Transcatheter baffle leak closure via an amplatzer septal occluder in a senning-operated child

Senning operation is a surgical treatment for transposition of great arteries that can be complicated by post-procedural atrial or caval baffle leaks. We present a 6-year-old boy with a history of Senning repair for transposition of great arteries, who developed a pulmonary venous baffle leak. Percutaneous baffle leak closure was successfully performed using an Amplatzer septal occluder.

Left Atrial Volumetric and Deformation Analysis in Adult Patients with Dextro-Transposition of the Great Arteries (Insights from the CSONGRAD Registry and MAGYAR-Path Study)

Background: In complete or dextro-transposition of the great arteries (dTGA), the aorta and the pulmonary artery are transposed. The present study was designed to examine dTGA-associated left atrial (LA) volumetric and functional abnormalities in adult patients late after repair and to compare their results to those of healthy controls. Methods: The present study consisted of 15 dTGA patients (30.3 ± 8.1 years, 9 males), the patients had Mustard (n = 8) or Senning (n = 7) procedure performed. Their results were compared to those of 36 age- and gender-matched healthy subjects (28.7 ± 1.5 years, 24 males). Results: Increased maximum LA volume and reduced LA emptying fractions respecting the cardiac cycle could be demonstrated in our dTGA patients. LA stroke volumes representing all LA functions were significantly reduced. Peak LA circumferential, longitudinal, and area strains and LA circumferential, longitudinal, and area strains measured at atrial contraction were reduced in our dTGA patients. Most LA strains were reduced in patients having Mustard surgery compared to controls and patients undergoing Senning operation. Conclusions: Significant LA volumetric and functional abnormalities could be demonstrated in adult patients with dTGA late after repair. Senning procedure seems to have more beneficial long-term effects on LA volumetric and functional features as compared to the Mustard procedure.

CMR for transposition of the great arteries

In this chapter, a cardiovascular magnetic resonance (CMR) imaging approach to complete transposition of the great arteries after atrial redirection (Mustard or Senning operation) or arterial switch surgery is discussed, as well as the Rastelli procedure for transposition of the great arteries, ventricular septal defect, and pulmonary stenosis. Congenitally corrected transposition of the great arteries, either unoperated or following anatomical or physiological repair, is also described. In these conditions, CMR is acknowledged to have high utility, including for accurate quantification of right, as well as left, ventricular function, to enable imaging of the aorta and pulmonary arteries, baffles, and conduits, and for the identification of myocardial fibrosis. Information from CMR aids prognostication and planning of intervention.

Patient with D transposition of Great Arteries Operated by Senning Procedure: A Case Report

The atrial switch operation, the Mustard or Senning operation, for the transposition of the great arteries (TGA) was introduced in the late 1950s and was the preferred surgery for TGA until the early 1990s. The arterial switch operation has become the procedure of choice for patients with transposition of the great arteries (TGA) in most medical centres. Although atrial switching may occasionally be employed in some centres in cases with delayed diagnosis, pulmonary hypertension and some other unusual entities. We preferred to use the atrial switch operation Senning procedure for 5 months old child with TGA, small atrial septal defect (ASD) and patent ductus arteriosus (PDA).Journal of Current and Advance Medical Research 2017;4(1):31-33
