Background: Tricuspid regurgitation (TR) poses a significant health burden, with severe disease linked to poor long-term outcomes, including intractable right heart failure. Despite guidelines advocating intervention, surgical options have historically been limited due to high mortality rates. Advancements in transcatheter valve interventions (TTVI) have renewed interest in less invasive treatments.

Methods: Utilizing data from the National Inpatient Sample (NIS) spanning 2011 to 2020, this study analyzed trends, factors influencing procedure selection, and outcomes of surgical and transcatheter tricuspid valve interventions across the United States. The analysis included 98,202 interventions, examining demographic and clinical disparities among patients undergoing TTVI, surgical tricuspid valve repair (STVr), and surgical tricuspid valve replacement (STVR).

Results: Between 2011 and 2020, 98,202 TV interventions were analyzed. Over time, total TV interventions increased, with TTVI peaking in 2020 (4.8 %). STVr declined from 78.20 % (2011) to 76.80 % (2020), while STVR decreased from 21.80 % to 18.40 %. Factors influencing procedure selection included age, race, hospital size, teaching status, and comorbidities. STVR accounted for the highest proportion of TV procedure-related deaths, followed by STVr and TTVI. STVR-related deaths declined over time, while STVr-related deaths increased.

Conclusion: This study provides a helpful visual representation of mortality trends and can inform healthcare professionals about the changing landscape of TV procedure outcomes. Further analysis would be necessary to understand the underlying causes of these trends, such as changes in patient demographics, procedural volume, technology, and clinical practices over time.

Background: Limited data exist on the risk profile and prognosis of young patients undergoing percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS). This study sheds light on the burden of cardiovascular risk factors and outcomes in this population.

Methods: The Houston Methodist Young ACS-PCI registry is a retrospective analysis of young adults (18 to 50 years) undergoing PCI for ACS between 2010 and 2022. Outcomes of interest were major adverse cardiovascular events (MACE: all-cause mortality, myocardial infarction (MI), ischemic stroke) at one year.

Results: Among 629 patients (median age, 46 years, 23.5% women, and 65.3% White adults), 69.2% had Non-ST-Segment Elevation MI. A total of 22.7% had prior MI, 26.2% prior PCI, and 9.2% had prior coronary artery bypass graft surgery. The prevalence of active smoking, dyslipidemia, hypertension, and diabetes was 69.4%, 82.2%, 80.4%, and 39.6%, respectively. Age-adjusted diabetes rates increased over time, while dyslipidemia, hypertension, and obesity rates remained unchanged. The femoral artery was the most common arterial access (85.2%), 72.7% had one vessel disease, 44.3% had the left anterior descending artery as the culprit vessel, and 78.5% of patients received one stent. At a median of 3.8 years, all-cause mortality was 28 deaths per 1000 person-years. At one year, 11.4% experienced MACE; racial and ethnic minority (Black, Hispanic, and Others), dialysis, prior MI, and stent diameter were independent predictors of MACE.

Conclusions: The study highlights a notable burden of cardiovascular risk factors and cardiovascular outcomes in young adults with ACS undergoing PCI, underscoring the need for strategies to enhance risk assessment and guide interventions among young adults.

Background: Coronary artery disease (CAD) in diabetes mellitus (DM) is a significant cause of mortality among US adults. This study investigates trends in CAD-related mortality in adults aged 25 and older with DM, focusing on geographic, gender, and racial/ethnic disparities from 1999 to 2020.

Methods: A retrospective analysis was conducted using death certificate data from the CDC WONDER database from 1999 to 2020. Age-adjusted mortality rates (AAMRs), annual percent change (APC), and average annual percentage change (AAPC) were calculated per 100,000 persons, stratified by year, sex, race/ethnicity, and geographical region.

Results: CAD in DM accounted for 1,462,279 deaths among US adults aged 25+. Most deaths occurred in medical facilities (44.2 %) and at home (29.3 %). The overall AAMR for CAD in DM-related deaths decreased from 36.3 in 1999 to 31.7 in 2020, with an AAPC of -0.96 (95 % CI: -1.29 to -0.77, p < 0.000001). Men had higher AAMRs (41.6) compared to women (22.6), with a more significant decrease in women (AAPC: -2.10, p < 0.000001) than in men (AAPC: -0.34, p = 0.001200). Racial/ethnic disparities showed the highest AAMRs in American Indians/Alaska Natives (43.6), followed by Blacks (37.8), Hispanics (33.8), Whites (29.7), and Asians/Pacific Islanders (22.5). The most significant decrease was in Hispanics (AAPC: -1.64, p < 0.000001). Geographically, AAMRs ranged from 13.7 in Nevada to 51.3 in West Virginia, with the highest mortality observed in the Midwest (AAMR: 34.5). Nonmetropolitan areas exhibited higher AAMRs (35.2) than metropolitan areas (29.7), with a more pronounced decrease in metropolitan areas (AAPC: -1.22, p < 0.000001) compared to nonmetropolitan areas (AAPC: -0.03, p = 0.854629).

