Abstract
To utilize different retrograde techniques for the percutaneous coronary intervention (PCI) in chronic total occlusion (CTO). Retrograde PCI was performed after failure of the antegrade PCI, and techniques including retrograde wire crossing, kissing wire, retrograde balloon dilation, reverse controlled-antegrade-and-retrograde-subintimal-tracking (CART) were selectively applied in the PCI of two CTOs located in left anterior descending artery (LAD) and right coronary artery (RCA) respectively in two patients. Both CTOs were successfully re-opened and stented under the help of retrograde guidewires via the epicardial collaterals, and two significantly different techniques were finally adopted according to the characteristics of the collaterals and the lesions.
Key words: Chronic total occlusion (CTO), Percutaneous coronary intervention (PCI), Retrograde approach.
