The Role of Palmaris Muscle Tendon in Mitral Valve Annulus Reconstruction: A Novel Technique for Mitral Valve Repair

Abstract

PM is a suitable novel autogenous tissue that can be harvested together with the radial artery and has direct relevance in ischemic mitral valve regurgitation. These tendons can be easily utilized to achieve results similar to those of pericardial reconstruction and prosthetic annuloplasty rings. The tissue is readily available from the patient, and no extra cost is incurred. Further chemical studies in the human subjects are warranted.

Autologous Ring vs. Flexible Prosthetic Ring for Ischemic Mitral Regurgitation

“…The tissue is readily available from the patient, and no extra cost is incurred. 4 Regarding the results of echocardiographic studies in groups A and B in our study, the durability of repair decreased with time, but ring type seemed to have no influence on durability. Likewise, the number of patients in NYHA class I and II decreased over time and the number in class III increased, which may be related to a gradual increase in the degree of MR after repair.…”

“…Chronic grade 2 IMR discovered at cardiac catheterization for symptomatic coronary artery disease has a 1-year mortality rate of approximately 17%, and the 1-year mortality for grade 3 to 4 IMR is approximately 40%, which is only slightly less than that of severe MR after acute myocardial infarction. 1 7 Shuhaiber and colleagues 4 harvested and prepared the palmaris longus tendon from the forearms of 7 cadavers. The tendon was incorporated along the valve annulus.…”

“…Autogenous tissue for heart valve repair is limited to pericardium and fascia lata. 4 The aim 1). All patients had grade 2 IMR or higher.…”

Palmaris longus tendon as an autogenous expander for Brown's syndrome: A novel technique

“…PLT is used by orthopedic surgeons in a number of conditions and is one of the most common tendons used for tendon and joint reconstruction 6 ; in addition, it has been proposed for a number of uses, including eyelid ptosis repair, 7 upper lip augmentation, 8 and mitral valve repair. 9 The PLT is present in both arms in 70% and in 1 arm in 85% of the population. 6 The presence of the PLT can be confirmed by clinical examination simply by asking the patient to oppose the tip of the thumb against the little finger with the wrist flexed ( Figure 1).…”

We are not ready to use palmaris longus tendon as an autogenous expander for Brown syndrome

“…This tendon, which is not required for normal function of the hand, has been used for tendon and joint reconstruction in orthopedics, for reconstruction of lip and chin defects in plastic surgery, and for mitral valve reconstruction in cardiovascular surgery. [3][4][5] In ophthalmology, it has been used as frontalis suspension material for congenital ptosis repair. [6][7][8] Batal and Batal 2 propose that using autogenous material in patients with moderate to severe Brown syndrome would avoid the complications related to using foreign material such as silicone.…”
