Coronary Flow Reserve Measured by Myocardial Perfusion Imaging in Patients Following Percutaneous Coronary Intervention

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Despite achieving complete revascularization, patients with coronary artery disease (CAD) may experience adverse outcomes, potentially attributable to coronary microvascular dysfunction (CMD). Coronary flow reserve (CFR), which integrates both epicardial and microvascular coronary function, and a reduced CFR following complete ...

Prevalence and Prognostic Impact of Coronary Chronic Total Occlusions in Patients With Cardiogenic Shock

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Mortality in patients with cardiogenic shock (CS) remains high despite advanced treatment strategies in CS patients, underlining the need for the identification of predictors of prognosis in CS patients. Therefore, the present study investigates the prognostic impact of coronary chronic total occlusions (CTO) in patients with CS ...

Validation of Coronary Wire for the Acquisition of Intracoronary Electrocardiogram in Swine

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background We report the first in‐literature animal experiment to validate the intracoronary ECG signal acquired from a coronary wire compared with the direct signal from an epicardial electrode. Methods An animal model study was performed in a 40 kg pig.
