RESUMO

BACKGROUND AND AIMS: There is significant potential to streamline the clinical pathway for patients undergoing transcatheter aortic valve implantation (TAVI). The purpose of this study was to evaluate the effect of implementing BENCHMARK best practices on the efficiency and safety of TAVI in 28 sites in 7 European countries. METHODS: This was a study of patients with severe symptomatic aortic stenosis (AS) undergoing TAVI with balloon-expandable valves before and after implementation of BENCHMARK best practices. Principal objectives were to reduce hospital length of stay (LoS) and duration of intensive care stay. Secondary objective was to document patient safety. RESULTS: Between January 2020 and March 2023, 897 patients were documented prior to and 1491 patients after the implementation of BENCHMARK practices. Patient characteristics were consistent with a known older TAVI population and only minor differences. Mean LoS was reduced from 7.7 ± 7.0 to 5.8 ± 5.6 days (median 6 vs. 4 days; P < .001). Duration of intensive care was reduced from 1.8 to 1.3 days (median 1.1 vs. 0.9 days; P < .001). Adoption of peri-procedure best practices led to increased use of local anaesthesia (96.1% vs. 84.3%; P < .001) and decreased procedure (median 47 vs. 60 min; P < .001) and intervention times (85 vs. 95 min; P < .001). Thirty-day patient safety did not appear to be compromised with no differences in all-cause mortality (0.6% in both groups combined), stroke/transient ischaemic attack (1.4%), life-threatening bleeding (1.3%), stage 2/3 acute kidney injury (0.7%), and valve-related readmission (1.2%). CONCLUSIONS: Broad implementation of BENCHMARK practices contributes to improving efficiency of TAVI pathway reducing LoS and costs without compromising patient safety.

RESUMO

INTRODUCTION: Infective endocarditis(IE) has a low incidence, but it remains a serious disease with high mortality rates. Only 5 % of these patients will develop a splenic abscess, and the number of patients that have IE and a splenic abscess requiring surgery is low. The current guidelines recommend that splenectomy should be performed prior to valve replacement, but there is no strong evidence to support this statement and no evidence to clearly endorse the order in which the surgical interventions should be performed. The objective of this review and case series is to establish the proper treatment strategy, to assess the adequate order of the surgical interventions and to clarify the role of percutaneous drainage in the management of these patients. MATERIAL AND METHODS: All patients with infective endocarditis and splenic abscess who underwent surgery in our institution, between January 2008 and December 2020 were included in this study, excluding patients which had cardiac device related endocarditis. Literature review on the matter included a number of 30 studies which were selected from the PubMed database. RESULTS: Assessing the literature and case series no reinfection was reported for simultaneously performing splenectomy(S) and valvular surgery(VS) nor for VS followed by S. CONCLUSION: Percutaneous drainage of the splenic abscesses is a feasible solution as definitive therapy in high-risk patients or as bridge therapy. Additional studies are needed, even though they are difficult to conduct, therefore a national/international infectious endocarditis register may be of use to clarify these challenges.

RESUMO

BACKGROUND: This study aimed to analyse the baseline characteristics of patients admitted with acute type A aortic syndrome (ATAAS) and to identify the potential predictors of in-hospital mortality in surgically managed patients. METHODS: Data regarding demographics, clinical presentation, laboratory work-up, and management of 501 patients with ATAAS enrolled in the National Registry of Aortic Dissections-Romania registry from January 2011 to December 2022 were evaluated. The primary endpoint was in-hospital all-cause mortality. Multivariate logistic regression was conducted to identify independent predictors of mortality in patients with acute Type A aortic dissection (ATAAD) who underwent surgery. RESULTS: The mean age was 60±11 years and 65% were male. Computed tomography was the first-line diagnostic tool (79%), followed by transoesophageal echocardiography (21%). Cardiac surgery was performed in 88% of the patients. The overall mortality in the entire cohort was 37.9%, while surgically managed ATAAD patients had an in-hospital mortality rate of 29%. In multivariate logistic regression, creatinine value (OR 6.76), ST depression on ECG (OR 6.3), preoperative malperfusion (OR 5.77), cardiogenic shock (OR 5.77), abdominal pain (OR 4.27), age ≥70 years (OR 3.76), and syncope (OR 3.43) were independently associated with in-hospital mortality in surgically managed ATAAD patients. CONCLUSIONS: Risk stratification based on the variables collected at admission may help to identify ATAAS patients with high risk of death following cardiac surgery.

