Anaesthetic-surgical guide in the treatment of ascending aorta and surgery of the ascending aorta and aortic arch. Consensus document of the Spanish Society of Cardiovascular and Endovascular Surgery and the Sociedad of Anaesthesiology, Resuscitation and Pain Therapy.

Aortic pathology is always a challenge for the clinician, and must be diagnosed and treated by a multidisciplinary team due to the technical and technological complexity of the resources used. Ongoing efforts to implement a systematic, protocolized approach involving "Aortic teams" made up of cardiologists, cardiac surgeons, vascular surgeons, anaesthesiologists and radiologists, among others are now leading to improved outcomes. The aim of this consensus document drawn up by the Aortic working groups of the Spanish Society of Anaesthesiology, Resuscitation and Pain Therapy (SEDAR) and the Spanish Society of Thoracic and Cardiovascular Surgery (SECTCV) is to disseminate a set of working protocols. The latest consensus document of the European Association for Cardio-Thoracic Surgery (EACTS) and the European Society for Vascular Surgery (ESVS) define the concept of "AORTIC TEAM"(1). The aortic team should be closely involved from diagnosis to treatment and finally follow-up, and should be formed of cardiac and vascular surgeons working together with anaesthesiologists, cardiologists, radiologists and geneticists. Treatment of aortic pathologies should be centralised in large centres, because this is the only way to effectively understand the natural course of the disease, provide the entire range of treatment options under one umbrella and treat potential complications. A streamlined emergent care pathway (24/7 availability), adequate transportation and transfer capabilities, as well as rapid activation of the multidisciplinary team must be available. In light of the complexity and constant evolution of therapeutic options, we present this first version of the Anaesthesiology and surgical guidelines for surgery of the ascending aorta and aortic arch. Some questions will no doubt remain unanswered, and future versions will include new techniques that, though implemented in some centres, are still not widely recommended.

Accuracy of noninvasive estimation of pulmonary wedge pressure by echocardiographic indices in heart transplant recipients.

BACKGROUND: Pulmonary capillary wedge pressure (PCWP) can be estimated from transmitral or color M-mode Doppler flow propagation velocities. However, it has been recommended to not use these indices in heart transplant recipients. Our aim was to compare the accuracy of color M-mode, Doppler, and Doppler tissue imaging (DTI)-derived indices to predict PCWP in heart transplant recipients. METHODS: We studied 50 consecutive heart transplant recipients scheduled for routine right-sided heart catheterization and endomyocardial biopsy. Their mean age was 49 ± 17 years and the mean time after heart transplantation was 29 ± 41 months. An echocardiogram was performed immediately after the invasive procedure. We analysed PCWP, transmitral flow velocity variables (peak velocity during early filling (E) and deceleration time [DT]), color M-mode Doppler flow propagation velocity (Vp), and mitral annulus peak early diastolic velocity (E') from DTI. Doppler estimated-PCWP (ePCWP) was calculated as follows: (5.27 × E/Vp) + 4.6. RESULTS: Mean ejection fraction was 66 ± 11%. The mean invasive measured PCWP was 11.14 ± 5.4 mm Hg and the mean noninvasive ePCWP was 11.13 ± 1.8 mm Hg (r = 0.66; P < .0001). A good correlation was present between invasive PCWP and mitral PW-Doppler and DTI parameters: peak E 91 ± 22 cm/s (r = 0.34; P = .02) and DT 143 ± 26 s (r = -0.436; P = .002), E/E' ratio medial mitral annulus 10 ± 4 cm/s (r = 0.353; P = .026) and E/E' ratio lateral mitral annulus 6 ± 2 cm/s (r = 0.462; P = .002). E/Vp was the most accurate index for predicting PCWP (r = 0.615; P < .0001). CONCLUSIONS: Compared with other indirect Doppler indices, E/Vp showed the best correlation to predict PCWP in heart transplant recipients. Despite previous recommendations, PCWP can be accurately estimated from color M-mode indices, giving useful information and avoiding the risks of invasive measurements.

Mechanisms of ischemic stroke in HIV-infected patients.

