RESUMEN
OBJECTIVE: Reoperative aortic root replacement (ARR) is a technically challenging procedure. This study assesses the influence of reoperation on outcomes following ARR, particularly after prior acute type A aortic dissection (ATAAD) repair. METHODS: Of the 1823 patients in this study, 1592 (87.3%) underwent primary ARR, and 231 (12.7%) underwent reoperative ARR. Within the reoperative ARR group, 69 patients (29.9%) had previous ATAAD repair, and 162 patients (70.1%) underwent reoperative ARR for other indications. RESULTS: Reoperative ARR patients exhibited higher rates of ischemic heart disease (13.9% vs. 3%, p<0.001), diabetes (10% vs. 5.3%, p=0.009), chronic pulmonary disease (9.1% vs. 5%, p=0.018), renal impairment (17.7% vs. 5.3%, p<0.001), and had lower ejection fraction (45.5 ± 8.1 vs. 47.6 ± 7.9, p<0.001) compared to primary ARR. The overall operative mortality was 0.4%, with no significant difference between groups (0.9% vs. 0.3%, p=0.485). At multivariable analysis previous operation was the most powerful predictor for major adverse events [OR 3.20 (2.12-4.79), p<0.001]. Reoperative ARR had a lower 10-year survival compared to primary ARR (67.4% vs. 85.9%, log-rank p<0.001). Multivariable analysis further confirmed that reoperation was significantly associated with 10-year mortality [HR 1.76 (1.01-3.06), p=0.044]. Among the reoperative ARR group, operative mortality after previous ATAAD repair was similar to that for other etiologies (0% v 1.2%, p=0.880). CONCLUSION: Patients undergoing reoperative ARR have more comorbidities and extensive aortic disease compared to those undergoing primary surgery. They face a 3.5-fold increased risk of major adverse events but no difference in operative mortality compared to primary ARR.
RESUMEN
OBJECTIVE: We sought to evaluate outcomes of valve-sparing root replacement (VSRR) in patients with bicuspid aortopathy (BAV) versus other connective tissue disorder (CTD). METHODS: This was a single-center cohort study of consecutive patients undergoing VSRR via reimplantation from 2000 to 2023 with BAV or CTD. Operative outcomes, Kaplan-Meier survival estimates, and cumulative risk of reoperation and recurrent aortic insufficiency (AI) with the competing risk of death were assessed. RESULTS: Of 516 patients who underwent VSRR, 109 (51.9%) had BAV and 101 (48.1%) had CTD. Patients with BAV were older (46.9 ± 10.4 vs 38.4 ± 14 years, P < .001) and more likely male (89.0% vs 56.4%, P < .001) and hypertensive (66.1% vs 28.7%, P < .001). Preoperative AI was similar (P = .57) between groups (30.3% mild, 18.3% moderate, 11.1% severe). Most patients had no/trivial immediate postoperative residual AI (96.3% vs 93.1%). Operative mortality was zero; postoperative adverse events were minimal. Mean clinical follow-up was 5.2 ± 4.4 years; 10-year survival was 95.6% versus 95.7% (P = .70). Echocardiographic follow-up was 3.9 ± 4.1 years; incidence of >2+ AI (9.7% vs 10.1%, P = 1.0) was similar between groups, whereas the incidence of moderate or greater aortic stenosis was greater with BAV (7.5% vs 0%, P = .02). Reoperation was low in both groups (3.7% vs 5.9%, P = .65). Competing risk analysis found no difference in reoperation hazard between BAV and CTD groups (hazard ratio, 0.36; 95% confidence interval, 0.07-1.81, P = .21). CONCLUSIONS: Patients with BAV and CTD have excellent operative outcomes, no mortality, and minimal residual AI after VSRR. Although the incidence of recurrent AI was similar, patients with BAV are at risk for AS.
