J Cardiothorac Vasc Anesth 2024; 38:974-981. [PMID: 38326195 DOI: 10.1053/j.jvca.2023.12.037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2023] [Revised: 12/24/2023] [Accepted: 12/27/2023] [Indexed: 02/09/2024]
Abstract
OBJECTIVE The aim of this study was to evaluate the efficacy of ultrasound-guided multiple injection costotransverse block (MICB) and compare it with erector spinae plane block (ESPB) for poststernotomy pain relief in pediatric cardiac surgical patients. DESIGN A prospective, randomized, double-blind, comparative study. SETTING At a single institution tertiary referral cardiac center. PARTICIPANTS A total of 90 children with acyanotic congenital heart disease requiring surgery via sternotomy. INTERVENTIONS Children were allocated randomly to 1 of the 3 following groups: ESPB (group 1), MICB (group 2), or Control (group 3). Participants in groups 1 and 2 received 4 mg/kg of 0.2% ropivacaine for bilateral ultrasound-guided block after induction of anesthesia. Postoperatively, intravenous paracetamol was used for multimodal analgesia, and fentanyl/tramadol was used for rescue analgesia. MEASUREMENTS AND MAIN RESULTS The modified objective pain score (MOPS) was evaluated at 0, 1, 2, 4, 6, 8, 10, and 12 hours postextubation. After all exclusions, 84 patients were analyzed. The MOPS score was found to be significantly lower in ESPB and MICB groups compared to the control group until 10 hours postextubation (p < 0.05), with no statistically significant difference at the 12th hour (p = 0.2198). The total intraoperative fentanyl consumption (p = 0.0005), need for fentanyl supplementation on incision (p < 0.0001), and need for rescue opioid requirement in the postoperative period (p = 0.034) were significantly lower in both the ESPB and MICB groups than the control group. There were no statistically significant differences in both primary and secondary outcomes between the ESPB and MICB groups. CONCLUSION Ultrasound-guided MICB was effective and comparable to ESPB for post-sternotomy pain management in pediatric cardiac surgical patients.

Successful balloon dilatation of an infolded polytetrafluoroethylene graft: An unusual cause of early Fontan failure. Ann Pediatr Cardiol 2023; 16:77-78. [PMID: 37287847 PMCID: PMC10243666 DOI: 10.4103/apc.apc_85_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/16/2022] [Revised: 09/12/2022] [Accepted: 09/12/2022] [Indexed: 06/09/2023] Open
Abstract
Despite optimal medical management, an 8-year-old boy had persistent pleural drainage following total cavopulmonary connection. Detailed evaluation, including computed tomography angiography, confirmed obstruction at the lower end of the circuit due to infolding of the polytetrafluoroethylene graft. Balloon dilation of the obstruction resulted in prompt resolution of pleural effusion with sustained relief at 1-year follow-up. The case demonstrates the importance of careful assessment in the diagnosis and successful nonsurgical management of an unusual cause of obstruction in the Fontan circuit.

Abstract
Background: In this prospective randomized controlled trial, we compared the standard del Nido cardioplegia solution (SDN) with the modified del Nido cardioplegia solution (MDN) in which the base solution was the plain Ringer solution. Methods: A total of 80 patients aged < 12 years undergoing intracardiac repair of Tetralogy of Fallot were randomized into SDN (n = 39) or MDN (n = 41) groups. The primary outcome was a change in cardiac index (CI). Secondary outcomes were ventricular arrhythmias after the release of aortic-cross clamp, postoperative inotropic score (IS), time to peripheral rewarming, duration of mechanical ventilation, intensive care unit (ICU) length of stay, and hospital length of stay, and electron microscopic differences between the 2 groups. Cardiac Troponin-I, inflammatory markers tumor necrosis factor-α (TNF-α), and interleukin-L (IL-6) were measured. Results: Applying the noninferiority confidence interval approach, the difference between the changes in CI between the 2 groups was -0.093 L/min/m2 (95% CI: -0.46-0.27 L/min/m2) which was within the noninferiority threshold of -0.5 indicating that CI was similar in both SDN and MDN. Ventricular arrhythmias postclamp release (P = .91), IS (P = .09), duration of mechanical ventilation (P = .27), ICU length of stay (P = .50), hospital length of stay (P = .57), IL-6 (P = .19), TNF-α (P = .17), Troponin-I (P = .15), electron microscopy changes (P > .05) were not different between groups. Conclusion: MDN was shown to be noninferior to the SDN cardioplegia in terms of preservation of cardiac index. In addition, other metrics indicative of myocardial protection were similar between groups. In developing nations where SDN is not available or is expensive, MDN cardioplegia is an acceptable alternative.

