RESUMO

Coronary artery fistulas draining into the left ventricle is a rare finding. They can be associated with other congenital cardiac anomalies like ventricular septal defect or tetralogy of Fallot. While most of them are asymptomatic, they can lead to severe cardiac complications like infective endocarditis, heart failure, or myocardial ischemia. Symptomatic coronary artery fistulas can be managed surgically or percutaneously. We present a case of a 61-year-old male patient with both left anterior descending artery and right coronary artery fistulas draining into the left ventricle associated with ascending aorta and root aneurysm. Preoperative assessment for myocardial ischemia and the size and location of the fistulas was performed. The echocardiography stress test was negative. Surgery consisted of replacement of the ascending aorta and reconstruction of the noncoronary sinus with a Dacron patch with aortic valve preservation and no intervention for the coronary artery fistulas. The surgical strategy was adapted for cardioplegia administration to compensate for the volume of coronary blood drained into the left ventricle and for better protection of the distal myocardium.

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

BACKGROUND: Coronary artery bypass grafting has evolved from all venous grafts to bilateral mammary artery (BIMA) grafting. This was possible due to the long-term patency of the left and right internal mammary demonstrated in angiography studies compared to venous grafts. However, despite higher survival rates when using bilateral mammary arteries, multiple studies report a higher rate of surgical site infections, most notably deep sternal wound infections, a so-called "never event". METHODS: We designed a prospective study between 1 January 2022 and 31 December 2022 and included all patients proposed for total arterial myocardial revascularization in order to investigate the rate of surgical site infections (SSI). Chest closure in all patients was performed using a three-step protocol. The first step refers to sternal closure. If the patient's BMI is below 35 kg/m2, sternal closure is achieved using the "butterfly" technique with standard steel wires. If the patient's BMI exceeds 35 kg/m2, we use nitinol clips or hybrid wire cable ties according to the surgeon's preference for sternal closure. The main advantages of these systems are a larger implant-to-bone contact with a reduced risk of bone fracture. The second step refers to presternal fat closure with two resorbable monofilament sutures in a way that the edges of the skin perfectly align at the end. The third step is skin closure combined with negative pressure wound therapy. RESULTS: This system was applied to 217 patients. A total of 197 patients had bilateral mammary artery grafts. We report only 13 (5.9%) superficial SSI and only one (0.46%) deep SSI. The preoperative risk of major wound infection was 3.9 +/- 2.7. Bilateral mammary artery grafting was not associated with surgical site infection in a univariate analysis. CONCLUSIONS: We believe this strategy of sternal wound closure can reduce the incidence of deep surgical site infection when two mammary arteries are used in coronary artery bypass surgery.

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

Left ventricular pseudoaneurysm is a rare disease; it is defined as a ventricular rupture contained by epicardium, pericardial adhesions, or both. It most frequently occurs as a complication of acute myocardial infarction. Surgical treatment is recommended for pseudoaneurysms that are large or symptomatic and for those discovered less than 3 months after myocardial infarction. We report our experience with 2 patients who had left ventricular pseudoaneurysms discovered less than a week after inferior myocardial infarction. Both patients were middle-aged men with right coronary occlusion in whom the diagnoses were established by echocardiography during the first week after infarction. Because both patients were clinically stable, we opted to defer surgery until scarring could facilitate correction; this decision was based on a review of the literature showing that in-hospital mortality is higher with early surgery. The patients were monitored closely in the intensive care unit and were prescribed ß-blockers and vasodilators. Both patients underwent left ventricular patch reconstruction with exclusion of the pseudoaneurysm and posterior septum; both received moderate inotropic support and prophylactic intra-aortic balloon pump assistance. Their postoperative courses were uneventful. In 5 prior reports describing 45 patients (13 with acute pseudoaneurysm [≤2 wk after infarction] and 32 with nonacute pseudoaneurysm), in-hospital mortality was 61.5% for patients in the acute group and 15.6% for the nonacute group (P = .0066). We recommend that clinicians consider deferring surgery for patients with stable acute left ventricular pseudoaneurysm to reduce the risks associated with early repair.