RESUMEN
INTRODUCTION: The Charlson Comorbidity Index (CCI) is widely utilized for risk stratification for non-cardiac surgical patients, yet it has not been broadly validated in patients undergoing cardiac surgery. We aim to assess its ability to predict early and late outcomes of concomitant mitral valve intervention with ascending aortic surgery. METHODS: Patients who underwent surgery between 1997 and 2022 were reviewed. Age-adjusted CCI scores were calculated based on clinical status at a time of index operation. The primary endpoint was all causes mortality while secondary outcomes were major adverse events (MAE) that included combined perioperative mortality, dialysis, myocardial infarction, and stroke in addition to the individual outcomes and take back for bleeding and tracheostomy. Chi-square test, Logistic and Cox regression analysis, and Kaplan-Meier curves were used. Maximally selected rank statistics were used to identify best cutoff of CCI for late mortality. RESULTS: 186 patients (median age 65 [interquartile range (IQR): 54-76] and 69% males) were included with a median CCI of 4 [IQR: 3-6]. Five and ten-years overall survival were 95.9% and 67.1% vs 59.7%, and 19.9% in CCI ≤ 5 vs >5 (P < 0.001). On multivariate Cox regression analysis, higher CCI (HR 1.60 [1.17;2.18], P = 0.00), and lower EF (HR 0.89 [0.83;0.96], P = 0.002) were associated with late mortality. There was a trend to lower mortality in recent surgery years (HR 0.91 [0.83;1.01], P = 0.070)). Perioperative MAE was higher in CCI >5 (11.0% vs 2.1%, P = 0.017), and postoperative need for tracheostomy and CVA had a trend to be higher in CCI > 5 (P = 0.055). Logistic regression revealed that higher CCI, as a continuous variable, was associated with significantly higher odds of MAE, postoperative dialysis, and need for tracheostomy. CONCLUSIONS: The CCI can be a helpful tool in predicting outcomes of patients undergoing concomitant mitral valve intervention with ascending aortic surgery.
RESUMEN
BACKGROUND: We compared the outcomes of aortic root replacement by composite valve grafts (CVG) and valve-sparing root replacement (VSRR) operations, with an emphasis on postoperative conduction block and the need for permanent pacemaker implantation (PPM). METHODS: From 1997 to 2023, 1712 consecutive patients underwent ARR by VSRR (501 [29%]) or CVG (1211 [71%]) at a high-volume aortic center. RESULTS: Patients undergoing CVG were older (59 ± 14 vs 49 ± 14 years, P < .001), with more cardiovascular comorbidities. Compared with CVG, there were more women undergoing VSRR (17% vs. 13%, P = .042) and more patients with connective tissue disease (22% vs 7.3%, P < .001). Multivariable analysis found that the risk for PPM was higher after CVG compared with VSRR (6.5% vs 1.2%; odds ratio [OR], 2.83; 95% CI, 1.23-7.69; P = .024). Other variables associated with PPM include older age (OR, 1.03; 95% CI, 1.01-1.05; P = .006) preoperative renal impairment (OR, 2.69; 95% CI, 1.24-5.6; P = .010), previous operation (OR, 2.76; 95% CI, 1.29-5.62; P = .007), and bicuspid aortic valve (OR, 3.63; 95% CI, 2.13-6.33; P < .001). Among the CVG population, patients who are at increased risk are especially those with some degree of aortic stenosis (OR, 2.06; 95% CI, 1.18-3.61; P = .011). Patients who required PPM had no additive risk for long-term mortality (hazard ratio, 1.01; 95% CI, 0.47-2.17; P = .986); however, they were more likely to have reduced ejection fraction (29.3% vs 16%, P = .014). CONCLUSIONS: The incidence of PPM after ARR is low, but rates were higher after CVG compared with VSRR.
