BACKGROUND: Patients undergoing transcatheter aortic valve replacement (TAVR) are often characterized by risk factors not reflected in conventional risk scores. In this context, little is known about the outcome of patients suffering from an active cancer disease (ACD). The objective was to determine the prevalence, clinical characteristics, perioperative outcomes, and mortality of patients with ACD undergoing TAVR compared to those with a history of cancer (HCD) and controls without known tumor disease...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is an alternative for surgically inoperable patients with severe aortic stenosis. Advanced kidney disease may significantly affect outcomes in patients treated with TAVR and surgical aortic valve replacement (SAVR). HYPOTHESIS: TAVR is associated with better in-hospital outcomes compared with SAVR in patients with advanced kidney disease. METHODS: We identified our sample from the National Inpatient Sample between 2012 and 2014, using International Classification of Diseases, Ninth Revision, Clinical Modification codes...

BACKGROUND: Although transvenous right ventricular (RV) endocardial lead placement is routine practice in clinical pacing, RV inaccessibility in certain clinical situations mandates the search for other sites. HYPOTHESIS: This study is aimed to verify whether left ventricular lead through coronary sinus is safe and efficient. METHODS: Based on a retrospective analysis of a single-center series of 4 patients with inaccessibility for RV pacing, we report on the feasibility and reliability of coronary sinus (CS) pacing via left ventricular (LV) lead, which usually is used in cardiac resynchronization therapy...

Dysregulated pathway identification is an important task which can gain insight into the underlying biological processes of disease. Current pathway-identification methods focus on a set of co-expression genes and single pathways and ignore the correlation between genes and pathways. The method proposed in this study, takes into account the internal correlations not only between genes but also pathways to identifying dysregulated pathways related to Alzheimer's disease (AD), the most common form of dementia...

BACKGROUND: Bicuspid Aortic Valve (BAV) is the most common congenital heart disease, affecting >1% of the general population. Up to date, three genes, NOTCH1, GATA5 and SMAD6, have been linked to the isolated form of BAV. However, potential genetic determinants remain largely unknown in most BAV patients. MATERIAL AND METHODS: Targeted next-generation sequencing of 7 BAV candidate genes (NOTCH1, GATA5, SMAD6, NOS3, ADAMTS5, Alk2 and SMAD2) was performed in 32 BAV patients...

Posterior urethral valves (PUV) constitute a significant urological cause of chronic kidney disease (CKD) in children. The condition is characterised by the unique pathophysiology of the evolution of bladder dysfunction after relief of obstruction, which contributes to CKD. Improvements in prenatal diagnosis followed by selective foetal intervention have not yet produced improvement in long-term renal outcomes, although better patient selection may alter this in the future. Proactive management with surveillance, pharmacotherapy, timed voiding, double voiding, and/or assisted bladder-emptying, is being increasingly offered to those with severe bladder dysfunction and has the potential of reducing the burden of renal disease...

AIMS: Calcific aortic valve disease is the most common heart valve disease in the Western world. Bicuspid and tricuspid aortic valve calcifications are traditionally considered together although the dynamics of the disease progression is different between the two groups of patients. Notch signaling is critical for bicuspid valve development and NOTCH1 mutations are associated with bicuspid valve and calcification. We hypothesized that Notch-dependent mechanisms of valve mineralization might be different in the two groups...

Risk assessment for transcatheter aortic valve implantation (TAVI) patients remains challenging, especially in elderly and high-risk candidates. Although several risk factors contribute to increased morbidity and mortality after TAVI, simple risk scores for routine use are lacking. Applying the CHA2DS2-VASC (congestive heart failure, hypertension, age ≥ 75 years, diabetes, prior stroke, vascular disease, age 65-74 years, sex [female] category) score as a novel risk stratification tool for conditions other than atrial fibrillation and stroke prevention has been previously examined; however, its usefulness in a population of patients with aortic stenosis after TAVI has not been established...

In developed countries, calcific aortic stenosis (CAS) has become the most common acquired valvular disease and reason for aortic valve replacement. It is considered a form of atherosclerosis and, like the latter, of inflammatory origin, with presence in the calcified aortic valves of blood vessels, lymphatics, lymphocytes, plasma cells, histiocytes, and sometimes also of metaplastic bone tissue. This study is aimed at examining the presence of CD117 - positive mast cells in CAS. In 56 examined calcified aortic valves excised by cardiac surgery, mast cells were constantly present as a part of the polymorphous cellular infiltrate; in individual cases, their numbers were 1-90 (median 24)...

