30-day outcome after percutaneous coronary angioplasty in nonagenarians: feasibility and specific considerations in different clinical settings.

Background: Nonagenarians have been systematically excluded from randomized trials dealing with invasive coronary strategies, resulting in a lack of evidence-based guidelines regarding the optimal approach in this population.

Aim: To describe the clinical and procedural characteristics and outcomes of patients 90 years of age or older who were treated with percutaneous coronary interventions (PCI).

Methods: We evaluated the 30-day outcomes of patients 90 years or older who underwent PCI at our institution, comparing the ST-segment elevation myocardial infarction (STEMI) subgroup with the non-STEMI/unstable angina (UA) and stable angina (SA) subgroups, who had been referred for coronary angiography.

Optimization of myocardial perfusion after primary coronary angioplasty following an acute myocardial infarction. Beyond TIMI 3 flow.

Unlabelled: Primary angioplasty has become the preferred therapeutic modality in patients with acute myocardial infarction (AMI). Despite restoration of antegrade epicardial flow by mechanical reperfusion therapy, angiographically assessed microvascular function and myocardial reperfusion (blush) allows for the stratification of patients with epicardial TIMI 3 flow into different strata of survival. Despite this fact, the best approach to achieving good myocardial blush has not yet been established.

Anglographic functional characterization of the coronary sinus.

Background: Coronary sinus is a venous conduit with dynamic and unclear function with regard to coronary circulation.

Objectives: To describe the dynamic changes of the coronary sinus during the cardiac cycle.

Methods: The angiographic feature of the coronary sinus was evaluated in 30 patients undergoing diagnostic and therapeutic coronary angiography.
