Post-infarction ventricular septal defect (VSD) is a rare but potentially lethal complication of acute myocardial infarction. Medical management is usually futile, so definitive surgery remains the treatment of choice but the risk surgery is very high and the optimal timing for surgery is still under debate. A 55-year-old man with no previous medical history attended the emergency-room for 12 h evolution of oppressive chest pain and strong anginal pain 7 days ago. On physical examination, blood pressure was 96/70 mmHg, pansystolic murmur over left sternal border without pulmonary crackles...

OBJECTIVES: To compare regional cerebral cortical blood flow (CBF) in infants born very preterm at term-equivalent age (TEA) and healthy newborns born full term and to examine the impact of clinical risk factors on CBF in the cohort born preterm. STUDY DESIGN: This prospective, cross-sectional study included infants born very preterm (gestational age at birth <32 weeks; birth weight <1500 g) and healthy infants born full term. Using noninvasive 3T arterial spin labeling magnetic resonance imaging, we quantified regional CBF in the cerebral cortex: sensorimotor/auditory/visual cortex, superior medial/dorsolateral prefrontal cortex, anterior cingulate cortex (ACC)/posterior cingulate cortex, insula, and lateral posterior parietal cortex, as well as in the brainstem, and deep gray matter...

BACKGROUND: Exercise training is an effective and low-cost tool for COPD rehabilitation. Thus, validating a non-exhaustive method to determine a patient's anaerobic threshold would be a very interesting tool in practical settings. We aimed to test the reproducibility of critical velocity values determined in a non-exhaustive manner (CVNE) and tolerance for exercise performed at this physiological marker in subjects with COPD. METHODS: Twelve subjects with COPD were evaluated in this cross-sectional study...

BACKGROUND: Conventional echocardiographic parameters, such as rest ejection fraction, perform poorly regarding the prediction of exercise tolerance in heart failure. The aim of the present study was to evaluate the contribution of hemodynamic instability in the observed lower functional capacity, investigating the role of left ventricular strain for the prediction of stress test duration in obese hypertensive patients with reduced ejection fraction. METHODS: Sixty-one patients with reduced ejection fraction underwent treadmill exercise echocardiography...

Major surgeries can result in high rates of adverse postoperative events. Reliable prediction of which patient might be at risk for such events may help guide peri- and postoperative care. We show how archiving and mining of intraoperative hemodynamic data in orthotopic liver transplantation (OLT) can aid in the prediction of postoperative 180-day mortality and acute renal failure (ARF), improving upon predictions that rely on preoperative information only. From 101 patient records, we extracted 15 preoperative features from clinical records and 41 features from intraoperative hemodynamic signals...

BACKGROUND: The current international guideline recommended 200 mg per day of hydrocortisone intravenously to treat septic shock. However, a subsequent study on cortisol metabolism actually showed an increase in cortisol level during sepsis. Hence, the smaller hydrocortisone dose of 100 mg per day might be sufficient and reduce steroid-associated complications. We aimed to compare the clinical outcomes of minimized hydrocortisone dose of 100 mg to the currently recommended dose in the treatment of septic shock patients...

Carbon monoxide (CO) and nitrogen oxide (NO) affect vasodilation and cause hemodynamic change. Hemodynamic instability due to liver transplantation may result in poor prognosis of graft. This study investigated the hemodynamic implications of CO and NO levels measured using carboxyhemoglobin (COHb) and methemoglobin (MetHb) during living donor liver transplantation (LDLT). The hemodynamic instability with a pressor dose (norepinephrine equivalent) was estimated 1 hour after graft reperfusion. COHb and MetHb were used as indexes of CO and NO, and were measured using an arterial blood gas analyzer...

INTRODUCTION: Pelvic fracture in trauma patients can lead to hemodynamic instability. External fixation is a treatment capable of stabilizing these injuries in the context of damage control surgery. Supra-acetabular pin offers the greater biomechanical stability but requires the use of intraoperative fluoroscopy. The aim of this study was to analyze our results for an ultrasound-guided supra-acetabular pinning. MATERIAL AND METHODS: Cross-sectional study with cadaveric specimens...

