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: 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...

BACKGROUND: Interventions in patients with a left ventricular assist device (LVAD) in the intensive care unit (ICU) are typically performed based on the results of conventional monitoring, such as vital signs and Swan-Ganz catheter (SGC) and LVAD parameters. These variables might not always accurately reflect a patient's cardiac function, volume status, and interventricular septal configuration, however. To assess the accuracy of standard monitoring, we performed routine continuous hemodynamic transesophageal echocardiography (hTEE) to evaluate cardiac function, volume status, and septal position...

Hemodynamic monitoring is essential for prompt and effective interventions in intensive care unit patients. We developed a custom-made transthoracic echocardiography transducer holder consisting of transducer holder and skin patch attachment. This holder allowed continuous transthoracic echocardiography monitoring in 5 adult patients with circulatory failure due to shock, and 6 pediatric patients after successful percutaneous closure of a ventricular septal defect. One case of an unexpected hemopericardium was promptly diagnosed and pericardiocentesis was performed, and 1 patient required extracorporeal membrane oxygenation support...

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...

The temporary total artificial heart (TAH-t) has been valuable as a bridge to transplantation in patients with biventricular failure. However, the challenges of accurately assessing pulmonary vascular resistance after TAH-t implantation can preclude these patients from heart transplantation, especially those with pre-existing pulmonary hypertension. The CardioMEMS Heart Failure System (St. Jude's Medical, Little Canada, MN) comprises a wireless pressure sensor that is implanted percutaneously in the pulmonary artery and transmits real-time measurements of pulmonary artery pressures...

Importance: Pulmonary hypertension (PH) is diagnosed by a mean pulmonary arterial pressure (mPAP) value of at least 25 mm Hg during right heart catheterization (RHC). While several studies have demonstrated increased mortality in patients with mPAP less than that threshold, little is known about the natural history of borderline PH. Objective: To test the hypothesis that patients with borderline PH have decreased survival compared with patients with lower mPAP and frequently develop overt PH and to identify clinical correlates of borderline PH...

INTRODUCTION: Cardiovascular diseases, and primarily coronary heart disease (CHD), are the leading cause of mortality in the developing countries, including Ukraine. Prognosis for patients with CHD depends mainly on progression of coronary atherosclerosis (ASVD). Molecular mechanisms of atherogenesis are studied in detail in order to find new targets of pharmacological intervention. THE AIM: to study the effect of resveratrol on parameters of central hemodynamics and myocardial ischemia in patients with stable coronary heart disease (CHD)...
