Before and after surgery to correct Type A dissection

Type A Dissection is an emergency that requires rapid diagnosis and surgical intervention.

At NewYork-Presbyterian Hospital/Columbia University Medical Center (NYPH/Columbia), the Aortic Surgery Center provides immediate triage, direct transfer to the operating room, medical stabilization, and definitive repair with innovative procedures involving surgery, stents, and transcatheter valves.

NYPH/Columbia surgeons and cardiologists work as a multidisciplinary team to ensure excellent outcomes and 100% long-term follow up. When treating patients with type A dissection, antegrade selective perfusion is used to provide enhanced protection of the brain. Valve sparing root replacements may be performed to replace the entire ascending aorta without leaving residual dissection behind. The Center's operative mortality rate is less than 2%, compared to the national average of 15-20%.

If you suspect an aortic emergency, call the Aortic Emergency Hotline: 212.305.4980.
