Structural durability of early-generation Transcatheter aortic valve replacement valves compared with surgical aortic valve replacement valves in heart valve surgery: a systematic review and meta-analysis

  Fig. 1. PRISMA chart illustrating our process of obtaining the 13 included articles. Our initial search produced 396 studies and 1 study was retrieved from alternative sources. Out of this initial pool of studies, 193 remained after duplicates were removed. With 163 irrelevant records excluded based on their titles and abstracts, we reviewed the full texts of 30 articles, of which 17 were excluded and 13 remained for inclusion in our study

  Fig. 2. Forest plots of (a) 1-year (b) 2–3-year and (c) 5-year Paravalvular Regurgitation (Moderate or Severe). We observed higher rates of 1-year, 2–3-year and 5-year paravalvular regurgitation associated with the use of TAVR valves, as compared to SAVR valves

• 

  Fig. 3. Forest plots of (d) 1-year, (e) 2–3-year and (f) 5-year Moderate or Severe Aortic Regurgitation. We observed higher rates of 1-year, 2–3-year and 5-year moderate or severe aortic regurgitation associated with the use of TAVR valves, as compared to SAVR valves

• 

  Fig. 4. Forest plots of (g) 1-year, (h) 2–3-year and (i) 5-year Reintervention Rates. We observed higher rates of 1-year, 2–3-year and 5-year reintervention rates associated with the use of TAVR valves, as compared to SAVR valves

• 

  Fig. 5. Forest plots of (a) 1-year, (b) 2–3-year and (c) 5-year Endocarditis. We observed no statistical difference in 1-year, 2–3-year and 5-year endocarditis between TAVR and SAVR valves

• 

  Fig. 6. Forest plots of (d) 1-year, (e) 2–3-year and (f) 5-year All-cause Mortality. We observed no statistical difference in 1-year, 2–3-year and 5-year endocarditis between TAVR and SAVR valves

• 

  Fig. 7. Forest plots of (g) 1-year, (h) 2–3-year and (i) 5-year Mortality Due to Cardiovascular Reasons. We observed no statistical difference in 1-year, 2–3-year and 5-year endocarditis between TAVR and SAVR valves
