We examined the characteristics and outcomes of 1598 CTO-PCIs. Despite more complex clinical and angiographic characteristics, we found that elective use of mechanical circulatory support (MCS) in high-risk patients was associated with similar techni…
A group of 2899 patients with acute coronary syndromes was studied to compare the safety and efficacy of those with LMCA disease vs those without LMCA disease. The primary endpoints of independently adjudicated major adverse cardiovascular and cerebr…
We investigated 477 patients who underwent TAVR and divided subjects into two groups according to malignancy status. We found that mere history of malignancy among elderly patients does not adversely affect outcomes after TAVR; however, history of re…
Axillary artery cannulation is an important alternate access site for catheter-based procedures in selected patients. Our objective was to identify a fluoroscopic bony landmark for safe percutaneous axillary artery cannulation.
End-stage renal disease (ESRD) is a relative contraindication for forearm cardiac catheterization, yet this approach is used in everyday practice. We compared femoral and forearm approach for cardiac catheterization in ESRD patients. 
Operator quality assessment in PCI is disposed to the view that the more cases the interventionist performs, the more proficient the operator. However, the evidence does not support any particular volume level as a quality indicator.
Transient elevation of LV diastolic pressure above LA pressure can occur in severe aortic regurgitation in the diastasis phase. Mitral E wave reversal in such a situation could serve as non-invasive evidence of elevated left ventricular diastolic pre…
A 47-year-old patient with severe tricuspid and pulmonary regurgitation was electively admitted for surgical replacement of both valves. Post-op ECG changes suggested acute myocardial ischemia. Angiography revealed kinking in the distal RCA causing s…
A 45-year-old man presented after an episode of central chest pain. Catheter angiography revealed an aberrant CX artery and high-grade stenosis in the mid RCA and proximal CX arteries. Previous case series have suggested that the retroaortic portion…
To our knowledge, this is the first documented case of successful TAVI for severe quadricuspid aortic valve (QAV) stenosis performed in the U.S. and the first documented Sapien 3 valve implantation in a severely stenotic QAV.
