Coronary Flow and Myocardial Viability: the FloVITA Study
An observational study of Myocardial Infarction and Myocardial Ischemia, run by Centre Hospitalier Universitaire de Besancon at 1 site in France.
Trial summary
Evaluation of fractional flow reserve (FFR) is a key method for assessing ischemia with a view to guiding revascularization strategy following acute coronary syndrome. A stenosis that appears to be severe by angiography may cause limited ischemia (with an FFR value >0.80) due to the incapacity of the necrotic zone to… Read more about this study

About this study
Official title: Study of the Relationship Between Coronary Flow and Myocardial Viability: the Single-centre, Observational, Prospective FloVITA Study
Evaluation of fractional flow reserve (FFR) is a key method for assessing ischemia with a view to guiding revascularization strategy following acute coronary syndrome. A stenosis that appears to be severe by angiography may cause limited ischemia (with an FFR value >0.80) due to the incapacity of the necrotic zone to achieve physiological hyperemia, i.e. maximal coronary flow. Recently, it has been demonstrated that absolute coronary flow, and micro- and macrovascular resistance, as measured by a thermodilution technique, using the Rayflow microcatheter (Hexacath) are strongly associated with myocardial mass. In extensive necrosis, there is a loss of myocardial mass, and these tools could be of potential interest in measuring myocardial viability, which reflects the extent of remaining viable myocardial mass.
Therefore, this study aims to investigate the relationship between both absolute coronary flow and microvascular resistance, and myocardial viability assessed by MRI.
In a prospective, single-centre, interventional study, we will compare absolute coronary flow and microvascular resistance in the left anterior descending artery, in patients with and without a history of ST segment elevation MI.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Evaluation of fractional flow reserve (FFR) is a key method for assessing ischemia with a view to guiding revascularization strategy following acute coronary syndrome. A stenosis that appears to be severe by angiography may cause limited ischemia (with an FFR value >0.80) due to the incapacity of the necrotic zone to achieve physiological hyperemia, i.e. maximal coronary flow. Recently, it has been demonstrated that absolute coronary flow, and micro- and macrovascular resistance, as measured by a thermodilution technique, using the Rayflow microcatheter (Hexacath) are strongly associated with myocardial mass. In extensive necrosis, there is a loss of myocardial mass, and these tools could be of potential interest in measuring myocardial viability, which reflects the extent of remaining viable myocardial mass.
Therefore, this study aims to investigate the relationship between both absolute coronary flow and microvascular resistance, and myocardial viability assessed by MRI.
In a prospective, single-centre, interventional study, we will compare absolute coronary flow and microvascular resistance in the left anterior descending artery, in patients with and without a history of ST segment elevation MI.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Coronary flow (mL/min) in the LAD (time frame: At the end of the angiography procedure). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04818918, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Oct 2026.
