Multi-hole Atrial Septal Defect: A diagnostic and therapeutic challenge (original) (raw)
2020, Clinical Research and Trials
Atrial Septal Defect (ASD) is the third most common congenital heart defect. There are three main types of ASD: ostium secundum, ostium primum and sinus venous. There are few reports of multi-hole ostium secundum ASD, its incidence is estimated in 4-10%. A 56-year-old male attends to medical consultation due to three-month exertional dyspnea, palpitations and lower limb edema. Transthoracic echocardiogram reported dilatation of right cavities, ostium secundum ASD, severe tricuspid insufficiency, pulmonary hypertension, left ventricular ejection fraction of 60%. A cardiac examination with arrhythmic heart sounds, splitting of the second sound and systolic murmur in second right intercostal space. Electrocardiogram showed atrial fibrillation and incomplete right bundle branch block. The 2D and 3D transesophageal echocardiogram confirmed the presence of multi-hole ostium secundum ASD. Right heart catheterization showed mild pulmonary hypertension. Surgical management was suggested to correct the multi-hole ASD. The diagnosis of the ASD should always include a 3D transesophageal echocardiogram for a detailed assessment of the interatrial septum. Complex multi-hole ostium secundum ASD is a relative contraindication for closure with an Amplatzer device; therefore, a surgical treatment with opened exposure should be done.

Case report A 79-year-old patient with secundum type atrial septal defect
termedia.pl
Atrial septal defect (ASD) is a congenital heart lesion that enables blood passage between the left and right atria through the interatrial septum. It occurs in 1/1500 births. Atrial septal defects constitute 6-10% of all congenital heart lesions. They can be investigated as ostium ...

The purpose of this paper is to review the usefulness of multiplanar transesophageal echocardiography before, during and after percutaneous transcatheter closure of secundum atrial septal defects. Transesophageal echocardiography imaging techniques,including their role in patient selection, procedural guidance and immediate assessment of technical success and complications are described and discussed in this review. Percutaneous transcatheter closure is indicated for ostium secundum atrial septal defects of less than 40 mm in maximal diameter. The defect must have a favorable anatomy, with adequate rims of at least 5 mm to anchor the prosthesis. Transesophageal echocardiography plays a critical role before the procedure in identifying potential candidates for percutaneous closure and to exclude those with unfavorable anatomy or associated lesions, which could not be addressed percutaneously. Transesophageal echocardiography is also important during the procedure to guide the deploym...
Uncommon Facades of Atrial Septal Defect -A Case Series
https://www.ijrrjournal.com/IJRR\_Vol.7\_Issue.11\_Nov2020/Abstract\_IJRR0026.html, 2020
Atrial septal defect (ASD) is one of the most common congenital cardiac lesions in adults. While the most common symptoms include fatigue, exertional dyspnea, and palpitations, the presentation of ASD can be protean. In this article, we describe three uncommon presentations of ostium secundum ASD. Patient 1 presented with pericardial tamponade. Patient 2 presented with ventricular tachycardia. Patient 3 had moderately severe mitral regurgitation. These patients had chest radiographs and electrocardiograms typical of secundum ASD, but their presentations were atypical.

Background: Atrial septal defect (ASD) is often an isolated disease, but its association with other abnormalities can make diagnosis challenging. Careful analysis of simple complementary exams can help precise anatomical diagnosis ensuring suitable treatment. The aim of this article is to report, from a case report and literature review, diagnostic challenges and the contribution of simple complementary exams, such as chest X-ray, for the diagnostic orientation of an ASD associated with peripheral pulmonary artery stenosis, as well as therapeutic particularities. Case report: We report the case of a girl born in 2007, with history of dyspnoea and recurrent bronchitis in whom a loud systolic murmur was detected fortuitously at the age of 2 years. Her clinical examination was otherwise normal. The electrocardiogram recorded sinus rhythm, incomplete right bundle branch block, and right ventricular hypertrophy. Chest X-ray showed moderate cardiomegaly and hypervascularity of the left lu...
Case Report Typical signs of secundum atrial septal defect in a young female
We report the case of a 25-year-female presented with dyspnea & chest pain on exertion. The ECG showed signs of right ventricular overload. The chest X-ray showed an enlargement of central pulmonary arteries, pulmonary plethora and a small aortic knuckle. Atrial septal defect (ASD) was suspected and transthoracic echocardiography (TTE) subsequently confirmed the presence of a large ostium secundum ASD. A surgical closure with an equine pericardium patch was performed. Two months after the surgical repair, the ECG and TTE showed the regression of signs of right ventricular overload.
Transcatheter Device Closure of Secundum Atrial Septal Defect in Adult Patient
Acta Informatica Medica, 2021
Background: Atrial septal abnormalities are common congenital lesions remaining asymptomatic until adulthood in a great number of patients. The most frequent atrial septal defects in adults are ostium secundum atrial septal defect (ASD). Complications from untreated, hemodynamically significant ASD are atrial arrhythmia, paradoxical embolization, Eisenmenger's syndrome, pulmonary hypertension, and right ventricular failure. Objective: We present a case report of secundum ASD in adult female patient who underwent transcatheter device closure with Amplatzer occluder. Methods and Results: The case of female Bosnian patient 50 years old who lives in Belgium for 20 years ago and during her visit to Bosnia she came to our polyclinic for cardiological exam. Echocardiographic exam showed enlargement of left atrium (LAD 51mm), right atrium and ventricle (RAD 46mm, RVd 33mm), atrial septal defect 9mm with left right shunt Qp:Qs 2,3:1. Several months later transcatheter device closure with Amplatzer occluder was performed and subsequent symptomatic improvement reported after closure. Conclusion: Echocardiography has superior role for precise evaluation of ASD type secundum who are suitable for transcatheter device closure as primary treatment option. Transcatheter techniques has now become preferable to surgical repair and provide valid option of treatment for this type of CHD.
The ampatzer septal occluder as a standard for therapy of secudum-type atrial septal defect
The Journal of the Louisiana State Medical Society, 2004
Atrial septal defect (ASD) accounts for 5-10% of congenital heart malformations. An uncorrected ASD may lead to congestive heart failure, severe pulmonary hypertension, or paradoxical arterial embolism with stroke. Transthoracic echocardiography is often diagnostic in the pediatric population, but transesophageal echocardiography may be required in adults. Closure of an ASD traditionally has been performed surgically, but the most common type (secundum ASD) can now be closed with a percutaneously deployed device. We briefly describe the types of ASDs and their diagnosis. Results of percutaneous closure in 74 children and adults are then presented.