RESUMEN
Importance: The overall prevalence of mitral valve replacement (MVR) or MV repair at the time of cardiac surgery in the setting of isolated anterior mitral leaflet degenerative pathologic status in the US population is unknown. Objective: To investigate the prevalence of MVR and MV repair using the Society of Thoracic Surgeons' Adult Cardiac Surgery Database. Design, Setting, and Participants: In a cross-sectional study, all patients diagnosed with isolated anterior mitral leaflet degenerative regurgitation who underwent either surgical MVR or MV repair between July 1, 2011, and June 30, 2022, were identified. Linear regression analysis was used to assess trends over time. Main Outcomes and Measures: Assessment of the trends in MV repair and MVR over time. Results: A total of 16â¯259 patients (9624 [59.2%] men) were identified, and the median age was 68 (IQR, 58-74) years. A total of 7214 patients (44.4%) had MVR, and 9045 (55.6%) had MV repair. There was a declining trend of MV repair from 58.0% in 2011 to 51.6% in 2022 (P = .05). The MVR group was older (median [IQR] age, 70 [62-77] vs 67 [58-74] years; P < .001) and had more comorbidities. A total of 85.1% of all patients underwent concomitant procedures. In 81.7% of MVR cases, no attempt at MV repair was made. The median (IQR) annual hospital volume was lower with MVR vs MV repair (2.50 [1.50-5.00] vs 4.00 [2.00-7.00]; P < .001). Conventional surgical approaches were most common (91.5%) but with a declining trend (P < .001). Minimally invasive approaches were used in 13.1% (robotic, 4.6%), and with an inclining trend from 5.0% in 2011 to 12.0% in 2022 (P < .001). Annuloplasty was performed in 88.8% of MV repair cases. Its use as a sole mean of MV repair decreased from 48.0% in 2011 to 13.9% in 2022 (P < .001). Repair maneuvers in addition to annuloplasty were neochordae (overall 40.1%, increasing from 22.5% in 2011 to 62.3% in 2022; P < .001), leaflet resection (overall 10.2%, decreasing from 13.1% in 2011 to 7.9% in 2022, P = .002), edge-to-edge MV repair (overall 5.3%, decreasing from 6.9% in 2011 to 4.5% in 2022; P = 0.04), and chordal transfer (overall 2.4%, decreasing from 2.7% in 2011 to 0.7% in 2022; P = .004). Conclusions and Relevance: In this cross-sectional study, MV repair was the preferred option for degenerative mitral valve disease but was only slightly more commonly performed than MVR for isolated anterior leaflet pathologic status. A large proportion of MVR was performed without an MV repair attempt, suggesting reluctance to repair this pathologic condition.

OBJECTIVES: Midline sternotomy is the main surgical access for cardiac surgeries. The most prominent complication of sternotomy is sternal wound infection (SWI). The use of a thorax support vest (TSV) that limits thorax movement and ensures sternal stability has been suggested to prevent postoperative SWI. METHODS: We performed a meta-analysis to evaluate differences in clinical outcomes with and without the use of TSV after cardiac surgery in randomized trials. The primary outcome was deep SWI (DSWI). Secondary outcomes were superficial SWI, sternal wound dehiscence, and hospital length of stay (LOS). A trial sequential analysis was performed. Fixed (F) and random effects (R) models were calculated. RESULTS: A total of 4 studies (3820 patients) were included. Patients who wore the TSV had lower incidence of DSWI [odds ratio (OR) = F: 0.24, 95% confidence interval (CI), 0.13-0.43, P < 0.01; R: 0.24, 0.04-1.59, P = 0.08], sternal wound dehiscence (OR = F: 0.08, 95% CI, 0.02-0.27, P < 0.01; R: 0.10, 0.00-2.20, P = 0.08) and shorter hospital LOS (standardized mean difference = F: -0.30, -0.37 to -0.24, P < 0.01; R: -0.63, -1.29 to 0.02, P = 0.15). There was no difference regarding the incidence of superficial SWI (OR = F: 0.71, 95% CI, 0.34-1.47, P = 0.35; R: 0.64, 0.10, 4.26, P = 0.42). The trial sequential analysis, however, showed that the observed decrease in DSWI in the TSV arm cannot be considered conclusive based on the existing evidence. CONCLUSIONS: This meta-analysis suggests that the use of a TSV after cardiac surgery could potentially be associated with a reduction in sternal wound complications. However, despite the significant treatment effect in the available studies, the evidence is not solid enough to provide strong practice recommendations.
RESUMEN
Immune-checkpoint inhibitors (ICIs) were proven effective in inducing tumor regression. However, its toxicity tends to be fatal. We sought to investigate the hospital volume/outcomes relationship. Databases were searched for studies reporting immune-checkpoint inhibitors adverse events (AEs) in patients with solid-organ malignancies. The outcomes were A) the pooled events rate (PER) of grade 5, grade 3-4, cardiac-related, and pulmonary-related AEs, and B) the assessment of the volume/outcomes relationship. One hundred and forty-seven studies met our inclusion criteria. The PER of grade 5, grade 3-4, and any-grade AEs was 2.75% (95%CI: 2.18-3.47), 26.69% (95%CI: 21.60-32.48), and 77.80% (95%CI: 70.91-83.44), respectively. The PER of pulmonary-related AEs was 4.56% (95%CI: 3.76-5.53). A higher number of annual cases per center was significantly associated with reduced grade 5 (p = 0.019), grade 3-4 (p = 0.004), and cardiac-related AEs (p = 0.035) in the meta-regression. In the current era of cancer immunotherapy, knowledge regarding the early diagnosis and management of immunotherapy-related AEs is essential. Our meta-analysis demonstrates the importance of center volume in improving outcomes and reducing the incidence of severe AEs.
