Con la completa normalizaciòn de la funciòn ventricular,y la reabsorciòn completa del scaffold en la DA,este hombre de 43 anios no tendrà rastros ni de su infarto,ni de su tratamiento a los 47…
Y se espera que viva otros 50 anios, sin llevar una protesis permanente en el corazòn.

Como y porque puede ser mejor?
Racional:
PG, 45 years old
Hypertensive, and smoker.
Strong family history for CAD-MI
Persistent chest pain with diffuse ST-segment depression in
the anterior leads
Pre-treated with ASA 100mg and Clopidogrel 600mg
LAD after multiple balloon dilatations from the proximal to the distal segment
LAD after implantation of 5 BVS with occlusion of the diagonal branch
La DA es el vaso mas importante por pronostico a largo
plazo.
La enfermedad difusa de la DA es un limite de los DES
actuales, y tambièn de la cirugia cardiaca.
Se trata de un real unmet clinical need
La reconstrucciòn de la pared vascular despuès del
absorbiemiento de los scaffolds podrìa tener un enorme impacto
clinico.

PROSPECT ABSORB is an investigator initiated multicenter, randomized trial, which for the
first time will evaluate the ability of a bioresorbable scaffold to safely increase luminal
dimensions of vulnerable plaque
“PROSPECT ABSORB will test the feasibility of an interventional approach in preventing future
major adverse events arising from plaques which appear angiographically innocuous but are in fact
the source of future acute coronary syndromes" - Dr. Stone
Patients with plaque at high risk of causing future coronary events (plaque burden ≥70%)
