RESUMO

The Intra Aortic Balloon Pumping( IABP) is a circulatory assist device widely used in cardiovascular surgery area. The IABP increases coronary perfusion and (may increase?)intracranial blood flow through diastolic augmentation mechanism and it reduces afterload and myocardial oxygen consumption through systolic unloading mechanism. Safer insertion of the IABP is able to be accomplished with the assistance of radioscopy or a transesophageal echocardiography(TEE). Based on the experience in our institution, we describe the IABP insertion technique with a TEE guide.

RESUMO

BACKGROUND: Training in transesophageal echocardiography (TEE) is based on hands-on training in the operating room, which is time consuming and therefore limits its experience among anesthesiologists. Medical simulations have been successfully used for training of invasive procedures in many areas.This paper compares the difference in effectiveness of teaching the 11 basic TEE views using either e-learning, simulation based training or hands-on training in the operating room in 3 groups of residents. METHODS: We included 51 anesthesia and intensive care residents of all training levels but no prior training in echocardiography in this prospective randomized single-center study.Residents received a tutorial about theoretical knowledge followed by 2 practical study sessions either by e-learning using an online simulator (www.pie.med.utoronto.ca/TEE), with the simulation mannequin (CAE Vimedix Simulator) or in the operating room. Both, a theoretical multiple choice test (0-50 points) and a practical exam test (0-110 points) on the simulation mannequin had to be completed.The primary endpoint was the post-training scores in the practical and theoretical exams after all training sessions. RESULTS: Residents received significantly higher test scores in both practical and theoretical examinations after training with the simulation mannequin (108.41 ±â€Š2.09, 40.6 ±â€Š5.23, n = 17) compared with e-learning (106.88 ±â€Š4.53, 36 ±â€Š4.76, n = 17) or hands-on training (106.82 ±â€Š2.01, 34.94 ±â€Š4.72, n = 17). CONCLUSIONS: Simulation based TEE training provides more effective training than other teaching methods. It is therefore especially suitable for the initial stages of TEE training to acquire psychomotor skills and knowledge of echo-anatomy.

RESUMO

Patients with advanced valvular disease may be at high or prohibitive risk for surgical management. We describe a patient with previous mitral and tricuspid valve repair and recurrent admissions for New York Heart Association Class IV heart failure symptoms due to severe mitral stenosis and severe tricuspid regurgitation. Due to her comorbidities and two previous sternotomies, the patient was at high risk for surgery. We performed a simultaneous transfemoral mitral and tricuspid valve-in-ring implantation. This is the first report of its kind using a Sapien 3 valve (Edwards Lifesciences).

RESUMO

The diagnostic performance of 320-detector cardiac computed tomography (CCT) for the detection of thrombi in the left atrial appendage (LAA), relative to transesophageal echocardiography (TEE) as the gold standard, has not yet been evaluated. A total of 91 consecutive patients who were scheduled to undergo pulmonary vein isolation and underwent TEE and CCT were enrolled in this study. Delayed scanning on CCT was performed following early scanning, at 60 seconds after the start of the contrast injection. The radiation dose was estimated for both scans. The early scans showed a contrast medium filling defect (FD) in the LAA in 27 patients, whereas the delayed scans showed an FD in the LAA in six patients. Of these, five patients were confirmed to have a thrombus in the LAA by TEE. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 100, 74.4, 18.5, 100, and 75.8% for early scanning and 100, 98.8, 83.3, 100, and 98.9% for delayed scanning, respectively. The area under the curve for the detection of a thrombus in the LAA on the delayed scans was significantly larger than that for the detection on the early scans (0.99 versus 0.87, P < 0.001). The estimated median radiation doses for the early and delayed scans were 2.86 and 0.42 mSv, respectively. Addition of delayed scanning to early scanning improved the diagnostic performance for the detection of a thrombus in the LAA and may obviate unnecessary TEE, with minimal additional radiation exposure.