Conclusion: The notable increase in mortality rates associated with CAD among patients with DM from 2018 to 2020 presents a substantial concern that necessitates targeted public health interventions to ensure equitable access to cardiovascular care.

Background: Complex Revascularisation in High-Risk Indicated Patients (CHIP) is emerging in Percutaneous Coronary Intervention (PCI). We document the frequency and outcomes following CHIP PCI in the Australian population, to understand risk and guide clinical decision-making. We propose a scoring system to define CHIP procedures.

Methods: Patients undergoing PCI from Melbourne Intervention Group registry between 2005 and 2018 were analysed. Patients were stratified based on the number of high-risk features defined as 1)presence of ≥3 patient factors including age > 75yo, COPD, diabetes, renal impairment (eGFR<60 mL/min/1.73 m2), PVD, and 2)LVEF<30 %, and/or 3)having one complex coronary anatomical feature such as LMCA PCI, ACC/AHA B2/C lesion PCI, presence of multi-vessel disease or CTO PCI. National Death Index linkage was performed for long-term mortality analysis. Outcomes were analysed according to 4 risk categories - low risk(score 0), intermediate risk(score 1), high-risk(score 2), and very high-risk(score 3).

Results: 20,973patients were analysed. Majority of patients underwent intermediate-risk procedures(71.7 %), with low rates of high-risk(6.6 %), and very high-risk(0.2 %). Lesion success inversely correlates with risk; low-risk(99.4 %), intermediate-risk(95.1 %), high-risk(94.3 %), very high-risk(92.5 %),p < 0.001. In-hospital and 30-day death correlates with risk; low-risk(0.0 %/0.1 %), intermediate-risk(0.3 %/0.5 %), high-risk(1.5 %/2.9 %), very high-risk(2.4 %/7.1 %),p < 0.001. Long-term mortality correlates with risk; low-risk(12.3 %), intermediate-risk(15.8 %), high-risk(49.3 %), very high-risk(76.2 %),p < 0.001. On multivariate analysis, increasing risk correlates with long-term mortality; intermediate-risk(HR1.41), high-risk(HR6.42), and very high-risk(14.05).

Conclusion: In the Australian practice, proportion of patients undergoing high and very high-risk PCI procedures are low. Despite good procedural success and in-hospital outcomes, long-term mortality is poor. Further research into appropriate patient selection, and direct comparison of CHIP PCI to those treated medically and surgically should be considered.

Background: Data on Absorb bioresorbable vascular scaffold (BVS) use in patients presenting with ST-segment elevation myocardial infarction (STEMI) are limited. Furthermore, Absorb studies including STEMI patients lacked a prespecified implantation technique to optimize BVS deployment. This study examines the 5-year outcomes of BVS in STEMI patients using an optimized implantation strategy and the impact of prolonged dual antiplatelet therapy (DAPT).

Methods: The BVS STEMI STRATEGY-IT study is a prospective, non-randomized, single-arm multicenter trial (NCT02601781). It involved 505 STEMI patients undergoing primary percutaneous coronary intervention with a predefined BVS implantation protocol. Key endpoints were a 5-year device-oriented composite endpoint (DOCE) of cardiac death, target-vessel myocardial infarction (TV-MI), and ischemia-driven target lesion revascularization (ID-TLR). The study also compared outcomes based on DAPT duration (36 months vs. shorter).

Results: 502 (99.4 %) patients completed the 5-year follow-up. DOCE rate was 2.4 %. ID-TLR, TV-MI, and cardiac death rates were 1.6 %, 0.8 %, and 0.6 %, respectively. No DOCE occurred between three and five years. Scaffold thrombosis (ScT) was 1 %, all occurring within 24 months. Longer-term DAPT significantly reduced DOCE (1.3 % vs. 4.3 %; HR: 0.29; 95 % CI: 0.1-0.9; p = 0.03) driven by a lower rate of TV-MI (0 % vs. 2.2 %; p = 0.018) compared to shorter-term DAPT, as well as ScT (0 % vs 2.7 %, p = 0.007).

Conclusions: This study shows favorable 5-year outcomes for BVS in selected STEMI patients with an optimized implantation strategy. Prolonged DAPT further improved outcomes, emphasizing its role in reducing adverse events during scaffold resorption. Further research is needed to assess newer-generation bioresorbable devices.
