Increasingly patients are surviving after reconstructive surgery of the ascending aorta. These patients require follow-up to detect postoperative prognostic markers, such as persistence of the flow in a false lumen, intimal rupture, or graft complications. We conducted a study with transthoracic and transesophageal echocardiography in order to detect residual abnormalities and establish the usefulness of this technique in a group of patients after Bono-Bentall surgery for ascending aorta pathology. ⋯ In patients undergoing surgery with the Bono-Bentall procedure there is a high incidence of residual aortic abnormalities, especially when the operation is for aortic dissection. Transesophageal echocardiography is an ideal diagnostic method for the detection and follow up of residual abnormalities after ascending aorta surgery. We believe this technique should be included in the periodic follow up of these patients.

Comparative Study
[Appraisal of the state of the autonomic nervous system in hypertrophic cardiomyopathy by the analysis of heart rate variability].
The analysis of heart rate variability has been accepted as a non-invasive method to evaluate the influence of the autonomic nervous system over the heart. Although heart rate variability has been used during the last decade in several illnesses the studies in hypertrophic cardiomyopathy are scarce. ⋯ These facts suggest that the patients with hypertrophic cardiomyopathy have an alteration in the autonomic nervous system: sympathetic (low spectral frequencies) and parasympathetic activity (high spectral frequencies), although this does not reflect an imbalance between sympathetic and parasympathetic activities (relation of low to high spectral frequencies).
