Current solutions for the monitoring of pulmonary artery pressure (PAP) in patients suffering from pulmonary hypertension are limited to invasive means. Non-invasive alternatives, such as Doppler echocardiography, are incompatible with continuous monitoring due to their dependency on qualified personnel to perform the measurements. In the present study, a novel non-invasive and unsupervised approach based on the use of electrical impedance tomography (EIT) is presented. The approach was evaluated in three healthy subjects undergoing hypoxia-induced variations in PAP...

Electrical cardiometry (EC) is a non-invasive and inexpensive method for hemodynamic assessment and monitoring. However, its feasibility for widespread clinical use, especially for the obese population, has yet to be determined. In this study, we evaluated the agreement and reliability of EC compared to transthoracic Doppler echocardiography (TTE) in normal, overweight, and obese children and adolescents. We measured stroke volume (SV) and cardiac output (CO) of 131 participants using EC and TTE simultaneously...

PURPOSE: Pulmonary hypertension (PH) diagnosis requires invasive assessment by right heart catheterization (RHC), but screening and monitoring are performed using non-invasive methods: echocardiography and cardiopulmonary exercise testing (CPET). The aim of the study was to assess correlations between the parameters obtained in non-invasive testing and RHC in patients with PH of different etiologies. MATERIAL/METHODS: The study included 53 medical records of PH patients (32 women) aged 29-81 years...

Zhongheng Zhang
Echocardiography is an invaluable tool in the management of patients with extracorporeal cardiopulmonary resuscitation (ECPR) and subsequent extracorporeal membrane oxygenation (ECMO) support and weaning. At the very beginning, echocardiography can identify the etiology of cardiac arrest, such as massive pulmonary embolism and cardiac tamponade. Eliminating these culprits saves life and may avoid the initiation of extracorporeal cardiopulmonary resuscitation. If the underlying causes are not identified or intrinsic to the heart (e...

BACKGROUND: Hemorrhagic shock and pneumonectomy causes an acute increase in pulmonary vascular resistance (PVR). The increase in PVR and right ventricular (RV) afterload leads to acute RV failure, thus reducing left ventricular (LV) preload and output. Inhaled nitric oxide (iNO) lowers PVR by relaxing pulmonary arterial smooth muscle without remarkable systemic vascular effects. We hypothesized that with hemorrhagic shock and pneumonectomy, iNO can be used to decrease PVR and mitigate right heart failure...

BACKGROUND: Perfusion index (PI) is a noninvasive measure of perfusion. ΔPI (difference between pre and post-ductal PI) may identify hemodynamically significant PDA. However, studies are limited to brief and intermittent ΔPI sampling. Our objective is to assess the value of continuous high resolution ΔPI monitoring in the diagnosis of PDA. METHODS: Continuous ΔPI monitoring in preterm infants was prospectively performed using two high resolution pulse oximeters...

Conjugation of Doxorubicin (DOX) to N-(2-Hydroxypropyl) methylacrylamide copolymer (HPMA) has significantly reduced the DOX-associated cardiotoxicity. However, the reports on the impact of HPMA-DOX conjugates on the cardiovascular system such as blood pressure (BP) and heart rate (HR) were in restrained animals using tail cuff and/or other methods that lacked the resolution and sensitivity. Herein, we employed radiotelemetric-spectral-echocardiography approach to further understand the in vivo cardiovascular hemodynamics and variability post administration of free DOX and HPMA-DOX...

OBJECTIVES: Focused transthoracic echocardiography (TTE) is used perioperatively for surgical patients. Intraoperative application of TTE is feasible, but its benefits remain unclear. The intention of this study was to investigate the effect of intraoperative TTE on the management of high-risk noncardiac surgery patients. DESIGN: A prospective interventional study. SETTING: Single-center university hospital. PARTICIPANTS: Fifty consecutive hemodynamically unstable high-risk patients anesthetized for noncardiac surgery...

A 78-year-old man was admitted to the authors' hospital with a short history of shortness of breath and pyrexia. He had long-standing moderate mitral regurgitation and stable coronary artery disease. Blood cultures grew Abiotrophia defectiva coccobaccili. Transesophageal echocardiography confirmed the diagnosis of mitral valve endocarditis that necessitated treatment with intravenous benzylpenicillin and gentamicin for six weeks. At nine days after admission the patient developed several episodes of self-limiting monomorphic ventricular tachycardia, without ischemic cardiac pain, associated with hemodynamic compromise requiring treatment with intravenous amiodarone and inotropic support in the Intensive Care Unit...

