OBJECTIVE: Aortic valve-in-valve implantation for prosthetic valve dysfunction is a good alternative to reoperative valve replacement. There are some limitations to this approach including the risk of coronary occlusion, patient prosthesis mismatch, and valve malposition. The incidence of coronary occlusion is higher in aortic valve-in-valve than de novo aortic stenosis cases. Multiple factors can contribute to this complication, and the type of bioprosthesis has been implicated. METHODS: We examined our experience of 80 aortic valve-in-valve cases with internally and externally mounted leaflet valves...

Cor-triatriatum is uncommon and cor-triatriatum dexter is rarer, and patients may remain asymptomatic in isolated cases especially if the partitioning is mild and nonobstructing. There may be other cardiac defects associated with it which are mostly right-sided cardiac defects such as atrial septal defect, Ebstein anomaly, and pulmonary stenosis. However, left-sided heart anomaly such as aortic regurgitation has been associated with it, but its association with transposition of the great vessels has not been documented before now...

Background: Bicuspid aortic valve (BAV) is the most common congenital heart disease, affecting 0.5%-2% of the general population. It is associated not only with notable valvular risk (aortic stenosis and/or regurgitation, endocarditis) but also with aortopathy with a wide spectrum of unpredictable clinical presentations, including aneurysmal dilation of the aortic root and/or ascending thoracic aorta, isthmic coarctation, aortic dissection, or wall rupture. Methods: The REgistro della Valvola Aortica Bicuspide della Società Italiana di ECocardiografia e CArdiovascular Imaging is a retrospective (from January 1, 2010)/prospective, multicenter, observational registry, expected to enroll 3000 patients with definitive diagnosis of BAV made by transthoracic and/or transesophageal echocardiography, computed tomography, cardiovascular magnetic resonance, or at surgery...

OBJECTIVES: Acute Kidney Injury (AKI) after open aortic repair is subject to multiple patient- and operation-related variables. Hostile neck morphology in open aneurysm repair is thought to contribute to this AKI risk post-operatively. The aim of this study was to evaluate if large neck atheroma is a possible risk factor in the postoperative development of AKI. METHODS: Retrospectively 137 patients were evaluated for neck atheroma and AKI incidence. Atheroma load measurements were performed by two different techniques...

This report presents the case of an 82 year old male with known dextrocardia and situs inversus totalis who developed increasing dyspnea on exertion and was diagnosed with severe aortic stenosis. Transcatheter aortic valve replacement was decided upon requiring deviation from standard techniques for patients with normal anatomy and left-sided aortic arch. We describe two technical differences required for patients with dextrocardia and right-sided aortic arch which facilitate transcatheter aortic valve replacement in this patient group...

Mitral annular calcification can pose a formidable surgical challenge in the setting of mitral valve replacement for mitral stenosis. Although there are reports of transapical valve-in-valve transcatheter mitral valve replacement in the setting of degenerated bioprosthetic mitral valve replacement, there is less experience with transcatheter mitral valve replacement for mitral annular calcification. This report describes a patient who previously received a transcatheter aortic valve replacement and then subsequently underwent a minimally invasive right thoracotomy for transcatheter mitral valve replacement with a successful result...

OBJECTIVES: There are substantial potential benefits to noninvasive cardiac monitoring methods, such as electrical cardiometry (EC), over more invasive methods, including significantly reduced risk of complications, lower up-front and operational costs, ease of use, and continuous monitoring. To take advantage of these technologies, clinical equivalence to currently established methods must be determined. The authors sought to determine if the noninvasive measurement of cardiac index (CI) by EC was clinically equivalent to thermodilution (TD) in adult patients with aortic stenosis (AS)...

BACKGROUND AND AIMS: Genetic factors play an important role in the cervico-cerebral large-artery atherosclerotic stenosis (LAS), and ATP2B1 gene has been associated with the process of atherosclerosis disorders, such as coronary artery disease and arterial stiffness. But there is little information about the relationship between ATP2B1 gene and atherosclerosis in the intracranial arteries. We hereby investigated the association of common variants in ATP2B1 gene with LAS in asymptomatic Chinese hypertension patients...

Purpose: 3D printed patient specific vascular models provide the ability to perform precise and repeatable benchtop experiments with simulated physiological blood flow conditions. This approach can be applied to CT-derived patient geometries to determine coronary flow related parameters such as Fractional Flow Reserve (FFR). To demonstrate the utility of this approach we compared bench-top results with non-invasive CT-derived FFR software based on a computational fluid dynamics algorithm and catheter based FFR measurements...

BACKGROUND: Antithrombotic treatment regimen following transcatheter aortic valve replacement (TAVR) is not evidence-based. Apixaban, a non-vitamin K direct anticoagulant (NOAC) was shown to be superior to VKA and superior to aspirin to prevent cardioembolic stroke in non-valvular atrial fibrillation. It may have the potential to reduce TAVR-related thrombotic complications including subclinical valve thrombosis along with a better safety than the standard of care. DESIGN: ATLANTIS is a multicenter, randomized, phase IIIb, prospective, open-label, superiority study comparing standard of care (SOC Group) versus an apixaban-based strategy (Anti-Xa Group) after successful TAVR (ClinicalTrials...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) has become an alternative treatment to surgery in patients with severe aortic stenosis (AS). However, patients with Bicuspid aortic stenosis (BiAV) are usually excluded from major TAVR studies. The aim of this study is to reexamine the current evidence of TAVR in patients with severe AS and BiAV comparing to tricuspid aortic valve (TriAV). METHOD: Databases were systematically searched for relevant articles according to the following criteria...

A 77 year old male underwent elective bioprosthetic aortic valve replacement (23mm Carpentier-Edwards Perimount MagnaEase) for severe aortic stenosis. His pre-discharge transthoracic echocardiogram (TTE) was normal. He presented 9 days after surgery with dyspnoea and fever. He was in sinus rhythm. Blood cultures were taken and he was commenced on empirical antibiotics for possible infective endocarditis (subsequently all negative). Repeat TTE showed a well-seated prosthesis without regurgitation but elevated gradients (peak / mean gradients 49 / 22 mmHg respectively)...