Abstract
An isolated carotid artery is a rare aortic arch anomaly. Instead of connecting to the aorta, the isolated carotid artery connects anomalously to the pulmonary artery. Chronically altered cerebral circulation poses the risk of cerebral hyperaemia following surgical reimplantation. We describe successful reimplantation of the isolated left common carotid artery in a child, highlighting the importance of a multidisciplinary approach for good clinical and neurological outcomes. We also briefly discuss the embryologic basis of this rare arch anomaly.

Abstract
BACKGROUND Neurodevelopmental abnormalities are common in congenital heart disease (CHD), more so in cyanotic CHDs. Perioperative factors have been known to affect neurodevelopmental outcomes. AIM We aimed to determine the neurodevelopmental outcomes following open-heart surgery in cyanotic CHD. METHODS In this prospective observational study, eligible infants and children ≤21 months with cyanotic CHD planned for open-heart surgery underwent preoperative neurodevelopmental assessment using Developmental Assessment Scale for Indian Infants (DASII) to look for any motor and/or mental delay. A second neurodevelopmental assessment was performed after 9 months ± 2 weeks of cardiac surgery. Follow-up DASII was conducted through interactive video conferencing in 23 of 60 patients due to COVID-19 pandemic. The univentricular and biventricular repair groups were compared in terms of their neurodevelopmental outcomes. Perioperative factors were compared between neurodevelopmental "delay" and "no delay" groups. RESULTS Of the 89 children enrolled, preoperative motor and mental delay were present in 29 and 24 children, respectively. Follow-up DASII could be performed in 60 children. At follow-up, motor delay was present in seven and mental delay in four children. Overall, there was a significant improvement in both motor and mental developmental quotient at follow-up. There was no significant difference in either motor or mental domains between univentricular and biventricular groups. Among the perioperative variables, only the postoperative length of stay in intensive care unit was significantly different between neurodevelopmental "delay" and "no delay" groups (P = 0.04). CONCLUSION Neurodevelopmental delay occurred substantially among unoperated children with cyanotic CHD. The neurodevelopmental status improved significantly following open-heart surgery among the survivors. Delay was associated with length of stay in intensive care following cardiac surgery.

Concomitant Transthyretin Amyloidosis and Severe Aortic Stenosis in Elderly Indian Population: A Pilot Study. JACC CardioOncol 2021; 3:565-576. [PMID: 34746852 PMCID: PMC8551518 DOI: 10.1016/j.jaccao.2021.08.008] [Citation(s) in RCA: 21] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2021] [Revised: 08/15/2021] [Accepted: 08/18/2021] [Indexed: 01/15/2023] Open
Abstract
BACKGROUND Prevalence of both degenerative severe aortic stenosis (AS) and transthyretin cardiac amyloidosis (ATTR-CA) increases with age. Dual disease (AS+myocardial ATTR-CA) occurs in significant proportion of patients undergoing surgical aortic valve replacement (SAVR). OBJECTIVES This study aimed to determine the prevalence of ATTR-CA in severe AS in the Indian population, identify noninvasive predictors of its diagnosis, and understand its impact on prognosis. METHODS Symptomatic severe AS patients aged ≥65 years undergoing SAVR were enrolled. ATTR-CA diagnosis was based on preoperative 99m-technetium pyrophosphate (PYP) scan and intraoperatively obtained basal interventricular septum biopsy for myocardial ATTR-CA, and excised native aortic valve for isolated valvular ATTR-CA. Primary amyloidosis was excluded by serum/urine protein electrophoresis with serum immunofixation. RESULTS SAVR was performed in 46 AS patients (age 70 ± 5 years, 70% men). PYP scan was performed for 32 patients, with significant PYP uptake in 3 (n = 3 of 32, 9.4%), suggestive of myocardial ATTR-CA. On histopathological examination, none of the interventricular septum biopsy specimens had amyloid deposits, whereas 33 (71.7%) native aortic valves showed amyloid deposits, of which 19 (57.6%) had transthyretin deposition suggestive of isolated valvular amyloidosis. Noninvasive markers of dual disease included low myocardial contraction fraction (median [interquartile range], 28.8% [23.8% to 39.1%] vs 15.3% [9.3% to 16.1%]; P = 0.006), deceleration time (215 [144 to 236] ms vs 88 [60 to 106] ms; P = 0.009) and global longitudinal strain (-18.7% [-21.1% to -16.9%] vs -14.2% [-17.0% to -9.7%]; P = 0.030). At 1-year follow-up, 2 patients died (4.3%); 1 each in myocardial ATTR-CA negative and positive groups (3.4% vs 33.3%; P = 0.477). CONCLUSIONS Dual disease is not uncommon in India. Isolated valvular amyloidosis in severe AS is much more common.

