A combined transradial, transfemoral and subclavian approach in the treatment of hypertrophic obstructive cardiomyopathy with alcohol septal ablation
Abstract
Introduction: Alcohol septal ablation (ASA) is together with septal myectomy respected method of treatment in patients with hypertrophic obstructive cardiomyopathy. There are only scarce experiences using transradial approach in ASA.
Purpose of the study: To evaluate acute and mid-term results of ASA performed transradialy. Methods: ASA was performed from the right radial artery, pacemaker lead was inserted using subclavian approach, the left ventricle pressure was measured by pigtail catheter inserted transfemoraly.
Actual changes in ultrasonography and catetherization parameters as well as changes in clinical status were observed and the patients were followed-up at out-patient department. Conclusions: ASA performed transradialy is effective and safe method of treatment in patients with HOCMP.
Significant reduction of gradient, pulmonary pressure, symptoms and degree of mitral insufficiency were seen after this procedure. After 3 months the thick -ness of IVS and EF significantly decreased.
There were no changes in thickness of PW and diameter of LA during mid-term follow-up and a positive clinical effect lasted in all patients.
