Interpretable Multimodal Learning for Cardiovascular Hemodynamics Assessment [PDF]

open access: yesarXiv
Pulmonary Arterial Wedge Pressure (PAWP) is an essential cardiovascular hemodynamics marker to detect heart failure. In clinical practice, Right Heart Catheterization is considered a gold standard for assessing cardiac hemodynamics while non-invasive methods are often needed to screen high-risk patients from a large population.

A Generalizable 3D Diffusion Framework for Low-Dose and Few-View Cardiac SPECT [PDF]

open access: yesarXiv
Myocardial perfusion imaging using SPECT is widely utilized to diagnose coronary artery diseases, but image quality can be negatively affected in low-dose and few-view acquisition settings. Although various deep learning methods have been introduced to improve image quality from low-dose or few-view SPECT data, previous approaches often fail to ...

Fractional Flow Reserve Directed Percutaneous Coronary Intervention Optimization Using High‐Definition Intravascular Ultrasound in Non‐ST‐Segment Elevation Acute Coronary Syndrome Versus Chronic Coronary Syndrome

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Intravascular ultrasound (IVUS)‐guided optimization of suboptimal fractional flow reserve (FFR) following percutaneous coronary intervention (PCI) results in a significant increase in both post‐PCI FFR and minimal lumen and stent areas (MLA and MSA, respectively).

Coronary Plaque Characteristics Assessed by Optical Coherence Tomography and Plasma Lipoprotein(a) Levels in Patients With Acute Coronary Syndrome

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Lipoprotein(a) [Lp(a)] is associated with increased cardiovascular risk, but its influence on plaque characteristics at optical coherence tomography (OCT) evaluation is not fully understood. Aims This study seeks to explore the impact of Lp(a) levels on plaque morphology as assessed by OCT in a very high‐risk subset of patients ...

Closure of a Late‐Onset Iatrogenic Left Ventricular Pseudoaneurysm Caused by Erosion of an Apical Muscular VSD Device

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT We report the case of a 3‐year‐old asymptomatic girl (12 kg, 96 cm) who was diagnosed with a large iatrogenic left ventricular pseudoaneurysm (LVP) on follow‐up ultrasound, 14 months after apical muscular ventricular septal defect (VSD) closure with a 10 mm Amplatzer Muscular VSD occluder (Abbott, USA) due to device erosion.

Steerable Delivery Sheath for Optimized LAA Closure: First Experience and Procedural Outcomes

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The new Amplatzer Steerable Delivery Sheath is a delivery system designed to improve ease‐of‐use and procedural results of left atrial appendage closure (LAAC). We aimed to compare procedural results after switching our LAAC program at a tertiary care center with the Amulet device to the Steerable Delivery Sheath, with a control ...
