significant improvement in severely stunned left ventricle after percutaneous coronary intervention

Rescue percutaneous coronary intervention revealing impending left ventricle rupture.

to lack of improvement, she was transferred for rescue percutaneous coronary intervention. Successful percutaneous coronary intervention was performed on the left anterior descending artery, although persisting slow flow was noted (Figs. 1B and 1C, Online Video 1). Diffuse narrowing of the distal left anterior descending artery was also observed, suggesting external compression of the vessel. T...

Left main percutaneous coronary intervention.

The introduction of drug-eluting stents and advances in catheter techniques have led to increasing acceptance of percutaneous coronary intervention (PCI) as a viable alternative to coronary artery bypass graft (CABG) for unprotected left main disease. Current guidelines state that it is reasonable to consider unprotected left main PCI in patients with low to intermediate anatomic complexity who...

Percutaneous coronary intervention in unprotected left main coronary artery disease.

Percutaneous coronary intervention for unprotected left main coronary artery disease is potentially an important intervention in surgically unstable patients. A detailed review of medical record and visual analysis of coronary angiography and PCI procedure was undertaken. The study was conducted at the Aga Khan University Hospital, from January 2003 to December 2007. Patients included in the st...

Improvement in coronary haemodynamics after percutaneous coronary intervention: assessment using instantaneous wave-free ratio

OBJECTIVE To determine whether the instantaneous wave-free ratio (iFR) can detect improvement in stenosis significance after percutaneous coronary intervention (PCI) and compare this with fractional flow reserve (FFR) and whole cycle Pd/Pa. DESIGN A prospective observational study was undertaken in elective patients scheduled for PCI with FFR ≤ 0.80. Intracoronary pressures were measured at r...

Complete improvement in a patient with multiple irreversible defects of the left ventricle on 99m technetium-sestamibi SPECT after percutaneous coronary intervention.

99mTc-sestamibi has been investigated as a potential viability marker; initial studies have shown good concordance between 201Tl and 99mTc-sestamibi activities in both viable and nonviable myocardium. However, assessment of myocardial viability by 99mTc-sestamibi remains controversial for tissue recovery after revascularization. Here, we present a patient with several regions of severely dimini...
