Abstract:
Postoperative left ventricular pseudoaneurysm is a rare, but potentially lethal, complication because of the high risk of rupture and high mortality of repair. We report a 64-year-old man with Marfan syndrome who underwent the reimplantation valve-sparing aortic root replacement complicated by a postoperative left ventricular pseudoaneurysm that required urgent repair. Careful handling of the aortic root is required to avoid a left ventricular pseudoaneurysm, particularly in patients with connective tissue disorder.
Insights
Postoperative left ventricular pseudoaneurysm is a rare but lethal complication. Careful aortic root handling is crucial to prevent this, especially in Marfan syndrome patients.
Area of Science:
- Cardiovascular Surgery
- Cardiac Surgery Complications
- Connective Tissue Disorders
Background:
- Left ventricular pseudoaneurysm (LVPA) is a rare, life-threatening complication following cardiac surgery.
- High rupture risk and mortality associated with LVPA repair necessitate preventative strategies.
Observation:
- A 64-year-old male with Marfan syndrome developed a postoperative left ventricular pseudoaneurysm after valve-sparing aortic root replacement.
- The pseudoaneurysm necessitated urgent surgical repair.
Findings:
- Meticulous surgical technique during aortic root procedures is essential for preventing LVPA.
- Patients with connective tissue disorders, such as Marfan syndrome, may be at increased risk.
Implications:
- Highlights the critical importance of careful aortic root management in preventing LVPA.
- Emphasizes heightened vigilance for this complication in patients with underlying connective tissue abnormalities.
