❑ Classic triad of:
❑ Kussmaul sign
❑ Pulsus paradoxus
❑ Tricuspid regurgitation murmur
❑ Atrioventrcicular dissociation
❑ Vagal symptoms:
- ❑ Bradycardia
- ❑ Nausea
- ❑ Vomiting
- ❑ Diaphoresis
- ❑ Pallor
❑ RV dilatation
❑ Depressed RV systolic function
❑ RV wall akinesia or dyskinesia
❑ RA enlargement
❑ Elevated pulmonary pressures
❑ Pulmonary regurgitation
❑ Tricuspid regurgitation
❑ Increased right atrial pressure
Gold standard diagnostic modality
❑ In the majority of RVMI:
- ❑ The culprit artery: Proximal RCA
❑ Occasionally:
- ❑ The culprit artery: Left circumflex artery or left anterior descending artery
❑ Hemodynamically significant RVMI:
- ❑ Increased RAP>10 mmHg
- ❑ RAP to PCWP ratio >0.8 (normal<0.6)
- ❑ RAP within 5 mmHg of the PCWP
- ❑ Reduced cardiac index
- ❑ Disproportionate elevation of right-sided filling pressures: Hallmark of RVMI
❑ In concomitant LV dysfunction:
❑ Additional hemodynamic changes:
- ❑ Prominent [[Y-descend of the RAP
- ❑ Drop of the systemic arterial pressure >10 mmHg with inspiration
- ❑ "Dip and plateau" morphology and equalization of the diastolic filling pressures
