PURPOSE: @entity177 ( @entity177 ) is frequent in @entity1 eligible for cardiac resynchronization therapy (CRT) and may be worsened by the use of contrast agents. We sought to determine the feasibility of CRT implantation without contrast injection in @entity1 with contraindication to @entity1496 . METHODS: @entity1 eligible for CRT and presenting with @entity177 were prospectively included (non-contrast NC group). A contemporary control group (CG) of CRT @entity1 with contrast injection was used for comparison. An over-the-wire coronary sinus (CS) lead with an angled distal tip was selected for this "blind harpooning" technique. RESULTS: Seventeen @entity1 in the NC group were included (78        7  years). Serum @entity1011 was 208        86   mol/L (glomerular filtration rate 33        15  mL/ @entity1009 .73  m(2)). CG included 25 @entity1 (70        7  years, serum @entity1011 85        21   mol/L). CRT implantation was successful in 16/17 @entity1 (94.1  %) without contrast injection. The mean procedure and fluoroscopy times were similar in the two groups: 146        29 in the NC group versus 153        25  min (p   =   0.57) and 25        12 in the NC group versus 23        16  min (p   =   0.7) respectively. The mean CS lead implantation time was 36        19 (NC group) versus 39        15  min (p   =   0.64). No major procedure-related complications were observed in both groups. CONCLUSION: CRT implantation is feasible in the majority of the cases (94.1  %) without contrast injection and without lengthening the procedure time in @entity1 with @entity177 .
