Data regarding outcomes for patients with severe aortic stenosis (AS) with concomitant aortic insufficiency (AI), undergoing transcatheter aortic valve replacement (TAVR) are limited. This study aimed to analyze the prevalence of severe AS with concomitant AI among patients undergoing TAVR and outcomes of TAVR in this patient group.Using data from the STS/ACC-TVT Registry, we identified patients with severe AS with or without concomitant AI who underwent TAVR between 2011 and 2016. Patients were categorized based on the severity of pre-procedural AI. Multivariable proportional hazards regression models were used to examine all-cause mortality and heart failure (HF) hospitalization at 1-year. Among 54,535 patients undergoing TAVR, 42,568 (78.1%) had severe AS with concomitant AI. Device success was lower in patients with severe AS with concomitant AI as compared with isolated AS. The presence of baseline AI was associated with lower 1 year mortality (HR 0.94 per 1 grade increase in AI severity; 95% CI, 0.91-0.98, P.001) and HF hospitalization (HR 0.87 per 1 grade increase in AI severity; 95% CI, 0.84-0.91, P.001).Severe AS with concomitant AI is common among patients undergoing TAVR, and is associated with lower 1 year mortality and HF hospitalization. Future studies are warranted to better understand the mechanisms underlying this benefit.In this nationally representative analysis from the United States, 78.1% of patients undergoing TAVR had severe AS with concomitant AI. Device success was lower in patients with severe AS with concomitant AI as compared with isolated AS. The presence of baseline AI was associated with lower 1 year mortality (HR 0.94 per 1 grade increase in AI severity; 95% CI, 0.91-0.98, P.001) and HF hospitalization (HR 0.87 per 1 grade increase in AI severity; 95% CI, 0.84-0.91, P.001).

Background Patients with diabetes mellitus (DM) experience higher rates of in-stent restenosis and greater benefit from drug-eluting stents implant at the time of percutaneous coronary intervention (PCI), necessitating prolonged dual anti-platelet therapy (DAPT). While DAPT reduces risk of ischemic events post-PCI, it also increases risk of bleeding. Whether bleeding rates differ among patients with and without DM, receiving long-term DAPT is unknown. Methods Among patients who underwent PCI and were maintained on DAPT for 1 year in a multicenter US registry, we assessed patient-reported bleeding over one year following PCI in patients with and without DM. Multivariable, hierarchical Poisson regression was used to evaluate the association of DM with bleeding during follow-up. Results Among 2334 PCI patients from 10 US hospitals (mean age 64, 54% ACS), 32.6% had DM. In unadjusted analyses, patients with DM had fewer bleeding events over the year following PCI (DM vs no DM: BARC=1: 78.0% vs 87.7%, P P = .33). Following adjustment, patients with (vs without DM) had a lower risk of BARC ≥1 bleeding during follow-up (relative risk [RR] 0.89, 95% CI 0.83–0.96). This decreased bleeding risk persisted after removing bruising from the endpoint definition. Conclusions In a real-world PCI registry, patients with DM experienced lower risk of bleeding risk on DAPT. As patients with DM also derive greater ischemic benefit from drug-eluting stents, which requires prolonged DAPT, our findings suggest that the balance between benefit and risk of this therapeutic approach may be even more favorable in patients with DM than previously considered.

Background The foundation of precision medicine is the ability to tailor therapy based upon the expected risks and benefits of treatment for each individual patient. In a prior study, we implemented a software platform, e PRISM, to execute validated risk-stratification models for patients undergoing percutaneous coronary intervention and found substantial variability in the use of the personalized estimates to tailor care. A better understanding of physicians' perspectives about the use of individualized risk-estimates is needed to overcome barriers to their adoption. Methods In a qualitative research study, we conducted interviews, in-person or by telephone, with 27 physicians at 8 centers that used e PRISM until thematic saturation occurred. Data were coded using descriptive content analyses. Results Three major themes emerged among physicians who did not use e PRISM to support decision making: (1) "Experience versus Evidence," physicians' preference to rely upon personal experience and subjective assessments rather than objective risk estimates; (2) "Omission of Therapy," the perception that the use of risk models leads to unacceptable omission of potentially beneficial therapy; and (3) "Unnecessary Information," the opinion that information derived from risk models is not needed because physicians' decision making is already sound and they already know the information. Conclusions Barriers to the use of risk models in clinical practice include physicians' perceptions that their experience is sufficient, that models may lead to omission of therapy in patients that may benefit from therapy, and that they already provide good care. Anticipating and overcoming these barriers may improve the adoption of precision medicine.

Drug-eluting stents (DES) reduce restenosis, as compared with bare-metal stents (BMS); however, the relationship between stent type and health status is unknown. We examined whether stent type was associated with health status outcomes in patients undergoing percutaneous coronary intervention (PCI).We evaluated 6- and 12-month health status in 2,694 patients with acute myocardial infarction (AMI) enrolled in the TRIUMPH and PREMIER registries who underwent PCI with DES (n = 1,361) or BMS (n = 1,333). Health status was assessed with the Seattle Angina Questionnaire, Medical Outcomes Study Short Form-12, and Patient Health Questionnaire depression scale. Propensity matching was performed to account for baseline differences in patient characteristics, resulting in a comparison cohort of 784 patients treated with DES and 784 patients treated with BMS. Both groups experienced significant improvements in health status at 6 and 12 months after PCI. Drug-eluting stent use was associated with a small improvement in Seattle Angina Questionnaire quality of life and functional limitation scores at 6 months (3.6 [95% CI 0.96-6.21], P = .007, and 3.8 [1.55-6.01], P.001, respectively), but not at 12 months (2.3 [-0.46 to 5.03], P = .10, and 0.3 [-2.04 to 2.48], P = .85, respectively).In patients with AMI undergoing PCI, DES use was associated with transient but unsustained health status benefits over 12 months after AMI.

Background While the process of informed consent is designed to transfer knowledge of the risks and benefits of treatment and to engage patients in shared medical decision-making, this is poorly done in routine clinical care. We assessed the impact of a novel informed consent form for percutaneous coronary intervention (PCI) that is more simply written, includes images of the procedure, and embeds individualized estimates of outcomes on multiple domains of successful informed consent and shared decision-making. Methods We interviewed 590 PCI patients receiving traditional consent documents and 527 patients receiving novel ePRISM consents at 9 US centers and compared patients’ perceptions, knowledge transfer, and engagement in medical decision-making. Heterogeneity across sites was assessed and adjusted for using hierarchical models. Results Site-adjusted analyses revealed more frequent review (72% for ePRISM vs 45% for original consents) and better understanding of the ePRISM consents (ORs = 1.8-3.0, depending upon the outcome) with marked heterogeneity across sites (median relative difference [MRD] in the ORs of ePRISM’s effect =2-3.2). Patients receiving ePRISM consents better understood the purposes and risks of the procedure (ORs = 1.9-3.9, MRDs = 1.1-6.2), engaged more in shared decision-making (proportional OR = 2.1 [95% CI = 1.02-4.4], MRD = 2.2) and discussed stent options with their physicians (58% vs. 31%; site-adjusted odds ratio = 2.7 [95% CI = 1.2, 6.3], MRD = 2.6) more often. Conclusions A personalized consent document improved the process of informed consent and shared decision-making. Marked heterogeneity across hospitals highlights that consent documents are but one aspect of engaging patients in understanding and participating in treatment.
