Abrupt Closure

Pre-intervention

Shown below is a pre-intervention angiogram with narrowing of the lumen in the proximal part of obtuse marginal branch of left circumflex artery.

Normal speed

Slow motion

Intervention

Shown below is an angiogram with ongoing intervention on the narrowing described above.

Post-intervention

Shown below is a post-intervention angiogram with occlusion at the proximal part of obtuse marginal branch depicting abrupt closure.

Normal speed

Slow motion

Shown below is a post-intervention angiogram without any occlusion in the obtuse marginal branch of left circumflex artery after transient occlusion as seen above, which indicates transient abrupt closure.

Normal speed

Slow motion
