Reconstruction of coronary arteries from X-ray angiography: A review. [PDF]

, 2016
Despite continuous progress in X-ray angiography systems, X-ray coronary angiography is fundamentally limited by its 2D representation of moving coronary arterial trees, which can negatively impact assessment of coronary artery disease and guidance of ...

Impact of Coronary Calcification on Complete Revascularization in Patients With Acute Coronary Syndrome and Multivessel Disease

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Coronary calcification is a well‐known marker of atherosclerotic plaque burden and a determinant of stent under expansion with unfavorable long‐term outcomes. Aims This sub study of the randomized BIOVASC trial aimed to compare immediate complete revascularization (ICR) and staged complete revascularization (SCR) in patients with ...

Cardiac Magnetic Resonance Imaging in Patients with Acute Ischemic Stroke and Elevated Troponin: A TRoponin ELevation in Acute Ischemic Stroke (TRELAS) Sub-Study

Cerebrovascular Diseases Extra, 2019
Background: Elevated high-sensitive cardiac troponin (hs-cTn) can be found in more than 50% of the patients with acute ischemic stroke. The observational TRoponin ELevation in Acute ischemic Stroke (TRELAS) study revealed that about 25% of all stroke ...

Complementary CT Coronary Angiography after Negative Selective Coronary Angiography

Journal 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.

Enhanced Drug Effect With Cutting Balloon Followed by Drug Coated Balloon in a Rabbit Model

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Drug‐coated balloon (DCB) are effective treatment options for patients with coronary artery disease and using of scoring or cutting balloon before the DCB usage were recommended. However, the effectiveness of lesion preparation with cutting balloons (CB) followed by DCB (CB + DCB) has not been evaluated before.

Combined analysis of coronary arteries and the left ventricular myocardium in cardiac CT angiography for detection of patients with functionally significant stenosis [PDF]

arXiv, 2019
Treatment of patients with obstructive coronary artery disease is guided by the functional significance of a coronary artery stenosis. Fractional flow reserve (FFR), measured during invasive coronary angiography (ICA), is considered the gold standard to define the functional significance of a coronary stenosis.
