Long-term results of repair of incomplete persistent atrioventricular canal

Operation for partial atrioventricular septal defect: a forty-year review

“…The presence and severity of left atrioventricular valve regurgitation, stenosis, arrhythmias, and left ventricular out-T he first surgical correction of partial atrioventricular septal defect (ASD) was reported in 1955, 1 and since then there have been reports of several reasonably large operative series. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] The purpose of this study was to describe the long-term outcome of the largest reported series of patients who underwent surgical repair of partial ASD at one institution. We determined the incidences of survival, reoperation, and occurrence of significant left atrioventricular valve regurgitation, stenosis, left ventricular outflow tract obstruction, and arrhythmia.…”

Three‐Dimensional Transesophageal Echocardiographic Demonstration of Anatomical Defects in AV Septal Defect Patients Presenting for Reoperation

“…(ECHOCARDIOGRAPHY, Volume 20, January 2003) transesophageal echocardiography, three-dimensional echocardiography, cleft in left atrioventricular valve, partial atrioventricular septal defect, left ventricular to right atrial shunt Common features of atrioventricular (AV) septal malformations are anterior displacement of the AV junction, elongated left ventricular outflow tract, absence of the AV septum, abnormal position of the papillary muscles, abnormal AV valve leaflet configuration, and a cleft in the left AV valve. [1][2][3][4] Early surgical intervention is advisable, as the natural history of this complex defect is clinical deterioration by the fourth decade of life. 4,5 However, a common late postoperative complication is the development of clinically significant left AV valve regurgitation that may require reoperation.…”

“…4,5 However, a common late postoperative complication is the development of clinically significant left AV valve regurgitation that may require reoperation. 4 We present two-(2-D) and three-dimensional (3-D) transesophageal echocardiographic (TEE) findings of two adult patients who presented for reoperation for severe left AV valve regurgitation after previous repair of a partial AV septal defect. One patient had an additional 10 × 5 mm defect that connected the left ventricle to the right atrium through the AV junction.…”
