Why our team
Watchman (LAA Closure) is performed by the same cardiologists who follow you long-term. Because we're an independent group, your imaging, procedure, and follow-up stay within one practice — fewer hand-offs, fewer dropped details. Our team includes board-certified specialists across structural heart and adjacent disciplines, with hospital privileges across Mercy Health and ProMedica systems.
Watchman (LAA Closure) — common questions
- Will I still need blood thinners?
- Most patients take a short course of anticoagulation, then transition to aspirin alone after follow-up imaging confirms the device is sealed.
