The Pressure-controlled Intermittent Coronary Sinus Occlusion on VentrIcular PERformance Study

"PICSO therapy is delivered through the PICSO Impulse System, which consists of the PICSO Impulse console and PICSO impulse catheter. The PICSO therapy is delivered in each patient for a minimum of 20 minutes to a maximum of 45 minutes.~The PICSO Impulse catheter is automatically activated by the PICSO Impulse console. It is inserted in the coronary sinus via femoral vein access. The PICSO Impulse Console cyclically inflates and deflates the balloon at the tip of the PICSO Impulse catheter, generating transient increase in coronary sinus pressure."
