    Abstract We report the case of a 36-year-old European female patient presenting with a sinus valsalva aneurysm of 47 mm with moderate aortic regurgitation. Additionally, an aneurysm of the brachiocephalic trunk and multiple aneurysms of the right internal mammary artery were identified. Previous medical history included Loeys-Dietz syndrome (LDS) Type RII due to a TGF-beta receptor mutation, and beta thalassemia minor with a baseline hemoglobin of 9,3 g/dL on admission.Reconstruction of the aortic root and hemiarch replacement was performed in circulatory arrest under moderate hypothermia. During surgery, hypothermia was required as part of the cerebral protection strategy. We aim to highlight special considerations and discuss the effects of cooling, rewarming and the use of cardiopulmonary bypass (CPB) during extensive surgery in a patient with LDS and beta thalassemia minor.

    Abstract Background: An optimal donor work-up to exclude preexisting conditions is recommended, but urgency and technical equipment in donor centers must be considered. We report a case of two coronary stents present in the donor heart and the related long-term outcome.
    Case presentation: A 59-year-old European male patient suffering from dilated cardiomyopathy with severely reduced left ventricular function and presenting with NYHA III underwent cardiac transplantation in 2004. At the one-year follow-up, during routine cardiac catheterization, two stents were found, one in the right coronary artery and one in the circumflex artery, in the patient's transplanted heart. As no stent implantation was performed since transplantation, these were present prior to transplantation and had been transplanted without causing clinical signs. One of the stents showed in-stent restenosis, and the patient received an additional stent 7 years after transplantation. The other stent still showed a good result, and no further intervention has been required so far. The patient is currently in good clinical condition.
    Conclusion: This is the first case report of favorable long-term stented coronary arteries prior to transplantation. This case highlights the importance of the donor work-up and meticulous palpation of the coronary arteries during donor evaluation.

    Abstract Background: Postoperative atrial fibrillation (POAF) occurs in up to 40% of patients undergoing cardiac surgery. Invasive stimulation of the vagal nerve previously demonstrated a reduced risk of POAF. Therefore, we examined the antiarrhythmic and anti-inflammatory effects of noninvasive low-level transcutaneous electrical stimulation (LLTS) of the greater auricular nerve in a pilot trial including patients undergoing cardiac surgery.
    Methods: Patients were randomized into a sham (n=20) or a treatment group (n=20) for LLTS. After cardiac surgery, electrodes were applied in the triangular fossa of the ear. Stimulation (amplitude 1 mA, frequency 1 Hz for 40 minutes, followed by a 20 minutes break) was performed for up to 2 weeks after cardiac surgery. Heart rhythm was recorded continuously using an ECG during the observation period. CRP (C-reactive protein) and IL (interleukin)-6 plasma concentrations were measured immediately after surgery as well as on day 2 and 7 postsurgery.
    Results: Patients receiving LLTS had a significantly reduced occurrence of POAF (4 of 20) when compared with controls (11 of 20,
    Conclusions: LLTS of the greater auricular nerve may be a potential therapy for POAF. We demonstrated the feasibility to conduct a randomized trial of neurostimulation as an outlay for a multisite clinical trial.

    Abstract Objective- HO-1 (heme oxygenase-1) induction may prevent or reduce ischemia-reperfusion injury. We previously evaluated its in vivo induction after a single systemic administration of heme arginate in peripheral blood mononuclear cells. The current trial was designed to assess the pharmacological tissue induction of HO-1 in the human heart with heme arginate in vivo. Approach and Results- Patients planned for conventional aortic valve replacement received placebo (n=8), 1 mg/kg (n=7) or 3 mg/kg (n=9) heme arginate infused intravenously 24 hours before surgery. A biopsy of the right ventricle was performed directly before aortic cross-clamping and after cross-clamp release. In addition, the right atrial appendage was partially removed for analysis. HO-1 protein and mRNA concentrations were measured in tissue samples and in peripheral blood mononuclear cells before to and up to 72 hours after surgery. No study medication-related adverse events occurred. A strong, dose-dependent effect on myocardial HO-1 mRNA levels was observed (right ventricle: 7.9±5.0 versus 88.6±49.1 versus 203.6±148.7; P=0.002 and right atrium: 10.8±8.8 versus 229.8±173.1 versus 392.7±195.7; P=0.001). This was paralleled by a profound increase of HO-1 protein concentration in atrial tissue (8401±3889 versus 28 585±10 692 versus 29 022±8583; P<0.001). Surgery and heme arginate infusion significantly increased HO-1 mRNA concentration in peripheral blood mononuclear cells ( P<0.001). HO-1 induction led to a significant increase of postoperative carboxyhemoglobin (1.7% versus 1.4%; P=0.041). No effect on plasma HO-1 protein levels could be detected. Conclusions- Myocardial HO-1 mRNA and protein can be dose-dependently induced by heme arginate. Protective effects of this therapeutic strategy should be evaluated in upcoming clinical trials.

    Abstract Objectives: To evaluate the impact of the coronavirus disease 2019 (COVID-19) pandemic on acute and elective thoracic and abdominal aortic procedures.
    Methods: Forty departments shared their data on acute and elective thoracic and abdominal aortic procedures between January and May 2020 and January and May 2019 in Europe, Asia and the USA. Admission rates as well as delay from onset of symptoms to referral were compared.
    Results: No differences in the number of acute thoracic and abdominal aortic procedures were observed between 2020 and the reference period in 2019 [incidence rates ratio (IRR): 0.96, confidence interval (CI) 0.89-1.04; P = 0.39]. Also, no difference in the time interval from acute onset of symptoms to referral was recorded (<12 h 32% vs > 12 h 68% in 2020, < 12 h 34% vs > 12 h 66% in 2019 P = 0.29). Conversely, a decline of 35% in elective procedures was seen (IRR: 0.81, CI 0.76-0.87; P < 0.001) with substantial differences between countries and the most pronounced decline in Italy (-40%, P < 0.001). Interestingly, in Switzerland, an increase in the number of elective cases was observed (+35%, P = 0.02).
    Conclusions: There was no change in the number of acute thoracic and abdominal aortic cases and procedures during the initial wave of the COVID-19 pandemic, whereas the case load of elective operations and procedures decreased significantly. Patients with acute aortic syndromes presented despite COVID-19 and were managed according to current guidelines. Further analysis is required to prove that deferral of elective cases had no impact on premature mortality.
