Impact of Age on the Relationship between Cross-Clamp Time and Mortality in Cardiac Surgery.

Age is an independent risk factor for mortality even when all known comorbidities are considered. Thus, other factors may additionally contribute to the age-associated risk. We performed a systematic literature search and identified 161 manuscripts, of which 32 studies (18,256 patients) were analyzed. Cross-clamp time correlated with observed mortality. The increase in mortality risk with cross-clamp time was much greater in older patients than in younger patients. The log odds ratio (OR) for age and cross-clamp time was 0.07 and 0.01, respectively, which was highly significant for both independent risk factors. Age accelerates the increase in mortality risk with increasing aortic cross-clamp times.

Off-Pump Reduces Risk of Coronary Bypass Grafting in Patients with High MELD-XI Score.

BACKGROUND: This study aimed to assess the influence of the model of end-stage liver disease without International Normalized Ratio (INR) (MELD-XI) score on outcomes after elective coronary artery bypass surgery (CABG) without (Off-Pump) or with (On-Pump) cardiopulmonary bypass. METHODS: We calculated MELD-XI (5.11 × ln serum bilirubin + 11.76 × ln serum creatinine in + 9.44) for 3,535 consecutive patients having undergone elective CABG between 2009 and 2020. A MELD-XI threshold was determined using the Youden Index based on receiver operating characteristics. Propensity score matching and logistic regression was performed to identify risk factors for inhospital mortality and Major Adverse Cardiac and Cerebrovascular Event (MACCE). RESULTS: Patients were 68 ± 10 years old (76% male). Average MELD-XI was 10.9 ± 3.25. The MELD-XI threshold was 11. Patients below this threshold had somewhat lower EuroSCORE II than those above (3.5 ± 4 vs. 4.1 ± 4.7, p < 0.01), but mortality was almost four times higher above the threshold (below 1.5% vs. above 6.2%, p < 0.001). Two-thirds of patients received Off-Pump CABG. There was a trend towards higher risk in Off-Pump patients. Mortality was numerically but not statistically different to On-Pump below the MELD XI threshold (1.3 vs. 2.2%, p = 0.34) and was significantly lower above the threshold (4.9 vs. 8.9%, p < 0.02). Off-Pump above the threshold was also associated with less low-output syndrome and fewer strokes. Equalizing baseline differences by propensity matching verified the significant mortality difference above the threshold. Multivariable regression analysis revealed MELD-XI, On-Pump, atrial fibrillation, and the De Ritis quotient (Aspartate aminotransferase (ASAT)/Alanine Aminotransferase (ALAT)) as independent predictors of mortality. CONCLUSION: Elective CABG patients with elevated MELD-XI scores are at increased risk for perioperative mortality and morbidity. This risk can be significantly mitigated by performing CABG Off-Pump.

Cardiac Surgery 2023 Reviewed.

We reviewed the cardiac surgical literature for 2023. PubMed displayed almost 34,000 hits for the search term "cardiac surgery AND 2023." We used a PRISMA approach for a results-oriented summary. Key manuscripts addressed the mid- and long-term effects of invasive treatment options in patient populations with coronary artery disease (CAD), comparing interventional therapy (percutaneous coronary intervention [PCI]) with surgery (coronary artery bypass graft [CABG]). The literature in 2023 again confirmed the excellent long-term outcomes of CABG compared with PCI in patients with left main stenosis, specifically in anatomically complex chronic CAD, but even in elderly patients, generating further support for an infarct-preventative effect as a prognostic mechanism of CABG. For aortic stenosis, a previous trend of an early advantage for transcatheter (transcatheter aortic valve implantation [TAVI]) and a later advantage for surgical (surgical aortic valve replacement) treatment was also re-confirmed by many studies. Only the Evolut Low Risk trial maintained an early advantage of TAVI over 4 years. In the mitral and tricuspid field, the number of interventional publications increased tremendously. A pattern emerges that clinical benefits are associated with repair quality, making residual regurgitation not irrelevant. While surgery is more invasive, it currently generates the highest repair rates and longest durability. For terminal heart failure treatment, donor pool expansion for transplantation and reducing adverse events in assist device therapy were issues in 2023. Finally, the aortic diameter related to adverse events and technical aspects of surgery dominated in aortic surgery. This article summarizes publications perceived as important by us. It cannot be complete nor free of individual interpretation, but provides up-to-date information for patient-specific decision-making.

