SEVERE MITRAL REGURGITATION AFTER PMBV? COMPARISON BETWEEN INOUE AND MULTI-TRACK TECHNIQUES

Objectives: To compare the frequency of severe mitral regurgitation after percutaneous mitral balloon valvuloplasty (PMBV) via Inoue balloon and multi-track balloon technique in our population. Methodology: In this retrospective observational study which was conducted at a tertiary care cardiac center of Karachi, Pakistan between 2015 and 2020 on Hospital registry of PMBV patients. Data were categorized in to two groups, Inoue balloon or multi-track balloon technique. Post procedure echocardiographic and catheterization parameters and in-hospital outcomes and complications, including severe MR, were compared between two groups. Results: Out of 470 PMBV procedures, 286 (60.9%) were performed with multi-track and 184 (39.1%) with Inoue balloon. Improvement in mitral value area was significantly higher with multi-track as compared to Inoue balloon (0.66±0.31 cm2 vs. 0.56±0.29 cm2; p<0.001). Severe MR was not significant, 3.5% (10/286) vs. 4.3% (8/184); p=0.639 for multi-track and Inoue balloon. One patient in Inoue balloon group and two patients in multi-track group required emergency valve surgery. Stroke was observed in two patients of multi-track group and two patients from the same group developed tamponade. No in-hospital mortality was observed. Conclusion: Post-procedure severe MR is a significant and frequent complication. Rate of post procedure severe MR are similar for PMBV via Inoue balloon and multi-track balloon. Both methods are equally effective with equal success rate.

Aortic Root Dilatation in Children and Adolescents At Al-Hawary General Hospital, & National Benghazi Cardiac Center -Libya

Isolated dilatation of the aortic root and/or ascending aorta is a rare but well-known cardiovascular manifestation, can be caused by a variety of congenital or acquired conditions; that lead to the weakening of the aortic wall. The study aimed to detect the cause and the rate of the aortic root dilatation in children and adolescents, and to assess the effect of the Beta-adrenergic blockers in preventing further dilatation in the aortic root. A case series study was perform with five years of follow-up at Al-Hawary General Hospital, National Benghazi Cardiac Center. A total of 91 patients were seen with ascending aortic dilatation and/or root dilatation during the period from 6/2016 - 6/2021 included in the study diagnosed by clinical examination, chest x-ray, and echocardiogram. The diagnosis in 34/91(37%) was Tetralogy of fallout (TOF) and truncus arteriosus, 57/91 (63%) was dilated aortic root, 25/57 (44%) bicuspid aortic valve (BAV), 22/57 (38.5%) Marfan syndrome, 4/57(7%) Noonan syndrome, 2/57(3.5%) Turner syndrome, 3/57(5%) Ehlers-Danlos syndrome, 1/57(2%) idiopathic. Follow-up results of three months – five years: 57/91 patients with aortic root dilatation were followed up, none of the Marfan syndrome and Ehlers-Danlos syndrome patients who received beta-blockers had shown progression in the dilatation of the aortic root, and all patients who had bicuspid aortic valve did not show any progression in the dilatation without using medication. Conclusions: Dilated aortic root is a common finding in Marfan syndrome, bicuspid aortic root, and Ehlers-Danlos syndrome, and its progress could be decreased by using beta-adrenergic blockers in rapidly progressing dilation.

Nutritional status and associated factors among children with congenital heart disease in selected governmental hospitals and cardiac center,Addis Ababa Ethiopia