Abstract
OBJECTIVES We sought to clarify the variations in the anatomy of the superior cavoatrial junction and anomalously connected pulmonary veins in patients with superior sinus venosus defects using computed tomographic (CT) angiography. METHODS CT angiograms of 96 consecutive patients known to have superior sinus venosus defects were analysed. RESULTS The median age of the patients was 34.5 years. In seven (7%) patients, the defect showed significant caudal extension, having a supero-inferior dimension greater than 25 mm. All patients had anomalous connection of the right superior pulmonary vein. The right middle and right inferior pulmonary vein were also connected anomalously in 88 (92%) and 17 (18%) patients, respectively. Anomalous connection of the right inferior pulmonary vein was more common in those with significant caudal extension of the defect (57% vs 15%, p=0.005). Among anomalously connected pulmonary veins, the right superior, middle, and inferior pulmonary veins were committed to the left atrium in 6, 17, and 11 patients, respectively. The superior caval vein over-rode the interatrial septum in 67 (70%) patients, with greater than 50% over-ride in 3 patients. CONCLUSION Anomalous connection of the right-sided pulmonary veins is universal, but is not limited to the right upper lobe. Not all individuals have over-riding of superior caval vein. In a minority of patients, the defect has significant caudal extension, and anomalously connected pulmonary veins are committed to the left atrium. These findings have significant clinical and therapeutic implications.

Abstract
Objectives To describe the outcomes of postoperative tracheostomy and determine the predictors of survival.
Design Prospective, observational study.
Setting Cardiac surgical intensive care unit of a tertiary care hospital.
Participants All pediatric patients below 10 years of age who underwent tracheostomy after cardiac surgery from January 2019 to December 2019. Different variables were compared between survivors and nonsurvivors.
Intervention Tracheostomy.
Results Among 1084 pediatric patients who underwent cardiac surgery during the study period, 41 (3.7%) received tracheostomy. Survival rate was 71%.Earlier, sternal closure (SC) (p = 0.04), acute kidney injury (AKI) (p = 0.001), serum C-reactive protein (CRP) (p = 0.007), duration of total parenteral nutrition (TPN) (p = 0.005) and days of feed interruption (FI) (p = 0.02), activated partial thromboplastin time (aPTT) before tracheostomy (p = 0.006), and bleeding from tracheostomy site (p = 0.02) were significantly low in the survivor group.Among the peritracheostomy variables taken at different time points, the levels of pH on tracheostomy day 1 (p = 0.03), serum lactate on tracheostomy day 2 (p = 0.01) and day 3 (p = 0.01), and random blood sugar (RBS) on tracheostomy day 3 (p = 0.04) were significantly lower in the survivor group.The arterial oxygen saturation (SaO2) on tracheostomy day 1 (p = 0.04) and the platelet count before tracheostomy (p = 0.02) were significantly higher in the survivor group.
Conclusions Our study demonstrated a survival of 71% among the study cohort. Lesser duration of open sternum, lower incidence of AKI, less number of days on TPN and FI, lower posttracheostomy aPTT, bleeding, RBS, lactate, and higher pretracheostomy platelet count and posttracheostomy SaO2 were found to be the predictors of survival.

