Objectives. This study aimed to investigate the optimal jailed balloon inflation in the side branch during the modified jailed balloon technique for bifurcated lesions. Background. The modified jailed balloon technique is one of the effective techniques to minimize the emergence of side branch (SB) compromise by preventing plaque or carina shifting during a single stent strategy in the main vessel with provisional SB treatment. However, there are no detailed studies on the method of optimal jailed balloon inflation. Methods. We analyzed 51 consecutive patients who underwent percutaneous coronary intervention (PCI) for bifurcated lesions with a modified jailed balloon technique between September 2018 and December 2020. These 51 patients were divided into two groups according to the magnitude of inflation pressure of the jailed balloon: a higher pressure (HP) group and lower pressure (LP) group. Results. No significant differences in procedural outcomes were observed between the two groups. The findings of SB compromise were relatively common with our procedure (30.0% in the HP group; 33.3% in the LP group). The patterns of SB compromise such as dissection or stenosis increase were observed at similar frequencies between them. In particular, SB dissection was noted in the SB lesion with some plaque burden, irrespective of the magnitude of the jailed balloon inflation pressure. Univariate analysis showed that calcification in the main vessel and SB lesion length was significantly associated with SB compromise. Finally, all PCI procedures were successfully completed without any provisional stent deployment in SB. Conclusions. We speculate that lesion characteristics rather than the PCI procedural factors may be critical determinants to cause SB compromise.

Background: Kissing Balloon Inflation (KBI) technique was the first technique for percutaneous intervention in bifurcation lesions. It's the standard strategy in the two-stent procedure. Its benefit in one-stent approach remains uncertain. Several trials comparing KBI strategy with the No-KBI strategy in one-stent technique did not show any advantages in the clinical outcome. Clinical outcome and the follow up of ischemic symptoms is a useful method to compare the effectiveness of both strategies. Aims: To study the short-term clinical outcome (3and 6 months) of provisional versus routine kissing‑balloon technique after main vessel stenting for coronary bifurcation lesions. Patients and Methods: The study included sixty consecutive patients. They were randomized to receive different side branch (SB) intervention strategies: group I (provisional final kissing balloon inflation group - PFKBI) (FKBI only when SB Flow less than TIMI 3) and group II (routine final kissing balloon inflation group – RFKBI). Results: 1- Dissection of side branch and conversion to two stent strategy was significantly higher in PFKBI group (14,3%) than in RFKBI group (0) 2-The amount of dye, total procedure time and time of admission was significantly higher in RFKBI group. 3-Chest pain immediately after the procedure was significantly higher in PFKBI group while at 3 and 6 months follow up no significant difference between both groups was noticed. 4- MACE, target lesion revascularization (TLR) and stent thrombosis were similar between both groups at 3 and 6 months. Conclusions: Main vessel stenting with and without final kissing balloon dilatation was associated with favorable and similar 3 and 6-month clinical outcomes.

Coronary bifurcations are prone to the development of atherosclerosis. They pose technical difficulties for angioplasty treatment and are a predictor of stent thrombosis and restenosis. Treatment of coronary bifurcations is still subject to debate, especially when the side branch (SB) is large, not easily accessible and narrowed by a long lesion. There is currently no indexed treatment for this type of lesion (Medina classification), as the strategy of provisional SB stenting with drug-eluting stents (DES) has proved to be equally efficient as the dualstent technique. Complex techniques are associated with poor outcome in certain lesion types, such as T-stenting when the angle between the two distal branches is small or the crush and culotte technique in the presence of an open angle. Provisional SB stenting may be used when primary dual stenting is required, with a low risk of failure provided that the following guidelines are implemented: stenting of the main branch through the protected SB with a stent diameter adapted to the distal main branch, immediate optimisation of the proximal stent segment (Finet’s law), guidewire exchange, kissing balloon inflation with non-compliant balloons selected according to the diameter of the distal branches and T-stenting of the SB before final kissing inflation.

