BACKGROUND: Transcatheter aortic valve replacement (TAVR) is the method of choice for patients with severe aortic valve stenosis, who are ineligible or at high risk for surgery. Though TAVR leads to a significant reduction in mortality, a notable amount of patients are re-hospitalized early after TAVR. Parameters or biomarkers predicting outcome are therefore needed to identify patients who benefit most. Specific monocyte subsets have been associated with cardiovascular diseases and were shown to possess prognostic value...

OBJECTIVE: The purpose of this work is to analyze the clinical results of treating severe mitral stenosis (MS) with mild to moderate functional tricuspid regurgitation (FTR) with mitral valve replacement (MVR) alone or together with two different methods of tricuspid valvuloplasty (TVP). PATIENTS AND METHODS: We split 132 patients into three groups: simple MVR with 47 cases (control group), MVR+ TVP (De Vega loop reduction) with 45 cases (observation group 1) and MVR+ TVP (Edwards MC3 tricuspid forming ring implantation) with 40 cases (observation group 2)...

Calcific aortic stenosis (AS) is one of the most common acquired valvular heart diseases in industrialized nations. It is a slowly progressive disease and with the aging population, the prevalence of AS is expected to increase. Doppler echocardiography is used to classify patients based on severity of stenosis. Research efforts on how to better identify and risk-assess these patients are currently underway using advanced imaging modalities and serum biomarkers. Thus far, medications for AS prevention have been unsuccessful...

BACKGROUND: Previous studies into the effect of a reduced left ventricular ejection fraction (EF) on the short- and long-term prognosis of patients undergoing transcatheter aortic valve implantation (TAVI) have reported conflicting findings. We analysed data from the Karlsruhe TAVI registry with the aim of addressing this question. METHODS AND RESULTS: Patients with aortic stenosis undergoing TAVI were divided into sub-groups according to EF: severely reduced (<30%; n = 109), reduced (≥30 and ≤40%; n = 201), and mid-range/preserved (>40%; n = 1690)...

Echocardiography is the cornerstone in the diagnosis of any valvular heart disease. The accurate diagnosis of aortic stenosis, the left ventricle function and the other heart valves evaluation are currently done by ultrasound alone. Prosthetic valve choice and dimensions prior to implantation can be done solely by proper use of echocardiography. The emergence of new methods to cure aortic stenosis such as trans-catheter aortic valve replacement (TAVR) emphasized the diagnostic value of cardiac ultrasound. The usefulness of echocardiography in TAVR can be divided in the baseline assessment (common to patients treated by conventional surgery), intra-procedural guidance of valve deployment and post-procedural follow-up...

We report the use of three-dimensional (3D) modeling to plan surgery for physiologic repair of congenitally corrected transposition of the great arteries with pulmonary atresia, dextrocardia, and complex intra cardiac anatomy. Based on measurements made from the 3D printed model of the actual patient's anatomy, we anticipated using a composite valved conduit (Dacron tube graft, decellularized bovine jugular vein, and aortic homograft) to establish left ventricle-to-pulmonary artery continuity with relief of stenosis involving the pulmonary artery confluence and bilateral branch pulmonary arteries...

A 67-year-old woman with recurrent gastrointestinal bleeding and aortic valve stenosis presented with spurting bleeding from angiodysplasia of the upper jejunum. As electrophoresis revealed decreased levels of high-molecular-weight (HMW) von Willebrand factor (VWF) multimers, she was diagnosed with Heyde's syndrome. After aortic valve replacement, her HMW VWF levels quickly recovered to normal, and the gastrointestinal bleeding ceased. However, capsule endoscopy still revealed gastrointestinal angiodysplasia six months later...

Electrocardiographic (ECG) strain has been reported as a specific marker of midwall left ventricular (LV) myocardial fibrosis, predictive of adverse clinical outcomes in aortic stenosis (AS), but its prognostic impact after aortic valve replacement (AVR) is unknown. We aimed to assess the impact of ECG strain on long-term mortality after surgical AVR for AS. From January 2005 to January 2014, patients with interpretable preoperative ECG who underwent isolated AVR for AS were included. ECG strain was defined as ≥1-mm concave downslopping ST-segment depression with asymmetrical T-wave inversion in lateral leads...

This review summaries the utility, application and data supporting use of cardiac magnetic resonance imaging (CMR) to evaluate and quantitate aortic regurgitation. We systematically searched Medline and PubMed for original research articles published since 2000 that provided data on the quantitation of aortic regurgitation by CMR and identified 11 articles for review. Direct aortic measurements using phase contrast allow quantitation of volumetric flow across the aortic valve and are highly reproducible and accurate compared with echocardiography...

BACKGROUND: Left ventricular (LV) filling following atrial contraction generates LV myocardial stretch that propagates from base to apex with a speed proportional to myocardial elasticity. The aim of this study was to test the hypothesis that intrinsic velocity propagation of myocardial stretch (iVP) would be altered in patients with valvular disease and chronic LV pressure overload or volume overload, which may adversely affect mechanical properties of the LV tissue. A second aim was to compare iVP with flow propagation velocity in the chamber...

BACKGROUND: Transcatheter aortic valve replacement entails profound and unavoidable hemodynamic perturbations that may contribute to the neurological injury associated with the procedure. METHODS: Thirty-one patients were monitored with cerebral oximetry as a surrogate marker of perfusion while undergoing transcatheter aortic valve replacement via a transfemoral approach under general anesthesia to detect intraoperative hypoperfusion insult. Serial neurologic, cognitive, and cerebral magnetic resonance imaging assessments were administered to objectively quantify perioperative neurologic injury and ascertain any association with significant cerebral oximetry disturbances...

BACKGROUND: Previous studies suggest a relationship of the epicardial adipose tissue (EAT) with progression and calcification of the atherosclerotic plaque; however, it is unknown if this tissue expresses genes that may participate on these processes and if the expression of these genes is regulated by high-density lipoprotein (HDL) subclasses. METHODS: To explore this possibility, we determined the mRNA expression by qPCR of a pro-calcifying gene (osteopontin (OPN)), and two anti-calcifying genes (osteoprotegerin (OPG) and osteonectin (ON)), in biopsies of EAT obtained from 15 patients with coronary artery disease (CAD) determined by angiography, and 15 patients with diagnostic of aortic valve stenosis but without CAD as control group...

A 58-year-old man with a history of hypertension presented with accelerating angina. Transthoracic echocardiography revealed a thickened aortic valve with pressure gradients and an estimated aortic valve area suggestive of mild aortic stenosis. Left heart catheterization demonstrated non-significant coronary artery disease. Pressure tracings showed a high left ventricular pressure and a mean gradient across the aortic valve of 69 mmHg. Subsequent transesophageal echocardiography revealed a subvalvular aortic stenosis that was secondary to the subaortic membrane, with severe valvular aortic stenosis...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is an effective treatment for severe aortic stenosis in high-risk patients. Several complications related to the TAVI procedure, including aortic regurgitation (AR), cerebrovascular accident (CVA) and the requirement for permanent pacemaker (PPM), are thought to be secondary to balloon aortic valvuloplasty (BAV) before TAVI. The aim of the present review was to evaluate any beneficial role of the direct TAVI approach over BAVTAVI...
