Case 49 year old male found unresponsive outside Dunkin’ Donuts Initial presentation to ER: hypotensive, tachycardic, tachypneic Required intubation and started on pressors
Case (contd.) Past Medical History HTN End- stage renal disease on dialysis Renal cell cancer 2003 s/p R nephrectomy Found to have an abnormal echo and transferred to EMC for further management
Transthoracic Echocardiogram
On arrival to EMC: Physical Exam: BP- 92/62 (on pressors), HR-95-110 bpm Clear lungs Heart: s1, s2 regular no murmurs/rubs/gallops Ext: cold, no edema, low volume pulses EKG: anterolateral ST depressions and inferior T inversions
Transesophageal Echocardiogram
CT chest with contrast
Diagnosis Type A Aortic dissection (AoD) with intrapericardial rupture and compression of right atrium and right ventricle
Clinical course Right sided tandem heart placed for hemodynamic support Shock liver, thrombocytopenia, hemolytic anemia Questionable neurologic recovery
IMPLANTATION OF TANDEM HEART
Follow-up: After stabilization, hematoma evacuated with pericardial window & tube pericardiostomy Explant of Tandem Heart Ventricular Assist Device Currently in rehab & scheduled for aortic dissection repair
Discussion Cardiac tamponade diagnosed in 8% - 10% patients with acute Type A AoD Clinical predictor of poor outcomes and mortality Localized compression of left atrium described post cardiac surgery Rare cases of aorto-atrial fistulas Circulation 2010; 121: e266-e369
Discussion (cont.) Pericardiocentesis associated with recurrent pericardial bleeding and higher mortality Controlled pericardial drainage (10-100 ml) shown to improve blood pressure in series of 18 patients Right sided Tandem Heart: a novel approach for initial management for hemodynamic stabilization Circulation.2012; 126: S97-S101 Image: JCHF.
