Clinical impact of coronary protection during transcatheter aortic valve implantation: first reported series of patients
Key result
Pre-emptive left main protection during TAVI in high-risk patients was feasible, with left main compromise occurring in 20% (5 of 25) of cases, all successfully treated with emergency stenting.
Why the study?
Does pre-emptive left main protection improve safety and feasibility in patients at high risk of coronary obstruction during TAVI?

Structured PICO
Does pre-emptive left main protection improve safety and feasibility in patients at high risk of coronary obstruction during TAVI?
P
Population
25 patients undergoing TAVI who were at increased risk of left main compromise and received a pre-emptive left main protection technique.
E
Exposure
Pre-emptive left main (LM) protection technique using guidewires and an undeployed coronary balloon or stent positioned in the coronary artery during TAVI.
O
Outcome
Feasibility and safety of left main (LM) protection during TAVI.safety
Pre-emptive left main protection during TAVI is feasible and facilitates prompt treatment of coronary obstruction in high-risk patients.
Cite This Study
Abramowitz et al. (2015) conducted an observational in Increased risk of left main compromise during TAVI (n=25). Pre-emptive left main protection technique was evaluated on Left main compromise. Pre-emptive left main protection during TAVI in high-risk patients was feasible, with left main compromise occurring in 20% (5 of 25) of cases, all successfully treated with emergency stenting.
