Cardiac magnetic resonance imaging. A) Four-chamber view with visualization of the atretric tricuspid valve (arrow) and the residual right ventricle. B) Sagittal view with visualization of the non-restrictive ventricular septal defect (white arrow), the pulmonary valve (red arrow), and the residual non-restrictive pulmonary banding (black arrow).

We report on a 33 year-old male patient followed at our center for a unrepaired tricuspid atresia type IC with unrestricted ventricular septal defect with left-right shunting, a non-restricted atrial septal defect with right-left shunting, and a functional single left ventricle with normal systolic function (Fig. 1).
Injection sites for the modified superficial cervical plexus block. A line connecting the mastoid process to the clavicle on the anterior and posterior edge of the sternocleidomastoid was drawn. A total of 29 mL of lidocaine 1% with adrenalin was distributed on both sides as follow: middle of the posterior margin of the sternocleidomastoid (corresponding to the emergence of the superficial cervical plexus), anteriorly and longitudinally at 3 points (cervical branches), in the sternocleidomastoid muscle itself, and along the cervical incision.
