TL;DR: It was concluded that intraoperative coronary angiography using fluorescein rapidly provided essential information for the real-time evaluation of CABG surgery without any side effects.
Abstract: To improve the safety and reliability of coronary artery bypass grafting (CABG), intraoperative coronary angiography using fluorescein was investi gated both experimentally and clinically.Results. In experiments using mongrel dogs, the optimal procedures were determined to be as follows.1. Complete all distal anastomoses.2. Under the illumination of a 6-watt black light hung 10 cm above the heart, 0.06% fluorescein (0.5 mg/kg BW) is injected as a bolus from the proximal end of the graft. Histologically the direct injection of fluorescein into the coronary artery was shown to cause no injury to the vascular wall.In clinical application, the distribution of the graft flow, the area perfused through the graft, and the patency of the anastomoses were well evaluated in real time by observing the fluorescence. Unexpected narrowing of the anasto mosis and the maldistribution of graft flow were detected in 2 patients by this examination during cardioplegic arrest, and the necessity for additional graft ing, as we...

TL;DR: A new entity "ASD, MR complex" is proposed for this combined lesion, as it demonstrates a specific pathophysiology, and necessitates a different procedure for surgical correction from that of a secundum atrial septal defect without other anomalies.
Abstract: Non-rheumatic mitral regurgitation was found in 9.1% (27 patients) of all patients with secundum atrial septal defect (298 patients) who were operated on during a 13-year period at the Mitsui Memorial Hospital. This combined lesion was more frequent in female (12.3%, 19 patients) than male (5.6%, 8 patients), and the incidence tended to increase with age. Inspection at operation revealed a marked fibrous thickening of the anterior and posterior mitral valve leaflets with a localized bulging into the left atrium in the posteromedial commissural area. Similar, but less prominent change was found in nearly all patients above 20 years of age with mitral regurgitation, although the small area where the commissural chordae were attached was not involved. A friction between anterior and posterior mitral leaflets due to abnormal left ventricular motion secondary to the right ventricular volume overload might be responsible to the genesis of this lesion. Mitral annuloplasty was performed on 21 of 27 patients with a satisfactory result without operative mortality. Except one case of early death from cerebral thromboembolism they were all restored to a functional status of class I by NYHA standard within one year after operation, and there were no late death during a follow-up period of as long as 12 years. We propose a new entity "ASD, MR complex" for this combined lesion, as it demonstrates a specific pathophysiology, and necessitates a different procedure for surgical correction from that of a secundum atrial septal defect without other anomalies.

TL;DR: An extracardiac pumping for supplementing the circulation of blood, including the cardiac output, in a patient without any component thereof being connected to the patient's heart, and methods of using same as mentioned in this paper.
Abstract: An extracardiac pumping for supplementing the circulation of blood, including the cardiac output, in a patient without any component thereof being connected to the patient's heart, and methods of using same. One embodiment provides a vascular graft that has a first end that is sized and configured to couple to a non-primary blood vessel and a second end that is fluidly coupled to a pump to conduct blood between the pump and the non-primary blood vessel. An outflow conduit is also provided that has a first end sized and configured to be positioned within the same or different blood vessel, whether primary or non-primary, through the vascular graft. The outflow conduit is fluidly coupled to the pump to conduct blood between the pump and the patient. The vascular graft may be connected to the blood vessel subcutaneously to permit application of the extracardiac pumping system in a minimally-invasive procedure.

TL;DR: The data suggest that use of the RA and the IEA in composite conduits for myocardial revascularization is feasible and can be safely used when bilateral internal mammary artery or sequential internal mammARY artery grafting is not advisable.
