INTRODUCTION: Hemodynamic parameters measurements were widely conducted using pulmonary artery catheter (PAC) with thermodilution as a reference standard. Due to its technical difficulties in children, transthoracic echocardiography (TTE) has been widely employed instead. Nonetheless, TTE requires expertise and is time-consuming. Noninvasive cardiac output monitoring such as ultrasonic cardiac output monitor (USCOM) and electrical velocimetry (EV) can be performed rapidly with less expertise requirement...

OBJECTIVES: This study aims to establish parameters for identifying normal function for each of the 3 iterations of balloon-expandable valves and 2 iterations of self-expanding valves. BACKGROUND: Expected transthoracic echocardiographic Doppler-derived hemodynamic data for transcatheter aortic valves inform pre-implant decision-making and post-implanted monitoring of longitudinal valve function. METHODS: We collected the Echocardiography Core Lab measured mean gradients and effective orifice area (EOA) from discharge or 30-day echocardiograms from randomized trials; the PARTNER (Placement of Aortic Transcatheter Valves) trials for the balloon-expandable valves and the Medtronic CoreValve US Pivotal trial and Medtronic CoreValve Evolut R United States IDE Clinical Study for the self-expanding valves...

Background: Thrombosis is a complication of prosthetic valves on oral anticoagulants which is associated with significant morbidity and mortality. A re-operation carries a substantial risk, with mortality rate from 10% to 15% in selected series, which may be 2- or 3-folds higher in critically ill patients. This study conducted in a tertiary care cardiology unit aimed to evaluate the effectiveness and safety of thrombolytic therapy in stuck mitral bileaflet heart valves. Methods: As a prospective observational study, clinical symptoms and fluoroscopy were the mainstay in diagnosis of stuck mitral valve...

BACKGROUND: Preeclampsia is among the most common medical complications of pregnancy. The clinical utility of invasive hemodynamic monitoring in preeclampsia (e.g., Swan-Ganz catheter) is controversial. Thoracic impedance cardiography (TIC) and Doppler echocardiography are noninvasive techniques but they both have important limitations. NICaS™ (NI Medical, PetachTikva, Israel) is a noninvasive cardiac system for determining cardiac output (CO) that utilizes regional impedance cardiography (RIC) by noninvasively measuring the impedance signal in the periphery...

PURPOSE OF REVIEW: Hemodynamic investigations are required in patients with shock to identify the type of shock, to select the most appropriate treatments and to assess the patient's response to the selected therapy. We discuss how to select the most appropriate hemodynamic monitoring techniques in patients with shock as well as the future of hemodynamic monitoring. RECENT FINDINGS: Over the last decades, the hemodynamic monitoring techniques have evolved from intermittent toward continuous and real-time measurements and from invasive toward less-invasive approaches...

Hypertensive disorders of pregnancy are the second leading cause of maternal deaths worldwide. Superimposed preeclampsia is an increasingly common problem and often associated with impaired placental perfusion. Understanding the underlying mechanisms and developing treatment options are crucial. The pregnant stroke-prone spontaneously hypertensive rat has impaired uteroplacental blood flow and abnormal uterine artery remodeling. We used Ang II (angiotensin II) infusion in pregnant stroke-prone spontaneously hypertensive rats to mimic the increased cardiovascular stress associated with superimposed preeclampsia and examine the impact on the maternal cardiovascular system and fetal development...

While the pulmonary artery catheter (PAC) is still interesting in specific situations, there are many alternatives. A group of experts from different backgrounds discusses their respective interests and limitations of the various techniques and related measured variables. The goal of this review is to highlight the conditions in which the alternative devices will suffice and when they will not or when these alternative techniques can provide information not available with PAC. The panel concluded that it is useful to combine different techniques instead of relying on a single one and to adapt the "package" of interventions to the condition of the patient...

