Coexisting idiopathic hypertrophic subaortic stenosis and coronary artery disease. Clinical implication and operative management.
Patients with either coronary artery disease (CAD) or idiopathic hypertrophic subaortic stenosis (IHSS) may have angina as a dominant symptom. It is also possible that these two diseases may coexist in the same patient. Such an association has been reported in 25% of patients with IHSS who are over 45 years of age. It is important that both entities be looked for in the evaluation of the patient with angina, particularly when operative management is contemplated. Treatment of one and not the other may leave the patient symptomatic. We have encountered three patients with both CAD and severe IHSS and have managed each with septal myectomy and coronary artery revascularization. Each has obtained significant symptomatic improvement.
