A 79-year-old man had an out-of-hospital acute ST-segment-elevation myocardial infarction with cardiac arrest. Cardiopulmonary resuscitation performed by a bystander resulted in traumatic hemopericardium. We discuss the patient''s case, highlight the challenges of managing simultaneously life-threatening thrombosis and hemorrhage, and present our conclusions regarding the patient''s eventual death. 相似文献

Left ventricular hypertrophy in aortic stenosis is considered a compensatory response for the maintenance of systolic function but a risk factor for cardiac morbidity and death. We investigated the degree of left ventricular mass regression after implantation of the sutureless Medtronic 3f Enable® Aortic Bioprosthesis.We studied 19 patients who, from May 2010 through July 2011, underwent isolated aortic valve replacement with the 3f Enable bioprosthetic valve, with clinical and echocardiographic follow-up at 6 months. The mean age was 77.1 ± 5.1 years (range, 68–86 yr); 14 patients were women (73.7%); and the mean logistic EuroSCORE was 15.4% ± 11.8%. Echocardiography was performed preoperatively, at discharge, and at 6 months'' follow-up. The left ventricular mass was calculated by means of the Devereux formula and indexed to body surface area.The left ventricular mass index decreased from 146.1 ± 47.6 g/m2 at baseline to 118.1 ± 39.8 g/m2 at follow-up (P=0.003). The left ventricular ejection fraction did not change significantly. The mean transaortic gradient decreased from 57.3 ± 14.2 mmHg at baseline to 12.3 ± 4.6 mmHg at discharge and 12.2 ± 5.3 mmHg at follow-up (P <0.001), and these decreases were accompanied by substantial clinical improvement. No moderate or severe paravalvular leakage was present at discharge or at follow-up.In isolated aortic stenosis, aortic valve replacement with the 3f Enable bioprosthesis results in significant regression of left ventricular mass at 6 months'' follow-up. However, this regression needs to be verified by long-term echocardiographic follow-up. 相似文献

One difficulty with external repair of left ventricular rupture after mitral valve replacement is collateral bleeding in friable myocardium adjacent to the rupture. The bleeding is caused by tension on the closing sutures, whether or not pledgets have been used.We report the case of a 69-year-old woman who underwent an uneventful mitral valve replacement. After cardiopulmonary bypass was terminated, brisk bleeding started from high in the posterior left ventricular wall, typical of a type III defect. We undertook external repair, placing a plug of Teflon felt into the cavity of the rupture and sandwiching it into place with pledgeted mattress and figure-of-8 sutures. The space occupied by the plug decreased the distance needed to obliterate the defect and thereby reduced the tension on the sutures necessary to achieve hemostasis. This simple technique enabled closure of the defect and avoided collateral tears that would have compromised an otherwise successful repair. Two years postoperatively, the patient had normal mitral valve function and no left ventricular aneurysm. In addition to reporting the patient''s case, we review the types of left ventricular rupture that can occur during mitral valve replacement and discuss the various repair options. 相似文献

Left ventricular aneurysm, which can impair systolic function, has a reported incidence of 10% to 35% in patients after myocardial infarction. In a 58-year-old woman who had a history of myocardial infarction, we excised a large left ventricular aneurysm and restored left ventricular geometry with use of a bovine pericardial patch. The aneurysm''s characteristics and the patient''s preoperative left ventricular ejection fraction of 0.25 had indicated surgical intervention. The patient had an uneventful postoperative course, and her left ventricular ejection fraction was 0.50 to 0.55 on the 4th postoperative day. This case illustrates the value of surgical treatment for patients who have a debilitating left ventricular aneurysm. 相似文献