PURPOSE OF REVIEW: To review the different methods available for the assessment of cardiac output (CO) and describe their specific indications in intensive care and perioperative medicine. RECENT FINDINGS: In critically ill patients, persistent circulatory shock after initial resuscitation is an indication for the assessment of CO to monitor the response to fluids and vasoactive agents. In patients with circulatory shock associated with right ventricular dysfunction, pulmonary artery hypertension, or acute respiratory distress syndrome, invasive CO monitoring using indicator dilution methods is indicated...

PURPOSE OF REVIEW: The present review discusses the current role of the pulmonary artery catheter (PAC) in the hemodynamic monitoring of critically ill patients. RECENT FINDINGS: The PAC has an important role in the characterization and management of hemodynamic alterations in critically ill patients. Use of the PAC has decreased in the last 30 years because of recent advances in less invasive hemodynamic monitoring techniques, in particular transpulmonary thermodilution and echocardiography, combined with the publication of the results of several randomized trials that failed to show improvements in outcome with the use of the PAC in various settings...

BACKGROUND AND OBJECTIVE: Atrial fibrillation is the most common cardiac arrhythmia, which may occur during the perioperative period and lead to hemodynamic instability due to loss of atrial systolic function. During atrial fibrillation management, electrical cardioversion is one of the therapeutic options in the presence of hemodynamic instability; however, it exposes the patient to thromboembolic event risks. Transesophageal echocardiography is a diagnostic tool for thrombi in the left atrium and left atrial appendage with high sensitivity and specificity, allowing early and safe cardioversion...

BACKGROUND: Trastuzumab (TZ) therapy requires careful monitoring of left ventricular (LV) ejection fraction (LVEF) because it can be potentially cardiotoxic. However, LVEF is an imperfect parameter and there is a need to find other variables to predict cardiac dysfunction early. Left atrium (LA) enlargement has proven to be a powerful predictor of adverse outcomes in several disease entities. HYPOTHESIS: Baseline LA volume enlargement might predict TZ-related LV dysfunction...

OBJECTIVE: Blood flow across the mitral valve during early left ventricular (LV) filling produces a 3-dimensional rotational fluid body, known as a vortex ring, that enhances LV filling efficiency. Diastolic dysfunction is common in elderly patients, but the influence of advanced age on vortex formation is unknown. The authors tested the hypothesis that advanced age is associated with a reduction in LV filling efficiency quantified using vortex formation time (VFT) in octogenarians undergoing coronary artery bypass graft (CABG) surgery...

BACKGROUND: Hypertrophic cardiomyopathy (HCM) is a common inherited cardiac disease characterized by varying degrees of left ventricular outflow tract obstruction. In a large cohort, we compare the outcomes among 3 different hemodynamic groups. METHODS AND RESULTS: We prospectively enrolled patients fulfilling standard diagnostic criteria for HCM from January 2005 to June 2015. Detailed phenotypic characterization, including peak left ventricular outflow tract pressure gradients at rest and after provocation, was measured by echocardiography...

Hemodynamic monitoring is essential during the treatment of the critically ill in order to address the hemodynamic alterations and assess the response to treatment. Traditionally classified causes of shock and underlying pathophysiological mechanisms are often neglected by resuscitative strategies included in the guidelines. Most of hemodynamic management focuses on the ability to early recognise patients susceptible to increase cardiac output (CO) and mean arterial pressure (MAP) after a defined fluid challenge by eliciting Starling's law of the heart, and less is known of the ones presenting in shock and not volume responsive...

BACKGROUND AND AIM OF THE STUDY: Xenograft conduits have been used successfully to repair congenital heart defects, but are prone to failure over time. Hence, in order to improve patient outcomes, better xenografts are being developed. When evaluating a conduit's performance and safety it must first be compared against a clinically available control in a large animal model. The study aim was to evaluate a clinically available xenograft conduit used in right ventricular outflow tract (RVOT) reconstruction in a sheep model...
