Evaluation of coronary flow with computed tomography derived FFR: Advantages and pitfalls
No full textCoronary computed tomographic angiography (CCTA) is an excellent noninvasive, anatomic imaging modality for direct visualization of coronary arteries and for the assessment of coronary artery disease (CAD). CCTA has high sensitivity and high negative-predictive value for the identification of obstructive CAD; however, its specificity and positive-predictive value are low. After more than a decade of using CCTA to assess the anatomic severity of CAD, novel modalities of obtaining functional information from CCTA have been developed to increase its specificity and accuracy. These modalities use computational fluid dynamics to calculate fractional flow reserve (FFR) from CCTA datasets. Computed tomography-derived FFR (FFRCT) predicts virtual hyperemia for computation. Therefore, no additional image acquisition, medication, radiation exposure, or pharmacologic stress agent during CCTA examination are necessary for the calculation of FFRCT. Multiple, prospective single or multicenter studies have shown that FFRCT is poised to become a gate-keeper for catheterization laboratory. In this article, we aim to review the principles, diagnostic accuracy, advantages, limitations, and pitfalls of FFRCT

Wellens' Syndrome: Critical Left Anterior Descending Artery Stenosis
No full textWellens sendromu (WS) sol ön inen arterin kritik daralması ile ilişkili elektrokardiyografik (EKG) T dalga değişiklikleri paternidir. EKG değişiklikleri V2-4 prekordiyal derivasyonlarda derin, simetrik veya bifazik T dalgaları olarak tariflenir. Bu sendromda T dalga değişiklikleri genellikle ağrısız dönemde oluşur. Bu değişikliklerin sebebi tam bilinmemektedir. Bu gözlenen T dalga değişiklikleri infarktüs öncesi bulgu olup anterior miyokard infarktüsüne ilerleyebilir. Bu sendrom ile başvuran olgulara provakatif test yapılmaksızın direk koroner anjiyografi planlanmalıdır. Erken koroner revaskülarizasyon yapılmadığı zaman mortalite ve morbidite sebebi olabilir. WS'ye günlük klinik pratikte sık rastlanmasına rağmen kardiyoloji kitaplarında nadiren tariflenmiştir. Amacımız WS'nin klinik önemine dikkati çekmektir. WS ile acil servise başvuran 44 yaşında bir erkek hastayı sunuyoruz.Wellens' syndrome (WS) is a pattern of electrocardiographic (ECG) T-wave changes associated with critical narrowing of the left anterior descending artery. ECG changes are described as deeply-inverted or symmetrical or biphasic T waves in V2-V4. T wave changes in the syndrome usually occur during a pain-free interval. The origin of these changes is unclear. These T wave changes are the sign of preinfarctional state and can progress to myocardial infarction. Coronary angiography should be planned for patients presenting with this syndrome without performing provocative tests. There is an increased risk for morbidity and mortality in the absence of urgent coronary revascularization. Although WS is frequently encountered in the daily clinical practice, it is rarely described in cardiology books. Our aim was to point out the clinical importance of WS. We report the case of a 44-year-old male patient who presented to the emergency department with WS