RESUMO

Background and objectives: The relationship between cerebral perfusion and new postoperative ischemic stroke in obese patients is not well defined. The aim of this study was to investigate the association between selective bilateral anterograde cerebral perfusion and new postoperative ischemic stroke in obese patients with emergency surgery for acute type A aortic dissection. Materials and methods: A total of 292 patients with emergency surgery for acute type A aortic dissection were included in this study. Patients with hemorrhagic stroke or ischemic stroke with severe neurological dysfunction at admission that were not candidates for surgery; patients who died in the first 48 h after intensive care admission and patients with incomplete medical records were excluded. Results: The mean age was 59.42 ± 10.68 years and the mean Euroscore was 9.12 ± 1.63. Obesity was present in 76.4%, the incidence of new postoperative ischemic stroke was 27.5%, and the postoperative mortality rate was 26.7%. The mean cardiopulmonary bypass time was 206.81 ± 75.48 min, the aortic cross-clamp time was 118.2 ± 46.42 min, and 90% of cases required cerebral perfusion. The mean cerebral perfusion time was 30.8 ± 24.41 min. Obese patients had a higher frequency of in-hospital death (p = 0.009), smoking (p = 0.036), hypertension (p = 0.023), left common carotid artery dissection (p < 0.001), right common carotid artery dissection (p = 0.029), femoral artery cannulation (p = 0.026), aortic root replacement (p = 0.009), aortic valve replacement (p = 0.005) and early reintervention for bleeding (p = 0.004). Using logistic regression, selective bilateral anterograde cerebral perfusion over 40 min in obese patients was independently associated with new postoperative ischemic stroke (OR = 2.35; 95%CI = 1.36-4.86; p = 0.021). Conclusions: A patient-tailored strategy for cerebral perfusion should be considered in obese patients, considering the high atheromatous burden of the supra-aortic vessels in these patients and the potential risk of atheromatous embolization associated with this technique.

RESUMO

Acute type A aortic dissection (ATAAD) is a surgical emergency with a mortality of 1-2% per hour. Since its discovery over 200 years ago, surgical techniques for repairing a dissected aorta have evolved, and with the introduction of hypothermic circulatory arrest and cerebral perfusion, complex techniques for replacing the entire aortic arch were possible. However, postoperative neurological complications contribute significantly to mortality in this group of patients. The aim of this study was to determine the association between different bilateral selective antegrade cerebral perfusion (ACP) times and the incidence of postoperative ischemic stroke in patients with emergency surgery for ATAAD. Patients with documented hemorrhagic or ischemic stroke, clinical signs of stroke or neurological dysfunction prior to surgery, that died on the operating table or within 48 h after surgery, from whom the postoperative neurological status could not be assessed, and with incomplete medical records were excluded from this study. The diagnosis of postoperative stroke was made using head computed tomography imaging (CT) when clinical suspicion was raised by a neurologist in the immediate postoperative period. For selective bilateral antegrade cerebral perfusion, we used two balloon-tipped cannulas inserted under direct vision into the innominate artery and the left common carotid artery. Each cannula is connected to a separate pump with an independent pressure line. Near-infrared spectroscopy was used in all cases for cerebral oxygenation monitoring. The circulatory arrest was initiated after reaching a target core temperature of 25-28 °C. In total, 129 patients were included in this study. The incidence of postoperative ischemic stroke documented on a head CT was 24.8% (31 patients), and postoperative death was 20.9% (27 patients). The most common surgical technique performed was supravalvular ascending aorta and Hemiarch replacement with a Dacron graft in 69.8% (90 patients). The mean cardiopulmonary bypass time was 210 +/- 56.874 min, the mean aortic cross-clamp time was 114.775 +/- 34.602 min, and the mean cerebral perfusion time was 37.837 +/- 18.243 min. Using logistic regression, selective ACP of more than 40 min was independently associated with postoperative ischemic stroke (OR = 3.589; 95%CI = 1.418-9.085; p = 0.007). Considering the high incidence of postoperative stroke in our study population, we concluded that bilateral selective ACP should be used with caution, especially in patients with severely calcified ascending aorta and/or aortic arch and supra-aortic vessels. All efforts should be made to minimize the duration of circulatory arrest when using bilateral selective ACP with a target of less than 30 min, in hypothermia, at a body temperature of 25-28 °C.

