BACKGROUND: Acute decompensation with heart failure, angina or syncope may be the first indication of undiagnosed aortic stenosis, but should be uncommon when the disorder is known and managed by watchful waiting. There is a lack of information on the proportion of patients with acute decompensated aortic stenosis with and without a prior diagnosis and their outcomes. METHODS: We examined the records of patients with aortic stenosis (ICD code 135.0) admitted to three UK hospitals between January 2015 and January 2016...

: Paravalvular leak (PVL) is an uncommon but serious complication associated with the implantation of prosthetic valves. Following aortic valve replacement, up to 5% of patients affected by PVL develop clinical symptoms of heart failure, hemolysis or both. Percutaneous treatment of PVL has emerged instead of conventional surgery, as a well tolerated and less invasive procedure but remains a challenge. We present the case of a young woman with mechanical aortic and mitral prostheses, who presented surgical aortic PVL caused by a serious frailty of native annulus, became symptomatic after 5 months and was successfully percutaneously treated with an Amplatzer Duct Occluder device...

Ventricular pseudoaneurysm is an uncommon, potentially fatal complication that has been associated with myocardial infarction, cardiac surgery, chest trauma, and infectious processes. Diagnosis can be challenging, as cases are rare and slowly progressing and typically lack identifiable features on clinical presentation. As a result, advanced imaging techniques have become the hallmark of identification. Ahead, we describe a patient who presents with acute decompensated heart failure and was incidentally discovered to have a large right ventricular pseudoaneurysm that developed following previous traumatic anterior rib fracture...

OBJECTIVES: Early mortality following hip fracture surgery is high and pre-operative risk assessment for the individual patient is challenging. A risk model could identify patients in need of more intensive perioperative care, provide insight in the prognosis and allow for risk-adjustment in audits. This study aimed to develop and validate a risk prediction model for 30-day mortality following hip fracture surgery: the Hip fracture Estimator of Mortality Amsterdam (HEMA). METHODS: Data on 1050 consecutive patients undergoing hip fracture surgery between 2004 and 2010 were retrospectively collected and randomly split into a development cohort (746 patients) and validation cohort (304 patients)...

Quadruple-valve repair or replacement is associated with significant morbidity and mortality because the clinical situation of severe disease of all 4 valves implies incipient myocardial damage. We report a case of redo quadruple-valve repair in a patient with rheumatic heart disease who had undergone the Ross procedure 14 years earlier. He presented with heart failure. Cardiac evaluation revealed severe disease of all 4 valves, necessitating surgery. Because he was in advanced heart failure and all 4 valves were suitable for repair, a quadruple-valve repair was performed...

BACKGROUND: Tuberculous pericarditis can impair the heart's function and cause death; long term, it can cause the membrane to fibrose and constrict causing heart failure. In addition to antituberculous chemotherapy, treatments include corticosteroids, drainage, and surgery. OBJECTIVES: To assess the effects of treatments for tuberculous pericarditis. SEARCH METHODS: We searched the Cochrane Infectious Diseases Group Specialized Register (27 March 2017); the Cochrane Central Register of Controlled Trials (CENTRAL), published in the Cochrane Library (2017, Issue 2); MEDLINE (1966 to 27 March 2017); Embase (1974 to 27 March 2017); and LILACS (1982 to 27 March 2017)...

: The risk for postoperative venous thromboembolism (VTE) is increased in patients aged more than 70 years and in elderly patients presenting with co-morbidities, for example cardiovascular disorders, malignancy or renal insufficiency. Therefore, risk stratification, correction of modifiable risks and sustained perioperative thromboprophylaxis are essential in this patient population. Timing and dosing of pharmacoprophylaxis may be adopted from the non-aged population. Direct oral anti-coagulants are effective and well tolerated in the elderly; statins may not replace pharmacological thromboprophylaxis...

