Stable complex coronary artery disease can be treated with coronary artery bypass grafting (CABG), percutaneous coronary intervention (PCI), or medical therapy. Multidisciplinary decision-making has ...gained more emphasis over the recent years to select the most optimal treatment strategy for individual patients with stable complex coronary artery disease. However, the so-called 'Heart Team' concept has not been widely implemented. Yet, decision-making has shown to remain suboptimal; there is large variability in PCI-to-CABG ratios, which may predominantly be the consequence of physician-related factors that have raised concerns regarding overuse, underuse, and inappropriate selection of revascularization. In this review, we summarize these and additional data to support the statement that a multidisciplinary Heart Team consisting of at least a clinical/non-invasive cardiologist, interventional cardiologist, and cardiac surgeon, can together better analyse and interpret the available diagnostic evidence, put into context the clinical condition of the patient as well as consider individual preference and local expertise, and through shared decision-making with the patient can arrive at a most optimal joint treatment strategy recommendation for patients with stable complex coronary artery disease. In addition, other aspects of Heart Team decision-making are discussed: the organization and logistics, involvement of physicians, patients, and assisting personnel, the need for validation, and its limitations.
The aim of this study was to examine the relation between institutional experience and procedural results of transcatheter mitral valve repair.
Transcatheter mitral valve repair for the treatment of ...mitral regurgitation (MR) is a complex procedure requiring navigation of the left atrium, left ventricle, and mitral valve apparatus using echocardiographic guidance.
MitraClip procedures from the Society of Thoracic Surgeons/American College of Cardiology TVT (Transcatheter Valve Therapy) Registry were stratified into tertiles on the basis of site-specific case sequence (1 to 18, 19 to 51, and 52 to 482). In-hospital outcomes of procedural success, procedural time, and procedural complications were examined. To evaluate the learning curve for the procedure, generalized linear mixed models were developed using case sequence number as a continuous variable.
MitraClip procedures (n = 12,334) performed at 275 sites between November 2013 and September 2017 were analyzed. Optimal procedural success (≤1+ residual MR without mortality or need for cardiac surgery) increased across tertiles of case experience (62.0%, 65.5%, and 72.5%; p < 0.001), whereas procedural time and procedural complications decreased. Acceptable procedural success (≤2+ residual MR without death or need for cardiac surgery) also increased across tertiles of case experience, but the differences were smaller (91.2%, 91.2%; and 92.9%; p = 0.006). In the learning-curve analysis, visual inflection points for procedural time, procedural success, and procedural complications were evident after about 50 cases, with continued improvements observed up to 200 cases.
For transcatheter mitral valve repair with the MitraClip, increasing institutional experience was associated with improvements in procedural success, procedure time, and procedural complications. The impact of institutional experience was larger when considering the goal of achieving optimal MR reduction.
There are no data available on specific causes of death from randomized trials that have compared coronary artery bypass grafting (CABG) with percutaneous coronary intervention (PCI).
The purpose of ...this study was to investigate specific causes of death, and its predictors, after revascularization for complex coronary disease in patients.
An independent Clinical Events Committee consisting of expert physicians who were blinded to the study treatment subclassified causes of death as cardiovascular (cardiac and vascular), noncardiovascular, or undetermined according to the trial protocol. Cardiac deaths were classified as sudden cardiac, related to myocardial infarction (MI), and other cardiac deaths.
In the randomized cohort, there were 97 deaths after CABG and 123 deaths after PCI during a 5-year follow-up. After CABG, 49.4% of deaths were cardiovascular, with the greatest cause being heart failure, arrhythmia, or other causes (24.6%), whereas after PCI, the majority of deaths were cardiovascular (67.5%) and as a result of MI (29.3%). The cumulative incidence rates of all-cause death were not significantly different between CABG and PCI (11.4% vs. 13.9%, respectively; p = 0.10), whereas there were significant differences in terms of cardiovascular (5.8% vs. 9.6%, respectively; p = 0.008) and cardiac death (5.3% vs. 9.0%, respectively; p = 0.003), which were caused primarily by a reduction in MI-related death with CABG compared with PCI (0.4% vs. 4.1%, respectively; p <0.0001). Treatment with PCI versus CABG was an independent predictor of cardiac death (hazard ratio: 1.55; 95% confidence interval: 1.09 to 2.33; p = 0.045). The difference in MI-related death was seen largely in patients with diabetes, 3-vessel disease, or high SYNTAX (TAXUS Drug-Eluting Stent Versus Coronary Artery Bypass Surgery for the Treatment of Narrowed Arteries) trial scores.
