Tricuspid atresia with normal axis on ECG palliated with a central shunt; a case report.

BACKGROUND: Tricuspid Atresia is the 3rd commonest cyanotic congenital Heart disease. It is characterized by lack of communication between the right atrium and right ventricle. The treatment often requires a palliative systemic to pulmonary shunt before definite surgery. The use of a central shunt via a median sternotomy is suggested here as an alternative to other traditional shunts via a thoracotomy. METHOD: The management of a 3-month-old boy who presented with dyspnoea, fever, cough and cyanosis is presented here as obtained from Clinical records. RESULT: Following resuscitation, a central shunt (Ascending Aorta to main Pulmonary Artery) was constructed and the patient did well despite a turbulent post-operative period. CONCLUSION: The management of tricuspid atresia likes other cyanotic heart disease is daunting but palliative treatment is possible in our environment and definitive treatment where possible affords a fairly satisfactory prognosis.

Cardiac pacemaker treatment of heart block in Enugu a 5-year review.

BACKGROUND: Symptomatic heart block is a treatable cardiac cause of death which occurs globally. In Nigeria it is increasingly diagnosed and treated with permanent artificial cardiac pacemaker insertion and pulse generator implantation, sometimes after a period of misdiagnosis and inappropriate treatment. METHODS: Twenty-three patients who were diagnosed with symptomatic heart block and surgically treated with permanent artificial cardiac pacemaker in National Cardiothoracic Centre, Enugu, between April 2001 and March 2006 had their case notes retrospectively reviewed and information entered into a proforma. This was analyzed. Patients diagnosed with symptomatic heart block but not treated with artificial cardiac pacemaker insertion were excluded from the study. There were eight such patients who could not afford the cost of surgical treatment during the period under review. RESULTS: The mean age of the patients was 70 years and the commonest presentation was shortness of breath (100%). Hypertensive heart disease was present in 65% of the patients and a history of chronic chloroquine usage was positive in 73% of the patients. Predominant pretreatment pulse rate was in the range of 30-40 per minute (43%) while 21% of the patients had pulse rate below 30 per minute. These categories of patients commonly had Stoke-Adams syndrome. Sixty-seven per cent of the patients had predominantly systolic hypertension on admission and 16% had hypotension. Third degree heart block was present in 65% of the patients and 89% of all patients needed pre-pacing haemodynamic stabilization with positive inotropic/chronotropic drug(s). Treatment consisted of permanent endocardial pacing in 65% and epicardial pacing in 35% of the patients with equally good response in symptoms, haemodynamic parameters and electrocardiographic features. CONCLUSION: Permanent artificial cardiac pacing is, the reliable treatment of symptomatic heart block and should be included in the National Health Insurance Scheme list.

Pregnancy after heart valve replacement--case report.

There is an increased risk of thromboembolism, anticoagulant-related haemorrhage, foetal-wastage, and congestive cardiac failure in pregnant women with mechanical heart valves. Pregnancy in such patients is a high risk venture. In order to have a good outcome, the care of such patients must necessarily be multidisciplinary and in a well-equipped centre with adequate support services. One such patient who had mechanical mitral valve replacement in 1986 and was on warfarin anticoagulant presented in April 2003 with a first trimester pregnancy. She was in stable haemodynamic state and went through pregnancy without event. Delivery was by an elective caesarian section at 38 weeks gestation. The care of this patient during pregnancy, delivery, and puerperium is the basis of this report.
