The optimal management of coronary intramural hematoma has not been defined. We described a case in which coronary occlusion developed due to an intramural hematoma after percutaneous coronary intervention for mid left circumflex artery (LCX). Intravascular ultrasound (IVUS) demonstrated the progression of the intramural hematoma and a totally compressed true lumen. Our approach was based on fenestration with a scoring balloon (NSE Alpha, Goodman, Japan), which allowed the deployment of an additional stent to be avoided. In conclusion, this management can be effectively and safely performed.

Guiding Catheter

A bidirectional approach for percutaneous coronary intervention for chronic total occlusion (CTO-PCI) using ipsilateral collaterals with a single guiding catheter limits procedural choices. The CTO of the left circumflex artery with ipsilateral collateral artery was treated by the bidirectional approach using a single guiding catheter. While the retrograde wire directly crossed the CTO lesion, the microcatheter could not pass the CTO lesion despite the conventional strategies. Therefore, we performed the wire rendezvous and chasing wire techniques. The wire rendezvous technique enables deeper retrograde guidewire progression, and the antegrade microcatheter can reach the CTO entry. The chasing wire technique enables the antegrade guidewire to pass the route made by the retrograde guidewire. These techniques might offer a possible solution for bidirectional CTO-PCI using a single guiding catheter. However, this technique should be considered as a last resort because of the risk of rapid reocclusion.

Abstract Background Iatrogenic acute aortic dissection (AAD) caused by cardiovascular intervention is rare. Also rare is spontaneous coronary artery dissection (SCAD), a form of acute coronary syndrome, which develops in relatively young women without coronary risk factors. We encountered type A iatrogenic AAD caused by an intervention for SCAD. Case presentation A 53-year-old woman was brought to our hospital after cardiopulmonary resuscitation. She was diagnosed with acute coronary syndrome caused by SCAD, and percutaneous coronary intervention was carried out on her distal left anterior descending artery. The dissection proceeded to the proximal left anterior descending artery and left main coronary artery trunk, so additional percutaneous coronary intervention was performed on the left circumflex artery. After the intervention, type A AAD occurred with a primary entry tear from the left main coronary artery trunk, and computed tomography showed a type A AAD of the aortic arch. We performed emergency ascending aorta replacement and coronary artery bypass grafting to the left anterior descending artery and left circumflex artery. The patient had an uneventful recovery after the operation and was discharged on postoperative day 25. Conclusion To our knowledge, this is the first report of an iatrogenic AAD caused by percutaneous coronary intervention for SCAD.

Dextrocardia is a rare congenital anomaly of development characterized by a mirror- image position of the heart. Unlike dextrocardia with situs solitus or ambiguus, the coincidence of congenital heart disease is relatively low among dextrocardic patients with situs inversus. However, patients with dextrocardia may suffer from coronary heart disease as do people with normally positioned hearts. Few cases of coronary angiography and percutaneous coronary intervention in patients with dextrocardia have been reported. This is a case of a 48-year-old male patient with dextrocardia who developed unstable angina and was able to undergo diagnostic catheterization and percutaneous coronary intervention. We successfully performed percutaneous coronary angioplasty followed by coronary stenting to the left circumflex artery (LCX) and described our experience in the selection of the guiding catheters (standard preformed catheters), angiographic image acquisition (mirror image views with subtle modification) and coronary catheter engaging techniques (opposite-direction catheter rotations).
