Cardiac Arrest in the Cardiac Catheterization Laboratory: Combining Mechanical Chest Compressions and Percutaneous LV Assistance.

Objectives: The aim of this study was to evaluate the optimal treatment approach for cardiac arrest (CA) occurring in the cardiac catheterization laboratory.

Background: CA can occur in the cath lab during high-risk percutaneous coronary intervention. While attempting to correct the precipitating cause of CA, several options are available to maintain vital organ perfusion.

Cardiomyopathy induced by pulmonary sequestration in a 50-year-old man.

A 50-year-old black man presented at the emergency department with midsternal, nonradiating chest pressure and chronic dyspnea on exertion. Four years before the current admission, he had been diagnosed with nonischemic cardiomyopathy at another facility. After our complete evaluation, we suspected that his symptoms arose from left-to-left shunting in association with pulmonary sequestration, a congenital malformation.
