For devices classified as cardiac ablation percutaneous catheters, we found that there was a statistically significant drop in reported malfunctions from 2019-20 to 2020-21. On average, there were ~1.6 fewer weekly reports of malfunctions attributed to cardiac ablation percutaneous catheters during the pandemic compared to the pre-pandemic year, a drop of 19% (P-value = 0.04) (Figure 1). We additionally examined the number of weekly reports of injuries attributed to cardiac ablation percutaneous catheters in the pandemic year versus the pre-pandemic year, and found no significant difference (P-value ≈ 0.42). We then examined adverse event data for cardiac ablation percutaneous catheters for atrial fibrillation. We found that there were, on average, ~1.8 fewer weekly reports of malfunctions attributed to cardiac ablation percutaneous catheters for atrial fibrillation during the pandemic compared to the pre-pandemic year, a drop of 23% (P-value < 0.02) (Figure 2). We further examined the number of weekly reports of injuries attributed to cardiac ablation percutaneous catheters for atrial fibrillation in the pandemic year versus the pre-pandemic year, and found no significant difference (P-value ≈ 0.61) (Figure 3) . Finally, we analyzed adverse event data for cardiac ablation percutaneous catheters for atrial flutter. We found that there were, on average, ~1.1 fewer weekly reports of injuries attributed to cardiac ablation percutaneous catheters for atrial flutter in the pandemic year compared to the pre-pandemic year, a drop of 25% (P-value < 0.02). We analyzed the number of weekly reports of malfunctions attributed to cardiac ablation percutaneous catheters for atrial flutter in the pandemic year versus the pre-pandemic year, and found no significant difference (P-value ≈ 0.10).
