Alcohol septal ablation in a young patient after aortic valve replacement.
A 38-year-old male presented with heart failure symptoms and was diagnosed with aortic valve endocarditis and underlying aortic stenosis in the absence of concentric hypertrophy or bicuspid aortic valve and underwent aortic valve replacement but continued to have symptoms which were then attributed to hypertrophic cardiomyopathy with dynamic left ventricular outflow tract obstruction. He was determined to be unsuitable for myomectomy and underwent successful alcohol septal ablation using transthoracic echocardiographic Doppler and continuous wave velocity monitoring without requiring to cross the aortic valve or to perform transatrial septostomy and left ventricular pressure monitoring. When crossing the aortic valve is a relative or absolute contraindication like in our index case, continuous Doppler velocity recording is a safe and effective alternative approach to monitor the outflow gradient while performing alcohol septal ablation.
