RESUMO
OBJECTIVE: Infective endocarditis (IE) caused by Staphylococcus species (spp.) is believed to be associated with higher morbidity and mortality rates. We hypothesize that Staphylococcus spp. are more virulent compared with other commonly causative bacteria of IE with regard to short-term and long-term mortality. BACKGROUND: It remains unclear if patients suffering from IE due to Staphylococcus spp. should be referred for surgical treatment earlier than other IE patients to avoid septic embolism and to optimize perioperative outcomes. MATERIALS AND METHODS: The database of the CAMPAIGN registry, comprising 4917 consecutive patients undergoing heart valve surgery, was retrospectively analyzed. Patients were divided into 2 groups with regard to the identified microorganisms: Staphylococcus group and the non- Staphylococcus group. The non- Staphylococcus group was subdivided for further analyses: Streptococcus group, Enterococcus group, and all other bacteria groups. RESULTS: The respective mortality rates at 30 days (18.7% vs 11.8%; P <0.001), 1 year (24.7% vs 17.7%; P <0.001), and 5 years (32.2% vs 24.5%; P <0.001) were significantly higher in Staphylococcus patients (n=1260) compared with the non- Staphylococcus group (n=1787). Multivariate regression identified left ventricular ejection fraction <30% ( P <0.001), chronic obstructive pulmonary disease ( P =0.045), renal insufficiency ( P =0.002), Staphylococcus spp. ( P =0.032), and Streptococcus spp. ( P =0.013) as independent risk factors for 30-day mortality. Independent risk factors for 1-year mortality were identified as: age ( P <0.001), female sex ( P =0.018), diabetes ( P =0.018), preoperative stroke ( P =0.039), chronic obstructive pulmonary disease ( P =0.001), preoperative dialysis ( P <0.001), and valve vegetations ( P =0.004). CONCLUSIONS: Staphylococcus endocarditis is associated with an almost twice as high 30-day mortality and significantly inferior long-term outcome compared with IE by other commonly causative bacteria. Patients with Staphylococcus infection are more often female and critically ill, with >50% of these patients suffering from clinically relevant septic embolism. Early diagnosis and referral to a specialized center for surgical treatment are strongly recommended to reduce the incidence of preoperative deterioration and stroke due to septic embolism.

OBJECTIVES: Extracorporeal cardiopulmonary resuscitation (eCPR) is increasingly used due to its beneficial outcomes and results compared to conventional CPR. After cardiac arrest, the overall ejection fraction is severely impaired; thus, weaning from ECMO is often prolonged or impossible. We hypothesized that early application of levosimendan in these patients facilitates ECMO weaning and survival. METHODS: From 2016 until 2020, patients who underwent eCPR after cardiac arrest at our institution were analyzed retrospectively and divided into two groups: patients who received levosimendan during ICU stay (n = 24) and those who did not receive levosimendan (n = 84) and analyzed for outcome parameters. Furthermore, we used propensity-score matching and multinomial regression analysis to show the effect of levosimendan on outcome parameters. RESULTS: Overall, in-hospital mortality was significantly lower in the group which received levosimendan (28% vs. 88%, p ≤ 0.01), and ECMO weaning was more feasible in patients who received levosimendan (88% vs. 20%, p ≤ 0.01). CPR duration until ECMO cannulation was significantly shorter in the levosimendan group (44 + 26 vs. 65 + 28, p = 0.002); interestingly, the rate of mechanical chest compressions before ECMO cannulation was lower in the levosimendan group (50% vs. 69%, p = 0.005). CONCLUSION: In patients after cardiac arrest treated with eCPR, levosimendan seems to contribute to higher success rates of ECMO weaning, potentially due to a short to mid-term increase in inotropy. Also, the survival after levosimendan application was higher than patients who did not receive levosimendan.

