Acute coronary occlusion after surgical replacement of the aortic valve treated with emergency off-pump coronary artery bypass grafting.

J Card Surg 2021 Jun 18. Epub 2021 Jun 18.

Bristol Heart Institute, University Hospital of Bristol and Weston NHS Foundation Trust, Bristol, UK.

Acute coronary occlusion after surgical replacement of the aortic valve is a rare but potentially fatal event. Due to its rarity, there is no univocal treatment with the percutaneous approach being the most commonly used for its promptness and ease of use. Only a few cases have been treated with coronary artery bypass grafting (CABG) and, to the best of our knowledge, none has been reported with the use of off-pump CABG (OPCABG). Read More

Acute coronary syndrome because of a scorpion sting in a patient with chronic coronary syndrome: A case report and review of the literature.

Turk Kardiyol Dern Ars 2021 Jun;49(4):328-333

Department of Cardiology, Balıkesir University School of Medicine, Balıkesir, Turkey.

The occurrence of acute coronary syndrome (ACS) following a scorpion sting has been very rarely reported in literature, and most of the cases presented had a normal coronary angiogram. The possible pathogenetic mechanisms include imbalance in blood pressure and coronary spasm caused by a combination of sympathetic excitation with subsequent thrombosis of coronary vessels developed after the release of vasoactive, inflammatory, and thrombogenic substances contained in the scorpion venom. In this report, we present a case of a scorpion sting complicated by ACS, called Kounis syndrome (KS). Read More

Optimizing the diagnosis and assessment of chronic thromboembolic pulmonary hypertension with advancing imaging modalities.

Pulm Circ 2021 Apr-Jun;11(2):20458940211007375. Epub 2021 May 24.

Cardiothoracic Imaging, University of California San Diego, La Jolla, CA, USA.

Imaging is key to nearly all aspects of chronic thromboembolic pulmonary hypertension including management for screening, assessing eligibility for pulmonary endarterectomy, and post-operative follow-up. While ventilation/perfusion scintigraphy, the gold standard technique for chronic thromboembolic pulmonary hypertension screening, can have excellent sensitivity, it can be confounded by other etiologies of pulmonary malperfusion, and does not provide structural information to guide operability assessment. Conventional computed tomography pulmonary angiography has high specificity, though findings of chronic thromboembolic pulmonary hypertension can be visually subtle and unrecognized. Read More
