Study of cardiac function in adults with dengue

Background: Medical literature has reports of isolated cases of atrioventricular conduction disorders, supraventricular arrhythmias, and myocarditis in dengue fever (DF).There is a paucity of data available in the published literature on the cardiac manifestations of DF from India. The aim of the present study was to assess the cardiac manifestations of DF. Methods: The140 patients aged ?18 years with DF confirmed with a serology-dengue non-structural protein 1 antigen-positivewere included for this prospective observational study. Three serial ECGs were taken on day one, day three and day seven or day of discharge. All the patients were evaluated using 2D echo on day one, day seven or day of discharge. The primary outcome measures were to find the incidence and type of echocardiographic abnormalities and electrocardiographic changes in dengue.Results: The incidence of cardiac abnormalities on ECG and 2D echo was 30 (21.4%), and 5 (7.0%) respectively. On ECG, 14 (10%) 9 (6.4%) 3 (2.1%) 3 (2.1%) and 1 (0.7%) patients had sinus bradycardia, sinus tachycardia, non-specific ST-T changes, right bundle branch block and atrio-ventricular block respectively. On 2D echo, 7 (5.0%), 5 (3.6%) and 1 (0.7%) patient had systolic dysfunction, ejection fraction (<45.0%) and diastolic dysfunctionrespectively. Conclusions: The incidence of cardiac abnormalities on ECG and 2D ECHO in dengue patients was considerable. ECG and 2 D echo should be undertaken in patients with DF.

Diagnóstico prenatal de arco aórtico derecho fetal con anillo vascular / Prenatal diagnosis of fetal right aortic arch with a vascular ring

Resumen Las anomalías del arco aórtico se refieren a malformaciones congénitas de la posición o patrón de ramificación. Se pueden detectar mediante la visualización dirigida del corte de los tres vasos o de tres vasos y tráquea, con o sin Doppler de color. El diagnóstico prenatal debe conllevar un examen detallado de ultrasonido cardiaco y extra-cardiaco. La identificación de un arco aórtico derecho aislado es crucial para distinguir esta afección del arco aórtico doble. Se describe un caso de diagnóstico prenatal de arco aórtico derecho fetal con anillo vascular a las 29 semanas de gestación, quien fue referido por posible anomalía cardíaca en la ecografía de rutina. El ultrasonido demostró posición anormal de la aorta descendente, situada en el lado derecho de la columna vertebral en el plano tetracameral. La aorta se conectaba con la arteria pulmonar izquierda a través del ductus arterioso, configurando un anillo vascular. La detección prenatal de esta anomalía congénita vascular, ya sea de forma aislada o en asociación con otras malformaciones cardiacas o no cardiacas, podría conducir a un asesoramiento más adecuado.

Abstract Aortic arch anomalies refers to congenital malformations of the position or branching pattern. They can be detected by targeted visualization of the three-vessel slice or three-vessel and trachea, with or without color Doppler. Prenatal diagnosis should involve a detailed cardiac and extra-cardiac ultrasound examination. The identification of an isolated right aortic arch is crucial to distinguish this condition from a double aortic arch. We describe a case of prenatal diagnosis of fetal right aortic arch with vascular ring at 29 weeks gestation who was referred for possible cardiac anomaly on routine ultrasound. Sonography demonstrated abnormal position of the descending aorta, located on the right side of the spine in the tetra chamber plane. The aorta was connected to the left pulmonary artery through the ductus arteriosus, configuring a vascular ring. Prenatal detection of this congenital vascular anomaly, either in isolation or in association with other cardiac or noncardiac malformations, could lead to more appropriate counseling.

Síndrome de hipoplasia del ventrículo izquierdo / Left ventricular hypoplasia syndrome

