Karsan RB, Allen R, Powell A, Beattie GW. Minimally-invasive cardiac surgery: a bibliometric analysis of impact and force to identify key and facilitating advanced training. J Cardiothorac Surg 2022; 17:236. [PMID: 36114506 PMCID: PMC9479391 DOI: 10.1186/s13019-022-01988-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Accepted: 08/30/2022] [Indexed: 11/28/2022] Open
Abstract
Background The number of citations an article receives is a marker of its scientific influence within a particular specialty. This bibliometric analysis intended to recognise the top 100 cited articles in minimally-invasive cardiac surgery, to determine the fundamental subject areas that have borne considerable influence upon clinical practice and academic knowledge whilst also considering bibliometric scope. This is increasingly relevant in a continually advancing specialty and one where minimally-invasive cardiac procedures have the potential for huge benefits to patient outcomes.
Methods The Web of Science (Clarivate Analytics) data citation index database was searched with the following terms: [Minimal* AND Invasive* AND Card* AND Surg*]. Results were limited to full text English language manuscripts and ranked by citation number. Further analysis of the top 100 cited articles was carried out according to subject, author, publication year, journal, institution and country of origin. Results A total of 4716 eligible manuscripts were retrieved. Of the top 100 papers, the median (range) citation number was 101 (51–414). The most cited paper by Lichtenstein et al. (Circulation 114(6):591–596, 2006) published in Circulation with 414 citations focused on transapical transcatheter aortic valve implantation as a viable alternative to aortic valve replacement with cardiopulmonary bypass in selected patients with aortic stenosis. The Annals of Thoracic Surgery published the most papers and received the most citations (n = 35; 3036 citations). The United States of America had the most publications and citations (n = 52; 5303 citations), followed by Germany (n = 27; 2598 citations). Harvard Medical School, Boston, Massachusetts, published the most papers of all institutions. Minimally-invasive cardiac surgery pertaining to valve surgery (n = 42) and coronary artery bypass surgery (n = 30) were the two most frequent topics by a large margin. Conclusions This work establishes a comprehensive and informative analysis of the most influential publications in minimally-invasive cardiac surgery and outlines what constitutes a citable article. Undertaking a quantitative evaluation of the top 100 papers aids in recognising the contributions of key authors and institutions as well as guiding future efforts in this field to continually improve the quality of care offered to complex cardiac patients.

Abstract
AIM Acute aortic dissection (AAD) has been considered a contraindication for extracorporeal cardiopulmonary resuscitation (ECPR). However, studies are lacking regarding the epidemiology and effectiveness of ECPR for AAD. We aimed to examine whether ECPR for AAD during refractory cardiac arrest is effective. METHODS Using the Japanese Diagnosis Procedure Combination inpatient database from July 2010 to March 2018, we identified all emergently hospitalized adults who received ECPR on the day of admission and all AAD patients who received cardiopulmonary resuscitation on the day of admission. ECPR was defined as receiving both cardiopulmonary resuscitation and percutaneous extracorporeal membrane oxygenation. Outcomes were in-hospital mortality and neurological outcomes. We calculated the incremental cost-effectiveness ratio of ECPR for AAD. RESULTS We identified 398 AAD patients with ECPR, 9840 non-AAD patients with ECPR, and 9709 AAD patients with cardiopulmonary resuscitation but not ECPR. The incidence of AAD among the patients with ECPR on the day of admission was 3.9%. In-hospital mortality was 98% in AAD patients with ECPR, 79% in non-AAD patients with ECPR, and 98% in AAD patients with cardiopulmonary resuscitation but not ECPR. Seven AAD patients survived to discharge after ECPR; of these, six patients had good neurological outcomes at discharge. The incremental cost-effectiveness ratio of ECPR for AAD was estimated at 161,504 US dollars per quality-adjusted life year gained. CONCLUSION ECPR successfully improved outcomes and/or facilitated surgery for a small number of AAD patients with refractory cardiac arrest; however, the cost burden of ECPR for AAD patients may be unacceptably high.

Abstract
Reoperations on the proximal thoracic aorta are increasingly observed after previous aortic or cardiac operations. Redo proximal aortic surgery remains challenging with an increased mortality compared to first-time operations. For a successful redo proximal aortic surgery in a patient with complex pathological conditions, the surgical procedure and cardiopulmonary bypass (CPB) should be simplified as much as possible. Herein, we report our experience of proximal aortic reoperations in which the strategy consisted of an axillo-axillary (jugular) and a femoro-femoral CPB in combination with minimal dissection of surgical adhesions. Satisfactory full-flow CPB was achieved with peripheral cannulations and the aid of vacuum-assisted venous drainage. A suitable surgical view of the proximal aorta was obtained without dissection of the heart. There was no operative mortality and the peripheral CPB was well managed without technical problems. We consider that the proposed strategy makes proximal aortic reoperations safe and simple.

Abstract
The axillary artery is an established alternative cannulation site for peripheral cardiopulmonary bypass (CPB). However, axillary vein cannulation is not as common. Here, we present our experience with an axillo-axillary CPB combined with a femoro-femoral CPB in redo aortic root replacement. The full-flow bypass was obtained with vacuum-assisted drainage and excellent decompression of the heart was achieved without left heart venting. Although only adhesions around the aortic root graft were dissected, a comfortable surgical field could be obtained with our CPB strategy. Axillary vessels were easy to expose with a small single skin incision. Cerebral protection could be achieved in both antegrade and retrograde fashion when the circulatory arrest was required for an additional arch procedure. Our strategy based on axillo-axillary and femoro-femoral CPB was effective and feasible in redo aortic root replacement. We consider that it simplified the complex aortic reoperation.

Abstract
OBJECTIVE This retrospective study aimed to evaluate the results of our experience with axillary artery cannulation via a side graft in aortic valve replacement in patients with ascending aortic atherosclerotic disease. METHODS From January 2002 to 2012, we operated on 76 patients for aortic valve disease with the use of the axillary artery for arterial inflow in our institute. The indications for cannulation of the axillary artery were aortic aneurysm in 37 patients, severe aortic atherosclerosis in 28 patients, and re do surgery in 11 patients. RESULTS Right axillary artery cannulation via a side graft provides sufficient antegrade aortic flow of 2.6 ± 0.1 L/m(2) during cardiopulmonary bypass. No additional arterial cannulation was necessary to obtain sufficient perfusion during cardiopulmonary bypass. Although permanent perioperative stroke was observed in two patients, this did not occur during the operation. There were no problems with cannulation or wound and graft infections. During the follow-up period, there were no thrombotic events due to an axillary graft stump in the right upper extremities. CONCLUSIONS Axillary artery cannulation via a side graft is a useful and safe option for cardiopulmonary bypass in patients with atherosclerotic disease of the ascending aorta undergoing aortic valve replacement.

