Transcatheter aortic valve replacement- management of patients with significant coronary artery disease undergoing aortic valve interventions: surgical compared to catheter-based approaches in hybrid procedures.

ABSTRACT:

Background

Coronary artery disease (CAD) is associated with poorer outcomes after aortic valve replacement (AVR). For high-risk patients with complex CAD, combined transcatheter aortic valve replacement (TAVR) plus off-pump/minimally-invasive coronary artery bypass (OPCAB/MIDCAB) has been proposed.

Methods

A prospective registry analysis was performed to compare the characteristics and outcomes of patients undergoing TAVR+OP/MIDCAB with those undergoing TAVR plus percutaneous coronary intervention (PCI) and surgical AVR plus coronary artery bypass grafting (CABG) between 2008 and 2015 at a single site in Germany.

Results

464 patients underwent SAVR+CABG, 50 underwent TAVR+OP/MIDCAB, and 112 underwent TAVR+PCI. The mean ages (p < 0.001) and logistic EuroSCOREs (p < 0.001) were similarly higher in TAVR+OP/MIDCAB and TAVR+PCI patients compared to SAVR+CABG patients. Prior cardiac surgery was more common in TAVR+PCI than in TAVR+OP/MIDCAB and SAVR+CABG patients (p < 0.001). Procedural times were shortest (p < 0.001), creatine kinase (muscle brain) levels least elevated (p < 0.001), pericardial tamponade least common (p = 0.027), and length of hospital stay shortest (p = 0.011) in TAVR+PCI, followed by TAVR+OP/MIDCAB and SAVR+CABG patients. In-hospital mortality was highest for TAVR+OP/MIDCAB patients (18.0%) with comparable rates for TAVR+PCI and SAVR+CABG groups (9.0 and 6.9%; p = 0.009). Mortality by 12 months was more probable after TAVR+OP/MIDCAB (HR: 2.17, p = 0.002) and TAVR/PCI (HR: 1.63, p = 0.010) than after SAVR+CABG, with the same true of rehospitalisation (HR: 2.39, p = 0.003 and HR: 1.63, p = 0.033).

Conclusions

TAVR+OP/MIDCAB patients share many characteristics with TAVR+PCI patients, with only slightly poorer long-term outcomes. In patients ineligible for SAVR+CABG and TAVR+PCI, hybrid interventions are reasonable second-line options.

Project description:BackgroundCardiohepatic syndrome (CHS) has been identified as an important but underrecognized survival predictor in multiple cardiovascular disease entities. The objectives of this study were to evaluate the prevalence and prognostic value of CHS in patients undergoing TAVR for severe aortic stenosis (AS).MethodsThe study included patients with available laboratory parameters of hepatic function who underwent TAVR from July 2013 until December 2019 at our center. CHS was defined as an elevation of at least two of three laboratory cholestasis parameters above the upper limit of normal (bilirubin, alkaline phosphatase, and gamma glutamyl transferase). Study endpoints were three-year survival, technical and device failure (VARC 3), as well as New York Heart Association (NYHA) functional class at follow-up.ResultsAmong a total of 953 analyzed patients (47.6% females, median age 80.0 [76.0-85.0] years) CHS was present in 212 patients (22.4%). In patients with vs. without CHS, rates of technical (6.1% vs. 8.4%, p = 0.29) and device failure (18.9% vs. 17.3%, p = 0.59) were comparable. NYHA functional class at baseline and follow-up was more severe in patients with CHS. Nevertheless, heart failure symptoms improved from baseline to follow-up irrespective of hepatic function. Three-year survival rates were significantly lower in patients with CHS (49.4 vs. 65.4%, p < 0.001). The predictive value of CHS persisted after adjustment in a multivariable analysis (hazard ratio 1.58, p < 0.01).ConclusionIn patients undergoing TAVR, CHS is prevalent in 22% of patients and is associated with increased postinterventional mortality. Thus, CHS should be included in the decision-making process within the TAVR heart team. Cardiohepatic syndrome (CHS) as defined by an elevation of at least two of three laboratory cholestasis parameters above the upper limit of normal was prevalent in 22% of patients undergoing TAVR for severe AS. The presence of CHS was associated with more severe heart failure symptoms and worse three-year survival.

Project description:BackgroundElevated levels of lipoprotein(a) (Lp[a]) have been recognized as substantial risk factors for cardiovascular disease and aortic stenosis (AS). However, the specific role of Lp(a) in promoting aortic valve calcification (AVC) and influencing mortality in elderly, multimorbid patients undergoing transcatheter aortic valve replacement (TAVR) remains unclear and warrants further investigation.MethodsA retrospective analysis was conducted on all consecutive patients who underwent TAVR between August 2019 and June 2020 at our clinic. Patients with missing data or prior aortic valve replacement were excluded. The study cohort was stratified based on an Lp(a) threshold of 60 mg/dl according to guidelines for lipoprotein apheresis in UK and Germany.1,2 RESULTS: In total, 454 patients were included into the analysis. Mean age was 81 ± 6 years and patients presented with a notable cardiovascular risk profile. Lp(a) values ≥ 60 mg/dl were detected in 102 (22.5%) patients, while 352 (77.5%) had Lp(a) values < 60 mg/dl. The median calcium volume of the total cohort was 894.5 [570.8; 1,382.8] mm2. No significant difference was observed between the groups (p = 0.83). Furthermore, Lp(a) did not emerge as a statistically significant predictor of calcium levels before TAVR. Notably, male gender (B = 404.11, p < 0.001) and mean trans-valvular pressure gradient (B = 15.64, p < 0.001) were identified as the strongest coefficients within the robust regression analysis. Log-rank tests indicated no prognostic utility of Lp(a) for 30-day all-cause mortality (p = 0.30) or 40 months long-term all-cause mortality (p = 0.60).ConclusionLp(a) might not exert a significant effect on calcification levels or all-cause mortality in patients undergoing TAVR. Despite the study's highly selected population, these results align with current research, supporting the assumption that the influence of Lp(a) may be confined to the early stages of AS and its progression.
