Tricuspid valve myxoma: a rare indication for tricuspid valve repair

Robot-assisted endoscopic removal of a huge tricuspid valve myxoma: case report

Background

Cardiac myxoma is the most common benign cardiac tumor. Its tremendous size and fragile character severely bother the surgeons. Several minimal invasive approaches had been applied for radical tumor excision. The wound was forcibly enlarged for en-bloc specimen removal and prevention of debris sputtering.

Case presentation

We reported a case of huge tricuspid valve (TV) myxoma managed by robot-assisted endoscopic tumor resection and TV repair, with initial presentation of worsening shortness of breath for two months. The tumor was downsized with a morcellator and removed through a keyhole wound (1.1 cm in diameter). The patient recovered uneventfully and was discharged after four days.

Conclusions

With the first morcellator application, this might be the smallest surgical wound reported after the removal of a huge cardiac myxoma. The ICU and hospital stays were shortened. This might be effectively applied to further minimally invasive surgeries for cardiac tumor excision.

Tricuspid valve myxoma in a patient with congestive heart failure

Myxomas are the most frequent benign primary cardiac tumours (50% of benign heart tumours). This kind of tumour is most likely to be localized in the left atrium, followed by the right atrium, right ventricle and left ventricle. Quite exceptional is the presence of a myxoma originating from the tricuspid valve or from the Eustachian valve. We describe the case of a woman with moderate dyspnoea of unknown origin and the presence of tricuspid myxoma who underwent tricuspid valve curettage.

Tricuspid valve myxoma: a case report and a collective review of the literature

Tricuspid valve myxoma is extremely rare. An asymptomatic young patient discovered by chance an echogenic mass on the tricuspid valve by echocardiography, which was proved to be a myxoma. He underwent a successful myxoma resection via port-access approach. He had an uneventful postoperative course. Port-access approach is an alternative to conventional open heart surgical technique in terms of its minimally invasive purpose for myxoma resection. Moreover, it is of great importance in reducing the risk of intraoperative embolization and tumor implantation by minimizing the heart maneuver.

Myxoma involving the atrial valve chordae

Primary cardiac valve tumors are rare and comprise less than 10% of all cardiac tumors. They are, however, of clinical importance because of their unique locations. We report an unusual case of myxoma involving the tricuspid valve chordae in a young woman presenting with syncope. The myxoma was diagnosed by echocardiography and successfully removed by excision of the involved tricuspid valve chordae with valve preservation. (Curr Surg 57:357-358)

Excision of papillary fibroelastoma arising from the septal leaflet of the tricuspid valve

A case of a papillary fibroelastoma (PFE) arising from the tricuspid valve was reported. It was incidentally detected by two-dimensional transthoracic echocardiography. Prior to 1977, these tumors were exclusively found at postmortem examination. This is only the fourth reported case of a tricuspid valve PFE found by echocardiography, treated by excision, and with tricuspid valvuloplasty preserving the native valve.
