Abstract
OBJECTIVE Minimally invasive approaches are being used increasingly in cardiac surgery and applied in a wider range of operations, including complex aortic procedures. The aim of this study was to examine the safety and feasibility of a partial upper sternotomy approach for isolated elective aortic root replacement (a modified Bentall procedure). METHODS We performed a retrospective analysis of 768 consecutive patients who had undergone isolated Bentall surgery between January 2000 and January 2021 at our institution, with the exclusion of re-operations, endocarditis, acute aortic dissections, and root replacement with major concomitant procedures such as multi-valve or coronary bypass surgery. A total of 98 patients were operated on via partial sternotomy (PS) and were matched 2:1 to 196 patients operated on via full sternotomy (FS). RESULTS The procedure time was 12 min longer in the PS group (205 min vs. 192.5 min in the FS group, p = 0.002), however, cardiopulmonary bypass and aortic cross-clamp times were comparable between groups. Eight PS-procedures were converted to full sternotomy, predominantly for bleeding complications (n = 6). Re-exploration for acute bleeding was necessary in 11% of the PS group and 4.1% of the FS group (p = 0.02). Five FS patients and none in the PS group required emergency coronary bypass grafting for postoperative coronary obstruction (p = 0.2). PS patients were hospitalized for a significantly shorter period (9.5 days vs. 10.5 days in the FS group, respectively). There were no significant differences regarding in-hospital (p = 0.4) and mid-term mortality (p = 0.73), as well as for other perioperative complications. CONCLUSIONS Performing Bentall operations via partial upper sternotomy is associated with similar perfusion and cross-clamp times, as well as overall mortality, when compared to a full sternotomy approach. A low threshold for conversion to full sternotomy should be accepted if limited access proves insufficient for the handling of intraoperative complications, particularly bleeding.

Abstract
Abstract
Background
Hybrid coronary revascularization (HCR) is a Heart Team directed strategy for selected patients with mutlivessel coronary artery disease. However, data on long-term results are lacking.
Purpose
To analyse long-term outcomes after HCR over a 20-year period.
Methods
Between 1996 and 2020, a total of 2667 consecutive patients underwent minimally invasive direct coronary artery bypass grafting (MIDCAB) at our institution, and 177 of these were planned HCR cases. Planned HCR consisted of a MIDCAB procedure to the left anterior descending (LAD) artery preceded or followed by percutaneous intervention (PCI) of non-LAD lesions. We excluded patients who underwent prior cardiac surgery and patients with emergency indications for revascularization (either surgical or transcatheter). Short- and long-term results for the entire cohort were analysed and a propensity score-matched comparison was performed between MIDCAB-first and PCI-first revascularization strategies.
Results
The mean age of all patients was 67 (±12) years with 37% suffering from diabetes (n=67). The median time-interval between MIDCAB and PCI was 22 days (IQR 5–53). Thirty-day mortality was 3.9% for the entire cohort. A total of 9 patients (5.0%) underwent early target vessel revascularization; 4 patients (2.2%) involving the LAD following the MIDCAB procedure and 5 patients (2.8%) involving non-LAD vessels following PCI. The rate of incomplete revascularization following completion of HCR was 25.4% (n=45). Long-term survival was 53.5% at 15 years and 30.4% at 20 years and the rate of repeat revascularization with PCI or surgery was 15.8% (n=28). The propensity matched sub-analysis of MIDCAB- versus PCI-first strategy showed no significant differences with regard to short- and long-term outcomes. Age (HR: 1.01, 95% CI 0.98–1.04, p=0.042) and incomplete revascularization (HR: 2.60, 95% CI 1.26–5.34; p=0.01) were independent risk factors for follow-up mortality.
Conclusions
Hybrid coronary revascularization as a less invasive strategy for selected patients is associated with acceptable 20-year survival. However, repeat revascularization rates are substantial.

Abstract
Background Coronary artery bypass can be performed off pump (OPCAB) without cardiopulmonary bypass. However, trends over time for OPCAB versus on-pump (ONCAB) use and long-term outcome has not been reported, nor has their long-term outcome been compared. Methods and Results We queried the national Veterans Affairs database (2005-2019) to identify isolated coronary artery bypass procedures. Procedures were classified as OPCAB on ONCAB using the as-treated basis. Trend analyses were performed to evaluate longitudinal changes in the preference for OPCAB. The median follow-up period was 6.6 (3.5-10) years. An inverse probability weighted Cox model was used to compare all-cause mortality between OPCAB and ONCAB. From 47 685 patients, 6759 (age 64±8 years) received OPCAB (14%). OPCAB usage declined from 16% (2005-2009) to 8% (2015-2019). Patients with triple vessel disease who received OPCAB received a lower mean number of grafts (2.8±0.8 versus 3.2±0.8; P<0.01). The ONCAB 5-, 10-, and 15-year survival rates were 82.9% (82.5-83.3), 60.4% (59.8-61.1), and 37.2% (36.1-38.4); correspondingly, OPCAB rates were 80.7% (79.7-81.7), 57.4% (56-58.7), and 34.1% (31.7-36.6) (P<0.01). OPCAB was associated with increased risk-adjusted all-cause mortality (hazard ratio, 1.15 [1.13-1.18]; P<0.01) and myocardial infarction (incident rate ratio, 1.16 [1.05-1.28]; P<0.01). Conclusions Over 15 years, OPCAB use declined considerably in Veterans Affairs medical centers. In Veterans Affairs hospitals, late all-cause mortality and myocardial infarction rates were higher in the OPCAB cohort.

