Introduzione: La disfunzione epato-renale costituisce un fattore di rischio per mortalità e morbidità postoperatoria nei candidati a trapianto. Il MELD-XI (Model of End-Stage Liver Disease Excluding INR) score rappresenta un valido strumento per valutare in anticipo i pazienti affetti da scompenso cardiaco avanzato. Scopo della nostra analisi è stato valutare l’impatto, come fattore prognostico, di valori progressivamente maggiori del MELD-XI score nei pazienti sottoposti a trapianto di cuore. Metodi: Fra gennaio 2000 ed agosto 2016 un totale di 425 pazienti consecutivi sono stati sottoposti a trapianto presso la nostra unità operativa. I dati di questa coorte di pazienti, dopo stratificazione in base al MELD-XI score (MELD-XI 18), sono stati analizzati per descrivere i risultati a breve ed a lungo termine. Risultati: I pazienti con MELD-XI score >18 sono caratterizzati da condizioni cliniche preoperatorie critiche, che determinano un rischio di mortalità precoce maggiore (HR 1.45 [1.11-1.67], p 18 è rispettivamente 63% e 47%, contro il 72% e 59% del gruppo di controllo (MELD-XI, Introduction: Preoperative liver and renal dysfunction remain surgical risk factors for both postoperative morbidity and mortality. The ‘Model of End-Stage Liver Disease Excluding INR’ score (MELD-XI) calculation may help as predictor in patients with advanced heart failure. We analyzed the impact of progressive elevated MELD-XI values among heart transplant recipients at our institution. Methods: The data of a total of 425 consecutive adult patients who underwent heart transplantation, between January 2000 and August 2018, have been reviewed and divided into three cohorts according to preoperative MELD-XI calculations (MELD-XI 18). Early and late outcomes have been analyzed. Results: Patients with MELD-XI score >18 had a more critical clinical condition preoperatively and resulted to have a higher risk of early mortality (HR 1.45 [1.11-1.67], p 240 minutes resulted the strongest predictors of early mortality (p0.001). The 5-y and 10-y survival for MELD-XI >18 cohort was 63% and 47% versus 72% and 59% in the control group (MELD-XI

Background This study assessed the early and long-term results of arch operations performed after a prior aortic operation. Methods From 1994 to 2014, 154 consecutive patients (mean age, 59.7 years) underwent an aortic arch repair, after a previous aortic operation, at our institution. Antegrade selective cerebral perfusion was used in all cases. Chronic postdissection aortic aneurysm (87 [56.5%]) and degenerative aneurysm (43 [27.9%]) represented the most common indications for surgical intervention. A complete arch replacement was performed in 119 patients (77.3%), an associated root repair in 70 (45.5%), and the frozen elephant trunk technique was used in 55 (35.7%). Results Hospital mortality was 11.7% (n = 18). Postoperative permanent neurologic dysfunction occurred in 10 patients (6.4%). On multivariate analysis, cardiopulmonary bypass time (odds ratio, 1.02 per minute; p = 0.005) emerged as the only independent predictor of hospital death. Follow-up was 100% complete. The estimated survival at 1, 5, and 10 years was 79.6%, 69.9%, and 46.8%, respectively. Freedom from reoperation was 75.6% at 5 years and 54.6% at 10 years. Cox regression identified chronic postdissection aortic aneurysm (odds ratio, 4.2; p = 0.006) to be the only independent predictor of aortic reintervention. Late survival was comparable between degenerative aneurysm patients and the Italian population matched for age and sex (standardized mortality ratio, 1.9; p = 0.1). Longevity was reduced in patients operated on for chronic postdissection aortic aneurysm (standardized mortality ratio, 6.3; p Conclusions Arch operations after a previous open aortic repair can be performed with acceptable mortality and good long-term outcomes. Complete aortic resection did not increase hospital deaths and was associated with a low need for aortic reinterventions at follow-up.

Objectives Aortic root replacement using a composite graft is the treatment of choice for a large variety of aortic root conditions with a diseased aortic valve. The objective of the current study was to evaluate the long-term results of this procedure. Methods Between 1978 and 2010, 1045 patients aged 58.7 ± 13.6 years underwent aortic root composite graft replacement using the following techniques: 95 Bentall operation; 926 the “button technique;” 24 the Cabrol technique. A mechanical composite valve graft was implanted in 69.6% of the patients. Six-hundred and thirty-five patients (62.3%) had annuloaortic ectasia and 162 (15.5%) had aortic dissection. Results Early mortality was 5.3% (55/1045). Independent risk factors for early mortality at logistic regression analysis were age ≥70 years (P = .051; odds ratio [OR], 2.97), New York Heart Association III-IV (P = .052; OR, 1.88), reoperation (P = .021; OR, 2.36), urgency/emergency (P = .003; OR, 3.09), mitral valve replacement (P = .001; OR, 6.01), or coronary artery bypass grafting (CABG) (P
