Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Objectives:

Goal of the study is to investigate the potential benefit that transcatheter interventions such as Transcatheter Aortic Valve Implantation (TAVI), MitraClip, Left Atrial Appendage Closure and catheter Ablation can gain from multimodal image fusion techniques as they are available in the Hybrid suite.

Both the HeartNavigator and the EchoNav aim at decreasing the exposure to radiation and contrast agent, to shorten the operation time (efficacy), and to increase the quality of care (safety).

This pilot study aims at observing these aims on a small patient population and a control group.

Number of Subjects:

140 patients total in 6 groups:

* MitraClip, Left Atrial Appendage Closure or catheter Ablation with EchoNav (20, lead-in stage).
* MitraClip randomized with EchoNav (25), MitraClip randomized without EchoNav (25).
* TAVI with HeartNavigator lead in (10)
* TAVI randomized with HeartNavigator (30), TAVI randomized without HeartNavigator (30).

Detailed Description

Medical Device:

HeartNavigator: System for preoperative image-based assessment of aortic root geometry, planning of transcatheter aortic valve implantation, and intraoperative C-Arm control.

EchoNav: System for intraoperative registration of 3D Echo images with X-ray fluoroscopy images.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Male and female patients over 18 years of age.
* Ability and willingness to give informed consent.
* Indication for TAVI, MitraClip, catheter ablation or percutaneous closure of the left atrial appendage procedure performed in the hybrid OR suite.
* Recent good quality CTA (TAVI patients only, no CTA needed for EchoNav).

Exclusion Criteria

* Contraindications on ethical grounds,
* Women who are pregnant or breast feeding,
* Emergency cases,
* Contraindication or known hypersensitivity to contrast media which is unresponsive to pretreatment with steroids and antihistamines,
* Known renal insufficiency (GFR \< 50 ml/min) and patient is not on chronic hemodialysis (TAVI patients only, no contrast agent is necessary during MitraClip and transseptal puncture),
* Contraindications for transesophageal Echo (EchoNav patients only, TAVI is possible without TEE and TEE is not needed for the HeartNavigator),
* Known or suspected drug or alcohol abuse,
* Enrollment into a clinical trial within last 4 weeks if overlapping enrolment is not explicitly approved by ethics committee for the two trials,
* Patient is unable or unwilling to cooperate with the study protocol.
