A 71-year-old female presents with central chest pain and shortness of breath and further investigation reveals marked dilatation of the thoracic aorta. Computed tomography of the aorta (CTA) demonstrates a maximal diameter of the aortic root of 40 mm, ascending aorta of 70 mm, aortic arch of 57 mm and the descending thoracic aorta of 40 mm. Transthoracic echocardiogram demonstrates a dilated left ventricle with severe global systolic dysfunction. The left ventricular ejection fraction is 33%. There is moderate aortic regurgitation and moderate mitral regurgitation. Coronary angiography reveals no significant coronary disease. Medical history includes hypertension, chronic bronchitis and current cigarette smoking. The patient is functionally independent with an exercise tolerance of up to 5 km walking on flat ground. She is consented to undergo a first stage aortic valve replacement, mitral valve repair or replacement, replacement of the ascending aorta and aortic arch using the branch-first technique and frozen elephant trunk (FET). A thoracic endovascular aortic repair (TEVAR) is planned for the second stage.