RESUMO

BACKGROUND: Radiofrequency catheter ablation is approved effective therapy for premature ventricular contraction. However, the rare but serious complication such as pseudoaneurysm should be given more attention. It is life-threatening due to the high risk of rupture. Only few cases have been reported in the literature. We herein report a huge acute left ventricular pseudoaneurysm after catheter ablation therapy. CASE PRESENTATION: A 69-year-old man underwent radiofrequency catheter ablation for premature ventricular contraction at a local hospital. The patient developed shock the second day after ablation. A chest computed tomography (CT) scan showed pericardial effusion. Pericardiocentesis was performed, and the puncture fluid was a bloody pericardial effusion. The transthoracic echocardiogram revealed an 9- × 4-cm giant pseudoaneurysm with a cystic structure in the left ventricular inferior wall near the mitral annulus along the left atrium. The pseudoaneurysm was connected to the left ventricular cavity through a 8-mm neck, and the lumen was filled with systolic and diastolic blood flow. The patient underwent three-dimensional transesophageal echocardiography. The pseudoaneurysm and the tract was clearly visible. Emergency surgery was performed to resect the pseudoaneurysm. A bovine pericardial patch was placed on the neck of the pseudoaneurysm. Echocardiographic examination confirmed the absence of cardiac lesions after the operation. CONCLUSIONS: It is rare to see such a large pseudoaneurysm after radiofrequency catheter ablation. Clinicians should be allert to the potential risks to patients in the process of an effective treatment. Echocardiography plays an important role in the prompt diagnosis and prognosis of this disease. Emergency surgery is a better method for treatment of huge pseudoaneurysm.

RESUMO

BACKGROUND: There are no unanimous reports on different layouts and classifications of multi-hole secundum atrial septal defects (MHASD) and subsequent standardized occlusion techniques. The MHASD can be isolated or cribriform with variable inter-defects distance. In this retrospective study, experience-based classification and two approaches-based occlusion results are presented. METHODS: We retrospectively collected and analyzed data of 150 MHASD patients from 1320 patients who underwent atrial septal defect occlusion in our institute. The MHASD patients were categorized into 4 types; type A, B, C and D and occluded under exclusive transesophageal echocardiographic guidance. According to different types, 122 patients were occluded using peratrial approach and 28 patients via percutaneous approach. In type A, single device implantation is performed to occlude the large hole and squeeze the small one. For type B single or double-device deployment was performed depending on an inter-defects distance. In type C and D, a patent foramen-ovale (PF) device was selectively positioned to the central defect to occlude the central defect and cover the peripheral ones. In peratrial approach, 8 patients underwent inter-defects septal puncture technique to achieve single-device occlusion. The intracardiac manipulation time, procedural time, double device deployment, redeployment rate, residual shunt, and proportions were analyzed between (and within peratrial technique) two techniques. RESULTS: Successful occlusion was achieved in all 150 patients. Single device occlusion was applied in 78/84 type A and 22/37 type B patients (p < 0.05). Double device occlusion was more applicable to type B than A patients (p < 0.01). Sixteen of 21 type C and all type D patients used PF device for a satisfactory occlusion. Redeployment of the device occurred frequently in type B patients than A (p < 0.01). The intracardiac manipulation time and procedural time were shorter in type A than B (p < 0.05). The intracardiac manipulation time was also shortened in type A peratrial than type A percutaneous group (p < 0.05). Complete occlusion rate for all patients at discharge was 70% and rose to 82% at 1 year follow up. CONCLUSIONS: The diverse layouts and classification of MHASDs can help to choose different techniques and proper devices of different kinds to achieve better occlusion results.

RESUMO

Mitral valve aneurysm is a rare abnormality whose pathophysiology is poorly understood. It is defined as a bulge of the mitral valve leaflet toward the left atrium. Aneurysm in the posterior leaflet is exceptional. We report the case of a 26-year old man, who had been followed up for rheumatic aortic regurgitation for 4-years, hospitalized for febrile syndrome associated with episodes of left heart failure. Transthoracic echocardiographic examination (TTE) and transesophageal echocardiography (TEE) showed aortic valve vegetations with wide aneurysm of the small mitral valve associated with severe mitral valve regurgitation. The patient underwent mitral and aortic valve replacement with simple postoperative outcome. Clinical suspicion associated with suitable preoperative imaging and early surgical treatment are essential to recognize and treat this rare complication of infectious endocard.

RESUMO

BACKGROUND: Atrial septal defect (ASD) is a congenital cardiac defect often diagnosed in adult patients. Mitral regurgitation (MR) observed in ASD patients mostly improves after ASD closure. However, a subset of adult ASD patients present new-onset MR or aggravation of preexisting MR after ASD closure. Intraoperative MR aggravation after surgical ASD closure is a rare occurrence which has not been reported in the literature to date. CASE PRESENTATION: A 54-year-old woman was referred to our center due to large secundum ASD with a diameter of 17 mm which was incidentally detected on pre-operative echocardiography at a local clinic. Surgical repair of ASD under mini-thoracotomy was performed. After completion of the operation, intra-operative transesophageal echocardiography showed newly developed Grade II MR which subsequently deteriorated to severe level on postoperative day 3. Because the patient was asymptomatic, we decided to observe closely and treat conservatively with diuretics. Thereafter, echocardiography was evaluated on postoperative day 10 and MR disappeared to trivial level. CONCLUSIONS: Intraoperative MR aggravation is a rare complication following ASD closure. The possibility of MR aggravation should be evaluated in all ASD patients prior to surgery. This case highlights the importance of mitral leaflet examination after ASD closure for early detection of MR.

