BACKGROUND: In November 2011, the FDA issued a Class I Recall of Riata(™) and Riata(™) ST ICD leads. Management recommendations regarding the recall have remained controversial.
OBJECTIVE: Data regarding the safety and feasibility of extraction of Riata(™) ICD leads are limited.
METHODS: We performed a retrospective study of patients undergoing extraction of Riata(™)/ST leads at 11 centers.
RESULTS: Between July 2003-April 2013, 577 Riata(™)/ST leads were extracted from 577 patients (Riata(™) 84%, Riata(™) ST 16%). Complete procedural success achieved in 99.1%. Cohort was 78% male with mean age 60 years and mean LVEF of 34±14%. Average implant duration was 44.7 months (range, 0-124.6). The majority of leads extracted were for infection (53.0%); 35.7% for lead malfunction. Evaluation for lead integrity was performed in 295 cases. Of these, 34.9% were found to have externalized cables. Implant duration was significantly longer in leads with externalized cables (p<0.0001). No difference in lead integrity was noted between Riata(™) and Riata(™) ST (11.7% v. 17.7% failure, p=0.23). Among leads in which cable externalization was noted, laser sheaths were employed more frequently (p=0.01). Major complications included 3 SVC/RV perforations requiring surgical intervention with one death 12 days post-procedure and 1 pericardial effusion requiring percutaneous drainage (0.87%).
CONCLUSION: Extraction of the Riata(™)/ST leads can be challenging and leads with externalized cables may require specific extraction techniques. Extraction of the Riata(™)/ST leads can be performed safely by experienced operators at high-volume centers with a complication rate comparable to published data.
