Spontaneous Coronary Artery Dissection with Cardiac Tamponade

Area of Science:

• Cardiology
• Vascular Medicine

Background:

• Spontaneous coronary artery dissection (SCAD) is an uncommon cause of acute coronary syndrome (ACS).
• Optimal treatment strategies and long-term prognosis for SCAD remain poorly understood due to its rarity and unclear pathophysiology.
• SCAD can present with a spectrum of symptoms, from mild chest pain to life-threatening conditions like ST-segment-elevation myocardial infarction (STEMI) and sudden cardiac death.

Observation:

• A 70-year-old woman presented with an acute STEMI attributed to spontaneous dissection of the left anterior descending coronary artery.
• Initial conservative management was initiated.
• Cardiac tamponade developed 16 hours post-presentation, with repeat angiography showing dissection extension.

Findings:

• The patient's cardiac tamponade was managed with pericardiocentesis, and medical therapy was continued.
• Despite the dissection extension and tamponade, the patient experienced a successful outcome.
• She remained asymptomatic at a 3-year follow-up, marking the first reported conservative treatment success for SCAD with cardiac tamponade.

Implications:

• This case suggests that conservative management, including pericardiocentesis, may be a viable option for select SCAD patients presenting with cardiac tamponade.
• Further research into SCAD pathophysiology and treatment outcomes is crucial for optimizing patient care.
• Successful conservative management in this rare SCAD complication provides valuable insights into potential therapeutic approaches and long-term recovery possibilities.
