A STUDY ON PATTERN AND CLINICAL PROFILES OF CONGENITAL HEART DISEASES IN TERTIARY CARE CENTRE, KAKINADA.

BACKGROUND: Congenital heart disease is an abnormality of anatomical structure of the heart that is of paramount importance. The incidence is approximately 8 per 1000 live births. CHD not only contributes to signi?cant mortality and morbidity but also causes tremendous psychological stress and economical burden to whole family. OBJECTIVE: To study the pattern and clinical pro?le of congenital heart diseases in a tertiary care hospital and to aid for early stdetection and quick referral of children with congenital heart disease In this study, done between January 1 2020 to RESULTS: june 31st 2021, 54 children with con?rmed congenital heart disease were observed. ACHD was the most common type of CHD and of them, VSD was the most common type, followed by ASD. Based on sex distribution, 31 were male (55.5%) and 23 were female (44.5%), with a male: female ratio of 1.25:1. Most children belonged in the age group 6m – 1year (46.2%) followed by (42.5%) in 30days – 6months age. The common clinical presentation observed in this study was breathlessness. The common complication observed in the current study was heart failure followed by malnourishment and recurrent LRTI.

Double chambered right ventricle with ruptured sinus of Valsalva: rare entity

Valsalva sinus aneurysm (SVAs) and double-chambered right ventricle (DCRV)is an uncommon congenitalheart defect and are usually associated with ventricular septal defect (VSD) in 50% to 60% of patient抯 population. The current case report had documented a 59 years old hypertensive asymptomatic male with a known case of SVAs presented to our hospital following device closure for 6 months. On examination, the patient was diagnosed to have DCRV induced by SVAs prior to the closure along with other factors. However, to the best of our knowledge, this is the first case report on DCRV induced by SVAs in synergy with other associated multifactors and without VSD among the Indian population.

Application of WeChat Platform in Midterm Clinical Follow-Up of Children Who Underwent Transthoracic Device Closure of VSD

Abstract Introduction: The purpose of this study was to investigate the feasibility and superiority of using the WeChat platform for midterm clinical follow-up of children who underwent transthoracic device closure for ventricular septal defects (VSDs). Methods: Ninety children with VSDs who underwent transthoracic device closure were divided into a WeChat follow-up group (WFU group) and an outpatient follow-up group (OFU group). The patients were followed up via WeChat or at an outpatient clinic three months and one year after discharge. The incidences of adverse events, associated complications, costs and time spent, loss to follow-up rate, medication adherence, and overall satisfaction were recorded. Results: There was no statistically significant difference in the incidence of adverse events or postoperative complications between the two groups. Also, the loss to follow-up rate was similar between them. Compared with the OFU group, there were significant statistical advantages in the WFU group regarding the total time and cost spent, medication adherence, and satisfaction. Conclusion: The use of the WeChat platform in midterm clinical follow-up of children who underwent transthoracic device closure for VSDs has the advantages of reducing financial and time burdens, facilitating high medication adherence, and leading to high satisfaction.

Study the universal critical congenital heart disease screening in a peripheral area of Uttarakhand, India

Background: Congenital heart disease (CHD) is the most frequently occurring congenital disorder, responsible for 28% of all congenital birth defects. The birth prevalence of CHD is reported to be 8-12/1000 live births. Considering a rate of 9/1000, about 1.35 million babies are born with CHD each year globally. Objective of research work to study the prevalence of CHD among newborn and its types.Methods: This cross-sectional study was carried among 34 cases of CHD/5126 newborn screened at 4 birthing places in Kashipur a small town in Uttrakhand at pediatrics department of Sahota Super-specialty hospital, Kashipur, Uttarakhand. Screening program between 22 August 2014, and March 30, 2019. All newborns, including preterm babies, delivered in these facilities were eligible for inclusion in this study.Results: Present study found the prevalence of CHD was 0.7 per 1000 children (34/5126). Around 26.5% participants have cyanotic CHD and 73.5% have acynotic CHD. Almost 44%, 28%, 20%, 4% and 4% participants of acynotic congenital heart diseases have VSD, ASD, PDA, AVSD and valvular PS respectively and 55.6%, 22.2%, 11.1% and 11.1% participants of cynotic congenital heart diseases have TOF, DORV/VSD, dTGA/VSD and tricuspid atresia respectively.Conclusions: Screening for congenital heart disease should be included as a part of newborn assessment as it is a common congenital problem. Early identification influences outcome. Barriers in implementation of the screening programmes in resource limited setting is a challenging feature. This study can provide observed data that can help in policy making in the health sector.

