Abstract
Background: Traditional and leadless pacemaker (LPM) implantation are two options for patients with Sick Sinus Syndrome (SSS), a sinoatrial node dysfunction that leads to progressive symptoms if left untreated. Limited data exists to compare differences in procedural complications and hospital outcomes for these implants.
Methods: National Inpatient Sample 2018-2019 was used to compare outcomes between patients with SSS who underwent implantation of a traditional or LPM. Logistic regression was used to compare characteristics and in-hospital outcomes.
Results: Of 122,580 admissions for pacemaker placement, 5300 (4.3%) received a LPM vs. 117280 (95.7%) who received a traditional. These patients had greater LOS (8.1 days-vs-5.6 days), increased total cost ($174,990-vs-$117,225), and increased mortality (1.42-vs0.73%, p<0.001). LPM patients also experienced higher rates of complications such as cardiogenic shock (3.11-vs-2.1%, p<0.001), stroke (4.15-vs-2.11%, p<0.001), and ICU admission (7.92-vs-4.19%, p<0.001).
Conclusion: LPM had longer LOS, increased total cost and higher mortality signifying the underlying complexity of these patients. Traditional pacemaker implantation still appears to be the standard of care. LPM are most likely reserved for high risk patients with limited life expectancy and multiple comorbidities.
