5. Atrial Septal Defect
ASD is the most common congenital heart disease encountered in adult.
ASD occurs in one child per 1,500 live births.
ASD is more common in female with ratio of 4:1 .

6. Types of ASDs There are 4 types of ASD Ostium Secundum. Ostium Primum.
Sinus Venosus.
Coronary sinus defects.

7. Secundum defects
Secundum defects are the most common, accounting for 6-10% of all congenital lesions.

8. Atrial Septal Defect (Primum)
Ostium primum is the next most common type and is located in the lower portion of the atrial septum.
This type of ASD often will have a mitral valve defect associated with it called a mitral valve cleft .

9. Atrial Septal Defect (Primum)

10. Sinus Venosus ASD
Partial anomalous pulmonary venous connection (right pulmonary veins to junction of superior vena cava and right atrium.

11. Sinus Venosus ASD
Sinus venosus ASD associated with PAPVR.

12. Sinus Venosus ASD
Routine chest X-ray of this 14 year old girl suggests prominent right heart borders on the two views. There is also prominence of the pulmonary artery segment due to pulmonary overcirculation from partial anomalous right pulmonary veins draining into the SVC and an associated atrial sinus venosus defect.

13. Sinus Venosus ASD
Routine chest X-ray of this 14 year old girl suggests prominent right heart borders on the two views. There is also prominence of the pulmonary artery segment due to pulmonary overcirculation from partial anomalous right pulmonary veins draining into the SVC and an associated atrial sinus venosus defect.

14. Cardiac Auscultation in ASD
Increased flow across the PV produces a systolic ejection murmur and fixed splitting of the second heart sound. Fixed splitting of S2 may in part be due to delayed right bundle conduction.
Increased flow across the TV produces a diastolic rumble at the mid to lower right sternal border.

15. CHEST X RAY IN ASD
The chest x-ray demonstrates prominent pulmonary vessels and a proximal pulmonary artery segment.

16. CHEST X RAY IN ASD
Chest x-ray of untreated ASD demonstrates prominent pulmonary vessels and a proximal pulmonary artery segment.

18. Role Of Echocardiography

19. ME 4 Chamber View
The ME 4C view (0°) is obtained by positioning the probe in the mid-esophagus behind the LA.
The imaging plane is directed thru the LA, center of the MV and apex of the LV.

20. ME 4 Chamber View
A snapshot of the heart is obtained that includes all 4 chambers (LA, RA, LV, RV), 2 valves (MV, TV),
The septums (IAS, IVS) and the inferoseptal and anterolateral LV walls.
Segments of the anterior (A2) and posterior (P2) mitral valve leaflets are typically imaged in this view.

Segments of the anterior (A2) and posterior (P2) mitral valve leaflets are typically imaged in this view. LA LV RV

22. ME 4 Chamber View Identify the Following Structures:- Left Atrium (LA)
Right Atrium (RA)
Left Ventricle (LV): inferoseptal (IS) + anterolateral (AL) walls

Mitral Valve: anterior(AMVL) + posterior (PMVL) leaflets
Tricuspid Valve: septal (STVL) + anterior (ATVL) leaflets

36. Amplatzer ASD closure device.

37. Indications for percutaneous closure of an ASD
The basic requirements for percutaneous closure of an ASD include:
Secundum defect.
Adequate inferior and superior rim around the defect. Therefore, device closure will not impinge upon the superior vena cava , inferior vena cava or AV valves.
No significant right to left shunting—closure would reduce cardiac output.
No other findings that require open heart surgery. This would lead to surgical closure of the ASD.

38. Case Study Experience of PSCCH
20 years old Saudi female was diagnosed to have ostium secundum. ASD and was referred from our OPD for closure of the defect.

73. Complications from percutaneous deployment of a ASD
Air embolism.
Vascular injury from large sheaths used to deploy the device.
Embolization, of thrombus formed on the device,
Perforation of the atrial wall, perforation of the aorta, infective endocarditis.
Atrial arrhythmias.
Malposition of the device requiring surgical retrieval.
Residual atrial shunts can occur in one-third of patients.

74. Place of Antiplatlets
During the months when an endothelial layer is expected to develop, thrombus of significant proportion can occur, leading some authors to recommend 6 months of antiplatlets after device implantation.

75. Reasons Behind Complications
Conclusion

76. Conclusion
ASD is the most common congenital heart disease encountered in adult .
ASD closing device is increasingly used with very promising results .
Team work is mandatory for success of the procedure .
Clinical and echocardiographic follow up is necessary after the procedure .
