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...

Doppler echocardiography is commonly used to estimate systolic pulmonary artery pressure and to diagnose pulmonary hypertension, but data relating to its utility in patients with advanced lung disease are limited. In a cohort study of 374 lung transplant candidates, the performance characteristics of echocardiography compared with right heart catheterization in the determination of systolic pul...

This study defines the growth patterns for the external diameters of the pulmonary arteries in human foetuses, including relationships with sex, side of body (right-left) and foetal age. Using anatomical dissection, digital-image analysis (system of Leica Q Win Pro 16) and statistical analysis (ANOVA, regression analysis), a range of external diameters for the right and left pulmonary arteries ...

DOI: 10.5935/abc.20140045 Clinical data: Surgical correction of pulmonary atresia with ventricular septal defect and aortopulmonary collateral arteries was performed in three steps. The first one, with 19 months, with the unification of major collateral artery in the right upper lobe (8 mm) to the right pulmonary artery (RPA), which nurtured the right lower lobe, and Blalock-Taussig anastomosis...

Since the first introduction of pulmonary balloon valvuloplasty by Kan in 1982, the procedure has been used for relief of pulmonary valve stenosis. It is normally recommended that the procedure should be performed for peak-topeak gradients in excess of 50 mm Hg,1 and the balloon/ annulus ratio should be 1.2 to 1.25 for effective and safe results.2 Complications of the procedure are minimal and ...

The hemodynamic evaluation of the pulmonary circulation normally includes the measurements of mean pulmonary artery pressure and a calculation of pulmonary vascular resistance (PVR). The definition of PVR can be improved by the measurements of pulmonary vascular pressures at several levels of flow to derive a pressure-flow line, and the site of PVR can be identified by the analysis of pulmonary...