Modified ultrafiltration and postoperative course in patients undergoing repair of tetralogy of fallot. J Card Surg 2021; 36:3679-3687. [PMID: 34324231 DOI: 10.1111/jocs.15841] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2020] [Revised: 06/08/2021] [Accepted: 06/15/2021] [Indexed: 11/27/2022]
Abstract
BACKGROUND Expected benefits of modified ultrafiltration (MUF) include increased hematocrit, reduction of total body water and inflammatory mediators, improved left ventricular systolic function, and improved systolic blood pressure and cardiac index (CI) following cardiopulmonary bypass (CPB). This prospective randomized trial tested this hypothesis. METHODS Seventy-nine patients undergoing intracardiac repair of tetralogy of fallot were randomized to conventional ultrafiltration (CUF) + MUF (n = 39) or only CUF group (n = 40). The primary outcome was a change in hematocrit. Secondary outcomes were changes in peak airway pressures, ventilatory support, blood transfusions, time to peripheral rewarming, mean arterial pressure, central venous pressure, inotrope score (IS), and CI. Serum inflammatory markers were measured. RESULTS Baseline hematocrit was 50.6 ± 10.02 in the only CUF group whereas it was 43.9 ± 5.55 in the CUF + MUF group (p = .36). Following MUF, the CUF + MUF group had higher hematocrit (44.7 ± 0.50 g/dl) compared to the only CUF group (37.2 ± 0.49 g/dl), p ≤ .001 after adjusting for baseline hematocrit. Central venous pressure (mmHg) immediately following sternal closure was 9.27 ± 3.12 mmHg in the CUF + MUF group and 10.52 ± 2.2 mmHg in the only CUF group (p = .04). In the intensive care unit (ICU), they were 11.52 ± 2.20 mmHg in the only CUF group and 10.84 ± 2.78 mmHg in the CUF + MUF group (p = .02). Time to peripheral rewarming was 6.30 ± 3.91 h in the CUF + MUF group and 13.67 ± 3.91 h in the only CUF group (p = .06). Peak airway pressures in ICU were 17 ± 2 mmHg versus 20.55 ± 2.97 mmHg in CUF + MUF group & only CUF group, respectively, p < .001). Duration of mechanical ventilation was 6.3 ± 2.7 h in CUF + MUF group compared to 14.7 ± 3.5 h in the only CUF group (p = .002). IS was 11.52 ± 2.20 in the only CUF group compared to 10.84 ± 2.78 in CUF + MUFs group. Eight of 39 (20.5%) patients in the CUF + MUF group had IS > 10 compared to 22 of 40 (55%) patients in the only CUF group (p = .02). Serum Troponin-T and interleukin-6 levels were lower in the CUF + MUF group; TNF-α and CPK-MB were similar. ICU and hospital stay were similar. CONCLUSION Patients undergoing a combination of CUF and MUF had higher postoperative hematocrit, decreased duration of mechanical ventilation, lower need for inotropes and lower interleukin-6 and Troponin-T levels. This group had better postoperative outcomes. This study was registered with the Clinical trials registry of India (CTRI/2017/11/010512) before commencement.

Abstract
OBJECTIVES This study sought to compare the efficacy of ivabradine and amiodarone in the management of postoperative junctional ectopic tachycardia (JET) after cardiac surgery in children. BACKGROUND JET is a serious arrhythmia occurring in children after cardiac surgery and requires aggressive management. Amiodarone has been conventionally used in its treatment. Recent studies have reported the utility of ivabradine in this regard. METHODS In this open-label randomized controlled trial, 94 children (age ≤18 years) who developed postoperative JET were allocated to receive either amiodarone or ivabradine. The primary endpoint was restoration of normal sinus rhythm. RESULTS Sinus rhythm was achieved in 43 out of the 46 patients (93.5%) in the amiodarone group and 46 out of the 48 patients (95.8%) in the ivabradine group (mean difference of treatment effect: 2.3%; 95% confidence interval: -6.7% to 11.5%). The median (interquartile range) time taken to achieve sinus rhythm conversion was similar in both the groups: 21.5 (17-30.2) hours versus 22 (13.4-38.5) hours (p = 0.36)]. The time taken to rate control of JET was significantly less in the amiodarone group: median 7.0 (5.5-9.5) hours versus 8.0 (5.8-10.8) hours (p = 0.02)]. No drug-related adverse events were observed in the ivabradine group. CONCLUSIONS Oral ivabradine is not inferior to intravenous amiodarone in converting postoperative JET to sinus rhythm. There was no difference in time taken to sinus rhythm conversion between the groups, although the rate control was earlier in patients who received amiodarone. Monotherapy with ivabradine may be considered as an alternative to amiodarone in the management of postoperative JET.

