Diabetes is not a negative prognostic factor for 30-days mortality after surgery for acute type A aortic dissection.

Background: The correlation between diabetes and aortic dissection is not fully understood yet, although in literature many studies have suggested that there may be an association between the two conditions. The purpose of this study is to evaluate whether diabetes represents a short- and long-term risk factor for mortality from type A acute aortic dissection.

Materials And Methods: A total of 340 patients with the diagnosis of type A acute aortic dissection underwent aortic surgery between January 2002 and March 2023.

Analysis of current mortality risk scores for acute type A aortic dissection: The Siena experience.

Objective: In literature, various risk scores have been described to predict in-hospital mortality of patients undergoing surgery for acute type A dissection. We want to evaluate which factors are most correlated with a negative outcome and testing the validity of the current scores in literature analyzing our experience of over 20 years in the surgery of type A aortic dissections.

Materials And Methods: A total of 324 patients were included in the study.

Transapical total aortic arch replacement with three-branched endograft for penetrating aortic ulcer.

An 80-year-old man with a chronic penetrating atherosclerotic ulcer was not a candidate for open surgical repair owing to the presence of diffuse vascular atherosclerosis and a deep ulcerative lesion originating at the level of the aortic arch concavity. No appropriate endovascular landing zone was present in arch zones 1 or 2. However, a totally endovascular branched arch repair involving transapical delivery of the three branches was successful.

Intercostal artery's access for type II endoleak embolization.

Endoleaks represent a main issue of endovascular approach of thoracic aorta diseases and their treatment continue to be challenging. According to some authors, type II endoleaks sustained by intercostal arteries should not be treated because of the technical difficulties. However, the persistence of a pressurized aneurysmal may confer an ongoing risk of enlargement and/or aortic rupture.

Left Ventricular Lead Placement for Biventricular Pacing in a Left Lateral Vein in a Patient with Congenital Atresia of the Coronary Sinus Ostium.

Coronary sinus ostial atresia (CSOA) is a rare kind of congenital heart anomaly. This creates a new drainage pathway for the cardiac venous flow, with the most common being a persistent left superior vena cava (PLSVC). During the implantation of a cardiac resynchronization therapy defibrillator, we discovered a case of CSOA in a patient who underwent aortic valve and ascending aorta replacement.

(s)INE: (soft-graft)-induced new entry tear after elephant trunk procedure.

Elephant trunk and frozen elephant trunk are established procedures for the treatment of aortic arch pathologies, such as aneurysm or dissection. The aim of open surgery is to re-expand the true lumen, favouring correct organ perfusion and the thrombosis of the false lumen. Frozen elephant trunk, with its stented endovascular portion, is sometimes associated with a life-threatening complication: the stent graft-induced new entry.

How to perform a direct axillary artery cannulation.

The choice of the arterial cannulation site has been a matter of debate over the years. The femoral artery has been used for a long time due to its ease of isolation and the possibility of percutaneous cannulation. However, it is associated with the risk of embolization because of the retrograde flow, and it is more dangerous in the case of aortic dissection because perfusion is unpredictable and retrograde flow exposes the patient to the risk of malperfusion.

Arch replacement with collared elephant trunks: The Siena approach.

Objective: To illustrate our experience and results in patients with diffuse aneurysmal disease treated with arch replacement using the Siena collared graft, a device designed in 2002 to improve the elephant trunk technique. Results of the first step surgical implant and the subsequent treatment strategies, with extensive use of endovascular techniques, are reported.

Methods: All aortic arch-replacement procedures using the Siena graft between February 2002 and January 2020 were retrospectively analyzed for early and late clinical outcomes.

Intimal re-layering technique for type A acute aortic dissection-reconstructing the intimal layer continuity to induce remodeling of the false channel.

Background: Residual false channel is common after repair of type A acute aortic dissection (TAAAD). Starting from our recent series of TAAAD patients we carried out a retrospective analysis, regarding the failure of primary exclusion at the time of the initial operation. We classified the location of the principal entry tears perfusing the residual false channel.

