The dilatation of pulmonary artery is a rare condition and called as pulmonary artery aneurysm. Aneurysm of both the pulmonary trunk and the ascending aorta is even rarer. Symptoms are due to aneurysm compression in adjacent anatomical structures. The main indicator of treatment is the pulmonary artery pressure. The prognosis and treatment of pulmonary artery aneurysm is unclear. Herein we pres...

conclusions cp could be considered as an index for the prediction of vasoreactivity in patients with ipah. prediction of long-term response to calcium channel blockers in patients with ipah and a positive vasoreactive test by this index should be addressed in further studies. patients and methods fourteen patients with ipah and a vasoreactive adenosine vasoreactivity testing according to the es...

BACKGROUND Echocardiographic studies have contributed to progress in the understanding of the pathophysiology of the pulmonary circulation and have been shown to be useful for screening for and prognostication of pulmonary hypertension, but are considered unreliable for the diagnosis of pulmonary hypertension. We explored this apparent paradox with rigorous Bland and Altman analysis of the accu...

Intravascular lithotripsy (IVL) is a novel method based on pulsatile ultrasonic pressure waves specifically aimed to modify circumferential and transmural calcium plaques. We report the successful application of shockwave IVL catheter® in child with chronic thromboembolic pulmonary hypertension due calcified thrombi both lower lobes. Compared conventional high-pressure balloon angioplasty, sign...

BACKGROUND Serotonin promotes pulmonary arterial vasoconstriction and pulmonary arterial smooth muscle cell proliferation, thereby having the potential to increase pulmonary arterial blood pressure. Although serotonin reuptake inhibitors (SRIs) might inhibit further deterioration in patients with manifest pulmonary arterial hypertension, they may induce pulmonary hypertension in healthy newborn...

The pulmonary artery dissection (PAD) is a rare and life-threatening event, usually secondary to a chronic pulmonary artery hypertension. We report the case of pulmonary artery dissection undergoing medical treatment by conservative management, discovered by performing a computed tomography (CT), and describe the clinical and therapeutic characteristics with the literature review.

BACKGROUND Metabolic disease can lead to intrinsic pulmonary hypertension in experimental models. The contributions of metabolic syndrome (MetS) and obesity to pulmonary hypertension and right ventricular dysfunction in humans remain unclear. We investigated the association of MetS and obesity with right ventricular structure and function in patients without cardiovascular disease. METHODS AN...

Pulmonary hypertension is a common complication of sickle cell anemia. Despite the fact that the elevations in pulmonary artery pressures are slight, morbidity and mortality are high. In adult sickle cell anemia patients, pulmonary hypertension is emerging as a major risk factor for death. The pathogenesis of sickle cell anemia-related pulmonary hypertension is multifactorial, including hemolys...
