Antepartum fetal surveillance is the cornerstone of management in pregnancy. [1] It is done primarily to reduce the incidence of adverse fetal outcomes. It minimizes morbidity by optimizing the timing of delivery. Fetus at risk of chronic hypoxia is identified and unnecessary interventions are avoided. However, fetal surveillance acts as a diagnostic modality to detect the influence of maternal, placental, and fetal factors on the fetus. The timely detection of morbid changes in the fetal status followed by adequate interventions to avoid death or disability is one of the most important objectives of prenatal care. [2] Tests now commonly done for antepartum fetal surveillance are nonstress test (NST), amniotic fluid index (AFI), biophysical profile, Doppler study of umbilical artery (UA), and middle cerebral artery (MCA).[3 6] However, AFI and UA Doppler velocimetry both form an essential part of the antenatal surveillance in the assessment of fetal well being. UA Doppler is a powerful tool that allows the obstetrician to follow a sequence of fetal hemodynamic events that happen in response to placental insufficiency. [7] However, several studies have reported higher sensitivities and specificities for UA Doppler ratio for prediction of fetal prognosis. [3 6] Amniotic fluid is the product of complex and dynamic fetal and placental physiologic processes. Disruption of the fine balance may result in overproduction or underproduction of fluid. Liquor adequacy often reflects the fetal status. Oligohydramnios is associated with increased perinatal loss. Furthermore, other studies indicate that UA velocimetry is a predictor of adverse outcomes in pregnancies complicated by oligohydramnios. [8,9] Thus, arterial Doppler velocimetry measurement may be useful in predicting adverse pregnancy outcomes adjunct to other antenatal surveillance tests, especially the AFI. Therefore, the present study will be done to evaluate the comparative assessment of UA ratio and AFI in predicting adverse perinatal outcomes.
The goal of this observational study is to evaluate the clinical characteristics of patients undergoing permanent cardiac pacing and to compare procedural efficacy and safety of different implantation approaches in the clinical practice of the participating centres. The contribution of non-fluoroscopic anatomical and electrophysiological reconstruction systems to device implantation procedures will also be evaluated. Participants [patients over 18 years old with an indication to receive a definitive pacemaker/intracardiac defibrillator implant] will receive a permanent cardiac pacing implant as requested according to European Society of Cardiology (ESC) guidelines; the investigators will evaluate procedural efficacy and safety of different implantation approaches.
The purpose of the current study is to verify the effectiveness of the artificial intelligence algorithm applied to the electrocardiogram as a potential screening tool for left ventricular systolic dysfunction.
The goal of this observational study is to learn about the value of multimodal ultrasound in early detection of left ventricular systolic dysfunction in patients with chronic kidney disease(CKD). The main questions it aims to answer are: 1. If first-phase ejection fraction（EF1）could early detect the left ventricular systolic dysfunction in patients with CKD. 2. Whether EF1 can detect left ventricular systolic dysfunction in patients with CKD more sensitively than speckle-tracking echocardiography and myocardial work. Participants will need to cooperate to do an echocardiography. Researchers will compare healthy volunteers and patients with CKD to see if EF1 could early detect the left ventricular systolic dysfunction.
Modified TAPSE (m-TAPSE) is a new method in which TAPSE is measured by taking the difference between the apical and lateral tricuspid annulus distance during diastole and systole. It can be measured using transesophageal echocardiography (TEE) in the mid-esophageal four-chamber (ME 4CH) view and is an alternative easily measurable parameter for intraoperative assessment of RV systolic function as long as optimal imaging quality is achieved. In this prospective observational study, between 01.02.2024 and 01.01.2025, patients between the ages of 1-18 will undergo transcatheterization procedures using TTE and TEE under anesthesia by a pediatric cardiologist. TAPSE of these patients will be measured by TTE and TEE. TAPSE of the patients will be evaluated with TTE and TOE.
This study sought to evaluate the association of right ventricular systolic dysfunction and 28-day in-hospital mortality in patients with sepsis and septic shock. Prospective cohort study of adult patients admitted at Burapha university hospital from October 1, 2022 through June 30, 2023 for sepsis and septic shock, who had an echocardiogram within 72 hours after admission for evaluating right ventricular systolic function. Right ventricular systolic dysfunction was defned by the American Society of Echocardiography criteria. Outcomes included 28-day in-hospital mortality, maximal blood lactate, length of intensive care unit(ICU) stay and duration of mechanical ventilation.
The goal of this clinical trial is to learn about the effect of type 1 diabetes mellitus on cardiac functions and evaluate the correlation of the dysfunction with the tumor necrosis factor-α (TNF-α) an inflammation-related factor. The study population will be the patients with the diagnosis of type 1 diabetes mellitus and the healthy children es the control group. The main question[s] it aims to answer are: - Is diabetes affecting the systolic and diastolic cardiac functions - Is diabetes affecting the left and the right ventricles equally? - Does diabetes status, as assessed by HbA1c, have an impact on the occurrence of cardiac dysfunction? - Is TNF-α can be a marker for early diagnosis of cardiac dysfunction? Diabetic patients will be examined by both a pediatric endocrinologist and a pediatric cardiologist. Transthoracic echocardiography will be performed and TNF-α will be evaluated for both the diabetic patients and the healthy children.
The aim of our study is to try to establish a relationship between preoperative fasting-related volume changes and tricuspid annular plane systolic excursion (TAPSE), and to determine whether there are changes in right ventricular functions due to preoperative fasting.
A multicenter, randomized, double-blind, placebo-controlled phase III clinical trial to evaluate the effect of recombinant human Neuregulin-1 for injection on cardiac function and reverse ventricular remodeling in male patients with NT-proBNP ≤ 1700 pg/ml and female patients with NT-proBNP ≤ 4000 pg/ml and New York Heart Association class II-III chronic systolic heart failure, and to confirm its efficacy and safety.
