Insights
Acute aortic dissection can cause fatal coronary malperfusion. Prompt percutaneous coronary intervention to the left main trunk, before surgery, can stabilize patients with acute myocardial infarction and cardiogenic shock.
Area of Science:
- Cardiology
- Thoracic Surgery
- Vascular Medicine
Background:
- Acute aortic dissection (AAD) can lead to coronary malperfusion, a rare but life-threatening complication.
- Compression of the left main trunk (LMT) by a false lumen in AAD can cause acute myocardial infarction (AMI) and cardiogenic shock.
Observation:
- A case of AMI with cardiogenic shock was observed, resulting from LMT compression by a Stanford type A AAD.
- The patient underwent successful percutaneous coronary intervention (PCI) to the LMT, followed by definitive surgical repair under stable hemodynamic conditions.
Findings:
- Precedent PCI to the LMT effectively relieved global ischemia and achieved hemodynamic stability.
- This approach facilitated subsequent definitive surgery for Stanford type A AAD.
Implications:
- While LMT stenting in AAD is debated, precedent PCI may be a crucial strategy for managing AMI and cardiogenic shock.
- This case highlights the potential benefit of PCI as a bridge to surgery in complex AAD cases.
Abstract:
Coronary malperfusion due to acute aortic dissection (AAD) is a relatively rare, but fatal condition. We experienced a case of acute myocardial infarction (AMI) with cardiogenic shock due to compression of the left main trunk (LMT) by a false lumen of an AAD. Percutaneous coronary intervention (PCI) to the LMT was firstly performed, followed by a definitive surgery under a stable hemodynamic condition. Stanford type A AAD is an indication for emergency operation and stenting to the LMT is controversial. However, it might be an essential strategy to perform precedent PCI to the LMT which quickly relieves global ischemia, and achieves hemodynamic stability for the following definitive surgery.