RESUMO

Background and Objectives: Postoperative neurological complications (NCs) are an important cause of mortality in patients with acute type A aortic dissection (ATAAD). The aim of the study was to determine the association between intraoperative risk factors and newly developed postoperative NCs in patients after emergency surgery for ATAAD. Materials and Methods: A total of 203 patients requiring emergency surgery were included in the study. Patients with preoperative neurological dysfunction, deceased on the operating table or within the first 48 h after intensive care admission, with uncertain postoperative neurologic status or with incomplete records were excluded. Results: Mean age was 57.61 ± 12.27 years. Hyperlipidemia was the most frequent comorbidity (69%). A bicuspid aortic valve was present in 12.8% of cases, severe acute aortic regurgitation was present in 29.1% of patients, and cardiac tamponade was present in 27.1% of cases. The innominate artery was the most frequently dissected supra-aortic artery in 27.1% of cases. In 65% of cases, the primary entry tear was at the level of the ascending aorta. The incidence of newly developed postoperative NCs was 39.4%. The most common surgical technique performed was supra-coronary ascending aorta and hemiarch replacement, in 53.2% of patients. Using logistic regression, cardiopulmonary bypass time (OR = 1.01; 95% CI = 1.01-1.02; p < 0.001), aortic cross-clamp time over 3 h (OR = 2.71, 95% CI = 1.43-5.14, p = 0.002) and cerebral perfusion time (OR = 1.02; 95% CI = 1.002-1.03; p = 0.027) were independently associated with newly developed postoperative NCs. Conclusions: Based on the results of the study, all efforts should be made to reduce operative times. Using a simple surgical technique, like the supra-coronary ascending aorta and hemiarch technique, whenever possible, and using a simpler technique for cerebral perfusion like unilateral cerebral perfusion via the right axillary artery, could reduce operating times.

RESUMO

BACKGROUND: Aortic coarctation (CoAo) may be discovered only when complicated by acute type A aortic dissection (ATAAD). We present a case with a one-stage repair of this pathologic association and review the relevant literature focusing on the surgical choices. CASE REPORT: A 43-year-old man presented with acute thoracic pain. Computed tomography and echocardiography demonstrated CoAo, ATAAD type II, an ascending aorta aneurysm, and moderate regurgitation of a bicuspid aortic valve. Emergency surgery was performed. A clamshell incision, cardiopulmonary bypass with dual arterial cannulation (axillo-femoral), CoAo repair (by resection-interposition), and supracoronary aorta replacement were performed. Four years later, the patient was healthy and asymptomatic. REVIEW: Thirty surgical cases of ATAAD with CoAo repair after the dissection onset were included. Iatrogenic dissections and formerly repaired CoAo without surgical indication were excluded. RESULTS: The mean patient age was 27.8 ± 12 years; there was a male predominance (76.7%). The patients frequently presented with ascending aorta aneurysm (86.2%), bicuspid aortic valve (69%), and type II dissection (79.3%); dissection never extended below the CoAo. The one-stage treatment (15 patients; 55.5%) included 12 surgical repairs of CoAo (mostly by ascending-to-descending aorta extra-anatomic bypass; 58.3%) and three balloon angioplasties. In patients with uncorrected CoAo at the onset of cardiopulmonary bypass, double arterial perfusion was used in 55.5%. CONCLUSIONS: One-stage repair (hybrid or surgical), double arterial perfusion, and extra-anatomic ascending-to-descending aorta bypass are the most common options for treating ATAAD-CoAo. The clamshell incision provides excellent access for an extended arch procedure and facilitates anatomic isthmus repair.

RESUMO

Pre-procedure mitral regurgitation (MR) is a frequent coexistent finding in patients undergoing transcatheter aortic valve replacement (TAVR), and most of them (up to 55%) experience a significant improvement in MR after the procedure. Although seldom described, mitral valve perforation after TAVR is a potentially serious complication that physicians should be aware of, as moderate or severe MR in TAVR recipients is associated with a high early mortality rate. We herein describe the case of a 65-year-old man presenting with worsening heart failure symptoms 5 months after TAVR due to an intraprocedural anterior mitral leaflet perforation and discuss the diagnostic process and therapeutic course of the case. Furthermore, we draw attention to the essential role of echocardiography in the management of TAVR procedures, taking into account its ability in detecting early complications, and emphasize the value of CT as a main determinant to predict long-term MR improvement after TAVR and to assess the potential candidates for double valve repair with percutaneous techniques.

