Percutaneous Aortic Valve Replacement for Critical Aortic Stenosis: A Single-Center Experience

Özet

Introduction: This study aimed to assess the procedural success and early term outcomes of percutaneous aortic valve replacement in patients with critical aortic stenosis. Methods: This study included patients with severe high-risk aortic stenosis who underwent transcatheter aortic valve replacement between November 2014 and June 2016. All patients underwent transesophageal echocardiography and cardiac tomography prior to the procedure. The Edwards Sapien XT balloon-expandable transcatheter aortic valve was used in all patients. The valve size was selected according to measurements obtained from cardiac tomography and transesophageal echocardiography. Patients were evaluated for procedural success and adverse effects during hospitalization and a 30-day follow-up period. Results: This study included a total of 33 patients (18 males, 15 females) with a median age of 78.2 (range: 62–92) years. Valve implantation was successfully performed in all patients. The valve size, which was selected according to transesophageal echocardiography, was increased in only one patient following cardiac tomography. Three patients died during the hospitalization period. No further deaths occurred during the 30-day observation period. Discussion and Conclusion: Percutaneous transaortic valve replacement treatment for patients with high-risk aortic stenosis is an efficient and reliable treatment modality. Transesophageal echocardiography is a complementary and irreplaceable element for cardiac tomography when determining the valve size and operation strategy.
