On hospital admission, a physical examination was performed, and it revealed an obese, kyphoscoliotic person in respiratory distress, with a temperature of 37.9°C, arterial pressure of 145/88 mm Hg, and a pulse rate around 100 beat/min. She had mild lower extremity edema, and lung auscultation revealed diffused bronchospasm. There was a 3/6-holosystolic murmur in the right precordial area, and the liver was palpable and mildly enlarged. A chest radiograph showed an increased cardiac silhouette, bronchiectasis, kyphoscoliosis, elevation of the left hemidiaphragm, the absence of a left pulmonary artery shadow, and a small left hemithorax. Sinus tachycardia and incomplete right bundle-branch block were noted on the ECG. The echocardiogram revealed dilation and concentric hypertrophy of the right ventricle, whereas the left ventricle was structurally and functionally normal. Indications of severe pulmonary hypertension were also present. The left pulmonary artery main branch was not visualized. No significant findings were noted as a result of a blood test, except for a mild increase in leukocyte count. Antibiotics, bronchodilation, and oxygen administration were added to her treatment medications (which consisted of a angiotensin-converting enzyme inhibitor, furosemide, and a calcium channel blocker), and the patient’s symptoms improved after 4 days. At the same time, an investigation for secondary causes of pulmonary hypertension was programmed.
