Abstract

The mechanical approach in the recanalization of total coronary occlusions consisted of the use of a new 0.014-inch standard coronary guide wire with jointless spring coil design that improves steering characteristics and tip stiffness. In addition, a 0.014-inch soft tip wire with hydrophilic coating and low-profile 1.5 mm over-the-wire balloons were used. The first wire was used selectively in 86 patients to treat 95 total occlusions, of which 51(54%) were older than 3 months. Unfavorable angiographic characteristics were present in 79 (83%) of 95 lesions. Overall crossing success was 71% (67 of 95 lesions). Complications were one coronary perforation with cardiac tamponade necessitating emergency bypass surgery. In conclusion, the mechanical approach with the use of the standard coronary guide wire with jointless spring coil design provides a high success rate in the recanalization of unfavorable total occlusions.