Long-term survival after coronary bypass surgery with multiple versus single arterial grafts. Eur J Cardiothorac Surg 2021; 61:925-933. [PMID: 34618017 PMCID: PMC8947797 DOI: 10.1093/ejcts/ezab392] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/27/2021] [Revised: 07/21/2021] [Accepted: 08/01/2021] [Indexed: 01/07/2023] Open
Abstract
OBJECTIVES This study sought to evaluate the long-term differences in survival between multiple arterial grafts (MAG) and single arterial grafts (SAG) in patients who underwent coronary artery bypass grafting (CABG) in the SYNTAX study. METHODS The present analysis included the randomized and registry-treated CABG patients (n = 1509) from the SYNTAX Extended Survival study (SYNTAXES). Patients with only venous (n = 42) or synthetic grafts (n = 1) were excluded. The primary end point was all-cause death at the longest follow-up. Multivariable Cox regression was used to adjust for differences in baseline characteristics. Sensitivity analysis using propensity matching with inverse probability for treatment weights was performed. RESULTS Of the 1466 included patients, 465 (31.7%) received MAG and 1001 (68.3%) SAG. Patients receiving MAG were younger and at lower risk. At the longest follow-up of 12.6 years, all-cause death occurred in 23.6% of MAG and 40.0% of SAG patients [adjusted hazard ratio (HR) 0.74, 95% confidence interval (CI) (0.55-0.98); P = 0.038], which was confirmed by sensitivity analysis. MAG in patients with the three-vessel disease was associated with significant lower unadjusted and adjusted all-cause death at 12.6 years [adjusted HR 0.65, 95% CI (0.44-0.97); P = 0.033]. In contrast, no significance was observed after risk adjustment in patients with the left main disease, with and without diabetes, or among SYNTAX score tertiles. CONCLUSIONS In the present post hoc analysis of all-comers patients from the SYNTAX trial, MAG resulted in markedly lower all-cause death at 12.6-year follow-up compared to a SAG strategy. Hence, this striking long-term survival benefit of MAG over SAG encourages more extensive use of multiple arterial grafting in selected patients with reasonable life expectancy.

Abstract
BACKGROUND Coronary bypass artery grafting (CABG) has a higher procedural risk of stroke than percutaneous coronary intervention (PCI), but may offer better long-term survival. The optimal revascularization strategy for patients with prior cerebrovascular disease (CEVD) remains unclear. METHODS AND RESULTS The SYNTAXES study assessed the vital status out to 10 year of patients with three-vessel disease and/or left main coronary artery disease enrolled in the SYNTAX trial. The relative efficacy of PCI vs. CABG in terms of 10 year all-cause death was assessed according to prior CEVD. The primary endpoint was 10 year all-cause death. The status of prior CEVD was available in 1791 (99.5%) patients, of whom 253 patients had prior CEVD. Patients with prior CEVD were older and had more comorbidities (medically treated diabetes, insulin-dependent diabetes, metabolic syndrome, peripheral vascular disease, chronic obstructive pulmonary disease, impaired renal function, and congestive heart failure), compared with those without prior CEVD. Prior CEVD was an independent predictor of 10 year all-cause death (adjusted HR: 1.35; 95% CI: 1.04-1.73; p = 0.021). Patients with prior CEVD had a significantly higher risk of 10 year all-cause death (41.1 vs. 24.1%; HR: 1.92; 95% CI: 1.54-2.40; p < 0.001). The risk of 10 year all-cause death was similar between patients receiving PCI or CABG irrespective of the presence of prior CEVD (p-interaction = 0.624). CONCLUSION Prior CEVD was associated with a significantly increased risk of 10 year all-cause death which was similar in patients treated with PCI or CABG. These results do not support preferential referral for PCI rather than CABG in patients with prior CEVD. TRIAL REGISTRATION SYNTAX: ClinicalTrials.gov reference: NCT00114972.

