasive right thoracotomy approach for the treatment of ascending aortic pathology, we retrospectively reviewed our experience in patients who required circulatory arrest for the treatment of ascending aortic pathology (with or without aortic valve involvement) between January 2009 and November 2014 (N=177)...

We present two cases of severe aortic coarctation detected in adulthood and who underwent successful relief by transcatheter stent deployment using a new covered stent, Optimus® stent (AndraTec GmbH Koblenz, Germany). One patient is a 46-year old female with resistant arterial hypertension, in whom coarctation was suspected on a follow-up transthoracic echocardiogram for bicuspid aortic valve disease and subsequently confirmed on magnetic resonance imaging. The second patient is a 68-year old male whose coarctation was diagnosed incidentally at coronary angiography being performed as part of the preoperative work-up for severe aortic stenosis...

The prevalence of congenital and acquired heart disease in patients with the Turner syndrome (TS) is based on historic cohorts who underwent imaging before the advent of modern day echocardiography. Recent small studies suggest a higher prevalence of cardiac defects. We reviewed clinical and echocardiographic data on 564 girls and women with TS to assess the prevalence of cardiac defects. Echocardiographic review on a subset of this population was performed to assess for diagnostic limitations of echocardiography in assessing for congenital and acquired defects in this patient cohort...

BACKGROUND: Although rheumatic heart disease remains the leading cause of valve heart disease (VHD) in developing countries, other forms of valve disease have been over shadowed and not regarded as a public health problem. However, several facts suggest that the role of non-rheumatic VHD as a significant cardiovascular disease should be reconsidered. We aimed to assess the prevalence and characteristics of different forms of primary left sided valve diseases from a series of 15,009 echocardiographic studies...

The current iterations of balloon-expandable transcatheter aortic valve replacement (TAVR) valves consist of a maximum size of 29 mm, corresponding to maximum annulus area of 680 mm2 . However, a number of patients who qualify for TAVR based on surgical risk may have anatomical features outside the FDA-approved descriptions. The technique of overexpansion of TAVR valves during deployment allows for more patients to be treated successfully. This particular case demonstrates that overexpansion is safe and efficacious in a very large annulus of >800 mm2 ...

INTRODUCTION: Infective endocarditis (IE) remains a dangerous condition with considerable associated mortality. Usual risk factors for IE include the presence of a prosthetic heart valve, structural or congenital heart disease, intravenous drug use, and a recent history of invasive procedures. METHODS: The authors describe the case report of a patient with IE having trauma as an unusual risk factor. RESULTS: A 33-year old male patient was referred to our department due to infective endocarditis...

INTRODUCTION: Bicuspid aortic valve (BAV) is the single most common cardiac congenital mal-formation with a prevalence of 1-2%. It is frequently associated with aortic disease including annular ectasia. Increasing evidence suggests that valve-sparing root re-implantation surgery combined with primary aortic valve repair can be performed with good midterm results in patients with BAV. METHODS: Our objective is to compare the short and long term results of David procedure in BAV patients with aortic root ectasia...

INTRODUCTION: Bicuspid aortic valves are associated with histopathological abnormalities of the aorta. Their diameters have been measured in several studies, but the literature concerning changes in the overall anatomy of the ascending aorta is limited. We wanted to know whether the anatomy of the valve, bicuspid or tricuspid, is associated with anatomical differences. MATERIALS AND METHODS: We prospectively included patients requiring aortic valve surgery. The protocol included a chest CT scan before the operation to determine the angulations and straight lengths of aortic segments 0 and 1...

BACKGROUND: Recent guidelines support more aggressive surgery for aneurysms of the ascending aorta and root in patients with bicuspid aortic valve. However, the fate of the arch after surgery of the root and ascending aorta is unknown. We set out to assess outcomes following root and ascending aortic surgery and subsequent growth of the arch. METHODS: Between 2005 and 2016, 536 consecutive patients underwent surgery for aneurysm of the root and ascending aorta. 168 had bicuspid aortic valve...
