Abstract Introduction: We sought to investigate whether the development of sub-pulmonic systolic anterior motion (SAM) may be inherent to the anatomy of the the mitral valve (MV) or affected by external factors, such as a dilated right ventricle or chest abnormalities in d-looped transposition of the great arteries post atrial switch operation (d-TGA/AtS). Methods: Analysis was performed of clinical and cardiac imaging studies acquired on 19 adult patients with d-TGA/AtS (age 42 ± 6 years old, 56% male) between 2015–2019. Echocardiography data included mitral apparatus anatomy, and CT/MRI data included biventricular dimensions, function, and Haller index… More >

Abstract Background: Pulmonary hypertension (PH) is one of the complications that can occur after the atrial switch procedure for transposition of the great arteries (TGA). This study aimed to assess the characteristics and prognosis of late-onset PH after the atrial switch procedure using catheterization data. Methods and Results: We retrospectively identified 40 patients with TGA after the atrial switch procedure that underwent catheterization between April 2007 and March 2020. Eligible patients were divided into two groups based on PH presence (PH group, n = 13 [33%]; non-PH group, n = 27 [67%]). Adverse events were defined as cardiac… More >
