Q

2017 Recomendation of severe secondary vs primairy MR -

  • ERO
  • Regurgitant volume
A

Some data has suggested that with severe secondary MR, a smaller ERO should be used

(? weakend ventricle, correlates with regurg volume)

Recs unchanged:

ERO: >0.4cm2 (more specific), ERO 0.2cm2 (more sensitive)

Regurg volume > 60ml

If possible, the left internal mammary artery (LIMA) should be used
to bypass the left anterior descending (LAD) artery when bypass of
the LAD artery is indicated

Class IIA

The right internal mammary artery (IMA) is probably indicated to
bypass the LAD artery when the LIMA is unavailable or unsuitable as
a bypass conduit.

77
Q

Reccomendations for use of a second IMA ?

A

IIa (B)

When anatomically and clinically suitable, use of a second IMA to graft the:

left circumflex

or

right coronary artery (when critically stenosed and perfusing LV myocardium)

is reasonable to improve the likelihood of survival and to decrease reintervention

78

less than or equal to 60 years of age with few or no comorbidities

80
Q

2011 ACC/ AHA recomendations for arterial grafting to the right

A

IIb (B) - 2011

Arterial grafting of the right coronary artery may be reasonable
when a critical (90%) stenosis is present

81
Q

2011 ACC/AHA Recomendation for the use of a RADIAL artery

A

IIb (B) - 2011

Use of a radial artery graft may be reasonable when:

grafting left-sided coronary arteries with severe stenoses (70%)

and

rightsided arteries with critical stenoses (90%) that perfuse LV myocardium

82
Q

Class III Reccomendations for using artery bypass conduit

A

An arterial graft should not be used to bypass the right coronary
artery with less than a critical stenosis (90%)

83
Q

2011 ACC AHA reccomendations for ischemic conditioning

A

II B

  1. The effectiveness of prophylactic _pharmacological_ therapies or controlled reperfusion strategies aimed at inducing preconditioning or attenuating the adverse consequences of myocardial reperfusion injury or surgically induced systemic inflammation is uncertain(182–189). (Level of Evidence: A)
  2. Mechanical preconditioning might be considered to reduce the risk of perioperative myocardial ischemia and infarction in patients undergoing off-pump CABG (190–192). (Level of Evidence: B)
  3. Remote ischemic preconditioning strategies using peripheralextremity occlusion/reperfusion might be considered to attenuate the adverse consequences of myocardial reperfusion injury (193– 195). (Level of Evidence: B)
  4. The effectiveness of postconditioning strategies to attenuate the adverse consequences of myocardial reperfusion injury is uncertain

Q

2013 ACC/AHA Broad Definition of NSTEMI Syndrome

A

clinical syndrome defined by:

Characteristic symptoms of myocardial ischemia in association with:

Persistent electrocardiographic (ECG) ST elevation

85
Q
  • 2013 ACC AHA guidelines for ST - ECG changes necessiry for STEMI Diagnosis
  • generic definition
A

ST- ELEVATION

new ST elevation at the J point in at least 2 contiguous leads

2 mm (0.2 mV) in men or 1.5 mm (0.15 mV) in women in leads V2–V3

and/or

1 mm (0.1mV) in other contiguous chest leads or the limb leads

86
Q

ST depression in 2 precordial leads (V1–V4);

A

ACC/AHA 2013 STEMI Recs

ST depression in 2 precordial leads (V1–V4) may indicate:

transmural posterior injury;

87
Q

multilead ST depression with

coexistent ST elevation in lead aVR

A

multilead ST depression with coexistent ST elevation in lead aVR

has been described in patients with-

left main or proximal left anterior descending artery occlusion .

ACC/AHA 2013 STEMI Recs

88
Q

ACC/AHA 2013

if fibrinolytics are chosen as therapy when should they be used

A

Fibrinolytics shold be given within 30 minutes of arrival to the hospital

89
Q

ACC AHA 2013 - NSTEMI

Recomendation for reperfusion therapy (interventional) in the setting of a STEMI

A

Reperfusion therapy is reasonable for patients with:

STEMI

&

Symptom onset within 12-24 h who have clinical or ECG evidence of ongoiong ischemia

90
Q

Fondaparinux

A

Fondaparinux (trade name Arixtra) is an anticoagulant medication chemically related to low molecular weight heparins. It is marketed by GlaxoSmithKline. A generic version developed by Alchemia is marketed within the US by Dr. Reddy’s Laboratories.

ACC/AHA 2011 Class III Rec: should not be used as a sole anticoagulant to support PCI

91
Q

Class I Recomendations for CABG in the Setting of STEMI

A

AHA/ACC 2013 Class 1 Rec for STEMI

  1. Urgent CABG is indicated in patients with STEMI and coronary anatomy not amenable to PCI who have ongoing or recurrent ischemia, cardiogenic shock, severe HF, or other high risk features (Level of Evidence: B)
  2. CABG is recommended in patients with STEMI at time of operative repair of mechanical defects (Level of Evidence: B)
92
Q

Level of evidence for the use of MCS in patient with STEMI

A

ACC/AHA 2013

Class IIa Reccomendation:

Use of MCS is reasonable in patients with STEMI who are hemodynamically unstable and require CABG

93
Q

New York State Criteria

Cardiogenic Shock

A

Cardiogenic Shock:

  1. episode of systolic BP < 90mmHG
  2. CI < 2.2L / min/m2

determined to be secondary to cardiac dysfunction

and

the requirment for parenteral inotropic or vasopressor or MCS (IABP, VAD, ECMO) to maintainain BP above these levels

94
Q

A

Rivaroxaban

inhibits both free Factor Xa and Factor Xa bound in the prothrombinase complex.
