Clinical Information

Relevant Clinical History and Physical Exam

 A 70 years male knowncase of hypertension, hyperlipidemia & case IHD, PCI pLAD & RCA 2019, recentNSTEMI coronary angiogram showed distal LMS stenosis, ostial LCX and LAD severedisease & ISR LAD & RCA. Counselled for CABG, but not keen, referred tous for high risk multivessel angioplasty angioplasty. Echo showed EF 41%.

Relevant Catheterization Findings

Tortous RCA, difficult witing, managed to pass prediltationballoon  after straightening  the artery with guide plus and grand slam wire.Predilated with Minitrek 2.0x 10, IVUS showed Severe In-Stent Restenosis,old stent is under sized,2.5 stent. Vessel size 3.0-3.5 distally, heavy plaqueburden.Predilated with Wedge NC 2.5 x 10, & NC Emerge 3.0 x 8mm at ostium Stented in stent withSynergy 3.0 x 48mmPostdilated with NC Emerge 3.5 x 12mm & 4.0/12 proximally

Case Summary

Coronary artery tortuosity is a common angiographic finding and has been associated with difficulty in passing wire, balloon and stents and also with  adverse events after PCIThe use of adjuvant stool such as super stiff wire, arrow sheath to over come femoral tortuosity and guideliner and grand Slam wire for coronary .The usefulness of intravascular imaging to understand ISR .
