Summary
The Alto stent-graft offers promising early results for endovascular aneurysm repair (EVAR), enabling treatment in more patients with challenging aortic anatomy. Further studies are needed to confirm its long-term safety and effectiveness.
Area of Science:
- Vascular Surgery
- Medical Devices
- Aortic Aneurysm Treatment
Background:
- The Alto stent-graft is an advanced Ovation platform for endovascular aneurysm repair (EVAR).
- Its ultra-low profile and proximal sealing zone enhance eligibility for standard EVAR.
- This study reports early clinical and technical outcomes following CE Mark approval.
Approach:
- Seven male patients (mean age 76.1 years) underwent EVAR using the Ovation Alto stent-graft.
- Procedures were performed by experienced vascular surgeons between June 2021 and February 2022.
- Follow-up included duplex ultrasound and computed tomography angiography (CTA) at 1, 3, and 6 months.
Key Points:
- Technical success was achieved in all cases, with no type IA/IB/III endoleaks.
- On-label EVAR was feasible in patients with hostile aortic neck anatomy and narrow iliac arteries.
- No significant stent-graft migration or aortic neck variations were observed during follow-up.
Conclusions:
- Early outcomes indicate promising technical and clinical success for the Alto stent-graft.
- The device's design facilitates EVAR in a broader range of aortic anatomies.
- Further prospective studies and registries are essential to assess long-term efficacy and safety.

Oxygen delivery is critical in clinical care, especially for patients with respiratory disorders or those undergoing surgical procedures. Various systems, such as tracheostomy and the T-piece, deliver oxygen to the lungs, ensuring adequate arterial oxygenation.
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...