BACKGROUND AND AIM OF THE STUDY: The management of graft infection following ascending aortic replacement (AAR) and/or aortic valve replacement (AVR) with destruction of the root remains a challenge. Besides technical issues, the choice of graft material is controversial. The study aim was to investigate the initial results of aortic root replacement (ARR) as redo-surgery for infection using the xenopericardial all-biologic conduit (BioIntegral) as an alternative to a homograft or prosthetic material. METHODS: Between February 2013 and January 2015, a total of 18 consecutive patients (16 males, two females; mean age 61 ± 14 years) were reoperated on for infection at a mean of 55 ± 61 months (range: 3 to 219 months) following previous AVR (n = 6), supracoronary aortic replacement (SAR, n = 2), AVR + SAR (n = 1), root replacement (n = 7), and root reconstruction (n = 2). Two patients (11%) had undergone more than one previous cardiac operation. Signs of infection were seen on computed tomography (CT) scanning in 17 patients (94%). Additional 18F-FDG PET-CT was performed in nine patients (50%). RESULTS: The cardiopulmonary bypass and crossclamp were 289 ± 77 min and 187 ± 59 min, respectively. Hypothermic circulatory arrest (HCA) + selective antegrade cerebral perfusion (SACP) was necessary in nine patients (50%) and concomitant procedures in 11 (61%). Postcardiotomy extracorporeal life support (ECLS) was necessary in five patients, and renal replacement therapy in eight. One patient died intraoperatively, and the overall 30-day mortality was 22% (n = 4) secondary to multi-organ failure. Risk factors for mortality were myocardial failure requiring ECLS (p = 0.02) and the need for root replacement following previous isolated AVR (p = 0.05). The mean follow up was 12 ± 5 months. Early graft reinfection occurred in one patient (6%), and another presented with pleural empyema without evidence of persisting conduit infection. Thus, freedom from graft reinfection was 94%. No case of structural valve deterioration was seen. CONCLUSIONS: Aortic root replacement using a xenopericardial conduit in patients with graft infection is technically feasible. Hemodynamics and surgical handling are comparable to that of homografts, but the off-the-shelf availability favors this approach. Mortality was substantial but comparable to that of other series and grafts, with low reinfection rates. Long-term outcome regarding the eradication of infection and durability of the graft remains to be demonstrated.

Paraplegia remains the most devastating complication of open and endovascular thoracic/thoracoabdominal aortic aneurysm (TAA/A) repair. However, the assessment of currently available neuromonitoring modalities remains challenging and difficult to interpret. Near-infrared spectroscopy (NIRS) has been introduced as a strategy for noninvasive, real-time monitoring of the paraspinous collateral network (CN) to detect potential spinal cord ischemia at our institution. Prior to TAA/A repair, a cerebrospinal fluid catheter is placed and four NIRS optodes are bilaterally positioned on the patient's back to transcutaneously monitor regional muscle oxygenation at the thoracic and lumbar levels. Indirect surveillance of the spinal cord by NIRS seems to be a tempting option with increasing evidence supporting the CN concept.

BACKGROUND: The choice of the best conduit for root/ascending disease and its impact on longevity remain controversial in quinquagenarians. METHODS AND RESULTS: A total of 205 patients (men=155) between 50 and 60 years (mean, 55.7 ± 2.9 years) received either a stentless porcine xenoroot (n=78) or a mechanically valved composite prosthesis (n=127) between February 1998 and July 2011. Of these, 166 patients underwent root replacement for aneurysmal disease (porcine: 39% [n=65]; mechanical: 61% [n=101]; P=0.5), 25 for acute type A aortic dissection (porcine: 32% [n=8]; mechanical: 68% [n=17]; P=0.51), and 14 for endocarditis/iatrogenic injury involving the aortic root (6.4% [n=5] versus 7.1% [n=9]; P=1.0). The predominant aortic valve pathology was stenosis in 19% (n=38), regurgitation in 50% (n=102), combined valvular dysfunction in 26% (n=54), and normal aortic valve function in 5% (n=11). Concomitant procedures included coronary artery bypass grafting (13%), mitral valve repair (7%), and partial/complete arch replacement (12%/4%), with no significant differences between porcine and mechanical root replacement. Overall hospital mortality was 7.3%, with no difference between the 2 types of valve prostheses (7.7% for porcine and 7.1% for mechanical root replacement; P=1.0). Follow-up averaged 5.4 ± 3.7 years (1096 patient-years) and was 100% complete. Freedom from aorta-related reoperation at 12 years was not statistically different between the groups (porcine: 94.9% versus mechanical: 96.1%; P=0.73). Survival was equivalent between both groups, with a 5-year survival of 86 ± 3% (porcine: 88 ± 4%; mechanical: 85 ± 3%; P=0.96) and a 10-year survival of 76% (porcine: 80 ± 7%; mechanical: 75 ± 5%; P=0.84). The linearized mortality rate was 3.1%/patient-year (porcine: 2.9%/patient-year; mechanical: 3.2%/patient-year). CONCLUSIONS: In quinquagenerians, long-term survival after stentless porcine xenograft aortic root replacement is equivalent to that after a mechanical Bentall procedure. These results bring into question the predominance of mechanical composite conduits for root replacement in quinquagenerians, particularly in the current era of transcatheter valve-in-valve procedures for structural valve deterioration.

