Coronary blood flow and perfusion pressure during coronary angiography in patients with ongoing mechanical chest compression: A report on 6 cases
Abstract: Patients with pulseless electrical activity or refractory ventricular fibrillation have a very bad prognosis. Coronary angiography and angioplasty may be required to restore an effective circulation, but this must be performed whilst chest compressions are continued. The LUCAS chest compression device is suitable for this purpose. So far there are no reports on the effect of this device on coronary circulation in humans. We monitored the coronary perfusion pressure assessed invasively as the difference between the diastolic pressures at the coronary ostium and right atrium, and compared these pressures with coronary flow graded using the TIMI scale in 6 patients. In 4 out of 6 we found a satisfactory coronary artery perfusion pressure and TIMI grade 3 flow (normal) on coronary an......

Management of bleeding from pseudoaneurysms following pancreaticoduodenectomy.
CONCLUSION: Bleeding pseudoaneurysms are among the most serious and fatal complications following pancreaticoduodenectomy. Diagnostic angiography has been preferred over endoscopy and is rapidly becoming the standard therapeutic treatment for bleeding pseudoaneurysms.

Study Questions Frequency Of Heart Angiograms
A recent study raises questions about the frequency of doctors' use of elective heart angiograms, which showed no disease in almost 40 percent of patients. BusinessWeek reports: "Doctors may be sending patients too quickly for elective angiograms to detect heart disease, exposing them to radiation and driving up U.S. health-care costs, a study suggests. An analysis of records of about 400,000 patients concluded that 37... (Source: Health News from Medical News Today)...

[Transient subclavian artery spasm observed during percutaneous coronary intervention for acute myocardial infarction.]
Authors: Karakurt O, Kılıç H, Akdemir R
A 68-year-old man with a history of two coronary artery bypass operations was admitted with acute inferior myocardial infarction (AMI) and cardiogenic shock. The electrocardiogram showed ST-segment elevation in leads D2, D3, and aVF. Coronary angiography demonstrated a 75% thrombotic stenosis in the right coronary artery (RCA), 90-99% stenosis in the intermediate coronary artery, and plaques in the circumflex artery. While assessing the patency of bypass grafts, a 99% stenosis was noted in the distal subclavian artery. The culprit artery was deemed to be the RCA, and after direct stenting, TIMI III flow was achieved. Ten days later, stent implantation was performed for the intermediate coronary artery, at which time distal subcla......

Split right coronary artery: a report of two cases.
We present two cases (59-year-old male, 50-year-old female) who sought treatment for exercise-induced angina pectoris. Coronary angiography revealed a split RCA in both cases. In the first case, the RCA consisted of two well-developed arteries bifurcating immediately after its origin from the sinus of Valsalva. In the second case, the RCA split from adjacent ostia into two major arteries almost identical in size. In both cases, the split RCAs had a parallel course. Both patients were scheduled to receive medical treatment and had an uneventful follow-up of 15 and 11 months, respectively.

Outcome of coronary plaque burden: a 10-year follow-up of aggressive medical management
Background:
: The effect of aggressive medical therapy on quantitative coronary plaque burden is not generally known, especially in ethnic Chinese. AIMS: We reasoned that Cardiac CT could conveniently quantify early coronary atherosclerosis in our patient population, and hypothesized that serial observation could differentiate the efficacy of aggressive medical therapy regarding progression and regression of the atherosclerotic process, as well as evaluating the additional impact of life-style modification and the relative effects of the application of statin therapy.MethodS: We employed a standardized Cardiac CT protocol to serially scan 113 westernized Hong Kong Chinese individuals (64 men and 49 women) with chest pain and positive coronary risk factors. In all cases included for this se......

High-resolution ex vivo magnetic resonance angiography: a feasibility study on biological and medical tissues
Conclusions:
Ex vivo MRA provides high-resolution of fresh tissue and delineates fine structures that we were not able to visualise using CT. We found that the use of our clinical imaging systems provided MRA which took advantage over CT angiography in its ability to visualize vessel configuration while avoiding interfering signals from adjacent bones. Interestingly, we found that vascular tissue becomes leaky when formalin-fixed, leading to increased permeability and extracellular leakage of MR contrast agent.

Noninvasive Detection of Vulnerable Plaques: Are We There Yet?
This study is provocative indeed, considering that, up to now, the diagnosis of vulnerable plaque (VP) (defined as those at higher risk for future rupture/thrombosis) has been elusive (). In fact, despite the use of sophisticated and highly accurate intracoronary diagnostic techniques (intravascular ultrasound, virtual histology, elastography, thermography, coronary angioscopy, and optical coherence tomography) the identification of VP has been not only a moving target but also clinically unreliable (). Currently, with invasive techniques, unique insights on plaque characteristics including morphology, composition, physiologic properties, and even measurements of local temperature, macrophage content and fibrous cap thickness can be obtained; yet we cannot accurately predict their prognosi......

Reply
We thank Dr. Alfonso for interest in our manuscript and very insightful comments. We agree that feasibility of noninvasive identification of plaques vulnerable to rupture might have significant clinical implications, and clarify here the methodological issues raised. As described in our paper (), acute coronary syndromes (ACS) included acute myocardial infarction with the elevation of troponin level and unstable angina without troponin elevation. Our report characterized the plaques that resulted in ACS and excluded the lesions already subjected to intervention or those selected for intervention. As noted in the report, 3 patients developed ACS involving the previously treated lesion and were excluded from the analysis. Also, target lesion could not be identified in 8 patients with ACS, be......
