2 OUTLINE u Review the anatomy and physiology u Role of Echo 2015 u Pericardial Effusion u Pericardial Tampanade u Pericardiocentesis u Balloon pericardial window vs surgical pericardial window u Pericarditis acute, chronic recurrent management colchicine u Transient constrictive pericarditis ANATOMY 2 LAYERS: u Outer thick fibrous, blends with adventitia of Ao and PA support u Inner serous membrane (single layer of mesothelial cells (Visceral) reflects back on itself to line the inside of the fibrous layer to form (Parietal) pericardium 2

3 VASCULAR AND NERVE SUPPLY u u u u ARTERIAL SUPPLY: Pericardiophrenic Art. ( branch of internal thoracic ) VENOUS DRAINAGE: Pericardiophrenic vein SENSORY INNERVATION: Phrenic nerve VASOMOTOR INNERVATION: sympathetic trunks PERICARDIAL FLUID u Normal = 10-50ml lubricates the contact of serosal layers u Ultrfiltrate of plasma proteins, electrolytes, & phospholipids (formed in visceral pericardium) u Drains via thoracic & right lymphatic ducts 3

4 FUNCTION u Reduce friction between heart & mediastinal structures u Barrier against local spread of infection and malignancy u Constrains cardiac filling PERICARDIUM RESTRAINT Intrapericardial pressure rises rapidly as intra pericardial volume is increased acutely Rapid Slow accumul.

5 PERICARDIAL DISEASE: ROLE OF ECHO u Detection u Quantification u Hemodynamic significance u Echo guidance - pericardiocentesis PERICARDIAL EFFUSION - ECHO u The technique that probably provided the greatest impetus to the development of echocardiography in this country was the detection of pericardial effusion Harvey Feigenbaum, MD Echocardiography Lea & Febiger

6 QUANTIFICATION ECHO u M Mode, 2D, 3D u 2 D: Minimal (physiologic) normal amount of fluid in a disease free state Small (<100ml) only posterior to the LV, distal to the AV groove, & with <1cm separation of layers Moderate ( ml) circumferential, extends posterior to LA, separation of layers 1-2cm Large (>500ml) same as moderate + separation of layers >2cm, & anteroposterior or mediolateral heart swinging in sac ETIOLOGY OF PERICARDIAL INFLAMMATION u Idiopathic u Infectious: bacterial, fungal, viral, parasitic u Connective tissue disorders u Neoplasia u Metabolic Disorder u Myocardial Infarction (Dressler s) u Irradiation u Asbestosis u Trauma perforation pacemaker, AFib ablation CVD Surgical 6

7 VERY LARGE PE: SWINGING HEART Accumulation >1000ml Usually malignant Electrical alternans MALIGNANT PERICARDIAL EFFUSION u MELANOMA* u LYMPHOMA u LEUKEMIA u BREAST** u LUNG ** u ESOPHAGEAL * Tumor with highest incidence of metastasis to the heart ** Most frequent tumors seen with metastasis to heart 7

8 INDICATIONS: Pericardiocentesis: u Cardiac tamponade u Moderate to large effusion refractory to medical therapy and with severe symptoms u Suspected bacterial or neoplastic etiology Pericardial window: u Recurrent tamponade u Recurrent moderate to large effusion refractory PERICARDIOCENTESIS: ECHO GUIDANCE u Feasibility: u Approach: location size loculation subxiphoid apical u Needle location confirmation 8

9 PERICARDIOCENTESIS: ECHO GUIDANCE u Feasibility: u Approach: location size loculation subxiphoid apical u Needle location confirmation PERICARDIOCENTESIS: ECHO GUIDANCE u Feasibility: location size loculation u Approach: subxiphoid apical u Needle location confirmation 9

10 PERICARDIOCENTESIS: ECHO GUIDANCE u Feasibility: u Approach: location size loculation subxiphoid apical u Needle location confirmation Pericardial Window u Surgical window u Percutaneous Balloon pericardiotomy u Drainage time 10

11 PERCUTANEOUS BALLOON PERICARDIOTOMY u u u u 1991 Palacios proposed for recurrent malignant PE Recurrence: pericardiocentesis 13 50% subxiphoid surgical window 5% Survival not improved with surgical window Modest perioperative risk Ziskind et al JACC Vol. 21, No. 1 January 1993:1-5 PERCUTANEOUS BALLOON PERICARDIOTOMY 11

12 PERCUTANEOUS BALLOON PERICARDIOTOMY Ziskind et al JACC Vol. 21, No. 1 January 1993:1-5 Pericardial Window u Surgical window u Percutaneous Balloon pericardiotomy u Drainage time: The key to preventing recurrence is maintaining a fluid free pericardial space for a prolonged period so that autosclerosis can occur!! 12

13 TRANSIENT CONSTRICTIVE PERICARDITIS (CP) u 1987 Sagrista-Sauleda 16 pts transient form of CP resolved without surgery Etiology: collagen vascular disorder, purulent bacterial, chemotherapy u 2004 Haley et al (Mayo Clinic) pts CP/ 36 resolution of echo hemodynamic abn. without pericardiectomy most frequent etiology prior CV surgery (25%) resolution : average 8.3 wks from diagnosis TRANSIENT CONSTRICTIVE PERICARDITIS (CP) 1980 Hancock* described 2 forms of CP u Elastic or fibroelastic form represents acute or subacute phase and present with more subtle signs and symptoms u Rigid or chronic form inflammation continues > fibrosis and/or calcification * Hancock EW, Am Heart J 1980;100;
