18. Pulmonary artery pressure monitoring: Measures pressure in the pulmonary arteries.
19. Exercise oximetry: Measures oxygen levels during physical activity.
20. Radionuclide ventriculography: Evaluates heart function and blood flow using radioactive tracers.

Treatments:

Treatment for Non-Aneurysmal Stenosis in the Right Pulmonary Artery aims to alleviate symptoms, improve quality of life, and prevent complications. Here are thirty common treatment options:

1. Medications: a. Blood thinners (anticoagulants) to prevent clot formation. b. Vasodilators to relax and widen blood vessels. c. Diuretics to reduce fluid buildup. d. Beta-blockers to slow heart rate and lower blood pressure. e. Anti-inflammatory drugs to reduce inflammation. f. Oxygen therapy to improve oxygen levels in the blood. g. Antibiotics to treat infections. h. Immunomodulators to regulate the immune response. i. Pulmonary hypertension-specific medications.
2. Lifestyle modifications: a. Quitting smoking. b. Regular exercise within recommended limits. c. Maintaining a healthy weight. d. Following a heart-healthy diet low in sodium and saturated fats. e. Managing stress. f. Avoiding exposure to environmental pollutants or allergens.
3. Pulmonary rehabilitation: Structured programs involving exercise, education, and support to improve lung function and overall well-being.
4. Oxygen therapy: Supplemental oxygen delivered through nasal prongs or a mask to increase oxygen levels in the blood.
5. Surgical interventions: a. Pulmonary artery angioplasty: Inflating a balloon in the narrowed artery to widen it. b. Stent placement: Inserting a small metal mesh tube to keep the artery open. c. Thrombectomy: Surgical removal of blood clots from the pulmonary arteries. d. Pulmonary artery bypass surgery: Creating a new pathway for blood flow to bypass the narrowed artery. e.
