RESUMO
BACKGROUND: We studied the incidence of primary graft dysfunction (PGD), its impact on in-hospital and follow-up outcomes and searched for independent risk factors. METHODS: During an 18-year period, 508 individuals underwent heart transplantation at our institution. Patients were diagnosed with none, mild, moderate or severe PGD according to ISHLT criteria. RESULTS: Thirty-eight patients (7.5%) met the ISHLT criteria for mild PGD, 92 (18.1%) for moderate PGD and 23 (4.5%) for severe PGD. Patients were classified into none/mild PGD (77.4%) and moderate/severe PGD (22.6%) groups. In-hospital mortality was 12.4% (7.8% for none/mild PGD and 28.7% for moderate/severe PGD; p < .001). Survival at 1, 5, and 15 years was 85.5 ± 1.9% versus 67.2 ± 4.5%, 80 ± 2.2% versus 63.5 ± 4.7%, and 60.4 ± 3.6% versus 45.9 ± 8.4%, respectively (p < .001). Excluding the events occurring during the first month of follow-up, survival was comparable between the two groups (93.1 ± 1.4% vs. 94.7 ± 2.6 at 1 year and 65.6 ± 3.8% vs. 70.4 ± 10.4% at 15 years, respectively; p = .88). Upon multivariate logistic regression analysis preoperative mechanical circulatory support (odds ratio [OR] = 5.86) and preoperative intra-aortic balloon pump (IABP) (OR = 9.58) were independently associated with moderate/severe PGD. CONCLUSIONS: Our results confirm that PGD is associated with poor in-hospital outcome. The poor outcome does not extend beyond the first month of follow-up, with comparable survival between patients with none/mild PGD and moderate/severe PGD in the short and long-term. Mechanical circulatory support and preoperative IABP were found to be independent risk factors for moderate/severe PGD.

An easily reproducible surgical technique to switch from percutaneous minimally invasive biventricular mechanical support to cardiopulmonary bypass during heart transplantation is illustrated. After cannulation of the distal ascending aorta with a standard arterial cannula, the ProtekDuo® cannula and the ProtekSolo® Transseptal cannula were partially retracted to reach the superior and inferior vena cava, respectively, and connected to the pump circuit for the venous drainage. With this cardiopulmonary bypass configuration, orthotopic heart transplantation was routinely performed and, at the end of the procedure, the 2 cannulas were uneventfully removed.

Acute aortic syndrome includes three main pathological conditions: aortic dissection (AD), intramural hematoma (IMH) and penetrating aortic ulcer (PAU). These are life-threatening conditions, therefore early diagnosis and interventional/surgical treatment are fundamental for the survival of affected individuals. While anatomical findings of classical AD provided by imaging techniques are known to all cardiologists, imaging findings of IMH and PAU are less known, as are their prognostic implications and consequences on management and treatment strategies. This review aims to describe and discuss findings and role of imaging techniques in patients with IMH and PAU.

Type A acute aortic dissection (TA-AAD) is a catastrophic condition for which emergency surgery is the mainstay of therapy. Surgical treatment of TA-AAD is centered on excision of the proximal intimal tear, replacement of the ascending aorta and re-establishment of a dominant flow in the distal true lumen. In patients who survive surgery, a dissected distal and/or proximal aorta remains, posing a risk of subsequent aneurysmal degeneration, rupture and malperfusion, and secondary extensive interventions are often required. However, knowledge regarding the risk factors of progression of residual aortic dissection is limited, and no well-defined recommendations for clinical and imaging follow-up have been generated thus far. The aim of this paper is to review and discuss on the current evidence and controversies on the long-term management of patients operated on for TA-AAD.

Although the indications for surgical management of severe functional tricuspid regurgitation (TR) are now generally accepted, controversy persists concerning the role of intervention for moderate TR. However, there is a trend for intervention in this setting, particularly in patients with annular dilation. Echocardiographic imaging is the gold standard to identify functional TR and distinguish it from a primitive or degenerative form. Currently, surgery remains the best approach for the interventional treatment of TR. Ring annuloplasty seems to provide better results than suture annuloplasty (De Vega technique) and rigid rings appear to be more reliable in the long term, in comparison with flexible bands. Tricuspid valve repair is more beneficial compared with replacement, except in highly selected cases of long-standing TR with multifactorial mechanism.

