Preserved autoregulation of coronary flow after off-pump coronary artery bypass grafting: retrospective assessment of intraoperative transit time flowmetry with and without intra-aortic balloon counterpulsation

Background Intra-aortic balloon pumping (IABP) markedly increases graft flow after coronary artery bypass grafting (CABG) with cardiopulmonary bypass. We sought to delineate the effects of IABP on graft flow after off-pump CABG (OPCAB). Methods The clinical records of 32 patients (25 male, 7 female; mean age: 70 ± 9 years) who underwent OPCAB with IABP between January 2011 and May ...

Prediction of 1-year clinical outcomes using the SYNTAX score in patients with prior heart failure undergoing percutaneous coronary intervention: sub-analysis of the SHINANO registry

Although coronary artery disease (CAD) is common in patients with heart failure (HF), little is known about the prognostic significance of coronary lesion complexity in patients with prior HF undergoing percutaneous coronary intervention (PCI). The aim of this study was to investigate whether the coronary Synergy between Percutaneous Coronary Intervention with TAXus and Cardiac ...

Predictors and prevention of flow insufficiency due to limited flow demand

Background We investigated the impacts of flow demand and native coronary stenosis on graft flow and patency. Methods We reviewed the angiograms of 549 bypass grafts in 301 patients who underwent off-pump coronary artery bypass grafting since 2007. Grafts consisted of 237 internal thoracic artery to left anterior descending artery; 97 internal thoracic artery and 52 saphenous vein ...

Candidal mediastinitis successfully treated using vacuum-assisted closure following open-heart surgery

Deep sternal wound infections (DSWIs) are an uncommon but serious complication after open-heart surgery. The reported incidence of DSWIs due to Candida albicans is 0.4%, but these infections have an extremely high mortality of 56%. We herein report a rare case of a 79-year old woman who suffered from Candidal DSWI after repeated open-heart surgeries. We treated her with negative ...

Identification of Inter-Organ Vascular Network: Vessels Bridging between Organs

Development and homeostasis of organs and whole body is critically dependent on the circulatory system. In particular, the circulatory system, the railways shuttling oxygen and nutrients among various organs, is indispensible for inter-organ humoral communication. Since the modern view of the anatomy and mechanics of the circulatory system was established in 17th century, it has ...

Systemic hyperkalemia and mild hypothermia for valve surgery in patients with patent internal mammary artery graft

Myocardial protection is compromised in patients with a patent internal mammary artery (IMA) graft. We assessed the advantages of systemic hyperkalemia with mild hypothermia for valve surgery in patients with a patent IMA graft. Nine patients (mean age 71.5±7.0 years) with a patent IMA graft underwent valve surgery from May 2004 to July 2009. Of those, eight underwent aortic valve ...

Determinants for successful sequential radial artery grafting to the left circumflex and right coronary arteries

The aim of this retrospective observational study was to delineate determinants for antegrade flow and entire patency of the sequential radial artery graft (RAG) in the left circumflex artery (LCX) and right coronary artery (RCA). Angiograms of 432 RAGs, which were sequentially anastomosed to the LCX and RCA, and were proximally anastomosed with the in-situ internal thoracic artery ...

A primary angiosarcoma in the aorta

A 60-year-old woman after aortic valve replacement had an acute abdominal pain. Computed tomography demonstrated a tumor in the aorta, which originated from the distal portion of the thoracic aorta and extended to the aortic bifurcation. At autopsy, the orifices of celiac, superior and inferior mesenteric, right and left renal arteries were consistently occluded by incursion of the ...

Genetic manipulation and quantitative‐trait loci mapping for nitrogen recycling in rice

Immunocytological studies in this laboratory have suggested that NADH‐dependent glutamate synthase (NADH‐GOGAT; EC 1.4.1.14) in developing organs of rice (Oryza sativa L. cv. Sasanishiki) is involved in the utilization of glutamine remobilized from senescing organs through the phloem. Because most of the indica cultivars contained less NADH‐GOGAT in their sink organs than japonica ...
