The results are intended to be used by qualified clinicians in conjunction with the patient's clinical history, symptoms, and other preprocedural evaluations, as well as the clinician's professional judgment. FEops HEARTguide™ ALPACA is not intended to replace the implant device instructions for use for final LAAO and TAVI device selection and placement.
Device Story
FEops HEARTguide™ ALPACA is a cloud-based software platform for preprocedural planning of structural heart interventions (LAAO, TAVI). It accepts DICOM-formatted CT images as input. The device utilizes AI-based, non-adaptive machine learning algorithms to perform automated segmentation of cardiovascular structures and identify anatomical landmarks. Clinicians access the results via a web application, which provides 3D visualizations, multi-planar reconstructions (MPR), and measurement tools. The system supports human-in-the-loop workflows where a FEops case analyst performs quality checks on the automated outputs before final clinician review. The output assists clinicians in sizing and planning interventions; it does not replace manufacturer instructions for implant selection. The device benefits patients by providing precise anatomical measurements to optimize procedural planning.
Clinical Evidence
Bench testing only. Performance validated using 70 retrospective cases (35 LAAO, 35 TAVI). LAAO cohort: mean age 76.2y; TAVI cohort: mean age 76.3y. Primary endpoints: mean diameter accuracy of landing zone (LAAO) and aortic annulus (TAVI) compared to manual ground truth. LAAO landing zone mean difference 1.4% (semi-automatic); TAVI annulus mean difference 0.5% (semi-automatic). Dice scores for segmentation ranged 0.93-0.98. Results met predetermined performance goals (±18% for LAAO, ±10% for TAVI).
Technological Characteristics
Cloud-based software for medical image management and processing. Utilizes AI-based, non-adaptive machine learning algorithms for automated segmentation and landmark identification. Inputs: DICOM CT data. Outputs: 3D surfaces, MPR, PDF reports. Connectivity: Cloud-hosted web application. Cybersecurity measures implemented. No hardware components.
Indications for Use
Indicated for preprocedural planning and sizing of structural heart interventions (LAAO and TAVI) in adult patients. Used by qualified clinicians to visualize and measure cardiovascular structures from CT images.

## PERFORMANCE DATA
Non-clinical performance data was included in the 510(k)-submission demonstrating FEops HEARTguide™ ALPACA has been validated for its intended use and is substantial equivalent to the predicate device. Software verification and validation was performed, and documentation was provided following the "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices". This includes verification against defined requirements, and validation against user needs. In addition, documentation following "Technical Performance Assessment of Quantitative Imaging in Radiological Device Premarket Submissions" was provided to demonstrate the performance of the quantitative imaging function included within FEops HEARTguide™ ALPACA. The results of the accuracy or performance validation are summarized below.
For LAAO, a study was performed on a cohort of 35 representative retrospective cases, during which quantitative outputs of FEops HEARTguide™ ALPACA were compared with manually annotated data (i.e. ground truth). The age of the studied cohort is 76.2±8.7y (50-92y), 51% were male subjects, and the LAA morphology was chicken wing (43%), reversed chicken wing (11%) or non-angulated (46%). Recent datasets representative for the intended population were used in this test cohort, covering different CT manufacturers, imaging parameters (e.g. slice thickness) and regions. No datasets were included that were used for training the AI models.
A performance goal was set for the mean diameter of the semi-automatically identified landing zone, as this is considered the most important landmark for the pre-operative planning of LAAO procedures. The maximum allowed difference in percentage must be less than the predetermined performance goal of ±18%.
The Bland-Altman analysis conducted on the mean diameter of the landing zone provided the following results for the semi-automatic and fully automatic outputs respectively:
| | Semi-automatic output | Fully automatic output |
|------------------------------------------|-----------------------|------------------------|
| Mean of differences (%) | 1.4 ± 4.6 | 4.1 ± 7.2 |
| Confidence interval (CI) on the mean (%) | (-0.2, 2.9) | (1.6, 6.6) |
| Inferior Limit of Agreement (LoA) (%) | -7.7 | -10.1 |
| Superior LoA (%) | 10.4 | 18.3 |
Image /page/11/Picture/8 description: The image shows the logo for FEOPS. The logo consists of the word "FEOPS" in large, bold, black letters, followed by the tagline "insights for excellence" in a smaller, lighter font. To the right of the text is a black speech bubble containing a white icon that resembles an open book or document.
{12}------------------------------------------------
| CI on inferior LoA (%) | (-10.5, -5.0) | (-14.4, -5.8) |
|------------------------|---------------|---------------|
| CI on superior LoA (%) | (7.7, 13.2) | (14.0, 22.6) |
For the semi-automatically identified landing zone, the lower limit of the CI calculated on the inferior LoA (-10.5%) and the upper limit of the CI calculated on the superior LoA (13.2%) are within the maximum allowed difference of ±18%, so the performance goal has been met. For all quantitative output, consistent performance has been observed for all relevant subgroups including CT manufacturers, imaging parameter, patient sex and age as well as LAA morphology.
The segmentation output was compared with manually annotated data (i.e. ground truth) by calculating the dice score on the region of interest: the region of the left atrium containing the ostium and the main part of the left atrial appendage.
| | Semi-automatic output | Fully automatic output |
|--------------------|-----------------------|------------------------|
| Mean dice score | $0.98 \pm 0.01$ | $0.93 \pm 0.04$ |
| Minimum Dice score | 0.95 | 0.83 |
| Maximum Dice score | 0.99 | 0.97 |

