From right to left heart failure: an unexpected transition.

Area of Science:

• Cardiology
• Internal Medicine
• Pulmonology

Background:

• Right-sided heart failure commonly results from left-sided failure.
• Pulmonary embolism is a known cause of acute right ventricular strain.

Observation:

• A rare clinical scenario involving a transition between two distinct heart failure etiologies was observed.
• The patient initially presented with right heart failure secondary to pulmonary embolism.

Findings:

• Resolution of pulmonary embolism was followed by the rapid onset of left heart failure.
• The subsequent left heart failure was attributed to Tako-tsubo (stress) cardiomyopathy.

Implications:

• This case underscores the dynamic nature of heart failure and the potential for rapid shifts in cardiac dysfunction.
• Clinicians should consider diverse and evolving etiologies in patients with heart failure, even after initial diagnosis and treatment.
• The transition highlights the importance of continuous monitoring and reassessment in managing complex cardiac conditions.
