A puzzling CHD: a late diagnosis of left atrial isomerism.

We present a case of a 41-year-old patient with an unknown complex cardiac anatomy, who was previously submitted to two cardiac surgeries. Using multimodality imaging, a retrospective diagnosis was established, revealing a heterotaxy syndrome (left isomerism).

Left ventricle implantable cardioverter defibrillator: a dextro-transposition of the great arteries case.

We present a case of a patient with dextro-transposition of the great arteries palliated with a Senning procedure and a long-term arrhythmic complication that required an intervention, with an Implantable Cardioverter Defibrillator (ICD) implantation in the sub-pulmonary ventricle (morphologically left). This case highlights the need to perform off-label procedures to deal with the long-term complications of these complex patients.
