ICD IMPLANTATION <9 MONTHS FROM THE INITIAL DIAGNOSIS OF NONISCHEMIC CARDIOMYOPATHY
| Recommended |
| "1.In patients <9 months from the initial diagnosis of NICM who require nonelective permanent pacing, who would meet primary prevention criteria for implanta- tion of an ICD, and recovery of left ventricular function is uncertain or not expected, implantation of an ICD with the appropriately selected pacing abilities is recommended." |
| "2. In patients <9 months from the initial diagnosis of NICM with sustained (or hemodynamically significant) ventricular tachyarrhythmia, implantation of an ICD is recommended." |
| Can be Useful |
|
"1. If recovery of left ventricular function is unlikely, implantation of an ICD for primary prevention can be useful between 3 and 9 months after initial diagnosis of NICM." |
|
"2.In patients <9 months from the initial diagnosis of NICM with syncope that is thought to be due to a ven- tricular tachyarrhythmia (by clinical history or docu- mented NSVT), implantation of an ICD can be useful." |
|
"3. In patients <9 months from the initial diagnosis of NICM who have been listed for heart transplant or implanted with a left ventricular assist device, implantation of an ICD can be useful." |
| Not Recommended |
|
"1. Implantation of an ICD for primary prevention is not recommended within the first 3 months after initial diagnosis of NICM." |
