Insights
Transapical aortic cannulation is a secure and effective method for repairing acute type A aortic dissections. This technique ensured sufficient cardiopulmonary bypass flow without malperfusion events in a study of 73 patients.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Aortic Surgery
Background:
- Acute type A aortic dissection is a life-threatening condition requiring prompt surgical intervention.
- Traditional cannulation methods can pose risks during aortic dissection repair.
- Transapical aortic cannulation offers an alternative approach for establishing cardiopulmonary bypass.
Purpose of the Study:
- To evaluate the safety and efficacy of transapical aortic cannulation in patients undergoing surgical repair for acute type A aortic dissection.
Main Methods:
- Transapical aortic cannulation was performed in 73 patients with acute type A aortic dissection between June 2003 and November 2006.
- A 7-mm flexible cannula was inserted via a left ventricular apical incision under transesophageal echocardiography guidance.
- Procedures included 64 hemiarch repairs and 9 total arch replacements.
Main Results:
- Sufficient cardiopulmonary bypass flow was achieved in all cases.
- No instances of malperfusion were reported.
- The procedure was found to be secure and effective.
Conclusions:
- Transapical aortic cannulation is a safe and useful technique for the surgical management of acute type A aortic dissection.
- This method facilitates adequate cardiopulmonary bypass and avoids malperfusion complications.
- It represents a viable option for aortic dissection repair.
Abstract:
From June 2003 to November 2006, transapical aortic cannulation was performed in 73 patients (41 men and 32 women, mean age 63 years, 64 hemiarch repair and 9 total arch replacement) with acute type A aortic dissection. A 1-cm incision was made in the apex of the left ventricle, and a 7-mm soft and flexible cannula was passed through the apex and across the aortic valve until positioned in the ascending aorta under guidance by transesophageal echocardiography. In all cases, cardiopulmonary bypass flow was sufficient. There were no malperfusion events. Our results showed that transapical aortic cannulation was secure and useful for repair of acute type A aortic dissection.
