Transcatheter aortic valve replacement in the management of aortic insufficiency secondary to left ventricular assist device implantation: a case report.

Background: Left ventricular assist device (LVAD) is considered either a destination therapy for patients with end-stage heart failure or heart transplantation bridging. LVAD implantation often causes aortic insufficiency (AI), which requires aortic valve repair. However, severe acute AI does not respond well to medication, and re-operation means higher risk to the patients; the most effective therapeutic strategies for LVAD-induced AI still need further exploration.

Results of new-generation balloon vs. self-expandable transcatheter heart valves for bicuspid aortic valve stenosis.

Background: Data comparing new-generation self-expandable (SEV, Evolut R/PRO) vs. balloon-expandable (BEV, SAPIEN 3/3Ultra) transcatheter heart valve replacement (TAVR) in bicuspid aortic valve stenosis (BAV) is limited. Our aim was to compare 30-day results of SEV and BEV implantations in patients with BAV.

Bioprosthetic Valve Fracturing: Testing of Edwards PERIMOUNT Model P 2900.

Background: Bioprosthetic valve fracturing (BVF) results in low gradients following valve-in-valve transcatheter aortic valve replacement (ViV-TAVR). For the commonly used Edwards PERIMOUNT valve data from bench-testing are lacking to provide technical specifications for successful BVF during ViV-TAVR.

Methods: Using four Perimount 19- and 21-mm valves, high-pressure balloon valvuloplasty with the True Dilatation Balloon Valvuloplasty Catheter and Atlas Gold PTA Dilatation Catheter was performed to analyze balloon-oversizing and pressure-thresholds to successfully achieve BVF.

Possible proteomic biomarkers for the detection of pancreatic cancer in oral fluids.

The 80% mortality rate of pancreatic-cancer (PC) makes early diagnosis a challenge. Oral fluids (OF) may be considered the ultimate body fluid for non-invasive examinations. We have developed techniques to improve visualization of minor OF proteins thereby overcoming major barriers to using OF as a diagnostic fluid.

Comparison of Self-Expanding Bioprostheses for Transcatheter Aortic Valve Replacement in Patients With Symptomatic Severe Aortic Stenosis: SCOPE 2 Randomized Clinical Trial.

Background: Few randomized trials have compared bioprostheses for transcatheter aortic valve replacement, and no trials have compared bioprostheses with supra-annular design. The SCOPE 2 trial (Safety and Efficacy Comparison of Two TAVI Systems in a Prospective Randomized Evaluation 2) was designed to compare the clinical outcomes of the ACURATE neo and CoreValve Evolut bioprostheses for transcatheter aortic valve replacement.

Methods: SCOPE 2 was a randomized trial performed at 23 centers in 6 countries between April 2017 and April 2019.

Histological examination of explanted tissue-engineered bovine pericardium following heart valve repair.

Objectives: Our goal was to present histopathological findings of human explants of a tissue-engineered bovine pericardium CardioCel (Admedus Regen Pty Ltd, Malaga, WA, Australia) used for heart valve repair in patients with congenital and acquired heart valve disease.

Methods: Sixty patients underwent heart valve repair from May 2014 to November 2018 using CardioCel as a substitute for valve tissue. We identified 9 cases in which the CardioCel patch was explanted following valve repair and available for histomorphological analyses.

Proteomic profiling of whole-saliva reveals correlation between Burning Mouth Syndrome and the neurotrophin signaling pathway.

Burning mouth syndrome (BMS) is characterized by a spontaneous and chronic sensation of burning in the oral mucosa, with no apparent signs. The underlying pathophysiological and neuropathic mechanisms remain unclear. Here, we attempt to elucidate some of these mechanisms using proteomic profiling and bioinformatic analyses of whole-saliva (WS) from BMS patients compared to WS from healthy individuals.

