Streamlined Denervation With spYral For an Optimized Treatment (SPYRAL SWYFT) in Subjects With Uncontrolled Hypertension

Официальное название

Sub-study of SPYRAL AFFIRM: Streamlined Denervation With spYral For an Optimized Treatment (SPYRAL SWYFT)

Обзор

The purpose of the SPYRAL SWYFT sub-study is to evaluate whether renal denervation with the Symplicity Spyral system performed in the main and first order branch renal arteries yields a shorter procedure time and is as effective in reducing blood pressure than the procedural approach used in the SPYRAL HTN-ON MED and SPYRAL PIVOTAL - SPYRAL HTN-OFF MED clinical studies in an uncontrolled hypertensive population.

Подробное описание

SPYRAL SWYFT will evaluate the long-term safety, efficacy, and durability of the Symplicity Spyral system to determine whether renal denervation performed in the main and first order branch renal arteries yields a shorter procedure time and is as effective in reducing blood pressure than the procedural approach used in the SPYRAL HTN-ON MED and SPYRAL PIVOTAL - SPYRAL HTN-OFF MED clinical studies (where all accessible renal arterial vessels between 3 and 8 mm in diameter including accessory, branch and main renal arteries (outside the kidney parenchyma) were targeted for ablation).

SPYRAL SWYFT study is conducted under the overarching SPYRAL AFFIRM protocol (NCT05198674), focused on EU and APAC regions.

Вмешательства

• Устройство Symplicity Spyral™ multi-electrode renal denervation system
  After a renal angiography according to standard procedures, subjects are treated with the renal denervation procedure.
