OBJECTIVES: No reliable scores are available to predict mortality following surgery for type A acute aortic dissection (TAAAD). Recently, the German Registry of Acute Aortic Dissection Type A (GERAADA) score has been developed. We aim to compare how the GERAADA score performs in predicting operative mortality for TAAAD to the European System for Cardiac Operative Risk Evaluation (EuroSCORE) II. METHODS: We calculated the GERAADA score and EuroSCORE II in patients who underwent TAAAD repair at the Bristol Heart Institute. As there are no precise criteria to calculate the GERAADA score, we used 2 methods: a Clinical-GERAADA score, which evaluated malperfusion with clinical and radiological evidence, and a Radiological-GERAADA score, where malperfusion was assessed by computed tomography scan alone. RESULTS: 207 consecutive patients had surgery for TAAAD, and the observed 30-day mortality was 15%. The Clinical-GERAADA score showed the strongest discriminative power with an area under the curve (AUC) of 0.80 [95% confidence interval (CI) 0.71–0.89], while the Radiological-GERAADA score had an AUC of 0.77 (95% CI 0.67–0.87). EuroSCORE II showed acceptable discriminative power with an AUC of 0.77 (95% CI 0.67–0.87). CONCLUSIONS: Clinical GERAADA score performed better than the other scores and it is specific and easy to use in the context of a TAAAD. Further validation of the new criteria for malperfusion is needed.

OBJECTIVES: The goal of this multicentre retrospective study was to compare long-term clinical and haemodynamic outcomes of the Carpentier-Edwards Magna Ease (CEME) bioprosthesis by patient age.METHODS: We included consecutive patients who underwent isolated and combined surgical aortic valve replacement (AVR) with CEME valve between January 2008 and March 2020 at 4 cardiac surgery centres in Italy. Survival distribution was evaluated at follow-up according to age and surgery type (combined or isolated AVR), together with freedom from structural valve deterioration (SVD), reoperation and combined events, i.e. SVD, reoperation, endocarditis and thromboembolic events.RESULTS: A total of 1027 isolated and 1121 combined AVR were included; 776 patients were younger than 65 years whereas 1372 were 65 years or older. The 30-day Valve-Academic-Research-Consortium mortality was 2% (<65 years) and 6% (≥ 65 years) (P < 0.001), whereas it was 3% for isolated AVR and 7% for combined AVR (P < 0.001). The 12-year survival was 81% for those younger than 65 years vs 45% for those equal to or older than 65 years (P < 0.001), whereas they were 61% vs 49% for isolated and combined AVR (P = 0.10). The 12-year freedom from combined events, excluding death, was 79% for those younger than 65 years vs 87% for those equal to or older than (P = 0.51), whereas they were 83% for isolated and 86% for combined AVR (P = 0.10). The 12-year freedom from SVD was 93% and 93% in patients younger than 65 and those equal to or older than 65 years (P = 0.63), and the results were comparable even in cases with isolated and combined AVR (92% vs 94%, P = 0.21). A multivariable Cox analysis including gender, presence of patient–prosthesis mismatch, isolated AVR and age showed that only the age was an independent risk factor for the incidence of SVD (P = 0.029).CONCLUSIONS: Outcomes from this large multicentre analysis demonstrated that a CEME bioprosthesis provides good clinical results and long-term durability even in patients younger than 65 years. Furthermore, the hazard for SVD has been shown to be lower for older age.Clinical trial registration number: 105n/AO/21.

Objectives Ventricular septal defect (VSD) is becoming a progressively less frequent mechanical complication of myocardial infarction (MI). However, this event is still associated with high operative mortality. We aimed to describe the trends and the risk factors associated with surgical VSD repair outcomes and to provide a clinical benchmark for percutaneous VSD closure strategies. Methods Using the UK National Adult Cardiac Surgery Audit database, we identified 1010 patients undergoing surgical VSD repair from 1996 to 2018. The primary outcome was operative mortality. Mixed-model, multivariable logistic regression was used to identify the risk factors associated with operative mortality taking into account the variation related to the centre, the surgeon and the year of the operation. Results Both the number of surgical VSD repair and the mortality rate did not change significantly over the 23-year timeframe. Operative mortality was 38.9% overall and was higher when patients were operated within the first 6 h (75%) or the first 24 h (61.3%) from the index MI. Risk factors associated with higher odds of mortality were early surgery, older age, cardiogenic shock, renal failure, previous percutaneous coronary intervention and urgent/emergent operations. Moreover, the mortality rate was similar among patients undergoing isolated VSD repair and VSD repaired combined with surgical coronary revascularization alone or with concomitant mitral valve procedures. Conclusions Post MI VSD remains a dreaded mechanical complication characterized by high surgical operative mortality. A delayed operation, whenever possible, appears to be the most beneficial strategy to reduce mortality.
