Impact of post physiological assessment after treatment for de novo coronary lesions using drug-coated balloons.

Background: Acute physiological changes after balloon angioplasty are very important because of acute recoil and dissection. However, serial physiological assessments after drug-coated balloons (DCB) have not been investigated.

Methods: This prospective observational single-center study evaluated 50 lesions that underwent optical coherence tomography (OCT)-guided percutaneous coronary intervention (PCI) with DCB and a 9-months angiographical and OCT follow-up.

Healed plaque erosion as a cause of recurrent vasospastic angina: a case report.

Background: Recurrent vasospastic angina sometimes occurs. Fresh thrombi have been known to arise without plaque rupture at coronary spasm sites due to blood flow stagnation and intimal erosion caused by vasospasms. The relationship between recurrence of vasospastic angina and thrombus formation remains unclear.
