Abstract Background Successful recanalisation of percutaneous coronary intervention for chronic total occlusion lesions has been associated with improved survival. Purpose This study aimed to assess the impact of successful percutaneous coronary intervention for chronic total occlusion lesions on the long-term outcome of patients with impaired and preserved left ventricular ejection fraction (LVEF). Methods The study sample consisted of 842 consecutive patients (928 chronic total occlusion lesions) undergoing percutaneous coronary intervention at our institution between October 2005 and December 2009. We divided them into 3 groups by the degree of LVEF: less than 40% (severely reduced LVEF, n=140), 40% to 59% (moderately reduced LVEF, n=470), and 60% and above (normal LVEF, n=232). We evaluated mortality during the 10-year follow-up period the basis of procedural success and failure. Results The overall procedural success rate was 89.1%. Median follow-up duration was 7.9 years. The 10-year cumulative incidences of cardiac death in each degree of LVEF are shown in the Figure. Conclusions Successful recanalisation for chronic total occlusion lesions in patients with impaired LVEF may be associated with reduced cardiac mortality.

St Elevation

Tindakan Primary Percutaneous Coronary Intervention (PPCI) untuk pasien sindrom koroner akut (SKA) dengan ST elevasi (STEMI=ST elevation myocardial infarction) telah berjasa banyak dalam menurunkan mortalitas. Namun kerusakan jaringan miokard pasca PPCI tetap terjadi, akibat iskemia yang telah berlangsung sebelum reperfusi berhasil, atau kerusakan jaringan miokard akibat cedera reperfusi. Hal tersebut menimbulkan konsekuensi morbiditas akibat SKA berupa gagal jantung. Sehingga dikhawatirkan bila SKA tidak dicegah, di masa yang akan datang akan timbul epidemi gagal jantung. Oleh sebab itu strategi pencegahan terjadinya SKA perlu menjadi pengetahuan dasar bagi seluruh dokter spesialis jantung dan pembuluh darah (SpJP) agar epidemi gagal jantung dapat dicegah.Strategi pencegahan SKA tetap memegang 5 prinsip:1. Health Promotion2. Primary Prevention3. Early Detection and Prompt Treatment4. Secondary Prevention5. RehabilitationPoin pertama dan kedua dilakukan langsung ke tengah masyarakat di luar klinik atau rumah sakit, mulai dari poin ke-tiga, yaitu deteksi dini, dilakukan dalam praktek klinik.

Procedural Success

Background. Despite constant technical advances, percutaneous coronary intervention (PCI) of chronic total occlusion (CTO) remains a challenge with procedural success ranging from 65 to 85% in high volume center. MSCT provides information which cannot be obtained with conventional coronary angiography such as: plaque constitution, calcifications and distribution, route and distal run off. A better knowledge of these parameters may influence the approach to such complex PCI, optimize procedural strategy and success. The aim of our study was to evaluate the usefulness of cardiac CT before PCI of CTO. Methods . All patients with CTO underwent 64-slice CT before the scheduled PCI. We used a scan protocol with 64±0.625mm slice collimation (pitch 0.2), 350 ms (General Electric Lihgtspeed VCT) and 420 ms (Philips Brillance) rotation time and simultaneous (ECG) gating. Patients with heart rates above 65 bpm received intravenous beta-blockade. All CT examinations were performed with retrospective electrocardiogram gating. Exclusion criteria were atrial fibrillation and creatinemia >140 μmol/l. Results . Sixty patients were included in the study. Mean age was 63.58.5 yrs, 90% were male. On MSCT, the occlusion length was 25.5mm16.5 (33.119.8 on angiography). Calcifications were evaluated as minimal in 42% (26% angio), moderate in 42% (54%) and severe in 1% (12%) of the cases. No calcification was found in 15% (8%). A possible coronary route was identified in 68% (18% on angio), the lumen was relatively visible in 77%, acceptable in 23% and eccentric in 98%. One side branch was observed in 62 %, two in 8% and none in 30% of the CTO. Procedural difficulty was assessed by angio using a scale of 1 (very easy) to 5 (extremely difficult) with a mean rate of 3.540.92 falling to 2.620.81 after reading the MSCT data. MSCT was deemed as extremely useful in 80%, useful in 18% and non useful in 2%. Overall procedural success was achieved in 79% of the CTOs. Conclusion . MSCT appears to be a new tool for optimising procedural strategy and increasing success rate in CTO angioplasty.

We investigated the overall success rate of percutaneous coronary intervention (PCI) as a treatment for coronary chronic total occlusion and sought to determine the predictive factors of technical success and of one-year major adverse cardiac events (MACE). These factors have not been conclusively defined. Using data from our single-center PCI registry, we enrolled 269 consecutive patients (mean age, 56.13 ± 10.72 yr; 66.2% men) who underwent first-time PCI for chronic total occlusion (duration, ≥3 mo) from March 2006 through September 2010. We divided them into 2 groups: procedural success and procedural failure. We compared occurrences of in-hospital sequelae and one-year MACE between the groups, using multivariate models to determine predictors of technical failure and one-year clinical outcome. Successful revascularization was achieved in 221 patients (82.2%). One-year MACE occurred in 13 patients (4.8%), with a predominance of target-vessel revascularization (3.7%). The prevalence of MACE was significantly lower in the procedural-success group (1.8% vs 18.8%; P <0.001). In the multivariate model, technical failure was the only predictor of one-year MACE. The predictors of failed procedures were lesion location, multivessel disease, the occurrence of dissection, a Thrombolysis In Myocardial Infarction flow grade of 0 before PCI, the absence of tapered-stump arterial structure, and an increase in serum creatinine level or lesion length. In our retrospective, observational study, PCI was successful in a high percentage of chronic total occlusion patients and had a low prevalence of complications. This suggests its safety and effectiveness as a therapeutic option.