RESUMO

Ever since it was first described in 1760, acute type A aortic dissection has created difficulties in its management. The recent COVID-19 pandemic revealed that extrapulmonary manifestations of this condition may occur, and recent reports suggested that aortic dissection may be amongst them since it shares a common physiopathology, that is, hyper-inflammatory syndrome. Cardiac surgery with cardiopulmonary bypass in the setting of COVID-19-positive patients carries a high risk of postoperative respiratory failure. While the vast majority accept that management of type A aortic dissection requires urgent surgery and central aortic therapy, there are some reports that advocate for delaying surgery. In this situation, the risk of aortic rupture must be balanced with the possible benefits of delaying urgent surgery. We present a case of acute type A dissection with COVID-19-associated bronchopneumonia successfully managed after delaying surgery for 6 days.

RESUMO

Brachial mycotic pseudoaneurysms (BMPA) are a rare complication of infective endocarditis (IE), but potentially could be a limb-threatening condition. We present the case of a 38-year-old male referred to our department, complaining of the sudden onset of a painful pulsatile mass 5 x 10 cm in the right antecubital fossa that slowly progressed over time. Two years before this, he underwent aortic and mitral valve replacement with mechanical prosthetic valves and tricuspid annuloplasty for IE with methicillin-susceptible Staphylococcus aureus after a six-week course of intravenous antibiotherapy with oxacillin. Clinical examination of the right upper limb revealed a pulsatile and compressible mass with a normal temperature and without other clinical signs of inflammation. Pulse of the axillary artery, brachial and radial arteries were palpable. He was diagnosed by Doppler ultrasonography and digital subtraction angiography with BMPA. Furthermore, transesophageal echocardiography (TEE) revealed normal function of the aortic and mitral prosthetic valve with no signs of prosthetic valve endocarditis and no feature of congestive heart failure. Considering these clinical findings, surgical treatment was planned. He underwent re-section of the brachial pseudoaneurysm and arterial reconstruction. One year after the pseudoaneurysm resection, evolution was excellent. This manuscript presents this rare, uncommon complication after IE and also reviews the available surgical management strategies for this pathology.

RESUMO

Lipomas are the most common type of soft tissue tumors. They mainly are located in subcutaneous tissue in the body, including the heart. The cardiac location of lipomas is rare, mostly asymptomatic, and can cause life-threatening complications by rapid growth. The clinical symptoms, when present, occur in evolution with the growth in size, depending upon the location and degree of invasion in the endocardium. We present the case of a 63-year-old male patient with a large intrapericardial lipoma with an unusual location, originating from the left atrial roof. The initial symptoms of the patient were shortness of breath, dizziness, and mild dyspnea. Transthoracic echocardiography (TTE) was the first line diagnosis method, followed by computed tomography (CT); both showed a large posterior intrapericardial mass. Resection of a 12/8/5 cm lipomatous tumor mass was performed via median sternotomy, under cardiopulmonary bypass (CPB) on the beating heart. Histopathologic examination revealed the presence of diffuse proliferation of large- and medium-sized mature adipocytes consistent with the diagnosis of pericardial lipoma. The patient was discharged at home on the seventh postoperative day, with a marked improvement of his clinical state and effort tolerance. He did not present evidence of recurrence at his 1-year follow up.

RESUMO

Iatrogenic iliac arteriovenous fistula (IAVF) is an extremely rare complication after lumbar discectomy surgery (LDS), with potentially life-threatening consequences. An IAVF results from the close anatomic relation between the iliac vessels and the last lumbar vertebrae and the corresponding discs. We report the case of a 45-year-old woman who developed a large right IAVF 3 years after L4-L5-S1 laminectomy. The arteriovenous fistula (AVF) was successfully treated with an endovascular technique using a WALLSTENT self- expanding stent. The postoperative period was uneventful, and the patient was discharged from the hospital in good general condition on the third postoperative day.

RESUMO

We consider mitral valve disease requiring surgery in a patient with dextrocardia and situs inversus totalis to be an exceptional finding. The transseptal approach for mitral valve surgery in dextrocardia represents a technical challenge owing to its anatomic particulars. We present the case of a 56-year-old female patient who had been diagnosed with situs inversus totalis in childhood and with chronic atrial fibrillation in adulthood and was under oral anticoagulant treatment. She was referred to our hospital for increasing dyspnea and palpitation. Transthoracic echocardiography detected severe mitral regurgitation associated with moderate tricuspid regurgitation, with normal left and right ventricular function. Contrast chest computed tomography (CT) and preoperative abdominal CT showed both dextrocardia and situs inversus totalis, with normal continuity of the inferior vena cava. Biatrial cannulation was performed with the surgeon standing on the right side of the patient, and mitral valve replacement using a transseptal approach was performed with the surgeon standing on the left side of the patient. In this case report, we emphasize the rarity of mitral valve disease in a patient with dextrocardia and the inherent potential difficulty that can appear in this particular anatomic condition.

