Recently, a renewed interest has developed for facilitated mechanical anastomotic devices especially for minimal invasive techniques or limited access surgery. The initial experience with the first successful creation of mechanical vein-to-coronary artery anastomoses in humans is reported. Methods and ResultsBetween November 2000 and June 2001, 14 patients scheduled for multivessel coronary artery bypass grafting (CABG) procedure were investigated. One vein graft-to-coronary artery anastomosis per patient was performed with the St. Jude Medical ATG Symmetry coronary connector system (stainless steel investigational device, not yet commercially available). We evaluated the overall performance of the device. Intraoperative flow measurements of the grafts using transit time methods were measured. A postoperative angiographic control was performed immediately after the procedure in all patients. Hemostasis was instantaneous in all cases and all anastomoses (mechanical n=14, sutured n=40) were patent. Mean intraoperative flow measurements for the mechanical anastomosed vein grafts was 75±25 mL/min. Three month angiogram or MRI angiography is available to date in 11 patients. Ten connector grafts were patent and 1 was occluded. There were no cardiac-related adverse events or return of angina; exercise tolerance tests and stress electrocardiograms were normal in all patients. ConclusionsThe St. Jude Medical ATG Symmetry coronary connector system is a new device for sutureless distal vein graft-to-coronary artery anastomoses in CABG. This system allows the construction of geometrically perfect anastomoses. This technology represents a further step in a new era of sutureless anastomoses in cardiac surgery.","PeriodicalId":10194,"journal":{"name":"Circulation: Journal of the American Heart Association","volume":"20 1","pages":"I-1-I-4"},"PeriodicalIF":0.0,"publicationDate":"2002-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73843082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of our study was to determine whether MyoD could induce primary cardiac fibroblasts, isolated from infarcted myocardium or pericardium, to undergo myogenic conversion in a clinically relevant approach. Methods and ResultsPrimary rat fibroblasts from 7-day-old infarcted myocardium or normal pericardium were transfected by an E1/E3-deleted adenoviral vector carrying both a human MyoD cDNA driven by a CMV promoter and a green fluorescent protein (GFP) reporter gene driven by a second CMV promoter. Expression of MyoD caused myogenic differentiation of cultured fibroblasts, as defined by elongation and fusion into multinucleated myotubes, typical cross striation as identified by electron microscopy, and positive immunostaining for sarcomeric actin, fast myosin heavy chain (MHC), and actinin. The myogenic cells (1.5×106) were transplanted into the infarcted myocardium 7 days after coronary artery occlusion. By 1 month after transplantation, the converted fibroblasts gave rise to a cluster of myogenic cells that in a few hearts occupied a large part of the scar with positive immunostaining for the myogenic proteins fast-MHC and sarcomeric actin. A few cells expressed the gap junction protein connexin 43 in a disorganized manner. There was no positive staining in the control hearts treated with injections of untreated fibroblasts or culture medium. ConclusionsOur work shows that it is possible to exploit the unique capacity of MyoD to activate myogenesis in fibroblasts ex vivo and to create a vast source of autologous myogenic cells for transplantation.","PeriodicalId":10194,"journal":{"name":"Circulation: Journal of the American Heart Association","volume":"PP 1","pages":"I-125-I-130"},"PeriodicalIF":0.0,"publicationDate":"2002-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84545946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a last several years, cryoablation was substituted for atrial incision in many reports to simplify the maze procedure. However, there has been no comparative study to delineate the feasibility of the use of cryoablation. Methods and ResultsWe compared the early and intermediate-term results of the maze procedure including pulmonary venous isolation from the left atrium using cryoablation (CM) with our conventional (Kosakai) maze procedure (KM) including encircling incision around the orifices of pulmonary veins. One hundred and 10 pairs of patients were matched in the age, left atrial dimension >70 mm, duration of AF >0 years, previous cardiac surgery, mechanical valve implantation and concomitant aortic valve procedures. CM required significantly shorter cardiopulmonary bypass time (186±56 minute versus 214±47 minute, P =0.001) and aortic cross-clamp time (134±43 minute versus 144±37 minute, P =0.03) than KM with less chest tube drainage (590±353 mL versus 745±618 mL, P =0.02) for 12 hours after operation. The sinus rhythm restoration rate in CM group (85.4%) was comparable with KM group (86.4%) at discharge. In the late results, the actuarial freedom from recurrence of sustained AF at 3 years in CM group (97.7%) was not significantly (P =0.11) different from that in KM group (90.4%). The actuarial freedom from stroke at 3 years in CM group was 99.0%. ConclusionThe modification of the maze procedure including cryoablation for pulmonary venous isolation provided less aortic cross-clamp time and less amount of chest tube drainage with the comparable recovery and maintenance of sinus rhythm with KM. CM is a reliable and less invasive surgical option for the AF associated with mitral valve disease.","PeriodicalId":10194,"journal":{"name":"Circulation: Journal