Transcatheter mitral valve implantation in severe mitral annular calcification: a case report.

Background: Mitral annular calcification (MAC) is characterized by severe calcification of mitral annulus and might be associated with both mitral regurgitation and stenosis. It is technically challenging for both surgical and percutaneous approach and is burdened by high mortality.

Case Summary: The present case report describes a complex case of mitral steno-insufficiency (baseline transvalvular gradient = 5 mmHg, effective regurgitant orifice area 0.

Holographic mixed reality for planning transcatheter aortic valve replacement.

Background: Using three-dimensional (3D) modalities for optimal pre-procedure planning in transcatheter aortic valve replacement (TAVR) is critical for procedural success. However, current methods rely on visualizing images on a two-dimensional screen, using shading and colors to create the illusion of 3D, potentially impeding the accurate comprehension of the actual anatomy structures. In contrast, a new Mixed Reality (MxR) based software enables accurate 3D visualization, imaging manipulation, and quantification of measurements.

Immunomodulation Therapies for Atherosclerosis: The Past, the Present, and the Future.

Atherosclerotic cardiovascular disease is the most common cause of morbidity and death worldwide. Recent studies have demonstrated that this chronic inflammatory disease of the arterial wall can be controlled through the modulation of immune system activity. Many patients with cardiovascular disease remain at elevated risk of recurrent events despite receiving current, state-of-the-art preventive medical treatment.

Intermittent Normal Ventricular Conduction in Left Bundle Branch Block After TAVR.

In a patient who previously developed left bundle branch block after transcatheter aortic valve replacement, intermittent narrow QRS complexes were recorded on ambulatory electrocardiography monitoring. The peculiar distribution of wide and narrow QRS complexes suggested the presence of a window of supernormality in the refractory period of a branch block that on other occasions exhibited the Wenckebach phenomenon.

Treatment with gentamicin-impregnated collagen sponges in reducing infection of implantable cardiac devices: 10-year analysis with propensity score matching.

Introduction And Objectives: The incidence of device infection has increased over time and is associated with increased mortality in patients with cardiac implantable electronic devices (CIEDs). Gentamicin-impregnated collagen sponges (GICSs) are useful in preventing surgical site infection (SSI) in cardiac surgery. Nevertheless, to date, there is no evidence concerning their use in CIED procedures.

Successful percutaneous catheter-directed treatment of high-risk pulmonary embolism: a case report.

Background: Pulmonary embolism (PE) is an acute cardiovascular syndrome characterized by high incidence and mortality. The therapy of this condition is based on anticoagulation and hemodynamic support, but in case of high-risk mortality, the European Society of Cardiology (ESC) guidelines recommend systemic thrombolytic therapy and surgical embolectomy if thrombolysis is contraindicated or has failed; nowadays several percutaneous catheter-directed treatments for local thrombolysis or mechanical embolectomy are available, but they have IIa class of recommendation, because of lack of robust scientific evidence favoring their use.

Case Description: We described a case of high-risk PE treated with a novel percutaneous system for mechanical embolectomy, which consists of a large aspiration catheter that was advanced in the pulmonary artery, capturing and removing a vast thrombus, of 15 centimeters in length.

Rationale and design of the sirolimus eluting balloon utilization for treatment of vasculogenic erectile dysfunction: the SUASION Registry.

Background: Conventional angioplasty balloon catheter, drug coated balloon (DCB), or angioplasty with drug eluting stent (DES) have been used on the percutaneous treatment of erectile dysfunction (ED). Currently available DCBs are paclitaxel eluting balloon (PEB), very recently, sirolimus eluting balloon (SEB). Although endovascular revascularization with balloon resulted in improvement of ED, there have been no prior reports on the feasibility of SEB treatment for ED.

Acute effect of edge-to-edge repair of mitral regurgitation on left heart mechanics and health status.

Aims: Examine the impact of acute changes in left heart strain and volumes with percutaneous edge-to-edge MitraClip repair on improvement in health status assessed using Kansas City Cardiomyopathy Questionnaire-12 (KCCQ-12) score.

Methods: Changes in left atrial strain, left ventricular (LV) global longitudinal strain (LVGLS), LV end-systolic volume (LVESV), and end-diastolic volume (LVEDV) were evaluated in 50 patients undergoing MitraClip repair for symptomatic primary mitral regurgitation (PMR) and secondary mitral regurgitation (SMR) on transthoracic echocardiography before and 1 month after MitraClip. Multivariable regression was used to evaluate changes in left heart strain and volumes as predictors of change in KCCQ-12 scores, adjusting for baseline clinical and echocardiographic characteristics.

The Transaxillary Route as a Second Access Option in TAVI Procedures: Experience of a Single Centre.

The aim of our study was to determine the feasibility and efficacy of transaxillary (TAX) TAVI in patients not eligible for the transfemoral route. This is a retrospective study of a single center. We analysed 262 patients treated with TAVI.

Autologous Immune Cell-Based Regenerative Therapies to Treat Vasculogenic Erectile Dysfunction: Is the Immuno-Centric Revolution Ready for the Prime Time?

About 35% of patients affected by erectile dysfunction (ED) do not respond to oral phosphodiesterase-5 inhibitors (PDE5i) and more severe vasculogenic refractory ED affects diabetic patients. Innovative approaches, such as regenerative therapies, including stem cell therapy (SCT) and platelet-rich plasma (PRP), are currently under investigation. Recent data point out that the regenerative capacity of stem cells is strongly influenced by local immune responses, with macrophages playing a pivotal role in the injury response and as a coordinator of tissue regeneration, suggesting that control of the immune response could be an appealing approach in regenerative medicine.

