In the '''orthotopic procedure''' a [[median sternotomy]] is done to expose the [[mediastinum]]. After opening the [[pericardium]], the [[great vessels]] including the superior vena cava, inferior vena cava, pulmonary artery, pulmonary vein and aorta are dissected and [[cardiopulmonary bypass]] is attached.

The donor heart is now fit onto the patient's remaining left atrium and great vessels. The transplanted heart is started after slowly weaning the patient from [[cardiopulmonary bypass]]. The procedure is completed by closing the [[chest]] cavity.

In the '''heterotopic procedure''', the diseased heart is left in place and the [[donor]] heart is implanted.

Post-operatively the patient requires [[Intensive care unit|ICU]] care. The recipient requires tailored [[Physical medicine and rehabilitation|rehabilitation]]. The duration of hospital stay depending on many patient factors including adherence to post-operative immunosuppressive[[Medication|medications]] and precautions against infections. Every patient should undergo regular general check-ups and rehabilitation sessions and be given enough emotional support. With time, the patients get more accustomed to the transplant. Compliance with [[immunosuppressant]] medication is a must to avoid the [[transplant rejection|rejection]]. Another post-operative change to expect is mild tachycardia of around 100 bpm because the [[vagus nerve]] is severed during transplantation.

Overview

Surgery is usually reserved for patients with advanced, irreversible heart failure with a severely limited life expectancy. Surgery is not the first-line treatment option for patients with heart failure. The mainstay of treatment for heart failure is medical/device therapy.

Indications

  • Surgery is the first-line treatment option for patients with either:

Systolic Heart Failure with a Left Ventricular Ejection Fraction less than 35%

[1]

  • Due to either:

Ischemic Coronary Artery Disease with Refractory Angina

  • Ischemia which is not amenable to percutaneous or surgical revascularization (coronary artery bypass graft surgery CABG) and is refractory to maximally tolerated medical and/or device therapy. [2]

Intractable life-threatening Arrhythmias

Cardiomyopathies

Congenital Heart Disease

Surgery

Pre-operative Procedure

Heart transplantation needs a donor heart from a recently deceased or brain dead donor. The transplant patient is then thoroughly evaluated for the operation. The donor heart is also evaluated to check its suitability for transplantation.

Operative Procedure

Once the donor heart has passed its inspection, the patient is taken into the operating theatre and given a general anesthetic. Either an orthotopic or a heterotopic procedure is followed, depending on the condition of the patient and the donor heart. [5]

Orthotopic Procedure

In the orthotopic procedure a median sternotomy is done to expose the mediastinum. After opening the pericardium, the great vessels including the superior vena cava, inferior vena cava, pulmonary artery, pulmonary vein and aorta are dissected and cardiopulmonary bypass is attached. The diseased heart is taken out after transecting the great vessels and a part of the left atrium. The pulmonary veins are not transected; rather a circular portion of the left atrium containing the pulmonary veins is left in place. The donor heart is now fit onto the patient's remaining left atrium and great vessels. The transplanted heart is started after slowly weaning the patient from cardiopulmonary bypass. The procedure is completed by closing the chest cavity. [6] [7]

Heterotopic procedure

In the heterotopic procedure, the diseased heart is left in place and the donor heart is implanted. The donor heart is placed in a way to have the chambers and blood vessels of both hearts connected. This results in something to the effect of a 'double heart'. In this way, the patient's original heart can be given a chance to recover. Therefore, even if the donor heart fails, it is removed to allow the patient's original heart to start working again. Heterotopic procedure is advantageous when the donor heart is not strong enough to function independently. This may be due to various reasons such as disproportionate body size of the patient and donor, the donor heart being weak, or pulmonary hypertension in the patient.[8] [7]

Post-Operative

Post-operatively the patient requires ICU care. The following are essential in a post-transplant patient:

Another post-operative change to expect is mild tachycardia of around 100 bpm because the vagus nerve is severed during transplantation.

Living organ transplant

  • In February 2006, at Bad Oeynhausen Clinic for Thorax and Cardiovascular Surgery, Germany, a 'beating heart' was transplanted into a patient.[9]
  • The donor heart is kept at body temperature and connected to a Organ Care System. This machine lets it to continue beating with oxygenated blood flowing through it. This ensures that the heart remains in a suitable condition for a longer time.
