Background: Secundum atrial septal defect (ASD) is treated following trans-catheter closure in alternative to surgical treatment. Per-intervention selection of device size with balloon occlusive diameter (BOD) often cause tearing or enlarging, causing arrhythmias and hypotension. We assessed the suitability of percutaneous device closure for ASD using 3-dimensional transthoracic echocardiography (3DTTE).
Objectives: This study was conducted to investigate if 3DTTE could be an alternative of balloon sizing for selection of device size in atrial septal defect device closure.
Design: It was a cross-sectional comparative study.
Methods: This study was conducted at the department of Pediatric Cardiology, Bangabandhu Sheikh Mujib Medical University for a period of 2 years. Thirty-three purposively selected secundum ASD patients suitable for device closure were included in the study. Ethical permission was taken from the Institutional Review Board and written consent was taken from each patient's guardian. In this study, 3DTTE derived ASD diameter and BOD were compared with that of deployed device size using correlation analysis.
Results: Out of 33 patients, 63.6% were female and 36.4% were males had a mean age of 18.07 ± 14.58 years (range 2-55 years). Mean diameter of ASD measured by 2-dimensional (2D) and 3-dimensional (3D) echocardiography were 17.09 ± 6.08 mm and 21.30 ± 6.56 mm, respectively, yielding a significant difference ( < 0.001). 3D echocardiography derived ASDs diameter were highly correlated with device size than BOD and 2D echocardiography derived diameter (2D echocardiography: = 0.796, = <0.001, 3D echocardiography: = 0.960, = <0.001, BOD: = 0.840, = <0.001).
Conclusion: 3DTTE can accurately measure ASD diameter and can be used as an alternate, effective, and safe method to select device size.

Patients with secundum atrial septal defects preferentially undergo device closure; however, this procedure is not always feasible. Instead, patients can safely undergo surgical closure. At a time when minimally invasive surgery can now be utilized with improved cosmetic results and the same excellent outcomes as a conventional sternotomy for an atrial septal defect closure, we propose the partial lower ministernotomy as the new standard for surgical atrial septal defect closure.

Background: Transthyretin cardiac amyloidosis (ATTRCA) is a prevalent disease, and it can be associated with heart failure (HF), left ventricle hypertrophy (LVH), atrial fibrillation (AF), and aortic stenosis (AS).
Aim: The study aims to detect the prevalence of ATTRCA in the symptomatic AS population.
Method: A single-center prospective study screening for ATTRCA in patients diagnosed with symptomatic severe AS undergoing aortic valve (AV) intervention.

Background: Cardiac sarcoidosis (CS) is a chronic inflammatory disease characterised by non-caseating granulomas, while arrhythmogenic cardiomyopathy (ACM) is a genetic condition mainly affecting desmosomal proteins. The coexistence of CS and genetic variants associated with ACM is not well understood, creating challenges in diagnosis and management. This study aimed to describe the clinical, imaging and genetic features of patients with both conditions.

Rationale: The transcatheter closure and atrioseptopexy are the main treatment methods for atrial septal defect (ASD). However, persistent hypoxemia due to iatrogenic diversion of inferior vena cava (IVC) to the left atrium (LA) is reported as a rare complication after ASD closure. Contrast echocardiology is a reliable and powerful tool to detect iatrogenic diversion and identify the etiology accurately.