Proximal aortic aneurysms: correlation of maximum aortic diameter and aortic wall thickness. Eur J Cardiothorac Surg 2021; 60:322-330. [PMID: 33822923 DOI: 10.1093/ejcts/ezab147] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2020] [Revised: 01/21/2021] [Accepted: 01/31/2021] [Indexed: 01/15/2023] Open
Abstract
OBJECTIVES The goal of therapy of proximal aortic aneurysms is to prevent an aortic catastrophe, e.g. acute dissection or rupture. The decision to intervene is currently based on maximum aortic diameter complemented by known risk factors like bicuspid aortic valve, positive family history or rapid growth rate. When applying Laplace's law, wall tension is determined by pressure × radius divided by aortic wall thickness. Because current imaging modalities lack precision, wall thickness is currently neglected. The purpose of our study was therefore to correlate maximum aortic diameter with aortic wall thickness and known indices for adverse aortic events. METHODS Aortic samples from 292 patients were collected during cardiac surgery, of whom 158 presented with a bicuspid aortic valve and 134, with a tricuspid aortic valve. Aortic specimens were obtained during the operation and stored in 4% formaldehyde. Histological staining and analysis were performed to determine the thickness of the aortic wall. RESULTS Patients were 62 ± 13 years old at the time of the operation; 77% were men. The mean aortic dimensions were 44 mm, 41 mm and 51 mm at the aortic root, sinotubular junction and ascending aorta, respectively. Aortic valve stenosis was the most frequent (49%) valvular dysfunction, followed by aortic valve regurgitation (33%) and combined dysfunction (10%). The maximum aortic diameter at the ascending level did not correlate with the thickness of the media (R = 0.07) or the intima (R = 0.28) at the convex sample site. There was also no correlation of the ascending aortic diameter with age (R = -0.18) or body surface area (R = 0.07). The thickness of the intima (r = 0.31) and the media (R = 0.035) did not correlate with the Svensson index of aortic risk. Similarly, there was a low (R = 0.29) or absent (R = -0.04) correlation between the aortic size index and the intima or media thickness, respectively. There was a similar relationship of median thickness of the intima in the 4 aortic height index risk categories (P < 0.001). CONCLUSIONS Aortic diameter and conventional indices of aortic risk do not correlate with aortic wall thickness. Other indices may be required in order to identify patients at high risk for aortic complications.

Supracommissural replacement of the ascending aorta and the aortic valve via partial versus full sternotomy-a propensity-matched comparison in a high-volume centre. Eur J Cardiothorac Surg 2021; 61:479-487. [PMID: 34453828 DOI: 10.1093/ejcts/ezab373] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/05/2021] [Revised: 06/26/2021] [Accepted: 07/18/2021] [Indexed: 12/11/2022] Open
Abstract
OBJECTIVES Full sternotomy (FS) is the common surgical access for patients undergoing open aortic valve replacement (AVR) with concomitant supracommissural replacement of the tubular ascending aorta. Since minimally invasive approaches are being used with increasing frequency in cardiac surgery, the aim of this study was to compare outcomes of patients undergoing AVR with supracommissural replacement of the tubular ascending aorta via FS versus partial upper sternotomy (PS). METHODS We included all patients who underwent elective AVR with concomitant supracommissural replacement of the tubular ascending aorta at our institution between 2000 and 2015. Exclusion criteria were emergency surgery, other major concomitant procedures and reoperations. After 2:1 propensity score matching, outcomes of patients with PS and FS were compared. RESULTS A total of 652 consecutive patients were included, 117 patients operated via PS and 234 patients operated via FS. Cardiopulmonary bypass time and aortic cross-clamp time of the PS and FS groups were 89 vs 92 min (P = 0.2) and 65 vs 70 min (P = 0.3), respectively. Postoperative morbidity was low and there were no significant differences in postoperative outcomes between patient groups. In-hospital mortality was 1.7% in the PS vs 0.4% in the FS group (P = 0.3). Kaplan-Meier analysis revealed no difference in mid-term survival (P = 0.3). Reoperation rates for valve or aortic complications were very low with no significant difference between groups. CONCLUSIONS In a high-volume centre with extensive experience in minimally invasive cardiac surgery, AVR with concomitant supracommissural replacement of the tubular ascending aorta via PS results in similar outcomes with regard to safety and longevity when compared to conventional FS.

Abstract
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.

Abstract
The true incidence of spinal cord injury associated with modern hybrid extended arch/descending aortic procedures utilizing a frozen elephant trunk (fET) remains unclear, and it is estimated with ~5-8%. Prolonged distal arrest without sufficient hypothermic protection as well as extended coverage of segmental arteries have been suggested to cause this complication, previously uncommon in open arch surgery. Recently, extensive clinical and experimental research led to the implementation of a new method of collateral network near-infrared spectroscopy (cnNIRS) to non-invasively monitor spinal cord oxygenation in the setting of extensive thoracoabdominal aortic repair. To date, limited experience with this method during arch procedures exists. Based on recent experiments regarding the optimal cnNIRS optode placement, we used this method for the first time during an fET procedure to document mid-thoracic paraspinous oxygenation levels.

Abstract
Spinal cord injury (SCI) is one major complication of open and endovascular thoracic and thoracoabdominal aortic aneurysm repair. Despite numerous neuroprotective adjuncts, the incidence of SCI remains high. This review article discusses established and novel adjuncts for spinal cord protection, including priming and preconditioning of the paraspinal collateral network, intraoperative systemic hypothermia, distal aortic perfusion, motor- and somatosensory evoked potentials and noninvasive cnNIRS monitoring as well as peri- and postoperative drainage of cerebrospinal fluid. Regardless of the positive influence of many of these strategies on neurologic outcome, to date no strategy assures definitive preservation of spinal cord integrity during and after aortic aneurysm repair.

