Q

Effect of Proshesis-patient mismatch on long-term survival with aortic valve replacement: assessment to 15 year

Jamieson WR, Ye J, Higgins J, Cheung A, etc..Lichtenstein SV
Annals of thoracic surgery 2010 Jan;89 (1) 51-8

A

Controversy exists as the predictors of mortality after AVR and influence of PPM

Between 1982-2003 in just over 3000 pts this group from Vancouver showed at 15 year survival that PPM is not a predictor after AVR regardless of EOAi

This was adjusted when Ejection fraction was > 50%. Also, there did appear to be a worsening outcome in those with a severe EOAi (so this might be a bad omen)

CORONARY study: Off-pump or on-pump coronary artery bypass grafting at 30 days

NEJM 2012 April 19

A

70 centers in 10 countries
4752 patients in whom CABG was planned to undergo the procedure off-pump or on pump.

Primary outcome was composite of Death, Nonfatal stroke, nonfatal MY, or new renal failure requiring dialysis at 30 days.

There was no significant difference in rate of primary outcome between off and on-pump 9.8% vs 10.3%).

Off pump was associated with significantly reduced rates of blood-product transfusion (50.7% vs 63%), acute kidney injue 28 vs 32%) and respiratory complication (5.9% vs 7.5%) but increased rate of revasculaizations 0.7% vs 0.2%.

Patients with at least one such lesion (n=888) were randomized to either PCI or optimal medical therapy
The primary end point of the study was a composite of death, MI, or urgent revascularization.

Mean f/u was 71. +/- 4.5 years
Freedom from autograft reintervention was 87% at 10 years and 83% at 12 years

The risk for reoperation depends on the utilized techqniue. The subcoronary Ross technique appears to result in superior durability.

Risk of late aortic events after an isolated aortic valve replacement for bicuspid arortic valve stenosis with concomitant ascending aortic dilation

Evaldas, (Borger) EJCTS 2012;42(5) 832:838

A

Instiutional database of 153 BAV with stenosis and concomitant ascending aortic dilation of 40 to 50mm who underwent isolated AVR from 1995 to 2000. mean age was 54

Follow-up was 100% complete. Mean follow-up was 11.5years +/- 3.2 years. Survival rates of 86 and 78% at 10 and 15 years. Ascending aortic surgery was required in 5 patients (For progressive aortic aneurysm).

Freedom from aortic interventions at 10 and 15 years was 97 and 94% for the AS group (slightly lower for the AI group 88 and 70% at 10 and 15 years).

Suggest that BAV with AS and mild to moderate ascending dilation are at considerable low risk for adverse events at 15 years. BAV phenotype should be considered.

No difference in composite all cause mortality and non-fatal MI
No difference in ACS hospitalization

Q

What is re-LY trial

A
150 mg of Dabigatran
	significantly lower rate of stroke and embolism
	similar rate of major bleeding
110 mg of Dabigatran
	similar rate of stroke and embolism
	lower rates of major bleeding
Both doses
	significantly reduced risk of intracranial hemorrhage
	increased risk of GI bleeding
	dyspepsi most common side effect
55
Q

What are details of raps

A

Initially 500+ pts but only 234 for 7.7 year follow-up
Overall rates of complete occlusion 18% for SVG and 9% for radial artery
Functional graft occlusion 12. 3% for radial and 19.9% for SVG

This was performed in 9 centers, 3VD, had to have high grade stenosis in left circumflex and right.

56
Q

Endocarditis–Early vs delayed surgery “EASE”

A

Randomized trial showing that early surgery is better than conventional therapy for patients with left-sided infective endocarditis

only patients with infective endocarditis and severe mitral-valve or aortic-valve disease and vegetation with a diameter greater than 10 mm.

primary end point of in-hospital death plus embolic events within six weeks of randomization (3% vs 23%, hazard ratio 0.10; p=0.03).

57
Q

Mayo clinic 2008 JTCS

A symptomatic AS, evolution

A

Freedom from OR/Sx/death at 5 yr is 50%

58
Q

Sievers classification

More frequent type?

A

Type depend on number of raphe
Then precise fusion
Then precise function S or I

More frequent is 1 raphe, left-right fusion and stenotic

So type 1, L-R , S

59
Q

ElKhoury classification of AI

Best result after repair ?

A
Type 1 Normal,leaflet motion
    A dil STJ
    B dil STJ and sinus
    C dil AVJ
    D perforation

Type 2 excess motion

Type 3 restriction

Best result after repair with type 1 and 2

60
Q

Canadian experience with TAVI

A

30 d mortality 10%
1 yr mortality 22%

Stroke 2,5 %

Risk factor of death
COPD
Renal
Pulmonary hypertension

Q

Ross Toronto 15. Yr

A

Survival 97%

Freedom from
   Reop
      Auto 92%
      Homo 97%
      Any 85%

Risk factor for reop
IA
Male
Annulus > 27

62
Q

ACEI in CABG

A

Preop increase mortality, inotropes need, renal insufficiency, AF

Postop
Quovadis (pt CHF, HBP, MI) reduce ischemic event
APRES (pt EF 30-50) reduce MI, death, CHF
IMAGINE : no benefit in low risk patient

63
Q

Aspirin and CABG

A

Postop
MANGANO trial reduce death, MI, stroke, renal ins., bowel infarct

Preop
Reduce death without increasing bleeding or transfusion

64
Q

Beta blockers in CABG

A

Mortality benefit for everybody

Also reduces AF

65
Q

Statin in CABG

A

Reduce mortality, ischemic events and repeat revasc

Also reduces atherosclerosis in grafts

66
Q

BARI

A

CABG vs bms
Overall mortality and MI : no difference
Subgroup diabetes : advantage CABG

Bari2d (only diabetes)
Meds vs revasc ( CABG or pci)
Reduce MACE in cabg vs meds but not pci vs meds
