Successful flutter catheter ablation through the azygos continuation due to an interrupted inferior vena cava.

Inferior vena cava IVC is a crucial route for catheter access (both directly to the right heart and indirectly through a transeptal puncture to the left heart, used in most electrophysiological procedures). However, interrupted IVC is a real challenge to traditional arrythmia ablation approaches, compromising in certain cases the success of the procedure. A well-developed azygos continuation offers an alternative pathway, bypassing the interrupted segment of the IVC.

Navigating challenges: Cleidocranial dysplasia and complexities in transvenous pacemaker implantation.

Cleidocranial dysplasia (CCD) is a rare genetic disorder characterized by skeletal abnormalities, including hypoplastic or absent clavicles, delayed closure of cranial sutures, and dental anomalies. We present a case of a 72-year-old female with a history of breast cancer treated with mastectomy and radio chemotherapy with the port-a catheter still in place in the left subclavian region. She presented to the emergency room with syncope related to a complete atrioventricular (AV) block.