Coronary Artery Bypass Grafting versus Percutaneous Coronary Intervention in Patients with Chronic Total Occlusion.

OBJECTIVES: Mechanisms of coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) differ as CABG provides surgical collateralization and may prolong life by preventing future myocardial infarctions (MIs). However, evidence for CABG in patients with chronic total occlusion (CTO) has not been fully elucidated and the impact of PCI is discussed controversially. METHODS: We performed a meta-analysis of studies comparing outcomes in patients with/without multivessel disease undergoing CABG or PCI for CTO. The primary outcome was long-term all-cause mortality (≥5 years). Secondary outcomes were MIs, repeat revascularization, cardiac mortality, major adverse cardiovascular events, and stroke, as well as short-term mortality (30 days/in-hospital) and stroke. A pooled Kaplan-Meier survival curve after reconstruction analysis was generated. Random-effects models were used. RESULTS: Six studies totaling 12,504 patients were included. In the pooled Kaplan-Meier analysis, PCI showed a significantly higher risk of death in the follow-up compared with CABG (hazard ratio [HR]: 2.12, 95% confidence interval [CI]: 1.88-2.38, p < 0.01). During the observation period, PCI was also associated with higher rates of MI (odds ratio [OR]: 2.86, 95% CI: 1.82-4.48, p < 0.01) and more repeat revascularization (OR: 4.88, 95% CI: 1.99-11.91, p = 0.0005). The other outcomes did not show significant differences. CONCLUSION: CABG is associated with superior survival to PCI over time in patients with CTO who are eligible for both PCI and CABG. This survival advantage is associated with fewer events of MI and repeat revascularization.

Extracorporeal life support after surgical repair for acute type a aortic dissection: A systematic review and meta-analysis.

BACKGROUND: The use of extracorporeal life support (ECLS) in patients after surgical repair for acute type A aortic dissection (ATAAD) has not been well documented. METHODS: We performed a systematic review and meta-analysis to assess the outcomes of ECLS after surgery for ATAAD with data published by October 2023 in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) and the Meta-analysis of Observational Studies in Epidemiology (MOOSE) reporting guidelines. The protocol was registered in PROSPERO (CRD42023479955). RESULTS: Twelve observational studies met our eligibility criteria, including 280 patients. Mean age was 55.0 years and women represented 25.3% of the overall population. Although the mean preoperative left ventricle ejection fraction was 59.8%, 60.8% of patients developed left ventricle failure and 34.0% developed biventricular failure. Coronary involvement and malperfusion were found in 37.1% and 25.6%, respectively. Concomitant coronary bypass surgery was performed in 38.5% of patients. Regarding ECLS, retrograde flow (femoral) was present in 39.9% and central cannulation was present in 35.4%. In-hospital mortality was 62.8% and pooled estimate of successful weaning was 50.8%. Neurological complications, bleeding and renal failure were found in 25.9%, 38.7%, and 65.5%, respectively. CONCLUSION: ECLS after surgical repair for ATAAD remains associated with high rates of in-hospital death and complications, but it still represents a chance of survival in critical situations. ECLS remains a salvage attempt and surgeons should not try to avoid ECLS at all costs after repairing an ATAAD case.

Cardiac Surgery 2022 Reviewed.