RESUMO

Chronic thromboembolic pulmonary hypertension (CTEPH) is characterized by chronic thrombi in the pulmonary arteries, causing pulmonary hypertension and right heart failure. Early and accurate diagnosis are essential for successful treatment but are often difficult because clinical signs and symptoms can be nonspecific and risk factors, such as history of venous thromboembolism, may not always be present. Here, we report a case involving a 76-year-old woman who demonstrated paradoxical cerebral embolism as the initial manifestation of CTEPH. She developed right hemiplegia without dyspnea or edema. Brain magnetic resonance imaging revealed multiple fresh infarctions, while transesophageal echocardiography revealed a patent foramen ovale. Based on these findings, she was diagnosed as having paradoxical cerebral embolism. During the search for the embolic source, right heart catheterization showed significant pulmonary hypertension and pulmonary angiography revealed chronic thrombi in the peripheral pulmonary arteries, consistent with a diagnosis of CTEPH. To our knowledge, this is the first case of CTEPH to be diagnosed with the onset of paradoxical cerebral embolism. Because CTEPH is the only potentially curable form of pulmonary hypertension, clinicians should consider paradoxical cerebral embolism as a possible initial manifestation of CTEPH.

RESUMO

A 92-year-old man with acute heart failure due to severe aortic stenosis underwent transcatheter aortic valve implantation (TAVI). Computed tomography demonstrated severe stenosis of the right common iliac artery, occlusion of the left external iliac artery, and stenosis of the left subclavian artery. Severe calcification was observed in the sinotubular junction, which was considered a risk factor for aortic dissection with transapical TAVI using a balloon-expanding bioprosthetic valve. Therefore, transaortic (TAo) access was the only option for this high-risk surgical patient. As the maximum distance from the aortic valve annulus to the sheath insertion point was less than 60 mm, TAVI was performed transaortically using a vascular graft that extended this distance, in order to avoid sheath dislocation. Our experience demonstrates that vascular graft application is a viable option in patients with an inadequate distance between the aortic valve annulus and the puncture site in TAo-TAVI.

RESUMO

Right to left (R-L) shunts resulting in cyanosis or systemic embolization occur after the Fontan procedure. The primary modality of diagnosing these is angiography. Successful delineation of these shunts in Fontan patients using selective saline contrast transesophageal echocardiography (SCTEE) may allow for reduced radiation and contrast exposure. We hypothesized that SCTEE could accurately determine the presence, type, and semiquantitative shunt size of R-L shunts in Fontan patients. SCTEE was performed in Fontan patients undergoing angiography for clinical indications. Injections were performed in six sites: mid-Fontan, right and left pulmonary arteries, superior and inferior vena cavae, and innominate vein. R-L shunt size was subjectively graded as 0 = absent, 1 = small, and 2 = medium or large based on echo contrast density in the left atrium. SCTEE was compared to angiography. 33 patients with Fontan were studied with median age 15 years, median weight 50.1 kg, and median O2 saturation of 90% in the R-L shunt group and 95% in the no R-L shunt group. R-L shunt types included intracardiac shunts (ICS), veno-venous collaterals (VVCs), arteriovenous malformations (AVMs), and their combinations. SCTEE versus angiography results were the same for the presence, type, and size of R-L shunts in 79% (26/33). SCTEE identified shunts in 88% (29/33). Angiography identified shunts in 85% (28/33). Neither method missed any medium or large R-L shunts. SCTEE and angiography had similar accuracy. SCTEE accurately detected the presence, type, and size of R-L shunts in most Fontan patients in this study. This can be used to guide targeted angiography, reducing radiation exposure and contrast load.