RESUMO

Superior vena cava collapsibility index (SVC-CI) and stroke volume variation (SVV) have been shown to predict fluid responsiveness. SVC-CI has been validated only with conventional transoesophageal echocardiography (TEE) in the SVC long axis, on the basis of SVC diameter variations, but not in the SVC short axis or by SVC area variations. SVV was not previously tested in vascular surgery patients. Forty consecutive adult patients undergoing open major vascular surgical procedures received 266 intraoperative volume loading tests (VLTs), with 500 ml of gelatine over 10 min. The hSVC-CI was measured using a miniaturized transoesophageal echocardiography probe (hTEE). The SVV and cardiac index (CI) were measured using Vigileo-FloTrac technology. VLTs were considered 'positive' (≥ 11% increase in CI) or 'negative' (< 11% increase in CI). We compared SVV and hSVC-CI measurements in the SVC short axis to predict fluid responsiveness. Areas under the receiver operating characteristic curves for hSVC-CI and SVV were not significantly different (P = 0.56), and both showed good predictivity at values of 0.92 (P < 0.001) and 0.89 (P < 0.001), respectively. The cutoff values for hSVC-CI and SVV were 37% (sensitivity 90%, specificity of 83%) and 15% (sensitivity 78%, specificity of 100%), respectively. Our study validated the value of the SVC-CI measured as area variations in the SVC short axis to predict fluid responsiveness in anesthetized patients. An hTEE probe was used to monitor and measure the hSVC-CI but conventional TEE may also offer this new dynamic parameter. In our cohort of significant preoperative hypovolemic patients undergoing major open vascular surgery, hSVC-CI and SVV cutoff values of 37% and 15%, respectively, predicted fluid responsiveness with good accuracy.

RESUMO

BACKGROUND: Acute decompensated heart failure (ADHF) is the most common presenting phenotype of acute heart failure (AHF). The main goal of this article was to review the contemporary management strategies in these patients and to describe how future clinical trials may address unmet clinical needs. AREAS OF UNCERTAINTY: The current pathophysiologic understanding of AHF is incomplete. The guideline recommendations for the management of ADHF are based only on algorithms provided by expert consensus guided by blood pressure and/or clinical signs of congestion or hypoperfusion. The lack of adequately conducted trials to address the unmet need for evidence therapy in AHF has not yet been surpassed, and at this time, there is no evidence-based strategy for targeted decongestive therapy to improve outcomes. The precise time point for initiation of guideline-directed medical therapies (GDMTs), as respect to moment of decompensation, is also unknown. DATA SOURCES: The available data informing current management of patients with ADHF are based on randomized controlled trials, observational studies, and administrative databases. THERAPEUTIC ADVANCES: A major step-forward in the management of ADHF patients is recognizing congestion, either clinical or hemodynamic, as a major trigger for heart failure (HF) hospitalization and most important target for therapy. However, a strategy based exclusively on congestion is not sufficient, and at present, comprehensive assessment during hospitalization of cardiac and noncardiovascular substrate with identification of potential therapeutic targets represents "the corner-stone" of ADHF management. In the last years, substantial data have emerged to support the continuation of GDMTs during hospitalization for HF decompensation. Recently, several clinical trials raised hypothesis of "moving to the left" concept that argues for very early implementation of GDMTs as potential strategy to improve outcomes. CONCLUSIONS: The management of ADHF is still based on expert consensus documents. Further research is required to identify novel therapeutic targets, to establish the precise time point to initiate GDMTs, and to identify patients at risk of recurrent hospitalization.