PubMed displayed almost 37,000 hits for the search term "cardiac surgery AND 2022." As before, we used the PRISMA approach and selected relevant publications for a results-oriented summary. We focused on coronary and conventional valve surgery, their overlap with interventional alternatives, and briefly assessed surgery for aorta or terminal heart failure. In the field of coronary artery disease (CAD), key manuscripts addressed prognostic implications of invasive treatment options, classically compared modern interventions (percutaneous coronary intervention [PCI]) with surgery (coronary artery bypass grafting [CABG]), and addressed technical aspects of CABG. The general direction in 2022 confirms the superiority of CABG over PCI in patients with anatomically complex chronic CAD and supports an infarct-preventative effect as underlying mechanism. In addition, the relevance of proper surgical technique to achieve durable graft patency and the need for optimal medical treatment in CABG patients was impressively illustrated. In structural heart disease, the comparisons of interventional and surgical techniques have been characterized by prognostic and mechanistic investigations underscoring the need for durable treatment effects and reductions of valve-related complications. Early surgery for most valve pathologies appears to provide significant survival advantages, and two publications on the Ross operation prototypically illustrate an inverse association between long-term survival and valve-related complications. For surgical treatment of heart failure, the first xenotransplantation was certainly dominant, and in the aortic surgery field, innovations in arch surgery prevailed. This article summarizes publications perceived as important by us. It cannot be complete nor free of individual interpretation, but provides up-to-date information for decision-making and patient information.

Impact of a 36-hour Nonstop Training Course on Academic, Physical, and Mental Skills as well as Psychological Stress Perception in Cardiac Surgery Residents.

BACKGROUND: Making the right decision in stressful situations is required for goal-oriented action in cardiac surgery. Current labor laws prevent residents to be subjected to situations that test their stress tolerance. These situations often occur only later in the career. We simulated such conditions in a structured non-stop 36-hour cardiac surgical training course and assessed the participant's performance. METHODS: Fourteen advanced residents/junior staff surgeons were selected. The course was conducted in collaboration with the national antiterror police forces that provided coaching for teamplay, leadership, and responsibility awareness. The candidates attended graded and evaluated workshops/lectures and performed academic and surgical tasks. Psychological and surgical skill assessments were conducted at times 0, 12, 24, 36 hours. RESULTS: Progressive reductions in individual motivation, associated with increased stress and irritability levels, worsening mood, and fatigue were observed. Long- and short-term memory functions were unaffected and practical surgical performance even increased over time. CONCLUSION: Among the candidates, 36 hours of sleep deprivation did not lead to relevant changes in the skills required from a cardiac surgeon in daily life. Importantly, group dynamics substantially improved during the course, suggesting advances in the perception of responsibility and teamwork.

Cardiac Surgery 2021 Reviewed.

PubMed displayed more than 35,000 hits for the search term "cardiac surgery AND 2021." We used the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) approach and selected relevant publications for a results-oriented summary. As in recent years, we reviewed the fields of coronary and conventional valve surgery and their overlap with their interventional alternatives. COVID reduced cardiac surgical activity around the world. In the coronary field, the FAME 3 trial dominated publications by practically repeating SYNTAX, but with modern stents and fractional flow reserve (FFR)-guided percutaneous coronary interventions (PCIs). PCI was again unable to achieve non-inferiority compared with coronary artery bypass graft surgery (CABG) in patients with triple-vessel disease. Survival advantages of CABG over PCI could be linked to a reduction in myocardial infarctions and current terminology was criticized because the term "myocardial revascularization" is not precise and does not reflect the infarct-preventing collateralization effect of CABG. In structural heart disease, new guidelines were published, providing upgrades of interventional treatments of both aortic and mitral valve disease. While for aortic stenosis, transcatheter aortic valve implantation (TAVI) received a primary recommendation in older and high-risk patients; recommendations for transcatheter mitral edge-to-edge treatment were upgraded for patients considered inappropriate for surgery. For heart team discussions it is important to know that classic aortic valve replacement currently provides strong signals (from registry and randomized evidence) for a survival advantage over TAVI after 5 years. This article summarizes publications perceived as important by us. It can neither be complete nor free of individual interpretation, but provides up-to-date information for decision-making and patient information.

Right Mini-Thoracotomy for Aortic Plus Mitral with or without Tricuspid Valve Surgery.

