BACKGROUND: Current guidelines support the use of dobutamine stress echocardiography (DSE) prior to non-cardiac surgery in higher risk patients who are unable to perform at least 4 metabolic equivalents of physical activity. We evaluated post-operative outcomes of patients in different operative risk categories after pre-operative DSE. METHODS: We collected data from the medical record on 4,494 patients from January 1, 2006 to December 31, 2011 who had DSE up to 90 days prior to a non-cardiac surgery...

Pseudoaneurysm is one of the complications after arterial cannulation. We report the case of a patient with ST-segment elevation myocardial infarction due to aortic pseudoaneurysm after surgical mitralvalvuloplasty. Careful evaluation should be performed in cases of ST-segment elevation myocardial infarction following cardiac surgery, even after several months.

Variability refers to differences in physiological function between individuals, which may translate into different disease susceptibility and treatment efficacy. Experiments in human cardiomyocytes face wide variability and restricted tissue access; under these conditions computational models are a useful complementary tool. We conducted a computational and experimental investigation in cardiomyocytes isolated from samples of the right atrial appendage of patients undergoing cardiac surgery to evaluate the impact of variability in action potentials (APs) and sub-cellular ionic densities on calcium transient dynamics...

Proton-pump inhibitors (PPI) as pantoprazole are highly effective acid suppressive agents that belong to the world's most sold medication. However, they are pronounced to have immunosuppressive aspects. In our study, a negative influence of PPI on functions of polymorphonuclear cells in vitro like phagocytosis, oxidative burst, chemotaxis, and killing activity was shown, whereas formation of neutrophil extracellular traps (NET)osis remained unaffected. Pantoprazole stimulation additionally reduced the production of the proinflammatory cytokine IL-1β in whole blood assay as well as the production of IL-2 and IFN-γ after whole blood stimulation with phytohaemagglutinin...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) has evolved as effective treatment in patients with symptomatic severe aortic stenosis (AS) and increased operative risk. Data on the influence of previous sternotomy on the risk of TAVI are limited. AIM: We sought to investigate the impact of previous cardiac surgery with sternotomy on clinical outcomes and quality of life (QoL) after TAVI. METHODS: A total of 148 consecutive patients with symptomatic, severe AS who underwent TAVI were included...

A 69-year-old man came to our emergency department with nausea, vomiting and upper abdominal pain under the suspicion of an ileus. Four weeks before he had had an elective aortic valve replacement. The basal thoracic slides of the abdominal CT-scan revealed a significant amount of pericardial effusion, after which the patient was referred for emergency cardiac surgery. Abdominal complaints are rarely the primary symptoms of severe heart failure.

Anaemia is common before cardiac surgery and is associated with increased morbidity and mortality. The World Health Organization (WHO) definition of anaemia is lower for women than for men by 10 g.l-1 , potentially putting women at a disadvantage compared with men with regard to pre-operative optimisation. Our hypothesis was that women with borderline anaemia (defined by us as haemoglobin concentration 120-129 g.l-1 ) would have a higher rate of red cell transfusion, morbidity and mortality than non-anaemic women (haemoglobin ≥ 130 g...

Caseous calcification of the mitral annulus (CCMA) is considered a rare variant of mitral annular calcification (MAC) due to caseous transformation of the inner material and prevalence of CCMA, about 0.63% of all MAC cases and 0.06%-0.07% of the population. The precise pathophysiology of CCMA is still unknown. It is a chronic degenerative disorder common in the elderly, particularly in women. Caseous calcification of the mitral annulus (CCMA) is a soft peri-annular extensive calcification, resembling cardiac tumors, abscesses, vegetation, or calcified thrombus, which is composed of an admixture of calcium, fatty acids, and cholesterol with a toothpaste-like texture...

The development of an aorto-right ventricular fistula is a rare complication of cardiac surgery. The most common treatment is surgical closure of the fistula, but percutaneous closure of the fistula has become an attractive alternative option. We present a case of successful utilization of live/real time three/four-dimensional transoesophageal echocardiography (3/4DTEE) to select the correct device size for percutaneous closure of an adult patient presenting with an aorto-right ventricular (AO-RV) fistula following aortic valve replacement...

OBJECTIVES: Controversy remains regarding the use of deep hypothermic circulatory arrest (DHCA) in neonatal cardiac surgery. Alterations in cerebral mitochondrial bioenergetics are thought to contribute to ischaemia-reperfusion injury in DHCA. The purpose of this study was to compare cerebral mitochondrial bioenergetics for DHCA with deep hypothermic continuous perfusion using a neonatal swine model. METHODS: Twenty-four piglets (mean weight 3.8 kg) were placed on cardiopulmonary bypass (CPB): 10 underwent 40-min DHCA, following cooling to 18°C, 10 underwent 40 min DHCA and 10 remained at deep hypothermia for 40 min; animals were subsequently rewarmed to normothermia...

The purpose of this study is to evaluate the efficacy and safety of novel oral anticoagulant (NOAC) versus warfarin therapy in patients undergoing different operations. We performed a systematic review of MEDLINE, EMBASE, Cochrane Controlled Trials Register, and reports presented at scientific meetings. The efficacy and safety of NOACs during the perioperative period was compared to that using warfarin. Of the 2652 studies initially reviewed, we identified 9 that included 15,880 patients for the meta-analysis...

Objective: Female sex is a known risk factor for cardiac surgery, and tricuspid valve (TV) disease is more common in women. There are few data on sex-stratified surgical outcomes for isolated TV surgery. An administrative database was used to compare acute in-hospital outcomes between men and women undergoing isolated TV surgery. Methods: Patients aged >18 who underwent TV repair or replacement from 2004 to 2013 were identified using the National Inpatient Sample...

Background: The right ventricle (RV) is not designed to sustain high pressure leading to failure. There are no current medications to help RV contraction, so further information is required on adaption of the RV to such hypertension. Methods: The Right Ventricle in Children (RVENCH) study assessed infants with congenital heart disease undergoing cardiac surgery with hypertensive RV. Clinical and echocardiographic data were recorded, and samples of RV were taken from matched infants, analysed for proteomics and compared between pathologies and with clinical and echocardiographic outcome data...

Background: Acute kidney injury (AKI) is a frequent complication of cardiac surgery. We sought prognostic combinations of postoperative biomarkers measured within 6 h of surgery, potentially in combination with cardiopulmonary bypass time (to account for the degree of insult to the kidney). We used data from a large cohort of patients and adapted methods for developing biomarker combinations to account for the multicenter design of the study. Methods: The primary endpoint was sustained mild AKI, defined as an increase of 50% or more in serum creatinine over preoperative levels lasting at least 2 days during the hospital stay...