Abstract
OBJECTIVES The aim of the study was to investigate the usefulness of transapical cannulation as the routine cannulation site in patients with acute aortic dissection and to compare it with other cannulation methods. METHODS Between January 2010 and December 2013, emergency surgery was performed in 111 consecutive patients with acute type A aortic dissection. Patients were divided into two groups: transapical cannulation group and other cannulation sites group (including femoral and axillary artery cannulation). Pre-, intra- and postoperative data were compared between these two groups of patients. RESULTS Transapical cannulation was the most frequent cannulation site (78 patients, 70.3%), the femoral artery was selected in 24 patients (21.6%) and the axillary artery in 9 patients (8.1%). The mortality rate in the transapical group was 16.7% and 18.2% when other cannulation sites were chosen (p=0.85). No difference in postoperative stroke rate (6.4% vs 9.1%, p=0.62, transapical vs other cannulation sites group, respectively), myocardial infarction (6.4% vs 6.1%, p=0.94) and postoperative acute renal insufficiency incidence (9% vs 6.1%, p=0.61) was found. CONCLUSIONS Routine transapical cannulation in patients with acute type A aortic dissection is a fast and safe way to establish cardiopulmonary bypass. There is no difference in major operative outcomes after transapical cannulation when compared to the other cannulation sites.

Right axillary arterial perfusion for descending thoracic or thoracoabdominal aortic aneurysm repair with open proximal anastomosis through left thoracotomy. Gen Thorac Cardiovasc Surg 2014; 62:547-52.

Abstract
BACKGROUND We examined the effectiveness of right axillary arterial perfusion through an interposed Dacron graft in the prevention of cerebral embolism or complications related to ascending aortic cannulation in open proximal anastomosis technique of descending thoracic aortic aneurysm (TAA) or thoracoabdominal aortic aneurysm (TAAA) repair under deep hypothermic circulatory arrest through left thoracotomy. METHODS Between May 2000 and August 2012, 44 patients underwent TAA or TAAA repair using open proximal technique under DHCA. These patients were divided into two groups for evaluation of the effectiveness of right axillary arterial perfusion. Group A included patients who underwent TAA or TAAA repair with ascending aortic cannulation (n=15). Group B was composed of patients who had TAA or TAAA repair with right axillary arterial perfusion through the interposed Dacron graft (n=29). RESULTS Mortality in this series was 4.5% (2 of 44 patients; 1 in each group); wherein, the causes were sepsis due to graft infection and aortic dissection (Stanford type A). The incidence rates of cerebral embolism were 27 % (4 of 15 patients in group A) and 3.4% (1 of 29 patients in group B) (p=0.0392, Fisher's exact test). The rates of complications in relation to the aortic cannulation site (dissection or bleeding) were 13% (2 of 15 patients in group A) and 0% (0 of 25 patients in group B). CONCLUSIONS Right axillary perfusion facilitates easy evacuation of air and allows prompt recommencement of upper body circulation. Consequently, it minimizes the risk of cerebral embolism or complications in relation to aortic cannulation through left thoracotomy.

Abstract
The use of extracorporeal membrane oxygenation (ECMO) is becoming a popular tool in the treatment of cardiogenic shock. We present two case reports where classical veno-arterial peripherally cannulated ECMO therapy proved insufficient with profuse cerebral hypoxemia. After augmenting the setting into veno-veno-arterial ECMO, we achieved a remarkable improvement of all oxygenation parameters. The simultaneous use of veno-venous and veno-arterial ECMO might display as a novel strategy to counteract the coronary and cerebral hypoxemia in veno-arterial ECMO therapy in patients with therapy-refractory cardiogenic shock or in combined cardiopulmonary failure. In this manuscript, the veno-veno-arterial ECMO setup is described in full detail and different venous cannulas are discussed.

Abstract
BACKGROUND Total axilloaxillary cardiopulmonary bypass (CPB) is an alternative peripheral cannulation technique that has the advantages of antegrade flow during CPB, monohemispherical brain perfusion in case of circulatory arrest, and achieving excellent decompression of the heart during sternotomy. The results of this strategy, particularly beyond the immediately postoperative period, are not well known. METHODS Eleven patients with huge aortic aneurysms (>80 mm) and/or acute-subacute ascending aorta dissections underwent surgery with totally axilloaxillary CPB. Short- and midterm outcomes, including survival and complications relating to axilloaxillary cannulation, were reported. RESULTS All attempts at axillary artery cannulation were successful. Ten of the 11 axillary vein cannulation attempts were successful, and the target pump flow was achieved via the axillary vein alone. Postoperatively, clinical examinations revealed no cases of arm ischemia or compartment syndrome. Three patients (27.3%) experienced ipsilateral brachial plexus neuropathy that produced right hand weakness. The neuropathy was transient in 2 patients, and the symptoms resolved completely. Hospital death occurred in 1 (9.1%) of the 11 patients. The mean (±SD) follow-up time was 956 ± 292 days. One of the survivors died on postoperative day 105 from subacute graft infection and sepsis. The right arms of all 9 of the living patients were examined physically and by Doppler ultrasonography. We found a chronic recanalized thrombotic change in the subclavian vein in 1 patient (11.1%), who had no complaints. CONCLUSIONS Axilloaxillary CPB is an alternative technique that can be used under certain conditions. Adding axillary venous cannulation to axillary artery cannulation at least does not increase the risk of a procedure that uses the axillary artery alone, either in the early or mid term.

Abstract
In the presence of multiple concomitant occlusive and aneurysmal diseases, selection of the brain protection method is a primary concern. A case with a disease triad of stenotic lesions in internal carotid arteries, coronary artery atherosclerosis, and an ascending-arcus aorta aneurysm is presented. We simultaneously performed right carotid endarterectomy, coronary artery bypass grafting, and graft replacement of the ascending-arcus aorta. Brain protection was achieved with continuous right brachial artery antegrade selective cerebral perfusion under moderate hypothermia, following carotid endarterectomy. The operative technique is detailed and antegrade selective cerebral perfusion following the carotid endarterectomy for aneurysmal surgery is discussed.

