Background: An acute type A aortic dissection is considered a surgical emergency. Surgical mortality for acute type a aortic dissection reported in different experiences from single centers or surgeons varies from 7% to 30%. Early intervention and judicious management in type A dissection improve outcome in terms of mortality. This study was performed to analyse the surgical experience of acute type A aortic dissection from single centre.

Methods: 17 patients who were diagnosed with acute type A dissection were included in this study. These patients were admitted in GB Pant hospital from January 2016 to October 2018. Patients were evaluated with pulsed-wave Doppler echocardiography and cardiac CT angiography with 3D reconstruction and underwent surgery. Parameters under study were recorded and statistical analysis performed.

Results: The overall in-hospital mortality was 5.9%. Independent predictors of mortality were older age, previous history of hypertension, presence of previous aortic valve disease, presence of acute onset migrating chest pain and features of CHF, extent of dissection flap and type of surgery. Follow-up revealed significant improvement in NYHA status of patients postoperatively.

Conclusion: Timely intervention and prior comorbidities play an important role in determining surgical outcomes in patients with type A acute aortic dissection. Knowledge of significant risk-factors for operative mortality can contribute to better management. Shorter operative time and strict control of anticoagulation can lead to decreased mortality.
