Intervention in end-stage heart failure.Is it ever too late ? Can you solve my problem ?
Emergency room • 61 old man • No medical history • well until 3 weeks before intake • Progressive deterioration • fatique, cough, shortness of breath • No chest pain • At intake respiratory distress
Clinical history • Had regular check-up by GP • physically active up to 3 weeks before intake (holiday spain) • Had a good physical condition • No familial CV-history
Clinical exam • Respiratory distress • Bilateral inspiratory rales • Gallop rhythm • Congested CVP • 168 cm, 78 kg, BSA 1.87
Lab results (intake) • CRP 41 mg/l • Troponine 1.86 µg/l • CK 285 U/l (CK-MB < 0.7 %) • Lactate 2.8 mmol/l • Creatinine 1.78 mg/dl
Hemodynamics • Heartrate : 118/min • CO: 3.2 l/min (thermodilution), CI 1.71 • 95/65 mmHg • Mixed venoussaturation 42 % • (mmHg) : systolicdiastolicmean ---------------------------------------------------------------------------- • R.A. 12 • R.V. 65 18 • A.P. 63 45 50 • PCW 39 • AO 116 89 99 • LV 116 36

results • The principal outcomes occurred in 100 patients (75%). • The median duration of support was 126 days (range, 1 to 600). • The survival rate during support was 75% at 6 months and 68%at 12 months. • At 3 months, therapy was associated with significantimprovement in functional status (according to the New YorkHeart Association class and results of a 6-minute walk test) and in quality of life (according to the Minnesota Living withHeart Failure and Kansas City Cardiomyopathy questionnaires). • Major adverse events included postoperative bleeding, stroke,right heart failure, and percutaneous lead infection. • Pump thrombosisoccurred in two patients.

INTERMACS PATIENT PROFILE/STATUS LVAD 1: Critical cardiogenic shock 2: Progressive decline 3: Stable but inotrope dependent 4: “recurrent” decompensation 5: comfortable at rest but are exercise intolerant for most activity 6: able to do some mild activity, but fatigue results within minutes with meaningful physical exertion. 7: NYHA Class IIIB Partial support ?
Partial support – The concept • Pace-maker pocket • Outflow to subclavian artery • Inflow from left atrium (thoracotomy) • Cable tunneled to abdomen
Implantation LVAD • Lisinopril • Carvedilol • Spironolactone • B²-adrenergic-receptor agonist ?

CHF and CAD and no symptoms of angina • Revascularisation has not been shown to improve cardiac function or symptoms or to prevent reinfarction or death • Appealing theoretical possibilities: imaging – myocardium that is viable but not contracting normally
Asymptomatic ischemia or CCS I or II PCI - Revascularisation = reasonable class IIa (B) • Significant lesions • Suitable for PCI and high likelihood of success and low procedural risk • Vessels substending significant area of viable myocardium or be associated with ischemia on noninvasive testing
Poor LV-function CADCABG
Duke University Cardiovascular Database • EF less than 0.35 • 10-year survival CABG 46 % • 10-year survival medical therapy 27 %
Class I, level evidence: B • Significant left main coronary artery stenosis or left main equivalent • Proximal LAD with 2- or 3-vessel disease
Class III • CABG should not be performed without evidence of intermittent ischemia and without evidence of significant revascularizable myocardium