Abstract
BACKGROUND The impact of axillary artery cannulation (AXC) on survival and neurologic outcome after operation for ascending aortic disease was retrospectively evaluated. METHODS We reviewed 869 patients with ascending aorta/root repairs (1995 to 2005), principally for atherosclerotic and degenerative aneurysms and chronic and acute type A dissections. Arterial cannulation was through the ascending aorta (AAC) in 157 patients, the femoral artery (FAC) in 261, and the right axillary artery (AXC) in 451. Patients cannulated at different sites were compared for preoperative comorbidities and outcomes (mortality and stroke) for each cause. RESULTS Of the 122 patients with atherosclerotic aneurysms, 66 with right AXC had significantly better outcomes (p = 0.02): 64 of 66 survived vs 24 of 26 with FAC and 27 with 30 of AAC; no strokes occurred (vs 2 of 26 with FAC and 4 of 30 with AAC). No significant advantage for AXC was found with ascending aortic operation in 495 degenerative aneurysms, 106 chronic, or 65 acute type A dissections, 41 patients with endocarditis, or in 18 with aneurysms of other causes; AXC was associated with a significantly better outcome (p = 0.05) in the 869 patients taken together. CONCLUSIONS AXC resulted in superior survival and neurologic outcome in patients with atherosclerotic aneurysms and a marginally better outcome than with cannulation at other sites during proximal aortic procedures for all causes. This study supports AXC in patients with atherosclerotic disease who require complex cardiothoracic operations and in patients requiring proximal aortic intervention regardless of cause.

Abstract
There is a trend towards cannulation of the axillary artery for extracorporeal circulation in patients requiring aortic arch surgery. We analyzed the published data comparing axillary and femoral cannulation for safety and outcome. End points were death; stroke, neurologic, and vascular complications; and malperfusion. Femoral cannulation is safe for extracorporeal circulation in patients without aortic arch surgery. In patients with type A dissections, malperfusion may occur owing to retrograde perfusion of the false lumen and subsequent occlusion of the origin of the supra aortic vessels. Cannulation of the axillary/subclavian artery results in antegrade flow, at least in the right carotid artery, with the possibility of antegrade cerebral perfusion during aortic arch repair. There was a trend towards improved neurologic outcome when the axillary artery was used for extracorporeal circulation in such patients. When different techniques were compared, the use of a side graft for axillary cannulation reduced the complication rate. The lack of randomized trials and the high variety of inclusion criteria in the different studies do not allow a general recommendation for the use of the axillary artery as cannulation site.

Abstract
Devices for venous cannulation have seen significant progress over time: the original, rigid steel cannulas have evolved toward flexible plastic cannulas with wire support that prevents kinking, very thin walled wire wound cannulas allowing for percutaneous application, and all sorts of combinations. In contrast to all these rectilinear venous cannula designs, which present the same cross-sectional area over their entire intravascular path, the smartcanula concept of "collapsed insertion and expansion in situ" is the logical next step for venous access. Automatically adjusting cross-sectional area up to a pre-determined diameter or the vessel lumen provides optimal flow and ease of use for both, insertion and removal. Smartcanula performance was assessed in a small series of patients (76 +/- 17 kg) undergoing redo procedures. The calculated target pump flow (2.4 L/min/m2) was 4.42 +/- 61 L/ min. Mean pump flow achieved during cardiopulmonary bypass was 4.84 +/- 87 L/min or 110% of the target. Reduced atrial chatter, kink resistance in situ, and improved blood drainage despite smaller access orifice size, are the most striking advantages of this new device. The benefits of smart cannulation are obvious in remote cannulation for limited access cardiac surgery, but there are many other cannula applications where space is an issue, and that is where smart cannulation is most effective.

Abstract
Unclampable calcified aorta is an uncommon condition that all cardiac surgeons may encounter and performing aortic valve surgery in this condition with a non cross-clamping technique of using Foley Catheter has rarely been reported. Aortic valve surgery invariably becomes a high-risk, challenging procedure to cardiac surgeon or even a contraindication to surgery when the ascending aorta cannot be clamped due to extensive calcification precluding safe dissection and clamping. We describe and recommend a non cross-clamping technique of using Foley Catheter and report it successful use in two patients who underwent aortic valve replacement with "porcelain" unclampable aorta.

Abstract
Extrathoracic cannulation to establish cardiopulmonary bypass has been widely applied in recent years and includes: (a) repeat surgery, (b) minimally invasive surgery, and (c) cases with diseased vessels such as porcelain, aneurysmal, and dissecting aorta. In addition, the success and relative ease of peripheral cannulation, among other technological advances, has permitted the development of closed chest extracorporeal life support, in the form of cardiopulmonary support and extracorporeal membrane oxygenation. With this development have come applications for cardiopulmonary bypass based support outside the traditional cardiac theatre setting, including emergency circulatory support for patients in cardiogenic shock and respiratory support for patients with severely impaired gas exchange. This review summarises the approach to extrathoracic cannulation for the generalist.

Abstract
The axillary artery may be an alternative cannulation site for patients with diffused atherosclerosis, aortic dissection, and aneurysm. There are different techniques for axillary artery cannulation that can be performed easily with a transcutaneous approach. Small incision necessity, less dissection, and good wound healing are other advantages of this technique.

Abstract
The femoral artery is the usual site of arterial cannulation in thoracic aorta operations through left posterolateral thoracotomy that require cardiopulmonary bypass (CPB) with deep hypothermic circulatory arrest (DHCA). The advantage of this perfusion route is in limiting the duration of circulatory arrest. It is associated, however, with the risk of retrograde embolization or, in cases involving aortic dissection, malperfusion of vital organs. To prevent these risks, we have used the extrathoracic left common carotid artery as the perfusion route. From December 1999 to January 2003, we used cannulation of the left extrathoracic common carotid artery in 42 thoracic aorta operations through posterolateral thoracotomy with an open proximal anastomosis technique during DHCA. The indication for thoracic aortic repair was atherosclerotic ulcer in 7 cases, chronic aortic aneurysm in 18, acute type B dissection in 5, and chronic type B dissection in 12. Cannulation of the extrathoracic left common carotid artery was successful in all patients. Postoperative recovery was uneventful, with no cerebrovascular events in all cases. No cannulation-related complications were observed. One patient died from cardiac insufficiency on postoperative day 5. No peripheral neurological deficits (paraplegia or paraparesis) were observed. Postoperative complications included atrial fibrillation in five patients, reoperation to control hemorrhage in six, respiratory insufficiency in nine, and renal insufficiency in six. These results indicate that cannulation of the left extrathoracic common carotid artery is a useful, reliable method for proximal perfusion during CPB in patients undergoing repair of the descending thoracic aorta through left posterolateral thoracotomy. By providing effective perfusion of the brain, this technique can prolong safe DHCA time. Another advantage is the prevention of cerebral emboli, ensuring retrograde flow to the aortic arch.

