<p><b>Background:</b> Severe congenital aortic stenosis in infants is a life-threatening congenital heart anomaly that is typically treated using percutaneous balloon aortic valvuloplasty.</p><p><b>Methods:</b> The usual route is the femoral artery under radiographic guidance. However, this procedure may be limited by the small size of the femoral artery in low-weight infants. An infant weighing only 7 kg with severe aortic stenosis (peak gradient was 103 mmHg) was successfully treated with a novel approach, that is trans-ascending aorta balloon aortic valvuloplasty guided by transesophageal echocardiography.</p><p><b>Results:</b> The patient tolerated the procedure well, and no major complications developed. After the intervention, transesophageal echocardiography indicated a significant reduction of the aortic valvular peak gradient from 103 mmHg to 22 mmHg, no aortic regurgitation was found. Eighteen months after the intervention, echocardiography revealed that the aortic valvular peak gradient had increased to 38 mmHg and that still no aortic regurgitation had occurred.</p><p><b>Conclusions:</b> In our limited experience, trans-ascending aorta balloon aortic valvuloplasty for severe aortic stenosis under transesophageal echocardiography guidance effectively reduces the aortic peak gradient. As this is a new procedure, long-term follow up and management will need to be established. It may be an alternative technique to treat congenital aortic stenosis in low-weight patients.</p>

Background and aim of the study: Mitral repair is now as the treatement of choice in patients suffering mitral regurgitation due to mitral valve prolapse or flail. However, mitral valve repair demands the mitral valve morphology being feasible for repair. The study aims at evaluating transthoracic and transesophageal echocardiographic features in consecutive patients with mitral valve prolapse or flail undergoing surgical repair at Hue Central Hospital. The correlation between preoperative and intraoperative echocardiographic features and surgical findings in these patients. These echocardiographic data may predict the surgical outcome. Methods: From December 2010 to January 2013, 73 patients (37 men, 36 women; average age 37.5) were recruited into the study. All patients had degenerative mitral valve disease causing important regurgitation and underwent systematic preoperative transthoracic echocardiography, preoperative and intraoperative transesophageal echocardiography for delineation of six segments (scallops) of anterior and posterior leaflets. Results: Among 73 patients, 64 patients were in fibroelastic deficiency (87.7%) and 9 patients suffered Barlow disease (12.3%). Mitral valve repair was performed in 52 patients (71.2%) and mitral replacement was performed in 21 patients (28.8%). All 52 mitral valve repair (81.3%) and 12 mitral valve replacement (18.7%) was performed in fibroelastic deficiency patients. All 9 Barlow patients must undergo mitral valve replacement (100%). A prolapse or flail of mitral valve in 73 patients was documented by transthoracic and transesophageal echocardiography and confirmed on surgical inspection. Accuracy of transthoracic echocardiography was (89.0%) and accuracy of transesophageal echocardiography was (91.8%) in identifying mitral valve segments prolapse or flail. Success rate of mitral valve repair was (98.0%) in prolapse of 1 or 2 segments, but was low (36.0%) in prolapse > 3 segments. Success rate of mitral valve repair was (96.6%) in prolapse of posterior leaflet, but was (63.6%) in prolapse anterior leaflet or bileaflet. Conclusion: - Mitral valve repair was favorable in fibroelastic deficiency patients, but difficult in Barlow patients. - Accuracy of transthoracic and transesophageal echocardiography was high in identifying mitral valve segments prolapse or flail. - Success rate of mitral valve repair was high in prolapse of 1 or 2 segments. - Success rate of mitral valve repair was high in in prolapse of posterior leaflet.

Introduction: The prevalence and significance of thoracic aorta atherosclerosis in AF patients has not been clearly defined in the literature. There are scant reports supporting an association of atherosclerotic aortic plaque burden with embolic phenomena and recurrence of AF post ablation. Two modalities of aortic atherosclerosis detection include computed tomography (CT) and echocardiography. Hypothesis: The prevalence of ascending aorta atherosclerosis in AF patients is high and CT performs better than transthoracic echocardiography in its detection. Methods: We investigated prevalence of ascending aorta atherosclerosis by CT and transthoracic echocardiography in 76 consecutive patients referred for AF ablation (67.1% males, 62.9 +/- 9.8 years old, 6.6% active smokers, 75% paroxysmal AF, 13.1% with LV ejection fraction (EF) <50%, 61.8% with hyperlipidemia, 55.8% with hypertension, 10.5% with diabetes, 2.6% with chronic kidney disease, and 1 patient with peripheral artery disease). The pre-ablation echocardiograms and cardiac CT scans, originally performed for left atrial mapping and evaluation of left atrial appendage thrombus, were reviewed in a blinded fashion for the presence of aortic atherosclerosis. Results: Out of 76 AF ablation patients, 27 (35.5%) had evidence of ascending aorta atherosclerosis by CT and 43 (56.6%) by echocardiography. Using CT as the gold standard, echocardiography had a sensitivity of 70.4% and a specificity of 51% in identification of ascending aorta atherosclerosis. Positive and negative predictive values were 44.2% and 75.8%, respectively. A total of 16 patients (21.1%) had AF recurrence post ablation, out of which 6 (37.5%) had evidence of aortic atherosclerosis on CT (vs 21/49 [42.9%] in the non-recurrence group). Conclusions: Ascending aorta atherosclerosis is common in patients referred for AF ablation. Transthoracic echocardiography likely overestimates its prevalence. Aortic atherosclerosis as detected by CT was not significantly associated with AF recurrence post ablation. More studies investigating clinical implications and best treatment approach to subclinical aortic therosclerosis in patients with AF are needed.