Background Children with congenital heart disease are at risk for poor growth and under-nutrition compared with healthy children. The aim of this study was to assess the nutritional status of children with congenital heart disease and associated factors in selected governmental hospitals and cardiac center Addis Ababa, Ethiopia. Method Institutional based cross sectional study among 373 children aged under15 years was conducted from February to March; 2021G.c. Data was collected using structured questionnaire and chart review. Z-scores based on WHO reference ranges were used. Anthropometric z-scores based on WHO 2007 reference ranges were generated for each child. Weight-for-age z-scores for children 0–10 years and height-for-age and BMI-for-age z-scores for all children. Binary logistic regression was used for associated factors. Result A total of 373 children were participated in this study. The prevalence of wasting and stunting was 144(38.6%) and 134(35.9%) respectively. The prevalence of underweight and malnutrition in children under 10 years was 143(43.1%). Most of the children were diagnosed with VSD (36.7%). Children age group of 13 months-5 years were associated with wasting and underweight [AOR = 0.434, 95%CI: (0.231, 0.816)] and [AOR = 0.360, 95%CI: (0.183, 0.711)] respectively. Children diagnosed with PAH were 1.885 times more likely to be underweight [AOR = 1.885, 95%CI: (1.094, 3.246)]. When the hemoglobin level increases by every unit per g/dl the chance to be wasting and underweight decreases by 13.1 and 18.6%[AOR = 0.869, 95%CI: (0.792, 0.955)] and [AOR = 0.869, 95%CI: (0.792, 0.955)] respectively. The level of SPO2 is associated with stunting and underweight [AOR = 0.970, 95%CI: (0.943, 0.998)] and [AOR = 0.970, 95%CI: (0.943, 0.998)] respectively. Conclusion The prevalence of malnutrition in children with CHD is pretty high. Decreased level of hemoglobin and SPO2 was found to be associated factors for malnutrition in this case. There need to be a new strategy about including different health professional while care giving.

Risk Stratification of Patients Undergoing Primary Pci for Stemi Using Dynamic Timi Risk Score at A Tertiary Care Cardiac Center

Objective: To determine the frequency of severity based on dynamic TIMI scoring among STEMI patients undergoing primary PCI at a tertiary care Cardiac center. Subject and Methods: This case series study was carried out on 171 patients admitted with acute STEMI undergoing PPCI at the department of cardiology NICVD, Karachi for six months from February 1st to July 30th, 2018. After the selection of patients, they were shifted to the Cath lab, the arterial sheath was passed through the femoral route only although the radial route is also present but to reduce the bias we choose the same femoral route only. Angiography was done and the area of occlusion identified was ballooned/stented by the interventional cardiologist having experience of at least 03 years. The study parameters of dynamic TIMI risk score points were recorded on a predesigned proforma. Results: The mean age of the patients of the study subjects was 59.89±12.67, Distribution of gender was stated, 133(77.78%) patients were male and (22.22%) were female. Outcome dynamic TIMI risk score severity was stated, 86(50.29%) patients had a low risk, 62(36.26%) patients had a moderate risk, 23(13.45%) patients had a high risk. Conclusion: When used in STEMI patients, this new approach shows the ever-changing risks and could be helpful in clinical decision-making as well as risk assessment.

Clinical and Microbiological Characteristics of Infective Endocarditis at a Cardiac Center in Saudi Arabia

Background Infective endocarditis (IE) is a serious disease with complex pathology and significant mortality. Little information is known regarding clinical and microbiological characteristics in Saudi Arabia. This study surveyed these characteristics at a Cardiac Center in Riyadh, Saudi Arabia over a period of 5 years. Methods This retrospective study was done on all infective endocarditis (IE) patients admitted to Prince Sultan Cardiac Center between January 1, 2015, and December 31, 2019. Clinical characteristics, microbiological results, management, and outcomes were assessed. Result A total of 340 cases of infective endocarditis were identified over the study period. Most patients (64%) were 50 years old or above, and 67% were males. Fever was the most common clinical presentation, and a murmur was audible in a fifth of patients. Blood cultures were positive in 177 (52%) cases. The most common organisms were Staphylococcus aureus, coagulase negative Staphylococcus and viridans group Streptococcus. Most common microbiological organisms causing native valve endocarditis were viridans group Streptococcus (32%) followed by methicillin-susceptible Staphylococcus aureus (21%), and for prosthetic valve endocarditis they were coagulase negative Staphylococcus (32%) followed by methicillin-susceptible Staphylococcus aureus (23%), the most common causes of culture negative endocarditis were Q-fever and brucellosis. Predisposing cardiac conditions were present in 127 (37%) patients, most commonly rheumatic heart disease and congenital heart disease. Surgical intervention was done in 26% of cases, with an overall in-hospital mortality rate of 6.76%. Conclusion We demonstrate the epidemiological, clinical, and microbiological profile of infective endocarditis in a tertiary care cardiac center in Saudi Arabia. It gives information concerning the prevalence of responsible organisms. This information will be helpful in assessing patients with suspected IE and in planning management of cases knowing the relative frequency of types of microorganisms encountered.

