Valvular Diseases Flashcards
What is concentric hypertrophy?
Muscle thickens in LV most often in response to Aortic Stenosis
What is Eccentric hypertrophy?
The Dilation of the Heart Chanbers (LV) usually in response to regurgitation
What is the difference between acute hypertrophy and Chronic regurgitation?
- In acute regurgitation there will be a murmur without the hypertrophy (heart hasn’t had time to adapt)
- Rise in pressures
What are the clinical symptoms of Acute regurgitation?
- Heart Failure
- Chest Pain
- Syncope
- Arrhythmias
How does Aortic stenosis affect blood pressures?
There is a Gradient between Aorticsystolic BP and Ventricular systolic BP
In order to determine the severity of Cardiac Lesions What must one know?
- Flow (Cardiac Output)
2. Gradient
What is the most common cause of Mitral Stenosis?
Rheumatic fever
What is the Clinical result of Mitral Stenosis?
Right Heart Failure + Pulmonary congestion
What would dilatation of the Left Ventricle cause (Valvular disease)?
Mitral Regurgitation by pulling the supporting structure away from the valve with dilation
What is the most common cause of Mitral regurgitation?
Mitral Valve Prolapse
What is the most common cause of acute Mitral regurgitation?
- Infection
2. M.I
With a systolic murmur indicative of Atrial stenosis in patients 15-65 what is to be suspected?
Congenital abnormality of Aortic valve (Born with 2 leaflets vs 3) Bicuspid Aortic valve
With a systolic murmur indicative of Atrial stenosis in Children what is to be suspected?
Congenital Aortic valve defect (Unicuspid valve)
With a systolic murmur indicative of Atrial stenosis in patients >65 what is to be suspected?
Aortic valve degeneration, calcification
What are some of the Clinical signs of Aortic Stenosis?
- Concentric Hypertrophy
- Delayed Arterial Pulse= Tardus
- Weakened Arterial Pulse=Parvus
