RESUMO
Aortic stenosis (AS) is a serious and complex condition, for which optimal management continues to evolve rapidly. An understanding of current clinical practice guidelines is critical to effective patient care and shared decision-making. This state of the art review of the 2021 European Society of Cardiology/European Association for Cardio-Thoracic Surgery Guidelines and 2020 American College of Cardiology/American Heart Association Guidelines compares their recommendations for AS based on the evidence to date. The European and American guidelines were generally congruent with the exception of three key distinctions. First, the European guidelines recommend intervening at a left ventricular ejection fraction of 55%, compared with 60% over serial imaging by the American guidelines for asymptomatic patients. Second, the European guidelines recommend a threshold of ≥65 years for surgical bioprosthesis, whereas the American guidelines employ multiple age categories, providing latitude for patient factors and preferences. Third, the guidelines endorse different age cut-offs for transcatheter vs. surgical aortic valve replacement, despite limited evidence. This review also discusses trends indicating a decreasing proportion of mechanical valve replacements. Finally, the review identifies gaps in the literature for areas including transcatheter aortic valve implantation in asymptomatic patients, the appropriateness of Ross procedures, concomitant coronary revascularization with aortic valve replacement, and bicuspid AS. To summarize, this state of the art review compares the latest European and American guidelines on the management of AS to highlight three areas of divergence: timing of intervention, valve selection, and surgical vs. transcatheter aortic valve replacement criteria.

In October 2021, the European Society of Cardiology (ESC) and the European Association for Cardio-Thoracic Surgery (EACTS) jointly agreed to establish a Task Force (TF) to review recommendations of the 2018 ESC/EACTS Guidelines on myocardial revascularization as they apply to patients with left main (LM) disease with low-to-intermediate SYNTAX score (0-32). This followed the withdrawal of support by the EACTS in 2019 for the recommendations about the management of LM disease of the previous guideline. The TF was asked to review all new relevant data since the 2018 guidelines including updated aggregated data from the four randomized trials comparing percutaneous coronary intervention (PCI) with drug-eluting stents vs. coronary artery bypass grafting (CABG) in patients with LM disease. This document represents a summary of the work of the TF; suggested updated recommendations for the choice of revascularization modality in patients undergoing myocardial revascularization for LM disease are included. In stable patients with an indication for revascularization for LM disease, with coronary anatomy suitable for both procedures and a low predicted surgical mortality, the TF concludes that both treatment options are clinically reasonable based on patient preference, available expertise, and local operator volumes. The suggested recommendations for revascularization with CABG are Class I, Level of Evidence A. The recommendations for PCI are Class IIa, Level of Evidence A. The TF recognized several important gaps in knowledge related to revascularization in patients with LM disease and recognizes that aggregated data from the four randomized trials were still only large enough to exclude large differences in mortality.

AIM: The aim of this study was to compare long-term all-cause mortality between patients receiving percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) using multiple (MAG) or single arterial grafting (SAG). METHODS AND RESULTS: The current study is a post hoc analysis of the SYNTAX Extended Survival Study, which compared PCI with CABG in patients with three-vessel (3VD) and/or left main coronary artery disease (LMCAD) and evaluated survival with ≥10 years of follow-up. The primary endpoint was all-cause mortality at maximum follow-up (median 11.9 years) assessed in the as-treated population. Of the 1743 patients, 901 (51.7%) underwent PCI, 532 (30.5%) received SAG, and 310 (17.8%) had MAG. At maximum follow-up, all-cause death occurred in 305 (33.9%), 175 (32.9%), and 70 (22.6%) patients in the PCI, SAG, and MAG groups, respectively (P < 0.001). Multiple arterial grafting [adjusted hazard ratio (HR) 0.66, 95% confidence interval (CI) 0.49-0.89], but not SAG (adjusted HR 0.83, 95% CI 0.67-1.03), was associated with significantly lower all-cause mortality compared with PCI. In patients with 3VD, both MAG (adjusted HR 0.55, 95% CI 0.37-0.81) and SAG (adjusted HR 0.68, 95% CI 0.50-0.91) were associated with significantly lower mortality than PCI, whereas in LMCAD patients, no significant differences between PCI and MAG (adjusted HR 0.90, 95% CI 0.56-1.46) or SAG (adjusted HR 1.11, 95% CI 0.81-1.53) were observed. In patients with revascularization of all three major myocardial territories, a positive correlation was observed between the number of myocardial territories receiving arterial grafts and survival (Ptrend = 0.003). CONCLUSION: Our findings suggest that MAG might be the more desirable configuration for CABG to achieve lower long-term all-cause mortality than PCI in patients with 3VD and/or LMCAD.

