Journal Article
Challenges of coronary angiography and intervention in patients previously treated by TAVI
2015
Overview
Objective
Since the beginning of the transcatheter aortic valve implantation (TAVI) era, many prosthetic valves have entered clinical practice. TAVI prostheses differ regarding stent design and some may potentially interfere with diagnostic or interventional catheters. The aim of our analysis was to evaluate the feasibility of coronary angiography (CA) or percutaneous coronary intervention (PCI) in patients with prior TAVI.
Methods
From 2011 to 2014, 1,000 patients were treated by TAVI at our center using eight different valve prostheses (Symetis ACURATE TA and ACURATE TF; Medtronic CoreValve and Engager; JenaValve, SJM Portico; Edwards Lifesciences SAPIEN and SAPIEN XT). In this analysis, all patients were included who underwent either CA or PCI after TAVI. CA or PCI were rated as fully feasible when coronary ostia could be fully intubated, partially feasible when coronary arteries could be displayed only unselectively or unfeasible when coronary arteries could not be displayed.
Results
A total of 35 patients underwent CA/PCI after TAVI at our hospital. In all patients with valves implanted in a subcoronary position (SAPIEN

= 1), selective intubation was feasible using standard catheters. Out of 15 patients with valve types that are placed over the coronary ostia (CoreValve

= 1), selective intubation of coronary arteries was not possible in 9 cases, even with the use of different diagnostic catheters. Full accessibility was possible only in 3 cases. In 2 cases, display of the right CA was only feasible using unselective aortography. In 1 case, coronary arteries could not be displayed at all immediately after a valve-in-valve procedure.
Conclusion
CA or PCI after TAVI is usually feasible. Devices that are placed in a partially supracoronary position, however, can interfere with diagnostic or guiding catheters and impede straightforward intervention, especially when the prosthesis is not implanted in the correct position.
