Acetylcysteine for prevention of acute deterioration of renal function following elective coronary angiography and intervention: a randomized controlled trial.

Context: The antioxidant acetylcysteine prevents acute contrast nephrotoxicity in patients with impaired renal function who undergo computed tomography scanning. However, its role in coronary angiography is unclear.

Objective: To determine whether oral acetylcysteine prevents acute deterioration in renal function in patients with moderate renal insufficiency who undergo elective coronary angiography.

Successful rotational atherectomy and stenting in a situs inversus patient.

We describe a case of successful high-speed rotational atherectomy and stenting of a long calcified lesion in a patient with dextrocardia and situs inversus.

Long-term survival of quiescent left atrial myxoma in an elderly patient.

Left atrial myxoma, if left untreated, is inexorably progressive and usually fatal. The classical management of this disease is prompt surgical removal. However, there may be exceptions to this traditional dogma.
