Our study presented the long-term outcomes of coronary stenting and predictors of two-year outcomes in octogenarian patients with acute coronary syndrome. A total of 366 patients with STEMI, NSTEMI and unstable angina undergoing percutaneous coronary intervention (PCI). Results were assessed at a median follow up of 20 months. Hospital mortality in the group of patients older than 80 years was 8% and long-term mortality 21%. Chronic renal failure, cardiogenic shock, multi-vessel coronary disease, ejection fraction less than 35, left main coronary artery lesion were independent predictors of mortality. The best prognosis corresponded to those drug-eluting stents use, radial access and GP IIb/IIIa use in patients with ST-segment elevation myocardial infarction. Progression of cardiac and renal failure were the main causes of death during this period. Our results suggested that percutaneous coronary interventions in octogenarian patients with acute coronary syndrome was associated with good clinical and long-term outcomes. DES use, radial access and GP IIb/IIIa use in patients with ST-segment elevation myocardial infarction were associated with improved all-cause mortality in our population.

We present a case of a 52-year-old male with no known past medical history who presented to an outside hospital with acute chest pain. Initial workup revealed anteroseptal ST-elevation myocardial infarction (STEMI) for which the patient was transferred to our facility for emergent percutaneous coronary intervention (PCI). However, the patient's hospital course revealed numerous confounding pathologies that can also present as STEMI, including transthoracic echocardiogram (TTE) abnormalities consistent with takotsubo cardiomyopathy (TCM) as well as myocardial bridging presenting as post-PCI STEMI in the setting of nitroglycerin use.

GECs are used for stent delivery into the coronary arteries of patients with difficult anatomy due to tortuosity, calcification, or chronic total occlusion (CTO) vessels. Stent and balloon placement has become challenging in patients with increasing lesion complexity due to tortuosity, vessel morphology, length of the lesion, and respiratory movements.

A female patient in middle childhood was diagnosed with coarctation of the aorta at one month of age and underwent a successful cortectomy. At 11 years old, she developed re-coarctation, which was managed through interventional cardiology. Shortly after the procedure, she experienced a sudden and severe clinical decline, presenting with hypoperfusion of the lower extremities, gastrointestinal bleeding, acute kidney injury, and pancreatitis.

Background: Type 2 diabetes mellitus (T2DM) patients with small-diameter stents (SDS), that are equal to or less than 2.5 mm in diameter, face increased risks of restenosis and complications. This study aimed to evaluate the 1-year follow-up to assess the rate of major adverse cardiac events (MACE) and bleeding risk between ticagrelor and clopidogrel in T2DM patients after SDS implantation.

Background: Percutaneous mechanical aspiration thrombectomy is increasingly being employed as a less invasive alternative for managing right heart masses, including clot in transit.
Aims: We aimed to analyze trends in the use of catheter-directed aspiration (CDA) for right heart masses. Additionally, we analyzed in-hospital outcomes of percutaneous versus surgical approaches for patients with CIT and PE.
