BACKGROUND: For coronary interventions the arterial access via the radial artery is associated with fewer vascular access site complications, and has been shown to reduce major bleeding when compared to the femoral approach. But the endomyocardial biopsy (EMB) approach is usually done by a transfemoral or cervical access known to be associated with an increased risk of artery puncture and its potential complications (i.e., false aneurysm, artery-venous fistula) and needs post-procedural immobilization...

Targeted temperature management (TTM) improves survival and neurological outcome after nontraumatic cardiac arrest. However, TTM is not used widely after traumatic cardiac arrest because of concerns that it might exacerbate bleeding. We report the use of postarrest TTM after repair of blunt myocardial rupture. A 48-year-old man was admitted after being rescued from a major traffic accident by the local emergency service. Focused sonography showed pericardial fluid without cardiac tamponade. Computed tomography showed a large hematoma in the anterior mediastinum associated with hemopericardium...

INTRODUCTION: Studying the venous compartment may add valuable information on background mechanisms and (patho)physiology of the cardiovascular system in normal pregnancies and pregnancies complicated by preeclampsia. Every component of the venous pulse wave is reflecting a specific stage of the cardiac cycle in the right atrium, and can be recognized in the neck veins, the hepatic and the renal veins. Previous studies have demonstrated the repeatability and reproducibility of venous Doppler sonography and venous pulse transit time in renal interlobar and hepatic veins...

OBJECTIVES: A fetal persistent intrahepatic right umbilical vein has been linked to anomalies and genetic disorders but can be a normal variant. We conducted a retrospective review to determine other sonographic findings that can stratify fetuses for further evaluation. METHODS: A total of 313 fetuses had a persistent intrahepatic right umbilical vein identified on 17- to 24-week sonography. The outcome was any major congenital anomaly or an adverse neonatal outcome, which was defined as aneuploidy, fetal demise, or neonatal death...

Sonography and transthoracic echocardiography (TTE) are seldom used for assessment of metastatic tumor thrombi in the cardiovascular system in routine clinical practice. We performed this retrospective study to evaluate the combination of sonography with TTE for diagnosis of metastatic tumor thrombi in heart and systemic vessels. Vascular, abdominal, pelvic, and small-part sonography was applied in 18 patients, and TTE was conducted simultaneously in 14 patients. Tumor thrombi invaded into the inferior vena cava system in 12 patients, superior vena cava system in 5 patients, and aorta in 1 patient; they extended to the right cardiac chambers in 11 patients...

OBJECTIVES: Recent studies conclude that cardiac surgery patients are prone to both mortality and morbidity in the weeks after discharge. Complications such as pleural and pericardial effusions may influence physical recovery due to symptoms such as dyspnoea, chest pain and fatigue. Dedicated follow-up and timely treatment of postoperative complications are suggested. METHODS: A randomized, controlled intervention trial including 76 patients, in the ratio of 1 : 1...

Goldenhar syndrome is a rare congenital disease associated with hemifacial hypoplasia as well as ear and ocular defects. Sometimes it is also associated with vertebral and other bone defects, cardiac malformations and central nervous system anomalies. Its aetiology is not yet clarified in the literature. We present a case of multiple malformations detected in the morphology ultrasound (at 22 weeks of gestation), namely absent nasal bones, micrognathia and absent left radius, among other defects. Genetic counselling, fetal brain MRI and cardiac sonography, which showed ventricular septal defect, were performed...

Focused cardiac sonography and targeted neonatal echocardiography refer to goal-directed cardiac imaging using ultrasound, typically by noncardiologic specialists. Although the former consists of a rapid qualitative assessment of cardiac function, which is usually performed by acute care practitioners, the latter refers to detailed functional echocardiography to obtain quantitative and qualitative indexes of pulmonary and systemic hemodynamics in sick neonates and is typically performed by neonatologists. Although the use of these modalities is increasing, they still remain unavailable in most North American centers providing acute care to neonates, partly because of limited data regarding their direct impact on patient care...

INTRODUCTION: Point of care ultrasound (PoCUS) has become an established tool in the initial management of patients with undifferentiated hypotension. Current established protocols (RUSH and ACES) were developed by expert user opinion, rather than objective, prospective data. PoCUS also provides invaluable information during resuscitation efforts in cardiac arrest by determining presence/absence of cardiac activity and identifying reversible causes such as pericardial tamponade. There is no agreed guideline on how to safely and effectively incorporate PoCUS into the advanced cardiac life support (ACLS) algorithm...

The effective performance of fetal cardiac examination using spatiotemporal image correlation (STIC) technology requires 2 essential steps: volume acquisition and postprocessing. An important prerequisite is training sonologists to acquire high-quality volume data sets so that when analyzed, such volumes are informative. This article is part 2 of a series on 4-dimensional sonography with STIC. Part 1 focused on STIC technology and its features, the importance of operator training/experience and acquisition of high-quality STIC volumes, factors that affect STIC volume acquisition rates, and general recommendations on performing 4D sonography with STIC...

The influence of cardiac activity on the viscoelastic properties of intracranial tissue is one of the mechanisms through which brain-heart interactions take place, and is implicated in cerebrovascular disease. Cerebrovascular disease risk is not fully explained by current risk factors, including arterial compliance. Cerebrovascular compliance is currently estimated indirectly through Doppler sonography and magnetic resonance imaging (MRI) measures of blood velocity changes. In order to meet the need for novel cerebrovascular disease risk factors, we aimed to design and validate an MRI indicator of cerebrovascular compliance based on direct endogenous measures of blood volume changes...

BACKGROUND: According to previous studies, even after embryonic cardiac activity is detected, the pregnancy loss rate remains 3-4 %. The objectives of this study were to investigate the differences in ultrasound parameters between a miscarriage group and an ongoing pregnancy group during the 1(st) trimester and to build a logistic model to predict early pregnancy loss (EPL) after the appearance of embryonic cardiac activity in patients who have undergone in vitro fertilization embryo transfer (IVF-ET) treatment...

Enhanced measures for resuscitation of adults are based on basic measures of resuscitation. The central elements are highly effective chest compressions and avoidance of disruptions that are associated with poor patient outcomes that occur within seconds. The universal algorithm distinguishes the therapy for ventricular fibrillation from the therapy in asystole or pulseless electrical activity (PEA) by the need of defibrillation, and amiodarone administration in the former. Defibrillation is biphasic. In all other aspects, there are no differences in therapy...

If myocardial infarction remains silent, only clinical signs of complications may unveil its presence. Life-threatening complications include myocardial rupture, thrombus formation, or arterial embolization. In the presented case, a 76-year-old patient was admitted with left-sided hemiparesis. In duplex sonography, a critical stenosis of the right internal carotid artery was identified and initially but retrospectively incorrectly judged as the potential cause for ischemia. During operative thromboendarterectomy, arterial embolism of the right leg occurred coincidentally, more likely pointing towards a cardioembolic origin...
