Advancements and applications of artificial intelligence in cardiovascular imaging: a comprehensive review.

Artificial intelligence (AI) is transforming cardiovascular imaging by offering advancements across multiple modalities, including echocardiography, cardiac computed tomography (CCT), cardiovascular magnetic resonance (CMR), interventional cardiology, nuclear medicine, and electrophysiology. This review explores the clinical applications of AI within each of these areas, highlighting its ability to improve patient selection, reduce image acquisition time, enhance image optimization, facilitate the integration of data from different imaging modality and clinical sources, improve diagnosis and risk stratification. Moreover, we illustrate both the advantages and the limitations of AI across these modalities, acknowledging that while AI can significantly aid in diagnosis, risk stratification, and workflow efficiency, it cannot replace the expertise of cardiologists.

Non-invasive physiological assessment of intermediate coronary stenoses from plain angiography through artificial intelligence: the STARFLOW system.

Background: Despite evidence supporting use of fractional flow reserve (FFR) and instantaneous waves-free ratio (iFR) to improve outcome of patients undergoing coronary angiography (CA) and percutaneous coronary intervention, such techniques are still underused in clinical practice due to economic and logistic issues.

Objectives: We aimed to develop an artificial intelligence (AI)-based application to compute FFR and iFR from plain CA.

Methods And Results: Consecutive patients performing FFR or iFR or both were enrolled.

[Ten questions about infective endocarditis].

Infective endocarditis (IE) is an infective process involving the endocardium and, more frequently, the native heart valves, valvular prostheses and cardiac implantable electronic devices. IE can manifest with various non-specific symptoms making the diagnosis challenging. This condition is associated with high in-hospital and long-term mortality.

Prevalence of left internal mammary artery disease in patients undergoing coronary angiography for suspected coronary artery disease: A meta-analysis and meta-regression study.

Left internal mammary artery (LIMA) to bypass left anterior descending artery has demonstrated to improve survival in multivessel coronary artery disease, but its routine angiography during index coronary angiography is seldom performed as LIMA is rarely diseased. A systematic literature review and meta-analysis was conducted using PubMed and Cochrane databases selecting the studies reporting prevalence of LIMA disease among patients undergoing coronary angiography and considered for CABG. Meta-regression analysis was performed to evaluate the prevalence of LIMA disease and the relative predictive value of canonical risk factors.

Efficacy and safety of left atrial appendage closure compared with oral anticoagulation in atrial fibrillation: a meta-analysis of randomized controlled trials and propensity-matched studies.

Backgrounds: Two recent randomized controlled trials (RCTs), the PROTECT-AF and the PREVAIL, showed that in atrial fibrillation (AF) patients, left atrial appendage closure (LAAC) is comparable to oral anticoagulants (OAC) in the prevention of stroke and could also possibly reduce mortality. Nevertheless, this net clinical benefit was not confirmed in the most recent RCT comparing LAAC vs. OAC, the PRAGUE-17 trial.

Comparison of mid-term mortality after surgical, supported or unsupported percutaneous revascularization in patients with severely reduced ejection fraction: A direct and network meta-analysis of adjusted observational studies and randomized-controlled.

Introduction: The optimal revascularization strategy in patients with heart failure with reduced ejection fraction (HFrEF) remains to be elucidated. The aim of this paper is to compare the mid-term mortality rate among patients with severely reduced ejection fraction (EF) and complex coronary artery disease who underwent coronary artery bypass grafting (CABG), percutaneous coronary intervention (PCI) with Impella support, or without.

Methods: Randomized control trials and propensity-adjusted observational studies including patients with ischemic cardiomyopathy (ICM) and severe EF reduction undergoing revascularization were selected.

Three-Dimensional Finger Test: A New Echocardiographic Method to Locate the Best Access Site During NeoChord Procedure.

Objective: Transventricular beating-heart mitral valve repair (TBMVR) with artificial chordae implantation is a technique to treat mitral valve prolapse. Two-dimensional (2D) echocardiography completed with simultaneous biplane view during surgeon finger pushing on the left ventricular (LV) wall (finger test [FT]) is currently used to localize the desired LV access, on the inferior-lateral wall, between the papillary muscles (PMs). We aimed to compare a new three-dimensional (3D) method with conventional FT in terms of safety and better localization of LV access.

