Abstract Objectives To evaluate the correlation between left atrial dysfunction assessed by speckle tracking echocardiography and development of postoperative atrial fibrillation (POAF) in patients undergoing coronary artery bypass grafting. To determine the role of coronary risk factors in development of POAF. Method Patients undergoing CABG from January 2019 till June 2020 in Apollo institute, fulfilling the inclusion and exclusion criteria were included.Total of 200 patients were followed.They were subjected to LA strain and strain rate analysis by speckle tracking. Results The incidence of POAF in our study was 24% (n=48). The mean age of this study population was 59.13 years. The patients who developed POAF were older (68.5±9.048 vs 58.39±9.74 years, p value=0.05) than those with no POAF. POAF occurred in 2 phases. the highest proportion of POAF occurrence noticed on postoperative day 2. Among the total POAF cases 79.% occurred within the first 48 hours and 20.8% occurred later (p=0.001). Among the 48 patients who developed POAF, 5 of them developed recurrence during their hospital stay. They had reverted to sinus rhythm following anti-arrhythmic medication for a duration of >24 hours, but went on to develop recurrence of AF at a later. 4 among them reverted to sinus rhythm at discharge while 1 continued to remain in AF at discharge.The duration of hospital stay for patients with POAF group was 10.4 days compared with 10.04 days for those without POAF. Similarly the post-operative stay in the hospital was 7.4 days for the POAF group and 7.04 days for the NO POAF.There was no added economic impact secondary to AF.Comparing the values of left atrial volume index of both the groups it was derived that the mean LAVI value of the POAF group was 26.84+3.654 ml/m2 and that for the NO POAF group was 26.6+3.037ml/m2. Though the patients with POAF had larger LA volume, the chi square test analysis did not yield any clinically significant relationship between LAVI and POAF in our study (p=0.3). The mean LA global strain for the patients with POAF was 29.73+3.695%. And for the patients with no POAF was 36.3+4.854%. LA global strain was reduced in patients who developed POAF (P<0.001) which indicated a strong correlation between LA strain and POAF. Conclusion There is significant correlation between Global Left Atrial Strain and POAF in patients undergoing CABG (P<0.001).There is no significant correlation between patient factors like age, BMI, and the conventional coronary risk factors with POAFThere is no significant correlation between the conventional echocardiographic parameters like LA diameter, LAVI, LVDD, LVSD, LVEF and transmitral flow velocities with POAF. To conclude, preoperative speckle tracking assessment of LA has a strong predictive role in determining the occurrence of POAF in patients undergoing Coronary artery bypass grafting surgery.

Abstract Background Hereditary hemochromatosis (HH) is a very common genetic disease. Abnormally increased intestinal iron absorption and accelerated recycling of iron lead to progressive body iron accumulation and the generation of oxidative stress in tissues. In the late stages iron overload of the heart can lead to the left ventricular (LV) dysfunction. It is believed, that two dimensional speckle tracking echocardiography (2D STE) can evaluate LV dysfunction more accurately and earlier than conventional echocardiography. Evaluation of such assessment was the purpose of this paper. Methods We prospectively enrolled 58 patients with genetically confirmed HH; 29 healthy age- and sex-matched volunteers constituted the control group. Classic echocardiographic and 2D STE parameters (GE VIVID E9, EchoPAC v201) were compared between the groups, additionally correlations between echo and iron turnover parameters were performed. Results The HH patients had all standard echo parameters within the normal range. All 2D STE parameters were significantly worse in HH than in control group (Table 1). We did not find any correlation between echo and iron turnover parameters, whilst significant correlation with the time from diagnosis and the numbers of venesections was noticed. Conclusions Novel 2D STE analyzes seem to be helpful in early detection of heart abnormalities in HH patients. The correlations between the echo and iron indices are weak, allowing to suggest the lack of a "direct" relationship between the iron turnover and myocardial function and that myocardial iron overload is not the only mechanism involved in development of HH cardiomyopathy.

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.
