**Introduction/Hypothesis:**
Background: Right ventricular (RV) pseudoaneurysm is a rare, life-threatening complication associated with ischemia, infection, or trauma. With no unique clinical findings, identification relies on advanced imaging such as computed tomography angiography (CTA) and magnetic resonance imaging (MRI).

**Methods**
Case: We present a 75-year-old female with a medical history of pulmonary hypertension, bilateral orthotopic lung transplant, hypertension, and paroxysmal atrial fibrillation, who was transferred from an outside hospital for continued management of acute hypoxic respiratory failure. She arrived mechanically ventilated and hemodynamically stable. An initial CTA demonstrated an incidental RV apex pseudoaneurysm.

**Results**
Decision-making: Due to limited view with transthoracic echocardiogram (TTE), an electrocardiogram (ECG) gated CTA was performed, which confirmed the diagnosis. The etiology of the patient’s RV pseudoaneurysm remains unknown. Due to her critical respiratory condition, conservative management was recommended.

**Conclusion**
Conclusion: ECG-gated cardiac CT angiography, with its excellent spatial and temporal resolution should be considered as a form of diagnostic confirmation for suspected RV pseudoaneurysms, especially in cases where TTE is non-diagnostic.



Streamlining the Initial Diagnostic Pathway: Cardiac CT Angiogram in Right Ventricular Pseudoaneurysm

This course will explore basic and cutting-edge imaging techniques to improve patient care and hone individual skills in performance and interpretation of echocardiography, nuclear cardiology, cardiac computed tomography, and cardiovascular magnetic resonance imaging. Days will reinforce how cardiovascular imaging may improve comprehension in ischemic heart disease, structural heart disease, cardiomyopathies, and heart failure. Experts will utilize novel techniques to reinforce key topics including taped interventional cases and a strong emphasis on case presentations.
