MEASUREMENT OF CARDIAC OUTPUT WITH THE ESOPHAGEAL DOPPLER CARDIAC FUNCTION MONITOR DURING LIVER TRANSPLANTATION

Background:There are wide number of diseases of almost every system in the body which can affect heart in a number of different ways including increasing demands on the heart ,ventricular dysfunction ,rhythm abnormalities ,valve abnormalities ,pulmonary pressures and lot more.Cardiac involvement in systemic diseases is usually silent or oligosymptomatic and includes different pathophysiological mechanisms such as myocardial inflammation, infarction ,subendocardial vasculitis,valvular disease and different patterns of fibrosis. Objective : To study association between systemic illnesses (hematological, endocrinal , renal) and cardiac function abnormalities as ventricular function,cardiac dimensions ,pulmonary artery pressure and pericardial effusion,for early diagnosis and treatment to decrease morbidity and mortality in patient with systemic illness. Design/Method:It was a cross sectional,descriptive study The present study was conducted in the Department of Pediatrics, LLRM Medical College,Meerut,Uttar Pradesh over a period of 1 year (June 2019-June 2020) Results: Cardiac findings in all three groups show ECG abnormalities and echocardiographic changes compared to general population. ECG abnormalities were prolonged PR interval and sinus tachycardia while echocardiographic changes mainly left ventricular(LV) dilatation and hypertrophy ,increased cardiac output ,ventricular dysfunction and pulmonary arterial hypertension(PAH),were noted in a significant proportion of patients. Conclusion:Systemic illnesses affect cardiac parameters in various ways including prolonged PR interval,cardiac dilatation,chamber hypertrophy ,high cardiac output,high cardiac index ,PAH and ventricular dysfunction.

AbstractBackgroundObjective markers of cardiac function are limited in the outpatient setting and may be beneficial for monitoring patients with chronic cardiac conditions.ObjectiveWe assess the accuracy of a scale, with the ability to capture ballistocardiography, electrocardiography, and impedance plethysmography signals from a patient’s feet while standing on the scale, in measuring stroke volume and cardiac output compared to the gold-standard direct Fick method.MethodsThirty-two patients with unexplained dyspnea undergoing level 3 invasive cardiopulmonary exercise test at a tertiary medical center were included in the final analysis. We obtained scale and direct Fick measurements of stroke volume and cardiac output before and immediately after invasive cardiopulmonary exercise test.ResultsStroke volume and cardiac output from a cardiac scale and the direct Fick method correlated with r = 0.81 and r = 0.85, respectively (P < 0.001 each). The mean absolute error of the scale estimated stroke volume was -1.58 mL, with a 95% limits of agreement (LOA) of -21.97 mL to 18.81 mL. The mean error for the scale estimated cardiac output was -0.31 L/min, with a 95% LOA of -2.62 L/min to 2.00 L/min. The change in stroke volume and cardiac output before and after exercise were 78.9% and 96.7% concordant, respectively between the two measuring methods.ConclusionsThis novel scale with cardiac monitoring abilities may allow for non-invasive, longitudinal measures of cardiac function. Using the widely accepted form factor of a bathroom scale, this method of monitoring can be easily integrated into a patient’s lifestyle.

Abstract Funding Acknowledgements This study was supported by the grant of CJ healthcare 2016 research fund. Background Liver cirrhosis (LC) has been known to affect cardiovascular performance. Limited study have evaluated the alteration of myocardial function in patients with LC after liver transplantation (LT). Purpose The aim of study was to evaluate changes of cardiac function in patients with cirrhosis following LT using conventional and speckle-tracking echocardiography and late gadolinium enhancement (LGE) of cardiac magnetic resonance (MR). Methods Thirty-five patients with cirrhosis (mean age, 57.1 ± 9.0; male, 75%) who were listed for LT were prospectively enrolled. Patients underwent conventional, speckle-tracking echocardiography, and cardiac MR imaging with LGE. Echocardiography and cardiac MR were performed at pre and 1 year after LT. Cirrhotic patients were compared with normal control (n = 20, mean age, 65.0 ± 14.8; men, 11(55%)) and echocardiographic and cardiac MR data were compared pre and post LT. Results Conventional and speckle-tracking echocardiography and Cardiac MR imaging demonstrated hyperdynamic left ventricular (LV) function in patients with cirrhosis (LV ejection fraction (EF) with cardiac MR 67.8 ± 7.0% in LC vs. 63.4 ± 6.4% in control, P = 0.028; global longitudinal strain (GLS) -24.3 ± 2.6% in LC vs. -18.6 ± 2.2% in control, P < 0.001). There were no LGE in patients with cirrhosis and no significant differences in LV size, LV wall thickness, LV mass index, and diastolic function between cirrhotic patients and control group (all P > 0.1). Corrected QT interval (QTc) in electrocardiogram was prolonged in LC patients (P < 0.001). One-year after LT, LV end-diastolic diameter and LV end-diastolic volume significantly decreased (P = 0.016 and 0.022, respectively). Although LVEF showed no significant changes 1 year post-LT (P = 0.362), LV-GLS (from -24.7 ± 1.8% to -20.8 ± 3.4%, P < 0.001) significantly decreased. QTc interval also decreased 1 year after LT (from 470.4 ± 29.6msec to 428.2 ± 31.6msec, P = 0.001). Conclusions The present study demonstrated that cirrhotic patients showed hyperdynamic circulation and prolonged QTc interval compared with normal controls. After 1 year LT, LV size reduced and augmented LV function was normalized. Given that no LGE in cardiac MR and normalized GLS and QTc after LT, cardiac dysfunction in LC patients could be reversed by LT.