Aortic annulus sizing in stenotic bicommissural non-raphe-type bicuspid aortic valves: reconstructing a three-dimensional structure using only two hinge points.

Bicuspid aortic valve (BAV) anatomy is becoming an increasingly frequently encountered challenge in transcatheter aortic valve implantation (TAVI). Bicommissural non-raphe-type BAV (Sievers and Schmidtke Type 0) is composed morphologically of two aortic cusps with no raphe and is less common than the tricommissural or bicommissural raphe-type configurations. Precise annular sizing is a key step for successful TAVI in BAV.

Identification of salivary protein biomarkers for orthodontically induced inflammatory root resorption.

Methods:  A total of 11,496 patients with isolated coronary artery bypass grafting (CABG), operated between January 1996 and December 2012, were analyzed retrospectively; 0.

High-Risk Cardiac Surgery in Patients with Intravenous Drug Abuse and/or Active Hepatitis C or HIV Infection: An Ethical Discussion of Six Cases.

Objectives: To discuss the dilemma of adequate decision making in patients with intravenous drug abuse and recurrent valve prosthesis infections or in patients with positive HIV or hepatitis C status. Ethical, social, and economic considerations, not only in terms of technical feasibility but also in terms of unpromising results and aspects of resources, are discussed. Thoughts are presented about the legitimation of cardiac surgery centers refusing to perform surgery in high-risk patients with HIV or hepatitis C infections.

Aortic Dissections Type A during Sexual Intercourse in Male Patients: Accident or Systematic Coincidence? Examination of 365 Patients with Acute Aortic Dissection within 20 Years.

Objectives: Physical exercise accompanied by arterial hypertension is known to trigger acute aortic dissections. As a booster effect, mental stress leads to aggravation of hypertensive crisis. The aim of the study was to evaluate whether stress factors during sexual intercourse play any role as a catalyst in patients with acute type A aortic dissections.

Identification of Sjögren's syndrome oral fluid biomarker candidates following high-abundance protein depletion.

Objective: SS is an autoimmune exocrinopathy affecting ∼1 million patients in the USA that is diagnosed mostly in middle-aged women. Oral fluids (OFs) serving as the mirror of the body were suggested as an ideal non-invasive diagnostic tool. Previously we developed depletion techniques for OF high-abundance proteins to increase visualization of low-abundance proteins.

Novel thoughts on patient-prosthesis mismatch in aortic valve replacement: the rationale for the PAR I trial.

The hemodynamic performance of prosthetic tissue valves is influenced by valve design and valve-specific sizing strategies. Design determines the actual geometric opening area (GOA) of the prosthetic valve and sizing strategy its actual chosen size. Currently, hemodynamic performance is assessed by determining the effective orifice area (EOA; derived from the continuity equation by relating flow velocities with the area of the left ventricular outflow tract [LVOTA]).

Applying the Gender Lens to Risk Factors and Outcome after Adult Cardiac Surgery.

Background: Applying the gender lens to risk factors and outcome after adult cardiac surgery is of major clinical interest, as the inclusion of sex and gender in research design and analysis may guarantee more comprehensive cardiovascular science and may consecutively result in a more effective surgical treatment as well as cost savings in cardiac surgery.

Methods: We have reviewed classical cardiovascular risk factors (diabetes, arterial hypertension, hyperlipidemia, smoking) according to a gender-based approach. Furthermore, we have examined comorbidities such as depression, renal insufficiency, and hormonal influences in regard to gender.

[Screening saliva].

Oral Fluids (OF) are a complex mixture including components deriving from, salivary glands, blood, nasal and bronchial secretions, mucosal lining cells and microbiota. Therefore, OF as a mirror of the body, were suggested as an important diagnostic fluid for the detection of both, oral and systemic diseases. OF as diagnostic fluids have several advantages; their collection is easy, inexpensive and noninvasive, they are suitable for home use and for epidemiology researches, they are easy to store and ship, do not clot and enable fast detection.
