Types of Transcatheter Aortic Valve Replacement Devices
Transcatheter aortic valve replacement (TAVR) was originally conceptualized in the early 1990s, largely inspired by the pioneering experiences in the field of percutaneous transluminal coronary angioplasty.

Immune Response to SARS-CoV-2 and mRNA Vaccines
The SARS-CoV-2 (severe acute respiratory syndrome coronavirus responsible for the COVID-19 disease) uses the Spike proteins of its envelope for infecting target cells expressing on the membrane the angiotensin converting enzyme 2 (ACE2) enzyme that acts as a receptor. To control the pandemic, genetically engineered vaccines have been designed for inducing neutralizing antibodies against the Spike proteins. These vaccines do not act like traditional protein-based vaccines, as they deliver the message in the form of mRNA or DNA to host cells that then produce and expose the Spike protein on the membrane (from which it can be shed in soluble form) to alert the immune system. Since the genetically engineered vaccines have been modified to be more stable and because they are distributed via liponanoparticles to various tissues and organs, this type of products may cause unforeseen serious adverse effects.

Folic Acid, Vitamin B12 and Chronic Kidney Disease
Patients affected by chronic kidney disease (CKD) or end-stage renal disease (ESRD) experience a huge cardiovascular risk and cardiovascular events represent the leading causes of death. Folic acid and vitamin B12 could not only be mere cofactors in the homocysteine metabolism; they may have a direct action in determining tissue damage and cardiovascular risk.

Blood Pressure Sensors
In our unique transdisciplinary approach, we studied the fundamentals of blood pressure and examined its measuring modalities while focusing on their clinical use and sensing principles to identify material functionalities. Then, we carefully reviewed various categories of functional materials utilized in sensor building blocks allowing for comparative analysis of the performance of a wide range of materials throughout the sensor operational-life cycle. Not only this provides essential data to enhance the materials’ properties and optimize their performance, but also, it highlights new perspectives and provides suggestions to develop the next generation pressure sensors for clinical use.

Tricuspid Atresia
Tricuspid atresia (TA) is a cyanotic, congenital heart defect (CHD) and is defined as congenital absence or agenesis of the morphologic tricuspid valve. It is the third most common cyanotic CHD, and is the most common cause of cyanosis with left ventricular hypertrophy. The prevalence of TA is estimated to be 2.9% of autopsy cases and 1.4% to 1.5% of the clinical cases of CHD.

Thyroid and Heart
The thyroid–heart relationship has a long and articulated history of its own, a history that encompasses physiological and pathophysiological knowledge. Molecular biology studies, in an experimental context, have highlighted the extraordinary dialogue that exists among the two systems in the field of cardioprotection, which is an extremely important area for the treatment of cardiac diseases in both acute and chronic phases. In addition, in the last few years, several studies have been carried out on the prognostic impact of alterations in thyroid function, including subclinical ones, in heart disease, in particular in heart failure and acute myocardial infarction, with evidence of a negative prognostic impact of these and, therefore, with the suggestion to treat these alterations in order to prevent cardiac events, such as death.  A comprehensive summary of the heart–thyroid relationship is provided.

Hypobaric Hypoxia and Heart
Under hypobaric hypoxia contidition, the principal impact on humans is due to the low atmospheric pressure  and the subsequent proportional decrease in partial oxygen pressure (PO2)  in the inspired air, generating a reduction in the bioavailability of oxygen in organs, tissues and cells at high altitude.

Heart Rate Variability in Irritable Bowel Syndrome
Heart Rate Variability (HRV) is a non-invasive biomarker that can measure autonomic tone. Autonomic Nervous System deregulation is considered the leading cause of Irritable Bowel Syndrome (IBS), which is associated with decreased parasympathetic tone. HRV can measure the parasympathetic tone and changes in autonomic tone caused by therapeutic intervention in IBS. Further research is needed to confirm the efficacy of using HRV to measure the effectiveness of therapeutic interventions in IBS.

Statins in High Cardiovascular Risk Patients
Atherosclerotic cardiovascular disease (ASCVD) morbidity and mortality are decreasing in high-income countries, but ASCVD remains the leading cause of morbidity and mortality in high-income countries. Over the past few decades, major risk factors for ASCVD, including LDL cholesterol (LDL-C), have been identified. Statins are the drug of choice for patients at increased risk of ASCVD and remain one of the most commonly used and effective drugs for reducing LDL cholesterol and the risk of mortality and coronary artery disease in high-risk groups. Unfortunately, doctors tend to under-prescribe or under-dose these drugs, mostly out of fear of side effects. The latest guidelines emphasize that treatment intensity should increase with increasing cardiovascular risk and that the decision to initiate intervention remains a matter of individual consideration and shared decision-making.
