Cardiotoxicity, including heart failure, thromboembolic events, and myocardial ischemia, is a concern for cardiologists and oncologists. The most frequently involved drugs are anthracyclines. We report an episode of coronary spasm due to vincristine, a vinca alkaloid, in a 49-year-old man treated for a diffuse undifferentiated carcinoma. The patient suffered recurrent episodes of typical chest pain with ST-elevation in the inferior area. Coronary spasm was confirmed by an angiogram, which showed normal coronary arteries. No recurrence occurred with the medical management. Coronary spasm induced by vincristine is a newly described facet of chemotherapy-related cardiotoxicity.

Diffuse Coronary Vasospasm After Zone 2 Debranching and Antegrade TEVAR.
Ann Thorac Surg Short Rep

Coronary vasospasm involves constriction of the coronary arteries and has been described after manipulation of the coronary arteries (ie, after stenting or bypass grafting). This report details the case of a 57-year-old man who presented with an endoleak after thoracic endovascular aortic repair. He underwent a frozen elephant trunk procedure and postoperatively had diffuse coronary vasospasm, demonstrated on pre- and post-vasospasm cardiac catheterization.

Background: Trans-radial coronary angiogram (TR-CAG) has gained popularity due to lower complication rates compared to transfemoral access. Operators can use either conventional catheters, such as Judkins, or single dedicated catheters, such as Tiger-II. This meta-analysis compared the safety and efficacy of Tiger-II versus Judkins catheters in TR-CAG.

Catheter ablation is a widely used treatment modality for various cardiac tachyarrhythmias, including atrial and ventricular arrhythmias. Although it is generally considered safe, the procedure carries potential complications, with coronary artery injury being one of the most significant. The aim of this systematic review was to assess the incidence, mechanisms, contributing factors, diagnostic strategies, and preventive measures related to coronary artery injury in patients undergoing catheter ablation, including radiofrequency catheter ablation, cryoablation, and pulsed-field ablation.

It is well understood that cancer therapies including chemotherapy, tyrosine kinase inhibitors, immune checkpoint inhibitors, and radiation can increase the risk of cardiovascular disease in patients with cancer. This can manifest as a multitude of pathologies including left ventricular dysfunction, myocarditis, cardiomyopathy, accelerated atherosclerosis, and coronary vasospasm. Multimodal cardiac imaging plays a critical role in diagnosing such pathologies by relying on noninvasive tools including echocardiograms, cardiac magnetic resonance imaging, positron emission tomography, single-photon emission computed tomography, and coronary computed tomography angiography.
