Background: Acquired von Willebrand factor (vWF) deficiency is a key contributor to bleeding after transcatheter aortic valve replacement (TAVR).
Objective: To evaluate whether assessing primary hemostatic disorder using closure time of adenosine diphosphate (CT-ADP), a marker of vWF dysfunction, enhances bleeding risk stratification in TAVR patients at high bleeding risk (HBR).
Methods: We analyzed 884 patients from a prospective TAVR registry.
Background: Elevated white blood cell (WBC) counts have been associated with major adverse cardiovascular events (MACE). However, their incremental prognostic values, especially considering factors such as race, sex difference, clinical characteristics, and statin dosage, are not well defined. This study aimed to explore the relationship between baseline WBC counts and subsequent MACE in Japanese patients with stable coronary artery disease (CAD) receiving high and low doses of pitavastatin, as a sub-analysis of the REAL-CAD study.

This study evaluates the impact of severe aortic atheroma on long-term outcomes following TAVR. We enrolled 977 patients who underwent TAVR between February 2010 and May 2019, with available contrast-enhanced computed tomography data.

Early detection of vascular aging is critical, as preclinical atherosclerosis often remains undiagnosed. AI-determined vascular age, originally developed using carotid-femoral pulse wave velocity (cf-PWV), may help to identify individuals at elevated risk.

Hypertension is a key modifiable risk factor contributing to elevated cardiovascular morbidity and mortality in this population. However, its prevalence and persistence remain underexplored.

We used MRI and advanced imaging modalities to assess a right-to-left shunt through an atrial septal defect without pulmonary hypertension (PH).
Case Summary: An 84-year-old woman with persistent hypoxemia was found to have a significant right-to-left shunt without PH.
Background: The effect of Intensified Multifactorial treatments on coronary atherosclerosis in PAtients with Coronary artery disease and Type 2 Diabetes Mellitus (IMPACT-DM) trial was designed to investigate the effects of intensified multifactorial treatments (IMT) on coronary plaque progression in patients with coronary artery disease (CAD) and diabetes.
Methods And Results: In this prospective, randomized, open-label, parallel assignment, multicenter study, eligible patients with diabetes who underwent successful percutaneous coronary intervention in culprit lesions are randomly assigned to receive either IMT or guideline-oriented standard treatments (Control) for 18 months. The IMT are managed according to strict target goals and step-by-step medical treatment protocols based on modern medical treatments.
We herein report a case of pacemaker lead-related tricuspid regurgitation in a repaired congenital heart disease patient, with a significant improvement in exercise tolerance and liver stiffness after surgery. Optimizing the timing of invasive procedures for tricuspid regurgitation is challenging because of an insufficient ability to predict the outcome, and percutaneous therapies have shown promising advancements in recent years. In this case, close monitoring with abdominal ultrasound and echocardiography facilitated our ability to select the optimal timing for surgical intervention.

However, reports of acute acalculous cholecystitis after pulmonary vein isolation are rare.
Case Summary: We report a case of a 64-year-old man diagnosed with paroxysmal atrial fibrillation.
Background: Data on clinical outcomes after intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) in patients with multivessel disease and left ventricular (LV) dysfunction are scarce.
Methods And Results: The OPTIVUS-Complex PCI study multivessel cohort was a prospective multicenter single-arm trial enrolling 1,010 patients undergoing multivessel IVUS-guided PCI including left anterior descending coronary artery target with an intention to meet the prespecified OPTIVUS criteria for optimal stent expansion. We compared clinical outcomes between patients with and without LV dysfunction.

It remains unknown whether intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) can improve the clinical outcomes of complex PCI to a level equivalent to that of non-complex PCI. In the OPTIVUS-Complex PCI (Optimal Intravascular Ultrasound-Guided Complex PCI) Study multivessel cohort, a total of 1011 patients who underwent multivessel PCI involving a target lesion in the left anterior descending coronary artery (LAD) were divided into 2 groups: complex PCI (N = 760) and non-complex PCI groups (N = 251). Complex PCI was defined as a procedure with the following characteristics: 3 vessels treated, 3 stents implanted, 3 lesions treated, bifurcation with 2 stents implanted, total stent length > 60 mm, or target of chronic total occlusion.

However, the optimal predilatation strategy prior to DCB dilatation has yet to be validated.
Methods/design: The NATURE (Non-stent PCI with an appropriate dilatation by means of cutting balloon and drug-coated balloon in de novo lesion) study is a prospective, multi-center, randomized controlled trial designed to evaluate the safety and efficacy of a cutting balloon compared to standard balloons (semi-compliant or non-compliant balloons) for lesion preparation prior to DCB treatment in normal-sized vessels.
Background: Aortic atherosclerosis can affect the strategy and outcomes of transcatheter aortic valve replacement (TAVR). Limited investigation exists into how aortic atheroma morphology influences outcomes post-TAVR.
Objectives: This study aimed to assess the influence of protruding and ulcerated aortic atheromas on periprocedural ischemic stroke post-TAVR.

Aims: Pre-existing myocardial fibrosis before aortic valve replacement (AVR) is a major cause of postoperative heart failure (HF). Evaluation of fibrosis by computed tomography extracellular volume (CT-ECV) may allow risk stratification for patients with severe aortic stenosis (AS) scheduled for transaortic AVR (TAVR) or surgical AVR (SAVR). We performed a meta-analysis to determine the prognostic value of CT-ECV for the prediction of adverse events in patients with severe AS scheduled for AVR.

However, the polymers, which have been the most common type of coatings used in drug-eluting stents, have some issues. The study aim was to evaluate the clinical outcomes of patients undergoing PCI with polymer-free sirolimus- and probucol-eluting stents (NP023).

Methods And Results: The REAL-CAD (Randomized Evaluation of Aggressive or Moderate Lipid Lowering Therapy With Pitavastatin in Coronary Artery Disease) study is a prospective, multicenter, randomized trial of high-dose (pitavastatin 4 mg/day) or low-dose (pitavastatin 1 mg/day) statin therapy in 12 118 patients with chronic coronary syndrome. The primary end point was a composite of cardiovascular death, nonfatal myocardial infarction, stroke, or unstable angina requiring hospitalization (major adverse cardiac and cerebral events [MACCE]).
