Diagnostic catheterization for pericardial, myocardial, and pulmonary diseases

• Constrictive pericarditis: pericardial calcifications and increased diastolic pressures in all chambers with ‘dip + plateau’ shape of the pressure curve. • Cardiac tamponade: equalization of diastolic pressures in the pericardium with all cardiac chambers. • Hypertrophic obstructive cardiomyopathy: intraventricular systolic pressure gradient, small hypercontractile left ventricle (LV). • Dilated cardiomyopathy: dilated hypokinetic LV + normal coronary arteries + absence of other cardiovascular disease. • Restrictive cardiomyopathy: ‘dip + plateau’ pressure shape similar to constrictive pericarditis, but without pericardial calcifications. • Acute myocarditis: no specific finding. Acute phase–coronary angiography to differentiate it from myocardial infarction. • Endomyocardial biopsy may occasionally reveal etiology of myocardial involvement in cardiomyopathies or myocarditis. It is most frequently used in cardiac transplant recipients for the early detection of rejection. • Pulmonary hypertension: present in many cardiac disorders. Measurement of pulmonary artery pressures and pulmonary vascular resistance may be needed to decide about surgery. • Pulmonary angiography: useful in critically ill patients, brought to cath-lab for suspected myocardial infarction and found to have normal coronary angiogram.
