Insights
This case report details a rare instance of obstructive hypertrophic cardiomyopathy co-occurring with a coronary artery fistula in a 60-year-old man. Beta-blocker therapy effectively managed his exertional angina, leading to a favorable clinical outcome.
Area of Science:
- Cardiology
- Cardiovascular Medicine
- Clinical Case Reports
Background:
- Obstructive hypertrophic cardiomyopathy is a significant cardiac condition.
- Coronary artery fistulas are uncommon vascular anomalies.
- The co-occurrence of these two conditions is exceptionally rare.
Abstract:
We report a case of a 60-year-old man with a history of angina on exertion (New York Heart Association Class II) who was found to have mid-cavitary obstructive hypertrophic cardiomyopathy on two-dimensional echocardiography and whose coronary angiogram showed right coronary artery-left ventricular fistula, with no significant coronary atherosclerosis suggestive of ischaemic heart disease. The patient was started on beta-blocker therapy, and on follow-up his angina improved. The patient had a benign course and did not have any progressive heart failure or acute coronary syndrome on follow-up. This case report highlights a rare association of mid-cavitary obstructive hypertrophic cardiomyopathy with coronary artery fistula.
