Title : Consideration of premature closure of atrial septal defect by thrombus in a patient with pulmonary Hypertension
Abstract: Pulmonary hypertension is defined as elevated mean pulmonary arterial pressure ≥25 mmHg at rest. It is subdivided into five different groups, one of which is group one pulmonary arterial hypertension (PAH), which is found to be associated with atrial septal defect (ASD). The presence of concomitant PAH and ASD is a significant consideration when deciding whether a patient’s ASD can be surgically repaired. It has been previously shown that surgical repair of an ASD in a patient with severe PAH may worsen right heart failure and cardiac output. We present a case of a patient with a concomitant PAH and ASD who presented with end-stage New York heart association (NYHA) class four pulmonary hypertension. The patient was known to have poor medical follow up and poor medical compliance contributing to a rapid decline in cardiac function. Upon evaluation with an echocardiogram, the patient was also found to have an atrial septal aneurysm and a thrombus in the right ventricle. Through this case, we explore the possibility of premature ASD closure and hemodynamic deterioration secondary to atrial thrombus formation in the setting of atrial septal aneurysm.
What will audience learn from your presentation?
(Try to list 3-5 specific items)
- They will learn medical knowledge regarding the topics of pulmonary arterial hypertension, atrial septal defects, atrial septal thrombi and atrial septal aneurysms
- A rare presentation of pulmonary hypertension will be presented and will create a discussion about how we we approach patients with atrial septal defects and pulmonary hypertension
- The audience will also learn about the previous research and novel cases of premature atrial septal closures
- This will inspire further research about the hemodynamic effects of premature closure of atrial septal defects
- This will improve the practice of clinicians and expand their knowledge base regarding pulmonary hypertension and atrial septal defects
