**Goal**: To present surgical complications in a cohort of patients treated with transcatheter aortic valve implantation (TAVI) in a single institution. Complications were reported according to Valve Academic Research Consortium-2 (VARC-2) criteria. **Patients and Methods:** Since 11/2011 a total of 257 patients (139 male, 118 female) were treated with TAVI procedure. Average age was 78.6±7.3 years (30-91). Average Society of Thoracic Surgeons (STS) score was 5.4±3.8% (0.9-23.8). Self-expanding prosthesis was used in 98 and baloon expandable in 159 patients. Transfemoral approach was used in 243 (95%) of patients. Alternative access sites included transapical - 10, transaortic - 2 and subclavian - 2. **Results:** Overall mortality was 2.3% (6/257). Most frequent complications requiring surgical intervention included peripheral access site complications 17/243 (7%). Bleeding was observed in 9/257 (3.5%) with cardiac tamponade in 6/257 patients – 1 requiring subxiphoid drainage. Valvular embolization was observed in 4/257 patients (2%) with 1 requiring surgical intervention. Conversion to open sternotomy was required in 3/257 (1%) – 2 annular rupture, 1 apical rupture with 2/3 patients expiring. **Conclusion:** Complications of TAVI procedure that require surgical intervention are mostly related to vascular access site. Conversion to sternotomy is rare but yields a high mortality (1).
