Percutaneous Coronary Intervention in Spontaneous Coronary Artery Dissection: Role of Intravascular Ultrasound

Area of Science:

• Cardiology
• Interventional Cardiology
• Vascular Medicine

Background:

• Spontaneous coronary artery dissection (SCAD) is a rare but serious cause of acute myocardial infarction.
• Diagnosis can be difficult due to severe narrowing of the true lumen on conventional coronary angiography.
• Percutaneous coronary intervention (PCI) in SCAD patients presents unique management challenges.

Purpose of the Study:

• To highlight the diagnostic and management challenges of SCAD.
• To illustrate the utility of intravascular ultrasound (IVUS) in SCAD cases.
• To demonstrate successful PCI guided by IVUS in a SCAD patient.

Main Methods:

• Case report detailing a patient with SCAD.
• Coronary angiography for initial diagnosis.
• Intravascular ultrasound (IVUS) for detailed anatomic assessment and procedural guidance.
• Percutaneous coronary intervention (PCI) with stent placement.

Main Results:

• Conventional angiography posed diagnostic challenges due to true lumen compromise.
• IVUS successfully identified the dissection site and guided accurate stent deployment.
• Successful PCI was achieved, confirming stent placement within the true lumen.

Conclusions:

• SCAD diagnosis and PCI require careful consideration.
• Intravascular ultrasound is a valuable tool for SCAD diagnosis and optimizing PCI outcomes.
• IVUS facilitates accurate stent placement in the true lumen, crucial for successful SCAD management.