RESUMEN
BACKGROUND: Women undergoing coronary artery bypass grafting (CABG) have higher operative mortality than men. OBJECTIVES: The purpose of this study was to evaluate the relationship between intraoperative anemia (nadir intraoperative hematocrit), CABG operative mortality, and sex. METHODS: This was a cohort study of 1,434,225 isolated primary CABG patients (344,357 women) from the Society of Thoracic Surgeons Adult Cardiac Surgery Database (2011-2022). The primary outcome was operative mortality. The attributable risk (AR) (the risk-adjusted strength of the association of female sex with CABG outcomes) for the primary outcome was calculated. Causal mediation analysis derived the total effect of female sex on operative mortality risk and the proportion of that effect mediated by intraoperative anemia. RESULTS: Women had lower median nadir intraoperative hematocrit (22.0% [Q1-Q3: 20.0%-25.0%] vs 27.0% [Q1-Q3: 24.0%-30.0%], standardized mean difference 97.0%) than men. Women had higher operative mortality than men (2.8% vs 1.7%; P < 0.001; adjusted OR: 1.36; 95% CI: 1.30-1.41). The AR of female sex for operative mortality was 1.21 (95% CI: 1.17-1.24). After adjusting for nadir intraoperative hematocrit, AR was reduced by 43% (1.12; 95% CI: 1.09-1.16). Intraoperative anemia mediated 38.5% of the increased mortality risk associated with female sex (95% CI: 32.3%-44.7%). Spline regression showed a stronger association between operative mortality and nadir intraoperative hematocrit at hematocrit values <22.0% (P < 0.001). CONCLUSIONS: The association of female sex with increased CABG operative mortality is mediated to a large extent by intraoperative anemia. Avoiding nadir intraoperative hematocrit values below 22.0% may reduce sex differences in CABG operative mortality.

BACKGROUND: Both valve-sparing root replacement and composite valve graft (CVG) are acceptable options in aortic root replacement. We compare outcomes of these 2 approaches and durability of the aortic valve. METHODS: A consecutive 1635 patients without acute dissection underwent primary aortic root replacement from 1997 to 2022; 473 (29%) underwent valve-sparing root replacement, and 1162 (71%) received CVG. Propensity score matching was used to reduce baseline differences. RESULTS: The CVG group was older (59 ± 14 years vs 49 ± 14 years; P < .001) with more comorbidities, such as hypertension (88.4% vs 66.4%; P < .001), diabetes (7% vs 1.7%; P < .001), ischemic heart disease (5.1% vs 1.3%; P = .001), pulmonary disease (6.6% vs 1.3%; P < .001), renal impairment (8.6% vs 1.3%; P < .001), class III-IV heart failure (35% vs 9.2%; P < .001), bicuspid aortic valves (44.8% vs 24.1%; P < .001), and severe aortic insufficiency (50.2% vs 13.2%; P < .001). Operative mortality was 0.4% (0% in valve sparing); incidence of major postoperative complications was 2.9% (3.6% vs 1.1%; P = .009). Ten-year survival was 93.1% (91.2% vs 97.7%; hazard ratio [HR], 1.7; 95% CI, 0.9-3.3; P = .120). Mean follow-up was 65 ± 60 months; aortic valve reoperations were similar (5.8% vs 5.7%; HR, 0.8; 95% CI, 0.4-1.4; P = .401). Recurrent moderate-severe aortic insufficiency was less prevalent in CVG (6.1% vs 11.1%; HR, 0.14; 95% CI, 0.07-0.27; P < .001). Propensity score matching identified 225 pairs. There was no difference in 10-year survival or reoperations. Recurrent moderate-severe aortic insufficiency was higher with valve sparing. CONCLUSIONS: Both valve-sparing operations and CVG provide excellent early and late outcomes out to 10 years. Valve sparing is associated with a higher risk for development of aortic insufficiency but no difference in reoperations.