OBJECTIVE: To evaluate the types and mechanisms of stroke in a large population of HIV-infected patients. METHODS: We reviewed records of consecutive HIV-infected patients with acute stroke admitted to a large metropolitan hospital between 1996 and 2004. Stroke mechanism was defined by consensus between two cerebrovascular neurologists using TOAST classification. RESULTS: A total of 82 patients were included, 77 with ischemic stroke and 5 with intracerebral hemorrhage. Mean age was 42 years and 89% were African American. Previous diagnosis of HIV infection was documented in 91% and AIDS diagnosis in 80%. Mean CD4 count was 113 cells/mm(3) and 85% had CD4 count <200 cells/mm(3). A total of 61% of patients had received combination antiretroviral treatment (CART). The mechanism of ischemic stroke was large artery atherosclerosis in 12%, cardiac embolism in 18%, small vessel occlusion in 18%, other determined etiology in 23%, and undetermined in 29% (including 19% with incomplete evaluation). Vasculitis was deemed responsible for the stroke in 10 patients (13%) and hypercoagulability in 7 (9%). Protein S deficiency was noted in 10/22 (45%) and anticardiolipin antibodies in 9/31 (29%) tested patients. When comparing patients with large or small vessel disease (atherothrombotic strokes) vs the rest of the population, there were no differences in exposure to CART or CD4 count, but patients with non-atherothrombotic strokes were younger (p = 0.04). Recent cocaine exposure was less common among patients with atherothrombotic strokes (p = 0.02). Strokes were fatal or severely disabling in 35% of cases. CONCLUSIONS: Stroke mechanisms are variable in HIV-infected patients, with a relatively high incidence of vasculitis and hypercoagulability. In our population of severely immunodepressed patients, exposure to combination antiretroviral treatment did not significantly influence the mechanism of stroke.

The importance of preventive health care in post-menopausal women.

Women make up 55% of the total world population. This percentage is set to steadily increase over the next three decades. Europe also has the highest proportion of older women in the world. In fact, there are now approximately 3 women for every 2 men over 65. All of this data confirms the importance of prevention. An ideal approach for the female post-menopausal population would be treatment of any condition that can improve physical, mental and social well-being. Nevertheless, it is understood that the efficacy and cost/benefits of every screening programme need to be analysed. One of the largest and most neglected groups that could benefit from prevention consists of women without hot flushes (asymptomatic women), but with risk factors. The strategic measures are information, research and development of programmes. The more practical approach would be to identify patients and therefore yield better results in terms of health status and improvement. Statistics show that the three main causes of mortality and disability in developed countries for post-menopausal women are cardiovascular disease (CVD), cancer and osteoporosis-associated fractures. There are agreed recommendations to include some preventive measures for these three disorders in clinical practice for health professionals, at least at the minimal level. Research into the role that other diseases play will allow strategies to be developed in order to enhance prevention. Disorders such as urinary incontinence, dyspareunia, visual and hearing impairment and cognitive dysfunction are seen in significant percentages in post-menopausal women and may affect their quality of life. Health care professionals should bear in mind that many women may be reluctant to raise questions about some disorders spontaneously. Physicians should therefore search for patients with risk factors for these diseases. Prevention and treatment to avoid medical accidents will improve the quantity and quality of life.

Surgical treatment of nonbacterial thrombotic endocarditis presenting with stroke.

BACKGROUND: Necropsy studies have shown that nonbacterial thrombotic endocarditis (NBTE) may be associated with cerebral infarctions and antemortem diagnosis is now possible. However, the best treatment for patients with NBTE presenting with stroke is not known. We describe three patients presenting with an acute embolic stroke secondary to large,mobile vegetations detected by transthoracic (one case) or transesophageal echocardiography (two cases). All patients underwent surgery for removal of the vegetations to prevent recurrent embolic events; valve replacement was necessary in two cases. The sterile nature of the vegetations was confirmed by pathological examination and negative stains and cultures of the surgical samples. A previously unrecognized hypercoagulable condition was diagnosed in all patients (antiphospholipid antibody syndrome in two cases and disseminated adenocarcinoma in one case). CONCLUSION: NBTE should be considered among the possible causes of embolic stroke even in the absence of history of cancer, hypercoagulability, or previous embolic manifestations. If NBTE is diagnosed, the possibility of underlying thrombophilia should be thoroughly investigated. Valvular surgery represents a valuable therapeutic alternative in patients with large mobile vegetations, valvular dysfunction or recurrent embolic events despite anticoagulation.

Hydatid disease of the interventricular septum causing pericardial effusion.