Tricuspid regurgitation (TR) is a common entity, most commonly functional in nature due to right-sided dysfunction in the setting of concomitant cardiac disease or pulmonary hypertension. Patients living with TR often experience numerous limitations as a result of right-sided heart failure symptoms, including functional decline, frequent hospitalizations, liver failure, and kidney failure. Furthermore, patients with significant TR demonstrate worse survival, although a cause-and-effect relationship has not been proven...

Recently, transcatheter therapy has expanded the treatment options for patients with heart valve disease. With the growing understanding of tricuspid regurgitation and its natural history, it becomes increasingly obvious that this patient population is a heterogeneous cohort presenting for treatment in different stages of a continuous disease process. It is still unclear which interventional approach will result in functional and clinical success and in which subtype of patient population. This article reviews the pathophysiologic background and current evidence for caval valve implantation and examines the potential role of this approach for the treatment of severe tricuspid regurgitation...

REVIEW

Significant tricuspid valve disease affects many patients with left-sided heart disease. Concomitant tricuspid valve surgery for at least moderate tricuspid insufficiency is undertaken far less frequently at the time of left-sided heart surgery. The burden of residual tricuspid disease in high-surgical-risk patients has spawned the evolution of several percutaneous treatment options. A dedicated percutaneously delivered tricuspid Spacer device (FORMA Repair System) has been developed and trialed in humans. This system anchors a Spacer to reduce the regurgitant orifice area, thereby providing a surface for valve leaflet coaptation...

A commonly heard concern in the Ross procedure, where a diseased aortic valve is replaced by the patient's own pulmonary valve, is the possibility of pulmonary autograft dilatation. We performed a biomechanical investigation of the use of a personalized external aortic root support or exostent as a possibility for supporting the autograft. In ten sheep a short length of pulmonary artery was interposed in the descending aorta, serving as a simplified version of the Ross procedure. In seven of these cases, the autograft was supported by an external mesh or so-called exostent...

We present the surgical implantation in mitral position of the Edwards Sapien 3 valve for prosthetic valve endocarditis in a severely ill child after multiple valve replacements. The procedure was safely performed and provided adequate hemodynamic results in the short term. This report highlights the excellent potential of Sapien 3 valve for the treatment of mitral valve disease in children with a mitral valve annulus of appropriate size. Of note, the use of the Sapien 3 valve should be considered when a bioprosthesis is required at the time of valve re-replacement...

Surgical aortic valve replacement (SAVR) in patients with porcelain aorta is considered a high-risk procedure. Hence, transcatheter aortic valve implantation (TAVI) is emerging as the intervention of choice. However, there is a paucity of data directly comparing TAVI with SAVR in patients with porcelain aorta. We compared outcomes of TAVI versus SAVR in high-risk patients with porcelain between March 2012 and June 2015. The TAVI group included 54 patients, whereas 130 SAVR patients with porcelain aorta were identified (operated on between 2004 and 2015)...

INTRODUCTION: Aortic stenosis is the most prevalent type of valvular disease in Europe. Surgical aortic valve replacement (SAVR) is the standard therapy, while transcatheter aortic valve implantation (TAVI) is an alternative in patients at unacceptably high surgical risk. Assessment by a heart team is recommended by the guidelines but there is little published evidence on this subject. The purpose of this paper is to describe the experience of a multidisciplinary TAVI program that began in 2008...

OBJECTIVES: The goal of this study was to explore sex differences in myocardial remodeling in aortic stenosis (AS) by using echocardiography, cardiac magnetic resonance (CMR), and biomarkers. BACKGROUND: AS is a disease of both valve and left ventricle (LV). Sex differences in LV remodeling are reported in AS and may play a role in disease phenotyping. METHODS: This study was a prospective assessment of patients awaiting surgical valve replacement for severe AS using echocardiography, the 6-min walking test, biomarkers (high-sensitivity troponin T and N-terminal pro-brain natriuretic peptide), and CMR with late gadolinium enhancement and extracellular volume fraction, which dichotomizes the myocardium into matrix and cell volumes...
