Clinical Information

Patient initials or Identifier Number

A.I.

Relevant Clinical History and Physical Exam

Stable angina. EF - 55%. Hypokinesis of the anterior wall of the left ventricular myocardium. Anterior myocardial infarction 6 years ago. The previous two months is a decrease in exercise tolerance. Exercise test positive. Poor quality of life.

Relevant Test Results Prior to Catheterization

Hematology:RBC - 4,600 10x12 cell/l;HGB - 131,000 g/l; PLT - 220,000 10 in 9 cell/l; MPV - 8,500 cube micron; PCT - 0,190%; PDW - 16,500 %; Lei - 5,300 10x9 cell/l;


Relevant Catheterization Findings

RCA dominant. LAD occlusal, distal part of artery is supplied by collaterals.

Interventional Management

Procedural Step

The Place of occlusion of the LAD isn’t visualized in angio. We performed OCT pullback from CX to Left Main. Two millimeters (2mm) early of ostium of first marginal branch was detection occlusal ostium of LAD with significance of endothelisation of ostium. The distal tip of the guidewire was formed using the "double wire bend" technique. LAD recanalization has been successfully completed. PCI DES from Left Main to LAD; final kissing-ballons (3.0x15mm in LAD) and  (3.0x15mm in CX); final POT 5.0x10mm ballon.

Case Summary

Intravascular imaging (OCT) makes to perform recanalization of CTO more safely and more efficiently. The quality of picture by OCT depends on the length of the occluded area and the presence of good collaterals.
