The Medtronic Solara™ Quad CRT-P MRI SureScan™ (Model W4TR06) is a dual-chamber, implantable cardiac resynchronization therapy pacemaker (CRT-P) designed for patients with heart failure. It features MRI compatibility (1.5T/3T), 19.5 mL volume, 30 g mass, and uses PhysioCurve design for patient comfort.
Key Features and Specifications (W4TR06):
- MRI Access: SureScan technology allows full-body MRI scanning.
- Size: 59 mm (H) x 46.5 mm (W) x 11 mm (D).
- Connector: 1 IS-4 and 2 IS-1 connectors.
- Heart Failure Management: Provides CRT therapies to improve ventricular synchrony and heart efficiency.
- Monitoring: Compatible with device diagnostics.
Clinical Indication:
These devices are typically indicated for patients with NYHA Functional Class III and IV heart failure, who remain symptomatic despite stable, optimal heart failure medication, and have a reduced left ventricular ejection fraction (LVEF \(\le \) 35%) and prolonged QRS duration.
Warnings and Contraindications:
- Contraindicated for concomitant use with another bradycardia device or an ICD.
- The device should be replaced prior to the Elective Replacement Indicator (ERI) to avoid loss of therapy.
- MRI suitability requires specific conditions, including no broken leads or abandoned leads.
