Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this bi-directional program of education, training and research activities based on sustainable development goals aim is to develop cardiac surgery service in Ethiopia.

The aim is to evaluate the short and long-term outcome of cardiac surgery for rheumatic heart disease in a low-income country compared to individuals not offered cardiac surgery due to limited availability of the service. Second aim is to evaluate the quality of anticoagulant therapy in patients after cardiac surgery for rheumatic heart disease in a low-income country .

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Our objectives are:

1. To evaluate the 30- and 180-days outcome of cardiac surgery for rheumatic heart disease (RHD), and impact of gender, age, clinical findings and echocardiographic classification, during the time of development of cardiac surgery at Black Lion hospital, Ethiopia, in comparison with matched individuals (from the same waiting list) which had no offer of surgery due to limited availability.
2. To evaluate the quality of anticoagulation therapy after cardiac surgery at Black Lion hospital, Ethiopia by evaluating the patients proportion of time in therapeutic INR-level, complications as valve dysfunction, bleeding and thrombosis compared to control patients undergoing valvular replacement due to RHD at Norwegian hospitals.

Population: Approximately 50 RHD patients operated by Our team at Addis Abeba University Hospital, Ethiopia.

Follow up for 180-days for objective 1 and continous follow-up for objective 2. Comparison With matched Controls. Outcome measures: Mortality, complications (heart failure, arrhythmias, thrombosis, bleedings, stroke, infections)
