Reversible Takotsubo cardiomyopathy with non-revascularized concomitant severe coronary artery disease

Area of Science:

• Cardiology
• Cardiac Imaging
• Internal Medicine

Background:

• Takotsubo cardiomyopathy (TTC) is a reversible heart condition often triggered by emotional or physical stress.
• TTC typically presents with symptoms similar to acute coronary syndromes, posing diagnostic challenges.
• Patients with pre-existing coronary artery disease (CAD) are not typically considered a primary demographic for TTC.

Observation:

• A male patient with severe three-vessel coronary artery disease (CAD) was scheduled for coronary artery bypass grafting (CABG).
• The patient experienced an episode consistent with Takotsubo cardiomyopathy prior to his scheduled surgery.
• Unusually, significant improvement in cardiac function was observed spontaneously before the planned revascularization procedure.

Findings:

• The case highlights a rare instance of Takotsubo cardiomyopathy in a patient with significant multi-vessel coronary artery disease.
• Rapid and complete spontaneous recovery of left ventricular function occurred before surgical intervention.
• This presentation challenges the typical understanding of TTC triggers and patient profiles.

Implications:

• The findings suggest that severe CAD may not preclude the development of TTC.
• Spontaneous recovery in TTC, even in complex cardiac patients, warrants further investigation.
• This case underscores the importance of considering TTC in the differential diagnosis of acute cardiac events, irrespective of underlying coronary anatomy.
