Sequential vs. kissing balloon angioplasty for stenting of bifurcation coronary lesions
Key result
Simultaneous (kissing) balloon angioplasty significantly reduced the rate of permanent or transient side-branch compromise compared to sequential angioplasty (0% vs 33%; P=0.003).
Why the study?
Does simultaneous balloon angioplasty (kissing balloon technique) improve immediate and long-term clinical and angiographic results compared to sequential balloon angioplasty in patients with symptomatic bifurcation coronary lesions?

Implication
Kissing balloons may limit side-branch compromise in bifurcation PCI; leaves open clinical benefit and requires randomized confirmation.

Type
Cohort (n=59)
Structured PICO
Does simultaneous balloon angioplasty (kissing balloon technique) improve immediate and long-term clinical and angiographic results compared to sequential balloon angioplasty in patients with symptomatic bifurcation coronary lesions?
P
Population
59 patients with symptomatic type III bifurcation coronary lesions undergoing stenting, followed for 6 months.
E
Exposure
Simultaneous balloon angioplasty (kissing balloon technique) with mandatory main-vessel stent placement
C
Comparator
Sequential balloon angioplasty with mandatory main-vessel stent placement
O
Outcome
Immediate and long-term clinical and angiographic results (procedural success, repeat target vessel revascularization due to restenosis, side-branch compromise rate)composite
Main Result
Absolute Event Rate: 0% vs 33%
p-value: p=0.003
Kissing balloon angioplasty reduces the rate of transient side-branch occlusion compared to sequential angioplasty but does not improve immediate or long-term clinical outcomes for stenting of bifurcation lesions.
Cite This Study
Brueck et al. (2002) conducted a cohort in Symptomatic bifurcation coronary lesions type III (n=59). Simultaneous balloon angioplasty (kissing balloon technique) vs. Sequential balloon angioplasty was evaluated on Permanent or transient side-branch compromise rate (TIMI flow < 3) (p=0.003). Simultaneous (kissing) balloon angioplasty significantly reduced the rate of permanent or transient side-branch compromise compared to sequential angioplasty (0% vs 33%; P=0.003).
