Maintenance therapy with a P2Y12 receptor inhibitor after cangrelor in patients with acute coronary syndrome. The ELECTRA-SIRIO 2 investigators' viewpoint.

According to the ESC guidelines, cangrelor may be considered in P2Y12-inhibitor-naïve acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI). The aim of this review is to summarize available evidence on the optimal maintenance therapy with P2Y12 receptor inhibitor after cangrelor. Transitioning from cangrelor to a thienopyridine, but not ticagrelor, can be associated with a drug-drug interaction (DDI); therefore, a ticagrelor loading dose (LD) can be given any time before, during, or at the end of a cangrelor infusion, while a LD of clopidogrel or prasugrel should be administered at the time the infusion of cangrelor ends or within 30 minutes before the end of infusion in the case of a LD of prasugrel.

Regional disparities in the management and outcomes of ST-elevation myocardial infarction: an Italian analysis focusing on time-dependent reperfusion networks and in-hospital logistics.

Background: Prompt reperfusion is critical for patients with ST-segment elevation myocardial infarction (STEMI) to improve outcomes. Yet, variability in regional healthcare delivery may influence treatment times and patient outcomes. We thus aimed at evaluating differences in management and outcomes of STEMI patients across Northern, Central, and Southern Italy, focusing on time-dependent reperfusion and in-hospital logistics.

Prolonged antithrombotic treatment after de-escalation of dual antiplatelet therapy in patients after acute coronary syndrome - which strategy should be applied? The ELECTRA-SIRIO 2 investigators standpoint.

De-escalation of dual antiplatelet (DAPT) intensity may be considered in patients with high risk of bleeding after acute coronary syndrome. Some high risk patients after de-escalation may require antithrombotic therapy prolonged over 12 months. With the current guideline recommended strategies, there are some doubts and uncertainties with respect to the transition period.

Impact of surgical aortic valve replacement and transcatheter aortic valve implantation on cardiovascular and cerebrovascular controls: A pilot study.

Surgical aortic valve replacement (SAVR) and transcatheter aortic valve implantation (TAVI) are options in severe aortic valve stenosis (AVS). Cardiovascular (CV) and cerebrovascular (CBV) control markers, derived from variability of heart period, systolic arterial pressure, mean cerebral blood velocity and mean arterial pressure, were acquired in 19 AVS patients (age: 76.8 ± 3.

Performance of the minimalistic hybrid approach algorithm versus other conventional algorithms in the percutaneous treatment of chronic total occlusions.

Background: The "Minimalistic Hybrid Approach" (MHA) has been proposed to reduce the invasiveness of chronic total occlusion (CTO) percutaneous coronary intervention (PCI).

Aims: This study aims to assess whether MHA may also reduce the utilization of PCI resources (devices, radiations, and contrast) by comparing it with other conventional algorithms.

Methods: We aimed to assess the impact of MHA on device, radiation, and contrast usage during CTO-PCI analyzing data from the Belgian Working Group on CTO (BWG-CTO) registry.

Secondary retensioning of a tether-based device for transapical transcatheter mitral valve implantation.

Objectives: Relevant paravalvular leakage (PVL) due to prosthesis dislodgement is a rare but potentially severe complication after transcatheter mitral valve implantation (TMVI). Due to the epicardial anchoring mechanism of the Tendyne® TMVI system, repositioning of the valve stent may be possible by retensioning of the tether. This multicentre study aimed to investigate the procedural and short-term safety as well as efficacy of retensioning manoeuvres.

Lumped-parameter model as a non-invasive tool to assess coronary blood flow in AAOCA patients.

Anomalous aortic origin of the coronary artery (AAOCA) is a rare disease associated with sudden cardiac death, usually related to physical effort in young people. Clinical routine tests fail to assess the ischemic risk, calling for novel diagnostic approaches. To this aim, some recent studies propose to assess the coronary blood flow (CBF) in AAOCA by computational simulations but they are limited by the use of data from literature retrieved from normal subjects.

Incidence, Predictors, and Prognostic Impact of New Permanent Pacemaker Implantation After TAVR With Self-Expanding Valves.

Objectives: The authors sought to evaluate the incidence, predictors, and outcomes of new permanent pacemaker implantation (PPI) after transcatheter aortic valve replacement (TAVR) with contemporary self-expanding valves (SEV).

Background: Need for PPI is frequent post-TAVR, but conflicting data exist on new-generation SEV and on the prognostic impact of PPI.

