Abstract

Background: Advancements in transcatheter tricuspid valve interventions (TTVI) have surged exponentially in recent years. Methods We queried the national Inpatient sample (NIS) database and included data between Jan 1, 2011 and Dec 31, 2020. The primary objective was to characterize the trends in utilization of TTVI, surgical tricuspid valve repair (STVr) and replacement (STVR). The secondary objective of the study was to analyze the in-hospital outcomes associated with each type of intervention. A propensity score was calculated for all hospitalizations and unmatched hospitalizations were excluded from the outcome analysis. Results A total of 98,202 TV interventions were identified. Of these, 1,830 (1.9%) constituted TTVI, 76,747 (78.2%) STVr and 19,625 (19.9%) STVR. Over the study period, the total number of TV interventions exhibited an exponential increase with STVRʼs proportion relative to all interventions declining by 2020 (Figure 1A). STVR accounted for the highest proportion of TV procedure-related deaths overall, followed by STVr, and lastly, TTVI (Figure 1B). STVr and STVR were associated with increased inpatient mortality (7% vs 2.4%, 11.6% vs 2.3%, respectively), circulatory shock (24.0% vs 11.8%, 25.7% vs 13.6%) and respiratory failure (10.8% vs 1.5%, 12.4% vs 1.9%, p<0.001) when compared to TTVI (p <0.001). Conclusion TTVI are increasing in practice. Compared to surgical TV interventions, TTVI have improved in hospital mortality, circulatory shock and respiratory failure. [Formula presented]