Abstract Background Provisional side branch (SB) stenting is correlated with target-vessel myocardial infarction (TVMI) in patients with coronary bifurcation lesions. However, the underlying mechanisms remain unknown. Objectives We aimed to determine the correlation of SB lesion length with vulnerable plaques using optical coherence tomography (OCT) and TVMI in patients with coronary bifurcation lesions treated by a provisional approach. Methods A total of 405 patients with 405 bifurcation lesions who underwent pre-PCI OCT imaging of both main vessel (MV) and SB was prospectively enrolled. Patients were defined as Long-SB lesion (SB lesion length ≥10 mm) and Short-SB lesion (SB lesion length <10 mm) groups according to quantitative coronary analysis and were also stratified by the presence of vulnerable plaques based on OCT findings. The primary endpoint was the occurrence of TVMI after provisional stenting at one-year follow-up. Results 178 (43.9%) patients had long SB lesions. Vulnerable plaques predominantly localized in the main vessel (MV) and more frequently in the Long-SB lesion group (42.7%) compared to 24.2% in the Short-SB lesion group (p<0.001). At one-year follow-up after provisional stenting, there were 31 (8.1%) TVMIs, with 11.8% in the Long-SB lesion group and 4.4% in the Short-SB lesion group (p=0.009), leading to significant difference in target lesion failure between two groups (15.2% vs. 6.6%, p=0.007). The rate of cardiac death, revascularization, and stent thrombosis was comparable between study groups. By multivariate regression analysis, long SB lesion length (p=0.011), presence of vulnerable plaques in the polygon of confluence (p=0.001), and true coronary bifurcation lesions (p=0.004) were three independent factors of TVMI. Conclusions Long-SB lesion length with MV vulnerable plaques predict increased TVMI after provisional stenting in patients with true coronary bifurcation lesions. Further study is warranted to identify the better stenting techniques for coronary bifurcation lesions with long lesion in the SB Kaplan-Meier survival curve Funding Acknowledgement Type of funding source: Foundation.

Percutaneous Coronary

During percutaneous coronary interventions (PCI), good lesion preparation with adequate balloon predilatation is a fundamental step before stent deployment in order to achieve optimal stent expansion and favourable long-term outcomes post PCI. During PCI, inadvertent vessel tearing can occur, resulting in coronary dissections and formation of intramural haematomas. The latter might be associated with compression of the vessel lumen and significant compromise of the coronary blood flow leading to myocardial ischaemia and infarction. Herein, we present a case of intramural haematoma that occurred after PCI of the left anterior descending artery resulting in occlusion of the vessel and the subsequent use of a cutting balloon inflation technique to resolve the haematoma and restore the normal coronary blood flow.

AbstractConsiderable progress has been made in the treatment of coronary bifurcation stenosis. Anatomical characteristics of the vessel and lesion, however, fail to give information about the functional significance of the bifurcation stenosis. To the best of our knowledge, there is no study that systematically establishes the baseline functional significance of coronary stenosis and its effect on procedural and clinical outcomes. Patients with significant angiographic bifurcation lesions defined as diameter stenosis > 50% in main vessel and/or side branch were included. FFR was performed in main vessel (MV) and side branch (SB) before and after percutaneous coronary intervention (PCI). 169 patients from Fiesta study (derivation cohort) and 555 patients from prospective bifurcation registry (clinical effect cohort) were analyzed to validate angiographic prediction score (BFSS) used to determine the potentially functional significance of coronary bifurcation stenosis. Bifurcation functional significance score (including the following parameters—SYNTAX ≥ 11, SB/MB BARI score, MV %DS ≥ 55%, main branch (MB) %DS ≥ 65%, lesion length ≥ 25 mm) with a maximum value of 11 was developed. A cut-off value of 6.0 was shown to give the best discriminatory ability—with accuracy 87% (sensitivity 77%, specificity 96%, p < 0.001). There was also a significant difference in all-cause mortality between patients with BFSS ≥ 6.0 vs. BFSS < 6.0–25.5% vs. 18.4%, log-rank p = 0.001 as well as cardiac mortality: BFSS ≥ 6.0 vs. BFSS < 6.0–17.7% vs. 14.5%, log-rank (p = 0.016). The cardiac mortality was significantly lower in patients with smaller absolute SB territory, p = 0.023. An angiographic score (BFSS) with good discriminatory ability to determine the functional significance of coronary bifurcation stenosis was developed. The value for BFSS ≥ 6.0 can be used as a discriminator to define groups with higher risk for all-cause and cardiac mortality. Also, we found that the smaller side branches pose greater mortality risk.

