By Charles White, Joseph Chen

This easy-to-use, clinically orientated studying advisor offers one hundred fifteen distinct circumstances that conceal the scope of cardiac imaging, together with congenital, ischemic, myocardial, valvular, and pericardial middle sickness, in addition to postintervention problems. Given the normal structure of challenge and answer, each one case is dependent for powerful evaluation and studying for either the resident-in-training and the skilled clinician. instances are classified by way of part: the 1st features a short assessment of uncomplicated anatomy, and next sections are divided through affliction type. that includes over 440 pictures and observed by way of short but informative discussions, Cardiac Imaging Cases is the perfect source and reference consultant for an individual within the box of cardiovascular radiology. additionally to be had as an app for iPad at the Apple iTunes shop.

100 Questions in Cardiology

(BMJ Books) UCL Hospitals, London, united kingdom. greater than a hundred questions are responded via major cardiologists. sensible advisor to administration of complex events. For practitioners and citizens. Softcover.

Cardiovascular Biomaterials

Cardiovascular Biomaterials offers present examine mate- rial built by means of individuals from universities und profes- sional laboratories within the UK,USA, Canada, and Germany, every one recognized for his or her talents during this box. The publication starts off with an advent to the paintings of constructing a brand new synthetic artery, and proceeds during the themes of the issues and advancements in center valve replacements, vehicle- diac support units, mechanical homes of arteries and arterial grafts, biostability of vascular prostheses, blood compatibility in cardiopulmonary pass, collagenin aerobic- vascular tissues and the pacemaker approach.

Blood Pressure Monitoring in Cardiovascular Medicine and Therapeutics

During this newly up-to-date moment version of Blood strain tracking in Cardiovascular medication and Therapeutics, William B. White, MD, and a panel of hugely amazing clinicians supply a serious overview of each point of the review of hypertension. This comprises domestic and ambulatory blood strain tracking, the connection among whole-day blood strain and the heart problems method, and the consequences of antihypertensive remedies on those blood strain parameters.

Lauderdale, Florida) Figure 11-2 Image courtesy of Jacob Kirsch, MD (Cleveland Clinics, Ft. Lauderdale, Florida) 25 Case 11 Bland-White-Garland Syndrome Findings ▶ An anomalous coronary artery, usually the LM segment of the LCA (arrow), arises from the PA (asterisk) and courses normally in the anterior interventricular groove Differential Diagnosis ▶ Other coronary artery anomalies ▶ Coronary artery fistula Teaching Points ▶ Also known as anomalous left coronary artery from the pulmonary artery (ALCAPA) ▶ Other coronary artery anomalies do not arise from the PA ▶ In coronary artery fistula, the LCA arises from the coronary ostium correctly, although abnormal branch vessels of the fistula may connect to the PA ▶ Most patients usually present as infants with heart failure; in rare cases, adults may present with angina, myocardial infarction, or heart failure ▶ Lower PA pressure results in the coronary steal phenomenon, which in turn results in ischemia Management ▶ In infants, reimplantation or intrapulmonary conduit of the anomalous coronary artery to the aorta can be performed ▶ In adults, the anomalous LCA can be ligated and CABG can be performed Further Readings Cowles RA et al.

Radiographics. 2006;26(2):317–333. 22 Case 10 History ▶ None 23 Case 10 Myocardial Bridging Findings ▶ A band of myocardial muscle (arrows) overlying a segment of coronary artery ▶ A segment of the coronary artery courses intramyocardially and resurfaces to the epicardial fat ▶ Most common in the middle segment of the LAD artery (as in this case), followed by LCx and RCA ▶ Electrocardiography (ECG)-gated reconstruction can be performed during the systolic and diastolic phases to assess maximal luminal narrowing and dilation, respectively Differential Diagnosis ▶ Coronary artery disease ▶ Cardiac tumor ▶ Hypertrophic cardiomyopathy Teaching Points ▶ Segment of the coronary artery proximal to the myocardial bridge is predisposed to atherosclerotic changes, while the tunneled area is relatively protected ▶ Cardiac tumor may invade epicardial fat and engulf the coronary arteries ▶ Hypertrophic cardiomyopathy may mimic myocardial bridging due to asymmetrical enlargement of the myocardium partially engulfing the coronary artery ▶ Presentation: Most cases are asymptomatic; symptoms include angina, myocardial infarction, life-threatening arrhythmias, and even sudden death ■ Due to marked systolic compression of an epicardial coronary arterial segment by the overlying myocardium Management ▶ None; usually asymptomatic ▶ Medical (ß-blocker or calcium channel blocker) or surgical (coronary revascularization or septal myomectomy) treatment in symptomatic patients Further Reading Konen E et al.
