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. [ABSTRACT FROM AUTHOR]

Objectives: Benefits of tricuspid valve repair (TVR) in left ventricular assist device (LVAD) patients have been questioned. High TVR failure rates have been reported. Remaining or recurring TR was found to be a risk factor for right heart failure (RHF). Therefore, we assessed our experience. Methods: Since 12/2010, 195 patients have undergone LVAD implantation in our center. Almost half (n = 94, 48%) received concomitant TVR (LVAD+TVR). These patients were included in our analysis. Echocardiographic and clinical data were assessed. Median follow-up was 2.8 years (7 days–0.6 years). Results were correlated with clinical outcomes. Results: LVAD+TVR patients were 59.8 ± 11.4 years old (89.4% male) and 37.3% were INTERMACS level 1 and 2. Preoperative TR was moderate in 28 and severe in 66 patients. RV function was severely impaired in 61 patients reflected by TAPSE-values of 11.2 ± 2.9 mm (vs. 15.7 ± 3.8 mm in n = 33; p < 0.001). Risk for RHF according to EUROMACS-RHF risk score was high (>4 points) in 60 patients, intermediate (>2–4 points) in 19 and low (0–2 points) in 15. RHF occurred in four patients (4.3%). Mean duration of echocardiographic follow-up was 2.8 ± 2.3 years. None of the patients presented with severe and only five (5.3%) with moderate TR. The vast majority (n = 63) had mild TR, and 26 patients had no/trace TR. Survival at 1, 3 and 5 years was 77.4%, 68.1% and 55.6%, 30-day mortality was 11.7% (n = 11). Heart transplantation was performed in 12 patients (12.8%). Conclusions: Contrary to expectations, concomitant TVR during LVAD implantation may result in excellent repair durability, which appears to be associated with low risk for RHF.

Background: De novo cancers are feared complications after heart or lung transplantation. Recent data suggest that diabetes mellitus (DM) might also be a risk factor for cancer. We hypothesized that transplanted diabetic patients are at greater risk of developing cancer compared to non-diabetic ones. Methods: We reviewed 353 patients post-heart and/or -lung transplantation from our center between October 1999 and June 2021. Patients with follow-up <180 days (n = 87) were excluded from the analysis. The remaining 266 patients were divided into patients who had preoperative DM (n = 88) or developed it during follow-up (n = 40) and patients without DM (n = 138). Results: The diabetic cohort showed higher rates of malignancies in all patients (30.33 vs. 15.97%, p = 0.005) and in the matched population (31.9 vs. 16.1%, p < 0.001). There were also significantly more solid tumors (17.9 vs. 9.4%, p = 0.042; matched: 16.6 vs. 9.1%, p = 0.09) The presence of diabetes was associated with a 13% increased risk of cancer when compared to non-diabetic patients. New-onset post-transplant diabetes doubled the likelihood of cancer development. Conclusions: Pre-transplant diabetes mellitus increases the risk of cancer after heart and/or lung transplantation. However, new-onset diabetes after transplantation is associated with a much greater cancer risk. This information is relevant for screening during follow-up. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

For the year 2018, more than 22,000 published references can be found in PubMed when entering the search term "cardiac surgery". As in the last 4 years, this review focusses on conventional cardiac surgery publications which provide important and interesting information especially relevant for non-surgical colleagues. Interventional techniques have been considered if they were published in the context of classic surgical techniques. We have again reviewed the fields of coronary revascularization and valve surgery and briefly touched on aortic surgery and surgery for terminal heart failure. For revascularization of complex coronary artery disease, bypass grafting was reconfirmed as gold standard and computer-tomographic angiography established equipoise for decision-making with classic angiography. For aortic valve treatment, some new longer-term outcomes from TAVI vs. SAVR trials confirmed equipoise of both treatments for high and medium risk. New information was provided for INR-management of mechanical aortic valves as well as long-term experiences for alternatives to mechanical valves (i.e., Ross and the relatively new Ozaki procedure). In the mitral and tricuspid field, prevalence data illustrate a significant amount of under-treatment for mitral and tricuspid valve regurgitation and evidence for life prolonging-effects of surgery. Finally, elongation of the ascending aorta was identified as new risk factor for aortic dissection and 2 years outcome of the newest generation of left ventricular assist devices demonstrate impressive improvements in outcome. While this article attempts to summarize the most pertinent publications, it does not expect to be complete and cannot be free of individual interpretation. As in recent years, it provides a condensed summary that is intended to give the reader "solid ground" for up-to-date decision-making in cardiac surgery and a stimulus for in-depth reading.

