Cardiac myxoma arising from the inferior vena cava

Area of Science:

• Cardiovascular Surgery
• Cardiac Oncology
• Vascular Surgery

Background:

• Cardiac myxomas are typically found in the left atrium, but rare cases can originate in the inferior vena cava.
• Inferior vena cava myxomas pose a surgical challenge due to potential interference with venous cannulation for cardiopulmonary bypass.
• Previous approaches for managing such cases include direct inferior vena cava or femoral vein cannulation.

Purpose of the Study:

• To present a case of inferior vena cava myxoma.
• To evaluate the safety and efficacy of routine right atrial cannulation for cardiopulmonary bypass in managing this rare condition.
• To demonstrate the feasibility of complete tumor resection using this approach.

Main Methods:

• A case report detailing the surgical management of a patient with an inferior vena cava myxoma.
• Utilized standard right atrial cannulation for cardiopulmonary bypass.
• Performed surgical resection of the tumor mass.

Main Results:

• Routine right atrial cannulation was successfully achieved.
• The approach provided adequate exposure for complete resection of the myxoma.
• No intraoperative or postoperative complications related to cannulation were observed.

Conclusions:

• Right atrial cannulation is a safe and effective strategy for cardiopulmonary bypass in patients with inferior vena cava myxomas.
• This technique facilitates complete resection of the tumor.
• It offers an alternative to less conventional cannulation methods in rare cardiac tumor cases.
