Relationship between coronary diastolic pressure indexes during the wave ‐free period and a novel pressure‐derived index: Diastolic pressure ratio at the optimal point
AbstractObjectivesWe aimed to determine the diastolic pressure ratio at the optimal point (DROP) using a simple measurement algorithm and to compare DROP with distal coronary ‐to‐aortic pressure ratios during the wave‐free period (PRWFP) and at the mid ‐diastolic point (PRMD).MethodsDistal coronary and aortic pressures were measured from color pressure images of 440 beats in 48 patients with coronary stenoses. The DROP measurement point was 67% for one beat between the two rising points on the aortic pressure curve according to the distribution of the wave ‐free period and the mid‐diastolic point.ResultsDROP co...

Is the local guy, just a local guy?
Key Points The most important risk factors and preventive strategies for coronary atherosclerosis are systemic. However, the clinical manifestations of atherosclerotic disease frequently resemble a localized process, instead of a systemic one. In this issue of CCI, Zhang and co ‐workers described the association between the occurrence of stent failure and the changes in the 3D geometry of coronary segments induced by stent implantation. The investigation of local modulators of coronary disease appears as a large and fertile field of future cardiovascular research. (Source: Catheterization and Cardiovascular Interventions)

Delayed aortic dissection and valve thrombosis after transcatheter aortic valve implantation
We report a case of a 78 ‐year‐old female who presented with type A aortic dissection 22 months following transcatheter aortic valve implantation (TAVI). In addition, preoperative echocardiogram showed high gradients across the aortic prosthesis which was found to be thrombosed. At surgery, the intimal tear appeared t o be non‐acute and anatomically related to the rim of the valve cage. The thrombosed valve was not replaced and the patient received anticoagulation therapy following surgery with significant improvement in valve gradients.

Case reports of coronary fibromuscular dysplasia and spontaneous coronary artery dissections
AbstractSpontaneous coronary artery dissection (SCAD) is an important cause of acute coronary syndrome especially in women. The most common underlying predisposing cause of SCAD is fibromuscular dysplasia (FMD), a non ‐inflammatory arteriopathy that results in weakening of the affected arteries, and can cause dissection or aneurysm. Coronary FMD (CFMD) was described as rare, and was shown to cause SCAD in histopathological case reports. Unfortunately, CFMD is challenging to diagnose on coronary angiography, as the findings can be similar to other causes of coronary artery disease. Therefore, we illustrate two case exampl...

Staged revascularization in patients with acute coronary syndromes due to saphenous vein graft failure and chronic total occlusion of the native vessel: A novel concept
We describe a novel concept of “staged re vascularization” in patients presenting with an acute coronary syndrome due to SVG failure, whose native coronary artery supplied by the SVG has a CTO. In the first stage, the culprit SVG lesion is treated restoring flow to the supplied myocardium and minimizing the extent of myocardial injury. Du ring the second stage (typically few weeks later), revascularization of the corresponding native coronary artery lesion(s) is performed, often using the initially treated SVG for retrograde crossing of the native coronary artery CTO. We describe two cases of non‐ST segment e...

Key Points Despite, earlier concerns, is the article by Badri et al., there was no apparent increase in the rate of vascular complications with transfemoral percutaneous coronary intervention (PCI) associated with increasing levels of adoption of transradial PCI by individuals initially identified as primarily femoral operators (> 90% of PCI's via the femoral artery).

Feasibility study of a synchronized diastolic injection with low contrast volume for proper quantitative assessment of aortic regurgitation in porcine models
AbstractObjectivesTo evaluate the in vivo feasibility of aortography with one accurately timed diastolic low ‐volume contrast injection for quantitative assessment of aortic regurgitation (AR) post transcatheter aortic valve replacement (TAVR).BackgroundWith the rise of a minimalistic approach for TAVR, aortography (re)emerges as a pragmatic tool for AR assessment. In a mock circulation system, we have validated the accuracy of a single diastolic injection triggered by electrocardiogram (ECG) with low ‐contrast volume.MethodsTwo ‐phase experiment: first, a series of aortograms were performed in a porcine model, with ...

Recovery of myocardial perfusion after percutaneous coronary intervention of chronic total occlusions is comparable to hemodynamically significant non ‐occlusive lesions
AbstractBackgroundThe benefits of chronic coronary total occlusion (CTO) percutaneous coronary intervention (PCI) are being questioned. The aim of this study was to assess the effects of CTO PCI on absolute myocardial perfusion, as compared with PCI of hemodynamically significant non ‐CTO lesions.MethodsConsecutive patients with a preserved left ventricular ejection fraction ( ≥50%) and a CTO or non‐CTO lesion, in whom [15O]H2O positron emission tomography was performed prior and after successful PCI, were included. Change in quantitative (hyperemic) myocardial blood flow (MBF), coronary flow reserve (CFR) and perfu...
