Endovascular Treatment of Acquired Atheromatous Postsubclavian Aortic Coarctation.

Coral reef aorta is a rare calcifying obstructive disease that involves the thoracoabdominal aorta. Similar presentations in the postsubclavian aorta may result in acquired atheromatous aortic coarctation leading to systemic hypertension and heart failure. The associated calcification makes surgical anatomic or extraanatomic bypass and thromboendarterectomy challenging.

Cobra-head and other shape-memory abnormalities of nitinol atrial septal occluders: incidence, predisposing factors, and outcomes.

Background: Shape-memory abnormalities are seen in some nitinol atrial septal occluders. Variably described as cobra-head, tulip, and others, their incidence, mechanisms, clinical impact, and outcome have not been systematically analysed.

Methods: We retrospectively reviewed all consecutive device closures in the last 6 years for deformations.

Transcatheter reduction in size of large undesirable fenestrations following extracardiac conduit Fontan surgery with off-label use of Occlutech atrial flow regulator.

Fontan surgery streamlines the systemic venous return through the pulmonary circulation before filling the systemic ventricle in univentricular hearts. The venous congestion leads to effusions, lowers cardiac output, and affects organ perfusion. Fenestrations in the Fontan circuit improve forward flow through the ventricles, lower venous pressures, and reduce perioperative morbidity.

Successful percutaneous retrieval of unusually knotted temporary pacemaker lead.

Implantation of temporary pacemaker lead is commonly performed procedure and is usually safe, but can sometimes develop rare and serious complication like intracardiac lead knotting which may require challenging retrieval techniques. We report a case of successful percutaneous retrieval of unusually knotted right internal jugular venous temporary pacing lead via left femoral transvenous approach using snare over a long sheath after cutting the electrode proximally and thus avoiding any surgical intervention.
