Effects of percutaneous transluminal coronary angioplasty balloon compliance on angiographic and clinical outcomes

Influence of balloon design, plaque material composition, and balloon sizing on acute post angioplasty outcomes: An implicit finite element analysis

“…Lately, there has been some debate on what type of balloon material is optimal for PTA. Some retrospective observational studies suggest differences in angiographic results and overall procedural outcomes for different balloon materials 39 ; others do not 5,40 …”

“…Some retrospective observational studies suggest differences in angiographic results and overall procedural outcomes for different balloon materials 39 ; others do not. 5,40 This work focuses first on modeling the main balloon families covering most balloon designs used by clinicians during PTA. In what follows, and because they would be applied the same modeling method, both compliant and semicompliant balloons are considered belonging to the same category of semi-compliant balloons.…”

PTCA in angulated segments: Effects of balloon material, balloon length, and inflation sequence on straightening forces in an in vitro model

“…In three nonrandomized retrospective studies [6,8] and one randomized prospective study [9] of the relationship among balloon material, coronary dissection, and clinical complications, no significant difference between these variables was found. Raymenants and co-workers [ 101 recently reported a study of 1,650 patients in whom use of highly compliant balloons was associated with slightly lower dissection rate (17.4% vs. 19%) and significant reduction in the rate of clinical complications (4.2% vs. 8.1%).…”

The use of semi‐compliant versus non‐compliant balloon systems for predilatation during the implantation of self‐expandable transcatheter aortic valves

“… 5 Another concern with SCB systems is that their overexpansion in areas that lie proximally and distally to the actual stenotic target site could produce a higher degree of intimal injury or potential disruption in healthy surrounding areas, a hypothesis investigated by several studies that has ultimately not been proven definitively. 5 , 6 , 7 , 8 A similar analysis regarding the impact of balloon compliance during predilatation on the outcome of patients undergoing TAVR has not yet been undertaken, and the available data on the development and change of vessel stress gradients during SCB use is scarce. Other significant outcome and safety concerns that need to be investigated in greater detail include the potential of insufficient THV expansion due to incomplete valve dilatation due to the lower radial force exerted by SCBs during predilatation.…”
