We investigated left ventricular (LV) function after surgical pulmonary valve replacement (sPVR) in patients with repaired Tetralogy of Fallot (rTOF) by Speckle Tracking Echocardiography (STE).Methods: 58 volunteers participated in this study who divided into 3 groups including 22 PVR patients (mean age 18.96±7 year), 16 repaired Tetralogy of Fallot and 20 healthy age match control. For all patients, we performed 2D echocardiography and STE.Results: 2D echocardiography in all groups showed normal LV ejection fraction without a significant statistical difference (64% sPVR, 60% in repaired Tetralogy of Fallot and 62.5% in the control group). However, the mean global longitudinal strains (GLS) of LV were significantly reduced in both sPVR (-17.5±2.5%) and repaired Tetralogy of Fallot (-17.1±4.7%) patients rather than control group (-20.2±0.7%) (P = 0.003). But GLS had no statistically significant difference between repaired Tetralogy of Fallot and sPVR patients (P=0.9). Segmental analysis of longitudinal strain (LS) showed a significant decrease in sPVR patients and repaired Tetralogy of Fallot group in basal anterior, basal septal, basal anterolateral segments, mid-anterior and anterolateral segments. Except for lower LS in the apical-anteroseptal segment, this level was mostly spared in both sPVR and repaired Tetralogy of Fallot patients.Conclusion: LVEF was within normal range after sPVR patients, but the pattern of impaired segmental LS and GLS did not change as compared with rTOF. Surgical PVR in patients with repaired TOF may not have a significant effect on the improvement of LV function assessed by STE. LV damage which happens during surgical correction of TOF may have a permanent deteriorating effect on LV function.","PeriodicalId":43653,"journal":{"name":"International Cardiovascular Research Journal","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2020-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44827835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Intra-Aortic Balloon Pump (IABP), as a mechanical support, is lifesaving in many cases of low cardiac output state. IABP is needed to be in place from a few hours to a few days. Weaning is usually done according to patients’ hemodynamic response. Up to now, many studies have addressed the withdrawal methods, but few are related to predict the support time. Objectives: This study aimed to evaluate whether high serum lactate levels are early predictors of IABP dependency after CABG surgery. Patients and Methods: This prospective cohort study was performed on 843 patients who underwent CABG surgery from April 2009 to January 2014 in Pars hospital. Among these patients, 47 ones required IABP support and were all entered into our study. Arterial blood samples were collected by 2-hour intervals during the first 12 hours after the operation. Serum lactate levels were compared according to IABP dependency. The data were analyzed using chi-square, t-test, and correlation coefficient and α = 0.05 was considered to be the significance level. Results: Based on the results, 97.8% of the patients (n = 46) were successfully weaned from IABP support and 95.7% (n = 45) survived to discharge from the hospital. Two patients with persistent serum lactate levels > 15 mmol/L in the first 12 hours of IABP support had the worst prognosis. A significant association was found between the mean serum lactate levels ≥ 6 mmol/L in the first 12 hours after the surgery and ≥ 48 hours dependency on IABP (P = 0.030). Conclusions: Prediction of IABP dependency may be possible by measuring serum lactate levels in the first 12 hours after CABG surgery.","PeriodicalId":43653,"journal":{"name":"International Cardiovascular Research Journal","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2016-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68174052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objectives: This study aimed to investigate the incidence of no-reflow phenomenon and its clinical, para-clinical, and angiographic determinants in patients who underwent primary PCI for ST Elevation Myocardial Infarction (STEMI). Patients and Methods: This non-randomized prospective cohort study was conducted on 397 patients in a cardiovascular tertiary care center in Tehran, Iran from April 2012 to April 2014. The inclusion criteria of the study were presenting with acute STEMI of ≤ 12 h duration or having admitted between 12 and 24 hours after onset with symptoms and signs of ongoing ischemia. The participants underwent standard coronary angiography. No-reflow phenomenon was defined as a Thrombolysis In Myocardial Infarction (TIMI) flow ≤ 2 and no presence of spasm, distal embolization, or dissection after completion of the procedure. The association between no-reflow and its determinants was assessed by chi-square, student’s t-test, or Mann–Whitney U test. Logistic regression models were also used for multivariate analysis. P values < 0.05 were considered to be statistically significant. Results: The participants’ mean (SD) age was of 59 (12.2) years and female/male ratio was 83/314. The incidence of no-reflow phenomenon was 63 (15.9%). Besides, the results of multivariate analysis showed that only thrombus burden, lesion length, time to reperfusion, and type of occlusion had an adjusted association with this phenomenon.

Objectives : This study aimed to compare the incidence of MACCE between the patients who underwent PCI or CABG due to significant Left Anterior Descending (LAD) stenosis with and without other coronary arteries involvement. Patients and Methods : This randomized mixed cohort study was conducted on 400 patients with Coronary Artery Disease (CAD), 200 with proximal LAD stenosis and 200 with non-proximal LAD stenosis, selected through census. Half of each group underwent PCI and the rest underwent CABG. The participants were followed at fixed intervals after the procedure and the incidence of MACCE was documented in their checklists. Then, relative risk index was used to compare the two groups regarding the incidence of MACCE.

Results : The study participants included 281 males and 119 females with the mean age of 61.36 ± 10.66 years.
