Differential Diagnosis for Mental Health Conditions in a Patient with Tricuspid Atresia Status Post Extracardiac Fontan Operation

• Single most likely diagnosis
  • Anxiety: This condition is commonly associated with patients who have undergone significant cardiac surgeries, such as the Fontan operation. The psychological impact of living with a chronic condition, coupled with the physical limitations and potential for complications, can contribute to anxiety.
• Other Likely diagnoses
  • Depression: Similar to anxiety, depression can be a consequence of dealing with the long-term effects of a serious cardiac condition and its treatment. The lifestyle adjustments and potential for future health issues can contribute to depressive symptoms.
• Do Not Miss
  • None specifically identified in the context of the question, but it's crucial to consider any condition that could significantly impact the patient's quality of life or pose a risk if not addressed. In the broader context of mental health, conditions like suicidal ideation or psychotic episodes (though less common) should be evaluated due to their potential severity.
• Rare diagnoses
  • Obsessive-compulsive disorder (OCD): While OCD can occur in anyone, there's no specific indication in the provided context that it would be more prevalent in patients with tricuspid atresia status post Fontan operation compared to the general population.
  • Schizophrenia: This is a chronic and severe mental disorder that affects how a person thinks, feels, and behaves. It is not specifically linked to cardiac conditions like tricuspid atresia or surgical interventions like the Fontan operation, making it a less likely diagnosis in this context.
