NCT ID: NCT03343314 Completed - Clinical trials for Calcific Aortic Stenosis

Effective Management of Calcific Aortic Stenosis in the Elderly

RAC
Start date: September 2016
Phase:
Study type: Observational

Although aortic valve replacement is recommended for any symptomatic severe calcific aortic stenosis, the therapeutic decision may be difficult. because of patient age and comorbidities. Transcatheter Aortic Valve Implantation (TAVI) has recently extended the therapeutic indications in patients at high risk of surgery. However, the proportion of different treatments is not known in a contemporary population that can be treated according to the different resources currently available. The scientific goal of this observational research is to evaluate intra-hospital therapeutic decision in elderly patients referred because of symptomatic severe aortic stenosis. The one-year survival will be analyzed according to the therapeutic decision and the characteristics of the patients.

NCT ID: NCT02184442 Completed - Clinical trials for Calcific Aortic Stenosis

The PARTNER II Trial: Placement of AoRTic TraNscathetER Valves - PII B

PARTNERII B
Start date: March 9, 2011
Phase: N/A
Study type: Interventional

The purpose of this study is to determine the safety and effectiveness of the SAPIEN XTâ„¢ THV with the associated delivery system for inoperable patients with severe symptomatic native aortic stenosis.

NCT ID: NCT02132026 Completed - Clinical trials for Calcific Aortic Stenosis

Study Investigating the Effect of Drugs Used to Treat Osteoporosis on the Progression of Calcific Aortic Stenosis.

SALTIRE II
Start date: November 12, 2014
Phase: Phase 2
Study type: Interventional

Aortic stenosis is a condition whereby one of the heart valves (aortic valve) becomes narrowed, due to calcium deposition, over time. This can lead to chest pain, heart failure and sudden death. It is the commonest valve disease requiring surgery in the developed world and as the population becomes increasingly older, it is predicted that the prevalence of aortic stenosis will double in the next 20 years. Currently the only treatment is replacement of the aortic valve. Whilst this is excellent treatment, not everyone is suitable for it. The primary objective of our study is to determine whether 2 drugs used in the treatment of osteoporosis (a condition of bone thinning) can halt/retard the progression of aortic stenosis. This is on the basis that studies have suggested that altered regulation of calcium metabolism may be an important mechanism perpetuating the disease. Both drugs work by reducing calcium release into the bloodstream from bones and therefore calcification of the aortic valve. 150 patients will therefore be randomly allocated to either of the trial drugs which are denosumab,the bisphosphonate (alendronic acid), or a placebo. Positron Emission Tomography (PET) scanning is a technique where biochemically active molecules are injected and are taken up at sites of ongoing calcification activity where they emit radiation and can be detected by the PET scanner. We have previously shown that this technique can demonstrate areas of newly developing calcification on an aortic valve. We therefore propose that patients receiving bisphosphonates or denosumab will have reduced evidence of active calcification and slower progression of their disease at two years as assessed by Echocardiography (ultrasound) and a change in their calcium score (quantity of calcium on the aortic valve measured using Computed Tomography [CT] ). The data from this study will then be used to design a larger trial.
