Fragmented QRS complex (fQRS) on 12-lead ECG, a marker of myocardial scar, is predictor arrhythmic events in patients with ischemic and nonischemic cardiomyopathy. We investigated whether the presence fQRS associated severity anomaly increased adult Ebstein (EA).In 51 consecutive EA (median age, 37 years; 18 males), index calculated from echocardiographic data clinical were analyzed. The extent each patient was measured by counting number ECG leads showing fQRS. There 35 (68.6%) (fQRS group)...
Percutaneous device occlusion of secundum atrial septal defect (ASD) has become an accepted alternative to surgical repair. A variety devices have been used successfully. However, all them limitations. We report our experience with two close multiple ASDs.
The objectives of this study were to assess the clinical outcomes adults with Ebstein Anomaly (EA) according their treatment modalities. All adult EA patients diagnosed between October 1994 and 2014 retrospectively evaluated by medical record review. Total 60 categorized into 3 groups strategy, i.e. non-operative (Group I, n = 23), immediate operative II, 27), delayed III, 10). A composite major adverse cardiac cerebrovascular events (MACCE) factors associated MACCE assessed in each group....
Atrial tachyarrhythmia is a well-known long-term complication of atrial septal defect (ASD) in adults, even after successful trans-catheter closure. However, the risk factors for early-onset closure remain unclear. This retrospective study enrolled adults with secundum ASD undergoing from January 2000 to March 2014. We analyzed clinical characteristics patients and assessed new-onset defined as composite fibrillation or flutter (AF/AFL) total 427 patients; 123 were male (28.8%) median age...
For the successful completion of transcatheter closure atrial septal defects with Amplatzer occluder, shape should be considered prior to selecting device. The purpose this study is evaluate results a oval shaped defect.From November 2009 until 2011, cardiac computed tomography was performed on 69 patients who needed defect. We defined an defect as ratio shortest diameter longest ≤ 0.75 measured using tomography. A trans-thoracic echocardiogram one day after and six months after.The...
Background and Objectives:The aim of this study was to investigate the balloon occlusive diameter (BOD) non-circular defects in transcatheter closure atrial septal defect (ASD).Subjects Methods: A total 67 patients who had undergone an ASD were reviewed retrospectively.A noncircular defined as ratio short long on en-face image less than 0.75.The BOD compared with then between two groups.Results: There 22 circular 45 defects.The difference measuring from quite different groups significantly...
Recently, minimally invasive surgical (MIS) techniques including robot-assisted operations have been widely applied in cardiac surgery. The thoracoscopic technique is a favorable MIS option for patients with atrial septal defects (ASDs). Accordingly, we report the mid-term results of ASD closure without robotic assistance.We included 66 who underwent between June 2006 and July 2014. Mean age was 27±9 years. mean size 25.9±6.3 mm. Eleven (16.7%) had greater than mild tricuspid regurgitation...
<strong>Background:</strong> Acute changes in left ventricular diastolic function shortly after ASD closure elderly patients have not been well known. We aimed to investigate acute end pressure (LVEDP) following transcatheter of atrial septal defect (ASD). <br /><strong>Methods:</strong> All 19 adults with ASDs who underwent between June 2013 and December 2014 were enrolled. LVEDP was measured prior device compared that immediately 15 minutes closure....
<b><i>Objectives:</i></b> It was our aim to evaluate whether the defect area plays a crucial role in successful device closure of atrial septal defects (ASDs). <b><i>Methods:</i></b> The long and short diameters were measured on en-face images. then by planimetry. size compared length analyzed each group. <b><i>Results:</i></b> There 22 patients circular group 45 noncircular did not differ between groups (201.6 ± 107.1...
Purpose We purposed to determine the outcomes of surgical mitral valve repair in patients with atrial septal defect(ASD) and mitralregurgitation (MR) factors associated good outcomes. Methods Sixty-one after operation for ASD MR were enrolled. Mitral annular diameter, lengths leaflets, motion angles both leaflets measured on echocardiographic images. Results The severity prolapse improved surgery from 2.3± 0.7 1.7±0.9 41.8% 16.4%,respectively. In postoperative grade <3, systole posterior...
<p><b>Background:</b> For successful transcatheter closure of an atrial septal defect with the Amplatzer occluder, shape should be considered before selecting device size. The purpose this study was to evaluate results ovoid defect.</p><p><b>Methods:</b> Between January 2010 and February 2012, cardiac computer tomography examinations were performed in 78 patients who subsequently underwent defect. In retrospective study, we reviewed these patients'...
Background: Atrial septal defect (ASD) can be closed safely by transcatheter closure with an Amplatzer occluder (ASO) cardiac computed tomography (CT) being used to image and evaluate the ASD. The purpose of this study was characteristics Secundum ASD CT determine whether is alternative balloon sizing. Methods Results: Forty-four cases were evaluated CT. we measured diameters lengths rims. patients divided into two groups: not using a sizing technique (group 1), 2). Most showed ellipsoid...