OBJECTIVES: The indications for use, evidence base and experience with the novel noncovered open hybrid surgical stents for acute type A aortic dissection repair for concurrent stabilization of the 'downstream' aorta remains limited. We review the evidence base and the development of these stents. METHODS: Data were collected from Pubmed/Medline literature search to develop and review the evidence base for safety and efficacy of non-covered surgical stents. Existing guidelines for use and developments were reviewed. RESULTS: A single randomized control trial and 4 single-centre studies were included in the review with a total worldwide experience of 241 patients. The deployment was easy and did not add significantly to the primary operation. The mortality and new stroke ranged from 6.3-18.7%. Safe and complete deployment was accomplished in 92-100%. There was no device-related reintervention. There was a significant improvement in malperfusion in over 90% of the cases with varying degrees of remodelling (60-90%) of the downstream aorta. CONCLUSIONS: Open noncovered stent grafts represent a major technical advancement as an adjunct procedure for acute dissection repairs, e.g. hemiarch repair. It has potential for wider use by non-aortic surgeons due to simplicity of technique. Limited safety and efficacy data confirm the device to be safe, feasible and reproducible with potential for wider adoption. However, long-term trial and registry data are required before recommendations for standard use outside of high-volume experienced aortic centres.

Objectives: Extracorporeal cardiopulmonary resuscitation (ECPR) is increasingly used due to its beneficial outcomes and results compared to conventional CPR. Cardiac arrests can be categorized depending on location: in-hospital cardiac arrest (IHCA) and out-of-hospital cardiac arrest (OHCA). Despite this distinction, studies comparing the two are scarce, especially in comparing outcomes after ECPR. This study compared patient characteristics, cardiac arrest characteristics, and outcomes. Methods: Between 2016 and 2022, patients who underwent ECPR for cardiac arrest at our institution were retrospectively analyzed, depending on the arrest location: IHCA and OHCA. We compared periprocedural characteristics and used multinomial regression analysis to indicate parameters contributing to a favorable outcome. Results: A total of n = 157 patients (100%) were analyzed (OHCA = 91; IHCA = 66). Upon admission, OHCA patients were younger (53.2 ± 12.4 vs. 59.2 ± 12.6 years) and predominantly male (91.1% vs. 66.7%, p=<0.001). The low-flow time was significantly shorter in IHCA patients (41.1 ± 27.4 mins) compared to OHCA (63.6 ± 25.1 mins). Despite this significant difference, in-hospital mortality was not significantly different in both groups (IHCA = 72.7% vs. OHCA = 76.9%, p = 0.31). Both groups' survival-to-discharge factors were CPR duration, low flow time, and lactate values upon ECMO initiation. Conclusion: Survival-to-discharge for ECPR in IHCA and OHCA was around 25%, and there was no statistically significant difference between the two cohorts. Factors predicting survival were lower lactate levels before cannulation and lower low-flow time. As such, OHCA patients seem to tolerate longer low-flow times and thus metabolic impairments compared to IHCA patients and may be considered for ECMO cannulation on a broader time span than IHCA.
RESUMO
The treatment of DeBakey type I aortic dissection remains a major challenge in the field of aortic surgery. To upgrade the standard of care hemiarch replacement, a novel device called an "Ascyrus Medical Dissection Stent" (AMDS) is now available. This hybrid device composed of a proximal polytetrafluoroethylene cuff and a distal non-covered nitinol stent is inserted into the aortic arch and the descending thoracic aorta during hypothermic circulatory arrest in addition to hemiarch replacement. Due to its specific design, it may result in a reduced risk for distal anastomotic new entries, the effective restoration of branch vessel malperfusion and positive aortic remodeling. In this narrative review, we provide an overview about the indications and the technical use of the AMDS. Additionally, we summarize the current available literature and discuss potential pitfalls in the application of the AMDS regarding device failure and aortic re-intervention.
RESUMO
OBJECTIVES: To date, there are no standardized treatment algorithms or recommendations for patients with infective endocarditis (IE) and concomitant spondylodiscitis (SD). Therefore, our aim was to analyse whether the sequence of surgical treatment of IE and SD has an impact on postoperative outcome and to identify risk factors for survival and postoperative recurrence. METHODS: Patients with IE underwent surgery in 4 German university hospitals between 1994 and 2022. Univariable and multivariable analyses were performed to identify possible predictors of 30-day/1-year mortality and recurrence of IE and/or SD. RESULTS: From the total IE cohort (n = 3991), 150 patients (4.4%) had concomitant SD. Primary surgery for IE was performed in 76.6%, and primary surgery for SD in 23.3%. The median age was 70.0 (64.0-75.6) years and patients were mostly male (79.5%). The most common pathogens detected were enterococci and Staphylococcus aureus followed by streptococci, and coagulase-negative Staphylococci. If SD was operated on first, 30-day mortality was significantly higher than if IE was operated on 1st (25.7% vs 11.4%; P = 0.037) and we observed a tendency for a higher 1-year mortality. If IE was treated 1st, we observed a higher recurrence rate within 1 year (12.2% vs 0%; P = 0.023). Multivariable analysis showed that primary surgery for SD was an independent predictor of 30-day mortality. CONCLUSIONS: Primary surgical treatment for SD was an independent risk factor for 30-day mortality. When IE was treated surgically 1st, the recurrence rate of IE and/or SD was higher.

