Central versus peripheral VA ECMO for cardiogenic shock: an 8-year experience of a tertiary cardiac surgery center in Greece.

Background: Venoarterial extracorporeal membrane oxygenation (VA ECMO) has emerged as an effective rescue therapy in patients with cardiogenic shock refractory to standard treatment protocols, and its use has been rising worldwide in the last decade. Although experience and availability are growing, outcomes remain poor. There is need for evidence to improve clinical practice and outcomes.

Klotho as an Early Marker of Acute Kidney Injury Following Cardiac Surgery: A Systematic Review.

Acute kidney injury is a common complication following cardiac surgery (CSA-AKI). Serum creatinine levels require a minimum of 24-48 h to indicate renal injury. Nevertheless, early diagnosis remains critical for improving patient outcomes.

Endovascular Treatment of Type A Aortic Dissection: A Systematic Review and Meta-Analysis Using Reconstructed Time-to-Event Data.

Objective: The undisputed gold standard of treatment for type A aortic dissections (TAAD) is open surgery. Anecdotal reports have assessed thoracic endovascular aortic repair (TEVAR) as a last resort for highly selected candidates. The present study aims to evaluate endovascular outcomes in TAAD patients who are unsuitable for open surgery whilst having TEVAR-compatible aortic anatomy.

Anomalous circumflex artery: a benign variant generating a malignant potential after valve surgery.

Coronary artery anomalies are a diverse group of congenital disorders presenting with highly variable clinical manifestations. The anomalous origin of left circumflex artery from the right coronary sinus following a retro-aortic trajectory is a well-recognized anatomic variation. Despite its benign course, it can prove lethal in association with valvular surgery.

Infected thoracic aortic graft in a woman with Darier disease: a case report.

Background: Patients with Darier disease often present with staphylococcal skin infections and are at risk for complications when they undergo cardiothoracic surgery, such as acute aortic dissection repair.

Case Summary: A 39-year-old woman with hypertension and Darier disease suffered an acute type A aortic dissection, requiring emergency operation with a Dacron graft. Twenty-five days post-operatively, she developed pneumonia and staph hominis was isolated in blood cultures and Bronchoalveolar Lavage.

The effect of paracorporeal pulsatile biventricular assist devices on allosensitization in adults: A comparison with left ventricular assist devices.

Ventricular assist devices (VADs) have been associated with the development of anti-HLA antibodies ('allosensitization'), but data on devices providing biventricular support in adults are limited. We sought to characterize differences in anti-HLA antibody formation in adult patients receiving left- (LVAD) versus biventricular- (BiVAD) assist devices as bridge to transplantation (BTT) by retrospectively reviewing the records of adult patients who have undergone VAD implantation at our institution. We assessed 82 patients supported with a pulsatile-flow paracorporeal BiVAD and compared them with 40 patients receiving LVAD till 2018.

A modern approach to aortic valve insufficiency: Aortic root restoration via HAART 300 internal annuloplasty ring.

Background And Aim Of The Study: HAART 300 is an internal geometric annuloplasty ring. The safety and efficacy of this novel device in aortic valve (AV) repair in a single referral center are reported.

Methods: Twenty patients with trileaflet AV insufficiency with ascending aorta and/or aortic root enlargement were included.

Multiple-valve Repair Facilitated by Aortic Ring Annuloplasty.

Early and late outcomes of patients undergoing multiple-valve procedures are better if all valves are repaired. Aortic/mitral multiple-valve repair has been limited by an inability to repair the more complex forms of aortic valve insufficiency. With the development of aortic ring annuloplasty 90% to 95% of aortic valve insufficiency pathologies now can be repaired, which opens most aortic/mitral multiple-valve procedures to the better repair outcomes.

Antegrade and Retrograde Cerebral Perfusion During Acute Type A Aortic Dissection Repair in 290 Patients.

Aim: Hypothermia and selective brain perfusion is used for brain protection during an acute type A aortic dissection (ATAAD) correction. We compared the outcomes between antegrade and retrograde cerebral perfusion techniques after ATAAD surgery.

Method: Between January 1995 and August 2017, 290 patients underwent ATAAD repair under deep hypothermic circulatory arrest/retrograde cerebral perfusion (DHCA/RCP) in 173 patients and moderate hypothermic circulatory arrest/antegrade cerebral perfusion (MHCA/ACP) in 117 patients.

Q Fever Endocarditis and a New Genotype of Coxiella burnetii, Greece.

Underdiagnosis of Coxiella burnetii infections in Greece is possible because of lack of awareness by physicians, and most suspected cases are in patients with no bovine contact. We found serologic evidence of C. burnetii infection throughout Greece and identified a new C.

Toll-like receptor 9 and the inflammatory response to surgical trauma and cardiopulmonary bypass.