Coverage of the left subclavian artery in thoracic endovascular aortic repair is still a controversial procedure. We report a case of 30-year-old patient with a chronic rupture of the aortic isthmus and short proximal lending zone (10 mm) treated by thoracic endovascular aortic repair using a balloon catheter inflated at the origin of the left subclavian artery (and protruding in the aortic arch) to both preserve the arterial branch patency and fully exploit the proximal neck.

BACKGROUND: We assessed whether additional cusp repair during valve-sparing aortic root replacement affects the echocardiographic mid-term results; a subgroup analysis among patients with bicuspid aortic valve (BAV) and tricuspid aortic valve (TAV) was performed. METHODS: Between June 2002 and May 2015, 157 consecutive patients underwent valve-sparing aortic root replacement with the David technique. Thirty patients (19%) had BAV. In 19 patients (12%), cusp motion or anatomic abnormalities contributed in determining aortic regurgitation requiring an additional cusp repair. Mean follow-up was 7 ± 3.4 years. RESULTS: The cumulative 1-, 5-, and 12-year survival rates were 98%, 94%, and 90%, respectively. Fourteen patients (9%) required aortic valve replacement during follow-up. In 2 patients the underlying cause was bacterial endocarditis. Freedom from aortic valve reoperation was 96% at 1 year, 92% at 5 years, and 89% at 12 years. Reoperation rate was significantly higher (p < 0.001) in patients who received leaflet repair compared with patients who did not, with a freedom from reoperation at 8 years of 58% versus 94%. Among patients with BAV, those who did not require cusp repair had a freedom from reoperation at 8 years of 94%, with a significant difference compared with patients who received cusp repair (p = 0.04). Cusp repair did not affect reoperation risk in patients with tricuspid aortic valve. CONCLUSIONS: Adjunctive cusp repair seems to affect the mid-term reoperation risk in patients with BAV and not in patients with tricuspid aortic valve. We recommend caution in using this technique in case of asymmetric BAV requiring cusp repair.

OBJECTIVE: To shed light on contemporary results of open total aortic arch surgery, we undertook a systematic review to identify all reports on this procedure published in the last 10 years. METHODS: Extensive electronic literature search was undertaken to identify all published articles from 2004 to 2014 that provided results on total aortic arch replacement. According to inclusion and exclusion criteria, 21 relevant studies were selected and meta-analyzed to assess outcomes. RESULTS: The pooled estimate for operative mortality was 5.3%. Permanent and transient neurologic deficit occurred postoperatively at a pooled rate of 3.4% and 5.2%, respectively. Pooled rate of irreversible spinal cord injury was 0.6%, whereas renal failure occurred at a pooled rate of 4.1%. Prolonged intubation occurred at pooled rate of 15.4%. Among elective patients, pooled rate of mortality and permanent neurologic deficit was 2.9% and 2.2%, respectively, with a significant difference compared with urgent/emergency surgery cases. CONCLUSIONS: The main findings from this meta-analysis indicate that total aortic arch replacement can be performed with satisfactory mortality and morbidity. The pooled rates of mortality and permanent neurologic deficit among elective cases were surprisingly low, and these data have an even greater prominence when they are compared with outcomes of hybrid arch series. Under urgent/emergency surgery, early mortality and neurologic complications showed an about threefold higher rate. Moderate hypothermic circulatory arrest and early rewarming seem to provide proper renal protection, with an intermediate risk of prolonged intubation.

