We reported a case of a 29-year-old man who had been in good health until contracting brain stem encephalitis due to a rubella virus 5 years previously, at which time the ECG revealed complete right bundle branch block and right axis deviation. An ECG obtained 6 months earlier had been within normal limits. Since yearly health checkups continued to show the same abnormalities, the patient was admitted for closer examination. At the time of admission, physical findings and blood tests revealed no abnormalities. No cardiomegaly nor pulmonary congestion was observed on chest X-rays either at the time of the original illness or at this time. An endomyocardial biopsy specimen obtained from the right ventricle revealed size variation of cardiac myocytes, moderate disarrangement, and mild myocardial interstitial fibrosis, indicative of post-myocarditic changes. The above findings suggest that bifascicular block (right bundle branch and posterior fascicle) appeared at the time of the rubella virus infection, in the pathogenesis of which the involvement of myocarditis was strongly suspected. Some patients developing myocarditis do not manifest cardiac symptoms such as heart failure. In these cases, conduction disturbances are the sole sequelae. To differentiate pathogenesis in such cases, endomyocardial biopsy was thought to be of value.

Two cases of rubella myocarditis are reported: a 6-year-old boy who developed a complete, distal to His, atrioventricular block, during the third day of illness; and a 12-year-old boy who developed myocarditis with congestive heart failure 20 days following rubella infection. Although permanent pacing was required in the first patient, six years later he showed a normal growth and maintained normal activity. The second patient has deteriorated markedly and 6 months after the initial illness he had severe heart failure. It should be noted that myocarditis with abnormalities of the conduction system or congestive heart failure may be a complication to postnatal rubella.

Of 880 patients who attended the paediatric cardiology unit, University College Hospital, Ibadan, during a ten-year period, 635 (72.2%) had congenital cardiac malformations. Ventricular septal defects were the commonest lesions (35% of the 635 cases), followed by patent ductus arteriosus (22%), Fallot's tetralogy (10%), pulmonary stenosis (9%) and atrial septal defects (7.5%). Coarctation of the aorta was uncommon (2%) and aortic stenosis rare (0.6%). The overall sex incidence was even. Aetiological factors were ascertained in 72 cases (11%). In 60% of these cases intra-uterine rubella was responsible and in 18% perinatal asphyxia. In most patients the cardiac malformation was detected late; consequently complications, such as heart failure, pulmonary hypertension, and polycythaemia were common, even in new patients. Sixty-seven patients (11%) died in hospital, mostly from surgical intervention, heart failure, hypoxaemia, bronchopneumonia and associated extracardiac defects. It is suspected that hypocalcaemia, resulting from vitamin D deficiency may be a cause of the observed low prevalence of obstructive aortic lesions. We suggest that cardiac evaluation be performed at birth in postnatal clinics and in immunization centres, in order to facilitate early detection and treatment of congenital heart disease.

An 11-year-old female patient, whose systemic type juvenile idiopathic arthritis (JIA) had maintained in remission for the previous 4 years while taking only a small amounts of ibuprofen, showed an abrupt 2nd relapse with congestive heart failure five days after receiving a live-attenuated rubella vaccine, which was a primary immunization. Her serum levels of anti-rubella IgM and IgG antibodies increased, and her laboratory findings such as a leukocytosis, elevated serum levels of CRP, IL-6 and other inflammatory cytokine profiles were similar to the findings observed during her previous JIA active stage. After being administration of co-therapy with steroid pulse, ibuprofen, methotrexate and phosphodiesterase inhibitor gradually improved her clinical symptoms such as spiky fever, heart failure and arthralgia. Her intermittent fever and increased serum levels of CRP and IL-6, however, have been sustained for more than 2 years, and this prolonged active clinical course therefore differed from her previous JIA active stage.This abrupt relapse only five days after vaccination was suggested not to be directly related with rubella infection, but instead to be related with the molecular mimicry between rubella and JIA.

The congenital heart disease includes abnormalities in heart structure that occur before birth. Such defects occur in the fetus while it is developing in the uterus during pregnancy. About 500,000 adults have congenital heart disease in USA (WebMD, Congenital heart defects medications, www.WebMD.com/heart-disease/tc/congenital-heart-defects-medications , 2014). 1 in every 100 children has defects in their heart due to genetic or chromosomal abnormalities, such as Down syndrome. The excessive alcohol consumption during pregnancy and use of medications, maternal viral infection, such as Rubella virus, measles (German), in the first trimester of pregnancy, all these are risk factors for congenital heart disease in children, and the risk increases if parent or sibling has a congenital heart defect. These are heart valves defects, atrial and ventricular septa defects, stenosis, the heart muscle abnormalities, and a hole inside wall of the heart which causes defect in blood circulation, heart failure, and eventual death. There are no particular symptoms of congenital heart disease, but shortness of breath and limited ability to do exercise, fatigue, abnormal sound of heart as heart murmur, which is diagnosed by a physician while listening to the heart beats. The echocardiogram or transesophageal echocardiogram, electrocardiogram, chest X-ray, cardiac catheterization, and MRI methods are used to detect congenital heart disease. Several medications are given depending on the severity of this disease, and catheter method and surgery are required for serious cases to repair heart valves or heart transplantation as in endocarditis. For genetic study, first DNA is extracted from blood followed by DNA sequence analysis and any defect in nucleotide sequence of DNA is determined. For congenital heart disease, genes in chromosome 1 show some defects in nucleotide sequence. In this review the causes, diagnosis, symptoms, and treatments of congenital heart disease are described.