BACKGROUND: Ten-year all-cause death according to incomplete (IR) versus complete revascularization (CR) has not been fully investigated in patients with 3-vessel disease and left main coronary artery disease undergoing percutaneous coronary intervention (PCI) versus coronary artery bypass grafting (CABG). METHODS: The SYNTAX Extended Survival study (Synergy Between PCI With TAXUS and Cardiac Surgery: SYNTAX Extended Survival [SYNTAXES]) evaluated vital status up to 10 years in patients who were originally enrolled in the SYNTAX trial. In the present substudy, outcomes of the CABG CR group were compared with the CABG IR, PCI CR, and PCI IR groups. In addition, in the PCI cohort, the residual SYNTAX score (rSS) was used to quantify the extent of IR and to assess its association with fatal late outcome. The rSS of 0 suggests CR, whereas a rSS>0 identifies the degree of IR. RESULTS: IR was more frequently observed in patients with PCI versus CABG (56.6% versus 36.8%) and more common in those with 3-vessel disease than left main coronary artery disease in both the PCI arm (58.5% versus 53.8%) and the CABG arm (42.8% versus 27.5%). Patients undergoing PCI with CR had no significant difference in 10-year all-cause death compared with those undergoing CABG (22.2% for PCI with CR versus 24.3% for CABG with IR versus 23.8% for CABG with CR). In contrast, those with PCI and IR had a significantly higher risk of all-cause death at 10 years compared with CABG and CR (33.5% versus 23.7%; adjusted hazard ratio, 1.48 [95% CI, 1.15-1.91]). When patients with PCI were stratified according to the rSS, those with a rSS≤8 had no significant difference in all-cause death at 10 years as the other terciles (22.2% for rSS=0 versus 23.9% for rSS>0-4 versus 28.9% for rSS>4-8), whereas a rSS>8 had a significantly higher risk of 10-year all-cause death than those undergoing PCI with CR (50.1% versus 22.2%; adjusted hazard ratio, 3.40 [95% CI, 2.13-5.43]). CONCLUSIONS: IR is common after PCI, and the degree of incompleteness was associated with 10-year mortality. If it is unlikely that complete (or nearly complete; rSS<8) revascularization can be achieved with PCI in patients with 3-vessel disease, CABG should be considered.

OBJECTIVES: The present study aimed to identify significant causes of readmission within 30 days following coronary artery bypass graft (CABG) surgery and compare readmission incidence related to surgical site infections (SSIs) before and after implementing international recommendations for antibiotic prophylaxis. METHODS: We analyzed 2,225 CABG patients who received either guideline-directed antibiotic prophylaxis (GDAP = 568) or institutional antibiotic prophylaxis (non-GDAP = 1,657) between January 2017 and December 2019. The primary outcome was a composite of sternal wound infection (SWI) or harvest SWI. Secondary outcomes consisted of the individual components of composite end point, the incidence of in-hospital SSIs, and prolonged postoperative length of hospital stay (LOS) (>7 days). Propensity matching was used to select pairs for final comparison. RESULTS: Before implementing GDAP, the most frequent reason for readmission were SSIs, causing 58.2% of all readmissions within 30 days. Of 429 matched pairs, 48 patients in the GDAP group and 67 patients in the non-GDAP group were readmitted to a hospital within 30 days for any cause (11.2 vs. 15.6%, p = 0.048). We found a decreased readmission incidence for reasons related to SSIs, although these differences did not reach statistical significance (7.4 vs. 10.0%, p = 0.069). Adherence to GDAP was associated with reduced in-hospital risks of SSIs and prolonged postoperative LOS (19.6 vs. 26.6%, p = 0.015). CONCLUSIONS: In this contemporary clinical practice study, the adherence to GDAP was an insufficient measure to decrease rehospitalization due to SSIs. The present findings warrant further investigation on factors that may contribute to SSIs development after hospital discharge.

