Fractional flow reserve is a useful reference standard for myocardial perfusion studies with limitations [PDF]

European Heart Journal - Cardiovascular Imaging, 2014
Plein and Motwani1, in their editorial comment on a study by Ebersberger et al. 2 in the journal, state that because the ischaemia threshold of fractional flow reserve (FFR) was initially ‘validated’ in patients with unequivocal stress-induced ischaemia by stress SPECT/echocardiogram (ECHO),3 subsequent studies using FFR as a reference standard to ...

Clinical and Technical Predictors of Treatment Success After Coronary Intravascular Lithotripsy in Calcific Coronary Lesions

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Intravascular lithotripsy (IVL) is increasingly used to treat coronary artery calcification (CAC). This study aimed to identify clinical and procedural factors associated with IVL treatment success. Methods This retrospective analysis included 454 patients (73 ± 9 years, 75% male) treated with IVL from the multicenter BENELUX‐IVL ...

Correlation between catecholamines and echocardiographic parameters in patients with pheochromocytoma and paraganglioma

Journal of Clinical Ultrasound, Volume 51, Issue 1, Page 31-35, January 2023., 2023
This study aimed to examine the association between catecholamines and echocardiographic parameters indicative of cardiac damage in patients with PPGL. The conclusion is that catecholamine effects on the myocardium are reflected in echocardiographic diastolic function parameters.

Trends and Outcomes Following Percutaneous Coronary Intervention in Patients With Myeloproliferative Neoplasms: Insights From National Database

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Myeloproliferative neoplasms (MPN) are associated with an increased cardiovascular risk including acute coronary syndrome. However, there is a lack of comprehensive data regarding the rate of percutaneous coronary intervention (PCI), as well as the in‐hospital characteristics and outcomes for MPN patients.

The Relationship between Thrombolysis in Myocardial Infarction Frame Count and Fractional Flow Reserve in Patients with Moderate Coronary Stenosis Undergoing Coronary Angiography

پزشکی بالینی ابن سینا, 2017
Background and Objective: Thrombolysis in myocardial infarction (TIMI) frame count (TFC) is an objective and quantitative index of coronary flow, and myocardial fractional flow reserve (FFR) is a lesion-specific index for epicardial coronary stenosis ...

Impact of Post Percutaneous Coronary Intervention Fractional Flow Reserve on 5‐Year Clinical Outcomes (The FFR SEARCH Study)

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Fractional flow reserve (FFR) following percutaneous coronary intervention (PCI) can be used to evaluate procedural success and to guide stent optimization. Several studies have demonstrated that lower FFR after stent implantation is associated with increased adverse event rates up to 2 years.

The Impact of Hydrostatic Pressure on Fractional Flow Reserve in Saphenous Vein Grafts

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The relationship between height differences related to graft anatomy and physiological pressure indices in coronary bypass grafts has not been studied. We sought to study the impact of hydrostatic pressure on fractional flow reserve (FFR) in saphenous vein grafts (SVGs).
