Differences in cardiac output of patients undergoing trans-catheter aortic valve implantation according to their underlying rhythm

Figure 1 Study flow diagram. Flowchart showing the total number of patients screened (n = 496), exclusions (large annulus, aborted procedure, balloon valvuloplasty only, low ejection fraction or invalid measurements), and the final analytic cohort (n = 138), subdivided into atrial fibrillation (n = 31) and non-atrial fibrillation (n = 107) groups, and further by valve type (self-expanding valves = 59; balloon-expandable valve = 79). TAVI: Transcatheter aortic valve implantation; EF: Ejection fraction; AF: Atrial fibrillation; SEV: Self-expanding valves; BEV: Balloon-expandable valve.

Figure 2 Post-procedural cardiac output by valve type and atrial fibrillation status. A: Box plot comparing post-procedural cardiac output (L/minute) in patients with atrial fibrillation receiving either a balloon-expandable valve or a self-expanding valve; B: Box plot comparing post-procedural cardiac output (L/minute) in patients without atrial fibrillation receiving either a balloon-expandable valve or a self-expanding valve. BEV: Balloon-expandable valve; SEV: Self-expanding valve.