Abstract
Background
In patients with complex coronary artery disease (CAD), women favored coronary artery bypass grafting surgery (CABG) compared to percutaneous coronary intervention (PCI) at 5 years in the SYNTAX trial, whereas mortality rates after PCI and CABG were not different in men. On the other hand, poor outcomes of women undergoing PCI were not observed in the PRECOMBAT and BEST trials.
The long-term optimal revascularization strategy according to gender has not been fully evaluated.
Purpose
In the SYNTAX Extended Survival (SYNTAXES) study, no significant difference existed in all-cause death between PCI and CABG at 10 years. This study aimed to assess treatment effect of PCI and CABG for 10-year all-cause death according to gender.
Methods
The SYNTAXES study evaluated vital status up to 10 years in 1,800 patients with de novo three-vessel disease (3VD) and/or left main coronary artery disease (LMCAD) randomized to treatment with CABG or PCI in the SYNTAX trial, and the pre-specified primary endpoint was all-cause death at 10 years. In this prespecified analysis, all-cause death at 10 years according to gender in patients undergoing PCI or CABG was evaluated.
Results
Of 1800 patients, 402 (22.3%) were women and 1398 (77.7%) were men. In women, the rate of mortality was significantly higher in the PCI arm at 5 years than in the CABG arm (19.3% vs. 10.3%; Log-rank p=0.010, Figure A), but the rates of mortality were not different at 10 years between the PCI and CABG arms (33.0% vs. 32.5%; Log-rank p=0.600, Figure A). In men, the mortality rate tended to be higher in the PCI arm at 10 years than in the CABG arm (27.0% vs. 22.5%; Log-rank p=0.082, Figure B), although the mortality rates were not different at 5 years between the PCI and CABG arms (12.4% vs. 12.3%; Log-rank p=0.957, Figure B).
Conclusion
The efficacy of CABG observed at 5 years disappeared at 10 years in women, whereas the efficacy of CABG became apparent after 5 years in men.

Abstract
Abstract
Background
The SYNTAX Extended Survival (SYNTAXES) study is an investigator-driven extension of follow-up of the SYNTAX trial, which 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. The SYNTAXES study is the first randomized trial that reported the complete 10-year data on all-cause death in patients with complex coronary artery disease.
Purpose
Patients with coronary artery disease (CAD) and concomitant diabetes mellitus (DM) or chronic kidney disease (CKD) are more susceptible to major adverse cardiovascular and cerebrovascular events. However, to date, the long-term prognosis and which revascularization strategy was associated with better clinical outcomes for patients with complex coronary artery disease and concomitant with DM and CKD have not been documented.
Methods
In this sub-analysis of the SYNTAXES trial, a total of 1,638 patients were classified into four subgroups according to the DM and CKD status: DM−/CKD− (n=999, 60.1%), DM+/CKD− (n=323, 19.7%), DM−/CKD+ (n=231, 14.1%), and DM+/CKD+ (n=85, 5.2%). The treatment effects of PCI and CABG were analyzed in each subgroup. The primary endpoint was all-cause death at 10 years.
Results
Compared with the DM−/CKD− patients, patients with DM+/CKD+ were older, more often had a history of stroke, hypertension, heart failure, and were more frequently presented with total occlusion, bifurcation lesion and three-vessel disease. At 10 years, patients with DM+/CKD+ had a 3.94-fold higher incidence of all-cause mortality compared with DM−/CKD− individuals (54.1% versus 18.9%, 95% CI [2.85–5.44]). Patients with DM−/CKD+ (38.1%, HR 2.36; 95% CI [1.83–5.44]) or DM+/CKD− (28.2%, HR 1.61; 95% CI [1.26–2.07]) had intermediate risk profile. For DM+/CKD+ patients, compared with PCI, those who underwent CABG were associated with lower incidence of all-cause mortality (64.3% versus 44.2%, adjusted HR 0.52; 95% CI [0.27–0.99], p=0.047, pinteraction=0.443). The number of needed-to-treat to reduce mortality for CABG was 12.
Conclusion
In the SYNTAX population, patients with DM and CKD are at markedly increased risk of long-term mortality rate compared with patients one or neither of these risk factors. For patients with both comorbidities, CABG was associated with better clinical outcome compared with PCI. These findings should be interpreted as hypothesis-generating.

Abstract
Abstract
Background
Periprocedural myocardial infarction (PMI) occurs frequently after both percutaneous coronary intervention (PCI) and bypass grafting surgery (CABG) in patients with complex coronary artery disease (CAD), and PMI has been shown to have a detrimental impact on mortality. On the other hand, long-term impact of PMI on mortality has not been fully evaluated.
Purpose
This study aimed to assess the impact of PMI according to SCAI definition on 10-year all-cause death in patients with complex CAD.
Methods
The SYNTAX Extended Survival (SYNTAXES) study evaluated vital status up to 10 years in 1800 patients with de novo three-vessel disease and/or left main coronary artery disease randomized to treatment with CABG or PCI in the SYNTAX trial. Blood was sampled for creatine kinase (CK) pre- and post-revascularisation, and the cardiac specific MB iso-enzyme (CK-MB) was determined only if the CK ratio ≥2 x the upper limit of normal (ULN). If the CK ratio <2 ULN, CK-MB assessment was not mandated. In this analysis, patients with at least one blood sampling within 48 hours of the procedure were included. PMI was defined as follows; peak CK-MB measured within 48 hours of the procedure ≥10 x ULN, or ≥5 x ULN with new Q-waves in 2 contiguous leads or new persistent left bundle branch block.
Results
Of 1800 patients, 1679 (93.2%) patients were included. Of 877 patients treated with PCI, PMI occurred in 26 patients (3.0%), whereas 14 (1.7%) PMIs were observed in 802 patients treated with CABG. Compared with patients without PMI, patients with PMI presented with unstable angina more frequently (45.0% vs. 28.7, p=0.033), and had a higher rate of bifurcation lesion (87.5% vs. 72.5, p=0.046). PMI was associated with a higher all-cause mortality at 10 years compared with no PMI (55.3% vs. 25.4%; Log-rank p<0.001, Figure), which was mainly driven by a high mortality rate within 1 year. In patients undergoing PCI, the mortality rates were significantly higher in patients with PMI not only within 1 year (Log-rank p<0.001) but also beyond one year (Log-rank p=0.016), compare to patients without PMI (Figure). On the other hand, in patients undergoing CABG, a higher mortality rate in patients with PMI was observed until 1 year (Log-rank p<0.001), but the impact of PMI on mortality beyond one year after CABG subsided (Log-rank p=0.308) (Figure 1).
Conclusion
PMI was associated with a poor prognosis at 10 years. The impact of PMI on mortality was strong within one year. Of note, the impact of PMI on mortality persisted beyond 1 year only in patients undergoing PCI. Patients who were treated with PCI and suffered PMI need careful follow-up beyond one year after revascularization.