Emergency fast Bentall operation.

We herein report an emergency technique of composite Bentall operation using a fast release valve. The technique was successfully performed in 2 emergency cases after failed supracoronary ascending aortic replacement in acute Type A aortic dissection. The speed and ease of execution are the main advantages of the procedure.

Trans-pericardal Color Doppler Ultra Sound to Assess Blood Flow in the Visceral Branches during Type A Dissection Procedures Complicated with Mesenteric Malperfusion.

Aortic dissection is a complex disease associated with high mortality and morbidity. Among the different possible clinical presentations, type A aortic dissection complicated at the onset by mesenteric malperfusion is characterized by poor outcome compared with patients not presenting such complication. We report the case of a patient with acute type A aortic dissection presenting with mesenteric malperfusion, in whom trans-pericardial color Doppler ultrasound (CDUS) examination was used to assess intraoperative and postoperative blood flow in the mesenteric artery.

Levosimendan in critical illness: a literature review.

Levosimendan, the active enantiomer of simendan, is a calcium sensitizer developed for treatment of decompensated heart failure, exerts its effects independently of the beta adrenergic receptor and seems beneficial in cases of severe, intractable heart failure. Levosimendan is usually administered as 24-h infusion, with or without a loading dose, but dosing needs adjustment in patients with severe liver or renal dysfunction. Despite several promising reports, the role of levosimendan in critical illness has not been thoroughly evaluated.

Influence of positive end-expiratory pressure on myocardial strain assessed by speckle tracking echocardiography in mechanically ventilated patients.

Purpose: The effects of mechanical ventilation (MV) on speckle tracking echocardiography- (STE-)derived variables are not elucidated. The aim of the study was to evaluate the effects of positive end-expiratory pressure (PEEP) ventilation on 4-chamber longitudinal strain (LS) analysis by STE.

Methods: We studied 20 patients admitted to a mixed intensive care unit who required intubation for MV and PEEP titration due to hypoxia.

Single-center experience and 1-year follow-up results of "sandwich technique" in the management of common iliac artery aneurysms during EVAR.

Purpose: Abdominal aortic aneurysm (AAA) accompanied by common iliac artery (CIA) aneurysms requires a more demanding procedure owing to the difficulties in obtaining an adequate distal landing zone for the stent-graft limb(s), a potential site of endoleak. The "sandwich technique" is a procedure to increase EVAR feasibility in the setting of adverse or challenging CIA anatomy. Its main advantages include no restrictions in terms of CIA diameter or length or internal iliac artery (IIA) diameter, no need to wait for a specific stent-graft.

Successful use of a military haemostatic agent in patients undergoing extracorporeal circulatory assistance and delayed sternal closure.

We report the successful control of bleeding in two patients who underwent post-cardiotomy extracorporeal circulatory support (ECMO) and then developed life-threatening bleeding due to severe coagulopathy. After the failure of conventional techniques, bleeding control was achieved using Celox Gauze (MedTrade Products Ltd, Cheshire, UK) packed on the sternal edges and pericardial cavity.

Continuous cardiac output monitoring with an uncalibrated pulse contour method in patients supported with mechanical pulsatile assist device.

We evaluated the accuracy of an uncalibrated pulse contour method called Pressure Recording Analytical Method (PRAM) compared with continuous thermodilution for cardiac output (CO) monitoring in patients implanted with a pulsatile left ventricular assist device (LVAD). Twelve adult patients implanted with the HeartMate I-XVE device were studied. CO was simultaneously evaluated by PRAM and by continuous thermodilution.

Cardiogenic shock as a complication of acute mitral valve regurgitation following posteromedial papillary muscle infarction in the absence of coronary artery disease.

A 48 year old man was transferred to our department with cardiogenic shock, pyrexia, a high white cell count and significant serum troponin T level. Clinical evaluation revealed severe mitral regurgitation secondary to a flail of both mitral valve leaflets. An emergency cardiac catheterisation did not reveal any significant coronary artery disease.