Abstract
This presentation summarizes the author's personal observations on the major advances in reoperative cardiac surgery. They include earlier referral for cardiac prosthetic and bioprosthetic cardiac valve dysfunction, alternative incisional approaches to minimize injury to adherent cardiac structures, alternative perfusion sites, improved hemostasis on cardiopulmonary bypass, improved myocardial protection, tailoring the valve prosthesis to the patients' anatomy and clinical situation, "no-touch" technique in reoperative coronary artery surgery, and increasing use of hypothermic circulatory arrest for recurrent ascending arch and descending thoracic pathology. Each of these is explained in detail with the appropriate references and retrospective data collections where appropriate. This risk of reoperative cardiac surgery will continue to improve as these and additional techniques continue to evolve and become simplified. Further investigation into the clinical uses of minimally invasive techniques including robot technology, may eventually reduce morbidity and mortality of reoperations to that equal to primary operations.

Abstract
BACKGROUND Ideal perfusion during ascending aorta-arch surgery should allow easy implementation of antegrade cerebral perfusion while avoiding atheroembolization or false lumen perfusion in dissections. We report favorable experience with direct axillary artery cannulation. METHODS Between 1999 and 2003, 284 patients with a mean age of 62.2 years (25 to 85), underwent axillary artery cannulation using a right angle wire-reinforced catheter. During this interval, attempted axillary cannulation was abandoned in only 14 patients because of inadequate backflow or other complications. Eighty-five patients were female. Severe aortic arteriosclerosis or degeneration was present in 209, aortic dissection in 63, and Marfan disease or aortitis in 12. The Bentall procedure was done in 144 patients, arch replacement in 86, the Yacoub procedure in 18, thoracoabdominal aneurysm repair in 16, and coronary artery bypass grafting in 20. Reoperations were at 30.2%. RESULTS Adverse outcome (hospital death or permanent stroke) occurred in 6.6% (n = 19). Thirteen patients (4.6%) died before hospital discharge, and 13 patients (4.6%; 9 of whom died) suffered permanent stroke. Transient neurologic dysfunction occurred in 9.2% (n = 26). Mean duration of hypothermic circulatory arrest, used in 246 patients, was 26 +/-7 minutes. Mean duration of antegrade cerebral perfusion, used in 139 patients, was 47 +/- 23 minutes. In 93%, the right axillary artery was cannulated. Complications included 2 cases (0.7%) of brachial plexus injury (one transient), and 3 (1%) of localized dissection. CONCLUSIONS Our results suggest that axillary artery cannulation, successful in 95% of patients, may be the optimal technique for reducing perfusion-related morbidity and adverse outcome in operations for acute dissection, atherosclerotic, and degenerative aneurysmal disease. It deserves serious consideration in all patients older than 65 requiring cardiopulmonary bypass.

Abstract
BACKGROUND Lower ministernotomy has become a more popular approach for many heart operations. However, cannulation of the ascending aorta may cause serious complications. Femoral and brachial arteries have been used for alternative arterial cannulation sites. MATERIALS AND METHODS The lower ministernotomy approach was used in 65 patients. Ascending aortic cannulation was performed in group 1 (n = 38), femoral cannulation in group 2 (n = 12), and brachial cannulation in group 3 (n = 15) patients. Brachial artery diameter was measured preoperatively by Doppler ultrasound in the preoperative period. RESULTS Average cross-clamp time for femoral and brachial artery cannulated patients was significantly shorter than in patients in group 1 (31 +/- 9 and 35 +/- 6 minutes, respectively) (p = 0.034). Total cardiopulmonary bypass (CPB) time was 56 +/- 11 minutes for group 1, 39 +/- 7 minutes for group 2, and 41 +/- 5.4 minutes for group 3 (p = 0.041). Operation time was 112 +/- 24, 88 +/- 12, and 91 +/- 11 minutes for the groups 1, 2, and 3, respectively. There was also statistically significant difference between group 1 and group 3 comparisons with regard to CPB time (p = 0.041). Difficult exposure from many cannulas impedes access and lengthens the operation in group I. Superficial wound infection developed in seven patients in group 1, one patient in group 2, and one patient in group 3. CONCLUSION Cannulation of the brachial artery is superior to the femoral due to possible infection and lymph leakage with the latter and both are superior to central cannulation when lower ministernotomy is performed. By avoiding the difficulties of central aortic cannula placement the operative time is decreased and possible wound edge is protected as lesser exposure is required.

Abstract
OBJECTIVE To evaluate cerebral perfusion using direct cannulation into the common carotid artery. A new technique is needed to protect brain ischemic injury during ascending aortic or aortic arch replacement. METHODS This technique was evaluated for patients who would have difficulty maintaining adequate cerebral perfusion during surgery. The procedure was performed when patients had the following diagnoses: pseudoaneurysm formation in contact with the sternum with the risk of aneurysmal rupture (n = 5), acute aortic dissection with compression of the true lumen of the innominate artery by the pseudolumen (n = 3), or a large volume of thrombus in the lumen of the aneurysm with the risk of cerebral thromboembolism if standard extracorporeal circulation was used (n = 2). The perfusion catheter was cannulated into one side of the common carotid artery (right side: n = 6, left side: n = 4) and mean perfusion flow rate was found to be 175 mL/min. The operative procedures consisted of ascending aortic and aortic arch replacement with coronary artery bypass grafting in six patients, ascending aortic replacement in 2 patients, and innominate artery reconstruction/innominate artery and right subclavian artery reconstruction in one patient. RESULTS No cerebral accidents or deaths occurred while patients were hospitalized. We have followed up patients for a mean of 2.1 years (maximum 3.6 years), with no complications noted from the surgical procedure. CONCLUSIONS Direct cannulation of the common carotid artery is a simple, safe, and acceptable cerebral protection for patients undergoing aortic or aortic arch replacement procedures in the patients with these specific conditions.

Abstract
The axillary artery is an alternative site for arterial cannulation that avoids manipulation of the ascending aorta or aortic arch and provides antegrade blood flow during surgery for acute type A aortic dissection. Right axillary artery cannulation has been used in 27 patients for arterial perfusion. There were no complications related to the technique of axillary cannulation. All patients but one awoke neurologically intact from operation and suffered no complications. Hospital mortality occurred in two (7.4%) patients. Axillary cannulation is easy to establish and may safely be used for arterial inflow during surgery for acute type A dissection of the ascending aorta.