Antecedentes: el síndrome de hipoplasia del ventrículo izquierdo es un conjunto de alteraciones del corazón fetal que condicionan un hipodesarrollo del corazón izquierdo, que es insuficiente para mantener la circulación sistémica. El corazón derecho se encuentra dilatado e hipertrofiado y soporta la circulación pulmonar y la circulación sistémica fetal a través del conducto arterioso permeable. Representa el 2 a 3% de todas las cardiopatías congénitas. Sin embargo, la incidencia real está subestimada ya que es responsable de abortos espontáneos y otras muertes fetales intrauterinas no diagnosticadas. Reporte de un caso: paciente de sexo femenino, 32 años de edad, con antecedente familiar de importancia (padre con fibrilación auricular). Antecedentes gíneco-obstétricos: un parto céfalo-vaginal, sin complicaciones, de un neonato de sexo masculino que actualmente tiene 6 años de edad. Durante su segunda gesta el feto es diagnosticado de hipoplasia del ventrículo izquierdo y atresia de la válvula mitral a las 34 semanas. Acude al Hospital Metropolitano a las 39 semanas de gestación para terminación de su embarazo mediante parto céfalo-vaginal. El parto no tuvo complicaciones; al nacimiento se confirma el diagnóstico prenatal y el recién nacido fallece en las primeras 72 horas. Conclusiones: el síndrome de hipoplasia del corazón izquierdo es una combinación compleja de malformaciones cardíaca;, debe ser detectado durante la evaluación ecográfica prenatal para planificar su manejo al nacimiento en centros especializados donde sea posible realizar procedimientos con el propósito de mejorar la supervivencia de estos pacientes.

Background: It is a set of alterations of the fetal heart that condition a hypodevelopment of the left heart, which is insufficient to maintain the systemic circulation. The right heart is dilated and hypertrophied and it supports the pulmonary circulation and fetal systemic circulation through patent ductus arteriosus. It represents 2 - 3% of all congenital heart diseases. However, current incidence is underestimated because it produces spontaneous abortions and other undiagnosed intra- uterine fetal deaths. Report of a case: a 32-year-old female patient with an importance family history: father with atrial fibrillation. Obstetric-gynecological antecedents: a cephalo- vaginal delivery without complications who was a male product of 6 years. During her second pregnancy, fetus was diagnosed with left ventricular hypoplasia and mitral valve agenesis at 34 weeks. She went to Metropolitan Hospital at 39.1 weeks to finish her pregnancy due to cephalo-vaginal birth. Delivery occurred without complications, however, the prenatal diagnosis was confirmed and the newborn died in 72 hours. Conclusions: The left heart hypoplasia syndrome is a complex combination of cardiac malformations; it can be detected with a prenatal evaluation with ultrasound which provides an option to pose treatment and also it can guide physicians to prepare for postnatal interventions when it is necessary.

Effect of transthoracic minimally invasive intervention in treatment on congenital heart disease complicated with compound deformities / 中华实用儿科临床杂志

Objective To explore the safety and therapeutic effect of transesophageal echocardiography(TEE)-guided transthoracic minimally invasive intervention for congenital heart disease complicated with compound heart ab-normalities in children.Methods From September 2013 to January 2018,32 children with congenital heart disease complicated with compound heart abnormalities were collected,who undergoing TEE-guided transthoracic minimally invasive intervention at the Department of Cardiothoracic Surgery,Dalian Children's Hospital were collected.There were 6 cases of ventricular septal defect (VSD)combined with atrial septal defect (ASD),11 cases of VSD combined with patent ductus arteriosus (PDA),9 cases of ASD combined with PDA,3 cases of VSD combined with pulmonary stenosis (PS),and 3 cases of ASD combined with PS.TEE-guided transcatheter closure was performed within a minimally in-vasive transthoracic minimal incision (1 -2 cm)under non-cardiopulmonary bypass.The efficacy of the procedure was evaluated by TEE.The transthoracic echocardiography,chest film and cardiogram after post-procedure examina-tions were followed.Results TEE-guided transthoracic minimally invasive perventricular intervention was successfully performed in all the sick children.The mean duration of operation,intensive care unit monitoring and ventilation were (54.2 ± 21.8)min,(14.3 ± 8.7)h and (3.7 ± 2.9)h,respectively.No patient received diuretic drugs,sedation drugs,blood transfusion or conventional surgical repair. The follow - up period for all the patients lasted 12 -48 months.No arrhythmias,residual shunts or occluder detachments,or thrombosis,hemorrhage,or new valve regurgitation occurred.Conclusions TEE -guided transthoracic minimally invasive intervention is feasible and has a promising prognosis for young children with congenital heart disease combined with compound heart abnormalities.

