Cardiac CT for the Assessment of Ischemic Cardiomyopathy

Journal of the Korean Society of Radiology
Ischemic cardiomyopathy is a major cause of heart failure, and the accurate assessment of myocardial ischemia, infarction, and tissue characteristics is essential for therapeutic decision- making.

Diagnostic Accuracy and Feasibility of Quantitative Flow Ratio at Low Frame Rate Angiography: The Prospective Multicentre Australian AVALON Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Quantitative Flow Ratio (QFR) is a well‐established, non‐hyperemic, angiographic, wire‐free predictor of ischemia when compared to Fractional Flow Reserve (FFR). However, its diagnostic accuracy at low frame rates (< 10 frames/second), commonly used in contemporary practice to minimize radiation exposure, has not been evaluated ...

Clinical Impact of Adherence to Fractional Flow Reserve Guidance in Acute Coronary Syndrome

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Fractional flow reserve (FFR) is established to guide revascularization in stable coronary disease and non‐culprit lesions in acute coronary syndromes (ACS). However, real‐world adherence to FFR guidance across the spectrum of ACS presentations, including ambiguous culprit scenarios, remains incompletely characterized.

Controversies in fractional flow reserve

, 2016
Fractional flow reserve (FFR) has been identified as the optimal diagnostic tool to identify significant coronary lesion. However, current evidence does not support this role.

Maximum Allowable Contrast Dose and Risk of Acute Kidney Injury After Coronary Procedures

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Recent studies have questioned whether iodinated contrast is causally related to acute kidney injury (AKI). AIM We pursed a contemporary analysis to determine the impact of contrast dose on AKI following coronary procedures in an era of lower contrast doses and less nephrotoxic agents.

Incidence of Periprocedural Myocardial Injury and Infarction After Intravascular Lithotripsy for Calcified Coronary Artery Stenosis

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Intravascular lithotripsy (IVL) has emerged as an effective technique for modifying heavily calcified coronary plaques, facilitating optimal stent expansion while minimizing procedural complications. However, data on periprocedural myocardial injury (PMI) and infarction (PPMI) following IVL remain scarce.

Five‐Year Clinical Outcomes of Biodegradable Versus Durable Polymer Drug‐Eluting Stents: A Propensity Score‐Matched Analysis of 4394 Patients

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Biodegradable‐polymer (BP) drug‐eluting stents (DES) were developed to mitigate potential late adverse events related to persistent durable polymers in durable‐polymer (DP) DES; however, contemporary long‐term real‐world comparative data remain limited. Aims We aimed to compare the 5‐year clinical outcomes of contemporary BP‐DES and

Impaired Flow and Physiology in Coronaries With Anomalous Origin From the Opposite Sinus of Valsalva

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Anomalous Aortic Origin of a Coronary Artery (AAOCA) high‐risk anatomical features (intramural segment, acute take‐off angle, slit‐like ostium) cause coronary stenosis leading to myocardial infarction. How these features alter coronary physiology remains unclear.

Biventricular Pressure‐Volume Loop Analysis in an LVAD Patient Optimized With Impella RP Flex

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Right ventricular (RV) failure after left ventricular assist device (LVAD) implantation is a serious complication which may necessitate temporary mechanical support in refractory cases. Here we describe a 63‐year‐old man with end‐stage ischemic cardiomyopathy and severe combined pre‐ and post‐capillary pulmonary hypertension who developed ...
