Valvular Heart Disease Lecture Powerpoint Flashcards
fuck d
Imaging study of choice for most valvular diseases
-Echocardiogram
Primary symptom of most valvular diseases regardless of whether its insufficiency or stenosis, mitral or aortic
Dyspnea
Left vs right cusps and corresponding coronary artery
Left cusp is over the left atrium and guards the left main coronary artery
Right cusp is over the right ventricle and guards the right coronary artery
Most common structural anatomic congenital disease in patients
VSD
Most common valvular anatomical congenital disease in patients
Bicuspid aortic valve
Bicuspid aortic valves are associated with these conditions (3)
- cystic medial degeneration (tunica media degenerates and forms aneurysm)
- aneurysmal dilation of ascending aorta
- subvalvular and supravalvular aortic stenosis (rare)
Rating of stenotic valves (4)
Mild, moderate, severe, or critical
3 symptoms of aortic stenosis
-syncope
-angina (coronary steal syndrome, blood not coming back during diastole)
-dyspnea
(SAD)
Most common cause of acquired aortic stenosis
Senile degenerative calcification (most common with age)
Dobutamine stress testing and pseudo AS
When undergoing testing with dobutamine does not see increase in gradient difference, indicating failure of muscle rather than valve problem
Unless symptomatic, ____ is not recommended for treatment of AS because…
heart surgery
…if asymptomatic, no increase in life expectancy by doing so
Acquired Aortic Stenosis prognosis and treatment (3)
-good until symptoms develop (then 3 year mortality is 50%)
-Treatment is artificial valve replacement (bioprosthetic or mechanical) or TAVR
or balloon valvuloplasty in extreme cases
Acquired aortic insufficiency causes (3)
- senile degenerative calcification
- systemic hypertension
- idiopathic annuloaorticectasia (no known cause)
Acquired aortic insufficiency symptoms (3)
- dyspnea on exertion
- orthopnea
- CHF
Aortic insufficiency can sequallae into…
….LV dilation from diastolic overload
Mussett’s sign
Slight head bobbing rare but occasionally seen in end stage valvular diseases
Acquired aortic insufficiency prognosis and treatment (3)
- poor with progression of signs and symptoms or CHF
- Vasodilator therapy, afterload reduction with diuretics, or AVR surgery
Aortic insufficiency is not a pressure dysfunction, but rather a…
….volume overload
