We present a 40 year old asymptomatic man with mild left main artery narrowing who demonstrated extreme discordance between symptom presentation and ischemic burden i.e. visual (angiographic) and ischemic (functional) mismatch. The use of an appropriately selected screening stress test can lead to an appropriate decision for revascularization, supported by landmark risk assessment documents and revascularization trials.

Transcatheter aortic valve replacement (TAVR) has become the preferred therapy for treatment of severe aortic stenosis in patients at intermediate to high risk of perioperative mortality following surgical aortic valve replacement. Haemodynamic assessment is an integral part of the procedure, and it is crucial for the operator to have an in-depth understanding of the haemodynamic alterations that occur during balloon aortic valvuloplasty and transcatheter valve deployment. Comprehension of the haemodynamic tracings is also pivotal for early recognition of periprocedural complications...

DM patients with stenoses whose FFR > 0.80 have a relatively high 14% rate of deferred lesion failure (i.e., revascularization or MI). IDDM and prior revascularization were independent predictors of deferred lesion failure FFR predicts outcomes, but is a less effective predictor in diabetics due to diffuse atherosclerosis microvascular disease.

Although the use of drug-eluting stents (DES) has dramatically decreased the incidence of in-stent restenosis (ISR), concerns regarding the late manifestations of ISR remain. Optical coherence tomography (OCT) imaging provides unique insights into characteristics and patterns of ISR. We report a case of late DES ISR with unusual heterogeneous intracoronary luminal characteristics suggestive of vulnerable atherosclerotic plaque activity by OCT imaging. This case demonstrates that late ISR after DES may involve more than mere neointimal hyperplasia with lesion-associated craters, septae, and neoatherosclerosis...

This retrospective study compares the performance of transradial diagnostic procedures using the single versus Judkins catheter approach. The Judkins approach had a 15% lower patient radiation exposure than single catheter approach while fluoroscopy time was comparable. Future studies of comparing such techniques may always be limited by operator preference, experience, and comfort.

The application of computational fluid dynamics to coronary computed tomography angiography allows Fractional Flow Reserve (FFR) to be calculated non-invasively (FFRCT), enabling computation of FFR from coronary computed tomography angiography acquired at rest both for individual lesions as well as along the entire course of a coronary artery. FFRCT, validated in a number of accuracy studies and a large clinical utility trial, is beginning to penetrate clinical practice. Importantly, while accuracy trials compared FFRCT to invasively measured FFR at a single point in the coronary tree, clinical reports of FFRCT provide information regarding a patient's entire coronary vasculature...

REVIEW
Michael Eskander, Morton J Kern
Heart failure is a clinical diagnosis that is supported by various laboratory, imaging, and invasive hemodynamic measures. There is no single diagnostic test. A variety of structural and/or functional myocardial abnormalities can lead to the inability of the heart to fill or eject blood. Despite ejection fraction being the most commonly assessed measure of systolic function in clinical practice, it is a poor measure of contractility because it is susceptible to loading conditions and chamber size. Invasive hemodynamic assessment remains of great importance in the evaluation of patients with myocardial disease or hypertrophic cardiomyopathy...

Arnold H Seto, Morton J Kern
Various definitions of post-PCI MI have been recommended by different professional societies and studies. This present study suggests that the troponin-based 3rd universal definition of post-PCI MI has prognostic value for recurrent MI but not mortality alone, unlike the CK-MB based SCAI definition. Absent a consensus on the best definition, clinical trials should report outcomes based on multiple definitions of post-PCI MI.
