Now let me search the library for mitral stenosis content and run a PubMed search in parallel.

Braunwald's Heart Disease has the most detailed sections. Let me read those plus the echocardiography textbook in parallel.

Let me now get the core Braunwald's chapter on mitral stenosis (pathophysiology, clinical features, diagnosis, management) and the echocardiography content.

Excellent. Now let me read the core Braunwald's chapters and Harrison's sections in parallel.

Now let me get Harrison's MS section and the Schwartz surgery section and the treatment/BMV section from Braunwald's.

I now have rich material from Braunwald's and Schwartz's. Let me fetch one key image and get the Harrison's/Goldman-Cecil content on clinical features and management.

I now have excellent material. Let me get the clinical features/auscultation content and the anesthesia section on pathophysiology.

Let me fetch the pathophysiology flowchart image and get more detail on the Goldman-Cecil physical exam section.