Abstract
Abstract
Background
Coronary artery disease is the leading cause of death among elderly men and women worldwide. The aging society worldwide will lead to increasing numbers of elderly patients with multivessel coronary artery disease. Although age is recognized as one of the most important factors in a decision-making for revascularization of multivessel coronary artery disease, the very long-term outcomes in patients undergoing revascularization by percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) is still unclear.
Objectives
The aim of the present study was to investigate the association between revascularization strategies and 10-year outcomes in elderly patients.
Methods
The SYNTAX Extended Survival (SYNTAXES) study (NCT 03417050) 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, enrolling 1,800 patients with de novo three-vessel disease (3VD) and/or left main coronary artery disease (LMCAD) randomized to revascularization strategy with CABG versus PCI in the SYNTAX trial. Patients were divided into two groups according to the prespecified threshold of 70 years old; elderly patients (>70 years) and non-elderly patients (≤70 years). The primary endpoint of this study was all-cause death at 10 years.
Results
Out of 1,800 patients, 575 patients (31.9%) were classified as elderly (>70 years). The mean age ± standard deviation (SD) of the elderly patients and the non-elderly patients was 75.8±3.6 years and 60.1±7.4 years, respectively. Of note, elderly patients were more frequently female than non-elderly patients (33.6% vs. 17.1%, p<0.001). As expected, the elderly patients had higher prevalence of chronic kidney disease (43.4% vs. 7.9%, p<0.001), had higher anatomical SYNTAX score (30.2±11.8 vs 28.0±11.2 p<0.001) when compared to those of the non-elderly patients.
Up to 10 years, all-cause death occurred in 42.7% and 18.9% in the elderly and non-elderly patients, respectively (Log-rank p<0.001). The cubic spline curve showed an exponentially increase in all-cause death at 10 years according to the increase of age both in the PCI arm and the CABG arm. At 10 years, there was no significant difference in the risk of all-cause death between CABG vs. PCI either in elderly patients (41.5% vs. 44.0%; Log-rank p=0.53) or non-elderly patients (16.6% vs. 21.1%; Log-rank p=0.051).
Conclusion
CABG and PCI were equipoise in terms of risk of all-cause death at 10 years in patients with de novo 3VD and/or LMCAD irrespective of their age when stratified according to the prespecified threshold of 70 years old.

Loop neochord versus leaflet resection techniques for minimally invasive mitral valve repair: long-term results. Eur J Cardiothorac Surg 2020; 59:180-186. [DOI: 10.1093/ejcts/ezaa255] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2020] [Revised: 06/12/2020] [Accepted: 06/16/2020] [Indexed: 11/14/2022] Open
Abstract
Abstract
OBJECTIVES
Non-leaflet resection techniques including loop chordal replacement are being used with increasing frequency, but the long-term results of these techniques are still unknown. The aim of this study was to compare the long-term results of loop neochord replacement with leaflet resection techniques in patients undergoing minimally invasive mitral valve (MV) repair for MV prolapse.
METHODS
Between 1999 and 2014, 2134 consecutive MV prolapse patients underwent minimally invasive MV repair with isolated loop (n = 1751; 82.1%) or resection techniques (n = 383, 17.9%) at our institution. Follow-up data were available for 86% of patients with a mean follow-up time of 6.1 ± 4.3 years.
RESULTS
The 30-day mortality was 0.8% for all patients (loop: 0.7%, resection: 1.6%; P = 0.09). Leaflet resection was associated with more moderate or more mitral regurgitation on predischarge echocardiography (P = 0.003). The 1-, 5- and 10-year survival rates were 98 ± 1%, 95 ± 1% and 86 ± 2% for the loop technique versus 97 ± 1%, 92 ± 1% and 81 ± 2% for resection patients, respectively (P = 0.003). Significant predictors for late mortality were MV repair technique (P = 0.004), left ventricular ejection fraction (P < 0.001), age (P < 0.001) and myocardial infarction (P < 0.001). Freedom from MV reoperation at 1, 5 and 10 years was 98 ± 1%, 97 ± 1%, 97 ± 1% and 97 ± 1%, 97 ± 1%, 96 ± 1% for patients operated on with the loop technique and leaflet resection (P = 0.4).
CONCLUSIONS
In our patient cohort, MV repair with loop chordal replacement is associated with less early recurrent mitral regurgitation and very good long-term results when compared to classical leaflet resection techniques for MV prolapse and is therefore an excellent option for such patients.

