Although it is believed that implementation of the functional generated path (FGP) technique can facilitate occlusal surface design for restorations, it has not been objectively compared in situ with the conventional fabrication yet. Therefore, in the present study, a single-blind crossover clinical trial was conducted using T-scan to compare changes in occlusion time (OT) and disocclusion time (DT) of single posterior artificial crowns designed differently using FGP technique (FGP), average-value FGP technique (AVR) and conventional fabrication (CON)...

Redo aortic valve replacement (AVR) performed simultaneously with left ventricular assist device (LVAD) implantation carries potential for increased mortality rates. Although transcatheter AVR has been used for patients with previous LVAD placement, no literature reports concomitant valve-in-valve transcatheter AVR and LVAD implantation. Our patient had severe aortic prosthetic valve deterioration and advanced heart failure. Given the risks associated with reoperative aortic valve surgery, we chose transcatheter AVR at the time of LVAD implantation...

BACKGROUND AND AIMS: Elevated levels of lipoprotein(a) [Lp(a)] and oxidized phospholipids on apolipoprotein B-100 (OxPL-apoB) predict the progression of pre-existing mild-to-moderate calcific aortic valve stenosis (CAVS). Whether indirect markers of oxidation-specific epitopes (OSE) are also predictive is not known. The association between IgG and IgM autoantibodies and malondialdehyde-modified low density lipoprotein (MDA-LDL) and IgG and IgM apolipoprotein B immune complexes (apoB-IC), and the hemodynamic progression rate of CAVS was determined in the ASTRONOMER (Aortic Stenosis Progression Observation: Measuring Effects of Rosuvastatin, NCT00800800) trial...

BACKGROUND: Out-of-hospital cardiac arrest (OHCA) remains a major public health issue. Emergency coronary angiography and percutaneous coronary intervention might improve survival, especially when cardiac arrest is caused by acute myocardial infarction (AMI). However, identifying patients with AMI after OHCA remains challenging. The aim of this study was to determine the clinical and ECG criteria in OHCA that may help to identify better the patients with AMI. METHODS: Consecutive OHCA patients who underwent emergency coronary angiography in our centre between 2009 and 2013 were included in this retrospective single-centre observational study...

In dialysis patients, electrocardiogram (ECG) abnormalities are common. However, the associations between the T-wave of the lead aVR (aVRT) amplitude and cardiovascular (CV) events or total mortality are unknown. We performed a prospective, observational cohort study of prevalent hemodialysis patients (N = 474), followed for 4 years. Outcomes were composite CV events and all-cause mortality. Predictors were baseline aVRT and other ECG findings. ECG parameters were analyzed in three models: model 1, univariate; model 2, basic adjustments; and model 3, model 2 plus serum albumin, C-reactive protein level, and NT-proBNP...

The use of transcatheter aortic valve replacement (TAVR) as an acute treatment in severe decompensated bioprosthetic aortic valve disease is not well documented. We describe herein a unique case in which valve-in-valve (ViV) TAVR was successfully used as both an emergency salvage therapy and a bridge to definitive fourth reoperative aortic valve replacement (AVR) in a young patient with cardiogenic shock secondary to bioprosthetic aortic valve stenosis who was dependent on veno-arterial extracorporeal membrane oxygenation (VA-ECMO)...

BACKGROUND: The use of transcatheter aortic valve implantation (TAVI) following the introduction of Nitinol autoexpandable devices has spread rapidly during recent years. In addition, cardiac surgery has been revolutionized due to the use of Nitinol-based sutureless prostheses for aortic valve replacement (AVR). During the same period, however, permanent pacemaker (PPM) implantation has emerged as a frequent complication. The study aim was to identify the risk factors of PPM following the implantation of a Nitinol self-expanding prosthesis (for AVR or TAVI)...
