Oneof the severe conditions in the contemporary society is heartfailure. The hearts of victims having such complications are unableto supply blood that can adequately cater for the normal bodyfunctioning. The condition will always make a person feel tired oftenand unable to perform even the simple daily tasks. Medications haveproved to be useful in the treatment of the heart failure. In caseswhere medications fail to realize the goal, heart transplant hasalways been the last resort. Unfortunately, the approach isunsuitable for some individuals like the aging patients. Theinnovation of the Ventricular Assist Device (VAD) has brought lightto the dark times the patients were experiencing. VAD is arguably themost significant innovation in addressing heart complications despitesome of the minor risks that it exposes to the patients.

VentricularAssist Device (VAD)

Thedevice is a mechanical pump that supports the heart functioning andblood flow in individuals with failing hearts (Mohite et al., 2014).It is inserted in the chest and drives blood from the lower heartchambers to all parts of the body. It can be used temporarily tosupport the heart or as a permanent solution to the complications.Since it relieves the overall workload of the heart, it prolongs thelife of the patient. Besides, it also relieves the symptoms like lowenergy and losing breathe. Patients gain the strength to carry outrigorous exercises, go back to work or even recover fully and avoid atransplant.

  1. Types and Parts of the VAD

TheFood and Drug Administration approved various types of VADs. The mostcommon type is the LVAD. This form assists the left ventricle of theheart. Nevertheless, there are other kinds like RVADs which aids theRight ventricle and the Bi-ventricle which deals with both chambers(Grosmon-Rimon et al., 2016).

AllVADs are made up of several parts. First, there is a small tubelinked to the heart that takes blood to the pump (Rojas et al.,2015). The pump is either external or at times in the chest. Anothertube connects the pump to the aorta which is the main blood supplierin the body. Then there is a control system worn outside togetherwith a source of power.

  1. Recommended Situations for the Device

Thefirst situation is when one is waiting for a transplant. In suchcases, there is temporal implantation of the equipment for the periodthat the person will be waiting for a heart donor. This temporarycondition is known as bridge therapy (Schimitto et al., 2016).

Anothercondition termed as the destination therapy is when the individual isnot legible for transplant. The last part is to give the heart timeto recover from illnesses, surgery or attacks.

  1. Procedure

Severaltests like blood tests, chest x-rays among others are carried outbefore the process to ensure that the patient is healthy (Hernandezet al., 2015). Its implantation calls for an open-heart operationunder anesthesia. It takes approximately four to six hours. Afterthat, the patient is transferred to the intensive care unit torecover.


Itis evident that VADs are the only alternative in case all thepossible solutions fail to work or are ineligible to a particularpatient. The equipment is not a replacement for the heart but rathersupports the heart. The survival rate of patients using VADs hasskyrocketed off late, and it is almost approaching the levels ofthose who went through heart transplants. Patients need to check itdaily and make sure that it is properly functioning.
