Impact of lead position on tricuspid regurgitation, ventricular function, and heart failure exacerbation and mortality after cardiac implantable electronic device implantation. Preliminary results from the PACE-RVTR Registry.

Background: The most frequent mechanism of lead-related tricuspid regurgitation (LRTR), which occurs in 7.2% to 44.7% of patients implanted with a cardiac implantable electronic device (CIED), is leaflet impingement or the restriction of its movement by a ventricular lead.

Echocardiographic predictors of positive left ventricular remodeling in patients with a history of active myocarditis.

Introduction: Myocarditis may be difficult to diagnose because of the variety of its clinical manifestations, and the clinical course of the disease can be unpredictable. Nevertheless, some patients may exhibit partial or full contractile recovery following myocarditis. Standard and speckle-tracking echocardiography may serve as tools to follow this recovery.

Update of Potential Biomarkers in Risk Prediction and Monitoring of Atherosclerosis in Systemic Lupus Erythematosus to Prevent Cardiovascular Disease.

Systemic lupus erythematosus is a chronic connective tissue disease associated with an increased risk of premature atherosclerosis. It is estimated that approximately 10% of SLE patients develop significant atherosclerosis each year, which is responsible for premature cardiovascular disease that is largely asymptomatic. This review summarizes the most recent reports from the past few years on biomarkers of atherosclerosis in SLE, mainly focusing on immune markers.

Lead-related tricuspid regurgitation and ventricle dysfunction: Current management and future perspectives.

The implantation of cardiac implantable electronic devices (CIEDs) may result in or worsen previously existing tricuspid regurgitation (TR). The prevelence of lead-related tricuspid regurgitation (LRTR) in patients with CIEDs is between 7.2% and 44.

Management of valvular heart disease in patients with cancer: Multidisciplinary team, cancer-therapy related cardiotoxicity, diagnosis, transcatheter intervention, and cardiac surgery. Expert opinion of the Association on Valvular Heart Disease, Association of Cardiovascular Interventions, and Working Group on Cardiac Surgery of the Polish Cardiac Society.

The Association on Valvular Heart Disease, Association of Cardiovascular Interventions, and the Working Group on CardiacSurgery of the Polish Cardiac Society have released a position statement on risk factors, diagnosis, and management of patients with cancer and valvular heart disease (VHD). VHD can occur in patients with cancer in several ways, for example, it can exist or be diagnosed before cancer treatment, after cancer treatment, be an incidental finding during imaging tests, endocarditis related to immunosuppression, prolonged intravenous catheter use, or combination treatment, and nonbacterial thrombotic endocarditis. It is recommended to employ close cardiac surveillance for patients at high risk of complications during and after cancer treatment and for cancer treatments that may be cardiotoxic to be discussed by a multidisciplinary team.

Graphene Oxide as a Collagen Modifier of Amniotic Membrane and Burnt Skin.

Introduction: The aim of this interdisciplinary study was to answer the question of whether active antioxidants as graphene oxide (GO), sodium ascorbate, and L-ascorbic acid modify at a molecular and supramolecular level the tissue of pathological amnion and the necrotic eschar degraded in thermal burn. We propose new solutions of modifiers based on GO that will become innovative ingredients to be used in transplants (amnion) and enhance regeneration of epidermis degraded in thermal burn.

Methods: A Nicolet 6700 spectrophotometer with Omnic software and the EasiDiff diffusion accessory were used in FTIR spectroscopic analysis.

The association of mechanical dyssynchrony and resynchronization therapy with survival in heart failure with a wide QRS complex: a two-world study.

Setting up a randomized trial to assess the association of mechanical dyssynchrony (MD) and the success of cardiac resynchronization therapy (CRT) in heart failure with a wide QRS complex is ethically challenging. We therefore investigated this association in a retrospective cohort study observing different treatment strategies which were chosen based on the availability of health care resources. The survival of 500 patients from six Western European centers treated with CRT was compared to their 137 Eastern European counterparts not treated with CRT, with regard to the presence of MD.

The impact of the aortic cusps fusion pattern and valve disease severity on the aortic wall mechanics in patients with bicuspid aortic valve.

The ascending aorta dilatation in the bicuspid aortic valve (BAV) patients is often attributed to congenital abnormalities of the aortic wall, but it may be related to hemodynamic disturbances in the course of BAV disease. At present, ascending aortic diameter is used as almost sole but weak predictor of aortic dissection and rupture in BAV. We examined the association between aortic wall mechanics and severity of aortic valve disease including different cusps fusion patterns using conventional echocardiography and tissue Doppler imaging (TDI).

Comparison of transesophageal and intracardiac echocardiography in guiding percutaneous left atrial appendage closure with an Amplatzer Amulet device.

Introduction: Percutaneous occlusion of the left atrial appendage (LAAO) is becoming an extensively used method of stroke prevention in individuals with contraindications to oral anticoagulants. Transesophageal echocardiography (TOE) is the gold standard for LAAO guiding, but intracardiac echocardiography (ICE) appears to be a potential alternative.

Aim: To compare the LAAO procedure guided by TOE or ICE with respect to procedural success and safety.