A case of an uncorrected double outlet right ventricle with ventricular septal defect in pregnancy

Congenital Heart Diseases (CHD) lead to various changes in the normal mechanisms of hemodynamics. Pregnancy in women with CHDs is rare. Double Outlet Right Ventricle (DORV) is a rare disorder, in which both the aorta and the pulmonary artery arise from the right ventricle. We present a case of a thirty-year-old pregnant woman who presented to us with 22 weeks of amenorrhea. She had DORV with VSD, which was undiagnosed till she came to our hospital. Double Outlet Right Ventricle (DORV) is a rare congenital heart disease. Pregnancy in a patient with DORV needs early diagnosis and a stepwise multidisciplinary approach for successful outcomes.

Cardiovascular disease in pregnancy

Background: Maternal cardiac disease is a major cause of non-obstetric maternal morbidity and mortality. The care of pregnant women with cardiac disease requires a multidisciplinary approach, involving obstetricians, cardiologists and anesthesiologist.Methods: A prospective analytical study of maternal heart disease and its fetomaternal outcome is carried out in the department of obstetrics and gynecology at tertiary hospital and teaching institute. The study was carried out on 50 cases belonging to age group 18-50 years with various cardiac diseases during their pregnancy and peripartum period.Results: In this study, 78% of the cases were registered with our hospital. The present study shows about 32% of the women having cardiac disease were in the age group of 20-25 years. 34% belonged to NYHA class II and had a relatively uneventful peripartum period. Among all forms of heart disease, RHD was common constituting 26% of cases. Most common condition associated with cardiac disease in pregnancy was preeclampsia (36%) in our study, with anemia being other one (10%). The common complications were congestive cardiac failure (12%) and pulmonary edema (8%). Combination of diuretics and beta blockers was used most commonly (22%). 56% of women delivered with caesarean section. 42 patients delivered after age of viability with 29 (69%) term deliveries and 13 (30%) preterm deliveries with 8 requiring NICU care.Conclusions: Valvular heart disease of rheumatic origin is the most common cardiac disease associated with pregnancy.The availability of adequate systems of early diagnosis of cardiac lesion, reference to tertiary care center & close monitoring of patient and delivery with multidisciplinary approach include specialized cardiologic care, high risk obstetric support and neonatology expertise that can minimize the serious consequences and helps to improve fetomaternal outcome. Pre-conceptional counseling and surgical correction of certain conditions improves maternal as well as fetal outcome. Awareness needs to be created about heart diseases during pregnancy and the importance of regular antenatal check-ups.

A study of prevalence and pattern of congenital heart disease at Sopore, Kashmir, North India

Background: Early detection of congenital heart disease is of paramount importance to improve the quality of life of children and prevent morbidity and mortality. Congenital heart disease (CHD) is one of the major causes of mortality and morbidity in the pediatric population of both the developing and developed countries. Present aim was to study the prevalence, age and sex wise distribution, and clinical spectrum of congenital heart disease (CHD) at Sopore, Kashmir, North India.Methods: Around 39829 children in the age group 0 months to 18 years were screened for Defects at birth, Diseases in children, Deficiency conditions and Developmental Delays including Disabilities over the period of 18 months under RBSK. Clinical examination, echocardiography and color Doppler were used as diagnostic tools.Results: A prevalence of 5.3 per 1000 population was observed. VSD (ventricular septal defect) was the commonest lesion (30.1%), followed by PDA (patent ductus arteriosus) in 21.6 % and ASD (atrial septal defect) in 20.2%. Tetralogy of Fallot was the commonest cyanotic heart disease (8.0%). Maximum numbers of children with heart disease were diagnosed in the age group 6 weeks to 6 years.Conclusions: For better estimation of prevalence of congenital heart diseases, more elaborate community-based studies are needed. Such community based studies can be easily done by collecting and analyzing data collected from screening programs like RBSK. Such community based screening programs helps in detecting silent cardiac ailments, their prevalence and pattern, and early therapeutic intervention. A few prevalence studies have been carried out piecemeal in different locations of India; and more such studies can be easily done by collecting and analyzing data collected under RBSK screening program.

