Coronary computed tomography angiography (CTA) showed diffuse stenosis in the left anterior descending and the first diagonal branch arteries. Electrocardiogram (ECG) might not always show abnormalities, and chest pain is not always present. His headache improved after percutaneous coronary intervention.

The attending provider wrote “Agree with electrocardiogram interpretation”. The red arrow shows a roughly 80% stenosis of the proximal LAD. The blue arrow shows another stenosis of the LAD distal to the first diagonal branch of about 99%. The green arrow shows a 95% stenosis of the ostium of the first diagonal branch.

Aims The majority of patients with severe aortic stenosis (AS) planned for transcatheter aortic valve implantation (TAVI) are elective outpatients. TIM will include a daily assessment of weight, blood pressure, a 2-channel electrocardiogram, peripheral capillary oxygen saturation, and a self-rated health status until admission for TAVI.

Laboratory tests showed markedly elevated troponin I levels (>50 ng/ml) and atrial fibrillation, along with inferior wall ST elevation on the electrocardiogram. A 2D echocardiogram revealed an ejection fraction of 43%, hypokinesia of the anterior and intraventricular septum from base to apex, and severe mitral stenosis.
