Its spectrum varies from partial to transitional, or intermediate forms with a common AV valve and 2 orifices, or even the complete form. <b>Aim:</b> The aim of this study is to present a case of a woman in the fifth decade of life with Down syndrome and a transitional AVSD, diagnosed with echocardiography. <b>Case presentation:</b> This is a patient in the fifth decade of life with Down syndrome, transitional AVSD, and severe pulmonary hypertension. Her vital signs were normal, oxygen saturation of 89% on room air. Auscultation revealed pronounced pulmonary component of the second heart sound, diastolic murmur in se<span "="">cond left intercostal space, and moderate holosystolic heart murmur that radiated to axilla. The diagnosis was made with a transthoracic echocardiogram. The patient is receiving only medical treatment and since her last consult she has New York Heart Association (NYHA) functional class II. <b>Conclusion:</b> This case demonstrates the natural history of a patient in her fifth decade of life with down syndrome and complex congenital heart disease, despite having received only medical treatment, she is in functional class II. Echocardiography is the noninvasive technique of choice in the diagnosis and follow-up of patients with congenital heart diseases, as seen in this case.</span> </div>展开更多

To evaluate the value of two dimensional echocardiographic (2DE) technique devised specifically for morpholagical diagnosis, the results of 2DE,angiocardiography and surgery were examined retrospectively in 87 children with AVSD.Age ranged from 3 months to 11 years old (mean 3.9 years). 46 had partial AVSD, 12 had transitional AVSD, 29 had complete AVSD (type A in 21, type B in 4, type C in 4).2DE diagnosis is concordant with surgical diagnosis in 36/37 (97%) patients with partial AVSD, in 25/31 (84%) patients with transitional or complete AVSD. Most discordant diagnosis between 2DE and surgery occurred in patients with transitional or type A AVSD.The 2DE technique for morphological diagnosis of A VSD is superior to angiocardiography.The results indicated that morphological manifestations of AVSD could be clearly demonstrated with the use of apical and subxiphoid 2D imaging planes, reliable morphological diagnosis could be obtained.展开更多

He had been perfectly well until he was brought to the emergency room because of acute heart failure. Chest radiography revealed right-side heart enlargement. Electrocardiography indicated atrial flutter. Echocardiography revealed a large ostium primum atrial septal defect and moderate mitral regurgitation. The pulmonary-to-systemic blood flow ratio was 3.24. First, cardiologists performed catheter ablation of the cavotricuspid isthmus for atrial flutter. We performed patch closure of an ostium primum atrial septal defect and mitral valve repair after the patient’s heart failure was under control. The patient was discharged 13 days postoperatively in a satisfactory condition without any critical complications.展开更多
