Who can take part

AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults having a first, stand-alone heart bypass operation for coronary artery disease in several vessels. It compares two ways of taking the left chest artery for the bypass.

Age
18 to 80 years
Sex
All sexes can join.
Disease stage
Coronary artery disease in several vessels: at least 70% narrowing of the LAD artery and at least 50% narrowing of the circumflex and right coronary areas, with or without at least 50% narrowing of the left main artery.
Earlier treatment
Must be having a first, isolated bypass operation (CABG). Previous heart surgery is not allowed.

Main reasons for not taking part

  • Emergency operation or minimally invasive bypass surgery
  • Previous heart surgery, or other heart or non-heart procedures at the same time
  • Planned bypass without the left internal thoracic artery (LITA)
  • Chronic kidney disease (GFR <60ml/min/1.73m²) or life expectancy of less than 5 years
  • Pregnancy, hyperthyroidism, or contrast agent or iodine allergy

The registry criteria, word for word

Show all 18 criteriaShow less

Who can take part

  • Primary isolated CABG patients with multi-vessel disease (defined as ≥70 % stenosis of the left anterior descending artery (LAD) and ≥50% stenosis of circumflex and right coronary territory, with or without a ≥50% stenosis of the left main artery)

Who cannot take part

  • Preoperative mediastinal radiation therapy
  • Minimal invasive coronary artery bypass surgery
  • Any concomitant cardiac or non-cardiac procedures
  • Previous cardiac surgery
  • Known contrast agent allergy
  • Severe stenosis of the left subclavian artery/ left-sided subclavian steal syndrome
  • Iodine allergy; Intraoperative exclusion criteria:
  • Chronic kidney disease (GFR <60ml/min/1.73m²)
  • Age > 80 years
  • Planned CABG without LITA use
  • Emergency operation
  • Life expectancy of less than 5 years
  • Pregnancy
  • Hyperthyroidism
  • Y/T graft off the LITA graft
  • LITA sequential grafting
  • LITA target vessel other than LAD

About the trial

What the trial wants to find out

Internal thoracic arteries can be harvested in skeletonized or pedicled technique. Latest research has posed a potential adverse effect of skeletonizing the internal thoracic arteries on graft patency rates and clinical outcome. Prospective, randomized, multi-centre trials are necessary to investigate the impact of harvesting technique of left internal thoracic artery (LITA) on graft patency rates and clinical outcome after coronary artery bypass grafting.

Read full original descriptionShow less

The HARVITA trial compares skeletonized and pedicled harvesting technique of LITA regarding graft patency rates and patient survival.

The 2 groups in the trial

  • skeletonized harvesting techniqueExisting treatment, for comparison

    In skeletonized harvesting technique, only the left internal artery itself is harvested.

  • pedicled harvesting techniqueExisting treatment, for comparison

    In pedicled harvesting technique the left internal thoracic artery, it's accompanying veins and parts of the endothoracic fascia is harvested, creating a 1-2 cm broad pedicle.

Questions to ask the study team

  1. How often do I need to come in, and for how long each time?
  2. Are travel costs paid?
  3. Can I keep my own doctor?
  4. What happens if I want to stop?
