10 MORE HISTORY FROM PATIENT Seen GP few weeks ago Cough/CP/SOB/ Weight loss CT chest performed Suspicious lesion left hilum Referred to Oncology outpatient clinic ECG performed (tachycardic) Abnormal (ST Elevation) Admitted to Tamworth hospital Troponin 0.52
11 ECG IN ONCOLOGY OUTPATIENTS
12
13 CT CHEST There is a filling defect in left ventricle measuring 5.2/2.4 cm confluent left ventricular myocardium,which could represent metastasis from left hilar mass
14 Diagnosis Likely Metastatic bronchogenic carcinoma (contralateral lung, lymph nodes) Metastasis to left ventricular myocardium
15 S E C O N D A R Y T U M O R S O F H E A R T Primary Tumors rare ( 0.02% in pooled a u topsy samples) Secondary Tumors (metastasis) up 100 times higher i nci dence Intra cavitary secondary tumors unusual H ence despite their frequency, rarely gain clinical attention
16 I N C I D E N C E P r e d o m i n a n t l y o c c u r s i n 6 th o r 7 th d e c a d e o f l i f e N o s e x p r e f e r e n c e S o l i t a r y m e t a s t a s i s i s r a r e ( u s u a l l y o c c u r s i n d i s s e m i n a t e d m e t a s t a t i c d i s e a s e ) F r e q u e n c y g e n e r a l l y u n d e r e s t i m a t e d I n c i d e n c e v a r i e s f r o m s e r i e s t o s e r i e s ( a u t o p s y ) U p 2 5 % w h o d i e d o f m a l i g n a n c i e s
17 Inci dence has i ncreased during recent decades (better treatment of local disease a nd longer survival) M etastasis t o heart increasingly take i n to a ccount, H ence looked for thoroughly during postmortem examination
18
19 T U M O R S O F O R I G I N Most common tumors with metastatic potential to heart ( Lung, Breast, Oesophagus, Lymphoma, Leukemia, m elanoma) M elanomas represent highest rate of cardiac m etastasis i n m ore than half cases ( haematogenous s pread)
20 SITE OF PRIMARY AND INCIDENCE OF CARDIAC METSTASIS
21 Autopsy series Period from a u topsies were performed (25.6%)the presence of malignant tumor was diagnosed Vojnosanit Pregl Dec;62(12):
22 79 (2.7%) of these cases, m etastasis of the heart was found out Only 5 of the cases, the presence of m etastasis i n the heart was diagnosed during the lifetime M ost frequent metastases i n the heart were caused by lung cancer (18 cases)
23 In 40 (60.76%) cases, the metastasis was localized i n the m yocardium, often in the left v entricle 24 (30.38%) cases in the pericardium In 4 cases in the epi cardium In the 3 of them in the mitral a nd tricuspid v a lve.

25 S Y M P T O M A T O L O G Y Usually remain silent No correlation between extent i nvolvement and symptoms Rapid Increase in heart size due to pericardial effusion Heart failure (Obliteration heart chambers, O u tflow tract obstruction, direct myocardial i nvasion etc)
26 Arrhythmias and conduction defects Angina a nd MI (embolism/i nvasion ) Ca lung and breast m etastasize preferentially to pericardium
27 D I A G N O S I S Intracavitary Mets : Murmurs (Systolic Interference of closure of AV v a lves, Diastolic - Tumor related obstruction of left or right v entricular filling) Gallop rhythm Pericardial friction rub Diminished heart sounds
28 E C G C H A N G E S Usually Non speci fic Pericarditis rarely associated with typical S T changes Low voltage complexes and electrical a lternans VT/SVT
29 Conduction defects Q waves S T elevation i nfarction ( infiltration or displacement of myocardium)
30 X R A Y S Increase in cardiac silhouette (pericardial effusion) Pleural effusion (heart failure / Lung tumor) Large size tumors (intra cavitary) a ppear a s filling defects in radio nucleotide or contrast angiography
31 E C H O Method of choice Thickened pericardium/myocardium Pericardial effusion Pericardiocentesis and fluid analysis
32 Negative cytology does not exclude m a lignant origin Pericardial bi opsy may be necessary Large myocardial M ets ( regional wall m otion abnormalities)
33 C T A N D M R I Size and Paracardial and Transpericardial tumor growth determined more precisely Ti ssue differentiation i s possible (Solid/Liquid/Haemorragic/Fatty lesions)