OBJECTIVES: The aim of this multicentre study was to demonstrate the safety and clinical performance of E-vita OPEN NEO Stent Graft System (Artivion, Inc.) in the treatment of aneurysm or dissection, both acute and chronic, in the ascending aorta, aortic arch and descending thoracic aorta. METHODS: In this observational study of 12 centres performed in Europe and in Asia patients were enrolled between December 2020 and March 2022. All patients underwent frozen elephant trunk using E-vita OPEN NEO Stent Graft System. Primary end point was the rate of all-cause mortality at 30 days and secondary end points included further clinical and safety data are reported up to 3-6 months postoperatively. RESULTS: A total of 100 patients (66.7% male; mean age, 57.7 years) were enrolled at 12 sites. A total of 99 patients underwent surgery using the E-vita OPEN NEO for acute or subacute type A aortic dissection (n = 37), chronic type A aortic dissection (n = 33) or thoracic aortic aneurysm (n = 29), while 1 patient did not undergo surgery. Device technical success at 24 h was achieved in 97.0%. At discharge, new disabling stroke occurred in 4.4%, while new paraplegia and new paraparesis was reported in 2.2% and 2.2%, respectively. Renal failure requiring permanent (>90 days) dialysis or hemofiltration at discharge was observed in 3.3% of patients. Between discharge and the 3-6 months visit, no patients experienced new disabling stroke, new paraplegia or new paraparesis. The 30-day mortality was 5.1% and the estimated 6-month survival rate was 91.6% (standard deviation: 2.9). CONCLUSIONS: Total arch replacement with the E-vita OPEN NEO can be performed with excellent results in both the acute and chronic setting. This indicates that E-vita OPEN NEO can be used safely, including in the setting of acute type A aortic dissection.

OBJECTIVES: Sex-related differences play a role in cardiovascular disease-related outcomes. There is, however, a knowledge gap regarding sex-specific differences in patients with infective endocarditis (IE)-requiring surgical treatment. This study aims to analyse sex-related differences in the clinical presentation, treatment and clinical outcomes of patients with IE-requiring surgical treatment from the multicentric Germany-wide CAMPAIGN registry. METHODS: Patients with IE who underwent cardiac surgery between 1994 and 2018 at six German centres were retrospectively analysed. Outcomes were compared based on patients' sex. Primary outcomes were 30-day mortality and mid-term survival. RESULTS: A total of 4917 patients were included in the analysis (1364 female [27.7%] and 3553 male [72.3%]). Female patients presented with more comorbidities and higher surgical risk (EuroScore II 12.0% vs 10.0%, P < 0.001). The early postoperative course of female patients was characterized by longer ventilation times (20.0 h vs 16.0 h; P = 0.004), longer intensive care unit stay (4.0 days vs 3.0 days; P < 0.001), and more frequent new-onset dialysis (265 [20.3%] vs 549 [16.3%]; P = 0.001). The 30-day mortality was 13.8% and 15.5% in female and male patients, respectively (P = 0.06). The estimated mid-term survival was significantly higher amongst male patients (56.1% vs 45.4%; Log-rank P < 0.001). Female sex was an independent predictor of mid-term mortality (HR 1.2 [95% CI 1.0-1.4], P = 0.01). CONCLUSIONS: Male patients more frequently undergo cardiac surgery for IE. However, female patients have a higher surgical risk profile and subsequently an increased early postoperative morbidity, but with similar 30-day mortality compared with male patients. The estimated mid-term survival is lower amongst female patients.

