Title: Remote Ischaemic Preconditioning for Heart Surgery
Brief Summary: The purpose of this study is to evaluate the effects of Remote Ischaemic Preconditioning on perioperative ischaemic injury in patients undergoing cardiac surgery compared to control intervention.


Options:
A: Inclusion Criteria:

* perimembranous or muscular outlet or muscular inlet ventricular septal defect
* pulmonary hypertension (+)
* infant (\<1 year)

Exclusion Criteria:

* subarterial ventricular defect
* chromosomal defect
* airway or parenchymal lung disease
* blood disorder
* anticipation of cardiac muscle resection
B: Inclusion Criteria:

* Significant ischemic stroke suspicion (NIHSS 1-24) and paresis of an extremity.
* Treatment with rtPa within 4.5 hours from debut of symptoms.
* Age above 18 (changed from 01.01.2010 to no upper age limit)
* Independent in daily living before the acute onset of symptoms. (mrs\</=2)
* MR scan showing DWI lesion, consistent with acute ischemic stroke.

Exclusion Criteria:

* Contraindications for iv rtPA
* Onset of symptoms older than 4.5 hours
* Previous diseases of the brain: Intracranial aneurisms or arteriovenous malformations. Brain surgery or hemorrhagic stroke. Former ischemic stroke within the last 3 months.
* Heart diseases: Infectious endocarditis or suspicion of septic emboli, pericarditis, ventricular thrombosis, aneurisms of the heart wall or major heart failure.
* Serious diseases: Cancer, AIDS, dementia, significant abuse, renal failure, liver diseases such as liver failure, cirrhosis, portal hypertension, active hepatitis.
* Pregnancy
* Major ischemic stroke where the patient is unconscious.(NIHSS \> 25).
* Symptoms suspect for migraine, Multiple sclerosis, TIA or another neurological disease than ischemic stroke.

MR scan:

* Contraindications for MRI scans
* Tumor cerebri, cerebral abscesses
* Known hypersensitivity to Gadovist or any of its ingredients, acute or chronic severe renal impairment (GFR \< 30 ml/min/1.73m2), acute renal insufficiency of any severity due to the hepato-renal syndrome or in the perioperative liver transplantation period.
* Caution with using Gadovist to patients with severe cardiovascular disease, and only to be used after a risk-benefit assessment.
* Caution with using Gadovist in patients with low threshold for seizures.

Lab data:

* Blood glucose \< 2, 8 mmol/l or \> 22 mmol/l
C: Inclusion Criteria:

* Subject age birth (\>36 weeks gestation) to 17 years.
* Underlying cardiac anatomy and planned primary repair with no anticipated residual shunting. Repair must necessitate use of cardiopulmonary bypass.
* Informed consent/assent of subject, parent(s) or legal guardian as appropriate.

Exclusion Criteria:

* Current or recent ischemic insult, defined as vascular occlusion or episode of cardiorespiratory collapse requiring medical intervention occurring within 7 days of enrollment.
* Evidence in any system for organ dysfunction that requires medical intervention.
* Current treatment with systemic anticoagulation therapy or the presence of a bleeding diathesis.
* Presence of important pulmonary or airway disease requiring medical intervention.
* Current or previous (within 10 days of screening) use of systemic corticosteroids.
* Recent (within 7 days of screening) or current documented systemic infection or sepsis.
* Anticipated unavailability of an uninstrumented limb with no anatomic or physiologic abnormality precluding administration of RIPC stimulus using a standard blood pressure cuff.
D: Inclusion Criteria:

* patients undergoing heart surgery on cardiopulmonary bypass

Exclusion Criteria:

* age \< 18
* Emergency cases
* left ventricular ejection fraction less than 30%
* current atrial fibrillation
* Inability to give informed consent
* preoperative use of inotropics or mechanical assist device
* severe liver, renal and pulmonary disease
* recent myocardial infarction (within 7 days)
* recent systemic infection or sepsis (within 7 days)
* severe stroke (within 2 months)
* peripheral vascular disease affecting upper limbs
* previous serious psychiatric disorders (e.g. schizophrenia, dementia)
* concomitant carotid endarterectomy
* rare surgeries: cardiac transplantation, correction of complicated congenital anomalies, pulmonary thromboembolectomy, off-pump surgery, minimal-invasive operation without sternotomy
