| Introduction |
|---|
Four months before the second opinion, the patient had undergone a
second thallium stress test for follow-up. The study was suggestive of
mild inferoposterior ischemia, and the patient again underwent
diagnostic coronary angiography. The arteriogram
was reported to be notable for hemodynamically
significant lesions in the proximal left anterior descending
coronary artery (LAD)
(Figure
, A), in the
circumflex coronary artery (LCx) (B), and in the origin of a
posterolateral branch of the right coronary artery (C). At the
time of the diagnostic coronary angiography,
balloon angioplasty was performed on the LAD stenosis (D).
Approximately 1 week later, angioplasty was performed on the LCx and
posterolateral coronary arteries, with a stent being placed in
the LCx.

Two months after the second procedure, the patient became
symptomatic for the first time and was hospitalized because
of substernal chest pain occurring with minimal exertion. After
stabilization with intravenous heparin, aspirin, and
nitrates, a coronary angiogram was obtained that demonstrated a
high-grade stenosis