RESUMO

BACKGROUND: Cardiogenic shock (CS) is a life-threatening state of tissue hypoperfusion, associated with a very high risk of mortality, despite intensive monitoring and modern treatment modalities. The present review aimed at describing the therapeutic advances in the management of CS. AREAS OF UNCERTAINTY: Many uncertainties about CS management remain in clinical practice, and these relate to the intensity of invasive monitoring, the type and timing of vasoactive therapies, the risk-benefit ratio of mechanical circulatory support (MCS) therapy, and optimal ventilation mode. Furthermore, most of the data are obtained from CS in the setting of acute myocardial infarction (AMI), although for non-AMI-CS patients, there are very few evidences for etiological or MCS therapies. DATA SOURCES: The prospective multicentric acute heart failure registries that specifically presented characteristics of patients with CS, distinct to other phenotypes, were included in the present review. Relevant clinical trials investigating therapeutic strategies in post-AMI-CS patients were added as source information. Several trials investigating vasoactive medications and meta-analysis providing information about benefits and risks of MCS devices were reviewed in this study. THERAPEUTIC ADVANCES: Early revascularization remains the most important intervention for CS in settings of AMI, and in patients with multivessel disease, recent trial data recommend revascularization on a "culprit-lesion-only" strategy. Although diverse types of MCS devices improve hemodynamics and organ perfusion in patients with CS, results from almost all randomized trials incorporating clinical end points were inconclusive. However, development of new algorithms for utilization of MCS devices and progresses in technology showed benefit in selected patients. A major advance in the management of CS is development of concept of regional CS centers based on the level of facilities and expertise. The modern systems of care with CS centers used as hubs integrated with emergency medical systems and other referee hospitals have the potential to improve patient outcomes. CONCLUSIONS: Additional research is needed to establish new triage algorithms and to clarify intensity and timing of pharmacological and mechanical therapies.

RESUMO

Association of elective debranching and endovascular thoracic aortic repair (TEVAR) with aberrant left vertebral artery (AVA) revascularization and supra-aortic left carotid-subclavian bypass in post-traumatic pseudoaneurysm of the distal aortic arch are extremely rare procedures that can minimize unnecessary neurologic complications. The patient was a 42-year-old man, stable, with a post-traumatic transection of the aortic isthmus, with origin of the AVA between the left common carotid artery (LCCA) and left subclavian artery (LSA). Preoperative planning and proper sizing of the stent-grafts were evaluated by means of computed tomography angiography (CT scan) images. The patient underwent a hybrid procedure that included TEVAR with landing zone 2, covering the origin of both the AVA and LSA and concomitant supra-aortic reimplantation of the AVA in the LCCA and left carotid-subclavian bypass combined with both ligation of the AVA and LSA proximally. Postoperative arteriography images confirmed the exclusion of the aneurysm and the patency of all arch vessels, including the AVA. No endoleak was reported.

RESUMO

Patients diagnosed with ocular myasthenia gravis (MG) and mitral valve disease represent a significant perioperative management problem, especially for the anaesthesiologist, due to complex inter-actions between the disease, drugs to treat the disease, and anaesthetic agents, such as neuromuscu-lar blocking agents (NMBAs). This paper describes the successful management of a 31-year-old female with mitral valve stenosis and ocular MG who was diagnosed with MG 4 years prior to the indication for cardiac surgery. Preoperatively, the patient was under treatment with Pyridostigmine and Prednisone. Mitral valve replacement and full thymectomy were performed, under general anaesthesia, using Fentanyl, Sevoflurane and low doses of non-depolarising NMBAs. The postoperative course was uneventful, the patient was extubated at 6 hours postoperatively, in-tensive care unit stay was 48 hours, and the patient was discharged after 6 days without any compli-cations. After 3 months, at the follow-up examination, the patient's ocular symptoms (eyelid ptosis) disappeared.

RESUMO

Since the discovery of penicillin, the incidence of tertiary syphilis dramatically has decreased. However, cases of cardiovascular complications of syphilis still are present. Ascending aortic aneurysms are some of the most devastating complications. Nonetheless, syphilitic aortitis (SA) can appear and should be suspected in patients with syphilis and aortic aneurysm. We report a case of a 57-year-old patient with a large ascending aortic aneurysm with cartilage and rib erosion. The purpose of this article is to discuss the particular surgical aspects of this unusual case.

RESUMO

Coronary artery spasm (CAS) after coronary artery bypass grafting (CABG) is rare, and in time may be fatal for the patient if undiagnosed. The purpose of the present study is to report the case of a patient who survived after experiencing a persistent spasm of all native coronary arteries following successful arterial myocardial revascularization. Furthermore, we aimed to discuss the therapeutic strategies which may prevent the occurrence of a coronary artery spasm in settings of myocardial revascularization, in the context of reviewed specific literature evidences.