Abstract
BACKGROUND To determine the effectiveness of unilateral selective cerebral perfusion for aortic arch repair and to discuss possible modifications to enhance technical simplicity. METHODS In the period between January 1996 and April 2001, 104 patients underwent aortic arch repair with the use of right brachial artery low flow (8 to 10 mL/kg per minute) antegrade selective cerebral perfusion under moderate hypothermia (26 degrees C). Mean patient age was 52 +/- 12 years. Sixty-four patients presented with Stanford type A aortic dissection, including 12 with acute dissection; 38 patients had aneurysmal dilatation of the ascending aorta and aortic arch; and 2 patients had isolated arch aneurysm. Ascending and partial arch replacement was performed in 50 patients; ascending and total arch replacement in 33 patients; ascending and descending arch replacement in 19 patients; and isolated arch replacement in 2 patients. RESULTS Mean antegrade cerebral perfusion time was 39 +/- 22 minutes. One patient with acute proximal dissection died because of cerebral complications. One other patient developed right hemiparesis, which resolved during the second postoperative month without sequela. Other than these 2 cases (1.9%), no other neurologic event was observed. CONCLUSIONS The technique of low flow antegrade selective cerebral perfusion through the right brachial artery may be used for a vast majority of aortic aneurysms and dissections requiring arch repair. This technique does not necessitate deep hypothermia, requires shorter cardiopulmonary bypass and operation times, has the advantage of simplicity, provides optimal vascular repair without time restraints and, in terms of clinical results, is as safe as other techniques for cerebral protection.

Abstract
BACKGROUND In aortic operations performed through a left thoracotomy, which require total bypass and deep hypothermic circulatory arrest, femoral artery cannulation is commonly used for arterial perfusion. This route limits the time of safe circulatory arrest and is associated with the risks of retrograde embolization or, in the case of aortic dissection, malperfusion of the vital organs. To overcome these problems, we have used cannulation of the extrathoracic left common carotid artery to ensure a central a route of arterial perfusion in these operations. The preliminary results are presented. METHODS Between December 1999 and April 2001, we used left common carotid artery cannulation in 26 operations on the thoracic aorta performed through a posterolateral thoracotomy with an open technique during deep hypothermic circulatory arrest. Institutional review board approval and informed consent were obtained. The indications included perforating atherosclerotic ulcer (n = 5), chronic aortic aneurysm (n = 9), acute type B aortic dissection (n = 3), and chronic dissection of the thoracic aorta (n = 9). Transcranial Doppler ultrasonographic monitoring of both the right and left middle cerebral arteries was used to assess the adequacy of cerebral bihemispheric perfusion and to determine the differences in blood flow velocities throughout the procedure. RESULTS Left common carotid artery cannulation was successful in all patients. All patients awoke from the operation, and none had cerebrovascular accidents. None died in the hospital, and complications related to carotid artery cannulation were not observed. None of the patients experienced postoperative paraplegia. In all patients transcranial Doppler monitoring indicated the absence of cerebral embolic phenomena throughout the entire procedure. Significant differences in middle cerebral artery flow velocities were observed at different phases of the procedures and between the right and left middle cerebral arteries during carotid cannulation and during selective cerebral perfusion. Nevertheless, the maximal drop of right middle cerebral artery blood velocity during selective perfusion through the left common carotid artery was within 50% of the left middle cerebral artery velocity, indicating adequate bihemispheric perfusion. CONCLUSIONS In patients undergoing aortic operations through a left thoracotomy, extrathoracic left common carotid artery cannulation was a safe and effective means of providing proximal arterial inflow during cardiopulmonary bypass, which can be used to selectively perfuse the brain, as well as to prevent embolic phenomena in the arch vessels.

Abstract
BACKGROUND Reoperative coronary artery bypass grafting (CABG) through a left thoracotomy is a challenging operation with no one dominant approach. We developed a tailored strategy for this difficult group of patients, integrating the currently available newer technologies for each patient indication. METHODS Between October 1991 and October 1999, 50 consecutive patients underwent reoperative CABG through a left thoracotomy. Age was 65 +/- 9 years, 40 (80%) were men, and preoperative ejection fraction was 40 +/- 13. In 36 patients (72%) the left internal mammary artery had been placed to the left anterior descending coronary artery during the primary CABG and in 25 of 36 patients (70%) this left internal mammary artery-left anterior descending coronary artery graft was patent. The mean duration from previous CABG was 8.0 +/- 4.8 years. Three approaches were used: (1) conventional cardiopulmonary bypass using fibrillatory or circulatory arrest (n = 33, 66%); (2) Heartport endoaortic balloon occlusion (n = 4, 8%); and (3) off-pump beating heart techniques (n = 13, 26%). RESULTS The off-pump CABG technique was used in the majority of recent patients and 1 (7.7%) had to be converted to cardiopulmonary bypass due to hemodynamic instability. When cardiopulmonary bypass was used its duration was 122 +/- 59 minutes and mean temperature on bypass was 24 degrees +/- 6 degrees C. In the 4 patients in whom the Heartport system was used, the median endoaortic occlusion duration was 49 minutes. Patients received an average of 1.4 grafts/patient. In 60 of 70 patients (89%) distal anastomoses were performed to an anterolateral coronary target. There were 3 of 50 (6%) operative deaths, 2 in the conventional group and 1 in the endoaortic balloon occlusion group. The mean length of stay in the 47 survivors was 7.8 +/- 3.9 days (median, 7 days). CONCLUSIONS Reoperative CABG by left thoracotomy remains a challenging operation. Several techniques, including off-pump CABG, conventional cardiopulmonary bypass, circulatory arrest, and endoaortic balloon occlusion, should be in the surgeon's armamentarium to allow a tailored approach for each operation based on patient indications.

Abstract
We report our entire experience with minimal access aortic root, valve, and complex ascending aortic surgery. A total of 290 consecutive patients underwent aortic root, valve, and ascending aortic surgery between July 1996 and February 2000. Four groups were identified: isolated aortic valve replacement (AV group, n = 227), aortic root replacement (AR group, n = 44), aortic valve replacement with concomitant replacement of the supracoronary ascending aorta (V/A group, n = 9), and isolated ascending aortic replacement (AA group, n = 10). The procedures were performed through a partial upper hemisternotomy (87%) or a right parasternal approach (13%). Overall mortality was 3.1% (n = 7) for the AV group, 2.3% (n = 1) for the AR group, 0% for the V/A group, and 10.0% (n = 1) for the AA group. Complications included reoperation for bleeding in 10 (4.5%), two (4.7%), one (11.1%), and one (11.1%) for the four groups respectively; and sternal wound infection in eight (3.6%) patients of the AV group and one (2.3%) patient of the AR group. Five (2.3%) patients of the AV group suffered stroke. Isolated or more complicated aortic valve, root and ascending aortic surgery is feasible and safe through a minimally invasive approach with acceptable incidence of complications and mortality, without compromising the efficacy of the procedure.