RESUMO

BACKGROUND: Infective endocarditis (IE) caused by gram-negative bacilli is rare. However, the incidence of this severe infection is rising because of the increasing number of persons at risk, such as patients with immunosuppression or with cardiac implantable devices and prosthetic valves. The diagnosis of IE is often difficult, particularly when microorganisms such as Pseudomonas aeruginosa, which rarely cause this infection, are involved. One of the mainstays for the diagnosis of IE are persistently positive blood cultures with the same bacteria, while polymicrobial bacteremia usually points to another cause, e.g. an abscess. The antimicrobial resistance profile of some P. aeruginosa strains may change, falsely suggesting an infection with several strains, thus further increasing the diagnostic difficulties. CASE PRESENTATION: A 66-year old male patient who had a transcatheter aortic valve implantation (TAVI) one year previously developed fever seven days after an elective inguinal hernia repair. During the following four weeks, P. aeruginosa with different antibiotic resistance profiles was repeatedly isolated from blood cultures. Repeated trans-esophageal echocardiograms (TEE) were negative and an infection by different P. aeruginosa strains was suspected. Extensive diagnostic workup for an infectious focus was performed with no results. Finally, an oscillating mass on the aortic valve was detected by TEE five weeks after the initial positive blood cultures. P. aeruginosa endocarditis was confirmed by culture of the surgically removed valve. Whole genome sequencing of the last two P. aeruginosa isolates (valve and blood culture) revealed identical strains, with genome mutations for AmpR, AmpD and OprD. CONCLUSIONS: The diagnosis of prosthetic valve endocarditis is particularly difficult for several reasons. The modified Duke criteria have a lower sensitivity for patients with prosthetic valve endocarditis and the infection may be caused by "unusual" pathogens such as P. aeruginosa. Patients with repeatedly positive blood cultures should make clinicians suspicious for endocarditis even if imaging studies are negative and if isolated pathogens are "unusual". Repeatedly positive blood cultures for P. aeruginosa should be considered as "persistent bacteremia" (suspicious for IE) even in the presence of different antibiotic susceptibility patterns, since P. aeruginosa might rapidly activate or deactivate resistance mechanisms depending on antibiotic exposition.

RESUMO

Intraoperative evaluation of mitral regurgitation is a complex undertaking. Bileaflet prolapse/flail can result in divergent mitral regurgitation jets with a characteristic "crossed swords sign" appearance. We present a case of divergent mitral regurgitation jets that were detected intraoperatively and evaluated using 3-dimensional imaging. The accurate assessment of eccentric mitral regurgitation jets, especially bilateral eccentric mitral regurgitation jets, is challenging before surgical repair. Intraoperative 3-dimensional transesophageal echocardiography with and without color-flow Doppler can significantly improve the localization of the anatomical lesion.

RESUMO

AIMS: Device surveillance after left atrial appendage (LAA) closure (LAAC) is important to assess device positioning, peri-device leak (PDL) and device-related thrombus (DRT). There are limited data on the role of cardiac CT angiography (CCTA) after LAAC. We therefore sought to compare CCTA to transoesophageal echocardiography (TEE) in patients who successfully underwent LAAC. METHODS AND RESULTS: We report our consecutive series of non-valvular atrial fibrillation patients who underwent LAAC and had CCTA and TEE post LAAC. Prospective cardiac-gated CCTA was performed with the Toshiba 320-detector or Siemens second-generation 128-slice dual-source scanner, and post-processing was performed with IMPAX 3D reformats. Glomerular filtration rate <30 mL/min/1.73 m² was an exclusion for CCTA. Device positioning, PDL or fabric leak, ratio of left atrial (LA) to LAA linear attenuation coefficient, and DRT were analysed. One hundred and two patients underwent LAAC (79 WATCHMAN, 17 Amulet, 6 ACP). Mean age was 76.4±7.5 years, CHADS2 score 3.0±1.3, and CHADS-VASc score 4.6±1.6. CCTA was performed at a mean of 105.2±54.8 days, and TEE at a mean of 124.9±100.3 days post LAAC. LAA patency was observed in 52/100 (52%), with 45 (86.5%) via PDL and seven (13.5%) through fabric leak. Linear attenuation coefficient <100 HU and LA:LAA ratio <0.25 were seen in occluded devices. PDL was only observed in 35/102 (34.3%) on TEE. Mean device compression was greater with sealed devices (11.3±4.3% versus 8.2±4.0%, p<0.001). There was only one DRT, which was observed on both TEE and CCTA. CONCLUSIONS: CCTA is a suitable alternative to TEE for device surveillance post LAAC. CCTA was more sensitive than TEE for assessing PDL and can delineate the cause of residual LAA contrast patency.
