Acute occlusion of the left internal mammary artery (LIMA) graft late after coronary artery bypass grafting surgery is a rare and potentially life-threatening complication. We describe a case of acute myocardial infarction 19 years after coronary artery bypass graft surgery due to acute occlusion of the distal anastomosis of a LIMA graft to the lef...
Chronic total occlusion (CTO) remains a technical challenge for the interventional cardiologists. The application of the retrograde approach has dramatically improved success rates of CTO PCI. However, retrograde wire externalization could be very difficult especially when the antegrade guiding catheter cannot sit into the coronary ostium stably. W...
Residual patent ductus arteriosus (rPDAs) can occur following surgical or transcatheter treatment, and are indicated for closure because of the risks of infective endarteritis and hemolysis in addition to the hemodynamic effect of the residual left-to-right shunt. This retrospective descriptive study describes our experience at two Egyptian centers...
A 73-year-old man with severe, symptomatic secondary mitral regurgitation (MR) underwent successful transcatheter mitral valve replacement using the Tendyne™ mitral valve system. The device was deployed from the left ventricular (LV) apex and secured in position by a tether attached to an epicardial pad. Three days postoperatively, the patient deve...
To study radiation exposure to the primary operator during diagnostic cardiac catheterizations using a radio-dense RAD BOARD® radial access arm board. The use of radial access for catheterization in the United States has increased from 1% in 2007 to 41% in 2018. Compared to femoral access, operator radiation exposure from radial access is similar o...
This study aimed to compare the clinical impact of mild postprocedural aortic regurgitation (post-AR) to that of none-trivial post-AR after transcatheter aortic valve implantation (TAVI) and to identify the vulnerability factors to mild post-AR. Moderate-severe post-AR, associated with increased mortality, is an important issue. However, the clinic...
To evaluate the long-term impact of coronary artery disease (CAD) and heart team-guided incomplete coronary revascularization in patients undergoing transcatheter aortic valve implantation (TAVI). Revascularization strategy of CAD diagnosed with routine coronary angiography before TAVI is uncertain. Five hundred and forty consecutive TAVI patients ...
Investigation of novel vertical radiation shield (VRS) in reducing operator radiation exposure. Radiation exposure to the operator remains an occupational health hazard in the cardiac catheterization laboratory (CCL). A mannequin simulating an operator was placed near a computational phantom, simulating a patient. Measurement of dose equivalent and...
Patients with acute coronary syndrome (ACS) might represent a specific subgroup, in which bioresorbable scaffold implantation in percutaneous coronary intervention (PCI), might lead to better outcomes when compared to conventional treatment with metallic drug eluting stents. In this prespecified subgroup analysis of the Amsterdam Investigator-Initi...
To assess closed-loop communications (readback), a fundamental aspect of effective communication, among cardiovascular teams and assess improvement efforts. Effective communication within teams is essential to assure safety and optimal outcomes. Readback of verbal physician orders is a hospital and national requirement. Single-center observational ...
