Are normal coronary arteries a typical feature of apical ballooning syndrome?

Area of Science:

• Cardiology
• Cardiovascular Diseases
• Clinical Case Reports

Background:

• Apical ballooning syndrome (ABS), also known as Takotsubo cardiomyopathy, is a transient left ventricular dysfunction.
• It is often triggered by emotional or physical stress and is a key differential diagnosis for acute myocardial infarction.
• A hallmark of ABS diagnosis is the absence of obstructive coronary artery disease.

Observation:

• This report details a unique case of a female patient presenting with symptoms consistent with ABS.
• However, diagnostic imaging revealed ultrasonographically confirmed tight stenosis in the right coronary artery.
• This finding contrasts with the typical absence of significant coronary artery disease in ABS.

Findings:

• The patient exhibited classic clinical and echocardiographic features of Apical ballooning syndrome.
• Despite the presence of significant coronary artery stenosis, other diagnostic criteria for ABS were met.
• This suggests a potential overlap or atypical presentation of ABS.

Implications:

• This case challenges the traditional diagnostic criteria for Apical ballooning syndrome.
• It underscores the importance of considering atypical presentations in the differential diagnosis of myocardial infarction.
• Further research is needed to understand the pathophysiology of ABS in the presence of coronary artery disease.
