Atrioventricular Septal Defect



  • We present an unusual case of a Down's syndrome patient whose septal defect first presented at 20 years of age.[ncbi.nlm.nih.gov]
  • The present patient showed very late onset pulmonary hypertension, which may be a critical parameter for survival.[ncbi.nlm.nih.gov]
  • After surgical correction of the shunt and the associated mitral incompetence, the patient experienced a good outcome.Echocardiographic and intraoperative findings are presented, along with a plausible explanation for the mechanism and presentation of[ncbi.nlm.nih.gov]
  • We present a case of this association treated with the previously unreported application of the cone reconstruction (da Silva repair) as a secondary strategy.[ncbi.nlm.nih.gov]
  • We present a review of rare intermediate type atrioventricular septal defect in the elderly, and we discuss the surgical issues in this case.[ncbi.nlm.nih.gov]
Large Ears
  • We report on a patient with a unique constellation of anomalies comprising trigonomicrocephaly, asymmetric severe micrognathia, large ears, atrioventricular septal defect, vertebral anomalies, bilateral cutaneous syndactyly of fingers and toes, unilateral[ncbi.nlm.nih.gov]
  • […] report on a patient with a unique constellation of anomalies comprising trigonomicrocephaly, asymmetric severe micrognathia, large ears, atrioventricular septal defect, vertebral anomalies, bilateral cutaneous syndactyly of fingers and toes, unilateral cryptorchidism[ncbi.nlm.nih.gov]


ST Elevation
  • She exhibited chest pain with ST elevation, and coronary computed tomography showed that the LMCA was compressed between the dilated pulmonary artery and aorta. After her hyperthyroidism was treated, her chest pain resolved.[ncbi.nlm.nih.gov]
Torsades De Pointes
  • Bradycardia secondary to heart block can lead to abnormal QT prolongation and precipitate Torsades de Pointes and arrest. Here, a case report of these events is described, together with a brief literature review.[ncbi.nlm.nih.gov]


  • We discuss her successful surgical treatment in terms of the available medical literature.[ncbi.nlm.nih.gov]
  • Two-patch technique through a transatrial approach alone is a good treatment choice for patients. Management of right ventricular outflow tract (RVOT) is similar to that of isolated TOF.[ncbi.nlm.nih.gov]
  • Three patients are still on vasodilator treatment 1, 2.6 and 6years after surgery, other two were lost to follow-up.[ncbi.nlm.nih.gov]
  • BACKGROUND: Primary repair is the preferred strategy for surgical treatment of complete atrioventricular septal defect combined with the tetralogy of Fallot. However, a staged approach may be preferable for very small or cyanotic infants.[ncbi.nlm.nih.gov]
  • Hence, treatment was conservative. At autopsy, a huge (3 cm diameter) ostium primum atrial septal defect (ASD) was found, together with deformation of the right and left atrioventricular valves and extreme dilatation of the heart.[ncbi.nlm.nih.gov]


  • Abstract Complete atrioventricular septal defect (CAVSD) is a fetal cardiac malformation (5% of all cardiac malformations) that can be detected prenatally with a reserved prognosis.[ncbi.nlm.nih.gov]
  • Single-stage repair of CAVSD and CoA appears to offer a good prognosis provided that valve morphology is amenable to repair.[ncbi.nlm.nih.gov]
  • Postnatal/Prognosis? Management of AVSD generally involves surgery. Outcomes vary widely based upon the presence of other abnormalities or genetic syndromes.[prenatalpediatrics.org]
  • Decreasing operative mortality has significantly altered the prognosis of these patients with and without Down’s syndrome.[heart.bmj.com]
  • Prenatal consultations with pediatric cardiology, pediatric cardiothoracic surgery, and neonatology specialists are recommended to discuss the prognosis and management after birth.[columbiaobgyn.org]


  • […] complications/etiology; reoperation; time factors; treatment outcome[ncbi.nlm.nih.gov]
  • PURPOSE: The genetic etiology of atrioventricular septal defect (AVSD) is unknown in 40% cases. Conventional sequencing and arrays have identified the etiology in only a minority of nonsyndromic individuals with AVSD.[ncbi.nlm.nih.gov]

  • The pathophysiology of atrioventricular septal defect is variable, and ranges from mild left to right shunting similar to a simple atrial septal defect to complex single-ventricle heart disease.[ncbi.nlm.nih.gov]
  • ., M.D. [1] Overview Pathophysiology There are many underlying mechanisms resulting in atrioventricular septal defect depends largely on the nature of interaction of blood flow between the right and left sides of the heart.[wikidoc.org]
  • Atrioventricular Septal Defect Pathophysiology: In pathophysiological terms, atrioventricular septal defect acts as a ostium secundum interatrial septal defect , which is associated with a mitral valve defect that is accentuating pulmonary stasis, increases[doctortipster.com]
  • The aim of this chapter is to present a model of how noninvasive multimodal imaging can improve the understanding of pathophysiology and increase the accuracy of the diagnosis of the specific congenital heart disease.[accessmedicine.mhmedical.com]
  • Pathophysiology If there is a defect in the septum, it is possible for blood to travel from the left side of the heart to the right side of the heart, or the other way around.[savetipedijatra.com]


  • ., La Ciotat Cedex, France) was placed beneath the atrioventricular valve to prevent rupture of the mitral aneurysm and support the anterior mitral leaflet by creating a new annulus.[ncbi.nlm.nih.gov]
  • The performance of preventive gesture during repair seemed to be unjustified. The surgical management of this reoperation consists of a simple and safe procedure. The Author(s) 2015.[ncbi.nlm.nih.gov]
