Objective. To investigate the feasibility of obtaining neo-commissural alignment by withdrawing and readvancing delivery system during transcatheter aortic valve replacement (TAVR) with self-expanding prosthesis. Methods. TAVR was performed in five patients severe stenosis femoral approach. The catheter withdrawn readvanced opposite orientation when Venus-A plus heart (THV) centre marker found to be overlapped or close left at annulus level on fluoroscopic image projection right coronary...
Current recommendations for the best views left main coronary artery (LMCA) ostium intervention are empirical.To determine optimal projection to visualize LMCA using only fluoroscopy.The was determined fluoroscopic images of superimposing lowest points distal ends two J tipped wires in noncoronary cusp (NCC) and right (RCC). This validated independently 3-dimensional computed tomography (3D-CT) reconstruction.Satisfactory overlapping NCC RCC could be obtained 90% (45/50). Between 3D-CT...
Patients experiencing severe aortic stenosis with acute decompensation often face elevated surgical valve replacement risks, leading to high postoperative mortality rates. However, for some patients eligible transcatheter implantation (TAVI), computed tomography angiography assessing the root and coronary artery might be challenging before TAVI procedure. This case highlights a patient who underwent emergency guided by coplane view generated using J-tipped wires fluoroscopy without...