BACKGROUND: Biomechanical effects of transcatheter (TAVR) versus surgical (SAVR) aortic valve interventions on the distal aorta have not been studied. This study utilized global circumferential strain (GCS) to assess post-procedural biomechanics changes in the descending aorta after TAVR versus SAVR. METHODS: Patients undergoing TAVR or SAVR for aortic stenosis were included. Transesophageal (TEE) and transthoracic (TTE) echocardiography short-axis images of the aorta were used to image the descending aorta immediately before and after interventions. Image analysis was performed with two-dimensional speckle tracking echocardiography and dedicated software. Delta GCS was calculated as: post-procedural GCS-pre-procedural GCS. Percentage delta GCS was calculated as: (delta GCS/pre-procedural GCS) × 100. RESULTS: Eighty patients, 40 TAVR (median age 81 y/o, 40% female) and 40 SAVR (median 72 y/o, 30% female) were included. The post-procedure GCS was significantly higher than the pre-procedural GCS in the TAVR (median 10.7 [interquartile range IQR 4.5, 14.6] vs. 17.0 [IQR 6.1, 20.9], p = 0.009) but not in the SAVR group (4.4 [IQR 3.3, 5.3] vs. 4.7 [IQR 3.9, 5.6], p = 0.3). The delta GCS and the percentage delta GCS were both significantly higher in the TAVR versus SAVR group (2.8% [IQR 1.4, 6] vs. 0.15% [IQR - 0.6, 1.5], p < 0.001; and 28.8% [IQR 14.6%, 64.6%] vs. 4.4% [IQR - 10.6%, 5.6%], p = 0.006). Results were consistent after multivariable adjustment for key clinical and hemodynamic characteristics. CONCLUSIONS: After TAVR, there was a significantly larger increase in GCS in the distal aorta compared to SAVR. This may impact descending aortic remodeling and long-term risk of aortic events.

The external stenting of saphenous vein grafts (SVGs) during coronary artery bypass grafting (CABG) has been proven to reduce intimal hyperplasia (IH) in animal models, paving the way for human randomized controlled trials (RCTs) to be conducted. Herein, we performed a study-level meta-analysis to assess the impact of the Venous External SupporT (VEST) device, an external stent, on the outcomes of SVGs. A systematic search was conducted to identify all RCTs comparing VEST-stented to non-stented SVGs in patients undergoing CABG. The primary outcome was graft occlusion. The main secondary outcomes were repeat revascularization, SVG IH area, and intimal-medial thickness. Two RCTs totaling 407 patients were included. At a mean follow-up of 1.5 years, there was no difference in graft occlusion between groups (incidence rate ratio: 1.11; 95% confidence interval (CI): 0.80-1.53). The rate of repeat revascularization was also similar (odds ratio: 0.66; 95% CI: 0.27-1.64). The IH area (standardized mean difference (SMD): -0.45; 95% CI: -0.79 to -0.10) and intimal-medial thickness (SMD: -0.50; 95% CI: -0.90 to -0.10) were significantly reduced in the VEST group. Our findings show that significant reductions in the IH area and the intimal-medial thickness in VEST-stented SVGs do not currently translate into a lesser need for repeat revascularization or less graft occlusion events compared to non-stented SVGs at 1.5 years after CABG.
RESUMEN
OBJECTIVE: To review the available literature on the use of coronary artery bypass grafting (CABG) as a treatment option for anomalous origin of coronary artery in adults. METHODS: A systematic literature search was performed in March 2023 (including Ovid MEDLINE, Ovid Embase, and the Cochrane Library databases) to identify studies reporting the use of CABG in adult patients with anomalous origin of coronary artery. RESULTS: A total of 31 studies and 62 patients were included, 32 patients (52%) were women, and the mean age was 45.1±16.1 years. The most common coronary anomaly was the right coronary artery arising from the left coronary sinus in 26 patients (42%), followed by an anomalous left coronary artery from the pulmonary artery in 23 patients (37%). A total of 65 conduits were used in 61 patients, and 1 case report did not report conduit type. Reported grafts included saphenous vein (23 of 65 [35.4%]), left internal thoracic artery (15 of 65 [23.1%]), right internal thoracic artery (23 of 65 [35.4%]), and radial artery (2 of 65 [3.1%]); right gastroepiploic artery and basilic vein were used once (1.5%) each. Ligation of the native coronary artery was performed in 42 (67.7%) patients. Patient follow-up was available in 19 studies with a mean of 31.2 months. Only 1 operative mortality was reported. CONCLUSIONS: Based on the limited available data, CABG can be performed with good early results. Use of arterial conduits and ligation of the native coronary artery may improve long-term graft patency.