Hyperlactatemia and its adverse patient outcomes among patients who underwent cardiopulmonary bypass surgery at national cardiac centre Addis Ababa, Ethiopia 2021. Retrospective observational study

Background: Hyperlactatemia and lactic acidosis are commonly encountered during and after cardiac surgery. Hyperlactatemia is highly suggestive of tissue ischemia and is associated with a prolonged intensive care unit stay, a prolonged requirement for respiratory and cardiovascular support, and increased postoperative mortality. Objective: To assess hyperlactatemia and adverse outcomes among patients who underwent cardiopulmonary bypass surgery at Cardiac Center Ethiopia, Addis Ababa, Ethiopia, 2021.Method: An institution-based retrospective cross-sectional study was employed among all patients who underwent cardiopulmonary bypass surgery from December to January 2020. Blood lactate samples were collected intraoperatively and postoperatively. We entered the collected data into Epidata version 4.2 and export it to SPSS 25 for analysis. We did descriptive statistics for categorical and continuous variables and chi-square to show an association between the outcome variable and independent variables. We entered variables fitted in bivariate analysis into multivariable analysis to show the strength of the association and the statistically significant variable.Result: The prevalence of hyperlactatemia in this study among patients who underwent cardiac surgery procedures at Cardiac Center Ethiopia was 37.5 %. A rise in lactate level prolongs ICU stay, prolongs intubation duration, and increases the need for Inotropes support. Lactate level was measured on the immediate postoperative day within 10 hours after the surgery and was defined as lactate level > 3 mmol/L in the first hour after surgery. Age > 40 years [AOR: 6.8 (95% CI 1.7-25), P=<0.008]. female gender [AOR: 1.8 (95% CI 1.1-3.8), P=0.048]. Variables statistically significant were declared at 95 % CI, p-value < 0.05.Conclusion and Recommended: An early rise in lactate levels in patients who underwent cardiopulmonary bypass surgery is a strong and robust predictor of morbidity. As a result, screening of patients in the preoperative period and strict follow-up management of those factors is recommended.

OPERATIVE MORTALITY OF CORONARY ARTERY BYPASS GRAFTING IN PATIENTS WITH LOW SERUM ALBUMIN AFTER NUTRITIONAL SUPPORT

Objectives: The aim of this study was to determine the frequency of operative mortality in patients who had low serum albumin on admission and were undergoing coronary artery bypass grafting (CABG) after nutritional support at a tertiary care cardiac center in Karachi, Pakistan. Methodology: A retrospective study was conducted at an adult cardiac surgery department of the largest tertiary care cardiac center in Karachi, Pakistan. Patients who had undergone isolated CABG during January to December 2019 admitted with low serum albumin (less than 3.5mg/dl) and received nutritional treatment before surgery were included in the study. Patients were monitored for a month to measure the 30 day mortality. Results: There were 82.4% male patients and the mean age was 55.49±8.52 years. Preoperative mean serum haemoglobin, serum creatinine, and serum albumin levels were 12.225±1.19 mg/dl, 1.05±0.21 mg/dl, and 2.825±0.39 mg/dl respectively. Postoperative mortality was recorded in 1.7% of the total patients. Conclusion: In patients with low serum albumin levels and had undergone isolated CABG after nutritional pre-treatment, mortality was mainly associated with peri-operative myocardial infarction. While, the incidence of delayed wound healing and atrial fibrillation were found to be high in these patients.
