The Impact of Myocardial Bridging on Fractional Flow Reserve

open access: yes, 2022
Arterial stenosis is a problem of immediate significance, as cardiovascular disease is the number one leading cause of death worldwide. Fractional flow reserve (FFR) was proposed to evaluate the functional severity of coronary plaque-induced stenosis more accurately. FFR relies on invasive pressure measurements, while computational fluid dynamics (CFD)

Myocardial perfusion imaging by single-photon emission tomography (MPI SPECT) versus Instantaneous wave-free ratio (IFR) for assessment of functional significance of intermediate coronary artery lesions

open access: yesThe Egyptian Heart Journal, 2019
Background The aim of our work was to compare the myocardial perfusion imaging by single-photon emission tomography (MPI-SPECT) as a non-invasive, relatively non-expensive test versus the instantaneous wave-free ratio (IFR) for the evaluation of ...

Extensive unroofing of myocardial bridge: A case report and literature review

open access: yesSAGE Open Medical Case Reports, 2019
Background: Myocardial bridge is defined as a segment of a coronary artery that takes an intramyocardial course. The presence of myocardial bridge has been observed in as many as 40%–80% of cases on autopsy, angiographically from 0.5% to 16.0%, and often

A case of myocardial muscular bridging causing severe hypotension during exercise-electrocardiography test

open access: yesTürk Kardiyoloji Derneği Arşivi, 2016
Outlining the severity of the myocardial bridge (MB) is a critical step for selecting the appropriate option among medical, surgical, or angioplasty-based treatments.

Prognostic Value of Fractional Flow Reserve Measured Immediately After Drug-Eluting Stent Implantation [PDF]

open access: yes, 2017
The predictive value of fractional flow reserve (FFR) measured immediately after percutaneous coronary intervention (PCI) with drug-eluting stent placement has not been prospectively investigated.

Functional assessment in acute coronary syndrome: a systematic review of acute versus staged interventions

open access: yesREC: Interventional Cardiology (English Ed.)
Introduction and objectives: Several tools have been implemented to assess the functional significance of coronary lesions. Their reliability in the management of acute coronary syndrome (ACS) might be affected by alterations in the acute phase that go ...

Retracted: Microvascular resistance reserve in the presence of functionally significant epicardial stenosis and changes after revascularization

open access: yesPhysiological Reports, 2023
In the presence of functionally significant epicardial lesions, microvascular resistance reserve (MRR) calculation needs incorporation of collateral flow.

Personalised fractional flow reserve: a novel concept to optimise myocardial revascularisation

open access: yesEuroIntervention, 2019
Fractional flow reserve (FFR) represents the percentage reduction in coronary flow relative to a hypothetically normal artery; however, percutaneous coronary intervention (PCI) seldom achieves physiological normality (FFR 1.00), particularly in the context of diffuse disease.

Clinical and Vessel Characteristics Associated With Hard Outcomes After PCI and Their Combined Prognostic Implications

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background Cardiac death or myocardial infarction still occurs in patients undergoing contemporary percutaneous coronary intervention (PCI). We aimed to identify adverse clinical and vessel characteristics related to hard outcomes after PCI and to ...

Rheumatoid Arthritis and Coronary Artery Calcium Progression: A Case Cohort Analysis From ELSA‐Brasil

open access: yesArthritis Care &Research, EarlyView.
Objective To investigate the association between rheumatoid arthritis (RA) and coronary artery calcium (CAC) prevalence, incidence, and progression over four years in adults without prior cardiovascular disease. Methods A case‐cohort study within the Brazilian Longitudinal Study of Adult Health (ELSA‐Brasil) included 585 participants (86 patients with ...