BACKGROUND: To determine whether the hybrid approach to acute type A aortic dissection results in improved outcomes in terms of mortality, neurologic complications, need for distal aortic reintervention, and false lumen thrombosis compared with the conventional approach. METHODS: Data from comparative studies of hybrid versus conventional treatment of acute type A aortic dissection were combined through meta-analysis. Pooled odd ratios were calculated using random effects models. RESULTS: Seven comparative studies including 967 patients were identified; of these, 503 underwent conventional proximal aortic repair and 429 extensive distal aortic repair including a stented elephant trunk technique. Between the two groups there was no significant difference in operative mortality (p = 0.96), permanent neurologic deficit (p = 0.95), and late mortality (p = 0.59). Distal aortic repair showed a higher rate of false lumen thrombosis of the thoracic aorta (odd ratio 11.16; p < 0.001) and a reduced risk of distal reintervention (odd ratio 0.37; p = 0.01). In sub-group analysis, frozen elephant trunk procedure showed a lower rate of distal aortic reintervention and a higher rate of false lumen thrombosis than antegrade/retrograde stent deployment techniques (p = 0.008 and <0.001, respectively). CONCLUSIONS: Distal aortic repair may reduce the risk of distal reintervention and increase the rate of false lumen thrombosis without significant increase in operative mortality and permanent neurologic deficit; however, no benefit with respect to late mortality was found. The frozen elephant trunk may reduce the risk of distal aortic reintervention and may increase the false lumen thrombosis of the thoracic aorta in comparison with antegrade/retrograde stent deployment procedures.

AIMS: Aortic valve-sparing operations are nowadays considered safe and reliable procedures in terms of mid-term and long-term results. Although surgical techniques regarding the modality of grafts' implantation have been properly addressed, the modality of cusp repair, when needed, is still open to debate. We sought to review the literature to try to shed light on when the cusp repair is required and how it should be performed. METHODS: We searched the PubMed database using the keywords aortic valve-sparing operation, aortic valve-sparing reimplantation, valve-sparing aortic root replacement, aortic valve repair, and aortic cusp repair. Only studies that included and described in detail the technique of cusp repairs in adjunct to aortic valve-sparing operation were considered. RESULTS: Bicuspid aortic valve more often requires correction when compared with tricuspid valve. The range of the techniques varies from the 'simple' free margin plication to the more complex triangular resection with patch repair. Results in the literature seem to be encouraging, showing that, in most of the cases, cusp repair does not affect valve competence in the mid-term and long-term. CONCLUSION: Correction of the cusp is a delicate balance between undercorrection that could lead to residual prolapse and overcorrection that could lead to cusp restriction. Although complex repair of the aortic valve in addition to root replacement provided satisfactory results, it should be reserved for experienced centers with a large volume of patients.

AIM: Minimally invasive coronary artery bypass (MIDCAB) allows revascularization of the left anterior descending coronary (LAD) artery through a less traumatic surgical approach. However, the procedure is technically challenging and concern still exists, mainly based on graft patency. The purpose of this study is to critically evaluate short and long-term benefits of this surgical treatment. METHODS: Between June 1997 and July 2012, 306 patients underwent MIDCAB on LAD. The mean age was 62â±â10 years (range, 32-87 years) and 264 patients (86.3%) were men. Mean ejection fraction was 54%. Eighty-nine procedures (29.1%) were performed using a hybrid approach by means of MIDCAB and postoperative (60 patients, 67.4%) or preoperative (29 patients, 32.6%) percutaneous interventions on non-LAD vessels. A EuroScore more than 6 was found in 43 (14%) patients. The average follow-up time was 9.5â±â3.2 years and was 89% complete. RESULTS: Six patients (1.9%) required intraoperative conversion to sternotomy, whereas cardiopulmonary bypass institution after the sternotomy was necessary in one. Postoperative acute myocardial infarction occurring nine patients (2.9%), low output syndrome in four (1.3%). Postoperative mortality was 1.6% (nâ=â5), and perioperative stroke rate 0.6% (nâ=â2). Five and 10-year survival were 94.1 and 86.9%, respectively. Freedom from death due to cardiac events and major cardiac and cerebral events at 10 years was, respectively, 97.1 and 92.1%. CONCLUSIONS: The results confirm the favorable short and long-term results of the MIDCAB procedure. MIDCAB, in experienced centers, can represent an alternative treatment option for LAD disease.