Transesophageal echocardiography continues to have a central role in the diagnosis of infective endocarditis and its sequelae. Recent technological advances offer the option of 3-dimensional imaging in the evaluation of patients with infective endocarditis. We present an illustrative case and review the literature regarding the potential advantages and limitations of 3-dimensional transesophageal echocardiography in the diagnosis of complicated infective endocarditis.A 51-year-old man, an intravenous drug user who had undergone bioprosthetic aortic valve replacement 5 months earlier, presented with prosthetic valve endocarditis. Preoperative transesophageal echocardiography with 3D rendition revealed a large abscess involving the mitral aortic intervalvular fibrosa, together with a mycotic aneurysm that had ruptured into the left atrium, resulting in a left ventricle-to-left atrium fistula. Three-dimensional transesophageal echocardiography enabled superior preoperative anatomic delineation and surgical planning. We conclude that 3-dimensional transesophageal echocardiography can be a useful adjunct to traditional 2-dimensional transesophageal echocardiography as a tool in the diagnosis of infective endocarditis. 相似文献

Aortic insufficiency with recirculation can be difficult to diagnose echocardiographically in patients who have continuous-flow left ventricular assist devices. Transthoracic and transesophageal echocardiography can underestimate its severity; moreover, transesophageal echocardiography necessitates general anesthesia. We report the case of a 58-year-old man with obesity and end-stage nonischemic cardiomyopathy who, after 3 months of support with a continuous-flow left ventricular assist device, underwent intracardiac echocardiography to evaluate complications potentially associated with the device. The findings ruled out aortic insufficiency, preventing an unnecessary valvular intervention. 相似文献

Post-myocardial infarction ventricular septal defect is a devastating complication of ST-elevation myocardial infarction. Although surgical intervention is considered the gold standard for treatment, it carries high morbidity and mortality rates. We present 2 cases that illustrate the application of percutaneous closure of a post-myocardial infarction ventricular septal defect: the first in a patient who had undergone prior surgical closure and then developed a new shunt, and the second as a bridge to definitive surgery in a critically ill patient. 相似文献

Pulmonary tumor embolization from renal cell carcinoma is associated with severe cardiopulmonary morbidity and high perioperative mortality rates. We report the case of a 71-year-old woman who presented with right-sided abdominal pain. Magnetic resonance images revealed a mass originating from the upper pole of the right kidney and extending into the infrahepatic portion of the inferior vena cava. Transesophageal echocardiography was continuously used to monitor the mass during intended radical nephrectomy and tumor resection. When the right kidney was mobilized, intracaval thrombus detached and migrated to the patient''s right atrium, causing severe hemodynamic instability. After emergent sternotomy and during the initiation of cardiopulmonary bypass, the mass was no longer echocardiographically detectable in the heart; it was soon removed completely from the left pulmonary artery. The mass was a renal cell carcinoma.We recommend the use of transesophageal echocardiography as an efficient diagnostic tool in the early detection of pulmonary tumor embolization during the resection of renal cell carcinoma that involves the inferior vena cava. 相似文献

Background: The mechanics of the complex left ventricular (LV) myocardial fiber architecture may accurately be assessed by speckle tracking echocardiography (STE). The role of STE to assess LV mechanical dysfunction in the setting of ST segment elevation myocardial infarction (AMI) is still poorly studied. Patients and Methods: 29 consecutive patients (55 ± 13 years) presenting with AMI underwent STE within 72 hours of admission. Reperfusion was achieved with thrombolysis in 15 patients and with primary percutaneous coronary intervention in 14. LV rotational and torsion data were registered during peak systole. Standard Doppler data included LV ejection fraction (EF), mitral inflow deceleration time (DT), and conventional E/A ratio. E/E' ratio (mitral inflow E velocity/tissue Doppler E velocity) was calculated as a marker of LV filling pressure. Twelve subjects with clinically indicated but negative dobutamine stress echocardiogram served as Controls. Results: Peak systolic torsion was not only significantly lower in AMI compared with Controls (13.3 ± 7.6 vs. 21.8 ± 6.1; P < 0.01), it was also lower in subjects with LVEF <40% (5.0 ± 2.9) compared with those who had LVEF >40% (10.6 ± 6.6; P < 0.02). Torsion had a modest but significantly positive linear relation (R = 0.6; P < 0.05) with DT, not with E/E' or LVEF. Conclusion: LV systolic torsion is decreased in AMI and more markedly decreased in patients with LVEF <40%. The most significant linear relationship between DT and torsion may possibly indicate that the LV mechanical dysfunction is also associated with altered filling dynamics.