OBJECTIVES: Minimally invasive surgery is increasingly performed for isolated aortic or mitral valve procedures. However, combined minimally invasive aortic and mitral valve surgery is rare. We report our initial experience performing multiple valve procedures through a right-sided mini-thoracotomy (RMT) compared with sternotomy. METHODS: A total of 264 patients underwent aortic and mitral with or without tricuspid valve surgery through RMT (n = 25) or sternotomy (n = 239). Propensity score matching was used for outcome comparisons. RESULTS: Of the 264 patients, 25 (age: 72 ± 10 years; 72% male) underwent double (n = 19) and triple valve surgery (n = 6) through RMT and 239 (age: 71 ± 11 years; 54% male) underwent double (n = 176) and triple valve surgery (n = 63) through sternotomy. Sternotomy patients had more co-morbidities and preoperative risk factors (EuroSCORE II 10.25 ± 10.89 vs. RMT 3.58. ± 4.98; p < 0.001). RMT procedures were uneventful without intraoperative complications or conversions to sternotomy. After propensity score matching, surgical procedures were comparable between groups with a higher valve repair rate in RMT. Despite longer cardiopulmonary bypass times in RMT, there was no evidence for differences in 30-day mortality (RMT: n = 2 vs. sternotomy: n = 2) and there were no significant differences in other outcomes. During 5-year follow-up, reoperation was required in sternotomy patients only (n = 2). Follow-up echocardiography showed durable results after valve surgery. RMT patients showed higher survival probability compared with sternotomy, although this difference was not significant (hazard ratio = 0.33; 95% confidence interval: 0.06-1.65; p = 0.18). CONCLUSION: Combined aortic plus mitral with or without tricuspid valve surgery can safely be performed through a RMT with a trend toward better mid-term outcomes.

Treatment of valvular heart disease in young patients-"early evidence" versus "latest fashion".

Is the performance of locally manufactured mechanical valve prostheses relevant for modern cardiac surgery, in which mechanical valve replacement has become a rarity? This question comes to mind reading the article in this issue of the Journal demonstrating equal outcomes of the TTK Chitra tilting disk mechanical heart valve prostheses in comparison to the SJM bi-leaflet blockbuster. The evidence documenting efficacy of mechanical valve replacement stems from the early ages of cardiac surgery, but often demonstrates superior outcomes in terms of survival and hemodynamics. Yet, the latest fashion in the Western world consists biological choices in combination with new transcatheter techniques (valve in valve options) or the Ozaki or Ross procedures. As long-term results are often missing and documented advantages for mechanical valves stems from early evidence, the local emphasis of mechanical valve replacement may possibly result in superior individual prognoses compared to following the Western world's latest fashions. Individual patient information and decision making moves into focus.

Neurocognitive decline in cardiac surgery-Distraction rather than destruction?

BACKGROUND: A neurocognitive decline is an undesirable event that can be observed in patients after cardiac surgery. It has been related to the use of cardiopulmonary bypass (CPB). Minor embolic or hyperinflammatory mechanisms are thought to be responsible. In this issue of the Journal of Cardiac Surgery, the neurocognitive decline was observed in 22 of 30 patients after cardiac surgery with CPB. Repeatable neuropsychological status tests were used and scores 4 days after surgery were 5%-15% lower than before. Mechanistic investigations with glycemic control and transcriptomic and cytokine analyses failed to provide an explanation but the frequency of this observation is worrisome. DISCUSSION: However, available evidence suggests that neurocognitive dysfunction disappears within a few months, and later on no difference to controls that did not undergo surgery can be detected. In addition, similar degrees of neurocognitive dysfunction can be observed after noncardiac surgery and even after percutaneous coronary intervention (PCI). A most recent comparison of memory decline after CABG and PCI also suggests no difference between the two invasive treatment options for coronary artery disease. All these findings argue against a primarily CPB-associated mechanism. Interestingly, test subjects from a consumer investigation showed a 10% decline in their working memory just by placing their cell phone on the table, suggesting that being distracted may also affect neurocognitive function. Given the reversibility of surgery- and intervention-associated neurocognitive dysfunction, we question destructive, embolic, or inflammatory-associated mechanisms. Distractive aspects of intervention-associated stress may also play a role. CONCLUSION: In any case, neurocognitive decline after cardiac surgery does not appear to be surgery-specific.