During a 5-year follow-up, CABG in comparison with PCI was associated with a significantly reduced rate of MI-related death, which was the leading cause of death after PCI. Treatments following PCI should target reducing post-revascularization spontaneous MI. Furthermore, secondary preventive medication remains essential in reducing events post-revascularization.

This study sought to report the largest series of patients receiving a surgical reoperation after transcatheter aortic valve replacement (TAVR) using the Society of Thoracic Surgeons (STS) Adult ...Cardiac Surgery Database.
TAVR has become an effective means of treating aortic stenosis. As TAVR is used in progressively lower-risk cohorts, management of device failure will become increasingly important.
The STS Adult Cardiac Surgery Database was queried for patients with a history of prior TAVR undergoing surgical aortic valve replacement from 2011 to 2015. Observed-to-expected (O/E) mortality ratios were determined to facilitate comparison across reoperative indications and timing from index TAVR procedure.
A total of 123 patients met inclusion criteria (median age 77 years) with an STS Predicted Risk of Mortality of 4%, 4% to 8%, and >8% in 17%, 24%, and 59%, respectively. Median time to reoperation was 2.5 (interquartile range: 0.7 to 13.0) months, and the operative mortality rate was 17.1%. Common indications for reoperation included early TAVR device failures such as paravalvular leak (15%), structural prosthetic deterioration (11%), failed repair (11%), sizing or position issues (11%), and prosthetic valve endocarditis (10%). All pre-operative risk categories were associated with an increased O/E mortality ratio (Predicted Risk of Mortality <4%: O/E 5.5; 4% to 8%: O/E 1.7; >8%: O/E 1.2).
SAVR following early failure of TAVR, while rare, is associated with worse-than-expected outcomes as compared with similar patients initially undergoing SAVR. Continued experience with this developing technology is needed to reduce the incidence of early TAVR failure and further define optimal treatment of failed TAVR prostheses.
There is a significant demand for devices that can rapidly detect chemical-biological-explosive (CBE) threats on-site and allow for immediate responders to mitigate spread, risk, and loss. The key to ...an effective reconnaissance mission is a unified detection technology that analyzes potential threats in real time. In addition to reviewing the current state of the art in the field, this review illustrates the practicality of colorimetric arrays composed of sensors that change colors in the presence of analytes. This review also describes an outlook toward future technologies, and describes how they could possibly be used in areas such as war zones to detect and identify hazardous substances.
OBJECTIVE
To assess whether incomplete revascularization by percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) has an effect on long-term outcomes.
METHODS
During a ...heart team discussion to evaluate whether patients were eligible for randomization in the SYNTAX trial, both the cardiologist and surgeon agreed on which vessels needed revascularization. This statement was compared with the actual revascularization after treatment. Incomplete revascularization was defined as when a preoperatively identified vessel with a lesion was not revascularized. Outcomes were major adverse cardiac or cerebrovascular events (MACCE), the composite safety endpoint of death/stroke/myocardial infarction (MI), and individual MACCE components death, MI and repeat revascularization at 3 years. Predictors of incomplete revascularization were explored.
RESULTS
Incomplete revascularization was found in 43.3% (388/896) PCI and 36.8% (320/870) CABG patients. Patients with complete revascularization by PCI had lower rates of MACCE (66.5 versus 76.2%, P < 0.001), the composite safety endpoint (83.4 versus 87.9%, P = 0.05) and repeat revascularization (75.5 versus 83.9%, P < 0.001), but not death and MI. In the CABG group, no difference in outcomes was seen between incomplete and complete revascularization groups. Incomplete revascularization was identified as independent predictor of MACCE in PCI (HR = 1.55, 95% CI 1.15-2.08, P = 0.004) but not CABG patients. Independent predictors of incomplete revascularization by PCI were hyperlipidaemia (OR = 1.59, 95% CI 1.04-2.42, P = 0.031), a total occlusion (OR = 2.46, 95% CI 1.66-3.64, P < 0.001) and the number of vessels (OR = 1.58, 95% CI 1.41-1.77, P < 0.001). Independent predictors of incomplete revascularization by CABG were unstable angina (OR = 1.42, 95% CI 1.02-1.98, P = 0.038), diffuse disease or narrowed ( < 2 mm) segment distal to the lesion (OR = 1.87, 95% CI 1.31-2.69, P = 0.001) and the number of vessels (OR = 1.70, 95% CI 1.53-1.89, P < 0.001).