Bariatric surgery helps many morbidly obese patients lose substantial weight. However, few data exist on its long-term safety and effectiveness in patients who also have continuous-flow left ventricular assist devices and in whom heart transplantation is contemplated. We retrospectively identified patients at our institution who had undergone ventricular assist device implantation and subsequent laparoscopic sleeve gastrectomy from June 2015 through September 2017, and we evaluated their baseline demographic data, preoperative characteristics, and postoperative outcomes.Four patients (3 men), ranging in age from 32 to 44 years and in body mass index from 40 to 57, underwent sleeve gastrectomy from 858 to 1,849 days after left ventricular assist device implantation to treat nonischemic cardiomyopathy. All had multiple comorbidities.At a median follow-up duration of 42 months (range, 24–47 mo), median body mass index decreased to 31.9 (range, 28.3–44.3) at maximal weight loss, with a median percentage of excess body mass index lost of 72.5% (range, 38.7%–87.4%). After achieving target weight, one patient was listed for heart transplantation, another awaited listing, one was kept on destination therapy because of positive drug screens, and one regained weight and remained ineligible.On long-term follow-up, laparoscopic sleeve gastrectomy appears to be safe and feasible for morbidly obese patients with ventricular assist devices who must lose weight for transplantation consideration. Additional studies are warranted to evaluate this weight-loss strategy after transplantation and immunosuppression. 相似文献

Cardiac papillary fibroelastoma is a rare, benign tumor, arising predominantly from cardiac valves. This tumor can cause a variety of symptoms due to thromboembolism. We describe our single-center surgical experience with papillary fibroelastoma of the aortic valve.From April 2004 through June 2013, 6,530 patients underwent cardiac surgery. Of those, 6,098 patients were included in the final analysis. Twenty-one patients (0.34%) underwent surgical resection of 30 papillary fibroelastomas of the aortic valve.Most patients (67%) were incidentally diagnosed to have cardiac papillary fibroelastoma. The usual symptom was cerebral infarction (in 5 of 7 symptomatic patients). A rare presentation of papillary fibroelastoma in one patient was cardiac arrest caused by left main coronary artery ostial obstruction. Tumor size was not related to patient age (Pearson correlation coefficient, 0.34; P=0.13). Neither the number of tumors (1.43 ± 0.72 vs 1.43 ± 0.62) nor tumor size (8.14 ± 2.42 vs 8.07 ± 3.31 mm) was significantly different between symptomatic and asymptomatic patients. All lesions were resected by means of the simple shave technique. There were no operative or 30-day deaths. Follow-up echocardiograms showed no tumor recurrence (mean follow-up duration, 17 ± 14 mo).We identified no significant relationship among tumor size, number of tumors, symptoms, or patient age. Because simple shave excision of the tumor can be safely achieved without evidence of tumor recurrence, we conclude that surgical resection can be reasonable in asymptomatic patients. 相似文献

Determining aortic stenosis (AS) severity is clinically important. Calculating aortic valve (AV) area by means of the continuity equation assumes a circular left ventricular outflow tract (LVOT). The full impact of this assumption in calculating AV area is unknown. Predictors of noncircular LVOT shape in patients with AS are undefined.In 109 adult patients with AS who underwent multiplanar transesophageal echocardiography, we calculated AV area by means of the standard continuity method and by a modified method involving planimetric LVOT area.We found 54 circular, 37 horizontal-oval, 8 vertical-oval, and 10 irregular LVOTs. Area derived by direct planimetry correlated better with the modified than the standard continuity method (r=0.89 vs r=0.85; both P=0.0001). Valve areas of patients with mild, moderate, or severe AS by planimetry were more often mischaracterized with use of the standard than modified method (29 vs 18; P <0.0001). Horizontal-oval AV area derived by planimetry (1.28 ± 0.55 cm2) was underestimated by the standard method (1.05 ± 0.47 cm2; P=0.001), but not by the modified method. Congenital AV morphology and low cardiac index were the only multivariate predictors of horizontal-oval shape. Low cardiac index was the only predictor of noncircular shape.More than half our patients with AS had noncircular LVOTs. Using the modified method reduces mischaracterizations of AS severity. Congenital AV morphology and low cardiac index predict horizontal-oval or noncircular shape. These data suggest the value of direct LVOT measurement to calculate AS severity in patients who have congenital AV or a low cardiac index. 相似文献