BACKGROUND: The Synergy between PCI with Taxus and Cardiac Surgery (SYNTAX) trial was a non-inferiority trial that compared percutaneous coronary intervention (PCI) using first-generation paclitaxel-eluting stents with coronary artery bypass grafting (CABG) in patients with de-novo three-vessel and left main coronary artery disease, and reported results up to 5 years. We now report 10-year all-cause death results. METHODS: The SYNTAX Extended Survival (SYNTAXES) study is an investigator-driven extension of follow-up of a multicentre, randomised controlled trial done in 85 hospitals across 18 North American and European countries. Patients with de-novo three-vessel and left main coronary artery disease were randomly assigned (1:1) to the PCI group or CABG group. Patients with a history of PCI or CABG, acute myocardial infarction, or an indication for concomitant cardiac surgery were excluded. The primary endpoint of the SYNTAXES study was 10-year all-cause death, which was assessed according to the intention-to-treat principle. Prespecified subgroup analyses were performed according to the presence or absence of left main coronary artery disease and diabetes, and according to coronary complexity defined by core laboratory SYNTAX score tertiles. This study is registered with ClinicalTrials.gov, NCT03417050. FINDINGS: From March, 2005, to April, 2007, 1800 patients were randomly assigned to the PCI (n=903) or CABG (n=897) group. Vital status information at 10 years was complete for 841 (93%) patients in the PCI group and 848 (95%) patients in the CABG group. At 10 years, 248 (28%) patients had died after PCI and 212 (24%) after CABG (hazard ratio 1·19 [95% CI 0·99-1·43], p=0·066). Among patients with three-vessel disease, 153 (28%) of 546 had died after PCI versus 114 (21%) of 549 after CABG (hazard ratio 1·42 [95% CI 1·11-1·81]), and among patients with left main coronary artery disease, 95 (27%) of 357 had died after PCI versus 98 (28%) of 348 after CABG (0·92 [0·69-1·22], pinteraction=0·023). There was no treatment-by-subgroup interaction with diabetes (pinteraction=0·60) and no linear trend across SYNTAX score tertiles (ptrend=0·20). INTERPRETATION: At 10 years, no significant difference existed in all-cause death between PCI using first-generation paclitaxel-eluting stents and CABG. However, CABG provided a significant survival benefit in patients with three-vessel disease, but not in patients with left main coronary artery disease.

Pregnant patients with Marfan syndrome (MFS) are at high risk of developing aortic dissection or rupture during the third trimester and early postpartum period. This increased likelihood is the consequence of the hyperdynamic and hypervolemic cardiocirculatory state and/or pregnancy-mediated structural changes of the arterial wall in response to hemodynamic and hormonal changes. In this article, we report on the case of a 26-year-old pregnant woman with MFS in the 30th gestation week, who presented with type A aortic dissection at the emergency department. According to the multidisciplinary team decision, an urgent cesarean section was performed, followed by the Bentall procedure. The patient was discharged on the 10th postoperative day, and her premature child was discharged 6 weeks after birth.