of the American Heart Association","volume":"23 1","pages":"I-46-I-50"},"PeriodicalIF":0.0,"publicationDate":"2002-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88423932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Segments with intact perfusion without contractile reserve are frequently observed inpatients with ischemic cardiomyopathy. The clinical relevance of this observation is unclear; in particular, the functional outcome after revascularization is unknown. Thus, contractile reserve (using low-dose dobutamine echocardiography) and perfusion (using resting 99mTc tetrofosmin) were evaluated in 114 patients with ischemic cardiomyopathy and the findings were related to functional outcome (9 to 12 months after revascularization). Methods and ResultsPatients (n=114) with ischemic cardiomyopathy undergoing surgical revascularization were evaluated for perfusion (using 99mTc tetrofosmin) and contractile reserve (using low-dose dobutamine echocardiography). Contractile function (two-dimensional echocardiography) was assessed before and 9 to 12 months after revascularization. In the 1 336 dysfunctional segments, perfusion was preserved in 51% of the segments and contractile reserve in 31% (P <.05); 47% of the segments with perfusion did not exhibit contractile reserve. The majority (66%) of segments with recovery of function postrevascularization had intact perfusion and contractile reserve; the majority (58%) of segments without functional recovery lacked both perfusion and contractile reserve. Interestingly, 22% of segments with functional recovery and 25% of segments without functional recovery showed intact perfusion without contractile reserve. ConclusionSegments with intact perfusion/contractile reserve have a high likelihood of recovery of function postrevascularization; segments without contractile reserve/perfusion have a low likelihood of recovery and segments with intact perfusion without contractile reserve have an intermediate likelihood of recovery.","PeriodicalId":10194,"journal":{"name":"Circulation: Journal of the American Heart Association","volume":"95 1","pages":"I-14-I-18"},"PeriodicalIF":0.0,"publicationDate":"2002-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83349894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We performed TSGPs to seal the primary entry site to treat and prevent complications of aortic dissection. The early to mid-term outcomes were analyzed.Methodsand Results—Thirty-seven patients with a primary intimal tear in descending aorta underwent TSPG. TSGP was performed in 16 acute onset dissections (AOD) with dissection-related complications instead of emergency surgery. Eight AOD without complications were treated to prevent aneurysmal enlargement. Thirteen chronic dissections were treated to prevent rupture. TSGP was technically successful in all cases. One patient with prehospital rupture died. The hospital mortality rate was of 2.7% overall, 6.3% in AOD with complications, 0% in AOD without complications and in chronic dissections. One persistent endoleak required open surgery, and 1 intimal tear was caused by the stent-graft, necessitating an additional TSGP. The primary success rate was 94.4% overall. After hospital discharge, no patient died or suffered aortic rupture during an average follow-up of 24.5 months. New intimal tears caused by the stent-grafts and a secondary endoleak developed in 3 AOD patients. One open procedure and 2 additional TSGPs were performed. Actuarial survival rate and cardiovascular event-free rate at 2 years are 97.3% and 78.3% overall, 93.8% and 48.0% in AOD with complications, 100% and 87.5% in AOD without complications, and both 100% in chronic dissections.

Methods and ResultsA moderate-sized LV aneurysm was created by proximal ligation of the left coronary artery in 47 Lewis rats. Four weeks later, they were underwent another operation and received culture medium injection (n=10; group I), fetal CM-TX (n=10; group II), purse-string LV repair with culture medium injection (n=14; group III), or LV repair with fetal CM-TX (n=13; group IV).

However, because a significant number of patients presenting with ACS may be sent directly to open heart surgery while still on anticoagulation, it is important to understand any potential bleeding risks that may be associated with the use of enoxaparin under these circumstances. MethodsFrom 1998 to 2001, 1159 consecutive patients presenting with an acute coronary syndrome who received either UFH (n=1008) or enoxaparin (n=151) before proceeding to open heart surgery for urgent therapy during the same hospitalization were included in this study. Incidence of perioperative bleeding as evidenced by the units of blood products (packed red blood cells or platelets) transfused or the need for surgical re-exploration for postoperative bleeding was recorded. ResultsAverage age was 65±11 and 67±11 years for patients receiving UFH and enoxaparin, respectively (P= 0.005). Seventy-five percent of those receiving UFH and 64% of those receiving enoxaparin (P <0.005) were males. After discharge, the incidence of rehospitalization for hemorrhage requiring return to surgery for re-exploration was 7.9% in the enoxaparin group and 3.7% in the UFH group (adjusted hazard ratio=2.6, P =0.03). The use of blood products did not differ between groups (UFH=2.7±6.5 U and enoxaparin=2.3±4.5 U;P =NS). ConclusionThe preoperative use of enoxaparin compared with UFH in patients presenting with an ACS who undergo open-heart surgery during the same hospitalization is associated with a significantly increased incidence of re-exploration for postoperative bleeding.
