Impact of incomplete ventricular coverage on diagnostic performance of myocardial perfusion imaging. [PDF]

, 2017
In the context of myocardial perfusion imaging (MPI) with cardiac magnetic resonance (CMR), there is ongoing debate on the merits of using technically complex acquisition methods to achieve whole-heart spatial coverage, rather than conventional 3-slice ...

Case report: Acute ST-elevation myocardial infarction and cardiogenic shock caused by a giant right sinus of Valsalva aneurysm and right coronary artery compression

Frontiers in Cardiovascular Medicine, 2022
A sinus of Valsalva aneurysm (SVA) is a rare aortic disease that may be congenital or acquired. Patients with an intact SVA are usually asymptomatic, whereas a ruptured SVA may cause acute chest pain and dyspnea.

Deep learning analysis of the myocardium in coronary CT angiography for identification of patients with functionally significant coronary artery stenosis

, 2017
In patients with coronary artery stenoses of intermediate severity, the functional significance needs to be determined. Fractional flow reserve (FFR) measurement, performed during invasive coronary angiography (ICA), is most often used in clinical ...

Left ventricular diastolic dysfunction worsens prognosis in patients with heart failure due to dilated cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1183-1193, April 2025.
Abstract Aims The prognostic significance of left ventricular (LV) diastolic dysfunction (LVDD) severity in patients with dilated cardiomyopathy (DCM) remains uncertain. This study aimed to evaluate the association of LVDD severity and elevated left atrial pressure (eLAP) with patient outcomes in stable, non‐acutely decompensated patients with DCM ...

Cardiogenic shock mortality according to Aetiology in a Mediterranean cohort: Results from the Shock‐CAT study

ESC Heart Failure, Volume 12, Issue 2, Page 1336-1345, April 2025.
Abstract Aims Mortality in cardiogenic shock (CS) remains elevated, with the potential for CS causes to impact prognosis and risk stratification. The aim was to investigate in‐hospital prognosis and mortality in CS patients according to aetiology. We also assessed the prognostic accuracy of CardShock and IABP‐SHOCK II scores.