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital condition. It responds well to early diagnosis and treatment, but otherwise the prognosis is poor. We present our case series of 12 patients (mean age, 2 ± 2.58 yr; age range, 2 mo–8 yr), emphasizing the diagnostic process and discussing our surgical results. The diagnosis of ALCAPA should be suspected in infants who have dilated cardiomyopathy with electrocardiographic changes that suggest ischemia, and in older children who have isolated mitral regurgitation. When clinical suspicion is high, the results of 2-dimensional echocardiography combined with color-flow Doppler studies in expert hands can establish the diagnosis, thus avoiding angiography in critically ill infants. The treatment of choice in our patients was transfer and reimplantation of the left coronary artery onto the ascending aorta. There were 2 deaths: both were infants in extremis who underwent emergency surgery. An older child with severe ventricular dysfunction was given mechanical ventricular assistance and then heart transplantation. As of this report, all 10 survivors remained well and asymptomatic. 相似文献

We report the case of a 62-year-old woman who presented with classic symptoms of stable angina. Cardiac images and catheterization results revealed absent pulmonary valve syndrome and compression of the left main coronary artery by a massively dilated pulmonary artery aneurysm. The patient''s anginal symptoms were relieved after pulmonary arterioplasty.Others have described proximal left main coronary artery compression in the presence of a dilated and hypertensive pulmonary artery. To our knowledge, this is the first case in which a pulmonary artery aneurysm caused left main coronary insufficiency in the absence of pulmonary hypertension—a clinically important complication of congenital pulmonary valve-related pulmonary arteriopathy. 相似文献

We report the case of a 51-year-old woman who presented with stable angina pectoris and Canadian Cardiovascular Society class II functional capacity. An electrocardiogram during a treadmill exercise test showed substantial ST-segment depression in the inferolateral leads. Coronary angiograms revealed an anomalous origin of the left main coronary artery from the opposite sinus of Valsalva and an interarterial course between the ascending aorta and pulmonary artery. Although this phenomenon is dangerous, the patient refused further examination. We discuss the diagnosis and treatment of patients who have an anomalous origin of a coronary artery from the opposite sinus of Valsalva. 相似文献

Transposition of the great arteries encompasses a set of structural congenital cardiac lesions that has in common ventriculoarterial discordance. Primarily because of advances in medical and surgical care, an increasing number of children born with this anomaly are surviving into adulthood. Depending upon the subtype of lesion or the particular corrective surgery that the patient might have undergone, this group of adult congenital heart disease patients constitutes a relatively new population with unique medical sequelae. Among the more common and difficult to manage are cardiac arrhythmias and other sequelae that can lead to sudden cardiac death. To date, the question of whether implantable cardioverter-defibrillators should be placed in this cohort as a preventive measure to abort sudden death has largely gone unanswered. Therefore, we review the available literature surrounding this issue. 相似文献

Many patients who are in cardiogenic shock need mechanical support for clinical stabilization after acute insults such as myocardial infarction. However, the placement of advanced devices can be hindered by anatomic constraints or the physiologic sequelae of shock, as we describe in this report.A 67-year-old woman with prior coronary artery bypass grafting and extensive chest-wall scarring from previous defibrillator implantations presented with myocardial infarction and refractory cardiogenic shock. The patient''s vascular anatomy and prior surgery precluded conventional percutaneous implantation of an Impella 5.0 ventricular support device. We delivered the Impella device through the patient''s tortuous, vasoconstricted axillary artery with use of a vascular sheath and other percutaneous techniques. The success of this approach suggests that combining the expertise of cardiologists and cardiovascular surgeons can improve the outcomes of patients with complex anatomic issues. 相似文献
