AETIOLOGY OF TRICUSPID REGURGITATION
AbstractBackground: Tricuspid regurgitation (TR) is regarded as a secondary disorder. Aim of the study wasto know what percentage is secondary to heart and lung disease and its prevalence in normal adults.Methods: Two hundred and 30 adults with clinically detectable TR were studied clinically to know thecause of TR. Results: Thirteen percent of the adults were normal without any detectable cause for TR.In others, 24% of TR cases were secondary to ischemic heart disease (IHD) and hypertension wasfound in 14% cases. Sixteen percent had rheumatic heart disease (RHD) while chronic obstructive lungdisease was found in 23% cases. The rest of 10% cases of TR had cardiomyopathy (CMP) andcongenital heart disease as secondary causes. Conclusion: Ischemic heart disease, COPD andhypertension are common causes of TR. Others include RHD, CMP and congenital heart disease.Thirteen percent of apparently normal adults had TR.Keywords: Tricuspid regurgitation, IHD, Hypertension, COPD
