Table 1 A comparison of right/left sided myxoma
| Right-sided myxoma | Left-sided myxoma | |
|---|---|---|
| Morbidity [1,2,3,7] | ||
| Atrium | 15–20% | 75–85% |
| Ventricle | 2.5–4% | 3–4% |
| Symptoms | ||
| Obstructive | Right heart failure: systemic congestion [4]: peripheral edema, ascites, superior vena cava syndrome |
Left heart failure: pulmonary congestion: dyspnea [9] Systemic circulation ischemia: syncope [10] |
| Embolic | Pulmonary embolism [13] |
Peripheral embolism [11,12] Cerebral/mesenteric/limb ischemia |
| Constitutional | Fever, Infected cardiac myxoma, weight loss, etc. [2] | |
| Onset [14] | Late onset | Early onset |
| Treatment | ||
| Surgical resection | Timely surgical resection is always necessary for all myxomas [15,16] | |
| Prognosis | ||
| No surgery | More than 8% of patient died of myxoma associated complications [17] | |
| Surgery | Operative mortality is less than 5% [15] | |
| Recurrence | Long-term recurrence is rare [18] | |