Saphenous vein grafts (SVGs) are the most frequently used conduits in coronary artery bypass grafting (CABG), but their higher rate of occlusion compared to arterial conduits remains a concern. Previous studies have shown that SVG failure is mainly driven by intimal hyperplasia, an adaptative response to higher pressures of the arterial circulation. The VESTTM device (Vascular Graft Solutions, Tel Aviv, Israel), an external support designed to mitigate intimal hyperplasia in SVGs, has been tested in few clinical trials (RCTs). Herein, we descriptively evaluated the randomized evidence on the VEST device.
RESUMEN
BACKGROUND: With preventive aortic grafting decreasing the incidence of type A dissections in Marfan syndrome (MFS), most dissections are now type B, for which risk factors remain largely uncertain. OBJECTIVES: We explored the determinants of type B dissection risk in a large, single-center MFS registry. METHODS: Demographic and anthropometric features, cardiovascular disease, and surgical history were compared in patients with MFS with and without type B dissection. RESULTS: Of 336 patients with MFS, 47 (14%) experienced a type B dissection (vs type A in 9%). Patients with type B dissection were more likely to have undergone elective aortic root replacement (ARR) (79 vs 46%; P < 0.001). Of the patients, 55% had type B dissection a mean of 13.3 years after ARR, whereas 45% experienced type B dissection before or in the absence of ARR; 41 patients (87%) were aware of their MFS diagnosis before type B dissection. Among those with predissection imaging, the descending aorta was normal or minimally dilated (<4.0 cm) in 88%. In multivariable analyses, patients with type B dissection were more likely to have undergone ARR and independent mitral valve surgery, to have had a type II dissection, and to have lived longer. CONCLUSIONS: In our contemporary cohort, type B dissections are more common than type A dissections and occur at traditional nonsurgical thresholds. The associations of type B dissection with ARR, independent mitral valve surgery, and type II dissection suggest a more severe phenotype in the setting of prolonged life expectancy.
RESUMEN
Aims: Postoperative atrial fibrillation (POAF) is the most common complication of cardiac surgery and has been associated with increased postoperative morbidity and hospital costs. The Posterior left pericardiotomy for the prevention of AtriaL fibrillation After Cardiac Surgery (PALACS) trial found that posterior pericardiotomy significantly reduced the incidence of POAF (17% vs. 32%, P < 0.001). We present the protocol for The Effect of Posterior Pericardiotomy on the Incidence of Atrial Fibrillation After Cardiac Surgery-Extended Follow-Up study (PALACS-EF): a prospective, extended follow-up of the original PALACS trial. The aim of PALACS-EF is to gain more data regarding the effect of posterior pericardiotomy on postdischarge clinical outcomes. The primary outcome is the time to the first occurrence of the composite of all-cause mortality or hospital cardiovascular readmission. The key secondary outcome is the time to the first occurrence of the composite of all-cause mortality and all-cause hospital readmission. Hospital readmission, myocardial infarction, stroke, transient ischaemic attack, heart failure, systemic embolism, or new arrhythmias with onset since 30-day follow-up will also be recorded. Methods and results: All 420 patients enrolled in the PALACS trial will be included; extended follow-up will be conducted via telephone by blinded research personnel utilizing a standardized script to ensure uniformity and completeness of follow-up. If an event has occurred, documentation will be obtained, and an independent adjudication committee blinded to group assignment will adjudicate outcome events. Results will be reported when a median follow-up of 5 years is achieved. Conclusion: PALACS-EF will provide data to answer the question of whether posterior pericardiotomy improves postdischarge outcomes in patients undergoing cardiac surgery, and it will provide information on the relationship between POAF and adverse postdischarge outcomes including mortality, hospitalization, heart failure, and stroke.

RESUMEN
As a result of increasing adoption of imaging screening, the number of adult patients with a diagnosis of anomalous aortic origin of the coronary arteries (AAOCA) has grown in recent years. Existing guidelines provide a framework for management and treatment, but patients with AAOCA present with a wide range of anomalies and symptoms that make general recommendations of limited applicability. In particular, a large spectrum of interventions can be used for treatment, and there is no consensus on the optimal approach to be used. In this paper, a multidisciplinary group of clinical and interventional cardiologists and cardiac surgeons performed a systematic review and critical evaluation of the available evidence on the interventional treatment of AAOCA in adult patients. Using a structured Delphi process, the group agreed on expert recommendations that are intended to complement existing clinical practice guidelines.
