Aortic Valve Stenosis Clinical Trial
— SAVVYOfficial title:
The SAVVY Guidewire in Transcatheter Aortic Valve Replacement Procedures: A Feasibility Study
TAVR patients exhibiting post-procedural residual AR had higher mortality and hospitalization rates due to heart failure, with the extent of this association increasing proportionally to the severity of the regurgitation. Optimizing transcatheter valve performance by intra-procedural hemodynamic evaluation of AR and residual transvalvular gradient remains of high clinical importance.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Presence of Major complications | Presence of major complications related to the SAVVY guidewire including (i) guidewire kink hindering or preventing the advancement of the transcatheter valve system | Periprocedural | |
Primary | Presence of Major vascular complications | Major vascular complications related to the SAVVY guidewire are defined as stroke, bleeding or left ventricular perforation | Periprocedural | |
Primary | Number of transcatheter valve malpositioning | Pacing capture failure translating into valve malpositioning. Valve malpositiong will be evaluated by a landing site to low or too high, leading to hemodynamically unfavorable results. | Periprocedural | |
Primary | Number of valve embolization | Pacing capture failure translating into valve embolization | Periprocedural | |
Primary | Number of effective rapid pacing run | Effective rapid pacing will be defined as an adequate ventricular pacing capture for a minimum of 10 seconds, with no capture loss, and leading to a reduction of aortic pressure of at least 50%, with/or a systolic pressure value <60 mmHg. Efficacy will be assessed by the physician. | Periprocedural | |
Primary | Number of accurate ventricular pressure | Accurate ventricular pressure will be defines as a pressure wire measurements similar (differences <5 mmHg) to those obtained simultaneously with a pigtail catheter in the same cavity or vascular segment (differences <5 mmHg in SBP, differences <5 mmHg in LVEDP). | Periprocedural |