Bicuspid aortic valve patients show specific epigenetic tissue signature increasing extracellular matrix destruction. Interact Cardiovasc Thorac Surg 2020; 29:937-943. [PMID: 31501876 DOI: 10.1093/icvts/ivz210] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2019] [Revised: 07/29/2019] [Accepted: 08/04/2019] [Indexed: 01/18/2023] Open
Abstract
OBJECTIVES Patients with a bicuspid aortic valve (BAV) have an increased risk for developing thoracic aortic aneurysm, which is characterized by the destruction of the elastic media of the aortic wall. Several important enzymes have been characterized to play key roles in extracellular matrix homeostasis, namely matrix metalloproteinases (MMPs). In this study, we investigated MMP-2 levels and their epigenetic regulation via the miR-29 family. METHODS Aortic tissue samples from 58 patients were collected during cardiac surgery, of which 30 presented with a BAV and 28 with a tricuspid aortic valve. Polymerase chain reaction, western blot analysis and immunohistochemistry were performed to analyse MMP-2. In addition, enzyme-linked immunosorbent assay measurements were carried out to investigate both MMP-2 and tissue inhibitor of metalloproteinase-2 levels. To examine the epigenetic regulation of aortic extracellular matrix homeostasis, we furthermore studied the expression levels of miR-29 via qRT-PCR. RESULTS Patients with a BAV were significantly younger at the time of surgery, presented significantly less frequently with arterial hypertension and displayed more often with an additional valvular disease. On a molecular level, we found that MMP-2 is increased on gene and protein level in BAV patients. Tissue inhibitor of metalloproteinase-2 levels do not differ between the groups. Interestingly, we also found that only miR-29A is significantly downregulated in BAVs. CONCLUSIONS Our findings highlight the importance of MMP-2 in the context of extracellular matrix destruction in BAV patients. We present new evidence that miR-29A is a crucial epigenetic regulator of these pathomechanistic processes and might hold promise for future translational research.

Prevalence of permanent pacemaker implantation after conventional aortic valve replacement—a propensity-matched analysis in patients with a bicuspid or tricuspid aortic valve: a benchmark for transcatheter aortic valve replacement. Eur J Cardiothorac Surg 2020; 58:130-137. [DOI: 10.1093/ejcts/ezaa053] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2019] [Revised: 01/24/2020] [Accepted: 01/29/2020] [Indexed: 12/13/2022] Open
Abstract
Abstract
OBJECTIVES
Elective treatment of aortic valve disease by transcatheter aortic valve replacement (TAVR) is becoming increasingly popular, even in patients with low risk and intermediate risk. Even patients with a bicuspid aortic valve (BAV) are increasingly considered eligible for TAVR. Permanent pacemaker implantation (PMI) is a known—frequently understated—complication of TAVR affecting 9–15% of TAVR patients with a potentially significant impact on longevity and quality of life. BAV patients are affected by the highest PMI rates, although they are frequently younger compared to their tricuspid peers. The aim of the study is to report benchmark data—from a high-volume centre (with a competitive TAVR programme) on PMI after isolated surgical aortic valve replacement (SAVR) in patients with BAV and tricuspid aortic valve (TAV).
METHODS
We performed a retrospective single-centre analysis on 4154 patients receiving isolated SAVRs (w/o concomitant procedures), between 2000 and 2019, of whom 1108 had BAV (27%). PMI rate and early- and long-term outcomes were analysed. For better comparability of these demographically unequal cohorts, 1:1 nearest neighbour matching was performed.
RESULTS
At the time of SAVR, BAV patients were on average 10 years younger than their TAV peers (59.7 ± 12 vs 69.3 ± 9; P < 0.001) and had less comorbidities; all relevant characteristics were equally balanced after statistical matching. Overall PMI rate was significantly higher in BAV patients (5.4% vs 3.8%; P = 0.03). BAV required PMI exclusively (100%) and TAV required predominately (96%) for persistent postoperative high-degree atrioventricular block. After matching, the PMI rate was similar (5.1% vs 4.4%, P = 0.5). In-hospital mortality in the matched cohort was 1% in both groups. Long-term survival was more favourable in BAV patients (94% vs 90% in TAV at 5 years; 89% vs 82% in TAV at 9 years; P = 0.013).
CONCLUSIONS
With SAVR, the overall incidence of PMI among BAV patients seems significantly higher; however, after propensity matching, no difference in PMI rates between BAV and TAV is evident. The PMI rate was remarkably lower among BAV patients after SAVR compared to the reported incidence after TAVR.