The management of heart failure patients presenting in a moribund state remains challenging, despite significant advances in the field of ventricular assist systems. Bridge to decision involves using temporary devices to stabilize the hemodynamic state of such patients while further assessment is performed and a decision can be made regarding patient management. We developed a new temporary left ventricular assist system employing a disposable centrifugal pump with a hydrodynamically levitated bearing. We used three adult goats (body weight, 58-68 kg) to investigate the 30-day performance and hemocompatibility of the newly developed left ventricular assist system, which included the pump, inflow and outflow cannulas, the extracorporeal circuit, and connectors...

Personalized management of cardiovascular disorders (CVDs), also referred to as personalized or precision cardiology in accordance with general principles of personalized medicine, is the selection of best treatment for an individual patient. It involves the integration of various 'omics' technologies such as genomics and proteomics as well as other new technologies such as nanobiotechnology. Molecular diagnostics and biomarkers are important for linking diagnosis with therapy and monitoring of therapy. Because CVDs involve perturbations of large complex biological networks, a systems biology approach to CVD risk stratification may be used for improving risk-estimating algorithms and modeling of personalized benefit-of-treatment may be helpful for guiding choice of intervention...

BACKGROUND: Among patients undergoing non-cardiac surgery, major vascular surgery is associated with a high risk of perioperative myocardial infarction (MI). Currently there are no perioperative MI risk calculators accounting for intraoperative and postoperative risk factors in vascular surgery patients. We aimed to investigate specific risk factors for perioperative MI after major open vascular surgery to determine which patients are at highest risk of MI, and the association of perioperative MI with perioperative transfusion...

BACKGROUND: Recently, it was reported that angiopoietin-like protein 2 (ANGPTL2) secreted from a pathologically stressed heart accelerates cardiac dysfunction in an autocrine/paracrine manner, and that suppression of ANGPTL2 production in the heart restored cardiac function and myocardial energy metabolism, thereby blocking heart failure (HF) development. Interestingly, circulating ANGPTL2 concentrations reportedly increase in HF patients, suggesting a possible endocrine effect on cardiac dysfunction...

BACKGROUND: Despite recent innovations in cataract surgery, pupillary diameter is one of the most important affecting factors in outcome of this surgery. As cataract surgery is performed ideally when the pupil is sufficiently dilated, anesthesia may contribute significantly in success or failure of this operation. This study was performed to evaluate the effect of nitrous oxide on pupillary diameter in cataract surgery under general anesthesia. METHODS: Forty patients with cataract, scheduled for operation under general anesthesia, were randomly allocated into two groups...

OBJECTIVES: Due to its high prevalence and serious consequences it is very important to be well aware of factors that might be related to medical complications, mortality, hospital stay and functional recovery in elderly patients with hip fracture. MATERIAL AND METHODS: A prospective study of a group of 130 patients aged over 75 years admitted for osteoporotic hip fracture. Their medical records, physical and cognitive status prior to the fall, fracture type and surgical treatment, medical complications and functional and social evolution after hospitalization were evaluated...

BACKGROUND: The Left Ventricular Assist Device (LVAD) has revolutionised our treatment of advanced stage heart failure, giving debilitated patients a new lease on life. A small proportion of these LVAD patients can be bridged-to-recovery. The identification of these patients and decision to wean, however, can be challenging. METHODS: The need to fully explant the device upon recovery has evolved to a minimalist approach aiming to avoid injury to the 'recovered' heart...

BACKGROUND AND AIMS: There is uncertainty regarding the optimal management of endoscopically invisible ("flat") low grade dysplasia in ulcerative colitis. Such a finding does not currently provide an automatic indication for colectomy; however, a recommendation of surveillance instead of surgery is controversial. The aim of this study was to determine the clinical and cost-effectiveness of colonoscopic surveillance versus colectomy for endoscopically invisible low-grade dysplasia of the colon in ulcerative colitis...

Fetal Cardiology. Experiences from a tertiary referral centre in Stockholm, Sweden This review provides a brief overview of the current position and clinical experiences of fetal cardiology at a tertiary referral centre in Stockholm, Sweden. In Stockholm, more than 60% of congenital cardiac defects requiring surgery or catheter intervention before one year of age are detected before birth. This not only results in termination of pregnancy in the majority of cases carrying a poor prognosis, but also conveys a better postnatal care and prognosis in cases of continued pregnancy...
