BACKGROUND AND OBJECTIVES Right heart catheterization is traditionally performed using a femoral vein approach that involves admission, bed rest, and risks of bleeding and hematoma. Recent studies have confirmed safety of the use of forearm vein for right cardiac catheterization. In the present study, we evaluated the feasibility of right cardiac catheterization via the antecubital fossa vein i...
background central venous catheterization is done frequently in cardiac surgery and intensive care settings. faulty positioning of the catheter can cause many complications. objectives the aim of our study was to study the average depth of insertion and formulate a general guideline through the right internal jugular vein (ijv). patients and methods the right ijv was cannulated over a period of...
AIMS Real-time MRI creates images with superb tissue contrast that may enable radiation-free catheterization. Simple procedures are the first step towards novel interventional procedures. We aim to perform comprehensive transfemoral diagnostic right heart catheterization in an unselected cohort of patients entirely using MRI guidance. METHODS AND RESULTS We performed X-ray and MRI-guided tran...
Pulmonary artery pressure can be estimated from right ventricular-right atrial pressure gradient in patients with tricuspid regurgitation. The most common approach is to estimate pulmonary artery systolic pressure from right ventricular pressure (assuming no pulmonic stenosis) determined as the sum of the right ventricular-right atrial pressure gradient and either an assumed or clinically deter...
The hepatojugular reflux (HJR) test was studied to assess the ability to clinically predict response during cardiac catheterization and to determine its significance in patients without heart failure and correlate it to their baseline hemodynamic parameters. Sixty-five patients considered to be free of heart failure undergoing routine cardiac catheterization were enrolled. The HJR test, defined...
Methods We included 139 patients undergoing CMR and right heart catheterization within 2 days (n=151 test pairs) for the evaluation of known or suspected pulmonary hypertension. Right ventricular end-systolic volume index (ESVI) and stroke volume index (SVI) were obtained, respectively, from cardiac cine images and phasecontrast of the pulmonary artery after adjusting for body surface area. Rig...