Abstract
OBJECTIVES Mitral valve (MV) annuloplasty ring dehiscence with subsequent recurrent mitral regurgitation represents an unusual but challenging clinical problem. Incidence, localization and outcomes for this complication have not been well defined. METHODS From 1996 to 2016, a total of 3478 patients underwent isolated MV repair with ring annuloplasty at the Leipzig Heart Centre. Of these patients, 57 (1.6%) underwent reoperation due to annuloplasty ring dehiscence. Echocardiographic data, operative and early postoperative characteristics as well as short- and long-term survival rates after MV reoperation were analysed. RESULTS Occurrences of ring dehiscence were acute (<30 days), early (≤1 year) and late (>1 year) in 44%, 33% and 23% of patients, respectively. Localization of annuloplasty ring dehiscence was found most frequently in the P3 segment (68%), followed by the P2 (51%) and the P1 segments (47%). The 30-day mortality rate and 1- and 5-year survival rates after MV reoperation were 2%, 89% and 74%, respectively. During reoperation, MV replacement was performed in 38 (67%) and MV re-repair in 19 (33%) patients. CONCLUSIONS Annuloplasty ring dehiscence is clinically less common, localized more frequently on the posterior annulus and occurs mostly acutely or early after MV repair. MV reoperation can be performed safely in such patients.

Abstract
BACKGROUND Concomitant use of tricuspid valve (TV) surgery and minimally invasive mitral valve (MV) repair is debatable due to a prolonged time of surgery with presumably elevated operative risk. Herein, we examined cardiopulmonary bypass times and 30-day mortality in patients who underwent MV repair with and without concomitant TV surgery. METHODS We retrospectively evaluated 3,962 patients with MV regurgitation who underwent minimally invasive MV repair without (n = 3,463; MVr group) and with (n = 499; MVr + TVr group) concomitant TV surgery between 1999 and 2014. Preoperative parameters between the groups were significantly different; therefore, propensity score matching was performed. RESULTS Mean cardiopulmonary bypass time for all patients was 125.5 ± 55.8 minutes in MVr and 162.0 ± 58.0 minutes in MVr + TVr (p < 0.001). Overall 30-day mortality was significantly different between these groups (4.8 vs. 2.1%; p < 0.001); however, after adjustment, there was no significant difference (3.3 vs. 1.2%; p = 0.07). Backward logistic regression revealed that cardiopulmonary bypass time was not a significant predictor for early mortality within the MVr + TVr cohort. CONCLUSION Concomitant TV repair using prosthetic rings through a minimally invasive approach is safe and does not lead to elevated early mortality in our patient cohort. Therefore, prolonged cardiopulmonary bypass time should not be the sole reason to rule out MV repair with concomitant TV repair and to prefer the use of suture techniques, which saves only a few minutes compared with prosthetic ring implantation.

Abstract
Background Infective valve endocarditis (IE) is associated with significant mortality and complication rates. The diagnosis impacts not only the prognosis but also the management of the disease. The aim of this article is to show the findings obtained from the implementation of our most important diagnostic tools and discuss our standard diagnostic process for patients with IE who underwent surgical treatment between 1994 and 2017. Methods Between December 1994 and January 2017 a total of 2,458 patients with IE underwent surgery at our institution. We analyzed clinical, microbiological, echocardiographic, and multi slice computer tomographic (MSCT) features in this group. Results The most often isolated involved valve was the aortic valve (59%). Prosthetic valve endocarditis (PVE) was present in almost one third of all cases. The most common valve failures were mitral valve insufficiency (MI) and aortic valve insufficiency (AI) (65% and 57% respectively). Almost one half of the aortic insufficiencies were severe. 63% of all vegetations assessed by echocardiography were larger than 1 cm. We detected a septic embolism in 44% of patients and the most common target organ was the spleen (25%). The most common isolated pathogen was Staphylococcus aureus (26%) and affected patients had a significant correlation with in-hospital mortality (P=0.004). Conclusions Echocardiography offers valuable information and is the most important diagnostic method in patients with IE. Preoperative MSCT contributes to the entire perioperative decision-making process. Microbiological diagnosis is mandatory in choosing and adjusting antibiotic therapy and also has prognostic value.

Percutaneous coronary intervention versus coronary artery bypass grafting in patients with three-vessel or left main coronary artery disease: 10-year follow-up of the multicentre randomised controlled SYNTAX trial. Lancet 2019; 394:1325-1334. [PMID: 31488373 DOI: 10.1016/s0140-6736(19)31997-x] [Citation(s) in RCA: 342] [Impact Index Per Article: 68.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/28/2019] [Revised: 08/09/2019] [Accepted: 08/12/2019] [Indexed: 12/15/2022]
Abstract
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.

Abstract
AbstractTricuspid valve (TV) regurgitation in patients after previous mitral valve surgery is usually a secondary failure and conditioned by a long-lasting left-sided valve failure. TV surgery in these patients represents a high-risk procedure regarding the operative strategy and perioperative management. This article will discuss the indication for TV surgery in patients with secondary TV regurgitation and previous mitral valve surgery, the choice of surgical access, as well as TV repair techniques and their postoperative results.