For the year 2017, more than 21,000 published references can be found in PubMed when entering the search term “cardiac surgery”. This review focusses on conventional cardiac surgery, considering the new interventional techniques only if they were directly compared to classic techniques but also entails aspects of perioperative intensive care management. The publications last year provided a plethora of new and interesting information that helped to quantify classic surgical treatment effects and provided new guidelines for the management of structural heart disease, which made comparisons to interventional techniques easier. The field of coronary bypass surgery was primarily filled with confirmatory evidence for the beneficial role of coronary artery bypass grafting for complex coronary disease and equal outcomes for percutaneous coronary intervention for less complex disease including main stem lesions. For aortic valve treatment, the new guidelines provide an equal recommendation for surgical and transcatheter aortic valve replacement for high and intermediate risk giving specific check lists to individualize decision-making by the heart team. For low-risk aortic stenosis, surgical valve replacement remains the primary indication. For the mitral valve, the importance of surgical experience of the individual surgeon on short- and long-term outcome was presented and the prognostic impact of mitral repair for primary mitral regurgitation was emphasized. In addition, there were many relevant and interesting other contributions from the purely operative arena in the fields of tricuspid disease as well as terminal heart failure (i.e., transplantation and ventricular assist devices). While this article attempts to summarize the most pertinent publications, it does not have the expectation of being complete and cannot be free of individual interpretation. As in recent years, it provides a condensed summary that is intended to give the reader “solid ground” for up-to-date decision-making in cardiac surgery. [ABSTRACT FROM AUTHOR]

For the year 2016, more than 20,000 published references can be found in Pubmed when entering the search term 'cardiac surgery'. Publications last year have helped to more clearly delineate the fields where classic surgery and modern interventional techniques overlap. The field of coronary bypass surgery (partially compared to percutaneous coronary intervention) was enriched by five large prospective randomized trials. The value of CABG for complex coronary disease was reconfirmed and for less complex main stem lesions, PCI was found potentially equal. For aortic valve treatment, more evidence was presented for the superiority of transcatheter aortic valve implantation for patients with intermediate risk. However, the 2016 evidence argued against the liberal expansion to the low-risk field, where conventional aortic valve replacement still appears superior. For the mitral valve, many publications emphasized the significant impact of mitral valve reconstruction on survival in structural mitral regurgitation. In addition, there were many relevant and other interesting contributions from the purely operative arena in the fields of coronary revascularization, surgical treatment of valve disease, terminal heart failure (i.e., transplantation and ventricular assist devices), and aortic surgery. While this article attempts to summarize the most pertinent publications it does not have the expectation of being complete and cannot be free of individual interpretation. As in recent years, it provides a condensed summary that is intended to give the reader 'solid ground' for up-to-date decision-making in cardiac surgery. [ABSTRACT FROM AUTHOR]

For the year 2015, almost 19,000 published references can be found in PubMed when entering the search term 'cardiac surgery'. The last year has been again characterized by lively discussions in the fields where classic cardiac surgery and modern interventional techniques overlap. Lacking evidence in the field of coronary revascularization with either percutaneous coronary intervention or bypass surgery has been added. As in the years before, CABG remains the gold standard for the revascularization of complex stable triple-vessel disease. Plenty of new information has been presented comparing the conventional to transcatheter aortic valve implantation (TAVI) demonstrating similar short- and mid-term outcomes at high and low risk, but even a survival advantage with transfemoral TAVI at intermediate risk. In addition, there were many relevant and interesting other contributions from the purely operative arena. This review article will summarize the most pertinent publications in the fields of coronary revascularization, surgical treatment of valve disease, heart failure (i.e., transplantation and ventricular assist devices), and aortic surgery. While the article does not have the expectation of being complete and cannot be free of individual interpretation, it provides a condensed summary that is intended to give the reader 'solid ground' for up-to-date decision-making in cardiac surgery.
