Pulmonary hypertension is defined as a mean pulmonary arterial pressure ≥25 mmHg. We focus on its relevance in congenital heart disease, reviewing pathophysiology, diagnosis and management. Pulmonary hypertension is a relatively common complication of congenital heart disease, with adult prevalence between 5 and 10%. A multifactorial cause is recognized, relating to the size and nature of cardiac defect as well as environmental and genetic factors. More complex disease is increasingly recognized rather than pure Eisenmenger complex...

OBJECTIVES: To evaluate the ability of chest computed tomography (CT) to predict pulmonary hypertension (PH) and outcome in chronic heart failure with reduced ejection fraction (HFrEF). METHODS: We reviewed 119 consecutive patients with HFrEF by CT, transthoracic echocardiography (TTE) and right heart catheterization (RHC). CT-derived pulmonary artery (PA) diameter and PA to ascending aorta diameter ratio (PA:A ratio), left atrial, right atrial, right ventricular (RV) and left ventricular volumes were correlated with RHC mean pulmonary arterial pressure (mPAP) ...

The patient was a 66 year-old male. Computed tomography (CT) angiography showed a huge aneurysm(120 mm) in the aortic arch and chronic type B aortic dissection(45 mm) in the descending aorta. Echocardiography showed patent ductus arteriosus( PDA). Because of pulmonary hypertension due to PDA, it was considered unacceptable to put him under general anesthesia twice. We performed thoracic endovascular aortic repair (TEVAR) via the ascending aorta and total arch replacement (TAR) simultaneously to prevent paraplegia...

BACKGROUND: We evaluated the feasibility of perfusion SPECT/CT for providing quantitative data for estimation of perfusion defect extent in chronic thromboembolic pulmonary hypertension (CTEPH). METHODS: Thirty patients with CTEPH underwent Tc-human serum albumin lung perfusion SPECT/CT. Perfusion defects were quantified using 3 different methods: (1) visual, semiquantitative scoring of perfusion defect extent in each lung segment, (2) threshold-based segmentation of perfused lung volumes, and (3) threshold-based segmentation of perfused lung volumes divided by segmented lung volumes at CT (perfusion index)...

Pulmonary hypertension is a serious condition with multiple underlying aetiologies which require different treatment strategies. We present a case of severe idiopathic pulmonary arterial hypertension in a 20-year-old patient with ongoing breathlessness. She was initially diagnosed with asthma and panic attacks in community care. As the symptoms became progressively worse, she was referred for pulmonary hypertension clinic assessment. Ventilation/perfusion single-photon emission computed tomography (V/Q SPECT) showed grossly abnormal perfusion defects which were mismatched to the ventilation scan, suggestive of chronic thromboembolic disease...

A 64-year-old Latin American woman was referred for evaluation of an incidental pulmonary nodule. She had originally presented to her primary care physician with complaints of abdominal pain warranting a CT scan of the abdomen, which revealed a right lower lobe pulmonary nodule. She denied any complaints of shortness of breath or cough. Review of systems was unremarkable and medical history was significant for hypertension only. She also denied primary or secondary tobacco exposure or any recreational drug abuse...

Sarcoidosis is a granulomatous disease of unknown cause, occurs worldwide and has a highly variable prevalence. The disease is typically dominant in the lungs, although it can affect virtually any organ and is unpredictable in its clinical course. The severity of pulmonary sarcoidosis ranges from incidentally discovered radiographic abnormalities in asymptomatic patients to a chronic progressive disease that is refractory to treatment. Mortality from sarcoidosis appears to have increased in the past three decades, with respiratory failure being the most common cause of sarcoidosis-related death...

Pneumocystis carinii pneumonia is a rare disease in dogs. It is primarily reported in cavalier King Charles spaniels and miniature dachshunds with suspected underlying immunodeficiency. This case series reports the findings in five dogs (four cavalier King Charles spaniels and one Bedlington terrier) with confirmed P. carinii pneumonia. Thoracic (CT) revealed ground glass opacity of the pulmonary parenchyma with a diffuse or multifocal distribution. The severity of this pattern was variable. Less consistent imaging findings included parenchymal bands, bronchial dilation and signs consistent with pulmonary hypertension...

Occurrence of paradoxical arterial embolism may cause the first symptoms in patients with a coexisting hypercoagulable state and patent foramen ovale (PFO). This can result in significant morbidity and mortality depending on the location of the embolism. The risks and benefits of closure of small PFOs have not been well elucidated in prior studies. We describe a patient with a history of Factor V Leiden heterozygosity who presented with left arm pain secondary to arterial embolism. The patient was a 51-year-old male who initially presented to the emergency department after awaking from sleep with progressive, severe, burning left arm pain...

Persistent iatrogenic atrial septal defects (iASDs) can be observed after intervention requiring a left atria (LA) access, including pulmonary vein isolation (PVI) of atrial fibrillation (AF). We investigated the incidence of iASDs post-second-generation cryoballoon ablation and the pre-procedural predictors. Eighty-three paroxysmal AF patients underwent PVI using second-generation cryoballoons. The LA was accessed with single 15-Fr steerable sheaths following a radiofrequency transseptal puncture, and the iASD was evaluated with transthoracic echocardiography (TTE), a median of 9...

BACKGROUND: Pulmonary veno-occlusive disease (PVOD) and pulmonary capillary hemangiomatosis (PCH) are rare causes of pulmonary hypertension. Although diagnosis is based on pathological findings, an early diagnosis is crucial because of poor prognosis compared to other types of pulmonary hypertension. Furthermore, vasodilators may cause fatal pulmonary edema in patients with PVOD/PCH. This study aimed to identify specific characteristics for patients with PVOD/PCH to clinically diagnose PVOD/PCH...

50 years ago, Northway described Broncopulmonary Dysplasia (BPD) in preterm infants exposed to mechanical ventilation. Since then, their survival has increased, nevertheless a "new BPD" has appeared and its incidence has not diminished. One of the characteristics of this pathology is the the abnormal vascular remodeling, which in its most severe expression is known as Pulmonary Hyper tension (PH); with an incidence of 17% in patients with BPD, which is proportional to the severity of the disease (33% in severe BPD), and as mortality factor (up to 48% 2-year mortality in PH-BPD)...

A 70-years-old male with a history of hypertension and drug resistant paroxysmal atrial fibrillation (AF) presented to our hospital for catheter ablation to his symptomatic AF. He had no prior surgical or percutaneous procedure to close or exclude the left atrial appendage (LAA). A transesophageal echocardiography (TEE) was performed to rule out intra-cardiac thrombus prior to the ablation procedure. Although the TEE imaging at multiple acquisition angles was obtained, the LAA could not be visualized and an absence of the LAA was suspected...

To identify a predictive value for the exacerbation status of chronic obstructive pulmonary disease (COPD) subjects, we evaluated the relationship between pulmonary vascular measurements on chest CT and severe COPD exacerbation.Six hundred three subjects enrolled in the COPDGene population were included and divided into nonexacerbator (n = 313) and severe exacerbator (n = 290) groups, based on whether they had an emergency room visit and/or hospitalization for COPD exacerbation. We measured the diameter of the main pulmonary artery (MPA) and ascending aorta (AA) at 2 different sites of the MPA (the tubular midportion and bifurcation) on both axial images and multiplanar reconstructions...