Abstract
Objectives This study was aimed to assess the benefits of early tracheostomy (ET) compared with late tracheostomy (LT) on postoperative outcomes in pediatric cardiac surgical patients.
Design Present one is a prospective, observational study.
Setting The study was conducted at a cardiac surgical intensive care unit (ICU) of a tertiary care hospital.
Participants All pediatric patients below 10 years of age, who underwent tracheostomy after cardiac surgery from January2019 to december2019, were subdivided into two groups according to the timing of tracheostomy: “early” if done before 7 days or “late” if done after 7 days postcardiac surgery.
Interventions ET versus LT was measured in the study.
Results Out of all 1,084 pediatric patients who underwent cardiac surgery over the study period, 41 (3.7%) received tracheostomy. Sixteen (39%) patients underwent ET and 25 (61%) underwent LT. ET had advantages by having reduced risk associations with the following variables: preoperative hospital stay (p = 0.0016), sepsis (p = 0.03), high risk surgery (p = 0.04), postoperative sepsis (p = 0.001), C-reactive protein (p = 0.04), ventilator-associated pneumonia (VAP; p = 0.006), antibiotic escalation (p = 0.006), and antifungal therapy (p = 0.01) requirement. Furthermore, ET was associated with lesser duration of mechanical ventilation (p = 0.0027), length of ICU stay (LOICUS; p = 0.01), length of hospital stay (LOHS; p = 0.001), lesser days of feed interruption (p = 0.0017), and tracheostomy tube change (p = 0.02). ET group of children, who had higher total ventilation-free days (p = 0.02), were decannulated earlier (p = 0.03) and discharged earlier (p = 0.0089).
Conclusion ET had significant benefits in reduction of postoperative morbidities with overall shorter mechanical ventilation, LOICUS, and LOHS, better nutrition supplementation, lesser infection, etc. These benefits may promote faster patient convalescence and rehabilitation with reduced hospital costs.

Abstract
Abstract
Background Delayed sternal closure (DSC) is being increasingly used as an interim support to help the dysfunctional heart in the road to recovery after complex pediatric cardiac surgeries. The purpose of this study was to assess the conduct of DSC at a tertiary care center.
Methods Between 2018 and 2019, 185 consecutive pediatric patients (below 12 years of age) underwent cardiac surgery at a tertiary care center. The incidence and causes of DSC were noted. The various pre, intra and postoperative factors till discharge or demise were noted and analyzed.
Results In this study, DSC was done in 63 patients (34.05%) with a median age and weight of 29 days (18–100 days) and 4 kg (2–12.3 kg), respectively. Transposition of great arteries (TGA) (41.27%) constituted the majority, followed by total anomalous pulmonary venous connection (TAPVC) (26.98%). Myocardial edema (49.21%) was the most common indication for DSC. Mean duration of open chest was 40.75 ± 18.58 hours. All-cause mortality was 19.05% (12/63). On multivariate analysis by logistic regression, the independent predictors of mortality were needed for preoperative mechanical ventilation (OR 42.82, 95% CI = 4.52–406.03, p < 0.001) and development of postoperative sepsis (OR 20.07, 95% CI = 2.12–189.80, p = 0.002).
Conclusions DSC is a safe and effective technique in the management of complex pediatric cardiac surgeries. It provides assistance to the severely dysfunctional myocardium soon after the surgery and helps in stabilization of hemodynamics with avoidance of postoperative mediastinal compression. Early sternal closure should be considered on the basis of cardiovascular function and/or resolution of primary indication for DSC.

Abstract
Background Health care is seriously affected by the coronavirus disease 2019 (COVID-19) pandemic with alarming effects upon conduct of cardiac surgery. The initial resource conservation strategy has to modify for handling the surging case load due to deference of routine care in the face of pandemic.
Methods The cardiac surgical practice during the lockdown period (from 25th march till 25th June) at a tertiary care centre was observed. The cardiac diagnosis of the ones operated, conduct algorithm, and working policy were analyzed. Descriptive statistics was applied to calculate the percentages of different case subsets in both adult and pediatric groups.
Results A total of 93 cardiac patients were consecutively operated during the 3 months’ period in two cardiac theatres of a total eight dedicated and were rotated cyclically. A total of 37 (39.78%) adult cardiac surgeries were performed out of 93 cases, with coronary artery bypass grafting (11.83%: 11/93) and valvular heart diseases (11.83%: 11/93) constituting the majority. Pediatric cardiac surgeries constituted 56 cases (60.21%) which comprised of arterial switch operation (19.35%), total anomalous pulmonary venous connection (8.60%), and Blalock Taussig shunts (7.53%) predominantly. There was no COVID-19-related mortality and none of the health-care workers developed COVID-19 in the entire study period.
Conclusions The initial phase of resource conservation has undermined the routine cardiac surgical practice. The study showed that strict adherence to management algorithm is necessary for persisting smooth continuation of cardiac surgical practice with provision of optimum critical care. The strategic comeback against COVID-19 would urge institutional development of protocols to aid the post-surge period.

