Intracardiac echocardiography has been used in percutaneous tricuspid annuloplasty and is now shown also to work in transcatheter , operators reported in a case study. This mode of imaging can be useful when a transesophageal echo doesn't provide a good view due to acoustic shadowing from intracardiac prostheses, lipotamous septa, or anatomic abnormalities.

Regadenoson is a to adenosine in measuring fractional flow reserve and can be reversed by aminophylline, researchers showed in Clinical Cardiology.

It may save time and money to undergo an for lower-extremity peripheral artery disease rather than bypass surgery, one group suggested in the American Journal of Cardiology. To top it off, endovascular management was associated with lower in-hospital morbidity and mortality.

Within a year of , one in ten U.S. patients were subsequently hospitalized for a major adverse limb event. From 2009 to 2014, the country saw fewer limb-related and cardiovascular hospitalizations -- while the rate of outpatient endovascular revascularization increased.

Patients can get away with no greater than 0.5 mm after stenting, according to a meta-analysis in European Heart Journal. Any more than that, and the risk of target lesion revascularization is increased over 4 years.

Odds of mortality were higher among ST-segment elevation MI patients who had than peers receiving emergent coronary angiography. The former was a group of inherently higher-risk patients, however, the meta-analysis showed. (Circulation: Cardiovascular Quality and Outcomes)

Pulmonary vein stenosis was less likely with after catheter ablation for atrial fibrillation compared to percutaneous transluminal balloon angioplasty alone, according to operators at a German center. (JACC: Cardiovascular Interventions)
