Most hospitalized patients with significant tricuspid regurgitation have advanced disease preventing transcatheter tricuspid valve intervention.

Background: More than moderate tricuspid regurgitation (TR) is associated with high mortality. Surgical tricuspid valve repair and replacements are rarely performed due to high operative mortality risk, mainly attributed to late presentation. Novel transcatheter tricuspid valve intervention (TTVI) devices are being developed as an alternative to surgery.

When should fractional flow reserve be performed to assess the significance of borderline coronary artery lesions: Derivation of a simplified scoring system.

Objectives: To derive a simplified scoring system (SSS) that can assist in selecting patients who would benefit from the application of fractional flow reserve (FFR).

Background: Angiographers base decisions to perform FFR on their interpretation of % diameter stenosis (DS), which is subject to variability. Recent studies have shown that the amount of myocardium at jeopardy is an important factor in determining the degree of hemodynamic compromise.

Limitations of embolic protection in saphenous vein graft intervention: insights from 202 consecutive patients.

Between January 2003 and September 2006, a total of 2,541 patients had percutaneous coronary intervention (PCI). Of these, 202 (226 grafts) had at least one saphenous vein graft (SVG) intervention. Adjunctive distal embolic protection (DEP) devices were attempted in 123 SVGs (54.

Percutaneous coronary intervention for myocardial infarction during pregnancy: a new trend?

Recent studies report that American women are increasingly delaying their first births. While the proportion of births in older women has been increasing, there is also increased prevalence of cardiovascular risk factors and complications of pregnancy with increasing maternal age. We present 2 cases of acute myocardial infarction occurring during pregnancy.