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

INTRODUCTION AND IMPORTANCE: Triple-valve replacement in active infective endocarditis has rarely been reported. This paper is the first report of a triple-valve replacement performed in endocarditis with septic shock and the first presentation of multivalvular endocarditis due to Rhizobium radiobacter. CASE PRESENTATION: A 26-year-old patient with a neglected ventricular septal defect referred to us in septic shock, with multiple organ failure, severe biventricular dysfunction, and pulmonary hypertension, due to Rhizobium radiobacter infective endocarditis affecting the aortic, tricuspid and pulmonary valves. Initially, he was deemed unfit for surgery. However, after clinical stabilization, triple-valve replacement, aortic annular abscess repair, membranous septum aneurysm resection, and ventricular septal defect patch closure were performed. The postoperative evolution was good; both ventricles showed functional recovery after six months. CLINICAL DISCUSSION: Although surgery provides the best chances of survival in endocarditis with septic shock, reportedly, most cases are considered inoperable. Clinical stabilization under intensive care using specific therapies to manage septic shock, myocardial dysfunction, and pulmonary hypertension was crucial for surgery success. Custodiol® cardioplegia, and replacement of the right-sided valves using a beating-heart technique were used to reduce the myocardial ischemic time. CONCLUSION: Rhizobium radiobacter, an opportunistic gram-negative bacterium, potentially may cause multiple valve endocarditis. Patients with endocarditis and septic shock initially considered inoperable can still benefit from surgery after tenacious intensive care (cytokine hemoadsorption and levosimendan are helpful in this process). In complex multivalvular procedures, a beating heart technique to replace the right-sided valves should be considered to minimize the duration of myocardial ischemia.

RESUMO

ABSTRACT Introduction: Functional tricuspid regurgitation (TR) is known to complicate adult atrial septal defect (ASD), but its management is still under debate. We reviewed our experience in ASD surgery, focusing on associated functional TR and its treatment. Methods: This retrospective study (2005-2019) included 206 consecutive adult ASD surgical cases without associated valve pathology, except functional TR. Variables were statistically compared on TR classes and surgery-defined groups. Results: Mean age of the patients was 40.3±13 years; 19.9% had sinus venosus syndrome. TR severity was directly related to age, pulmonary systolic pressure, right ventricular and tricuspid annulus diameters, and heart failure class. TR ≥ 2 was found in 134 (65%) patients, while TR ≥ 3 in 56 (27.2%) patients. Tricuspid surgery was associated to shunt closure in 66 (32%) patients, almost all through valve repair; indication was directly related to age, right ventricular and tricuspid annulus diameters, and heart failure class ≥ 3. Tricuspid surgery was more efficient than isolated shunt closure in decreasing TR (79±23% vs. 36±26%; P=1.8 E-18). Device closure availability (last four years of the study) was associated with 1/3 reduction of surgical cases but increased the share of cases with TR>2 (> 51% vs. < 31%; P<0.05). Conclusion: In the era of device closure, surgery for adult ASD is less frequent, but the share of significant TR cases is in net increase. To avoid long-term postoperative TR, we plead for valve repair in all patients with severe TR and for considering repair in moderate TR at risk of persistence.

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

Background and objective Myxomas are the most common cardiac tumors. This study aimed to analyze the possible risk factors associated with late mortality in this group of patients and assess long-term survival. Methods A retrospective study was conducted among patients who underwent myxomas resection between January 2008 and July 2019 in our service. The patients' preoperative, intraoperative, and postoperative data were analyzed. Multivariate logistic regression was performed to identify predictors of mortality at five years. The Kaplan-Meier curve and Cox proportion-adjusted survival curves were used to assess mortality at five and 10 years. Results A total of 108 patients with cardiac myxomas were identified. All cardiac tumors resected were confirmed as myxomas on histopathological examination. Ninety-six patients presented with left-side myxomas (94 left-atria and two left-ventricle) and 12 with right-side myxomas (11 right-atria, one right-ventricle); 78 of the tumors were capsulated, and 30 were sessile-papillary. The mean dimensions were 37 ±6.1 mm on the left side and 41 ±6.7 mm on the right side. Surgical excision was successful in all cases, with 25% requiring interatrial septum patch repair. Recurrence occurred in 2.77% of the patients. Multivariate logistic regression showed chronic kidney disease (CKD) (OR: 7.96, 95% CI: 1.469-43.125, p=0,016) to be an independent predictor for five-year mortality. The mean follow-up period was 7.13 ±2.965 years, and the Kaplan-Meier curve cumulative proportion survival of patients at five years and 10 years were 100% and 88.8%, respectively. There was no statistically significant difference in late-term survival between patients with and without CKD in the Cox proportion-adjusted survival curve (p=0.275). Conclusions Patients with myxomas have a good long-term prognosis following surgical resection. The multivariate logistic regression showed CKD to be an independent predictor of five-year mortality.

