Rotational Atherectomy-Assisted Crossing of a Complex Right Coronary Artery Lesion Using the Retrograde Approach

Area of Science:

• Cardiovascular Medicine
• Interventional Cardiology
• Vascular Biology

Background:

• Chronic total occlusions (CTO) pose significant challenges in percutaneous coronary intervention (PCI).
• Developing effective strategies for CTO recanalization is crucial for improving patient outcomes.
• Retrograde approaches are often necessary for complex CTO cases.

Observation:

• A case involving a complex totally occluded right coronary artery is presented.
• The proximal cap of the lesion required modification to facilitate guidewire access.
• Successful guidewire manipulation into the vessel architecture was achieved.

Findings:

• Rotational atherectomy was successfully employed to modify the proximal cap of the CTO lesion.
• This modification enabled the subsequent placement of a guidewire for retrograde PCI.
• The combined approach led to the successful recanalization of the occluded artery.

Implications:

• Rotational atherectomy can be a valuable tool for preparing complex CTO lesions for retrograde PCI.
• This technique may expand treatment options for challenging coronary artery occlusions.
• Successful CTO intervention can restore myocardial perfusion and improve cardiac function.