Abstract
OBJECTIVE We developed techniques for 'inverted T' partial upper re-sternotomy for aortic valve replacement (AVR) or re-replacement (AVreR) after previous cardiac surgery. We previously reported on decreased blood loss, transfusion requirements and total operative duration when compared to conventional full re-sternotomy. This report updates our series, one of the few to document a substantial benefit from a 'minimally-invasive' approach, refines a number of technical aspects of this new approach and reports follow-up. METHODS Between November 1996 and December 1999, we performed 34 AVRs or AVreRs after previous cardiac surgery by use of an 'inverted T' partial upper re-sternotomy. There were 25 (74%) men. Median ejection fraction was 54%, range 15-80%. Median age was 72, range 38-93. All were New York Heart Association functional class (NYHA) functional class II or III. Twenty-one (62%) had previous coronary artery bypass grafts (CABG) while 14 (41%) had previous valve surgery. Follow-up was 100% complete for a total of 593 patient months (median 19 months). RESULTS Twenty-three (66%) underwent AVR of the native aortic valve while 11 (33%) underwent AVreR of a prosthetic aortic valve. There were no intraoperative or valve-related complications, and no conversion to full re-sternotomy was necessary. There were two (5.9%) operative deaths from an arrhythmia on postoperative day 4 and a large stroke during surgery, respectively. Twenty-four (75%) patients were free of major complications. There was no need for reoperation for bleeding and patients required a median of two units of packed red blood cells. Complications included new atrial fibrillation (n=3, 9%), pacemaker implantation (n=3, 9%) and deep sternal wound infection (n=2, 6%). Median lengths of stay in the intensive care unit (ICU) and in the hospital were 1 and 7 days, respectively. There was one (3%) late deep sternal wound infection and 2/32 (6%) late deaths due to congestive heart failure at 22 months and myocardial infarction at 23 months, respectively. CONCLUSIONS Partial upper re-sternotomy presents a safe and effective alternative approach to AVR and AVreR after previous cardiac surgery, and is associated with low morbidity and mortality.

Abstract
Perfusion from the femoral artery is commonly used in the open proximal method of performing distal aortic arch aneurysm repair or Stanford type B aortic dissection repair under circulatory arrest through left thoracotomy. However, it is associated with a significant risk of retrograde emboli or malperfusion, and with other problems including a restricted time of circulatory arrest to the brain and difficulties in de-airing from the arch branches and proximal ascending aorta. To overcome these problems, we developed a method of performing right axillary perfusion through left thoracotomy.

Abstract
BACKGROUND Standard cannulation of the femoral artery in preparation for repair of a dissection involving the ascending aorta carries a high risk of malperfusion. Arterial perfusion through the right axillary artery is more likely to perfuse the true lumen and should be advantageous in acute dissections involving the ascending aorta. METHODS Thirteen patients underwent repair of acute ascending aortic dissections and were perfused through the right axillary artery. All had deep hypothermic circulatory arrest. RESULTS There was one mild intraoperative cerebrovascular accident with complete recovery and one operative death secondary to low cardiac output. There were no intraoperative problems with perfusion through the axillary artery, and there were no postoperative problems or complications involving the axillary artery, axillary vein, or brachial plexus. CONCLUSIONS Arterial perfusion through the right axillary artery is a safe and effective means of more reliably perfusing the true lumen. In this regard, it may be superior to femoral artery perfusion and could lead to improved outcomes with repair of acute deBakey type I and II aortic dissections.

Abstract
The results of surgical treatment for a ruptured type B aortic dissection remain far from satisfactory. It is believed that additional perfusion from the right axillary artery might be more beneficial than perfusion from only the femoral artery during surgery for a ruptured thoracic aneurysm. The right axillary perfusion is more likely to perfuse the vital organs proximal to the ruptured area, and thus avoid retrograde emboli. In addition, if the open proximal method is performed, then the right axillary perfusion is able to facilitate the evacuation of air from the aortic lumen. We present herein the case of a patient in whom a ruptured type B acute aortic dissection was successfully treated by applying right axillary perfusion through a left thoracotomy.

Abstract
BACKGROUND Mitral valve surgery after previous coronary artery bypass grafting presents a challenging problem for the cardiac surgeon. An injury to patent coronary artery bypass grafts, especially internal mammary artery grafts, during reoperation via a redo sternotomy, may be fatal. Therefore, a reliable alternative to the redo sternotomy is desirable to minimize potential injury to internal mammary artery grafts. METHODS Between February 1987 and October 1998, we performed 59 consecutive mitral valve operations after previous coronary artery bypass grafting surgery (CABG). A total of 24 patients (41%) had functioning internal mammary artery (IMA) grafts and represent the population for this study. No patients were excluded for any reason. Of the 24 patients, 20 (83%) were men. Mean age was 66+/-13 years (range 41 to 83 years) and the mean duration from CABG was 5.3+/-3.6 years (range 0.1 to 12 years). Four (17%) had functioning bilateral internal mammary artery grafts. All had 3 to 4+ mitral regurgitation (MR) at the time of mitral valve surgery and the mean preoperative ejection fraction (EF) was 40%+/-14% (range 20% to 74 %). RESULTS Twenty-one (88%) patients underwent mitral valve surgery through an anterolateral right thoracotomy and 3 (12%) through a redo sternotomy. Twenty-two (92%) patients, including the 3 patients in whom a redo sternotomy was used, had cannulation of the femoral artery and vein. Two patients required axillary artery cannulation. All 21 patients in whom the mitral valve was approached through a right thoracotomy underwent deep hypothermia (19.6 degrees+/-2.1 degrees C, range 14 degrees to 25 degrees C) without aortic clamping, with a mean duration of CPB of 138+/-46 minutes (range 65 to 249 minutes). In 18 (75%), the MR was ischemic in origin and in 6 (25%) there was myxomatous degeneration. Nine (34%) required valve replacement and 15 (66%) underwent repair. There were no operative or hospital deaths and all patients were discharged to home or to a rehabilitation facility. There were 4 (17%) major complications. Two patients suffered respiratory failure requiring tracheotomy, 1 patient developed a perioperative MI requiring an intraaortic balloon pump and 1 developed heart block requiring a permanent pacemaker. There were no neurologic, peripheral vascular, bleeding, or wound complications. CONCLUSIONS Reoperative mitral valve surgery in the setting of functioning IMA grafts, even in the face of depressed LV function, can be done safely and with minimal morbidity.

