Inclusion Criteria: * Age 18 years or older. * Participant is scheduled for, referred for, or undergoing an electrophysiology, cardiac ablation, structural heart, or other cardiovascular procedure for which intracardiac echocardiography or an ICE catheter is clinically planned, requested, considered, or utilized. * A documented ICE-catheter procurement or device-access episode can be identified and evaluated under the study protocol. * Sufficient procurement, scheduling, clinical, or administrative information is available to determine device-access timing and study outcomes. * Participant falls within either the documented ICE catheter access-disruption cohort or the timely-access comparison cohort. * Able to provide informed consent when prospective consent is required by the applicable IRB determination, or eligible for inclusion under an IRB-approved waiver or alteration of consent where applicable. Exclusion Criteria: * Younger than 18 years of age. * No planned, requested, or clinically relevant intracardiac echocardiography catheter involvement in the associated cardiovascular procedure. * Procurement or clinical records are insufficient to establish the timing or final disposition of the device-access episode. * Device access occurred outside the predefined study observation period. * Procedure delay or cancellation is clearly attributable solely to an unrelated clinical or administrative circumstance and no qualifying ICE catheter access event occurred. * Participation would conflict with another protocol, institutional restriction, or applicable human-subject protection requirement. * Individuals for whom required authorization, consent, or permitted IRB-approved waiver criteria are not satisfied.
