Total surgical repair of tetralogy of Fallot is usually associated with a favourable long-term outcome. However, complications or consequences of the defect such as dilatation of aortic root and aortic regurgitation are present in some patients. ⋯ 1. Minor aortic regurgitation and LV dilatation are present in 20% of adults who underwent repair of tetralogy of Fallot. 2. Aortic regurgitation is present in those who have dilated aortic root. 3. Aortic regurgitation is not associated with palliative surgery performed in the past. 4. Aortic regurgitation is more frequent in the elderly but is not associated with patient's age at surgery or time elapsed since repair.

In spite of surgical correction, arterial hypertension may persist in a significant proportion of patients with aortic coarctation. ⋯ 1. Hypertension is present in more than half of adult patients after surgical repair of aortic coarctation, is more frequent in patients who underwent surgery at a more advanced age, and in the majority of patients is not associated with the presence of residual trans-aortic gradient. 2. LV thickness, mass and index increase due to hypertension, regardless of the presence of gradient. 3. LV diastolic parameters are similar to those in healthy subjects, however, they become impaired as the time from surgery increases, particularly in patients who underwent repair at an advanced age and who have hypertension.

Factors determining long-term maintenance of sinus rhythm after cardioversion of persistent atrial fibrillation.
Long-term maintenance of sinus rhythm (SR) after successful cardioversion (CV) of persistent atrial fibrillation (AF) carries a low risk of stroke and may avoid the risks associated with anticoagulation. ⋯ Left atrial area and left ventricular fractional shortening are the independent predictors of the maintenance of SR after successful CV in patients with persistent AF.