Abstract
OBJECTIVE We developed techniques for partial upper hemisternotomy for reoperative aortic valve replacement and compared the results with those of reoperative aortic valve replacement by way of conventional full resternotomy. METHODS We retrospectively analyzed data from 19 patients who underwent conventional full sternotomy and 20 patients who underwent partial hemisternotomy for isolated elective reoperative aortic valve replacements performed between November 1996 and September 1998. Univariable and multivariable analyses were used to document the differences between the groups. RESULTS The 2 groups were similar with respect to age, sex, New York Heart Association functional class, valve pathologic characteristics, and numbers and types of previous operations. There were neither any operative deaths nor any postoperative valve-related morbidities in either group. There was 1 injury to a cardiac structure, which occurred in the conventional full sternotomy group. Univariable analysis documented that patients in the conventional full sternotomy group were significantly more likely to have at least 1000 mL blood loss during the first 24 hours after the operation (odds ratio 8.1, P =.02), were more likely to require transfusion of more than 5 units of packed red blood cell (odds ratio 3.6, P =.08), and were more likely to have a total operative duration longer than 5 hours (odds ratio 3.6, P =.08). In the multivariable analysis conventional full resternotomy remained a risk factor for greater blood loss (odds ratio 5.7, P =.06), greater transfusion requirement (odds ratio 2.4, P =.25), and longer total operative duration (odds ratio 7.7, P =.03). CONCLUSIONS Partial upper hemisternotomy for reoperative aortic valve replacement avoids unnecessary lower mediastinal dissection, thereby reducing blood loss, transfusion needs, and total operative duration. These beneficial effects, which are accomplished without compromising the efficacy of the valve operation, make the partial upper hemisternotomy an excellent alternative to conventional full resternotomy for reoperative aortic valve replacement.

Abstract
OBJECTIVE Minimally invasive open heart surgery involves limited intrathoracic cannulation sites necessitating cardiopulmonary bypass to be initiated via peripheral access using percutaneous cannulae with the tip placed into the right atrial cavity. However, surgery involving the opening of the right heart obliges the surgeon to maintain the end of the cannulae into the vena cavae. The impeded venous return due to the smaller diameter may be alleviated by inserting a centrifugal pump in the venous line. METHODS Right anterior mini-thoracotomy and exposure of the femoral site were performed before the patient was heparinized. Cannulation of the femoral artery, the inferior vena cava via the femoral vein and the superior vena cava through the mini-thoracotomy was performed and cardiopulmonary bypass was initiated. Venous drainage was augmented with the centrifugal pump. Cardiac arrest was provoked and both vena cavae were snared before performing the intracardiac procedure. RESULTS Twenty consecutive patients were operated on using this technique (15 males/five females; age: 44.8 +/- 14.3 years; bodyweight: 73.5 +/- 15.1 kg; body surface area: 1.8 +/- 0.2 m2; theoretical blood flow rate: 4.4 +/- 0.5 l/min). The cannula sizes were 21.9 +/- 2.2 Fr for the femoral artery, 26.5 +/- 1.7 Fr for the inferior vena cava and 23.8 +/- 2.5 Fr for the superior vena cava. Venous drainage through the single inferior vena cava cannula was 2.1 +/- 0.6 l/min (48.8 +/- 13.3% of the theoretical flow). Adding the superior vena cava cannula increased the venous flow to 3.1 +/- 0.4 l/min (70.7 +/- 9.6% of the theoretical value, P < 0.005). The use of the centrifugal pump increased the flow to 4.1 +/- 0.6 l/min (93.4 +/- 8.9% of the theoretical flow, P < 0.001) with a mean inlet negative pressure of -69 +/- 10.2 mmHg. The mean bypass time was 64.0 +/- 24.6 min for a mean operative time of 226.3 +/- 61.0 min. Minimum venous saturation was 69.4 +/- 8.5%. CONCLUSIONS Despite the smaller diameter of the vena cavae compared to the right atrium, and a smaller internal diameter of percutaneous cardiopulmonary bypass cannulae compared to classic ones; the centrifugal pump improves the venous drainage significantly so that minimally invasive open heart procedures can be performed under optimal and safe perfusion conditions.

Abstract
BACKGROUND Femoral arteries are the preferred site of peripheral cannulation for arterial inflow in type A aortic dissection operations. The presence of aortoiliac aneurysms, severe peripheral occlusive disease, atherosclerosis of the femoral vessels, and distal extension of the aortic dissection may preclude their utilization. Axillary artery cannulation may represent a valid alternative in these circumstances. METHODS Between January 15, 1989, and August 20, 1998, in our institution, 22 of 152 operations (14.4%) for acute type A aortic dissection were performed with the use of the axillary artery for the arterial inflow. Axillary artery cannulation was undertaken in the presence of femoral arteries bilaterally compromised by dissection in 12 patients (54.5%), abdominal aorta and peripheral aneurysm in 5 patients (22.7%), severe atherosclerosis of both femoral arteries in 3 patients (13. 6%), and aortoiliac occlusive disease in 2 patients (9.1%). In all patients, distal anastomosis was performed with an open technique after deep hypothermic circulatory arrest. Retrograde cerebral perfusion was used in 9 patients (40.9%). RESULTS Axillary artery cannulation was successful in all patients. The left axillary artery was cannulated in 20 patients (90.9%), and the right axillary artery was cannulated in 2 patients (9.1%). Axillary artery cannulation followed an attempt of femoral artery cannulation in 15 patients (68. 2%). All patients survived the operation, and no patient had a cerebrovascular accident. No axillary artery thrombosis, no brachial plexus injury, and no intraoperative malperfusion were recorded in this series. Two patients (9.1%) died in the hospital of complications not related to axillary artery cannulation. CONCLUSIONS In patients with type A aortic dissection in whom femoral arteries are acutely or chronically diseased, axillary artery cannulation represents a safe and effective means of providing arterial inflow during cardiopulmonary bypass.

