Section snippets
Case 1
An 87-year-old fragile woman diagnosed with severe AS, with multiple hospitalizations due to heart failure and worsening in her functional class was referred to the heart team for TAVI. Baseline echocardiogram revealed a normal biventricular function, severe AS, moderate MR and mild TR with an estimated systolic pulmonary artery pressure of 50 mm Hg. Coronary angiogram showed a left coronary dominance without significant stenosis (Fig. 1A,B). Intraprocedural transesophageal echocardiography
Case 2
A 92-year-old woman diagnosed with severe symptomatic AS was accepted for transfemoral TAVI because of her age and high surgical risk (STS 10.1%). Pre-procedural imaging studies showed a normal biventricular function with no abnormalities in the segmental contractility, mild MR and no coronary lesions. The left and right heights were 13 and 11 mm respectively, with an aortic sinus diameter of 33 mm by cardiac CT scan.
A 26 mm Corevalve Evolut-R was implanted in an adequate position. During

2018, Cardiovascular Revascularization MedicineCitation Excerpt :Primary analysis of the data was performed using descriptive statistics such as mean and standard deviations, frequencies and percentage frequency distributions using Microsoft Excel 2013, version 15.0.4875.1000 (Microsoft, Redmond, Washington) for analysis. A total of 40 publications describing 86 patients with native and 10 patients with bioprosthetic aortic valve stenoses were identified [12,13,17–54]. The baseline characteristics are summarized in Tables 1 and 2.