CONCLUSIONS
Despite the hypothesis-generating nature of this data, this study demonstrates that incomplete revascularization is associated with adverse events during follow-up after PCI but not CABG.
This study sought to evaluate racial disparities in the performance and outcomes of transcatheter aortic valve replacement (TAVR).
Racial disparities in cardiovascular diseases are well described. ...Whether the racial disparities observed in surgical aortic valve replacement also exist with TAVR remains unknown.
Patients undergoing TAVR between November 2011 and June 2016 were identified in the American College of Cardiology/Society of Thoracic Surgeons/Transcatheter Valve Therapy Registry. We described the racial distribution, and the risk-adjusted in-hospital morbidity, and mortality stratified by race. We evaluated 1-year outcomes in a subset of patients via linkage to Medicare (Centers for Medicare and Medicaid Services) claims.
Among the 70,221 included patients, 91.3% were white, 3.8% were black, 3.4% were Hispanic, and 1.5% were of Asian/Native American/Pacific Islander race. This represented significant underrepresentation of nonwhite patients compared with their proportion of the population. After risk-adjustment, there was no difference in the rates of in-hospital mortality, myocardial infarction, stroke, major bleeding, vascular complications, or new pacemaker requirements among the 4 racial groups. Among 29,351 patients with Centers for Medicare and Medicaid Services linkage, 1-year adjusted mortality rates were similar in blacks and Hispanics compared with whites, but lower among patients of Asian/Native American/Pacific Islander race (adjusted hazard ratio: 0.71; 95% confidence interval: 0.55 to 0.92; p = 0.028). Black and Hispanic patients had more heart failure hospitalizations compared with whites (adjusted hazard ratio: 1.39; 95% confidence interval: 1.16 to 1.67; p < 0.001; and adjusted hazard ratio: 1.37; 95% confidence interval: 1.13 to 1.66; p = 0.004, respectively). These differences persisted after additional risk-adjustment for socioeconomic status.
Racial minorities are underrepresented among patients undergoing TAVR in the United States, but their adjusted 30-day and 1-year clinical outcomes are comparable with those of white race.

The benefit of optimal medical therapy (OMT) on 5-year outcomes in patients with 3-vessel disease and/or left main disease after percutaneous coronary intervention or coronary artery bypass grafting ...(CABG) was demonstrated in the randomized SYNTAX (Synergy Between PCI With Taxus and Cardiac Surgery) trial.
The objective of this analysis is to assess the impact of the status of OMT at 5 years on 10-year mortality after percutaneous coronary intervention or CABG.
This is a subanalysis of the SYNTAXES (Synergy Between PCI With Taxus and Cardiac Surgery Extended Survival) study, which evaluated for up to 10 years the vital status of patients who were originally enrolled in the SYNTAX trial. OMT was defined as the combination of 4 types of medications: at least 1 antiplatelet drug, statin, angiotensin-converting enzyme inhibitor/angiotensin receptor blocker, and beta-blocker. After stratifying participants by the number of individual OMT agents at 5 years and randomized treatment, a landmark analysis was conducted to assess the association between treatment response and 10-year mortality.
In 1,472 patients, patients on OMT at 5 years had a significantly lower mortality at 10 years compared with those on ≤2 types of medications (13.1% vs 19.9%; adjusted HR: 0.470; 95% CI: 0.292-0.757; P = 0.002) but had a mortality similar to those on 3 types of medications. Furthermore, patients undergoing CABG with the individual OMT agents, antiplatelet drug and statin, at 5 years had lower 10-year mortality than those without.
In patients with 3-vessel and/or left main disease undergoing percutaneous coronary intervention or CABG, medication status at 5 years had a significant impact on 10-year mortality. Patients on OMT with guideline-recommended pharmacologic therapy at 5 years had a survival benefit.
