NSTEMI/SCAD vs. BRIDGE

Female 62y. old hospitalized in a regional hospital as NSTEMI.

Presented on September 23. with chest pain. ECG showed SVT with ST-segment depression. Baseline troponin level 1.8 (ref. value <0.04).

Risk factors for CVD: hypertension, obesity (BMI 36), positive family history of CVD

Referred for elective coronarography on December 1.

ECG:

Coronarography:

ECHO:

 

Coronarography was presented to 8 interventional cardiologists for interpretation.

Answers:

SCAD: 5

Bridge: 1

SCAD+Bridge: 2

 

Due to the lack of an OCT catheter the patient was referred to CTA.

 

CTA: calcified plaque in proximal LAD with 25% stenosis 20mm from ostium.  Medial LAD is very thin with loss of opacification at 50mm from ostium.

 

Control coronarography was done on December 23, with a plan to do OCT.

After NTG administration.

Initially planned OCT was not done.

Questions:

Do you agree with the myocardial bridge as a diagnosis?

Would you do an OCT after the administration of NTG?

What are possible adverse events in OCT imaging of the coronary artery with a myocardial bride?