Cardiac Surgery 2020 Reviewed.

In 2020, nearly 30,000 published references appeared in the PubMed for the search term "cardiac surgery." While SARS-CoV-2 affected the number of surgical procedures, it did not affect outcomes reporting. Using the PRISMA approach, we selected relevant publications and prepared a results-oriented summary. We reviewed primarily the fields of coronary and conventional valve surgery and their overlap with interventional alternatives. The coronary field started with a discussion on trial data value and their interpretation. Registry comparisons of coronary artery bypass surgery (CABG) and percutaneous coronary intervention confirmed outcomes for severe coronary artery disease and advanced comorbidities with CABG. Multiple arterial grafting was best. In aortic valve surgery, meta-analyses of randomized trials report that transcatheter aortic valve implantation may provide a short-term advantage but long-term survival may be better with classic aortic valve replacement (AVR). Minimally invasive AVR and decellularized homografts emerged as hopeful techniques. In mitral and tricuspid valve surgery, excellent perioperative and long-term outcomes were presented for structural mitral regurgitation. For both, coronary and valve surgery, outcomes are strongly dependent on surgeon expertise. Kidney disease increases perioperative risk, but does not limit the surgical treatment effect. Finally, a cursory look is thrown on aortic, transplant, and assist-device surgery with a glimpse into the current stand of xenotransplantation. As in recent years, this article summarizes publications perceived as important by us. It does not expect to be complete and cannot be free of individual interpretation. We aimed to provide up-to-date information for decision-making and patient information.

Cardiac Surgery 2019 Reviewed.

For the year 2019, almost 25,000 published references can be found in PubMed when entering the search term "cardiac surgery." We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses approach for article selection and reviewed the main fields of adult cardiac surgery (i.e., coronary, valve, aortic, and heart failure surgery). The past decade has experienced an enormous development of interventional techniques that compete more and more with classic surgery. This contest was broadly visible in 2019. It peaked over the interpretation of the EXCEL trial data, where percutaneous coronary intervention and coronary artery bypass grafting (CABG) for left main disease were compared. A novel pathomechanism for CABG was proposed, potentially answering open questions in the field. In aortic valve surgery, two low-risk trials comparing transcatheter aortic valve implantation (TAVI) to classic aortic valve replacement (surgical aortic valve replacement) received attention for showing equal or superior short-term outcomes for TAVI. Longer follow-up information from recent trials became available presenting results emphasizing the need for joint decision making. While publications addressing surgery on the aorta and the mitral and tricuspid valves were less abundant, there was substantial activity regarding left ventricular assist device support and heart transplantation. This article attempts to summarize the most pertinent publications. It does not expect to be complete and cannot be free of individual interpretation. We aimed to provide a condensed summary of 2019s publications with a stimulus for in-depth reading and a basis supporting patient information.

Predictors of Outcome for Aortic Valve Reimplantation Including the Surgeon-A Single-Center Experience.

INTRODUCTION: Aortic valve reimplantation is considered technically demanding. We searched for predictors of long-term outcome including the surgeon as risk factor. METHODS: We selected all aortic valve reimplantations performed in our department between December 1999 and January 2017 and obtained a complete follow-up. The main indications were combined aortic aneurysm plus aortic valve regurgitation (AR), 69% and aortic dissections (15%). In 14%, valves were bicuspid. Cusp repair was performed in 27% of patients. One-third received additional procedures (coronary artery bypass grafting, mitral, or arch surgery). We performed multivariable analyses for independent risk factors of short- and long-term outcomes, including "surgeon" as variable. Twelve different surgeons operated on 193 patients. We created three groups: surgeons A and B with 84 and 64 procedures, respectively, and surgeon C (10 surgeons for 45 patients). RESULTS: Cardiopulmonary bypass and clamp times were 176 ± 45 and 130 ± 24 minutes, respectively. In-hospital mortality was 2%. Postoperatively, 5% had mild and 0.5% had moderate AR. Kaplan-Meier's survival estimates, freedom from reoperation, and freedom from severe AR at 12 years were 97 ± 1, 93 ± 2, and 91 ± 3%, respectively. Age and chronic obstructive pulmonary disease appeared as risk factors for perioperative complications by univariate analysis. Age, coronary artery disease, and duration of cardiopulmonary bypass, but not surgeon, presented as risk factors by multivariable analysis. CONCLUSION: The results suggest that if a David procedure is performed successfully, long-term durability may be excellent. They also suggest that good and durable results are possible even with limited experience of the operating surgeon.