BACKGROUND: Numerous randomised trials have compared coronary artery bypass grafting (CABG) with percutaneous coronary intervention (PCI) for patients with coronary artery disease. However, no studies have been powered to detect a difference in mortality between the revascularisation strategies. METHODS: We did a systematic review up to July 19, 2017, to identify randomised clinical trials comparing CABG with PCI using stents. Eligible studies included patients with multivessel or left main coronary artery disease who did not present with acute myocardial infarction, did PCI with stents (bare-metal or drug-eluting), and had more than 1 year of follow-up for all-cause mortality. In a collaborative, pooled analysis of individual patient data from the identified trials, we estimated all-cause mortality up to 5 years using Kaplan-Meier analyses and compared PCI with CABG using a random-effects Cox proportional-hazards model stratified by trial. Consistency of treatment effect was explored in subgroup analyses, with subgroups defined according to baseline clinical and anatomical characteristics. FINDINGS: We included 11 randomised trials involving 11â518 patients selected by heart teams who were assigned to PCI (n=5753) or to CABG (n=5765). 976 patients died over a mean follow-up of 3·8 years (SD 1·4). Mean Synergy between PCI with Taxus and Cardiac Surgery (SYNTAX) score was 26·0 (SD 9·5), with 1798 (22·1%) of 8138 patients having a SYNTAX score of 33 or higher. 5 year all-cause mortality was 11·2% after PCI and 9·2% after CABG (hazard ratio [HR] 1·20, 95% CI 1·06-1·37; p=0·0038). 5 year all-cause mortality was significantly different between the interventions in patients with multivessel disease (11·5% after PCI vs 8·9% after CABG; HR 1·28, 95% CI 1·09-1·49; p=0·0019), including in those with diabetes (15·5% vs 10·0%; 1·48, 1·19-1·84; p=0·0004), but not in those without diabetes (8·7% vs 8·0%; 1·08, 0·86-1·36; p=0·49). SYNTAX score had a significant effect on the difference between the interventions in multivessel disease. 5 year all-cause mortality was similar between the interventions in patients with left main disease (10·7% after PCI vs 10·5% after CABG; 1·07, 0·87-1·33; p=0·52), regardless of diabetes status and SYNTAX score. INTERPRETATION: CABG had a mortality benefit over PCI in patients with multivessel disease, particularly those with diabetes and higher coronary complexity. No benefit for CABG over PCI was seen in patients with left main disease. Longer follow-up is needed to better define mortality differences between the revascularisation strategies. FUNDING: None.

BACKGROUND AND AIMS: The purpose of this prospective randomized study was to compare the early and midterm outcomes of aortic valve replacement (AVR) through upper ministernotomy with conventional AVR through median sternotomy. METHODS: One hundred patients undergoing elective AVR were randomized into two groups: the M group (upper ministernotomy group, n = 50) and the C group (conventional sternotomy group, n = 50). The operative data, major adverse outcomes, and postoperative variables were compared between the two groups of patients. A cross-sectional follow-up was performed 24.9 ± 5.8 months after surgery. RESULTS: The aortic cross-clamp time and cardiopulmonary bypass time were significantly longer in the M group. Similar incidences of major cardiac, neurologic and renal complications were recorded in both groups. Two patients (4%) in the C group developed wound infections. The length of ICU stay was similar in both groups. The patients in the M group had a shorter hospital stay compared with the patients in the C group (7.6 ± 2 days vs 9.3 ± 4.8 days; P = 0.022). Follow-up revealed that the time period needed to reach full recovery was significantly shorter in the ministernotomy group (1.7 ± 1.2 months vs 2.8 ± 1.6 months; P = 0.001). Morbidity and mortality data did not differ between the two groups. CONCLUSIONS: There was no difference in the major outcomes between the patients who underwent upper ministernotomy and those who underwent full sternotomy. The benefits of the minimally invasive approach were the shorter hospital stay and significantly faster recovery of patients after discharge from the hospital.

