This study reports our medium term follow up of perimembranous and muscular ventricular septal defects with tunnel shape aneurysm closure using the Amplatzer duct occluder. Materials and Methods: From May 2006-December 2012, we used Amplatzer duct occluder in seven ventricular septal defect patients here atHamad General Hospital,Doha,Qatar. There were 4 male and 3 female patients with an age range of 4 - 32 years with a median of 8 years and weight range of 16 - 63 kgwith a median of33 kg. In this group, 6 were perimembranous and 1 muscular and all these ventricular septal defects had a tunnel shape aneurysm. Transesophageal echocardiographic diameter ranged from 4 - 8 mmand Qp/Qs was 1 - 1.6. Angiographically, the diameter on the left ventricular side measured 3.5 - 10 mmand on right ventricular side 2.4?- 5 mm. 8/6 mmAmplatzer duct occluder was used to close these ventricular septal defects. Results: There were no major complications and immediately after the procedure there was no residual shunt in any of these patients and all the patients remained in normal sinus rhythm. One patient was expatriate and no further follow up was available. The rest of the 6 patients had 1 - 80 months with a median of 54 months follow up and none of these patients had any residual shunt and all remained in normal sinus rhythm. Two patients developed trivial aortic valve regurgitation immediate post procedure, one remained unchanged and the 2nd has progressed to mild at this latest follow up. Conclusion: Amplatzer duct occluder is feasible and a safe device for percutaneous closure of selective tunnel shape aneurysmal perimembranous and muscular ventricular septal defects.展开更多

In this study, we present all the ALCAPA patients which were admitted at our institution during April 2007-December 2010. Retrospective review of these patients regarding their clinical presentation and the use of diagnostic modalities will be presented in this series. There were total of five patients, three male and 2 female, with age range of 2 - 12 months. The most common symptoms at presentation were tachypnea (4/5) and poor feeding with irritability (3/5). Electrocardiogram was abnormal in 2/5 cases and chest X ray revealed cardiome-galy with pulmonary congestion in 4/5 patients. Echocardiogram showed mitral valve regurgitation in 5/5 cases (3 with moderate and 2 with mild to moderate), Left ventricular dilatation/dysfunction in 4/5 patients, echogenic left ventricular papillary muscles in 4/5 patients and prominent right coronary with strong suspecision of ALCAPA in 4/5 patients. Coronary angiography was performed in 4/5 cases to confirm the diagnosis. We conclude that by thorough clinical assessment along with ECG and CXR, the diagnosis of ALCAPA can be strongly suspected. Echocardiogram can almost always make the diagnosis of ALCAPA and coronary angiography can confirm the diagnosis in rare atypical cases.展开更多
