Intracoronary stent visualized on transesophageal echocardiogram in a case of coronary dissection complicated by...

Area of Science:

• Cardiology
• Vascular Surgery
• Medical Imaging

Background:

• Myocardial infarction necessitates timely intervention, often involving percutaneous coronary intervention.
• Coronary interventions carry risks, including iatrogenic vascular injury such as dissection.
• Aortic dissection is a life-threatening condition involving a tear in the aorta's inner layer.

Observation:

• A patient experienced a myocardial infarction and underwent coronary intervention.
• The intervention resulted in a coronary artery dissection that extended to involve the aorta, causing an aortic dissection.
• Transesophageal echocardiography was utilized for diagnostic imaging.

Findings:

• The coronary dissection was successfully treated with the placement of coronary stents.
• Intracoronary stent material was visualized within the intimal flap of the aortic dissection via transesophageal echocardiogram.
• The complex aortic dissection, complicated by the coronary intervention, was managed conservatively with favorable outcomes.

Implications:

• This case highlights a rare but serious complication of coronary intervention, emphasizing the importance of meticulous technique.
• Transesophageal echocardiography is crucial for diagnosing and characterizing complex aortic dissections, especially when related to interventions.
• Conservative management can be a viable option for certain types of aortic dissections, even in the presence of intracoronary devices.
