Abstract:

A retrospective reconstruction method uses cardiac self-gating for patients with severe arrhythmias. Self-gated myocardial systolic and diastolic motion is determined from low-spatial and high-temporal resolution images and then the MRI-data-set is retrospectively reconstructed to obtain high quality images. The method uses undersampled image reconstruction to obtain the low-spatial and high-temporal resolution images, including those of different beat morphologies. Processing of these images is utilized to generate a cardiac phase signal. This signal allows for arrhythmia detection and cardiac phase sorting. The cardiac phase signal allows for detection of end-systolic and diastolic events which allows for improved sampling efficiency. In the case of frequent and severe arrhythmia, the method utilizes data from the normal and interrupted beats to improve sampling and image quality.

Abstract:

A transvenously deployed myocardial restraint device provides mechanical restraint of a dilated left ventricle and improves heart function. The device includes a delivery wire with a restraining coil that is straightened for percutaneous delivery to the heart and recoiled once positioned in a pericardial space adjacent a ventricular heart wall. Alternatively, a balloon on the end of the delivery wire is delivered similarly to the coil and is then inflated in the pericardial space to restrain the dilated portion of the left ventricle. A trailing end of the coil forms a tether that is anchored to the left ventricular free wall and to the ventricular septum by an intraventricular septal anchor and connected by the tether through the ventricular septum using the same delivery system.
