Catheter-induced coronary artery and aortic dissections. A study of mechanisms, risk factors and propagation causes.
Cardiol J
June 2024
Department of Cardiology and Interventional Angiology, Kashubian Center for Heart and Vascular Diseases in Wejherowo, Pomeranian Hospitals, Wejherowo, Poland.
Background: Only the incidence, management, and prognosis of catheter-induced coronary artery and aortic dissections have been systematically studied until now. We sought to evaluate their mechanisms, risk factors, and propagation causes.
Methods: Electronic databases containing 76,104 procedures and complication registries from 2000-2020 were searched and relevant cineangiographic studies adjudicated.
Radiation Reduction and Protection for Radiosensitive Organs (Lens, Thyroid, and Genital Organs) of Patients Receiving Percutaneous Coronary Intervention-Real-World Measurement of Radiation Dose in a Single Center.
J Cardiovasc Dev Dis
August 2021
Cardiovascular Center, Kaohsiung Veterans General Hospital, Kaohsiung 813, Taiwan.
Backgrounds: Reducing radiation exposure is the basic principle for performing percutaneous coronary intervention (PCI). Many studies have confirmed the effect of radiation protection for medical staff, but studies about the effectiveness of protection for patients and real measurement of radiation dose in patients' specific organs are lacking.
Aim: To measure the radiation doses absorbed by patients' radiosensitive organs during PCI and the effectiveness of radiation protection.
Reducing Fluoroscopic and Cineangiographic Contribution to Radiation Exposure for Chronic Total Coronary Occlusion Interventions.
Cardiovasc Revasc Med
March 2022
Medizinische Klinik I, Klinikum Darmstadt GmbH, Darmstadt, Germany.
Background: The treatment of chronic total coronary occlusions (CTO) carries the highest radiation exposure among percutaneous coronary interventions (PCI). In order to minimize radiation damage, we need to understand and optimize the contribution of all components of radiation exposure.
Methods: A total of 1000 CTO procedures performed between 2011 and 2020 were compared according to implemented radiation modifications.
Renal Frame Count and High Blood Pressure.
Clin Ter
May 2020
Bicard Clinic, Cardiovascular Surgery, Bishkek, Kyrgyzstan.
Objective: The aim of the present study was to demonstrate the relationship between hypertension stages according to JNC-8 classification and mean renal frame count (RFC), which is an indicator of renal perfusion.
Methods: In this retrospective study, 100 hypertensive patients without obstructive renal artery disease, who had been evaluated with renal artery angiography for hypertension, were allocated into 2 groups (Stage 1 and Stage 2 hypertension). During coronary angiography, the patients were evaluated by selective renal angiography using 6F Judkins catheter.
Survival after Aortic Valve Replacement for Aortic Regurgitation: Prediction from Preoperative Contractility Measurement.
Cardiology
October 2019
Department of Cardiothoracic Surgery, Weill Medical College of Cornell University, New York, New York, USA.
Background: Noninvasive measurement of myocardial contractility (end-systolic wall stress-adjusted change in left ventricular ejection fraction from rest to exercise [ΔLVEF - ΔESS]) predicts heart failure, subnormal LVEFrest, and sudden death in asymptomatic patients with chronic severe aortic regurgitation (AR). Here we assess the relation of preoperative ΔLVEF - ΔESS to survival after aortic valve replacement (AVR).
Methods: Patients who underwent AVR for chronic, isolated, pure severe AR (n = 66) were followed for 13.