BACKGROUND: The Synergy system, a miniature partial circulatory support device, is implanted by an off-pump, minimally invasive surgical approach. The system has been optimized to improve performance in an EU clinical trial for chronic ambulatory heart failure. This therefore offers the possibility of treating elderly chronic heart failure patients who might not usually be considered for long-term circulatory support. METHODS: From June 2007 to December 2012, 63 patients were implanted with the Synergy system (12 patients ≥70 years) using four different releases of the device. Briefly, the system draws blood through the inflow cannula from the left atrium into the micro-pump (placed in a right subclavicular pocket) and pumps it through an outflow graft to the right subclavian artery. In this paper, we present an intermediate analysis of the clinical trial as performed on April 30, 2013, leading to the placing of the CE mark. RESULTS: Mean duration of support is ongoing at 230 days (range 23-1387). Follow-up showed improved hemodynamic response, with additional improvements in 6-min walk distance (299 ± 144 to 420 ± 119 m) and Minnesota Living with Heart Failure Questionnaire (69.5 ± 20.4 to 49.2 ± 24.3). Older patients had longer mean durations of support (337 vs 188 days). On average, elderly and younger patients showed similar improvements in hemodynamics and 6-min walk distance (107 ± 120 vs 130 ± 121 m). Major adverse cardiac events included bleeding (n=4) with one bleeding related to renal failure resulting in death. CONCLUSIONS: Clinical use of the Synergy device was associated with a significant functional improvement. Very low adverse event rates were reported with the latest device release. Older patients had smaller body sizes and worse renal function than younger patients. Both groups experienced similar hemodynamic benefits and functional improvements. The risk of bleeding and renal dysfunction appears to be increased in the elderly, though still within acceptable ranges compared to other full support devices. Minimally invasive long-term circulatory support devices, like Synergy, offer a new treatment option that might be available even for the elderly chronic heart failure population.

Aortic false aneurysm is a rare complication after cardiac surgery. In recent years, improved results have been reported in regard to the surgical management of these high-risk lesions. We retrospectively examined 28 consecutive cases (in 27 patients) of postsurgical aortic false aneurysm diagnosed at our institution from May 1999 through December 2011. Twenty-four patients underwent reoperation. Cardiopulmonary bypass was instituted before sternotomy in 15 patients (63%). Isolated repair of the aortic false aneurysm was performed in 15 patients. Four patients (including one who had already undergone repeat false-aneurysm repair) declined surgery in favor of clinical monitoring. Eleven patients were asymptomatic at the time of diagnosis. In the other 16, the main cause was infection in 7, and previous operation for acute aortic dissection in 9. The in-hospital mortality rate was 16.6% (4 patients, 3 of whom had infective false aneurysms). Relevant postoperative sequelae were noted in 7 patients (29%). The cumulative 1-year and 5-year survival rates were 83% and 62%, respectively. The 4 patients who did not undergo reoperation were alive at a median interval of 23 months (range, 9-37 mo). Two underwent imaging evaluations; in one, computed tomography revealed an 8-mm increase of the false aneurysm's maximal diameter at 34 months. Aortic false aneurysm can develop silently. Surgical procedures should be proposed even to asymptomatic patients because of the unpredictable evolution of the condition. Radical aortic-graft replacement should be chosen rather than simple repair, because recurrent false aneurysm is possible.

Conversion to a full sternotomy may complicate up to 1.8% of the sternal-sparing coronary artery surgery. Left internal mammary artery injury and anastomotic problems are the common causes. The purpose of this article is to retrospectively review the outcomes of six patients that required conversion to sternotomy during minimally invasive direct coronary artery bypass and also to point out technical aspects in order to avoid such a complication.

A 67-year-old man presented to our hospital with massive mitral and aortic valve prosthetic endocarditis 2 months after transcatheter percutaneous closure of a mitral paravalvular leak with an Amplatzer duct occluder device (AGA Medical Corp, Plymouth MN). He underwent successful reoperation for valve prosthesis replacement and reconstruction of the anterior fibrous trigone. Although transcatheter treatment of periprosthetic valve defects has been shown to be feasible, follow-up data are still limited. This procedure should be reserved only for patients who are not eligible for open surgical procedures and those with small periprosthetic defects.
