BACKGROUND: It is unknown whether contrast transcranial color-coded sonography of vertebral artery monitoring via the foramen magnum window (cTCCS-VA) is useful to detect right-to-left shunt (RLS). We investigated whether cTCCS-VA can be proposed as an alternative to middle cerebral artery monitoring via the temporal bone window (cTCCS-MCA) for RLS detection, as compared with contrast transesophageal echocardiography (cTEE). METHODS: We evaluated 112 patients with ischemic stroke or transient ischemic attack...

BACKGROUND: Transesophageal echocardiography (TEE) is a valuable monitor for patients undergoing cardiac and noncardiac surgery as it allows for evaluation of cardiovascular compromise in the perioperative period. It is challenging for anesthesiology residents and medical students to learn to use and interpret TEE in the clinical environment. A critical component of learning to use and interpret TEE is a strong grasp of normal cardiovascular ultrasound anatomy. METHODS: Fifteen fourth-year medical students and 15 post-graduate year (PGY) 1 and 2 anesthesiology residents without prior training in cardiac anesthesia or TEE viewed normal cardiovascular anatomy TEE video clips; participants were randomized to learning cardiac anatomy in generative retrieval (GR) and standard practice (SP) groups...

Improvements in clinical management of the preterm infant have reduced the rates of the two most common forms of brain injury, such as severe intraventricular hemorrhage and white matter injury, both of which are contributory factors in the development of cerebral palsy. Nonetheless, they remain a persistent challenge and are associated with a significant increase in the risk of adverse neurodevelopment outcomes. Repeated episodes of ischemia-reperfusion represent a common pathway for both forms of injury, arising from discordance between systemic blood flow and the innate regulation of cerebral blood flow in the germinal matrix and periventricular white matter...

Background: Our previous study showed sub-epicardial longitudinal strain (EpiLS) was an independent prognostic factor for worse outcome in regular treated hypertension but not global longitudinal strain (GLS) and sub-endocardial longitudinal strain (EndLS). Increased blood pressure variability (BPV) has been found associated with target organ damage in hypertension. However, effects of BPV on layer-specific longitudinal strain have not been well studied. Purpose: The aim of this study was to investigate the effects of different blood pressure parameters on layer-specific longitudinal strain in hypertension...

Background.: The presence of patent foramen ovale (PFO) has been linked to many illness, including cryptogenic stroke, transient ischemic attack, migraine, platypnea-orthodeoxia syndrome and decompression sickness in scuba divers. Transesophageal echocardiography is the gold standard technique for the visualization of atrial septal anatomy, but it is a secondary level exam, not always available, with additional associated costs and not completely free from procedural risks. Standard transthoracic echocardiography (TTE) has a too low sensitivity for PFO screening...

BACKGROUND: Microsurgical resection of vestibular schwannomas is demanding, even if not all of these tumors represent a challenge for experienced surgeons. In order to make the right decisions when it comes to balancing the extent of tumor resection with preservation of function, the surgeon must possess detailed knowledge of the surgical techniques and also have mastered these. OBJECTIVE: The current article describes the state-of-the-art of the three major microsurgical techniques for resection of vestibular schwannomas, their pearls and their perils...

BACKGROUND: The aim of this paper was to establish a minimally invasive method for deriving the left ventricular time varying elastance (TVE) curve beat-by-beat, the monitoring of which's inter-beat evolution could add significant new data and insight to improve diagnosis and treatment. The method developed uses the clinically available inputs of aortic pressure, heart rate and baseline end-systolic volume (via echocardiography) to determine the outputs of left ventricular pressure, volume and dead space volume, and thus the TVE curve...

Despite the high prevalence of the patients with heart failure with preserved ejection fraction (HFpEF), our knowledge about this entity, from diagnostic tools to therapeutic approach, is still not well established. The evaluation of patients with HFpEF is mainly based on echocardiography, as the most widely accepted tool in cardiac imaging. Identification of left ventricular (LV) diastolic dysfunction has long been considered as the only responsible for HFpEF, and its evaluation is still "sine qua non" of HFpEF diagnostics...

Stress echocardiography is a widely available, safe, low-cost, versatile imaging modality which is becoming increasingly recognized as a valuable tool in the assessment of patients with native and prosthetic left-sided valvular heart disease. It provides a quantitative assessment to help guide clinical decision-making when discordance exists between symptoms and severity of valve disease. Exercise (treadmill or bicycle) remains the preferred stress modality, but pharmacological augmentation with dobutamine can be used if needed...

BACKGROUND AND OBJECTIVES: In clinical trials, hypertensive patients tend to have higher interleukin-18 (IL-18) concentrations than normotensive groups, but the relationship between IL-18 and left ventricular hypertrophy (LVH), which is a marker of end-organ damage, is not well studied. We aimed to investigate the relationship between IL-18 and LVH in apparently healthy subjects free of clinically significant atherosclerotic disease. SUBJECTS AND METHODS: We enrolled 198 subjects (102 women and 96 men) between May 2006 and March 2007, who were free of cardiovascular or immune diseases, but were suspected to have hypertension...