Mortality across treatment strategies in intermediate-to-high risk pulmonary embolism in the modern era: A meta-analysis of observational studies and RCTs.

Introduction: Pulmonary embolism (PE) represents one of the leading causes of death worldwide and mainly treated with medical management, although the utility of more invasive approaches has emerged more recently. This meta-analysis aims to evaluate the 30-day mortality of intermediate-to-high risk PE across different treatment strategies.

Methods: A systematic literature review and meta-analysis was conducted using PubMed and Cochrane databases.

New Developments in the Management of Recurrent Pericarditis.

Recurrent pericarditis is a common and troublesome complication that affects 15%-30% of patients with a previous episode of pericarditis. However, the pathogenesis of these recurrences is not well understood, and most cases remain idiopathic. Recent advances in medical therapy, including the use of colchicine and anti-interleukin-1 agents like anakinra and rilonacept, have suggested an autoinflammatory rather than an autoimmune mechanism for recurrences with an inflammatory phenotype.

Two-Year clinical outcomes after coronary bifurcation stenting in older patients from Korea and Italy.

Background: Older patients who treated by percutaneous coronary intervention (PCI) are at a higher risk of adverse cardiac outcomes. We sought to investigate the clinical impact of bifurcation PCI in older patients from Korea and Italy.

Methods: We selected 5,537 patients who underwent bifurcation PCI from the BIFURCAT (comBined Insights from the Unified RAIN and COBIS bifurcAtion regisTries) database.

Management of Vascular Access in the Setting of Percutaneous Mechanical Circulatory Support (pMCS): Sheaths, Vascular Access and Closure Systems.

The use of percutaneous mechanical circulatory support (pMCS), such as intra-aortic balloon pump, Impella, TandemHeart and VA-ECMO, in the setting of cardiogenic shock or in protect percutaneous coronary intervention (protect-PCI) is rapidly increasing in clinical practice. The major problem related to the use of pMCS is the management of all the device-related complications and of any vascular injury. MCS often requires large-bore access, if compared with common PCI, and for this reason the correct management of vascular access is a crucial point.

Complex Coronary Interventions: Are We Reaching a Plateau?

[Percutaneous treatment of intermediate- and high-risk pulmonary embolism: two case reports].

Pulmonary embolism is the third most common cause of cardiovascular emergency. Risk stratification is crucial in the clinical and therapeutic management of these patients. The latest European guidelines introduced a new classification based on short-term mortality risk stratification, dividing patients into four categories (high, intermediate-high, intermediate-low and low risk).

Timing of impella placement in PCI for acute myocardial infarction complicated by cardiogenic shock: An updated meta-analysis.

Introduction: The timing of hemodynamic support in acute myocardial infarction complicated by cardiogenic shock (AMICS) has yet to be defined. The aim of this meta-analysis was to evaluate the impact of timing of Impella initiation on early and midterm mortality.

Methods: A systematic literature review and meta-analysis was conducted using PubMed and Cochrane databases.

Valve-in-Valve-in-Ring: A Bailout Strategy to Tackle Paravalvular Leaks due to Device Malapposition.

A 55-year-old male with a history of severe organic mitral regurgitation treated with surgical mitral valve (MV) repair was referred for a transcatheter MV replacement due to recurrent regurgitation. After the release of the first transcatheter MV, a severe paravalvular leak coming from the lateral side was observed. To promptly tackle this issue, a second valve with further postdilation was successfully implanted and the paravalvular leak disappeared.

Transcatheter Aortic Valve Implantation With or Without Predilation: A Meta-Analysis.

Aims: To evaluate the impact of systematic predilation with balloon aortic valvuloplasty (BAV) on transcatheter aortic valve implantation (TAVI).

Methods And Results: We performed a systematic meta-analysis investigating patients undergoing TAVI with systematic BAV vs no BAV in RCT or in adjusted studies. Device success was the primary endpoint, while all-cause mortality, 30-day moderate/severe aortic regurgitation (AR), stroke, permanent pacemaker implantation (PPI) and acute kidney injury (AKI) were the secondary endpoints.
