Figure 1. Forest plot for relative risk ratios of any PVL for TTE-TAVI in comparison to TEE-TAVI with subgroups based on study type. TTE; transthoracic echocardiography; TEE: transesophageal echocardiography; RR: relative risk; CI: confidence interval; PVL: paravalvular leak; TAVI: transcatheter aortic valve implantation
