Left Heart Catheterization [PDF]

Circulation Research, 1954
Direct puncture of the left atrium with a needle, through which a catheter can be passed, allows pressure measurements in atrium, left ventricle and aorta. This procedure is considered to be more helpful than right heart catheterization in evaluation of patients with mitral and aortic valvular lesions.

Right heart catheterization for pulmonary hypertension during the coronavirus disease 2019 pandemic

Pulmonary Circulation, 2020
Right heart catheterization is an essential diagnostic modality in the evaluation of pulmonary hypertension. The coronavirus disease 2019 pandemic has resulted in deferral of elective procedures including right heart catheterization.

Prognostic value of optical flow ratio for cardiovascular outcomes in patients after percutaneous coronary stent implantation

Frontiers in Cardiovascular Medicine, 2023
BackgroundThe relationship between the optical flow ratio (OFR) and clinical outcomes in patients with coronary artery disease (CAD) after percutaneous coronary stent implantation (PCI) remains unknown.ObjectiveTo examine the correlation between post-PCI

Pulmonary Vascular Remodeling and Prognosis in Patients Evaluated for Heart Transplantation: Insights from the OCTOPUS-CHF Study

Journal of Cardiovascular Development and Disease, 2022
Objective: In patients with advanced heart failure, the intravascular optical coherence tomography (OCT) of subsegmental pulmonary artery measurements is correlated with right heart catheterization parameters. Our aim was to study the prognostic value of

Prognostic value of texture analysis from cardiac magnetic resonance imaging in patients with Takotsubo syndrome: a machine learning based proof-of-principle approach

Scientific Reports, 2020
Cardiac magnetic resonance (CMR) imaging has become an important technique for non-invasive diagnosis of takotsubo syndrome (TTS). The long-term prognostic value of CMR imaging in TTS has not been fully elucidated yet.

Hemodynamic Consequence of Interventional Cardiac Catheterization in the Early Postoperative Period after Congenital Heart Surgery

Hearts, 2023
While still considered a high-risk procedure, cardiac catheterization during the early postoperative period is being performed more frequently in the current era. Limited data are currently available concerning the acute hemodynamic consequences of these
