Pericardial Tamponade in a Newborn Following Umbilical Catheter Insertion.

We present a case of cardiac tamponade following umbilical venous catheterization in a neonate, an uncommon, yet potentially fatal complication. Timely diagnosis by echocardiography and urgent pericardiocentesis proved lifesaving.

Complete heart block following occlusion of the first septal perforator after coronary stenting.

We report a case of transient complete heart block following occlusion of the first septal perforator branch after stent deployment in the left anterior descending coronary artery. The patient was treated with temporary transvenous pacing and reverted spontaneously to normal atrioventricular conduction after 3 days.
