Ultrasound Guided Technique for Percutaneous Transfemoral Transcatheter Aortic Valve Implantation

Ultrasound- Versus Fluoroscopy-Guided Strategy for Transfemoral Transcatheter Aortic Valve Replacement Access: A Systematic Review and Meta-Analysis

“… 6 , 7 , 16 , 17 , 19 , 21 Data was available from full texts in 6 studies, 6 , 7 , 14 , 17 , 19 , 21 from a research letter in one study 18 and from an abstract in one study. 16 As the full text for the study by Bouteau et al 14 , 15 was only available as a thesis in French, it was translated into English before data extraction. Since the study by Potluri et al 19 did not report sufficient data to ascertain access site related bleeding complications, bleeding outcomes were taken from Basra et al 20 ; a study from the same center and authors with an overlapping study time periods that provided sufficient data to adjudicate bleeding events as access site related.…”

“… 7 , 18 Using the Risk of Bias in Nonrandomised Studies of Interventions tool, we identified 4 studies at moderate risk of bias 7 , 17 , 18 , 21 and 4 at serious risk of bias (Table II in the Data Supplement ). 6 , 14 , 16 , 19 The driver of serious and moderate risk of bias in all cases was adjustment for confounders. One study only adjusted for Society of Thoracic Surgeons score.…”

“… 6 , 7 , 14 , 17 – 19 , 21 Crude major access site vascular complications were reported in 8 studies and occurred in 5.5% (211/3864) of patients. 6 , 7 , 14 , 16 – 19 , 21 Minor access site vascular complications were ascertained in 7 studies and occurred in 6.6% (244/3710) of patients. 6 , 7 , 14 , 17 – 19 , 21 …”

“…Eight observational studies were considered eligible (Figure 1), collectively consisting of 3875 participants (median, 458; range, 154-1171). 6,7,[14][15][16][17][18][19][20][21] Seven of the included studies (n=3488) were published between 2019 and 2020, 7,[15][16][17][18][19]21 and at least 7 (n=3043) included contemporary generation valve types. 6,7,16,17,19,21 Data was available from full texts in 6 studies, 6,7,14,17,19,21 from a research letter in one study 18 and from an abstract in one study.…”
