Abstract

RATIONALE:

Chronic total occlusion continues to be a challenging lesion subset for percutaneous coronary intervention.

PATIENT CONCERNS:

A 65-year-old male patient was admitted with symptoms of angina pectoris for 9 months.

DIAGNOSES:

Coronary angiography showed a severe stenosis in the proximal left anterior descending artery and a chronic total occlusion (CTO) in the proximal right coronary artery. The complexity of the CTO was stratified using the J-CTO score and the PROGRESS CTO score.

INTERVENTIONS:

Antegrade wire escalation for CTO of RCA failed. The septal collaterals to RCA were initially judged to be poor and not suitable for intervention.

OUTCOMES:

However, administration of sodium nitroprusside improved collateral flow and enabled the identification of retrograde channels suitable for wire crossing and successful retrograde PCI.

LESSIONS:

The study showed that faintly visible to even invisible septal collateral connections can be crossed with the septal "trial and error" surfing technique after the administration of sodium nitroprusside.
