Insights
This case study highlights a scaffold-minimizing hybrid strategy for complex calcified coronary artery disease in frail patients. Drug-coated balloons (DCBs) effectively managed acute complications, avoiding extensive stenting.
Area of Science:
- Cardiology
- Interventional Cardiology
Background:
- Complex coronary artery disease (CAD) in frail patients presents a challenge, requiring a balance between procedural success, safety, and minimizing permanent metallic implants.
- Frail patients often have multiple comorbidities, increasing procedural risks.
Background:
Complex coronary disease in frail patients requires balancing procedural efficacy, safety, and permanent metallic implantation.
Case Summary:
A 76-year-old frail woman presented with non-ST-segment elevation acute coronary syndrome and triple-vessel disease, including a calcified left anterior descending artery-diagonal bifurcation, circumflex culprit lesion, and right coronary artery chronic total occlusion. After circumflex stenting, the bifurcation lesion underwent extensive preparation with balloons and intravascular lithotripsy. The procedure was complicated by acute diagonal occlusion with hemodynamic instability. Flow was restored using drug-coated balloons (DCBs) in both branches, avoiding complex stenting. At a staged procedure, the right coronary artery chronic total occlusion was recanalized with a hybrid DCB and focal stent strategy. Repeat angiography demonstrated positive remodeling.
Discussion:
This case illustrates a scaffold-minimizing hybrid strategy for complex calcified coronary disease.
Take-Home Messages:
DCBs may be effective in selected high-risk patients. In selected cases, acute flow compromise during complex percutaneous coronary intervention can be managed with DCB angioplasty without resorting to bailout stenting.

Normal blood pressure is 120/80 mm Hg. Elevated blood pressure is 120-129/under 80 mm Hg. Hypertension, warranting treatment at 130/80 mm Hg, is often asymptomatic and can lead to severe cardiovascular events, aneurysms, peripheral arterial disease, chronic renal disease, or cardiac...