Serum uric acid in patients with ST-segment elevation myocardial infarction: An innocent bystander or leading actor?

Elevated serum uric acid (SUA) levels have been associated with several cardiovascular risk factors and the progression of coronary artery disease. In the setting of acute myocardial infarction, increasing evidence suggests that high SUA levels could be related to adverse outcomes. Interestingly elevated SUA levels have been linked to endothelial dysfunction, inflammation and oxidative stress.

Challenges and Open Issues in Transcatheter Mitral Valve Implantation: Smooth Seas Do Not Make Skillful Sailors.

According to the European and American guidelines, surgery represents the treatment of choice for mitral valve (MV) disease. However, a number of patients are deemed unsuitable for surgery due to a prohibitive/high operative risk. In such cases, transcatheter therapies aiming at MV repair have been proven to be a valuable alternative and have been recently introduced in the latest American guidelines on valvular heart disease.

Clinical Features and Management of COVID-19-Associated Hypercoagulability.

COVID-19 is an acute respiratory disease of viral origin caused by SARS-CoV-2. This disease is associated with a hypercoagulable state resulting in arterial and venous thrombotic events. The latter are more frequent, especially in patients who develop a severe form of the disease and are associated with an increased mortality rate.

Unequal opportunities in Italian cardiovascular research: focus on gender.

Background: Despite unanimous calls for more equitable access and support to female researchers, there are persistent barriers to women's career progression and professional fulfillment. These discriminative hurdles undermine female gender in science and have detrimental effects on research activities and female professionals and patients. There is no data on women's outlook in cardiovascular research in Italy, which limits appropriate remedial actions.

Cardiovascular medicine: a year in review.

Cardiovascular medicine is facing several challenges in the current era, dominated by the rapid spread of a previously unknown virus around the world. Indeed, the 2020 COVID-19 pandemic set the course of cardiovascular science and education in an extraordinary way, hogging the attention of the medical community. Notably, while COVID-19 impacted research progress, there has been considerable effort in exploring topics of great interest, from the management of acute coronary syndromes to new horizons in the treatment of heart failure, from novelties in the surgical treatment of cardiovascular disease to new data on implantable cardiac devices, and from new diagnostic applications of multimodal imaging techniques to relevant basic science findings.

A thymic hyperplasia-related reversible complete atrioventricular block: When compression is more important than compressor.

A 19-year-old patient presented for syncope with third-degree AV block (TDAVB) at ECG. A chest-CT showed a thymic mass that could be responsible for TDAVB due to extrinsic vagal nerve compression. Thymectomy led to complete AV block resolution.

Home Management of Heart Failure and Arrhythmias in Patients with Cardiac Devices during Pandemic.

Background: The in-hospital management of patients with cardiac implantable electronic devices (CIEDs) changed early in the COVID-19 pandemic. Routine in-hospital controls of CIEDs were converted into remote home monitoring (HM). The aim of our study was to investigate the impact of the lockdown period on CIEDs patients and its influence on in-hospital admissions through the analysis of HM data.

Electrocardiographic modifications and cardiac involvement in COVID-19 patients: results from an Italian cohort.

Aim: The aim of this study was to detect predisposing CV risks factors and ECGs changes in COVID-19 patients.

Methods: The study population included 60 noncritically ill patients with COVID-19 pneumonia admitted to our hospital between 16 March and 11 May 2020. Electrographic changes, evaluated from ECGs acquired at admission and at 7 days after starting COVID-19 therapy, were analysed.

MiR-423 is differentially expressed in patients with stable and unstable coronary artery disease: A pilot study.

Coronary artery disease (CAD) and acute myocardial infarction (AMI) are the leading causes of death worldwide. Since only a subset of CAD patients develops myocardial infarction, it is likely that unique factors predispose to AMI. Circulating microRNAs represent diagnostic powerful biomarkers for detection of heart injuries and patients' risk stratification.

Inflammasome, T Lymphocytes and Innate-Adaptive Immunity Crosstalk: Role in Cardiovascular Disease and Therapeutic Perspectives.

Over the past few decades, lot of evidences have shown atherosclerosis as a chronic progressive disease with an exquisite inflammatory feature. More recently, the role of innate immune response in the onset and progression of coronary artery disease (CAD) and an adaptive immunity imbalance, mostly involving T cell sub-sets, have been documented. Therefore, like in many other inflammatory and autoimmune disorders, an altered innate-adaptive immunity crosstalk could represent the key of the inflammatory burden leading to atherosclerotic plaque formation and progression and to the breakdown of plaque stability.

Carotid Doppler sonography: additional tool to assess hemodynamic improvement after transcatheter aortic valve implantation.

Purpose: The aim of our study was to assess the arterial cerebral blood flow variations in patients with aortic valve stenosis, immediately after the transcatheter aortic valve implantation (TAVI).

Methods: The study population includes 62 consecutive patients who underwent TAVI for aortic valve stenosis (95%) and sugical bioprosthesis degeneration (5%). Carotid Doppler examination was performed recording blood flow, systolic peak velocity, time average mean velocity and mean acceleration time at baseline, after balloon aortic valvuloplasty, and within 10 min after the device release.