OBJECTIVES: This study aimed to analyse the impact of preoperative septic cerebral embolism on early and late postoperative outcomes in patients with infective endocarditis undergoing valve surgery. METHODS: Retrospective multicentric study based on the Clinical Multicentric Project for Analysis of Infective Endocarditis in Germany (CAMPAIGN) registry comprising patients with infective endocarditis who underwent valve surgery between 1994 and 2018 at 6 German centres. Patients were divided into 2 groups for statistical comparison according to the presence or absence of preoperative septic cerebral embolism. Propensity score matching was performed for adjusted comparisons of postoperative outcomes. Primary outcomes were 30-day mortality and estimated 5-year survival. RESULTS: A total of 4917 patients were included in the analysis, 3909 (79.5%) patients without and 1008 (20.5%) patients with preoperative septic cerebral embolism. Patients with preoperative septic cerebral embolism had more baseline comorbidities. Mitral valve endocarditis (44.1% vs 33.0% P < 0.001), large vegetations >10 mm (43.1% vs 30.0%, P < 0.001), and Staphylococcus species infection (42.3% vs 21.3%, P < 0.001) were more frequent in the cerebral embolism group. Among patients with preoperative cerebral embolism, 286 (28.4%) patients had no stroke signs (silent stroke). After matching (1008 matched pairs), there was no statistically significant difference in 30-day mortality (20.1% vs 22.8%; P = 0.14) and 5-year survival (47.8% vs 49.1%; stratified log-rank P = 0.77) in patients with and without preoperative cerebral embolism, respectively. CONCLUSIONS: Preoperative septic cerebral embolism in patients with infective endocarditis requiring valve surgery does not negatively affect early or late mortality; therefore, it should not play a major role in deciding if surgery is to be performed.

(1) Background: This study aimed to morphologically analyze acute type A aortic dissection (aTAAD) patients for potential endovascular treatment candidates. The objective was to specify requirements for aTAAD endovascular devices. (2) Methods: A single-center retrospective analysis included aTAAD patients who underwent open surgical repair between November 2005 and December 2020. Preoperative CTA scans were used for morphological analysis, assessing endovascular repair eligibility. Statistical tests were performed. (3) Results: A total of 129 patients with aTAAD were studied, with 119 included. Entry tear (ET) locations were identified, mainly in the aortic root, 20 mm above the sinotubular junction (STJ) and within the ascending aorta (20 mm above STJ to -20 mm before the brachiocephalic trunk). Endovascular treatment was deemed feasible for 36 patients, with suggested solutions for the aortic arch and descending aorta. Significant differences were observed between eligible and noneligible groups for aortic diameter, false lumen diameter, distance between STJ and entry tear, and more. Dissection extension showed no significant difference. (4) Conclusions: Morphological analysis identified potential aTAAD candidates for endovascular treatment, highlighting differences between eligible and noneligible morphologies. This study offers insights for implementing endovascular approaches in aTAAD treatment and emphasizes the need for research and standardized protocols.
RESUMO
A 52-year-old woman presented dyspnea and angina. The computed tomography scan indicated an intramural hematoma, and the patient underwent surgery, during which a structure was excised that was identified as aortic paraganglioma. This case report underlines the importance of a multiprofessional interdisciplinary team to diagnose and treat cardiac masses. (Level of Difficulty: Advanced.).
RESUMO
BACKGROUND: Around the world, survival rates after cardiac arrest range between <14% for in-hospital (IHCA) and <10% for outof- hospital cardiac arrest (OHCA). This situation could potentially be improved by using extracorporeal membrane oxygenation (ECMO) during cardiopulmonary resuscitation (CPR), i.e. by extracorporeal cardiopulmonary resuscitation (ECPR). METHODS: A selective literature search of Pubmed and Embase using the searching string ((ECMO) OR (ECLS)) AND (ECPR)) was carried out in February 2023 to prepare an up-to-date review of published trials comparing the outcomes of ECPR with those of conventional CPR. RESULTS: Out of 573 initial results, 12 studies were included in this review, among them three randomized controlled trials comparing ECPR with CPR, involving a total of 420 patients. The survival rates for ECPR ranged from 20% to 43% for OHCA and 20% to 30.4% for IHCA. Most of the publications were associated with a high degree of bias and a low level of evidence. CONCLUSION: ECPR can potentially improve survival rates after cardiac arrest compared to conventional CPR when used in experienced, high-volume centers in highly selected patients (young age, initial shockable rhythm, witnessed cardiac arrest, therapy-refractory high-quality CPR). No general recommendation for the use of ECPR can be issued at present.

