The disease is considered moderately severe at an approximately 1.5 cm square orifice. The leaflets become heavily calcified and immobile in advanced stages, reducing the orifice to less than 1 cm square. 00:05:00 Changes in S1 due to valve changes 00:09:25 S1 genesis in normal healthy individuals 00:10:15 S1 genesis in Mitral Stenosis 00:11:55 Quick Recap: Why is S1 loud in Mitral Stenosis? 00:13:00 Example: A normal mitral valve can be compared to a thin, pliable door that is slightly open and closes gently under minimal pressure. In contrast, a stenotic mitral valve is like a thick, wide-open door that requires high pressure to shut forcefully. 00:13:50 Advanced Mitral Stenosis: Soft S2 mechanism 00:15:36 Mitral Stenosis with A-fibrillation 00:16:45 Normal Conduction System 00:18:05 Conduction System in Mitral Stenosis 00:20:30 Thromboembolism mechanism in Mitral Stenosis 00:23:00 Mechanism of beat-to-beat intensity variation in Mitral Stenosis 00:25:00 Quick Recap: Mechanism of beat-to-beat intensity variation in Mitral Stenosis 00:26:20 Quick Recap: Changes in S1 in Mitral Stenosis 00:28:10 Overview of next lecture: Opening snap, Mid-Diastolic Murmur, Pre-Systolic Accentuation Loud P2, Graham Steell Murmur. Learn about the changes in heart sounds during mitral valve stenosis and how they manifest in different phases. Understanding heart sounds is crucial for proper auscultation, especially when examining variations in heart rate. This comprehensive lesson covers how heart murmur characteristics change from early to late stages, focusing on vital clinical assessment skills. 🩺 --------------------------------------------------------------------------------------------------------------------------- Join this channel to get access to the perks: Sign up now on our website at https://members.drnajeeblectures.com/ Follow us on Facebook:- https://www.facebook.com/DrNajeeb/ Follow us on Instagram:- https://www.instagram.com/drnajeeblectures/