Cardiac Abnormalities in Psoriasis

Introduction: Psoriasis is considered an independent cardiovascular risk factor. This study aims to determine and describe the cardiac abnormalities using echocardiography and electrocardiography in patients with plaque psoriasis. Methods: This is a case control study of psoriasis patients with no previous history of cardiac disease. One hundred and thirty-five patients attending the Dermatology Clinic, Hospital Kuala Lumpur were recruited over one year. A full history, physical examination, echocardiogram and electrocardiogram were done. The controls were 135 age and sex matched healthy individuals. Results: The psoriasis group had a significantly higher body mass index and blood pressure. The echocardiogram showed that the mean left ventricular wall diastolic thickness, aortic annulus diameter and isovolumetric relaxation time of the left ventricle was significantly prolonged, and a higher prevalence of tricuspid regurgitation in psoriasis. On the electrocardiogram, more psoriasis patients had left ventricular hypertrophy, ischaemia and right bundle branch block. The QRS interval was significantly shorter in these patients. The tricuspid valve E/A ratio was significantly lower in patients with psoriatic arthropathy. The mitral valve early filling velocity deceleration time, tricuspid valve E/A ratio and QRS interval were significantly higher among systemic therapy naïve patients. The mean mitral and tricuspid valve E/A ratio were significantly lower; and the mean ascending aorta diameter larger, in those with psoriasis for more than ten years. Conclusion: Psoriasis may be associated with an increased risk of cardiac abnormalities suggesting diastolic dysfunction and tricuspid regurgitation. These abnormalities appear to be related to disease duration. Further studies employing newer echocardiographic and cardiac imaging techniques are needed to validate this.

Cardiac Abnormalities in HIV Infected Children Presenting to a Tertiary Level Teaching Hospital at New Delhi.

Aims: The aim of our study was to study the prevalence of various cardiac abnormalities in HIV positive children. Study Design: Cross sectional observational study. Place of Study: Antiretroviral treatment clinic of Maulana Azad Medical College and associated Lok Nayak Hospital and Department of Cardiology at G.B.Pant Hospital ,New Delhi . Duration of study : March 2009 to Mar 2010. Methodology: Sixty perinatally acquired, HIV-positive children asymptomatic for cardiac disease in age group of 0-12 years were evaluated for cardiac abnormalities by echocardiography. All children were classified according to the WHO clinical staging for HIV-positive children and also divided into immunologic category as per the age-specific CD4-T lymphocyte count. Results: Sixteen (26.6%) children had evidence of cardiac abnormalities on echocardiography. Twelve (20%) patients in WHO stage III and IV had significant abnormal echocardiographic findings. The major echocardiographic findings seen were left ventricular dilatation in 4 (6.7%) and left ventricular diastolic dysfunction in 3 (5%) children. Conclusions: A baseline echocardiographic study should be done in all patients with symptomatic HIV infection at first contact. Serial echocardiographies should be done to determine the evolution of cardiac disease in HIV infected children. Echocardiographic abnormalities are present even in HIV- infected children who are asymptomatic for cardiac dysfunction.

OBJECTIVE: To investigate the frequency, type and severity of cardiac abnormalities in the patients with ankylosing spondylitis and undifferentiated spondyloarthopathy. METHODS: A history, clinical examination, standard 12 lead electrocardiography, two dimensional, M mode, and Doppler echocardiographies were performed on 19 patients with ankylosing spondylitis, 15 patients with undifferentiated spondyloarthropathy and 21 normal controls. RESULTS: 1) Cardiac abnormalities were detected in 8 patients(42.1%) with ankylosing spondylitis. 2) Cardiac abnormalities were detected in 8 patients(53.3%) with undifferentiated spondyloarthropathy including 2 patients with aortic valve abnormalities(mild aortic insufficiency, aortic valve thickening. 3) Cardiac abnormalities were detected in one (4. 8%) among normal controls (mild tricuspid regurgitation). 4) There were sinus bradycardias on electrocardiography in 2 patients among patients witn anl;ylosing spond!litis and in 1 patient among undifferentiated spondyloarthropathy. But there was no conduction disturbance in both groups. 5) The frequency of cardiac abnormality was higher in patients with ankylosing spondylitis and undifferentiated spondyloarthropathy than in normal controls. 6) The mean age, mean disease duration, presence of uveitis, peripheral arthritis, HLA-B27, enthesopathy, Schober test and chest expansion in the patients with ankylosing spondylitis and undifferentiated spondyloarthropathy with cardiac abnormalities were not different from those in the patients without cardiac abnormalities. CONCLUSION: The frequency of cardiac abnormality was higher in patients with ankylosing spondylitis and undifferentiated spondyloarthropathy than in normal controls. The frequency, type and severity of cardiac involvement in patients with ankylosing spondylitis were not different from those in patients with undifferentiated spondyloarthropathy.