Abstract
AbstractExtracorporeal membrane oxygenation (ECMO) has emerged as an effective mechanical support device to support both respiratory and cardiac function following cardiac surgery. The use of ECMO is more common among children who undergo complex surgical procedures. The objective of this study was to observe the outcomes of children subjected to central venoarterial (VA) ECMO after congenital cardiac surgery and identify the factors influencing survival in these children. Twenty children, below the age of 1 year, who underwent corrective cardiac surgery and were placed on ECMO support within first 48 hours of biventricular repair, from July 2018 to June 2019, were included in this study. ECMO was initiated either in the operating room (either preoperative decision or unable to come off cardiopulmonary bypass [CPB]) or in the intensive care unit (low-cardiac output syndrome). The maintenance and weaning from ECMO was done as per institute protocol. At the initiation of ECMO, the flows were maintained between 100 and 150 mL/kg/min. The flows were decreased if it was possible to maintain normal perfusion with lesser flows. Out of 20 children, 12 children were less than or equal to 2 months of age. The 30-day survival was 45% and all the children were alive at 4 months after discharge from hospital. A negative cumulative fluid balance (CFB) of more than 50 mL/kg in the first 48 hours, decreasing lactate and inotropic score, and improving ventricular function in the first 3 days of ECMO were associated with improved survival. The following factors were correlated with decreased survival: aortic cross-clamp time (AOCX T) more than 106 minutes, higher initial ECMO flows (75 vs. 52%), ECMO duration more than 4 days, increased transfusion of blood and blood products, urine output < 1.06 ± 0.81/kg/h (in the first 48 h), and increasing trend of C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR).

Abstract
JUSTIFICATION A number of guidelines are available for management of congenital heart diseases from infancy to adult life. However, these guidelines are for patients living in high income countries. Separate guidelines, applicable to Indian children, are required when recommending an intervention for congenital heart diseases, as often these patients present late in the course of the disease and may have co-existing morbidities and malnutrition. PROCESS Guidelines emerged following expert deliberations at the National Consensus Meeting on Management of Congenital Heart Diseases in India, held on 10th and 11th of August 2018 at the All India Institute of Medical Sciences, New Delhi. The meeting was supported by Children's HeartLink, a non-governmental organization based in Minnesota, USA. OBJECTIVES To frame evidence based guidelines for (i) indications and optimal timing of intervention in common congenital heart diseases; (ii) follow-up protocols for patients who have undergone cardiac surgery/catheter interventions for congenital heart diseases. RECOMMENDATIONS Evidence based recommendations are provided for indications and timing of intervention in common congenital heart diseases, including left-to-right shunts (atrial septal defect, ventricular septal defect, atrioventricular septal defect, patent ductus arteriosus and others), obstructive lesions (pulmonary stenosis, aortic stenosis and coarctation of aorta) and cyanotic congenital heart diseases (tetralogy of Fallot, transposition of great arteries, univentricular hearts, total anomalous pulmonary venous connection, Ebstein anomaly and others). In addition, protocols for follow-up of post surgical patients are also described, disease wise.

