Effect of gradual computerized angioplasty on outcomes of patients undergoing coronary stenting.

Mechanical trauma caused by percutaneous coronary intervention is a major factor contributing to subsequent cardiac events, restenosis, and the need for target lesion revascularization (TLR). To minimize this trauma, we developed a Computerized Angioplasty Pressure Sensor and Inflator Device (CAPSID) for gradual inflation. The objective of the present prospective randomized study was to examine whether the use of this novel device reduced TLR, as well as cardiac events, in patients undergoing stenting.

Computerized gradual balloon inflation: a novel strategy of coronary angioplasty superior to a standard manual approach.

Background: Mechanical trauma caused by PCI is a primary reason for restenosis and subsequent target lesion revascularization (TLR). To minimize this trauma, we developed a computerized angioplasty pressure sensor and inflator device (CAPSID) for gradual inflation. The objective of this prospective randomized study was to examine whether use of CAPSID reduces early and late cardiac events in patients undergoing PCI.
