Influence of hospital volume and outcomes of adult structural heart procedures

Figure 1 Effect of annual hospital volume on in-hospital mortality and procedural complication during transcatheter aortic valve repair. TAVR: Transcatheter aortic valve repair; OR: Odds ratio.

Figure 2 Effect of annual hospital volume on length of stay and cost of hospitalization in transcatheter aortic valve repair. TAVR: Transcatheter aortic valve repair.

Figure 3 Effect of annual hospital volume. A: On primary and secondary outcome during transcatheter mitral valve repair; B: On in-hospital mortality (primary outcome) during atrial septal defect/patent foramen ovale closure; C: On primary outcome, length of stay and cost of hospitalization during atrial septal defect/patent foramen ovale closure. ASD: Atrial septal defect; PFO: Patent foramen ovale; OR: Odds ratio.

Figure 4 Effect of annual hospital left atrial appendage closure volume (per unit increment) on primary outcome, length of stay and cost of hospitalization during left atrial appendage closure. LAA: Left atrial appendage.