Abstract
Abstract
Objective Point of care (POC) testing-based algorithm-guided hemostatic therapy has been used in adult as well as pediatric cardiac surgical patients to administer blood components. The authors hypothesized that implementation of POC-based algorithm in pediatric cyanotic congenital surgical patients would reduce the exposure to blood component therapy and improve the clinical outcome.
Design Prospective randomized control trial.
Setting Single-center academic institute.
Participants One hundred seventy pediatric congenital cyanotic surgical patients.
Intervention Implementation of POC and conventional tests-based algorithms.
Measurements and Main Results Algorithm-based blood component therapy was administered in each group. There were no group differences regarding the demographic, clinical, and laboratory characteristics. Amount of packed red blood cells (PRBCs), fresh frozen plasma (FFP), platelets, and cryoprecipitate (primary outcomes) administered was significantly lower in POC group than that in the conventional group (p < 0.001). Among the secondary outcomes, the chest drain output at 6, 12, and 24 hours and number of re-explorations was comparable among both the groups. The duration of mechanical ventilation, duration of intensive care unit (ICU) stay, and hospital stay was significantly short in POC group (p = 0.008, <0.001 and 0.019, respectively).
Conclusion Implementation of POC-based algorithm-guided hemostatic therapy reduced the exposure to blood and blood component therapy and was associated with reduced ICU and hospital stay in pediatric congenital cyanotic surgical patients.

Abstract
AbstractAtrioventricular septal defect (AVSD) is the most common congenital cardiac anomaly associated with Down’s syndrome. Children with AVSD develop pulmonary arterial hypertension and often require extensive therapy with pulmonary vasodilators in the postoperative period. The postoperative management is complicated by prolonged mechanical ventilation through endotracheal tube or tracheostomy tube. This artificial airway may trigger various airway complications including subglottic tracheal stenosis. The incidence and severity of subglottic tracheal stenosis is high in children with congenital syndromes. Inability to extubate or decannulate trachea and rapid respiratory compromise while attempting to do so directs toward a diagnosis of subglottic tracheal stenosis. The following case report discusses a 2–year-old boy from Nigeria who was discharged with tracheostomy tube in situ due to severe subglottic tracheal stenosis and surgical tracheoplasty could not be done at his present age. The implications of prolonged tracheostomy tube in situ and the hazards thereof during transfer of the child are being described.

Abstract
Abstract
Background Data from many studies suggest that patients with congenital heart disease are vitamin D (vitD) deficient. Following cardiac surgery as a result of intraoperative institution of cardiopulmonary bypass (CPB), serum vitD levels become even low. This may affect postoperative convalescence in terms of mechanical ventilation, inotropic support, infection, and so forth.
Objective We intended to study the prevalence of vitD deficiency pre and post cardiac surgery and the effect of vitD supplementation (stoss therapy) on postoperative convalescence of the children with tetralogy of Fallot (TOF) undergoing intracardiac repair (ICR).
Methodology In this randomized controlled trial (RCT), 60 children younger than 18 years with TOF and serum vitD levels < 20ng/dL were randomized into two groups. The study group received vitD supplementation as “stoss therapy” at 10,000 units/kg body weight. All these children underwent ICR with CPB. Demographic data, preoperative, intraoperative, and postoperative variables were compared between the study and the control groups.
Results Prevalence of severe vitD deficiency was 93.1%. When compared with the control group, study group showed higher serum vitD levels in the immediate preoperative period (p = 0.001), postoperative period following CPB (p = 0.012), and on the first postoperative day (p = 0.003). No statistically significant difference was observed in postoperative mechanical ventilation (p = 0.35), intensive care unit (ICU) stay (p = 0.15), and inotropic duration (p = 0.19).
Conclusion Children with TOF are highly deficient of vitD, its level falls further after CPB, and supplementing vitD preoperatively does not influence postoperative recovery pattern. Supplementation of vitD as “stoss therapy” was useful in raising the serum levels before and after cardiac surgery.

Abstract
BACKGROUND Total Cavopulmonary connection (Fontan) is the final palliation for patients with a functionally univentricular heart. This is commonly accomplished after a prior bidirectional Glenn on cardiopulmonary bypass (CPB) with separate cannulation of the aorta, superior vena cava (SVC), and inferior vena cava. We describe an alternative technique of Fontan completion that eliminates the need for cannulation and dissection of the SVC, and pulmonary artery dissection. METHODS Between January and October 2018, 17 patients underwent completion Fontan using an alternate technique at our institute. All operations were conducted on CPB at normothermia without cannulating the SVC RESULTS: Mean CPB time was 60 ± 16.8 minutes (range, 39-102 minutes). There were no early deaths. Mean postoperative Fontan pressures were 15.6 ± 1.2 mm Hg with no gradient between the SVC and IVC pressures. Mean duration of hospital stay was 15.6 ± 3.6 days (range, 10-22 days). No patient developed phrenic nerve paresis or palsy. CONCLUSIONS Completion without cannulating the SVC is simple, reproducible, and easy to teach. It avoids the disadvantages associated with routine techniques.

