Sometimes, patients scheduled for cardiac operations other than coronary artery bypass may be unsuitable for preoperative coronary angiography. We routinely use intraoperative high-resolution epicardial ultrasound to select the proper target for the graft and to check graft anastomosis integrity. We describe 3 patients who could not undergo preoperative coronary angiography for different reasons.

Article Synopsis
- - The study compared the effects of Transcatheter Aortic Valve Implantation (TAVI) and traditional aortic valve replacement (AVR) on left ventricular (LV) function and geometry in patients with aortic stenosis, assessing 45 TAVI and 33 AVR patients through echocardiograms before and two months after procedures.
- - Results showed that TAVI patients were older and had greater LV mass index (LVMi) at baseline; however, both procedures significantly reduced transvalvular gradients and LV metrics after two months, with TAVI showing a more pronounced improvement in LV geometry and function.
- - The findings indicate that TAVI leads to a greater reduction in estimated LV filling pressure compared to AVR, and these
Coexisting arterial diseases and endoprosthesis to peripheral-vessel mismatch may impair conventional femoral access for endovascular treatment of descending aorta aneurysms. Furthermore, previous abdominal operations can make an optional aortic-iliac approach more difficult. We introduced a new minimally invasive access through the aortic arch, which completely avoids the aortic-iliac access and minimizes surgical trauma.

Although these strategies have clear advantages in terms of reduced surgical trauma, no further refinements in terms of cosmetic results have been made for women.
Methods: Aortic valve replacement was performed in 4 women via a right anterior submammary minithoracotomy without rib resection.
Coronary ostial stenosis is a life-threatening complication of aortic valve replacement. We describe the case of a patient who developed symptoms and signs related to coronary insufficiency 4 months after aortic valve replacement. In view of a coronary angiogram revealing a 99% left main stem stenosis, an urgent revascularization procedure was performed.