Transthoracic echocardiography (TTE) has become one of the most important diagnostic tools in the treatment of critically ill patients. It allows clinicians to recognise potentially reversible life-threatening situations and is also very effective in the monitoring of the fluid status of patients, slowly substituting invasive methods in the intensive care unit. Hemodynamic assessment is based on a few static and dynamic parameters. Dynamic parameters change during the respiratory cycle in mechanical ventilation and the level of this change directly corresponds to fluid responsiveness...

Transesophageal echocardiography (TEE) assessment after MitraClip implantation is limited by unequal orifices and jets, eccentric regurgitation, and the acute change of the annulus geometry. Periprocedural real-time invasive hemodynamic assessment of the mitral valve function requires experience in hemodynamic monitoring interpretation. However, it provides excellent accuracy as it does not take into account the changes of the mitral apparatus geometry and jet direction after MitraClip placement. While we seek to expand indications of Mitraclip to other patient subgroups, we should consider routine ancillary invasive hemodynamic assessment, in order to optimize our understanding, procedural results...

Aortic dissection is a life-threatening rare condition that may virtually present by any organ system dysfunction, the nervous system included. Acute cerebral infarction among multiple other neurological and non-neurological presentations is part of this acute aortic syndrome. Rapid and correct diagnosis is of extreme importance keeping in mind the possibility of thrombolytic treatment if a patient with a suspected ischemic stroke arrives to the Emergency Department within a 4.5-h window after symptom onset...

BACKGROUND: Cardiac tamponade is an emergency condition that requires early recognition and prompt pericardial decompression. Little has been reported on cardiac tamponade in liver retransplantation (reLT), but most cases are fatal. We managed a case of reLT complicated by accidental cardiac tamponade. CASE REPORT: A 59-year-old man underwent an emergency reLT because of liver cirrhosis with recurrent hepatitis B. During the dissection, suprahepatic exploration was attempted, but this resulted in severe hemorrhage because of the many tissue adhesions...

BACKGROUND: Left ventricular assist devices (LVADs) require serial assessment of right and left ventricular (RV & LV) volumes and function. Because the RV is not assisted, its function is a critical determinant of the hemodynamic and contributes significantly to postoperative morbidity and mortality. We evaluated the feasibility and the accuracy of tomographic-equilibrium radionuclide ventriculography (t-ERV) for the assessment of patients with LVADs. METHODS: Twenty-four patients with LVAD underwent t-ERV...

BACKGROUND AND OBJECTIVES: The aim of this retrospective study was to analyze differences in the initial hemodynamic assessment and its impact on the treatment in patients aged 80 years or older compared to younger patients during the first 6 h after admission to the medical intensive care unit (ICU). RESULTS: We analyzed 615 consecutive patients admitted to the medical ICU of which 124 (20%) were aged 80 years or more. The older group had a significantly higher acute physiology and chronic health evaluation (APACHE II) score, an overall mortality in the ICU and a presence of pre-existing cardiac disease...

BACKGROUND: Transition from an asymptomatic to symptomatic state in severe aortic stenosis is often difficult to assess. Identification of a morphological sign of increased hemodynamic load may be important in asymptomatic aortic stenosis to identify patients at risk. METHODS AND RESULTS: Thirty-nine patients with asymptomatic severe aortic stenosis (aortic valve area <1 cm(2), peak jet velocity >3.5 m/s) underwent exercise testing with simultaneous invasive hemodynamic monitoring and Doppler echocardiography...

Right ventricular (RV) failure after cardiac surgery is associated with an ominous prognosis. The etiology of RV failure is multifaceted and the ability to recognize RV failure early is paramount in order to initiate timely treatment. The present review focuses on different diagnostic modalities for RV function and discusses the normal versus abnormal findings in RV monitoring after cardiac surgery and the limitations of the applicable diagnostic modalities. There are specific challenges in RV assessment after cardiac surgery due to a loss of longitudinal contraction and a concomitant gain of transverse contraction...

Thoracic aortic aneurysms rupture and dissection are among the most devastating vascular diseases, being characterized by elevated mortality, despite improvements in diagnostic imaging and surgical techniques.An increased aortic root diameter (ARD) represents the main risk factor for thoracic aortic dissection and rupture and for aortic valve regurgitation.Even though arterial hypertension is commonly regarded as a predisposing condition for the development of thoracic aorta aneurysms, the role of blood pressure (BP) as determinant of aortic root enlargement is still controversial...
