Calcified Plaque Detachment: Alternative Calcified Plaque Modification After Coronary Intravascular Lithotripsy

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Calcified plaque (CP) detachment (CD) and calcium fracture (CF) can occur following coronary intravascular lithotripsy (IVL). The extent to which CF alone facilitates stent expansion during CP modification with IVL remains unclear. Aims This study aimed to investigate the clinical implications of IVL‐induced CD.

Complementary CT Coronary Angiography after Negative Selective Coronary Angiography

open access: yesJournal of the Belgian Society of Radiology, 2015
A 53-year-old male was admitted for typical acute chest pain. The ECG showed a mirror image of posterior myocardial ischemia. Initial biology was normal but cardiac markers (creatine kinase and troponin) rose later. Echocardiography did not reveal any hypokinetic myocardial segment. There was no left ventricular dysfunction or valvular disease.

Comparison of Immediate Versus Staged Complete Revascularization in Patients With Index PCI Coronary Complications: A Study on Clinical Outcomes and Predictors of Complications

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background In patients with acute coronary syndrome (ACS) and multivessel disease (MVD), complete revascularization (CR) improves clinical outcomes compared with culprit‐only percutaneous coronary intervention (PCI). However, the optimal timing of CR, immediate (ICR) versus staged (SCR), remains debated.

Intraoperative direct coronary angiography clarifying a misleading coronary stenosis caused by an ascending aortic floating thrombus: a case report

open access: yesJournal of Cardiothoracic Surgery
Background Ascending aortic thrombus is an uncommon entity that may mimic primary aortic tumors. When aortic masses coexist with suspected coronary stenosis, conventional coronary angiography may increase the risk of thrombus embolization.

VERMONT μQFR: Diagnostic Accuracy of Murray Law‐Based 2D‐μQFR Compared to 3D‐μQFR and vFFR

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Murray law‐based quantitative flow ratio (μQFR) is an angiography‐derived physiological index that utilizes a single angiographic projection with artificial intelligence‐guided vessel segmentation. Aims To evaluate the diagnostic accuracy and time efficacy of 2D‐μQFR against wire‐based fractional flow reserve (FFR ≤ 0.80), compare ...

Three dimensional rotational angiography imaging of double aortic arch vascular ring [PDF]

open access: yes, 2013
Three dimensional (3D) rotational angiography is a technique used increasingly for imaging in congenital heart disease. Here the use of this technique for imaging of double aortic arch vascular ring is described and the advantages of this modality. are

New Techniques of Recording and Interpretation of Dynamic Coronary Angiography

open access: yes, 2023
In the study of coronary artery disease (CAD), the mechanism of plaque formation and development was still the subject of continuing debate. The limitation of the current coronary angiogram (CAG) is that it can only show the static image of a narrowing ...

Evaluation of Treatment Response of Calcified Nodules and Nodular Calcified Lesions Using Mean Density on Coronary Computed Tomography Angiography

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Calcified nodules (CN) and nodular calcifications (NC) present significant challenges during percutaneous coronary intervention (PCI) because of their protruding morphology and high rigidity, which often result in inadequate stent expansion and suboptimal procedural outcomes.

Coronary Angiography with Multidetector Row Computed Tomography: Comparison With Catheter Coronary Angiography

open access: yes, 2015
Purpose: We aimed to determine the potential and accuracy of multidetector computed tomography (MDCT) coronary angiography with an eight-row scanner in the evaluation of coronary artery disease, and find the best reconstruction percen-tiles for motion ...
