A method of performing an intracardiac procedure using controlled intermittent diastolic arrest (CIDA) to expand the chambers of the heart to a volume between about 75 to 200% of their normal end-diastolic volume. In one embodiment, CIDA is conducted so that cardiac arrest with cardiac distention is achieved in about 5 to 15 seconds and diastolic arrest is maintained for a time between about 5 and 90 seconds. Intracardiac procedures that are facilitated with CIDA include heart valve repair or replacement. The method involves the use of CIDA and wherein the procedure is performed in or on the heart with the use of a catheter or catheter-delivered device, therapy, or agent. |
