An inborn term neonate weighing 2600 g developed meconium aspiration syndrome at birth. Baby had respiratory failure requiring high-frequency oscillatory ventilation support at 15 hours of life. He additionally developed hypotension with left ventricular dysfunction noted on point-of-care echocardiography (POCE), which required dopamine and epinephrine infusions. At 28 hours of life, he was started on inhaled nitric oxide (iNO), followed by milrinone due to hypoxaemic respiratory failure and the POCE revealed severe pulmonary artery hypertension (PAH). As PAH was refractory to iNO and milrinone, vasopressin was added which resulted in rapid improvement in oxygenation and normalisation of pulmonary artery pressures. Baby was weaned off from vasoactive support in the next 120 hours. Vasopressin proved to be the rescue agent in this case of iNO refractory PAH without any side effects during therapy. Baby was successfully extubated on day 18 and was discharged with a normal neurological examination finding.

Background: Very preterm-born infants are at risk for developing bronchopulmonary dysplasia (BPD), a chronic lung disease. Nowadays, the majority of these infants reach adulthood. Very preterm-born young adults are at risk for developing pulmonary arterial (PA) hypertension later in life.

Background Tricuspid valve regurgitation is frequently overlooked by cardiologists and cardiac surgeons alike; consequently, the tricuspid valve is often referred to as "the forgotten" valve. It is the most common complication of left heart valve disease. Ring annuloplasty and suture (De Vega) annuloplasty represent two common surgical treatment techniques.

Pulmonary arterial intimal sarcoma (PAIS) is a rare malignant mesenchymal tumor often associated with an unfavorable prognosis and lacks a standardized treatment approach to date. This report presents a notable case of PAIS treated with neoadjuvant therapy involving anlotinib concomitantly administered with chemotherapy of ifosfamide and pirarubicin, which resulted in a favorable outcome. A 38-year-old man was admitted to our hospital with chest tightness, cough, and dyspnea, all of which had persisted for more than a week.

Pulmonary arterial hypertension (PAH) is a complex and progressive disease characterized by elevated pulmonary artery pressure and vascular remodeling. Recent studies have underscored the pivotal role of metabolic dysregulation and epigenetic modifications in the pathogenesis of PAH. Lactate, a byproduct of glycolysis, is now recognized as a key molecule that links cellular metabolism with activity regulation.

Background: Erdheim-Chester disease (ECD), a rare type of non-Langerhans cell histiocytosis, was classified as a haematopoietic tumour by the World Health Organization (WHO) in 2016. It involves multiple systems and is challenging to diagnose due to its broad spectrum of clinical manifestations. The pulmonary manifestations of ECD lack specificity.