Objectives: Cardiac surgery can lead to post-operative end-organ complications secondary to activation of systemic inflammatory response. We hypothesize that surgical trauma or cardiopulmonary bypass (CPB) may initiate systemic inflammatory response via release of mitochondrial DNA (mtDNA) signaling Toll-like receptor 9 (TLR9) and interleukin-6 production (IL-6).

Materials And Methods: The role of TLR9 in systemic inflammatory response in cardiac surgery was studied using a murine model of sternotomy and a porcine model of sternotomy and CPB.

Extremely low therapeutic doses of acenocoumarol in a patient with and genotype.

Vitamin-K antagonists (VKAs) have remained the mainstay of oral anticoagulant therapy for the treatment and prevention of thromboembolism. The management of treatment with VKAs is challenging due to their narrow therapeutic index and the wide interindividual variation in response to therapy. Variants of the and the gene account for 30-50% of the variability in dosing requirements, and it has been proposed that genotyping of these loci could facilitate management of VKA therapy and minimize risk of overanticoagulation, even in very low doses.

68-year-old woman with paroxysmal atrial fibrillation.

We present the case of a 68-year-old woman, currently asymptomatic but with a history of paroxysmal atrial fibrillation and tachycardia-bradycardia syndrome, for which she underwent a DDD pacemaker implantation and was started on oral anticoagulants. A recent chest X-ray (figure 1), for respiratory infection, was performed and the patient was referred to our institution for evaluation. Following diagnostic procedures, the patient was successfully operated on.

Clinical presentation and treatment of cardiac myxoma in 153 patients.

Cardiac myxoma (CM) is the most common benign cardiac tumor. We retrospectively reviewed our single center experience in 153 patients with CM over a period 25 years.From November 1993 to May 2017, 153 patients were operated in our institution with diagnosis of a CM.

What is the optimal target for the second arterial graft in patients undergoing coronary bypass surgery?

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether the anterolateral or the inferior wall served as a better location for the 2nd arterial graft in a 3-system coronary artery bypass grafting procedure. In total, more than 1800 papers were found, of which 6 represented the best evidence to answer the clinical question.

Objective: The objective of this study was to examine the validity of EuroSCORE II in the Greek population.

Methods: A prospective single-center study was performed during November 1, 2013 and November 5, 2016; 621 patients undergoing cardiac surgery were enrolled. The EuroSCORE II values and the actual mortality of the patients were recorded in a special database.

Complete Shrinkage of the Obliterated False Lumen After Open and Endovascular Chronic Aortic Dissection Stanford Type A Repair.

A 48-year-old man was admitted to our hospital with chronic aortic dissection Stanford Type A. His diagnosis was confirmed by chest multi-detector computed tomography (CT). The patient underwent combined (i.

A systematic review of left ventricular cardio-endoscopic surgery.

Better visualisation, accurate resection and avoidance of ventriculotomy associated with use of endoscopic devices during intracardiac surgery has led to increasing interest in their use. The possibility of combining a cardio-endoscopic technique with either minimally invasive or totally endoscopic cardiac surgery provides an incentive for its further development. Several devices have been used, however their uptake has been limited due to uncertainty around their impact on patient outcomes.

Trans-aortic endoscopic ventricular thrombectomy in a patient with HIT and concomitant Aortic and ventricular thromboses.

Dual aortic and ventricular thrombi are rare following myocardial infraction. We report the case of a 56-year-old man who initially denied primary percutaneous coronary intervention as a result of psychological phobia. Initial pharmacological management by thrombolysis and heparin was followed by multiple arterial thromboses including those of the left ventricle and right iliac artery with a subsequent diagnosis of heparin-induced thrombocytopaenia.

Gender Analysis in the Outcomes of a Lifestyle Intervention Among Patients Who Had an Open Heart Surgery.

Unlabelled: The aim of this study was to evaluate the gender-oriented differences in the outcomes of a lifestyle intervention trial (diet, smoking cessation, and exercise) among patients who had open heart surgery. A randomized, nonblind intervention study was performed on 500 patients who had open heart surgery. Immediately after hospital discharge, 250 patients were randomly allocated lifestyle intervention by receiving oral and written information in the form of a booklet with specific educational information for postoperative rehabilitation.

Perioperative use of iloprost in cardiac surgery patients diagnosed with heparin-induced thrombocytopenia-reactive antibodies or with true HIT (HIT-reactive antibodies plus thrombocytopenia): An 11-year experience.

Thrombocytopenia and thromboembolism(s) may develop in heparin immune-mediated thrombocytopenia (HIT) patients after reexposure to heparin. At the Onassis Cardiac Surgery Center, 530 out of 17,000 patients requiring heart surgery over an 11-year period underwent preoperative HIT assessment by ELISA and a three-point heparin-induced platelet aggregation assay (HIPAG). The screening identified 110 patients with HIT-reactive antibodies, out of which 46 were also thrombocytopenic (true HIT).