Abstract
Background Triple valve surgery (TVS) is associated with an elevated risk for operative mortality and thus remains a surgical challenge. We report our experience and results of TVS procedures, especially with respect to identification of preoperative risk factors, to improve patient selection. Methods Between December 1994 and January 2013, 487 consecutive patients (240 male, 247 female) underwent TVS at the Heart Center Leipzig, University of Leipzig. The data were prospectively collected and retrospectively analyzed. Univariate and multivariable regression analyses were performed to identify risk factors. Results The 30-day mortality was 16.1% and the long-term survival at 1 year and 5 years was 71.8% and 54.6%, respectively. Multivariable logistic regression analysis identified previous myocardial infarction to be the only significant predictor for early mortality. Age, New York Heart Association functional class IV, previous myocardial infarction, dialysis, and liver dysfunction were identified as preoperative predictors for late mortality. Furthermore, an increase of operative risk, given for each year, was observed during the study period. In contrast, 30-day mortality decreased during the observation time. Conclusion TVS is associated with a high surgical risk. Long-term survival is decreased, but acceptable for these high-risk patients. The series demonstrates that increasing surgical risk, age, and comorbidities are the future challenges in TVS.

Abstract
Background The aim of this study was to evaluate the perioperative characteristics and the short- and mid-term outcomes in patients undergoing tricuspid valve (TV) surgery for isolated TV endocarditis. Patients and Methods A total of 56 patients with isolated TV endocarditis underwent TV surgery at a single center between June 1995 and February 2012. Mean age of patients was 53.8 ± 17.1 years, 39 (69.6%) being male. The mean left ventricular ejection fraction was 60.4 ± 13.6% and 13 (23.2%) patients had diabetes mellitus. Average logistic EuroSCORE was 19.4 ± 17.0%. Mean follow-up was 4.7 ± 3.8 years. Results Microbiological investigations revealed positive blood cultures in 89.1% of patients and positive intraoperative swabs in 51.9%. The most common pathogen (42.9%) isolated was Staphylococcus aureus, followed by coagulase-negative staphylococcus (17.9%). Discussion A history of intravenous drug abuse (IVDA) was recorded in 11 patients (19.6%), of which 8 patients additionally had hepatitis C. A total of 15 patients (26.8%) had a permanent pacemaker/implantable cardioverter-defibrillator in situ. TV replacement was performed in 22 patients (39.3%) and TV repair was performed in 34 patients (60.7%). Overall 30-day mortality was 12.5%. Five-year survival was 63.9 ± 7.2% (95% confidence interval [CI]: 64.0-137.5 months). Freedom from reoperation for recurrent TV endocarditis was 91.7 ± 4.0% (95% CI: 152.3-179.3 months) at 5 years. Conclusion Blood culture is the most important tool to detect the causative pathogen causing IE of TV. The high risk of hepatitis C in patients with IVDA and IE of the TV should be mentioned.

Risk factors for mortality after pericardiectomy for chronic constrictive pericarditis in a large single-centre cohort. Eur J Cardiothorac Surg 2015; 48:e110-6.

Abstract
OBJECTIVES Constrictive pericarditis (CP) is an uncommon disease with multiple causes and unclear clinical outcomes. To date, few publications have clearly defined risk factors of poor outcomes after surgery for CP. We performed a retrospective analysis of almost 100 patients undergoing surgical treatment for CP at a single institution in order to identify risk factors for perioperative and long-term mortality. METHODS A total of 97 consecutive patients (67.0% male) undergoing surgery for CP at our institution from 1995 to 2012 were included in the study. CP was diagnosed either preoperatively by cardiac catheterization and appropriate imaging or during surgery. Preoperative and intraoperative risk factors for 30-day and late mortality were analysed using stepwise multivariate logistic and Cox regression analyses. Median follow-up was 1.23 ± 3.96 years (mean 3.08 ± 3.96 years). RESULTS The mean patient age was 60.0 ± 12.5 years and the underlying aetiology was idiopathic (50.5%), prior cardiac surgery (15.5%), prior mediastinal radiation (9.3%), and miscellaneous (24.7%). All patients underwent either radical (55.2%) or partial (44.8%) pericardiectomy. Concomitant procedures were performed in 54 (55.7%) patients. The total procedure time was 197.0 ± 105.0 min. Cardiopulmonary bypass (CPB) was used in 62 patients with a corresponding CPB time of 124.8 ± 68.4 min. In those patients who underwent CPB, cardioplegic arrest was performed in 53.2% of patients with a mean cross-clamp time of 74.9 ± 41.9 min. Overall 30-day, 1-year and 5-year survival rates were 81.4, 66.5 and 51.6%, respectively, without significant differences according to the underlying aetiology. Multivariate analysis revealed patients with reduced left ventricular ejection fraction (LVEF) [P = 0.01, odds ratio (OR) 3.6] and preoperative right ventricular dilatation (P = 0.04, OR 3.5) to be at significant risk of early mortality. Long-term mortality was independently predicted by the presence of coronary artery disease (CAD) [P < 0.001, hazard ratio (HR) 6.44], chronic obstructive pulmonary disease (P = 0.001, HR 4.21) and preoperative renal insufficiency (P = 0.012, HR 1.8). Concomitant tricuspid valve repair (TVR) appeared to provide protective effect on the long-term survival (P = 0.07). CONCLUSIONS Surgery for CP is associated with a significant risk based on the poor preoperative patient status. Whenever justified, partial over radical pericardiectomy should be preferred and TVR should be indicated liberally. Reduced LVEF and right ventricular dilatation were independent predictors for early mortality, whereas CAD, chronic obstructive pulmonary disease and renal insufficiency were risk factors for late mortality. Thus, an optimal timing for surgery on CP remains crucial to avoid secondary morbidity with an even worse natural prognosis.
