Clinical Information

Patient initials or Identifier Number

Madam ZR

Relevant Clinical History and Physical Exam

A 48-year-old with long-standing poorly controlleddiabetes mellitus, hypertension, dyslipidaemia, and 3 vessels coronary arterydisease was referred for progressive angina. She also had symptoms of orthopnoeaand bilateral leg swelling. Clinically she was in warm and wet decompensated heartfailure requiring oxygen supplement 3 L/minute via nasal prong. Heart Team meetingdiscussion decided not to surgical intervene due to poor vessel targets. 

Relevant Test Results Prior to Catheterization

The electrocardiogram showed ST-depression at lead I, aVL,V5, and V6 with poor R-wave progression. The NT-proBNP reported was 2361 pg/ml andTroponin T of 19 ng/L. Her HBA1c was 11.2 %. Otherwise, routine blood testsprior to catheterization procedure were unremarkable. Cardiac MRI revealed a leftventricular ejection fraction of 15% and non-viable mid to apical rightcoronary artery territories on gadolinium study. There was an atrial septaldefect causing right ventricular dilatation.

Relevant Catheterization Findings

Coronaryangiogram revealed: Severe stenosis at distal left main; diffuse subtotalstenosis of the left anterior descending artery; severe stenosis at the ostialleft circumflex artery and chronic total occlusion at mid-right coronary artery.

Interventional Management

Procedural Step

PCI to left circumflex artery into the left main artery. Rightfemoral artery access for PCI with Intra-Aortic Balloon Pump (IABP) supportfrom left femoral. Left main was engaged using guiding catheter JL 3.5 6Fr.Wired distal left circumflex with workhorse Runthrough wire. IVUS run for vesselsize, length, and lesion characterization. Pre dilated with a 2.5 x 15 mm balloonwith pressure up to 16 ATM. Sion blue was used as a second wire for support.  A stent 3.0 x 28 mm deployed from left circumflexinto the left main artery with a pressure of 11 ATM. Stent was post dilated withan NC balloon 3.5 x 15 mm. 2nd IVUS run showed well-apposed stentand no complications i.e edge dissection or hematoma.

Case Summary

The evolution of percutaneous coronary interventions (PCI)has been remarkable during the past decades. The never-ending research,innovation, development of new techniques, and new device technologies improvethe success rates. This has resulted in sicker patients with more complexlesions that can now be treated by PCI.  Oursubject was a high-risk candidate with worsening angina, heart failure, and refractoryto medical therapy. It is of utmost essential to discuss the risks and benefitsof the intervention with the patient, family, and hospital personnel. Immediateappropriate measures can be taken before and during the high-risk PCI tominimize the risk of major adverse event.
