Perfuração de ventrículo esquerdo durante cateterismo cardíaco diagnóstico

Perforation of a heart chamber is a major complication of cardiac catheterization, an extremely rare condition, although its potential severity is well documented. We describe a case of perforation of the left ventricle occurred after a left ventriculography with a pig tail catheter, followed by cardiovascular collapse due to cardiac tamponade. This situation was handled with prompt pericardiocentesis, which led to clinical stabilization and case resolution.