Abstract
OBJECTIVE Although cannulation of the femoral artery is used routinely for thoracic aortic operations with hypothermic circulatory arrest, retrograde perfusion through the descending aorta carries the risk of cerebral malperfusion or embolism. We have, therefore, routinely used a central cannulation technique for distal arch and descending aortic operations since 1995. In this study, we compared neurological outcome in consecutive patients undergoing femoral versus ascending aortic perfusion for these aneurysms. METHODS Between 1987 and 1998, 61 patients underwent aortic resection with circulatory arrest, but without retrograde cerebral perfusion, for lesions of the aortic arch and descending aorta. Thirty-one patients had fusiform true aneurysms, 19 had aortic dissection and 11 had extensive saccular or false aneurysms. Thirty-two patients (52%) were perfused via the femoral artery (group A), and 29 patients (48%) from the ascending aorta (group B). Operative mortality and morbidity, and neurological outcome, were reviewed. RESULTS There were no differences between the groups in mean age, pathology, abdominal and peripheral vascular disease, net perfusion time, or circulatory arrest time. There were four hospital deaths (three in group A and one in group B; P = 0.61), including one neurological death in group A, group A suffered a higher incidence of neurological events (nine patients: 28%) than group B (two patients: 7%; P = 0.03). Temporary focal neurological deficits occurred in both groups (two patients in group A, 6% and two patients in group B, 7%; P > 0.99), but permanent injury occurred exclusively in group A (seven patients: four with monoplegia, one with hemiplegia, and two with diffuse cerebral injury with one death; P = 0.01). CONCLUSIONS Anterograde perfusion using a proximal aortic cannula provides a low risk of cerebral embolism and allows extensive aortic resection with low morbidity.

Abstract
Repeat open-heart operations are becoming more frequent with a patient population at higher risk. Sternal re-entry poses the risk of possible damage to vital structures. These include laceration of the myocardium, especially the right ventricle, tearing of patent grafts and internal mammary grafts in particular, or dislodgement of emboli from patent vein grafts. To minimize the risk associated with sternal re-entry, we adopted the method of establishing femoral artery-femoral vein cardiopulmonary bypass (CPB) in order to achieve cardiac decompression prior to sternotomy. Between June 1994 and October 1997, 94 patients underwent repeat open-heart operations at our institution. Of these, seven were a second time reoperation. Mean age was 62 years (range 31-80 years), and 65 were male. Fifty-nine patients had coronary bypass, 27 had aortic valve replacement, 45 had mitral valve replacement, and nine had other procedures (these numbers include patients having combined procedures). In patients with no known vascular disease, the femoral vessels were exposed, and if found suitable, were cannulated, and the patients connected to CPB. The sternum was opened with an oscillating saw, and on penetration through the posterior table, the heart was drained to allow for decompression. If the femoral vein cannula did not allow full bypass, ventilation was maintained until the right atrium was exposed and cannulated and full bypass was achieved. Femoro-femoral bypass was established in 75 patients. In 19 patients it was not done for the following reasons: eight patients had a diseased femoral artery, in one patient the femoral vein could not be cannulated, nonuse of CPB altogether occurred in three patients, and it was because of surgeon's preference in seven patients. In one patient a high pressure developed in the arterial line, requiring conversion to aortic cannulation during the course of CPB, without any negative consequences. There were no problems associated with sternal re-entry, no patient had limb ischemia or venous thrombosis. Two patients (2.6%) had complications related with femoral cannulation, with one having trauma to an atherosclerotic femoral artery requiring repair with vein interposition, and the other a tear of iliac vein requiring laparotomy. Groin wound infection occurred in five patients (6.6%), and groin hematoma in four patients (5.3%). All complications were treated successfully with no permanent damage. Operative mortality was 9% (seven patients). Causes of death included myocardial infarction (2), infection (3), respiratory (1), and cirrhosis (1). We conclude that femoro-femoral bypass prior to sternotomy is a safe and easy method to reduce the risk of sternal re-entry by allowing early decompression of the heart, and in unstable patients it offers better myocardial protection by earlier connection to CPB. Proper selection of patients is important in order to minimize related comorbidity. We recommend this method in redo patients in whom femoral cannulation is feasible.

Abstract
As a result of reports touting the effectiveness of minimally invasive valve operations, many cardiovascular surgeons and their patients are beginning to believe that smaller incisions are always better. According to its proponents, the minimally invasive approach results in less pain, a faster recovery, and a more satisfactory cosmetic result. Proponents also believe that the operation can be done safely and effectively at a lower cost than traditional surgical approaches. This may not be the case, however, and additional prospective studies must be done before firm conclusions can be drawn. For example, cardiopulmonary bypass, myocardial ischemia, and overall operative times are significantly longer (40% or more) for minimally invasive surgical procedures. Morbidity and mortality rates do not appear to be decreased, the length of hospital stay varies by only 1 or 2 days, and patients do not necessarily report less postoperative pain. When the conventional technique is used, the operation can be performed precisely and expeditiously. Should complications occur, the surgeon will have direct access to the heart. The cost of a conventional procedure should not be much more than that of a minimally invasive procedure, and in some instances it may even be less-particularly when the less invasive procedure significantly extends the operating room time or requires additional monitors or costly disposables.

Abstract
The duration of safe circulatory arrest for replacement of the ascending aorta for a type A dissection, without additional cerebral perfusion measures, is not clearly defined. If prolonged periods (> 60 minutes) are anticipated, retrograde cerebral perfusion or selective antegrade carotid perfusion may be required. The latter requires separate cannulas with subsequent snaring of the cerebral vessels, which may be time consuming and cumbersome. We propose an alternative method whereby the right axillary artery is cannulated for cardiopulmonary bypass and, when the desired hypothermic temperature is achieved, the flows are turned down to 500 mL/min. The origin of the innominate artery is then occluded establishing selective antegrade right carotid artery perfusion. The distal ascending or aortic arch anastomosis is then performed while the remainder of the body is under selective systemic circulatory arrest. The proximal aortic anastomosis is performed after the graft is clamped proximally and flows return to appropriate perfusion levels.

Abstract
BACKGROUND Aortic valve replacement or repair becomes a high-risk procedure in patients in whom the ascending aorta cannot be clamped either because of extensive calcification and risk of cerebral embolus or because of extensive adhesions precluding safe dissection and clamping. METHODS We report the results of aortic valve replacement or repair with deep hypothermic circulatory arrest in 3 patients. Techniques to improve results include routine use of epiaortic and transesophageal echocardiography, avoidance of manipulation of the ascending aorta until the circulation is arrested, avoidance of antegrade cardioplegia, routine use of retrograde cardioplegia and retrograde cerebral perfusion, when feasible, and minimal aortotomy (just enough to excise and replace or repair the valve). RESULTS Operations were accomplished in approximately 1 hour each with minimal manipulation of the aorta, thus minimizing aortic trauma and subsequent risk of cerebral embolus. Each patient had an unremarkable recovery without neurologic complications. CONCLUSIONS Aortic valve replacement or repair using the "no-touch" technique and deep hypothermic circulatory arrest is the preferred method when dealing with the porcelain or unclampable aorta.
