Summary
Transcatheter interventions effectively repaired complex ascending aortic pseudoaneurysms (PsA) in high-risk patients. Real-time 3D TEE guided device selection and procedural success for these challenging aortic conditions.
Area of Science:
- Cardiovascular Surgery
- Interventional Cardiology
- Medical Imaging
Background:
- Ascending aortic pseudoaneurysm (PsA) presents significant surgical challenges with high morbidity and mortality.
- Transcatheter intervention offers a less invasive alternative for patients unsuitable for repeat open surgery.
Observation:
- Three patients with complex ascending PsA post-cardiac or aortic root surgery underwent transcatheter repair.
- Real-time 3D transesophageal echocardiography (RT 3D TEE) combined with fluoroscopy was utilized for perioperative monitoring.
Findings:
- Successful occlusion of all ascending PsA was achieved using various transcatheter techniques (transapical, transarterial, transvenous/hybrid).
- RT 3D color Doppler TEE proved crucial for selecting appropriate occluder devices and guiding catheter navigation through complex anatomies.
Implications:
- Transcatheter and hybrid interventions are effective for complex ascending PsA when carefully planned with strong teamwork.
- RT 3D TEE is invaluable for precise device selection and procedural guidance in challenging aortic interventions.

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...

583
Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...
