Summary
A novel metal-free biovascular scaffold (BVS) can distort in the left main artery during stenting. This distortion is undetectable by angiography but visible with optical coherence tomography (OCT).
Area of Science:
- Cardiovascular Interventions
- Medical Device Technology
Background:
- The everolimus-eluting biovascular scaffold (BVS) is a metal-free alternative for coronary stenting.
- Its non-metallic nature makes struts invisible on standard angiography.
- Radiopaque markers aid in visualizing stent ends.
Observation:
- A case of anomalous stenting in the left main artery using BVS is presented.
- The BVS experienced accidental distortion within the left main during the procedure.
- This distortion was not apparent on conventional angiography.
Findings:
- Optical coherence tomography (OCT) is crucial for detecting BVS distortions.
- Angiography alone may fail to reveal structural abnormalities of the BVS in complex anatomies.
Implications:
- OCT imaging is recommended for BVS placement, especially in challenging locations like the left main.
- This highlights the importance of advanced imaging modalities for interventional cardiology.
- Ensures accurate assessment of scaffold deployment and integrity.

Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage.

Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...
