Takotsubo Cardiomyopathy Coexisting with Acute Pericarditis and Myocardial Bridge

Area of Science:

• Cardiology
• Internal Medicine
• Pathophysiology

Background:

• Takotsubo cardiomyopathy (TCM) is a stress-induced cardiomyopathy predominantly affecting postmenopausal women.
• TCM clinically resembles acute coronary syndrome but features nonobstructive coronary arteries and transient left ventricular apical ballooning.
• The precise pathogenesis of TCM remains incompletely understood.

Purpose of the Study:

• To report an unusual case of Takotsubo cardiomyopathy presenting with symptoms of acute pericarditis.
• To investigate the potential impact of coexisting coronary artery anomalies, specifically a muscle bridge, on TCM pathogenesis.
• To enhance the understanding of TCM etiology through the analysis of this unique clinical presentation.

Main Methods:

• Case report detailing a patient with Takotsubo cardiomyopathy.
• Clinical presentation analysis including symptoms mimicking acute pericarditis.
• Coronary angiography to identify coronary anatomy and rule out obstructive coronary artery disease, revealing a coronary muscle bridge.

Main Results:

• The patient exhibited signs and symptoms consistent with acute pericarditis.
• Coronary angiography demonstrated a coexisting coronary muscle bridge.
• The case presents a unique combination of TCM, pericarditis symptoms, and a coronary muscle bridge.

Conclusions:

• This case underscores the diverse clinical presentations of Takotsubo cardiomyopathy.
• The association with acute pericarditis and a coronary muscle bridge may provide novel insights into the multifactorial pathogenesis of TCM.
• Further research is warranted to explore the interplay of these factors in TCM development.
