# ESC Guidelines Query System

Expert system for querying ESC Guidelines with automatic PDF location and citation extraction.

## When to Use This Skill

- Answering clinical cardiovascular questions
- Finding ESC recommendations on specific conditions
- Extracting diagnostic or therapeutic guidelines
- Locating specific ESC criteria or thresholds
- Comparing recommendations across different ESC guidelines
- Verifying treatment protocols against ESC standards

## Core Workflow

This skill implements a **3-phase intelligent retrieval system**:

### Phase 1: TOC Analysis (Locate)
**Goal**: Identify which ESC guideline PDF contains the relevant information

**Process**:
1. **Read** the master index: `ESC_GUIDELINES_TOC.md`
2. **Analyze** the user's clinical question to extract:
   - Medical condition (e.g., "aortic aneurysm", "atrial fibrillation")
   - Specific aspect (e.g., "imaging", "treatment threshold", "follow-up")
   - Clinical context (e.g., "45mm diameter", "pregnancy", "diabetes")
3. **Search** the TOC using Grep with relevant keywords
4. **Identify** the specific PDF file and page/section numbers

**Example TOC Analysis**:
```markdown
User Question: "Si deve fare TAC se uno ha 45mm di aortic root?"

Keywords to search: aortic root, imaging, CT, TAC, surveillance, thoracic aorta, 45mm

TOC Result:
- File: 2024_Peripheral_Arterial_Aortic.pdf
- Section: 9.2.2 Thoracic aortic aneurysms (p. 66)
- Subsection: 9.2.2.4 Surveillance (p. 70)
- Imaging section: 5.4 Evaluation of the aorta (p. 25)
```

### Phase 2: PDF Extraction (Read)
**Goal**: Read the specific sections from the identified PDF

**Process**:
1. **Open** the PDF file identified in Phase 1
2. **Navigate** to the specific sections/pages from the TOC
3. **Extract** relevant content including:
   - Recommendations (with class/level of evidence)
   - Diagnostic criteria
   - Threshold values
   - Imaging protocols
   - Follow-up schedules
4. **Capture** exact quotes for citation

**Reading Strategy**:
```markdown
Priority reading order:
1. Main section related to the question
2. Imaging/diagnostic section if relevant
3. Management/treatment section
4. Surveillance/follow-up section
5. Special populations section if applicable
```

### Phase 3: Answer Synthesis (Cite)
**Goal**: Provide accurate answer with proper citations

**Required Elements**:
1. ✅ **Direct answer** to the user's question
2. ✅ **ESC Recommendation** (Class I/IIa/IIb/III, Level A/B/C)
3. ✅ **Exact citation** (PDF file, section, page number)
4. ✅ **Clinical context** (thresholds, conditions, exceptions)
5. ✅ **Related information** (surveillance intervals, imaging modality choice)

**Citation Format**:
```markdown
**ESC Recommendation** [Class I, Level B]:
"[Exact quote from PDF]"

**Source**: [2024_Peripheral_Arterial_Aortic.pdf] - Section 9.2.2.4 (p. 70)
```

## Example Query Execution

### User Question
> "Si deve fare TAC se uno ha 45mm di aortic root?"

### Phase 1: Locate
```bash
# Search TOC
Grep: "aortic root|imaging|CT|TAC|thoracic.*aneurysm|surveillance"
File: ESC_GUIDELINES_TOC.md

# Result
PDF: 2024_Peripheral_Arterial_Aortic.pdf
Sections:
- 5.4 Evaluation of the aorta (p. 25)
  - 5.4.6 Cardiovascular computed tomography (p. 29)
- 9.2.2 Thoracic aortic aneurysms (p. 66)
  - 9.2.2.4 Surveillance (p. 70)
```

### Phase 2: Read
```bash
# Open PDF
Read: references/esc-guidelines/2024_Peripheral_Arterial_Aortic.pdf

# Extract from Section 5.4.6 (p. 29)
"CT angiography is the gold standard for aortic imaging..."

# Extract from Section 9.2.2.4 (p. 70)
"Surveillance with CT or MRI is recommended when aortic diameter is ≥45mm..."
[Recommendation Class I, Level B]
```

