20 Distinguishing Intra-Cardiac Masses Characteristic Thrombus Tumor Vegetation Location LA (esp. if enlarged or MV disease) LA (myxoma) Myocardium Pericardium Valves Usually valvular Occasionally on ventricular wall or Chiari network LV ( EF or segmental WMA) Appearance Usually discrete and somewhat spherical or laminated against LV apex or LA wall Various: may be circumscribed or irregular Irregular shape, attached to proximal side (upstream) of the valve with motion independent from the valve Associated findings Underlying etiology usually evident Intracardiac obstruction depending on site of tumor Valvular regurgitation usually present LV systolic dysfxn or segmental WMA Fever, systemic signs of endocarditis, positive blood cultures MV disease with LAE

25 INTRODUCTION Primary tumors are rare % to 0.19% post mortem. 75% - benign 40% are myxomas Most tend to be asymptomatic and have no specific symptoms or signs. Aoyagi S, Right Atrial Myxoma in a Patient Presenting with Syncope Kurume Medical Journal Vol 51, No 1, 2004

27 MYXOMA 20% RA 5% Multicentric 75% Most arise from the interatrial septum at the border of fossa ovalis LA Ragland M, The Role of Echocardiography in Diagnosing Space-Occupying Lesions of the Heart, Clinical Med & Research, Vol 4, No 1: 22-32

30 SIGNS & SYMPTOMS The clinical feature of masses are determined by their location, size and mobility.

34 Right Atrial Myxoma Uncommon Accounts for only 20% of all myxomas Usually arises from the inter-atrial septum Polypoid Pedunculated Patrianakos A, Right Atrial Myxoma: Echocardiograhic Apperance Euro Jour of Echo ,

35 51/M Progressive dyspnea on exertion TTE: large RA mass prolapsing through the tricuspid valve into the right ventricle Case Reports Discharged AMA Died about one hour after getting home while trying to stand up from the sitting position. Ojji D, A probable right atrial myxoma prolapsing through the tricuspid valve into the Righr ventricle: a case report, Cases Journal 2008, 1:386

36 62/F Syncope TTE: large right atrial mass prolapsing through the tricuspid valve into the right ventricle Underwent open heart surgery with excision of myxoma Case Reports Aoyagi S, Right Atrial Myxoma in a Patient Presenting with Syncope Kurume Medical Journal Vol 51, No 1, 2004

37 Right Atrial Myxoma The atrial mass was found to prolapse through the tricuspid valve into the right ventricle. Complete obstruction of the tricuspid valve which resulted can result to syncope and sudden death. Commonest cause of death in right atrial myxoma especially when it extends to the tricuspid valve. Patrianakos A, Right Atrial Myxoma: Echocardiograhic Apperance Euro Jour of Echo ,

38 Role of Echocardiography Can provide both anatomic and physiologic information about the mass. Availability Real time images Noninvasive Relatively inexpensive Serial studies Ragland M, The Role of Echocardiography in Diagnosing Space-Occupying Lesions of the Heart, Clinical Med & Research, Vol 4, No 1: 22-32

39 Role of Echocardiography The use of 2 D echocardiography was useful for determining the sites of the tumor stalks and for the choice of surgical treatment. Watanabe K, Usefulness of 2-D Echocardiography for Diagnosis of the Sites Of Origin in Myxoma, TJM, 1983, 139,

41 BENIGN vs MALIGNANT Benign Common Asymptomatic Heterogenous Minimal Calcifications Attached to IAS Mobile Malignant Rare Symptomatic Homogenous (+) Calcifications Invasive Fixed

42 Manifest in the heart: mass, pericardial disease or myocardial involvement METASTATIC Tumor spread to heart: direct invasion, hematogenous spread

45 Surgery Speedy growth of the tumor Risk for embolization Blocking the valve orifice Butany J, Cardiac Tumors: Diagnosis and Management Lancet Oncol 2005;

46 TREATMENT Treatment is surgical with en bloc resection including rim of septum around base. Recurrence in about 1-5% of cases (incomplete resection, implantation from first tumor etc) - therefore annual surveillance recommended. Butany J, Cardiac Tumors: Diagnosis and Management Lancet Oncol 2005;

47 TREATMENT Patients with cardiac metastases can undergo palliative debulking. Radiotherapy } Chemotherapy Very few data Butany J, Cardiac Tumors: Diagnosis and Management Lancet Oncol 2005;

48 In our patient... 68/M with HCC Incidental finding of isolated sporadic right atrial mass (Myxoma) Open heart surgery (atrial mass excision) GI and Oncology referral

49 Key Points Primary Cardiac tumors are rare and usually benign. Clinical presentation based on location and size of mass. Echo (TTE and TEE) remains the initial and reliable imaging test. Treatment usually involves surgery for tumors.
