Letter Case Reports
Acute ST-segment elevation myocardial infarction complicating amoxycillin-induced anaphylaxis: a case report.
A 70-year-old man experienced an amoxycillin-induced anaphylactic reaction complicated by acute inferior myocardial infarction with transient ST-segment elevation. There was a spontaneous resolution of ST-segment elevation and the patient was treated for anaphylaxis. ⋯ Acute ST-elevation myocardial infarction has been described as one of the severe, still rare cardiovascular complications of anaphylaxis. In the present case, according to the previous reports, the main pathogenetic mechanism involved appears to have been coronary vasospasm probably caused by the release of potent vasoactive mast cell derived mediators in the setting of anaphylaxis.

Intra-aortic balloon counterpulsation for complex aortic stenosis in hybrid strategy.
Intra-aortic balloon pumping (IABP) has been considered to be relatively contraindicated in patients with complex aortic stenosis (AS). In this report, we describe the successful implementation of IABP counterpulsation in a patient with severe coronary artery disease and left ventricular dysfunction complicating significant aortic AS. It is shown that adjuvant IABP is a safe and effective method to bridge the unstable hemodynamic condition in the initial percutaneous phase of a hybrid approach. One year after second stage valve surgery, the clinical course remains uneventful.

Review Meta Analysis Comparative Study
The effect of fluvastatin on cardiac outcomes in patients with moderate to severe renal insufficiency: a pooled analysis of double-blind, randomized trials.
Individuals with chronic kidney disease are at high risk for cardiovascular disease and have a high prevalence of hyperlipidemia. Lipid-lowering therapy may help patients with renal disease reduce their risk for cardiovascular events. ⋯ The results of this pooled analysis indicate that fluvastatin is safe and effective for reducing cardiac death and nonfatal myocardial infarction in patients with moderate to severe renal insufficiency. Fluvastatin did not reduce the rate of coronary intervention procedures.

Coronary vasospasm-induced electrical and mechanical complications in patients with acute coronary syndrome and no hemodynamically significant coronary artery disease are rarely reported. ⋯ Coronary vasospasm can be a cause of life-threatening cardiac arrhythmias in patients with acute coronary syndrome and no hemodynamically significant coronary artery disease. Coronary angiography with/without intra-coronary ergonovine testing is necessary in acute coronary syndrome patients to identify the underlying pathology and establish appropriate treatment in these cases.

We studied three patients who had orthodromic atrioventricular reentrant tachycardia (AVRT) using left lateral accessory pathway (AP), with difficulty in identifying the earliest site of retrograde atrial activation. ⋯ In AVRT that has a long VA interval and difficulty in identifying the earliest site of retrograde atrial activation, two different mechanisms existed (mitral isthmus block and conduction through CS musculature). Careful mapping of double atrial potentials and continuous VA activation at the left lateral mitral annulus is essential for determination of a successful ablation site.