Lost in circulation.

BACKGROUND: Device complications in complex percutaneous coronary interventions are rare but potentially deadly. Surgical removal is often required. However, an evaluation of surgical therapy beyond case reports is practically not existent. METHODS: We prospectively followed all cases of retained guide wires and/or other devices referred to us for surgical removal between 2015 and 2019 and retrospectively searched our database for such cases between 2010 and 2014. RESULTS: From 2015 on, eight cases were referred for surgical removal from six different cardiology departments. In the 5 years before, there was not a single case. Six patients were operated emergently. Patients were 60.5 ± 5.42 years old, overweight (body mass index 30.1 ± 3.77) and except for one case (left ventricular-assist device) showed preserved ejection fraction (EF) (mean EF 57 ± 18.01). The retained devices were mostly located in the right coronary artery (50%), followed by the circumflex artery (37.5%) and diagonal branch (12.5%). The devices were remnants of guide wires (n = 4), balloon catheters (n = 3), and in one case a rotablator. Full sternotomy was performed in six patients and two received a left-sided minithoracotomy (n = 2). The operations were performed on-pump in five (62.5%) and off-pump in three patients. Complete extraction of the foreign bodies was possible in all patients. Two patients died; one in unrelated multiorgan failure and one due to retained-device-related right heart failure. The other patients survived and had uneventful postoperative courses. CONCLUSIONS: Retained foreign bodies from cardiac interventions can be completely removed surgically using individualized approaches. There appears to be a trend toward a rising incidence of such interventional complications.

Minimally Invasive, Isolated Tricuspid Valve Redo Surgery: A Safety and Outcome Analysis.

BACKGROUND: Isolated tricuspid valve (TV) surgery is considered a high risk-procedure. The optimal surgical approach is controversial. We analyzed our experience with isolated TV redo surgery performed either minimally invasively (redo-MITS) or through sternotomy. METHODS: We retrospectively analyzed all patients with previous cardiac surgery who underwent redo-MITS (n = 26) and compared them to redo-Sternotomy (n = 17). A group of primary-MITS (n = 61) served as control. RESULTS: The redo-MITS approach consisted of a right anterolateral mini-thoracotomy, transpericardial right atrial access, and beating heart TV surgery without caval occlusion. Redo-MITS patients were oldest and had the most comorbidities (EuroScore II: 9.83 ± 6.05% versus redo-Sternotomy: 8.42 ± 7.33% versus primary-MITS: 4.15 ± 4.84%). There were no intraoperative complications or conversions to sternotomy in both MITS groups. Redo-Sternotomy had the highest 30-day mortality (24%), the poorest long-term survival, and the highest perioperative complication rate. Redo-MITS did not differ in perioperative outcome from primary-MITS. Multivariable logistic regression analysis identified redo-Sternotomy (odds ratio [OR] = 9.76; 95% confidence interval [CI] 1.88-63.26), liver cirrhosis (OR = 9.88; 95% CI 2.20-54.20), and body mass index (BMI) (OR = 1.16; 95% CI 1.02-1.35) as independent predictors of 30-day mortality. The Cox model revealed redo-Sternotomy (hazard ratio [HR] = 2.67; 95% CI 1.18-6.03), liver cirrhosis (HR = 3.31; 95% CI 1.45-7.58), and pulmonary hypertension (HR = 2.26; 95% CI 1.04-4.92) as risk factors for poor long-term survival. TV surgery significantly reduces NYHA class. CONCLUSION: Minimally invasive, isolated TV surgery as reoperation without caval occlusion and on the beating heart can be safe and may improve clinical outcome.