OBJECTIVES: The Ascyrus Medical Dissection Stent (AMDS) has been recently introduced as an alternative for total arch replacement in acute aortic dissection type A (AADA). The aim of this study was to evaluate the postoperative outcomes after AMDS treatment in a large contemporary cohort of AADA patients. METHODS: Data acquisition was performed retrospectively at 2 German aortic centres between 2020 and 2022 and comprised the perioperative parameters and postoperative results of all AADA patients. All patients treated with the AMDS for AADA were included in the study. The primary end point was in-hospital mortality. Secondary end points were defined as early postoperative and AMDS-related complications. RESULTS: Fifty-seven AADA patients treated by AMDS were included in the study group. The mean age was 64.6 ± 10.8 years and 59.7% (n = 34) were males. The actual in-hospital mortality was considerably lower than the predicted mortality risk by the German registry for acute aortic dissection type A score (16% vs 22%). The median ICU and in-hospital stay were 5 (interquartile range: 3-13) and 12 (interquartile range: 10-22) days, respectively. Postoperative complications comprised acute renal insufficiency (37%) with need for temporary (16%) or permanent dialysis (5%), delirium (26%), re-exploration for bleeding (14%), tracheostomy (14%) and new stroke (4%). A new AMDS-related complication (central stent collapse) was observed in 9% (n = 5) by postoperative computed tomography and chest X-ray. The incidence of complete central AMDS collapse did not impact 30-day mortality. CONCLUSIONS: The AMDS may be successfully used in AADA with acceptable 30-day mortality in accordance with the German registry for acute aortic dissection type A score. However, careful preoperative evaluation of the patient's individual aortic anatomy regarding potential contraindications and proper device implantation are strongly recommended to avoid complete central AMDS collapse.

OBJECTIVES: Cardiac tumors are a rare and heterogeneous entity, with a cumulative incidence of up to 0.02%. This study aimed to investigate one of the largest patient cohorts for long-term outcomes after minimally-invasive cardiac surgery using right-anterior thoracotomy and femoral cardiopulmonary bypass (CPB) cannulation. METHODS: Between 2009 and 2021, patients who underwent minimally-invasive cardiac tumor removal at our department were included. The diagnosis was confirmed postoperatively by (immune-) histopathological analysis. Preoperative baseline characteristics, intraoperative data, and long-term survival were analyzed. RESULTS: Between 2009 and 2021, 183 consecutive patients underwent surgery for a cardiac tumor at our department. Of these, n = 74 (40%) were operated on using a minimally-invasive approach. The majority, n = 73 (98.6%), had a benign cardiac tumor, and 1 (1.4%) had a malignant cardiac tumor. The mean age was 60 ± 14 years, and n = 45 (61%) of patients were female. The largest group of tumors was myxoma (n = 62; 84%). Tumors were predominantly located in the left atrium in 89% (n = 66). CPB-time was 97 ± 36min and aortic cross-clamp time 43 ± 24 min s. The mean hospital stay was 9.7 ± 4.5 days. The perioperative mortality was 0%, and all-cause mortality after ten years was 4.1%. CONCLUSION: Minimally-invasive tumor excision is feasible and safe, predominantly in benign cardiac tumors, even in combination with concurrent procedures. Patients who require cardiac tumor removal should be evaluated for minimally-invasive cardiac surgery at a specialized center, as it is highly effective and associated with good long-term survival.

