Cardiovascular Trauma • Trauma: 4th leading cause of death in US. • CV Trauma: Exact incidence is Unknown. • Penetrating: 6% of 1200 were alive. • Males (15 – 35)
50% die rapidly before arival. • Chambers mostly involved: RV LV RA LA
Chamber penetrated • Pericardial involvement.
Blunt Cardiac Injury. • Direct: • Indirect: Pressure on Abdomen. Automobile Accidents.
Myocardial Contusions • Histologic diagnosis. • No definitive clinical criterias. • Arrythmias/ Heartfailure/ Sudden death. • Coronory arteries: Occlusion, laceration , fistuala • IV septal rupture, Myocardial Aneurysm or Pseudoaneurysm • Atleast 24 hour EKG monitoring in stable pts.
Chamber or Vessel laceration. cardiac trauma-chamber rupture
Injury to Aorta • Rupture of Arota • 8000 cases/year in USA • Rapid deceleration injury. • 20% pts who die of MVA. • 80 -90% fatal • Location • Partial rupture • Pseudoaneurysm • Fistulas. • TEE/CT
Iatrogenic Injury • CPR Rib fx LV/RV rupture. • Rupture of • pappilary muscles • Aorta • Penetrating : • RV biopsy • Pacemakerwires.
Iatrogenic Injury • Coronory Angio/PTCA • Arota or coronory ostial dissections • Coronory artery rupture. • IABP • Dissection • Thromboemboli. • Indwelling venous catheters/Swans. • Pulmonary artery perforations.
Diagnosis. • Index of suspicion. • Absence of visible injuries • Absence of enzyme leak • ABCD/Signs of Tamponade/Shock • EKG • Enzymes • Echo/TEE
Signs of Tamponade • Hypotension • Pulsus Paradoxus • kussmaul's sign
