Adult Congenital Heart Disease

3D TTE is useful for patients who previously underwent atrial switch procedures to assess for long-term complications including baffle leaks (Figure 16.42) and obstruction, which 2D TTE can miss.40 Importantly, the measurements obtained from 3D TTE have been consistent with data obtained intraoperatively, confirming its accurate description. This information gives cardiologists a more confident sense of the size, shape, and morphology of the defect and can assist in appropriate presurgical preparation and eventual repair. Intra-atrial baffle obstructions occur in as many as 40% of patients undergoing the Mustard procedure, making its identification crucial. Diagnosis of the presence and severity of intra-atrial baffle obstruction by 3D TEE is able to be made by offering an en face short-axis view, which 2D TTE is unable to capture (Figure 16.43).41

Systemic right ventricle (S-RV) describes the anatomy and physiology where a morphological right ventricle serves as the systemic ventricle. This condition is found in patients who are born with congenitally corrected transposition of the great arteries (ccTGA). S-RV also occurs after Senning or Mustard surgery for transposition of the great arteries (TGA), where a surgical atrial redirection leaves the right ventricle in the systemic position. The Senning or Mustard procedure was the treatment of choice in TGA before the era of the arterial switch operation in the late 1980s. Over time, the systemic RV (S-RV) may fail in both groups of patients. Failure of an S-RV represents a common clinical challenge at adult congenital heart units worldwide [1–3].
Leadless Micra pacemaker implantation in patient with previous Senning procedure for dextro-transposition of the great arteries

Mitchell et al. report on a case of Micra implantation in the left atrial appendage of a patient who have previously undergone a Mustard procedure [14]. Although the Micra device was not specifically designed for atrial implantation, clinical trials are currently underway of the Aveir DR dual chamber leadless pacing system, which incorporates a dedicated leadless atrial pacemaker with an active fixation helix utilising a screw-in mechanism for deployment.
