Diagnosis and prognostication in patients with complex cardiopulmonary disease can be a clinical challenge. A new procedure, MRI catheterization, involves invasive right-sided heart catheterization performed inside the MRI scanner using MRI instead of traditional radiographic fluoroscopic guidance. MRI catheterization combines simultaneous invasive hemodynamic and MRI functional assessment in a...

Radionuclide ventriculography of the right heart was performed in 56 patients within two weeks of cardiac catheterization using a gated first-pass technique. Thirteen patient served as normal controls, and 43 patients had severe aortic or mitral valve disease or both, 35 of whom subsequently underwent valve surgery. Right ventricular ejection fraction (RVEF) and the presence of central venous r...

OBJECTIVE To assess the accuracy of echocardiography for predicting pulmonary arterial hypertension (PAH) in a cohort of patients with systemic sclerosis and other connective tissue diseases, and to evaluate whether addition of the right ventricular (RV) Tei-index contributes to the non-invasive diagnosis of PAH in this patient group. PATIENTS AND METHODS Ninety-eight patients with systemic s...

Pulmonary hypertension (PH), second only to left heart diseases (LHD), is a frequent problem in clinical practice. At the same time, left heart diseases represent the most common cause of pulmonary hypertension, and the occurrence of PH in patients with chronic heart failure is usually associated with worse functional class, and prognosis. Right heart catheterization (RHC) is the "gold standard...

A new R package for matching in observational studies, rcbalance, is presented. rcbalance is designed to exploit sparsity among potential treated-control pairings and can conduct matches on a very large scale at low computational cost. Unlike existing packages, it also supports refined covariate balance constraints, which use prioritized lists of nominal covariates to induce high degrees of bal...

Introduction: Arteriovenous malformations (AVMs) are uncommon vascular lesions that can arise in any part of the body. Case Report: In this case study, we presented a huge AVM of the upper lip in a 70-year-old man that he noticed since 5years ago with slow growth in this period. Computed tomography angiography revealed a large AVM with feeders from the right...

n the first case of percutaneous coronary intervention (PCI), reported by Dr Gruntzig in 1978, the transfemoral approach was used. Since then, many interventional cardiologists have performed PCI using that approach. However, in the history of cardiac catheterization, the first case was performed by a urologist Dr Forssmann, from his own brachial vein to the right side of his heart in 1929, for...

Background: Pulmonary hypertension is a condition which there an increase in mean pulmonary artery pressure measured at ≥25 mmHg. The gold standard diagnosing this right heart catheterization. Enlargement of descending on chest radiographs sign hypertension. However, the value radiographic measurements reported was diverse. study analyzes correlation between (RDPA) diameter and means catheter...