Aims: The number of transcatheter aortic valve implantation (TAVI) procedures is rapidly increasing. This has a major impact on health care resource planning. However, the annual numbers of TAVI candidates per country are unknown. The aim of this study was to estimate current and future number of annual TAVI candidates in 27 European countries, the USA and Canada. Methods and results: Systematic literature searches and meta-analyses were performed on aortic stenosis (AS) epidemiology and decision-making in severe symptomatic AS. The incidence rate of severe AS was determined. Findings were combined with population statistics and integrated into a model employing Monte Carlo simulations to predict the annual number of TAVI candidates. Various future scenarios and sensitivity analyses were explored. Data from 37 studies (n = 26 402) informed the model. The calculated incidence rate of severe AS was 4.4/year [95% confidence interval (95% CI) 3.0-6.1] in patients ≥65 years. AS-related symptoms were present in 68.3% (95% CI 60.8-75.9%) of patients with severe AS. Despite having severe symptomatic AS, 41.6% (95% CI 36.9-46.3%) did not undergo surgical aortic valve replacement. Of the non-operated patients, 61.7% (95% CI 42.0-81.7%) received TAVI. The model predicted 114 757 (95% CI 69 380-172 799) European and 58 556 (95% CI 35 631-87 738) Northern-American TAVI candidates annually. Conclusion: Currently, approximately 180 000 patients can be considered potential TAVI candidates in the European Union and in Northern-America annually. This number might increase up to 270 000 if indications for TAVI expand to low-risk patients. These findings have major implications for health care resource planning in the 29 individual countries.

Coronary artery bypass grafting remains one of the most commonly performed major surgeries, with well-established symptomatic and prognostic benefits in patients with multivessel and left main coronary artery disease. This review summarizes current indications, contemporary practice, and outcomes of coronary artery bypass grafting. Despite an increasingly higher-risk profile of patients, outcomes have significantly improved over time, with significant reductions in operative mortality and perioperative complications. Five- and 10-year survival rates are ≈85% to 95% and 75%, respectively. A number of technical advances could further improve short- and long-term outcomes after coronary artery bypass grafting. Developments in off-pump and no-touch procedures; epiaortic scanning; conduit selection, including bilateral internal mammary artery and radial artery use; intraoperative graft assessment; minimally invasive procedures, including robotic-assisted surgery; and hybrid coronary revascularization are discussed.

OBJECTIVES: The aim of this study was to identify methodological variations leading to varied recommendations between the American College of Cardiology (ACC)/American Heart Association (AHA) and the European Society of Cardiology (ESC)/European Association for Cardio-Thoracic Surgery (EACTS) valvular heart disease guidelines and to suggest foundational steps towards standardizing guideline development. METHODS: An in-depth analysis was conducted to evaluate the methodologies used in developing the transatlantic guidelines for managing valvular heart disease. The evaluation was benchmarked against the standards proposed by the Institute of Medicine. RESULTS: Substantial discrepancies were noted in the methodologies utilized in development processes, including Writing Committee composition, evidence evaluation, conflict of interest management and voting processes. Furthermore, despite their mutual differences, both methodologies demonstrate notable deviations from the Institute of Medicine standards in several essential areas, including literature review and evidence grading. These dual variances likely influenced divergent treatment recommendations. For example, the ESC/EACTS recommends transcatheter edge-to-edge repair for patients with chronic severe mitral regurgitation ineligible for mitral valve surgery, while the ACC/AHA recommends transcatheter edge-to-edge repair based on anatomy, regardless of surgical risk. ESC/EACTS guidelines recommend a mechanical aortic prosthesis for patients under 60, while ACC/AHA guidelines recommend it for patients under 50. Notably, the ACC/AHA and ESC/EACTS guidelines have differing age cut-offs for surgical over transcatheter aortic valve replacement (<65 and <75 years, respectively). CONCLUSIONS: Variations in methodologies for developing clinical practice guidelines have resulted in different treatment recommendations that may significantly impact global practice patterns. Standardization of essential processes is vital to increase the uniformity and credibility of clinical practice guidelines, ultimately improving healthcare quality, reducing variability and enhancing trust in modern medicine.