Abstract
Quadricuspid aortic valve (QAV) is a rare congenital anomaly frequently associated with other anomalies particularly coronary anomalies. It may be detected on transthoracic or transesophageal echocardiography. We present here a case report of a 27-year-old male patient with a QAV, the valve being regurgitant and requiring aortic valve replacement. It has been reported as isolated case reports in the literature and various theories exist to the development of QAV. The diagnosis requires a high degree of suspicion and a detailed assessment, and if asymptomatic, then patients need to be carefully followed up for the development of aortic regurgitation.

Abstract
OBJECTIVE To evaluate the effect of autologous blood harvest (ABH)-induced volume shifts using electrical cardiometry (EC) in patients with pulmonary artery hypertension secondary to left heart disease. DESIGN Prospective, randomized, controlled trial. SETTING A tertiary care hospital. PARTICIPANTS The study comprised 50 patients scheduled to undergo heart valve replacement. INTERVENTIONS Patients were divided randomly into 2 experimental groups that were distinguished by whether ABH was performed. Blood volume extracted in the test group was replaced simultaneously with 1:1 colloid (Tetraspan; B Braun Melsungen, Melsungen, Germany). Hemodynamic, respiratory, and EC-derived parameters were recorded at predefined set points (T1 [post-induction/pre-ABH] and T2 [20 minutes post-ABH]). MEASUREMENTS AND MAIN RESULTS Withdrawal of 15% of blood volume in the ABH group caused significant reductions in thoracic fluid content (TFC) (-10.1% [-15.0% to -6.1%]); right atrial pressure (-23% [-26.6% to -17.6%]); mean arterial pressure (-12.6% [-22.2% to -3.8%]); airway pressures: (peak -6.2% [-11.7% to -2.8%] and mean -15.4% [-25.0% to -8.3%]); and oxygenation index (-10.34% [-16.4% to -4.8%]). Linear regression analysis showed good correlation between the percentage change in TFC after ABH and the percentage of change in right atrial pressure, stroke volume variation, autologous blood extracted, peak and mean airway pressures, and oxygen index. CONCLUSIONS In addition to its proven role in blood conservation, therapeutic benefits derived from ABH include decongestion of volume-loaded patients, decrease in TFC, and improved gas exchange. EC tracks beat-to-beat fluid and hemodynamic fluctuations during ABH and helps in the execution of an early patient-specific, goal-directed therapy, allowing for its safe implementation in patients with pulmonary hypertension secondary to left heart disease.

Abstract
OBJECTIVE Patients who have undergone a previous bidirectional superior cavopulmonary anastomosis and have hypoxemia and anatomy considered unsuitable for the Fontan completion present a difficult subset. We performed common carotid artery-to-internal jugular vein (CCA-IJV) shunt in these patients. METHODS Between January 2010 and January 2015, eight patients underwent a CCA-IJV shunt. Their records were analyzed retrospectively. RESULTS There were no early deaths. The baseline arterial saturation prior to the shunt procedure was median 67% (range 60%-72%), which increased to median 83% (range 80%-90%) after the procedure. The preoperative arterial oxygen partial pressure (Pao 2) ranged from 30 to 49 mm Hg (median 40 mm Hg). The hematocrit dropped from a preoperative median of 65% (range 55%-72%) to a median of 45% (range 42%-48%) after the procedure. Median intensive care unit stay was 2.5 days, and the median hospital stay was 7 days. Median follow-up was 24 months. At the last follow-up, these patients were classified in New York Heart Association class II. CONCLUSIONS In a selected group of patients who are considered to be unsuitable for completion of Fontan circulation following superior cavopulmonary anastomosis, creation of a CCA-IJV shunt may be helpful to improve saturations and improve ventricular function.

Abstract
Cortriatriatum with Raghib’s complex is a rarely reported entity. An 18-month-old baby who presented with tachypnea and cyanosis was diagnosed to have cortriatriatum sinistrum along with a persistant left superior caval vein draining to the left atrium through an unroofed coronary sinus. The child underwent successful surgical correction with excision of the cortriatriatum and baffling of the left superior caval vein to the right atrium.