OBJECTIVES: Age-related atherosclerosis has been shown to cause aortic stiffness and wall rigidification. This analysis aimed to correlate age and dissection extension length in a large contemporary multicentre study. We hypothesize that younger patients suffer more extensive DeBakey type I dissection due to aortic wall integrity, allowing unhindered extension within the layers. METHODS: The perioperative data of 3385 patients from the German Registry for Acute Aortic Dissection Type A were retrospectively analyzed with regard to postoperative outcomes and dissection extension. Patients with DeBakey type I aortic dissection (n = 2510) were retrospectively identified and divided into 2 age groups for comparison: ≤69 years (n = 1741) and ≥70 years (n = 769). Patients with DeBakey type II dissection or connective tissue disease were excluded from the analysis. RESULTS: In younger patients (≤69 years), aortic dissection involved the supra-aortic vessels significantly more often (52.0% vs 40.1%; P < 0.001) and extended significantly further downstream the aorta: descending aorta (68.4% vs 57.1%; P < 0.001), abdominal aorta (54.6% vs 42.1%; P < 0.001) and iliac bifurcation (36.6% vs 26.0%; P < 0.001). Consequently, younger patients also presented with significantly higher incidences of preoperative cerebral (P < 0.001), spinal (P < 0.001), visceral (P < 0.001), renal (P = 0.013) and peripheral (P < 0.001) malperfusion. In older patients (≥70 years), dissection extent was significantly more often limited to the level of the aortic arch (40.9% vs 29.2%; P < 0.001). No significant difference was found with regard to 30-day mortality (20.7% vs 23.6%; P = 0.114). CONCLUSIONS: Extensive DeBakey type I aortic dissection is less frequent in older patients ≥70 years than in younger patients. In contrast, younger patients suffer more often from preoperative organ malperfusion and associated complications. Postoperative mortality remains high irrespective of age groups.

OBJECTIVES: The prevalence and aetiology of acute aortic dissection type A (AADA) in patients ≤30 years is unknown. The aims of this clinical study were to determine the prevalence and potential aetiology of AADA in surgically treated patients ≤30 years and to evaluate the respective postoperative outcomes in this selective group of patients in a large multicentre study. METHODS: Retrospective data collection was performed at 16 participating international aortic institutions. All patients ≤30 years at the time of dissection onset were included. The postoperative results were analysed with regard to connective tissue disease (CTD). RESULTS: The overall prevalence of AADA ≤30 years was 1.8% (139 out of 7914 patients), including 51 (36.7%) patients who were retrospectively diagnosed with CTD. Cumulative postoperative mortality was 8.6%, 2.2% and 1.4%. Actuarial survival was 80% at 10 years postoperatively. Non-CTD patients (n = 88) had a significantly higher incidence of arterial hypertension (46.6% vs 9.8%; P < 0.001) while AADA affected the aortic root (P < 0.001) and arch (P = 0.029) significantly more often in the CTD group. A positive family history of aortic disease was present in 9.4% of the study cohort (n = 13). CONCLUSIONS: The prevalence of AADA in surgically treated patients ≤30 years is <2% with CTD and arterial hypertension as the 2 most prevalent triggers of AADA. Open surgery may be performed with good early results and excellent mid- to long-term outcomes.

Objectives: As surgical experience with infective endocarditis following transcatheter aortic valve replacement is scarce, this study compared the perioperative and short-term outcomes of patients suffering from endocarditis following surgical aortic valve replacement and transcatheter aortic valve replacement. Methods: Between January 2013 and December 2020, 468 consecutive patients were admitted to our center for surgery for IE. Among them, 98 were operated on for endocarditis following surgical aortic valve replacement and 22 for endocarditis following transcatheter aortic valve replacement. Results: The median EuroSCORE II (52.1 (40.6-62.0) v/s 45.4 (32.6-58.1), p = 0.207) and STS-PROM (1.8 (1.6-2.1) v/s 1.9 (1.4-2.2), p = 0.622) were comparable. Endocarditis following transcatheter aortic valve replacement accounted for 13.7% of the aortic prosthetic valve endocarditis between 2013 and 2015; this increased to 26.9% in the years 2019 and 2020.Concomitant procedures were performed in 35 patients (29.2%). The operative mortality was 26.5% in the endocarditis following surgical aortic valve replacement group and 9.1% in the endocarditis following transcatheter aortic valve replacement group (p = 0.098). Upon follow-up, survival at 6 months was found to be 98% in the group with endocarditis following surgical aortic valve replacement and 89% in the group with endocarditis following transcatheter aortic valve replacement (p = 0.081). Conclusions: Patients suffering from endocarditis following surgical aortic valve replacement and transcatheter aortic valve replacement present with comparable risk profiles and can be surgically treated with comparable results. Surgery as a curative option should not be rejected even in this intermediate-risk cohort.
