Article Synopsis
- A study evaluated the effectiveness of closing a patent foramen ovale (PFO) after a cryptogenic stroke, comparing those who had it done within 9 months (early closure) to those who had it done after 9 months (delayed closure).
- The research found no significant differences in recurrence rates of cerebrovascular events or systemic embolisms between the early and delayed closure groups, indicating similar outcomes regardless of when the procedure was performed.
- The results suggest that PFO closure might be beneficial even in patients with a cryptogenic event that occurred more than 9 months ago, challenging the notion that the timing of the closure is critical.
Objectives: Confirming the prognostic value of global QFR and evaluating the long-term prognosis of QFR-concordant therapy in stable coronary artery disease.
Background: Wire-based functional evaluation of coronary disease is linked to patient's prognosis. Quantitative Flow Ratio (QFR) is a newer index of computational physiology, linked to clinical outcomes and prognosis at 1 year follow-up.
Article Synopsis
- A study evaluated the long-term effects (5 years) of complete bioresorbable vascular scaffold (BVS) resorption on both structural healing and blood vessel function in patients who received the ABSORB-BVS treatment.* -
- The research included 31 patients, showing that while the scaffolds completely dissolved, there were concerning vasomotor responses, such as vasoconstriction after acetylcholine and lack of response to nitroglycerine in the treated blood vessels.* -
- New coronary lesions developed in some patients, indicating potential complications, and while the scaffolds were gone, the expected restoration of healthy blood vessel function was not fully achieved.*
We systematically categorized the longer-term (≥3 years) structural and functional characteristics of the ABSORB bioresorbable vascular scaffold (BVS) using optical coherence tomography imaging and coronary vasomotor reactivity testing and further compared the functional characteristics of BVS stented versus remote coronary segments. A total of 92 patients (mean age 56.4 ± 9.
