- Learn the importance of heart sounds in diagnosing cardiovascular diseases.
2. Pathophysiology of Heart Murmurs
- Acquire knowledge of the underlying mechanisms that result in heart murmurs.
- Distinguish between systolic and diastolic murmurs and the clinical significance of each.
3. Mitral Valve Murmurs
- Deep dive into mitral valve murmurs’ types, causes, and manifestations, including mitral stenosis and mitral regurgitation.
- Understand how to differentiate these murmurs from others based on timing, quality, and anatomical landmarks.
4. Aortic Valve Murmurs
- Explore the key features of aortic valve murmurs, including aortic stenosis and aortic regurgitation.
- Learn the clinical indications that might suggest the presence of an aortic valve condition.
5. Diagnostic Criteria and Tools
- Familiarize yourself with diagnostic approaches based on the latest clinical guidelines, from auscultation to echocardiography.
- Learn the grading system for murmurs and the role of additional diagnostic modalities like Doppler studies.
6. Management Strategies for Mitral and Aortic Valve Murmurs
- Discuss evidence-based treatment options, from pharmacological interventions to valve replacement surgery.
- Review the indications for surgical referral and expected outcomes.
7. Potential Complications and Prognosis
- Learn about the potential adverse outcomes associated with untreated or mismanaged mitral and aortic valve conditions.

[@selzoo2270]

I have a little doubt regarding decrease in intensity of murmer due to mitral prolapse on increasing afterload. Aortic pressure is high, so the blood isnt able to go through aorta, leading to incomplete ejection, which will force blood in to mv prolapse and cause murmer right, that's what i thought😅, why does it doesn't buckle on increasing afterload Somebody please explain

[@fxiry_shimmy_shimmy_ya05]

Please put back your long and detailed individual videos on heart sounds and heart murmur s
