Six-year-old Ted had been diagnosed with subaortic
stenosis during a check-up for a heart murmur.
In addition to VSD closure, ASD closure performed in 10 patients, PDA ligation in 1 patient, and subaortic
membrane resection in 1 patient.
We report our very first experience in deploying Nit-Occlud (PFM, Cologne, Germany) devices for the purpose of occluding subaortic
aneurysmal ventricular septal defects at a tertiary cardiac center in Pakistan.
Other risks include restrictive interatrial communication, coronary compromise, pulmonary artery distortion, subaortic
obstruction, and arrhythmias.
The aorta arises from the right ventricle via a subaortic
infundibulum while the pulmonary artery arises directly from the left ventricle.
Diagnosis n Ventricular septal defect: multiple (2); muscular (1); 6 perimembranous (2); subaortic
(1) Atrial septal defect: secundum (5); primum (1) 6 Patent ductus arteriosus 4 Persistent left superior vena cava 2 Total anomalous pulmonary venous drainage 2 Hypoplastic left (1) or right (1) heart syndrome 2 Double outlet right ventricle 1 Coarctation of the aorta 1 Aortic stenosis 1 Vascular ring 1 Table 2: The primary cardiac surgical interventions performed during the first year of life in 10 children with primary reconstructed esophageal atresia (EA) and concomitant congenital heart disease (CHD).
Hauck et al., "Transesophageal echocardiographic recognition of subaortic
complications in aortic valve endocarditis.
For example, Med and EBUS-TBNA could not reach prevascular, subaortic
, paraaortic, paraesophageal, and pulmonary ligament nodes .
The abnormal accessory reverse-oriented tricuspid semilunar valve-like structure described in our case could remotely suggest subaortic
and carotid Velocity Time Integral (VTI) with a passive leg raise (PLR) has shown promising reliability; however measurements are more technically challenging and are more time-consuming to perform.
In dogs, the disease is called subaortic
stenosis (SAS) because the obstruction to flow is usually caused by fibrous tissue located proximal to the valve (Mac DONALD, 2006).
We first evaluated the potential risk factors including gender, age, weight, inlet and outlet diameters of defect, subaortic
rim length, occluder size, corrected occluder size into body surface area, fluoroscopy time, presence of aneurysm, and deployment position.
