A Case of Thrombectomy for Loeffler's Endocarditis.

Loeffler's endocarditis, characterized by eosinophilic infiltration leading to thrombus formation and fibrosis in the ventricle, is associated with severe complications, such as embolism and heart failure. While anticoagulation and steroids are standard treatments, surgical thrombectomy is rarely reported. This is a case report of a 74-year-old man presented with an abnormal electrocardiogram. Echocardiography revealed a 38 × 29 mm mass in the left ventricular apex, and blood studies revealed hypereosinophilia, leading to a diagnosis of Loeffler's endocarditis. Despite warfarin treatment, the thrombus persisted. The left ventricular intracardiac thrombus exhibited significant mobility, and we decided to perform a thrombectomy via a trans-left ventricular approach. After the surgery, steroid therapy was initiated. The patient recovered without recurrence of the thrombus or deterioration in cardiac function. Left ventricular thrombectomy for Loeffler's endocarditis is considered a beneficial option to prevent thrombosis.

Effects of peripheral artery disease on long-term outcomes after percutaneous coronary intervention versus coronary artery bypass grafting in patients with severe coronary artery disease.

BACKGROUND: There is a scarcity of data evaluating the effect of peripheral artery disease (PAD) on long-term mortality after percutaneous coronary intervention (PCI) relative to coronary artery bypass grafting (CABG) in patients with severe coronary artery disease in real-world practice. METHODS: Among 14,867 consecutive patients who underwent their first coronary revascularization with PCI or isolated CABG between 2011 and 2013 in the CREDO-Kyoto PCI/CABG registry Cohort-3, the current study population consisted of 3380 patients with three-vessel coronary artery disease or left main coronary artery disease. Long-term clinical outcomes were compared between PCI and CABG stratified by the presence or absence of PAD. Median clinical follow-up was 5.9 (IQR: 5.1-6.8) years. RESULTS: There were 461 patients with PAD (PCI: N = 307, CABG: N = 154), and 2919 patients without PAD (PCI: N = 1823, CABG: N = 1096). The cumulative 5-year mortality after coronary revascularization was 31.2 % in patients with PAD and 16.2 % in those without PAD (p < 0.0001). There was a higher risk of PCI relative to CABG for all-cause death in patients with and without PAD (adjusted HR, 1.59; 95%CI, 0.99-2.53; p = 0.054, and HR, 1.25; 95%CI, 1.01-1.56; p = 0.04) without interaction (p interaction p = 0.48); Nevertheless, there was no excess risk of PCI relative to CABG for cardiovascular death regardless of PAD. CONCLUSIONS: The long-term mortality after coronary revascularization was significantly higher in severe CAD patients with PAD than those without PAD. There was a higher mortality risk of PCI relative to CABG in patients with and without PAD without interaction, which was mainly driven by excess non-cardiovascular deaths.

Early and Midterm Outcomes of "No-Touch" Saphenous Vein Grafts in Japanese Institutions

ABSTRACT Introduction: There have been several attempts to overcome the poor graft patency of saphenous vein grafts. "No-touch" saphenous vein graft (NT-SVG) could be a solution to improve graft patency. We aimed to investigate the early and midterm outcomes of coronary artery bypass grafting (CABG) using NT-SVGs in our hospitals. Methods: This is a retrospective study of 105 patients who underwent CABG using 130 NT-SVGs between August 2013 and December 2021. NT-SVGs were harvested with about a 5-mm margin of surrounding tissue on both sides of the vein with minimal manipulation. Then, the NT-SVG was dilated by natural arterial pressure without manual distension. After surgery, most of NT-SVGs were assessed by cardiac catheterization or multidetector computed tomography (MDCT) to determine early graft patency. Late graft assessments by MDCT were performed about every five years after surgery. Results: The early graft patency of NT-SVGs was 100% (125/125); however, two cases of graft twisting were found. Both cases spontaneously resolved. Leg wound infections of NT-SVG harvesting site were seen in 6.2% of patients. Peripheral neuropathy of the legs such as skin numbness and tingling were frequently observed, which lasted up to one year, but no more than two years after surgery. The midterm graft patency of NT-SVGs was excellent (five-year patency of NT-SVGs was 95.8%). Conclusion: The early and midterm graft patency of NT-SVGs was satisfactory. Although leg wound complications can be seen on the harvesting NT-SVG site, the "no-touch" harvesting technique of SVG could improve graft patency and clinical outcomes of CABG.