Invasive Treatment of Left Main Coronary Artery Disease: From Anatomical Features to Mechanistic Differences.

There is debate on the best treatment for significant stenoses of the left main (LM) coronary artery. The available evidence is based on four randomized trials, which were either performed specifically to assess patients with LM disease (EXCEL, NOBLE, PRECOMBAT) or had a significant fraction of patients with this disease pattern (SYNTAX). A meta-analysis revealed no difference in periprocedural and 5-year mortality but demonstrated a significant reduction of spontaneous myocardial infarction (MI) with CABG. Furthermore, the recently published SWEDEHEART registry data have shown survival advantage and fewer MACCE with CABG for LM disease after adjustment. In general, patients with more severe coronary artery disease (CAD) appear to have a survival advantage with CABG both over PCI and medical therapy (independent of the presence or absence of LM stenosis), which is always associated with a reduction of spontaneous MI in the CABG arm. Since the nomenclature of LM disease does not automatically reflect the complexity of CAD, we review the nature of LM disease in this article. We mechanistically assess the treatment effects of PCI and CABG for patients with LM disease, which is rarely isolated, often distal, and mostly associated with varying degrees of single and multi-vessel disease. We conclude that in patients with isolated LM shaft lesions and associated diseases of low complexity, the risk of spontaneous MI is lower, and PCI may achieve similar long-term outcomes compared to CABG. Thus, heart teams are essential for selecting the best treatment option and should focus on assessing infarction risk in chronic CAD.

Minimally Invasive Correction of Failed Percutaneous Atrial Septal Closure with Device Embolization.

We present the case of a minimally invasive surgical correction for failed percutaneous atrial septal defect (ASD) closure in a 57-year-old female patient with residual ASD, tricuspid regurgitation, atrial fibrillation, and embolization of one of two occluders to the superior mesenteric artery. Our surgical approach consisted of anterolateral minithoracotomy, aortic and femoral vein cannulation, cryoablation, cardiac device removal, closure of ASD with autologous pericardium, and tricuspid repair. The procedure was uneventful and patient was discharged home on postoperative day 4.

Antithrombotic Therapy in Patients With Infective Endocarditis: A Systematic Review and Meta-Analysis.

Background: Antithrombotic therapy (ATT) in patients with infective endocarditis (IE) is challenging. Objectives: The authors evaluated the impact of anticoagulant and antiplatelet therapy on clinical endpoints in IE patients. Methods: We performed a systematic review and meta-analysis comparing IE patients with prior and/or ongoing use of ATT vs those without any ATT during IE course. Primary outcome was reported in-hospital cerebrovascular events. Secondary outcomes were in-hospital mortality, intracranial hemorrhage (ICH), systemic thromboembolism (ST), and mortality within 6 months. Results: Twelve studies, with a total of 12,151 patients, were included. The primary endpoint was not different comparing 10,115 IE patients with or without prior anticoagulation (OR: 1.10; 95% CI: 0.56-2.17; P = 0.77) or comparing 838 IE patients with or without prior antiplatelet (OR: 0.90; 95% CI: 0.61-1.33; P = 0.61). In-hospital mortality was lower in IE patients with prior anticoagulation compared to those without (OR: 0.74; 95% CI: 0.57-0.96; P = 0.03). There was no difference in reported ICH rates between patients with or without prior anticoagulation (OR: 0.54; 95% CI: 0.27-1.09; P = 0.09) or between patients with or without prior antiplatelet (OR: 0.35; 95% CI: 0.11-1.10; P = 0.07). The rate of ST was lower in IE patients with prior antiplatelet therapy compared to those without (OR: 0.53; 95% CI: 0.38-0.72; P < 0.01). Conclusions: ATT in IE patients was not associated with higher frequency of cerebrovascular events or ICH. Moreover, we found that the use of anticoagulation was associated with decreased in-hospital mortality and the use of antiplatelets was associated with decreased ST. Due to the limitations of this study, these results should be interpreted cautiously showing the necessity of a randomized setup.
