A 46-year-old man underwent coronary angiography for stable angina. He developed inferior ST-segment myocardial infarction during the angiography. Intravascular ultrasound (IVUS) findings suggested coronary vasospasm. Intracoronary administration of isosorbide dinitrate restored the coronary flow. This case illustrates the essential role IVUS imaging played in establishing the diagnosis of catheter-induced coronary vasospasm.

Background: High-risk pulmonary embolism (PE) is associated with significant mortality. Thrombolysis is the therapy of choice, while interventional thrombectomy may be a helpful strategy in case of contraindications or failed thrombolysis. However, the procedure may be complicated by catheter-induced embolization of clots and/or haemodynamic compromise.

A 48-year-old male with a history of hyperlipidemia presented to the emergency department with chest pain. Electrocardiographic abnormalities indicated an acute coronary syndrome. Urgent coronary angiography revealed nondominant right coronary artery (RCA) occlusion.

Our case involves a 29-year-old postpartum woman who presented with severe substernal chest pain eight days after an emergency cesarean section for pregnancy-associated hypertension. Electrocardiography showed ST elevation in the inferior and posterior leads, and coronary angiography revealed a spontaneous dissection in the left circumflex artery (LCx) with an intramural hematoma, alongside a dissection of the right coronary artery (RCA) extending from the ostium to the mid-vessel.

Many patients with premature ventricular complexes (PVCs) do not experience symptoms. However, for those with frequent or symptomatic PVCs, medical interventions are available. If medications fail, radiofrequency catheter ablation may be performed.

Coronary atherosclerotic lesions at the ostium and proximal coronary arteries pose significant challenges in percutaneous coronary interventions (PCI), especially in the left main coronary artery (LMCA). Guide catheter-induced damage can lead to severe complications such as vessel dissection or myocardial infarction. Ostial stent placement with drug-eluting stents offers mechanical support and reduces restenosis but is technically challenging due to the anatomical complexity of the ostium.