Methods: This study included 3,211 patients enrolled in the multicenter NEOPRO (A Multicenter Comparison of Acurate NEO Versus Evolut PRO Transcatheter Heart Valves) and NEOPRO-2 (A Multicenter Comparison of ACURATE NEO2 Versus Evolut PRO/PRO+ Transcatheter Heart Valves 2) registries (January 2012 to December 2021) who underwent transfemoral TAVR with SEV.

Morphological Changes of Anomalous Coronary Arteries From the Aorta During the Cardiac Cycle Assessed by IVUS in Resting Conditions.

Background: Anomalous aortic origin of coronary artery (AAOCA) with intramural segment is associated with risk of sudden cardiac death, probably related to a compressive mechanism exerted by the aorta. However, the intramural compression occurrence and magnitude during the cardiac cycle remain unknown. We hypothesized that (1) in end diastole, the intramural segment is narrower, more elliptic, and has greater resistance than extramural segment; (2) the intramural segment experiences a further compression in systole; and (3) morphometry and its systolic changes vary within different lumen cross-sections of the intramural segment.

A CT-based deep learning system for automatic assessment of aortic root morphology for TAVI planning.

Accurate planning of transcatheter aortic valve implantation (TAVI) is important to minimize complications, and it requires anatomic evaluation of the aortic root (AR), commonly performed through 3D computed tomography (CT) image analysis. Currently, there is no standard automated solution for this process. Two convolutional neural networks with 3D U-Net architectures (model 1 and model 2) were trained on 310 CT scans for AR analysis.

Stroke volume index and transvalvular flow rate trajectories in severe aortic stenosis treated with TAVR.

Aims: The prognostic impact of flow trajectories according to stroke volume index (SVi) and transvalvular flow rate (FR) in patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR) remains poorly assessed. We evaluated and compared SVi and FR prior and after TAVR for severe AS.

Methods And Results: Patients were categorized according to SVi (<35 mL/m2) and FR (<200 mL/s).

Characteristics and immediate outcomes of patients who underwent percutaneous balloon mitral valvuloplasty at the Jakaya Kikwete Cardiac Institute, Tanzania.

Background: For rheumatic mitral stenosis (MS), a multidisciplinary evaluation is mandatory to determine the optimal treatment: medical, percutaneous balloon mitral valvuloplasty (PBMV) or valve surgery. Clinical and imaging evaluations are essential for procedural risk assessment and outcomes. PBMV interventions are increasingly available in Africa and are feasible options for selected candidates.

Methods: The NEOPRO-2 registry retrospectively included patients who underwent TAVR for severe aortic stenosis with either the NEO2 or PRO devices between August 2017 and December 2021 at 20 centres.

Myocardial infarction with non-obstructive disease and anomalous coronary origin: look for the common in the uncommon.

Management of congenital coronary artery anomalies (CAA) is not standardized due to the variety of conditions included and their rare prevalence. Detection of CAA during myocardial infarction with non-obstructive coronary arteries (MINOCA) may induce clinicians to address the patient for surgery as CAA is not included in any algorithm for the management of MINOCA and American Association for Thoracic Surgery evidence-based guidelines suggest surgical repair for patients with anomalous aortic origin of a coronary artery and symptoms compatible with myocardial ischaemia. We present the case of a 35-year-old man with an anomalous origin of left coronary artery from right Valsalva sinus with pre-pulmonic course detected during urgent coronary angiography for suspected myocardial infarction.

Patient selection, procedural planning and interventional guidance for non-valvular structural intervention.

Percutaneous non-valvular structural interventions, encompassing patent foramen ovale, atrial or ventricular septal defect closure and left atrial appendage closure, are usually performed in young and healthy patients and represent a valid alternative to pharmacological or surgical interventions. In order to minimize procedural and device related complications, a careful pre-procedural planning together with an accurate intra-procedural imaging are crucial to improve patient's outcome. In this article, we review currently available evidence on patient selection, procedural planning and interventional guidance helping physician to determine who will derive the most benefit from the procedure.

We report the challenging case of percutaneous treatment of early recurrent mitral regurgitation after Alfieri edge-to-edge surgical procedure.

Finite element analysis of transcatheter aortic valve implantation: Insights on the modelling of self-expandable devices.

Computational simulations of Transcatheter Aortic Valve Implantation (TAVI) have reached a high level of complexity and accuracy for the prediction of possible implantation scenarios during the decision-making process. However, when focusing on the prosthetic device, currently different devices are available on the market which not only have different geometries, but also different material properties. The present work focuses on the calibration of Nitinol constitutive parameters of four self-expandable devices starting from experimental radial force tests on the prosthetic samples.