T-cell engaging therapies such as blinatumomab and anti-CD19 chimeric antigen receptor (CAR) T cells have revolutionized our approach to patients with relapsed and refractory acute lymphoblastic leukemia (ALL). However, the immune activation responsible for high remission rates is also responsible for the unique treatment-related toxicity of cytokine release syndrome (CRS). The clinical signs of CRS include fever, hemodynamic instability, and capillary leak, which correlate with T-cell activation and elevated cytokine levels...

BACKGROUND: Early recognition and timely intervention are critical steps for the successful management of shock. The objective of this study was to develop a model to predict requirement for hemodynamic intervention in the pediatric intensive care unit (PICU); thus, clinicians can direct their care to patients likely to benefit from interventions to prevent further deterioration. METHODS: The model proposed in this study was trained on a retrospective cohort of all patients admitted to a tertiary PICU at a single center in the United States, and validated on another retrospective cohort of all patients admitted to the PICU at a single center in the United Kingdom...

PURPOSE: The use of transesophageal echocardiography (TEE) has evolved to include patients undergoing high-risk non-cardiac procedures and patients with significant cardiac disease undergoing non-cardiac surgery. Implementation of basic TEE education in training programs has increased across a broad spectrum of procedures in the perioperative arena. This paper describes the use of perioperative TEE in non-cardiac surgery and provides an overview of the basic TEE examination. PRINCIPAL FINDINGS: Perioperative TEE is used to monitor hemodynamic parameters in non-cardiac procedures where there is a high risk of hemodynamic instability...

Acid-base alterations in patients with kidney failure and on hemodialysis (HD) treatment contribute to (1) intradialytic hypercapnia and hypoxia, (2) hemodynamic instability and cardiac arrhythmia, (3) systemic inflammation, and (4) a number of associated electrolyte alterations including potentiating effects of hypokalemia, hypocalcemia and, chronically, soft-tissue and vascular calcification, imparting poor prognosis and mortality. This paper discusses acid-base regulation and pathogenesis of dysregulation in patients with kidney failure...

RATIONALE: The increasingly intraoperative use of indocyanine green (ICG) means that it is necessary to be aware of both its advantages and potential adverse effects. PATIENT CONCERNS: A 76-year-old woman developed symptoms of sudden severe hemodynamic instability while undergoing coronary artery bypass grafting with ICG injection to detect the patency of the graft. The main clinical manifestations were a sudden drop in blood pressure and increased heart rate. DIAGNOSES: Severe side effects or allergic reaction of ICG...

Preoperative evaluation of incidentalomas for pheochromocytoma is imperative. This case report describes a scheduled adrenalectomy in an asymptomatic patient with what was eventually determined to be an incomplete biochemical workup. The intraoperative course was complicated by labile and rapid increases in blood pressure and heart rate, suggesting the missed diagnosis of pheochromocytoma. It is important for anesthesiologists to ensure adequate preoperative biochemical workup before excluding the possibility of coexisting pheochromocytoma...

Neurogenic shock, a distributive type of circulatory shock following spinal cord injury (SCI), results in profound hypotension. The consequent hemodynamic instability complicates clinical management, delays surgical intervention, and impacts neurological outcome. Moreover, the reported incidence of this condition varies significantly. Here, we establish the true incidence of neurogenic shock by comparing the most common clinical definitions used to diagnose the condition. Further, we characterize the acute progression and recovery of neurogenic shock...

Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE-mediated food allergy that usually presents in infancy. Cow's milk, soy, and grains are the most common food triggers. FPIES can present as a medical emergency with symptoms including delayed persistent emesis or diarrhea that can lead to severe dehydration and hemodynamic instability with abnormal laboratory markers. Diagnosis can often be made based on clinical history and noted improvement in symptoms once the suspected triggers have been removed from the diet, with oral food challenge as the gold standard for confirmation of diagnosis in unclear cases...
