Article Synopsis
  • Heart transplantation is the most effective treatment for advanced heart failure, but due to limited organ donation, many patients rely on left ventricular assist device (LVAD) implantation as a temporary solution.
  • A study of 68 advanced heart failure patients showed that those using the HeartMate 3 LVAD had better survival rates and fewer complications compared to those using the HeartWare device.
  • Out of the patients studied, 35 successfully received heart transplants, and the study highlighted the importance of reliable LVADs in improving patient outcomes while waiting for transplantation.

Article Synopsis
  • Infective endocarditis (IE) is a severe complication after valve replacement surgeries, occurring in 1.8% to 5.8% of cases, with up to 20% in-hospital mortality; common pathogens include Streptococci, Staphylococcus aureus, Enterococci, and fungi.
  • The treatment for IE often requires lengthy antibiotic courses, and cases involving aortic prosthetic valves may need complex surgical interventions due to root abscess formations.
  • A recent case series from Greece reported successful outcomes in 8 patients who underwent surgery for prosthetic valve endocarditis with significant aortic root abscesses, highlighting the effectiveness of using aortic homografts for aortic root replacement in these challenging

The perioperative management of patients with pulmonary hypertension (PH) undergoing cardiac surgery is challenging, mainly due to the potential risk of right ventricular failure (RVF). Levosimendan is a calcium-sensitizing agent that has primarily been used in the treatment of decompensated heart failure. However, recently levosimendan has been shown to be an effective and safe therapeutic strategy for patients with pulmonary arterial hypertension and PH associated with left heart disease.

Introduction: The perioperative management of patients with pulmonary hypertension (PH) undergoing cardiac surgery represents one of the most challenging clinical scenarios. This fact mainly depends on the relationship existing between PH and right ventricular failure (RVF). Levosimendan (LS) is an inodilator that might be an effective agent in the treatment of PH and RVF.

We report two cases of transient intraoperative mydriasis in left ventricular assist device (LVAD) patients with no profound underlining neurological pathology. Both cases concern females on LVAD for more than 30 months, due to dilated cardiomyopathy, as a bridge to transplant. A possible pathophysiology mechanism is suggested.

Pediatric cardiac anesthesia is a subspecialty of cardiac and pediatric anesthesiology dedicated to the perioperative care of patients with congenital heart disease. Members of the Congenital and Education Subcommittees of the European Association of Cardiothoracic Anaesthesiology and Intensive Care (EACTAIC) agreed on the necessity to develop an EACTAIC pediatric cardiac anesthesia fellowship curriculum. This manuscript represents a consensus on the composition and the design of the EACTAIC Pediatric Cardiac Anesthesia Fellowship program.

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.

This special article summarizes the design and certification process of the European Association of Cardiothoracic Anesthesiology (EACTA) Cardiothoracic and Vascular Anesthesia (CTVA) Fellowship Program. The CTVA fellowship training includes a two-year curriculum at an EACTA-accredited educational facility. Before fellows are accepted into the program, they must meet a number of requirements, including evidence of a valid license to practice medicine, a specialist degree examination in anesthesiology, and appropriate language skills as required in the host centers.

This article reviews fellowship training in adult cardiac, thoracic, and vascular anesthesia and critical care from the perspective of European program initiators and educational leaders in these subspecialties together with current training fellows. Currently, the European Association of Cardiothoracic Anaesthesiology (EACTA) network has 20 certified fellowship positions each year in 10 hosting centers within 7 European countries, with 2 positions outside Europe (São Paulo, Brazil). Since 2009, 42 fellows have completed the fellowship training.

Background: Composite graft replacement of the aortic root is the treatment of choice for an array of aortic root pathologies, such as annuloaortic ectasia, Marfan syndrome and acute or chronic aortic dissection type A. In this retrospective study of the authors' aortic surgery database, an exploration was made of factors related to early and long-term morbidity and mortality of patients who underwent this procedure.

Methods: Between 2000 and 2009, a total of 200 consecutive patients (male:female ratio 4:1; mean age 56.

Introduction: Hypothermic circulatory arrest is widely used for correction of acute type A aortic dissection pathology. We present our experience of 45 consecutive patients operated in our unit with bilateral antegrade cerebral perfusion and moderate hypothermic circulatory arrest.

Methods: Between January 2011 and April 2015, 45 consecutive patients were admitted for acute type A aortic dissection and operated emergently under moderate hypothermic circulatory arrest and bilateral antegrade cerebral perfusion.

Cardiac papillary fibroelastoma is a rare benign cardiac tumor that represents less than 10% of all cardiac tumors. Most papillary fibroelastomas are relatively small. Symptoms, if present, are due to flow obstruction or peripheral embolization.

Dose the fractured guide wire should be removed during or after percutaneous coronary interventions? In case when the patients have unstable hemodynamic status the fractured guide wire should be removed with percutaneous or surgical method. Antiplatelet drug administration should be considered after procedure to prevention of the coronary artery thrombosis.

Background: Coronary endarterectomy albeit infrequently utilized remains a pivotal treatment modality for advanced atherosclerotic heart disease. Benefits of coronary endarterectomy are explored in terms of better mid-term survival, freedom of major adverse cardiac and cerebrovascular events and improved left ventricular ejection fraction.

Methods: 50 patients with coronary artery disease including extensive diffuse LAD disease underwent a left anterior descending artery endarterectomy with coronary by-pass grafting and left internal mammary artery as conduit between 2006 and 2014.

Background: Over the years, numerous options have been proposed for surgical management of ascending aorta and aortic arch pathology in an attempt to minimize postoperative morbidity and probability of death. We present a propensity score-matching analysis of 259 patients from a single unit who were operated on under deep hypothermic arrest with retrograde cerebral perfusion (DHCA/RCP) or moderate hypothermic circulatory arrest with selective antegrade cerebral perfusion (via common carotid artery) (MHCA/ACP).

Methods: Between 2006 and 2014 a total of 259 consecutive patients underwent ascending aorta and hemiarch correction under HCA.

Background: Pulmonary hypertension and right ventricular (RV) dysfunction may complicate the implantation of a left ventricular assist device (LVAD). We examined whether inhaled vasodilators can sufficiently reduce RV afterload, avoiding the need for temporary RV mechanical support.

Methods: The study includes 7 patients with RV dysfunction after LVAD insertion.

Pulmonary hypertension (PH) is an independent risk factor for increased mortality in patients undergoing heart surgery. Existing chronic PH may be exacerbated by acute post-bypass PH, and this can lead to acute right ventricular failure. The prevention and treatment of right ventricular failure in cardiac surgery is based on three principles: optimize right ventricular preload, improve right ventricular contractility, minimize right ventricular afterload.
