The reason for CVAP was categorized by obstacle (focal occlusion, valve presence, small caliber vessel) and location. The number, type, and size of balloon used, inflation characteristics, complications, and success of lead deployment crossing the point of intervention were all tabulated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Seventy\u2010seven percent of patients (36\/47) had successful CVAP. The most common reason for intervention was a focal occlusion (24\/47; 51%), followed by valve presence (13\/47; 28%), and small vessel caliber (10\/47; 21%). Focal occlusions were most successfully managed with CVAP (23\/24; 96%), followed by small vessel caliber (7\/10; 70%) and valve presence (6\/13; 46%). The reason for failure was most commonly due to failure to relieve the obstruction (5\/11; 45%), thrombosis (3\/11; 27.3%), dissection (2\/11; 18.2%), and inability to pass the balloon through the occlusion (1\/11; 9.0%).
