Transcatheter aortic valve replacement-in-transcatheter aortic valve replacement for high-risk anatomies: demonstrating the feasibility of index leaflet overhang in a first-in-human case report.

Background: Transcatheter aortic valve replacement (TAVR)-in-TAVR within index supra-annular transcatheter heart valves (THVs) and high-risk anatomy can compromise coronary perfusion and re-access.

Case Summary: An 80-year-old male presented with acute heart failure caused by degeneration of an Evolut R THV, leading to severe aortic regurgitation. Aortic computed tomography imaging revealed a high-risk anatomy characterized by the index THV's commissural plane being placed above the coronary ostia and a valve-to-aorta distance of less than 2 mm, resulting not eligible for redo-TAVR according to recent literature.

Clinical outcomes of patients with bicuspid aortic valve undergoing a targeted transcatheter aortic valve replacement approach: the LIRA Method.

Background: Transcatheter aortic valve replacement (TAVR) in patients with bicuspid aortic valve (BAV) disease is still burdened by a non-negligible rate of stroke and permanent pacemaker implantation (PPI). These suboptimal results, possibly related to the unique BAV anatomy, might suggest the use of a different sizing method in this setting. The aim of our study is to evaluate whether the application of the supra-annular LIRA method might improve clinical outcomes in this population.

Ranolazine Unveiled: Rediscovering an Old Solution in a New Light.

Ranolazine is an anti-anginal medication that has demonstrated antiarrhythmic properties by inhibiting both late sodium and potassium currents. Studies have shown promising results for ranolazine in treating both atrial fibrillation and ventricular arrhythmias, particularly when used in combination with other medications. This review explores ranolazine's mechanisms of action and its potential role in cardiac arrhythmias treatment in light of previous clinical studies.

MI2AMI-CS: A meta-analysis comparing Impella and IABP outcomes in Acute Myocardial Infarction-related Cardiogenic Shock.

Background: Cardiogenic Shock (CS) complicating acute myocardial infarction (AMI) poses a significant mortality risk, suggesting the opportunity to implement effective mechanical circulatory support strategies. The comparative efficacy of Intra-Aortic Balloon Pump (IABP) and Impella in managing CS-AMI remains a subject of investigation.

Objective: This meta-analysis aims to evaluate the comparative effectiveness of Impella and IABP in managing CS-AMI, exploring mortality and adverse events.

Chest Pain and the Dynamic Evolution of Spontaneous Coronary Artery Hematoma.

Spontaneous coronary intramural hematoma (SCIH) is a rare but underdiagnosed condition, with dynamic evolution. We present a patient with acute chest pain and normal coronary angiogram undergoing work-up for myocardial infarction with nonobstructive coronary arteries. Cardiac magnetic resonance revealed an ischemic pattern, and subsequent angiography revealed coronary occlusion by SCIH.

Gliflozins: From Antidiabetic Drugs to Cornerstone in Heart Failure Therapy-A Boost to Their Utilization and Multidisciplinary Approach in the Management of Heart Failure.

Heart failure (HF) is a complex, multifactorial, progressive clinical condition affecting 64.3 million people worldwide, with a strong impact in terms of morbidity, mortality and public health costs. In the last 50 years, along with a better understanding of HF physiopathology and in agreement with the four main models of HF, many therapeutic options have been developed.