RESUMO

Cardiac papillary fibroelastoma (CPF) is a benign tumor of endocardial origin, most frequently solitary, which commonly affects the aortic valve. We report the case of a 62-year-old woman with 10 separate tumors that developed on the mitral, tricuspid, and pulmonary cusps; atrioventricular valve chordae; and left ventricular endocardium. Surgical treatment included valve-sparing resection of the pulmonary cusp tumors and bioprosthetic replacement of the mitral and tricuspid valves, which exhibited extensive tumor invasion. The postoperative course was unremarkable. The high number of CPFs and triple-valve tumor involvement are both exceptional. CPF should be considered whenever multiple cardiac masses are discovered.

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

Despite the development of imagistic methods, the differential diagnosis of a right atrial mass may be difficult to be established, the most common pathologies which should be taken in consideration being represented by thrombus, tumors, prominent crista terminalis, or vegetation of infectious endocarditis. In this study, we present the case of a 63-year-old man with chronic kidney disease, in hemodialysis (HD) with a silicone central venous catheter (CVC) with the incidental transthoracic echocardiography (transthoracic echocardiogram, TTE) finding of a tumoral mass of 35x26 mm in the right atrium (RA), not related with the catheter, which was diagnosed as right atrial myxoma and underwent surgical excision. After reviewing the histopathology probe, the diagnosis of right atrial thrombus was confirmed. In conclusion, differentiating intracardiac right atrial masses (RAMs) could may prove challenging. In our patient, clinical presentation and the preoperative investigations could not differentiate the right atrial thrombus from a myxoma, and only the postoperative histopathology diagnosis was able to guide correct diagnosis.

RESUMO

Paragangliomas are extremely rare neuroendocrine tumors. We report a case of a 44-year-old man with hypertension who presented a tumoral mass located retroperitoneally at the aortic bifurcation which included both the common iliac arteries and the posterior left iliac vein, who experienced an unpredictable intraoperative cardiac arrest with electromechanical dissociation at 5 min after laparotomy. After successful resuscitation and hemodynamic stability, the lesion was fully excised. In the course of tumor manipulation, the patient developed a major hypertensive crisis with peak systolic blood pressure over 280 mmHg. Pathologic examination revealed the presence of diffuse proliferation of large and medium-sized mature adipocytes consistent with paraganglioma diagnosis. The patient was discharged at home on the seventh postoperative day. He did not present evidence of recurrence at the one-year follow-up. In conclusion, paragangliomas can require particular management due to their location but also due to their capacity to discharge substances which might induce life-threatening intraoperative complications.

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

BACKGROUND/AIM: Cardiac papillary fibroelastomas (CPF) are benign tumors, frequently asymptomatic, characterized by a mobile pedunculated mass that arises from the endocardium. When CPF is located in the left ventricle, it may protrude into the left ventricular outflow tract and affect hemodynamics. They are highly thrombogenic, and can also cause some life-threatening events such as cerebral and peripheral embolization. CASE REPORT: We herein report a case of a 74-year-old female admitted to our center with palpitations and dyspnea on exertion. Her past medical history revealed that she had had a transient ischemic attack 7 months before presentation. Echocardiography and cardiac magnetic resonance imaging revealed an intracardiac mass anchored in the anteroapical interventricular septum without interference with aortic or mitral valve functionality. Surgical resection of the left ventricular mass was performed through the left apical ventriculotomy approach. Histopathological examination of the tumor was suggestive of papillary fibroelastoma. The postoperative course was uneventful. The patient was discharged home on the eighth postoperative day, with no recurrence at 6 months. CONCLUSION: Although left ventricular papillary fibroelastomas are benign tumors, they carry a high risk for embolic complications and therefore surgery should be proposed, the transapical approach being a safe and effective method.

RESUMO

Degenerative aortic valve (AV) disease is the most frequent valvular heart disease slowly progressing to severe aortic stenosis (AS) which usually requires aortic valve replacement. Another frequent condition, especially among elderly people, is cardiac amyloidosis (CA), particularly the wild-type transthyretin cardiac amyloidosis (ATTRwt). Since both of these diseases are considered a marker of ageing, there is a significant proportion of elderly patients who associate both severe AS and CA. Recent studies reported a high prevalence of both severe AS and CA (AS-CA) in elderly patients referred for TAVR of 13-16%, carrying a worse prognosis. The present case illustrates the diagnostic algorithm and the management of ATTRwt CA in an elderly patient with severe paradoxical low-flow low-gradient AS, accompanied by a review of the current literature about the red flags which help identifying CA in patients with severe AS, as well as the prognosis and management of these disease association.

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.
