C oronary artery bypass graft (CABG) surgery has been the standard of care for coronary revascularization. However, during long-term follow-up after initial CABG surgery, patients are at risk of subsequent ischemia because of late graft failures and degeneration of native coronary arteries.2 Regarding repeat coronary revascularization in previous CABG surgery cases, in particular for late failure of saphenous vein grafts, the number of patients referred for percutaneous coronary intervention (PCI) has been increasing. 2,3However, in patients with previous CABG surgery, the optimal revascularization strategy and risk stratification are not yet fully known. 4,5Background-The efficacy and prognosis of percutaneous coronary intervention (PCI) as secondary revascularization in patients with previous coronary artery bypass graft surgery remain uncertain. Methods and Results-We retrospectively evaluated 434 consecutive patients with previous coronary artery bypass graft surgery hospitalized for PCI between 2004 and 2011 (men 84%, age 71 (interquartile range, 66-76) years) and calculated the coronary artery bypass graft Synergy Between Percutaneous Coronary Intervention With Taxus score (CSS) before (baseline CSS) and after PCI (post-PCI CSS). Patients were divided into 2 groups based on median post-PCI CSS: low-score (≤23; n=217) and high-score groups (>23; n=217). Major adverse cardiovascular events (MACE) were defined as the composite of cardiovascular death, myocardial infarction, and unplanned repeat revascularization for myocardial ischemia. The median baseline and post-PCI CSS were 30 (interquartile range, 21-40) and 23 (interquartile range, 14.5-33.5), respectively. During a median follow-up of 69 months, the prevalence of MACE and cardiac death differed significantly between the 2 post-PCI CSS groups (MACE: low, 13.8%; high, 28.6%; P<0.001; cardiac death: low, 6.2%; high, 16.7%; P=0.002). In multivariable analysis, the high post-PCI CSS divided by the median was associated with substantially greater cumulative MACE (hazard ratio, 2.09; 95% confidence interval, 1.31-3.34; P=0.002) and cardiac death (hazard ratio, 2.02; 95% confidence interval, 1.03-3.98; P=0.042) compared with the low post-PCI CSS. Net reclassification improvement analysis revealed that post-PCI CSS resulted in significantly improved prediction of MACE and cardiac death compared with baseline CSS. Conclusions-In this external validation study, the CSS was a potential prognostic factor after subsequent PCI, even for previous coronary artery bypass graft surgery patients.

Esophageal hiatus hernia has been known to cause symptoms of congestive heart failure or syncope after meal due to compression of the heart, mainly the left atrium. However, compression of the left ventricle resulting in syncope has never been reported. Seventy-one year old woman developed syncope after taking a lunch. A chest roentgenogram showed possible mass lesion behind the heart. An echocardiogram revealed a mass lesion posterior to the left ventricle, resulting in "banana-shaped" deformity. A CT scan revealed a giant esophageal hiatus hernia which compressed the left ventricle. Cardiac catheterization revealed marked pressure gradient in the left ventricle suggestive of intracavitary obstruction after isoproterenol infusion. Left ventricular compression due to enlarged giant hiatus hernia after meal resulted in intracavitary obstruction of the left ventricle, causing syncopal episode in this particular patient. Dehydration and diastolic dysfunction may also have contributed.
