ABSTRACT
INTRODUCTION: Atrial septal defects (ASD) constitute the most frequent congenital heart disease in adults and ostium secundum (OS) the most common type. Benefit of its closure in adulthood has long been controversial. AIM: To evaluate outcomes of OS-ASD closure in adults. METHODS: Retrospective cohort study, over a ten-year period from 2008 to 2018. All adults (≥20 years old) who benefited from OS-ASD closure were included. Study endpoints were closure success rate, functional status evolution and incidence of new arrhythmias at 12 months. RESULTS: Fifty patients were recruited. Dyspnea (≥ NYHA II) was noted in 58% and arrhythmia in 18% of patients. Feasibility of a percutaneous closure was 50%. Closure success rate was 100%. Surgery was associated with high postoperative morbidity with longer hospitalization stay (20 vs. 4 days, p <0.001). At 12 months, an improvement in functional status was observed in 79%. Incidence of new arrhythmias was 5%. A significant decrease in right cavities dilation as well as pulmonary arterial pressure has been reported. CONCLUSIONS: Immediate results of OS-ASD closure in adults are satisfactory. Percutaneous closure is associated with reduced hospital morbidity. At 12 months, a significant improvement in functional status was observed however the possible occurrence of new arrhythmias imposes a close follow-up.

BACKGROUND: Konno procedure is used to enlarge the aortic root and increase the size of the aortic valve implanted. AIM: The aim of this study is to present the indications of the Konno procedure in congenital and acquired aortic lesions, in young patients with normal or hypoplastic aortic annulus or adults with small aortic annulus. METHODS: We reported our experience of this technique with a retrospective study of 13 patients operated on between 1998 and 2004. RESULTS: The mean diameter of aortic annulus measured in echocardiography is 16.2 mm, and the mean prosthetic valve diameter in post operative control is 20.3 mm. The early Death rate was 16%. In the late follow up of 2 years, the only predictor of myocardial hypertrophy regression was the presence of aortic insufficiency before the operation. In the literature, Konno procedure is reported as a good surgical option for the enlargement of the left ventricular outflow tract, but the results with the Ross-Konno operation are more promising.
