Anaphylactic Shock Due to Technetium (99mTc)-Tetrofosmin During Myocardial Perfusion Scintigraphy: A Case Report.

Myocardial perfusion scintigraphy is a popular minimally invasive method for evaluating chronic coronary disease (CCD). We performed myocardial scintigraphy to assess CCD in a 74-year-old man with a history of allergy to contrast media. The patient developed anaphylactic shock immediately after the administration of the technetium (Tc)-tetrofosmin preparation.

A rare case of stiff left atrial syndrome caused by both coconut left atrium and vertebral compression: a case report.

Background: Calcification of the left atrium (LA) is a rare condition and can be the result of long-standing rheumatic mitral stenosis or an unusual complication after mitral valve replacement. Cases of massive LA calcification have sometimes been referred to as those with 'coconut LA' or 'porcelain LA'.

Case Summary: A 75-year-old woman was referred to our hospital because of chest discomfort and exertional dyspnoea.

Change of the complexity of coronary artery disease after percutaneous coronary intervention with drug-eluting stent.

We investigated changes of the complexity of coronary artery disease (CAD) after drug-eluting stent (DES) implantation using SYNTAX score and the predictor of worsened SYNTAX score at follow-up. 116 consecutive patients who underwent de novo PCI with first-generation DES were enrolled. SYNTAX scores were obtained from coronary angiography before PCI, just after final PCI and at follow-up after 6-8 months and investigated.

An assessment of risk factors for the complexity of coronary artery disease using the SYNTAX score.

In 2005, the SYNTAX score was reported as "an angiographic tool grading the complexity of coronary artery disease". We investigated risk factors for the complexity of coronary artery disease (CAD) using SYNTAX scores in patients with new-onset CAD. The subjects were 359 consecutive cases that underwent de novo percutaneous coronary intervention (PCI) or coronary artery bypass graft surgery without previous PCI history.
