|
List three indications for balloon pulmonary valvuloplasty
|
1. Critical valvar PS (ductal-dependent); 2. peak to peak cath or peak echo gradient >40; 3. valvar PS with symptoms, RV dysfunction, or shunt-mediated cyanosis
|
|
|
What balloon: annulus ratio is recommended for pulm valvuloplasty?
|
1.2-1.4x the annulus
|
|
|
Treatments for suicide RV
|
volume, restart PGE, beta blocker, RVOT stent
|
|
|
List indications for balloon aortic valvuloplasty
|
1. Critical AS (ductal-dep); 2. AS + depressed LV function (regardless of gradient); 3. Peak cath gradient >50; 4. Peak cath gradient >40 + symptoms
|
|
|
What echo gradient needed for cath to consider balloon aortic valvuloplasty?
|
Use mean Doppler gradient >40 to refer for cath if aysymptomatic. If pregnant or desiring to do competitive sports, can use gradient >30.
|
|
|
What balloon: annulus ratio is recommended for aortic valvuloplasty?
|
0.8-1x the aortic annulus
|
|
|
How is >moderate mitral stenosis defined (cath)
|
peak gradient >20, mean >15, near systemic PA pressure; MV area <1 cm/m2, and symptoms
|
|
|
What are indications for branch PA angioplasty?
|
Peak gradient 20-30, RVp > 1/2 to 2/3 systemic; flow discrepancy greater than 35/65; angiographic apperance of significant narrowing
|
|
|
What are indications for coarctation balloon?
|
recoarctation ONLY with gradient >20 by cath vs. recoarctation gradient <20 with collaterals, single V, or ventricular dysfunction
|
|
|
How to size balloon for coarctation
|
Balloon diameter = 2-3x diameter of stenosis, but balloon can't be greater than 1 mm larger than diameter of proximal or distal vesel. Stent choice would also be the same as the adjacent vessel