Single patch closure of multiple VSDs through right atrial approach

Multiple ventricular septal defects (VSD) are traditionally considered as surgical challenges and often ventriculotomy is needed. We report our experience with single patch closure of multiple VSDs in 4 children with a median weight was 5.6 kg. VSDs were closed via right atrium with a single Goretex patch with no operative death and short mean intensive care stay. To conclude, surgical approach to multiple VSDs is still a challenge, but a select approach to septate through right atrium adds to the surgical armamentarium to handle this difficult problem.

Transcatheter closure of ventricular septal defect in aortic valve prolapse and aortic regurgitation

Objective To report intermediate follow-up result of transcatheter closure of ventricular septal defect (VSD) in presence of aortic valve prolapse (AVP) with or without aortic regurgitation (AR). Method This is a retrospective review of 19 patients with VSD with AVP with AR who underwent transcatheter closure in between September 2011–July 2014. Mean age was 8 years (1–16 years, standard deviation [SD] 4.08 years) and mean weight was 26.03 kg (9–81.5 kg, SD 16.57 kg). Among them 2 had subarterial VSD, 6 had subaortic VSD and 11 had perimembranous VSD. All of them had mild AVP and 13 of them had AR (trivial or mild). Median VSD size was 4.3 mm (4–6 mm). Transcatheter closure was done either by retrograde technique using the Amplatzer Duct Occluder-II in 17 patients or antegrade technique using the Duct Occluder-I in 2 cases. Mean follow-up period was 18 months (12–36 months). Result Immediate major complications were encountered in 2 (10.5%) cases. Significant aggravation of device related AR was seen in one case & device embolised to right pulmonary artery in another case and both of them were managed surgically. During follow up, 1 child had significant additional VSD requiring device closure. One child developed moderate AR, requiring surgery. None of the other had shown any increase in severity of AR. Conclusion Device closure of VSD in presence of mild AVP and mild AR appears to be safe. Longer follow-up is necessary to draw final conclusion.

Finite Element Modeling and Analysis of Ventricular Septal Defect Occluders / 医用生物力学

Objective To analyze influences of the braiding angle and material on performance of ventricular septal defect (VSD) occluders, so as to provide theoretical basis and guidance for their design. Methods The finite element models of occluders with different braiding angles (30°, 45° and 60°) were developed respectively. The radial supporting and axial bending performances of nickel titanium (NiTi) occlude and poly-p-dioxanone (PPDO) occlude were then compared. Results Under 5 kPa radial loading, radial stiffness of the 30°, 45° and 60° NiTi occluder waists were 8.60, 1.51 and 0.99 mN/mm3,respectively, while that of 45° PPDO occluder waist was 7.35 mN/mm3. Under axial bending of 0.5 rad, the maximum radial deformation of the 30°, 45°, 60° NiTi occluder waists were 1.17, 1.24 and 0.22 mm, while that of the 45° PPDO was 0.54 mm. Conclusions Under the condition of using the same material, occluders with braiding angle of 60° show the lowest radial stiffness, indicating they have the best radial supporting ability. Furthermore, they also show the smallest maximum radial deformation, indicating they have the best axial bending ability and the compliance. On the other hand, under the condition of using the same braiding angle, NiTi occluders show lower radial stiffness, indicating they have better radial supporting ability. However, PPDO occluders show lower maximum radial deformation, indicating they have better axial bending ability and compliance.

Profile of Acyanotic Congenital Heart Defects

Background: Acyanotic CHD constitute majority of heart defect with significant morbidity, Profile of various defects is essential for identifying children who need urgent intervention and who need to be medically followed. Methods: The study was carried out in Department of Pediatrics and Center of Cardiology, Jawaharlal Nehru Medical College, Aligarh. All patients referred with complaints or clinical examination suggestive of congenital heart defects were further evaluated with echocardiography. On echocardiography patients having congenital heart defects were included as cases which were further divided into cyanotic and acyanotic heart defects, preterms having PDA and PFO and those with acquired heart defects were excluded. The profile and mode of presentation of various acyanotic CHDs was further described in detail. Results: Acyanotic heart defects were 290(72.50%) of the total heart defects, while the contribution of cyanotic heart defects was 110 (27.50%). Out of all CHDs, VSD was the most common lesion with contribution of 152 (38.00%) cases, followed by ASD (20.34%) , PDA (13.10%), PS (6.90%), Subaortic Membrane (2.00%), AV Canal valve defect (1.00%), RSOV (1.00%), Bicuspid Aortic Valve (1.00%), PAPVC (0.66%), Cortriatriatum (0.33%), Coarctation of Aorta(0.33%), ALCAPA(0.33%) and Aortic stenosis (0.33%). Age of presentation for most of the children was between 1 to 5 years. Conclusions: The profile and mode of presentation of various acyanotic heart defects was similar to other studies but diagnosis was delayed in majority of cases. The prevelance of various obstructive lesions like AS, coarctation and bicuspid aortic valve was much lower.

