OBJECTIVES: Conventional cardiopulmonary bypass is the most commonly used means of artificial circulation in cardiac surgery. However, it suffers from the effects of haemodilution and activation of inflammatory/coagulation cascades. Prime displacement (PD) can offset haemodilution and Mini-Extracorporeal Technology (MIECT) can offset both. So far, no study has compared all of these modalities together; hence, we compared the outcomes of these 3 modalities at our institution. METHODS: This was a retrospective analysis of our cardiac surgical database...

OBJECTIVES: Blood cardioplegia (BCP) can be used in different ways to protect the heart from ischaemia-reperfusion injury during cardiac surgery. Because there could be differences between warm and cold intermittent cardioplegia with or without warm reperfusion, we investigated the influence of 2 blood cardioplegia solutions on cardiac function, metabolism and infarct size in stable and infarcted rat hearts. METHODS: The hearts of 32 male Wistar rats were excised and inserted into a blood-perfused isolated heart apparatus...

OBJECTIVES: In recent years, the use of del Nido (DN) cardioplegia has been reported in single-valve surgery or isolated coronary artery bypass surgery with acceptable outcomes. The reports of its use in more complex adult cardiac procedures, however, have been scarce. METHODS: We enrolled a total of 149 adult patients who underwent heart valve surgery with the use of DN cardioplegia between May 2014 and December 2016. For a benchmark comparison, 892 patients who underwent cardiac valve surgery with blood cardioplegia during the same period served as controls...

OBJECTIVES: During open-heart surgery, the myocardium experiences ischaemia-reperfusion injury. A single bout of moderate, 30-min exercise induces preconditioning and protects the heart from ischaemia-reperfusion injury in rats, but this has never been investigated in humans. We aimed to investigate whether 1 bout of moderate exercise 24 h prior to surgery protects against mitochondrial and cardiac damage. METHODS: Patients scheduled for elective coronary artery bypass were eligible for this pilot study...

An 11-month-old girl with an unbalanced atrioventricular septal defect, coarctation of the aorta and an interrupted inferior vena cava with hemiazygos continuation post-surgical status of coarctation repair and pulmonary artery banding underwent a Kawashima operation. Severe hypoxia occurred immediately after she was weaned from cardiopulmonary bypass, which was successfully resolved by the ligation of the hemiazygos vein. Postoperative enhanced computed tomography detected significant venovenous malformation from the hemiazygos vein to the left renal vein...

In cardiogenic shock patients with Interagency Registry for Mechanical Circulatory Support (INTERMACS) level 1, the need for temporary circulatory support is a predictor and modifier of patient outcome. Because this group includes patients with and without cardiopulmonary resuscitation (CPR) and is thus very heterogeneous, we investigated whether a further subclassification is useful. We compared 30-day and 1-year mortality of patients who underwent left ventricular assist device implantation after extracorporeal CPR with the aid of an extracorporeal life support system (CPR+ group; n = 40) with cardiogenic shock patients in which the extracorporeal life support system was implanted under non-CPR conditions (CPR- group, n = 68)...

OBJECTIVES: Haemolysis during left ventricular assist device support is associated with thrombosis. In this retrospective study, we analysed whether low-level haemolysis (LLH) as defined by simultaneously elevated lactate dehydrogenase (LDH) and free haemoglobin (fHb) levels had an impact on thromboembolic and bleeding events and on von Willebrand factor levels in HeartMate II patients. METHODS: After exclusion of patients with LDH >700 U/l and fHb >40 mg/dl at hospital discharge, 79 HeartMate II patients were included...

OBJECTIVES: Paediatric coronary artery bypass grafting is indicated in cases of clinically significant and symptomatic coronary stenosis, with frequent complications occurring in the perioperative period. To reduce complications and improve outcomes of these procedures, surgical microscopes have been used at our centre with the anastomosis performed by a microvascular surgeon. The purpose of this article is to report our institutional experience in all patients who have undergone paediatric coronary artery bypass grafting procedures with and without microvascular techniques...

We present a very rare case of isolated right pulmonary veins atresia in a 4-year-old girl. As the presence of a pulsatile blind pulmonary venous confluence adjacent to the left atrium was demonstrated by preoperative right pulmonary arterial wedge angiography, we applied sutureless pericardial marsupialization for the repair of right pulmonary veins atresia. She is currently 8 years old without pulmonary veins stenosis.

OBJECTIVES: Our goal was to investigate the outcome of the left atrioventricular valve (LAVV) after repair of atrioventricular septal defects (AVSDs) by analysing the mechanisms of LAVV failure. METHODS: A retrospective investigation of 202 children with AVSD, operated on between 1992 and 2016, was performed. Analysis focused on freedom from reoperation for LAVV dysfunction, with specific attention to the modes of failure. RESULTS: The population consisted of 129 (64%) patients with complete AVSD (cAVSD) and 73 (36%) patients with partial AVSD (pAVSD), corrected at a median age of 3...

OBJECTIVES: Surgical correction of commissural mitral valve prolapse can be challenging. Several surgical techniques, including commissural closure, leaflet resection with sliding plasty and chordal replacement, remain commonly in use. Conversely, papillary muscle head repositioning remains uncommonly utilized for the treatment of commissural prolapse. METHODS: Between January 2003 and December 2015, 518 patients underwent primary mitral valve repair for severe degenerative mitral valve regurgitation at our institution...

Scimitar syndrome is a rare congenital cardiac malformation defined as an anomalous pulmonary venous return from the right lung to the inferior vena cava. In adult patients, the surgical strategy chosen is very important because of concomitant diseases and conditions. Herein, we present a case in which a minimally invasive approach was successful for treating a combination of the adult form of the scimitar syndrome and severe degenerative mitral regurgitation.

It is currently unknown whether levosimendan can improve clinical outcomes in patients undergoing cardiac surgery. This meta-analysis aimed to assess the effect of levosimendan on mortality and the duration of intensive care unit (ICU) and hospital stay in adult patients undergoing cardiac surgery. A comprehensive search for eligible articles was conducted in PubMed, OVID and Cochrane databases of clinical trials and the Web of Science from database inception to August 2017. Stata/SE 11.0 was used to calculate the pooled odds ratio for postoperative mortality and the pooled standardized mean difference (SMD) for the duration of ICU stay and hospital stay...

Cavernostomy and fenestration were performed in a patient who developed a lung abscess and empyema in the left lung, which was damaged after multimodality therapy for advanced thymoma. The hospitalized patient suddenly experienced cardiopulmonary arrest due to major bleeding from the left main pulmonary artery. We immediately performed the main pulmonary arterial embolization, and the patient was resuscitated. Subsequently, the patient underwent supercharged free omental flap plombage performed in the following manner: first, laparoscopic harvesting of the omentum was performed in the supine position...

OBJECTIVES: The treatment of thoraco-abdominal aortic aneurysm continues to have a high mortality and paraplegia rate. In superaging societies, the methods of performing less invasive operations remain a major issue. We reviewed our 10-year experience in the treatment of thoraco-abdominal aortic aneurysm using a hybrid procedure of combined visceral reconstruction and thoracic endovascular aortic repair. METHODS: Sixty patients underwent a hybrid repair for the treatment of the thoraco-abdominal aortic aneurysm between 2007 and 2016...
