UNLABELLED Unilateral pulmonary artery agenesis without any cardiovascular malformation is a rare anomaly. We present the imaging findings of a patient who was diagnosed as isolated left pulmonary artery agenesis. A 27-year-old female patient was admitted to our hospital due to dyspnea during exercise for five years. Chest X-ray revealed minimally small left pulmonary hilum and left lung. She w...

Chronic pulmonary hypertension in humans is characterized by shortening of the pulmonary artery acceleration time as measured by Doppler echocardiography, such that the higher the pulmonary artery pressure, the shorter the pulmonary acceleration time. Increases in heart rate are also known to produce decreases in the pulmonary artery acceleration time. To explore the relationship between mean p...

OBJECTIVE We evaluated the efficacy of the early rehabilitation of remnant pulmonary artery in unilateral absent intrapericardial pulmonary artery and the factors affecting pulmonary artery growth. METHODS We retrospectively reviewed the medical records and imaging modalities of 15 patients with unilateral absent intrapericardial pulmonary artery (7 left and 8 right; median age at diagnosis, ...

BACKGROUND Pulmonary arteries are not just affected by thrombus. Congenital and acquired conditions can also involve the pulmonary arteries. An awareness of these conditions is important for the radiologist interpreting chest computed tomography (CT). METHODS The anatomy of the pulmonary arteries was reviewed. CT and magnetic resonance (MR) acquisition protocols for imaging the pulmonary arte...

BACKGROUND The nasal septal deviation (NSD) is one of the major causes of nasal obstruction. This condition increases upper airway resistance. In This study we evaluated the mean pulmonary artery pressure (MPAP) in patients with markedly deviated septum. METHODS Sixty two patients with NSD (Age range: 26-45 years, 34 men and 28 women) were included in the study. Mean pulmonary artery press...

W hile the seminal advance in the treatment of pulmonary artery hypertension (PAH) over the past 2 decades has been pharmacological targeting of dysfunctional endothelium-derived pathways that contribute to the characteristic vascular remodeling of this condition irrespective of etiology (1), several novel interventional techniques have also been useful in selected patients. Atrial septostomy, ...

BACKGROUND The aim of this study was to investigate the feasibility of main pulmonary artery diameter quantification by thoracic computerized tomography (CT) in the diagnosis of pulmonary hypertension seconder to biomass smoke exposure. MATERIAL AND METHODS One hundred and four women subjects with biomass smoke exposure and 20 healthy women subjects were enrolled in the prospective study. The...

We experienced the surgical repair of an extremely rare pulmonary artery dissection without pulmonary hypertension. The patient had multiple coronary-pulmonary artery fistulae, which presumably caused pulmonary artery dissection. The surgical treatment included the closure of the multiple coronary fistulae and the resection of the intimal flap in the main pulmonary artery. The patient recovered...

Coronary Artery To the Editor: The echocardiographic images of the anomalous origin of the left coronary artery from the main pulmonary artery presented by Lin et al1 are very instructive. But I disagree with the statement the authors made in the legend of their Figure 3 that “Turbulent flow from the main pulmonary artery through the orifice to the left coronary artery is evident.” In anomalous...
