CHECKING FOR PERFORATION OF THE EPICARDIUM USING MAGNETIC RESONANCE IMAGING

摘要

Cardiac ablation is monitored to detect hemopericardium by iteratively acquiring magnetic resonance imaging (MRI) data that includes the pericardium, measuring the pericardium by analyzing the sets of MRI data, making a determination that a measurement of the pericardium in consecutive sets of MRI data differ, and responsively to the determination reporting a change in configuration of the pericardium.

主权项

1. A method, comprising the steps of:
inserting a probe into a heart of a living subject, the heart having a pericardium thereabout; navigating the probe into a contacting relationship with a target tissue of the heart; performing a medical procedure on the target tissue; iteratively acquiring magnetic resonance imaging (MRI) data that includes the pericardium, including a first set of MRI data and a second set of MRI data; measuring the pericardium by analyzing the sets of MRI data; making a determination that a measurement of the pericardium in the second set of MRI data differs from the measurement of the pericardium in the first set of MRI data; and responsively to the determination reporting a change in configuration of the pericardium, wherein the steps of iteratively acquiring, measuring, making a determination, and reporting are performed while performing the medical procedure.
