FREQUENCY OF ECHOCARDIOGRAPHIC COMPLICATIONS OF DILATED CARDIOMYOPATHY AT A TERTIARY CARE HOSPITAL
AbstractBackground: Dilated cardiomyopathy can lead to a variety of complications recognisable onclinical, echocardiographic, electrocardiographic and radiographic assessment. Among this,transthoracic echocardiography has the dual advantage of being helpful in making the diagnosis ofdilated cardiomyopathy as well as an effective tool in early recognition of certain complicationsfor timely management to improve the quality of life of these patients. Methods: This descriptive(case series) study was undertaken at Departments of Medicine, Cardiology, Paediatrics andObs/Gyn, Ayub Teaching Hospital, Abbottabad from July to December, 2008. Fifty patients ofdilated cardiomyopathy without age and gender discrimination were selected by conveniencesampling. Those with hypertrophic and restrictive cardiomyopathies, valvular and congenital heartdisease, hypertension and ischemic heart disease were excluded. Results: Mean age was47.12±17.9 year with male predominance (males=34, females=16). Mean ejection fraction was30.6±6.9%. Complications revealed on echocardiography were intracardiac thrombi (5, 10%),spontaneous echo contrast (5, 10%), pericardial effusion (6, 12%), mitral regurgitation (46, 92%),tricuspid (25, 50%), aortic (5, 10%), pulmonary (2, 4%) multi-valvular regurgitation (28, 56%),and left atrial dilatation (36, 72%). Conclusion: LV systolic dysfunction, cardiac thrombi,spontaneous echo contrast, mitral and tricuspid regurgitation and left atrial enlargement areimportant complications of dilated cardiomyopathy. Echocardiography is important tool towardsidentification of these complications.Keywords: cardiomyopathy, dilated, cardiomyopathy, complications, cardiomyopathy,congestive, echocardiography