For TAVI, a study was performed on a cohort of 35 representative retrospective cases, during which quantitative outputs of FEops HEARTguide™ ALPACA were compared with manually annotated data (i.e. ground truth). The age of the studied cohort is 76.3±9.5y (48-91y), 46% were male subjects, and the aortic valve morphology was tricuspid in 74% of cases. Recent datasets representative for the intended population were used in this test cohort, covering different CT manufacturers, imaging parameters (e.g. slice thickness) and regions. No datasets were included that were used for training the AI models.
A performance goal was set for the perimeter-based diameter of the semi-automatically identified aortic annulus, as this is considered the most important landmark for the pre-operative planning of TAVI procedures. The maximum allowed difference in percentage must be less than the predetermined performance goal of ±10%. Please note that there is no automatically calculated perimeter-based diameter of the aortic annulus, as the algorithm only identifies the annular plane, and the measurement itself requires a manual action.

The Bland-Altman analysis conducted on the perimeter-based diameter of the aortic annulus provided the following results:
| | Semi-automatic output |
|------------------------------------------|-----------------------|
| Mean of differences (%) | 0.5 ± 1.9 |
| Confidence interval (CI) on the mean (%) | (-0.1, 1.2) |
| Inferior Limit of Agreement (LoA) (%) | -3.2 |
| Superior LoA (%) | 4.2 |
| CI on inferior LoA (%) | (-4.3, -2.1) |
| CI on superior LoA (%) | (3.1, 5.3) |
The lower limit of the CI calculated on the inferior LoA (-4.3%) and the upper limit of the CI calculated on the superior LoA (5.3%) are within the maximum allowed difference of ±10%, so the performance goal has been met. For all quantitative output, consistent performance has been observed for all relevant subgroups including CT manufacturers, imaging parameter, patient sex and age as well as aortic valve morphology.
The segmentation output was compared with manually annotated data (i.e. ground truth) by calculating the dice score on the region of interest: the region of the aortic root, including the ascending aorta and the left ventricle.
| | Semi-automatic output | Fully automatic output |
|--------------------|-----------------------|------------------------|
| Mean dice score | 0.97 ± 0.01 | 0.96 ± 0.01 |
| Minimum Dice score | 0.92 | 0.92 |
| Maximum Dice score | 0.99 | 0.98 |
| Median Dice score | 0.97 | 0.96 |

1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