The Difference

AbstractThe coronary bifurcation intervention varies among countries due to the differences in assessment of lesion severity and treatment devices. We sought to clarify the difference in basic strategy between South Korea and Japan. A total of 19 and 32 experts from Korean (KBC) and Japanese Bifurcation Clubs (JBC), respectively, answered a survey questionnaire concerning their usual procedure of coronary bifurcation intervention. JBC experts performed less two-stent deployment in the left main (LM) bifurcation compared to KBC experts (JBC vs. KBC: median, 1–10% vs. 21–30%, p < 0.0001) instead of higher performance of side branch dilation after cross-over stenting in both LM (60% vs. 21%, p = 0.001) and non-LM bifurcations (30% vs. 5%, p = 0.037). KBC experts more frequently performed proximal optimization technique (POT) in non-LM bifurcation (41–60% vs. 81–99%, p = 0.028) and re-POT in both LM (1–20% vs. 81–99%, p = 0.017) and non-LM bifurcations (1–20% vs. 81–99%, p = 0.0003). JBC experts more frequently performed imaging-guided percutaneous coronary intervention, whereas KBC experts more often used a pressure wire to assess side branch ischemia. JBC experts used a rotablator more aggressively under the guidance of optical coherence tomography. We clarified the difference in the basic strategy of coronary bifurcation intervention between South Korea and Japan for better understanding the trend in each country.

Timely recognition of the characteristic electrocardiographic pattern of de Winter syndrome is important for providing immediate reperfusion therapy for acute anterior myocardial infarction. In this case, an electrocardiogram showed 1- to 3-mm upsloping ST-segment depression at the J point in leads V1 to V6, with loss of R wave progression in leads V1 to V4. Urgent angiography showed occlusion of the proximal left anterior descending coronary artery and 70% stenosis in the ostial first diagonal branch (Medina type 1.1.1.). For this bifurcation lesion, we successfully performed a modified jailed-balloon technique to protect the side branch during percutaneous coronary intervention stenting. Thereafter, thrombolysis in myocardial infarction 3 flow was restored in both branches. This modified jailed-balloon technique is safe and effective in stent placement for de Winter syndrome without any loss of side branches.

Coronary Bifurcation

Percutaneous coronary intervention (PCI) of bifurcation lesions is a technical challenge associated with high risk of adverse events, especially in primary PCI. The aim of the study is to analyze long-term outcomes after PCI for coronary bifurcation in acute myocardial infarction (AMI). The outcome was defined as the rate of major adverse cardiac event related to target lesion failure (MACE-TLF) (death-TLF, nonfatal myocardial infarction-TLF and target lesion revascularization (TLR)) and the rate of stent thrombosis (ST). From 306 patients enrolled to the registry, 113 were diagnosed with AMI. In the long term, AMI was not a risk factor for MACE-TLF. The risk of MACE-TLF was dependent on the culprit lesion, especially in the right coronary artery (RCA) and side branch (SB) with a diameter >3 mm. When PCI was performed in the SB, the inflation pressure in SB remained the single risk factor of poor prognosis. The rate of cumulative ST driven by late ST in AMI was dependent on the inflation pressure in the main branch (MB). In conclusion, PCI of bifurcation culprit lesions should be performed carefully in case of RCA and large SB diameter and attention should be paid to high inflation pressure in the SB. On the contrary, the lower the inflation pressure in the MB, the higher the risk of ST.

Abstract Background Bifurcation lesions are account for relatively high incidence of adverse events, especially in serious calcification and distort lesions during bifurcation stenting. Purpose Based on Saito's modified jailed balloon technique (M-JBT, Shigeru Saito, Modified jailed balloon technique for bifurcation lesions, Catheter Cardiovasc Interv. 2018; 92:E218–E226), fully dilatation with modified balloons was performed on calcification lesion in main branch, to observe if this combination method will facilitate bifurcation lesions stenting procedure. Methods For M-JBT, we followed Saito's technique. Basically, a jailed balloon (JB) is introduced into the side branch (SB), while a stent is placed in the main branch (MB) as crossing SB. The size of the JB is half of the MB stent size. While the proximal end of JB attaching to MB stent, both stent and JB are simultaneously inflated with same pressure. Kissing balloon dilatation (KBD) and/or T and protrusion (TAP) stenting are applied as needed. Modified balloons are performed as severe calcification presented in MB. Results More than 50 patients and 60 bifurcations (both for selective and primary cases) underwent percutaneous coronary intervention (PCI) using this combined technique since November 2018. Procedure success was achieved in all cases. KBD was performed for a few lesions and TAP stenting was employed for 1 lesion. Occlusion of SV was not observed in any of the patients. Illustration cases and prodedure Conclusions Saito's modified jailed balloon technique is safe and effective method in bifurcation stenting. Combined with modified balloons is an effective method when severe calcification presented in bifurcation lesions, especially in distort lesion (main branch or side branch) and poor position visualization situations when rewire is difficult in traditional JBT procedure.
