Authors: Erbel R Abstract The progress in cardiology during the last 50 years can best be studied by looking at the diagnostics and treatment of patients with aortic valve stenosis. Previously, the clinical examination, electrocardiography (ECG) and chest X‑ray were used before heart catheterization, which included a transseptal puncture to complete the indications for surgery in young patients. Nowadays, echocardiography, often combined with a dobutamine stress test, is the primary diagnostic tool to which computed tomography for quantification of valve calcification and cardiac magnetic resonance...

Significant narrowing of the branch pulmonary arteries (PA) may occur following surgical arterioplasty which can lead to disproportionate pulmonary blood flow to the lungs. The conventional procedure of percutaneous transluminal balloon angioplasty of narrowed branch PAs is of limited usefulness in reducing the pressure gradients and importantly, it can have fatal implications like vessel rupture, dissection, aneurysm formation or even death.1 The advent of balloon expandable stents has given better results with lower recurrence rates and complications.

AbstractBackgroundChildren with Fontan circulation are at risk of developing hepatic fibrosis/cirrhosis. Reliable noninvasive monitoring techniques are lacking or under development.ObjectiveTo investigate surrogate indicators of hepatic fibrosis in adolescents with Fontan circulation by evaluating hepatic magnetic resonance (MR) T1 mapping and extracellular volume fraction measurements compared to US shear-wave elastography.Materials and methodsWe analyzed hepatic native T1 times and extracellular volume fractions with modified Look-Locker inversion recovery. Liver stiffness was analyzed with shear-wave elastography. We co...

Abstract BACKGROUND: Pulmonary vascular resistance (PVR) and compliance are comparable in proximal and distal chronic thromboembolic pulmonary hypertension (CTEPH). However, proximal CTEPH is associated with inferior right ventricular (RV) adaptation. Early wave reflection in proximal CTEPH may be responsible for altered RV function. The aims of the study are 1) investigate whether reflected pressure returns sooner in proximal than in distal CTEPH, and 2) elucidate whether timing of reflected pressure is related to RV dimensions, ejection fraction (RVEF), hypertrophy and wall stress. METHODS: Right heart cath...

AbstractPurpose of ReviewCardiac catheterization therapies to treat or palliate infants, children and adults with congenital heart disease have developed rapidly worldwide in both technical innovation and device development in the previous three decades. By reviewing of current status of novel or development of devices and techniques, we will discuss what is likely to happen in paediatric heart intervention in the next decade.Recent FindingsRecently, biodegradable stents and devices, transcatheter pulmonary valve implantation for the native right ventricle outflow tract and MRI-guided interventions have been progressing ra...

CONCLUSIONS: We demonstrate that adult patients in cardiac arrest initiated on VA ECMO in the cardiac catheterization laboratory and cared for by a multidisciplinary shock team in the critical care unit have superior long-term survival and functionally favorable neurologic recovery when compared to current literature.

CONCLUSIONS: In this first-in-patient experience, PZ-128 added to standard antiplatelet therapy appeared to be safe, well tolerated, and potentially reduced periprocedural myonecrosis, thus providing the basis for further clinical trials.

ConclusionPerforming BDG procedure in infants less than 4 months of age is safe, with favorable outcomes. Early BDG is associated with a less ‐smooth postoperative course without a significant increase in early or late mortality.

Conclusions: Somatostatin concentrations were associated with CVP and CI in patients with HF. The pathophysiological mechanism may be related to congestion and/or hypoperfusion of the intestine. Somatostatin was an independent predictor of mortality in advanced HF.Cardiology