An Asymptomatic Double Outlet Right Ventricle (DORV).

Endophytic Association of Trichoderma asperellum within Theobroma cacao Suppresses Vascular Streak Dieback Incidence and Promotes Side Graft Growth

Trichoderma species are able to persist on living sapwood and leaves of cacao (Theobroma cacao) in an endophytic relationship. In this research, we evaluated the ability of Trichodema asperellum introduced at the incision site in the bark for side grafting with the concentration of 4 g/10 mL, 4 g/100 mL, and 4 g/1,000 mL (suspended in water) in suppressing vascular streak dieback (VSD) incidence and promoting growth of side grafts in the field. The incidence of VSD in two local clones of cacao, MCC1 and M04, without application of T. asperellum was 71.2% and 70.1% at 21 wk after grafting, respectively. However, when the two clones were treated with a concentration of 4 g/10 mL T. asperellum, the incidence was 20.6% and 21.7%, respectively, compared to 29.1% and 20.9% at 4 g/100 mL and 18.2% and 15.6% at 4 g/1,000 mL. By comparing to the control, the treatment with the same concentrations of T. asperellum listed above, the total number of stomata in MCC1 decreased by 41.9%, 30.2%, and 14.0% and in M04 by 30.5%, 21.9%, and -2.5% (exception), respectively. Otherwise, the total area of stomata opening increased by 91.4%, 99.7%, and 28.6% in MCC1 and by 203.8%, 253.5%, and 35.9% in M04, respectively. Furthermore, the number of buds and branches treated with a mixture concentration on the the two clones increased by 90.7% and 21.7%, respectively. These data showed that the application of T. asperellum to cacao scions while grafting can decrease VSD incidence in side grafts and increase growth of grafts in addition to decreasing total number of stomata, increasing total area of opened stomata, and increasing number of buds and branches.

Application of damage control surgery in treatment of severe electric burn / 实用医学杂志

Objective To explore the effect of damage control surgery (DCS) in the treatment of severe electric burn. Methods Retrospective analysis on clinical data of 45 patients with severe electric burn was con-ducted. According to implementing DCS or not , patients were separated into DCS group and control group. In DCS group, tangential excision and transplanted xenogenic acellular dermal matrix was conducted for severe electric burn cases with deep Ⅱ degree wound, and escharectomy and VSD dressing for Ⅲ~Ⅳ degree electric contact burn wound at the first stage then skin-grafting or skin flap-grafting on the secong stage was applied. For control group , debridement, tangential excision or escharectomy and skin-grafting or skin flap-grafting to close the wound were conducted. We compared the difference in terms of operation time, length of stay, disability rate, mortality and complications between 2 groups. Results The operation time, incidince of disability and complications in DCS Group obviously decreased but there was no difference in length of stay and mortality in both groups. Conclusion DCS is effective for reducing complications and optimizing therapeutic effect for severe electric burn patients.

Morphometric and Clinical Analysis of Moderator Band in Humans.

Background: The moderator band has the right bundle of His within the right ventricle. It also is known to prevent the over dilatation of RV. It is important because of its involvement in RV infarcts, in differentiating RV from LV in congenital anomalies, in VPDs & VTs and in VSDs. The present literature is very much lacking in its morphometry. Materials and Methods: Moderator band was looked for in 50 hearts and only in this study did we find it in all the hearts. The length, the thickness, the distance from the tricuspid valve along with the presence of any trabeculations in the septal end or in the papillary muscle end were looked for and recorded. Results: The average length was 14.71±4.99mm, the average thickness was 4.97±1.64 mm, the average distance from the tricuspid orifice was 19.85±5.92 mm. The attachment to the anterior papillary muscle was found to be branched in 8 hearts that is having an incidence of 14% . The septal end were branched and separated as two in only two specimens. Only one specimen had branched attachments on both the apical and septal ends. Conclusion: The distance from tricuspid valve and knowledge of branching are important in corrective surgeries of the VSDs. An awareness of length and thickness helps the clinician to differentiate moderator band from the other structures, which may result in misdiagnosis during echocardiography. Its presence may in fact be of significance in preventing over distension of the heart in RV myocardial ischaemia.
