Ross Operation

Seoul National University Hospital

Department of Thoracic & Cardiovascular Surgery


Pulmonary autograft

Pulmonary Autograft

  • Advantages

  • Autograft is superior to the allograft in terms of clinical or hemodynamic outcomes.

  • Favorable qualities of the autograft, including

    1. Excellent immediate hemodynamics, even in small

    sizes

    2. Freedom from a need for anticoagulation

    3. Resistance to infection

    4. Suitability for use despite congenital or acquired

    distortions of cardiac anatomy.

  • Better hemodynamics over time, growth of the autograft, which has been well described and which does not occur in allografts


Pulmonary autograft1

Pulmonary Autograft

  • Idea of choice

  • The Ross procedure is not a cure for aortic valve disease.

  • Beyond its technical demands, which are formidable, there are legitimate concerns about long-term growth and durability of the autograft, dilatation of the neoaortic root, and fate of the pulmonary allograft.

  • Ultimately, the decision to perform the Ross procedure or an alternative operation must be tempered to some degree by what that alternative operation is.


Pulmonary autograft2

Pulmonary Autograft

  • Aortic root tailoring

  • Aim

    1 To overcome the size mismatch (2mm over sized)

    • Adjust aortic anulnus to 2mm smaller than that

      of the pulmonary autograft

  • Method

    1 Circumferential strips

    • Purse-string sutures around the annular

    • Noncircumferential removal of tissue posteriorly

      at the level of anterior leaflet (Triangular excision

      between left & noncoronary cusp)


Aortic root replacement

Aortic Root Replacement

  • Use of allograft

  • I. Advantages

  • 1. Simplicity

  • Younger patient

  • 1) Annulus is large & noncoronary cusp is deep.

  • 2) Commissures may not be symmetric.

  • 3) Sinuses may have variable diameter.

  • 4) Transverse orifice in a bicuspid valve

  • 2. Decrease in structural degeneration over time

  • II. Principles

  • 1. The allograft should not be made to fit the host.

  • 2. The allograft valve should maintain its inherent symmetry.

  • 3. The size of the allograft becomes less critical.


Pulmonary autograft3

Pulmonary Autograft

  • Causes of failure

  • Technical errors during dissection and

    implantation of pulmonary autograft

  • Geometric mismatch between the two

    semilunar valves

  • Late endocarditis

  • Immunologically mediated injury

  • Structural changes in the autograft that predispose to dilatation of the autograft


Ross procedure

Ross Procedure

  • Disadvantages

  • Technical demands, which are formidable

  • Legitimate concerns of long-term growth

  • Durability of the autograft

  • Dilatation of the neoaortic root

  • Fate of the pulmonary allograft


Ross procedure1

Ross Procedure

  • Contraindications

  • The pulmonary valve may be congenitally absent or deformed

  • The pulmonary valve may be damaged by acquired disease, or compromised by previous surgical procedures

  • Certain connective tissue disorders, such as Marfan syndrome, probably affect pulmonary valve & disqualify it from consideration


Ross procedure2

Ross Procedure

  • Factors of late results

  • Cellularity of the semilunar valve decreases with age,

  • Ross operation may not be appropriate for elderly.

  • Adjust diameter of the aortic annulus and of the

  • sinotubular junction to those diameters of the

  • pulmonary autograft

  • Pulmonary homograft is more durable than the aortic

  • homogaft

  • Neither the diameter of aortic annulus, nor sinotubular

    junction should exceed the length of the free margin

    of the leaflet


Ross procedure3

Ross Procedure

  • Arrhythmia

  • 1. Underlying potential for ventricular arrhythmia

  • because of pressure & volume overload

  • 2. Damage the septal branches of the LAD causes

  • myocardial ischemia & ventricular ectopy

  • 3. Coronary artery transfer may lead to the areas of

  • myocardial ischemia & rhythm abnormalities.

  • 4. Annular-enlarging procedures or muscle resection

  • in subaortic area damage the conduction system.

Ross-Konno Procedure

  • Widened Interventricular Septum (Ventriculoseptoplasty)

  • Subaortic left ventricular outflow tract is augmented by

  • a patch which closes created ventricular septal defect
