Clinical Information

Patient initials or Identifier Number

Patient M., 54 year old

Relevant Clinical History and Physical Exam

Patient M. 54 y.o., male, suffered within 5 years from Angina with mild exertion Class 3. Postinfarction Cardiosclerosis - Acute Miocardial Infarction 5 years agoArterial HypertensionDiabetes MellitusUnsuccessful attempts of Cx CTO recanalizations

Relevant Test Results Prior to Catheterization

Echocardioscopy: EF - 50%, Hypokinesia of apico-inferior, apico-lateral and apical segments

Relevant Catheterization Findings

Prolonged left type Cx in-stent occlusion from ostium to the distal bifurcation with ambiguous proximal cap at the left main trifurcation and epicardial and septal collateralsJ-CTO - 4ProgressCTO - 2

Interventional Management

Procedural Step

Patient had prolonged left type ostium Cx in-stent chronic total occlusion with ambiguous proximal cap and unclear distal cap. He had also well developed epicardial collateral from Intermediate to Cx and septal collaterals. Sion blue with Corsair successfully crossed septal loop and achieved the distal cap of occlusion near bifurcation. Tip injection was performed and shown false lumen position of distal occluded stent. Both antegrade and retrograde attempts were performed and channel dilatation allowed retrograde wire to place in guiding catheter. Trapping and externalization were performed. After predilatation 3 DES from Cx to LM were implanted. POT, TAP-stenting of IMA, trifurcation-kissing, post-POT consequently were performed.

Case Summary

CTOs are the most difficult and unpredictable procedures in coronary interventions and operator have to be ready to deal with all contemporary coronary techniques to achieve procedural success and to show reliable long-term result.