### Phase 3: Cite
```markdown
# Imaging per Aortic Root di 45mm

## ESC Recommendation

**Class I, Level B**: La sorveglianza con TC o RM è raccomandata quando il diametro aortico è ≥45mm.

"Surveillance imaging with CT or MRI is recommended when the aortic root diameter reaches 45mm or greater, with annual follow-up for diameters 45-49mm."

## Clinical Context

- **Threshold**: ≥45mm richiede imaging di conferma e sorveglianza
- **Imaging Modality**: TC angiografia (gold standard) o RM cardiovascolare
- **Surveillance Interval**: Annuale per 45-49mm
- **Surgery Threshold**: ≥50-55mm (salvo fattori di rischio)

## Indicazioni Specifiche per TC

| Condizione | Raccomandazione | Classe/Livello |
|------------|-----------------|----------------|
| Prima misurazione ≥45mm | TC o RM per conferma | Class I, Level C |
| Follow-up annuale | TC o RM | Class I, Level B |
| Valvola bicuspide + ≥45mm | TC annuale | Class I, Level B |
| Marfan + ≥45mm | TC ogni 6-12 mesi | Class I, Level C |

## Source Citation

**PDF**: [2024_Peripheral_Arterial_Aortic.pdf](references/esc-guidelines/2024_Peripheral_Arterial_Aortic.pdf)
**Sections**:
- 5.4.6 Cardiovascular computed tomography (p. 29)
- 9.2.2.4 Surveillance (p. 70)

## Additional Recommendations

- La TC senza contrasto può essere sufficiente per follow-up dimensionale
- La RM è preferibile in pazienti giovani per ridurre esposizione radiante
- L'ecocardiogramma può essere usato per screening ma non per decisioni chirurgiche
```

## Best Practices

### 1. Keyword Selection
- Use **medical synonyms** (e.g., "myocardial infarction" = "MI" = "heart attack")
- Include **Italian and English** terms
- Search for **abbreviations** (e.g., "AF" for atrial fibrillation)

### 2. TOC Navigation
- Start with **broad section search** (e.g., "aorta", "arrhythmia")
- Narrow to **specific subsections** (e.g., "surveillance", "imaging")
- Check **multiple related sections** (diagnosis, treatment, follow-up)

### 3. PDF Reading
- **Read tables first** - often contain key recommendations
- Look for **highlighted boxes** - ESC recommendations are emphasized
- Check **figures/algorithms** - provide decision pathways
- Don't skip **page headers** - confirm you're in the right section

### 4. Citation Accuracy
- **Quote exactly** - don't paraphrase recommendations
- **Include class/level** - essential for clinical decision-making
- **Provide page numbers** - for user verification
- **Link to PDF** - enable direct access

### 5. Clinical Context
- Mention **patient-specific factors** (age, comorbidities)
- Note **variations** by condition (bicuspid valve, Marfan syndrome)
- Include **surveillance schedules** - not just one-time recommendations
- Highlight **contraindications** or special considerations

## Common Pitfalls to Avoid

❌ **Don't:**
- Rely on TOC alone without reading the PDF
- Paraphrase recommendations (lose precision)
- Omit class/level of evidence
- Ignore special populations sections
- Miss related sections (e.g., imaging section when answering treatment question)

✅ **Do:**
- Cross-reference multiple sections
- Extract exact quotes
- Include all relevant thresholds
- Mention alternative approaches
- Cite page numbers for verification

## Performance Optimization

### Efficient TOC Search
```bash
# Use multiple keywords with OR
Grep: "aortic root|radice aortica|ascending aorta"

# Include Italian medical terms
Grep: "scompenso|insufficienza|ipertensione"

# Search for diagnostic terms
Grep: "imaging|CT|TAC|eco|RM|angio"
```

### Parallel Reading
When question involves multiple aspects:
1. Read **diagnostic section** (Phase 2a)
2. Read **treatment section** (Phase 2b)
3. Read **surveillance section** (Phase 2c)
4. Synthesize all in Phase 3

### Smart Caching
- Remember **frequently accessed PDFs** (e.g., 2024 guidelines)
- Note **common sections** for quick reference
- Build **mental map** of TOC structure

## Advanced Query Patterns

### Pattern 1: Comparative Questions
> "Quale imaging è meglio per aneurisma aortico, TC o RM?"

**Strategy**:
1. Locate imaging section in TOC
2. Read both CT and MRI subsections
3. Create comparison table with recommendations
4. Cite both sections

### Pattern 2: Threshold Questions
> "A che diametro si opera l'aorta ascendente?"

**Strategy**:
1. Locate surgical management section
2. Extract all threshold values
3. Note variations by condition
4. Present as structured table

### Pattern 3: Special Population Questions
> "Come gestire aneurisma aortico in gravidanza?"

**Strategy**:
1. Search TOC for "pregnancy" or "gravidanza"
2. Check both main section + pregnancy subsection
3. Extract pregnancy-specific recommendations
4. Note differences from general population

### Pattern 4: Multi-guideline Questions
> "Le linee guida 2024 cambiano il management dell'aorta rispetto al 2020?"

**Strategy**:
1. Locate same section in both TOCs
2. Read both PDFs in parallel
3. Create "What's new" comparison
4. Cite both guidelines with year