Echinococcal infestation of the heart is uncommon. We report a case of a 35-year-old man with an hydatid cyst located in distal interventricular septum. Clinical presentation was chest pain and urticaria. Diagnosis was made by echocardiography and magnetic resonance imaging. Surgical resection was performed; the cyst was punctured and its content was drained, hypertonic glucose solution was instilled for sterilization, and it was removed. The patient did well and remains asymptomatic. Diagnosis and ultimate surgical treatment of this disease prevented potentially lethal complications such as cyst rupture with embolic phenomena and anaphylactic shock.

[Angioplasty and stenting in carotid stenosis. Therapeutic alternative or technical possibility?]. / Angioplastia y stenting de la estenosis carotídea. Alternativa terapéutica o posibilidad técnica?

OBJECTIVE: Review the current knowledge on the use of angioplasty and stenting (A/S) for the treatment of carotid stenosis with emphasis on proposed indications. DEVELOPMENT: The standard treatment for carotid stenosis is carotid endarterectomy (CE). However, excessive surgical risk and/or technical difficulty occasionally impose limitations on the surgical approach. Therefore, the option of percutaneous treatment with A/S becomes an appealing alternative. A/S techniques are constantly improved but there is very little prospective data supporting its value at present. The reported complication rates appear comparable to those of CE. Indications for A/S of the carotid artery are not fully delineated yet. We believe that adequate candidates for carotid A/S must have symptomatic high-degree carotid stenosis and at least one of the following situations: unstable coronary disease, severe systemic disease, surgically inaccessible carotid lesion (including some cases of carotid stenosis secondary to neck radiation), contralateral carotid occlusion, or recurrent stenosis after prior CE. CONCLUSIONS: A/S represents a promising alternative to CE in the treatment of carotid stenosis. However, in the absence of prospective comparative trials, A/S should be currently reserved exclusively for those patients in whom surgery is prohibited by very high surgical risk or technical inaccessibility. A/S of the carotid artery should only be performed by operators with ample expertise in the field.

[Surgical reconstruction of intervalvular fibrous body in active infective endocarditis]. / Cirugía de reconstrucción del cuerpo fribroso intervalvular en la endocarditis infecciosa activa.

INTRODUCTION AND OBJECTIVES: Surgery for infective endocarditis with paravalvular abscesses and fibrous body destruction has the highest mortality and morbidity rates in this disease with high surgical risk. We report a new approach of radical resection of the abscess and affected tissues and reconstruction of the heart with pericardium as an alternative to conventional surgery. METHODS: In the last two years six patients with infective endocarditis, paravalvular abscesses and fibrous body destruction underwent surgery (five prostheses with infective endocarditis). The main indication for surgery was persistent sepsis despite adequate antibiotic treatment in five patients and congestive heart failure in one. After wide resection of the abscesses and fibrous body the heart was reconstructed with glutaraldehyde-fixed bovine pericardium. RESULTS: There was no hospital mortality. The median bypass and clamp times were 198 and 174 minutes, respectively. One patient presented complete AV block and a permanent transvenous pacemaker was implanted. Doppler echocardiographic studies performed in all the patients prior to discharge indicated that no patient had patch dehiscence or paravalvular leaks. Patients were followed a mean of 15 months with no deaths or other complications being reported. CONCLUSIONS: Resection of the abscesses and fibrous body, and reconstruction of the heart with glutaraldehyde-fixed bovine pericardial patch is a radical, feasible technique with all infected tissues being resected to thereby prevent reinfection or paravalvular leaks.

[Detection of microembolus with transcranial doppler]. / Detección de microémbolos con Doppler transcraneal.

OBJECTIVES: To review techniques and the most important clinical applications of microembolus detection with transcranial Doppler. DEVELOPMENT: Technical aspects of microembolus detection are discussed initially; clinical circumstances in which embolus detection is currently used follow, such as carotid stenosis, cardiac pathology, monitoring during neuroangiography, coronary revascularization surgery and endarterectomy. Lastly, the potential clinical applications of this technique are reviewed: localization of an embolic source, risk of recurrent ischemia in patients with unstable atherosclerotic plaques, intraoperative monitoring and potential surgical technique modifications based on this information, contributions to the understanding of the pathophysiology of the fat embolism syndrome, and monitoring therapeutic efficacy of antithrombotics and thrombolytics. CONCLUSIONS: The ability to detect cerebral emboli with transcranial ultrasound has increased significantly our understanding about the pathogenesis of cerebral ischemia. Microembolus detection with transcranial Doppler is a powerful and novel diagnostic technique that allows to study the embolic process in vivo and in real time, instead of using indirect indicators of embolism (clinical and radiological features, possible embolic sources, etc.).

[Neurological complications of aortic artery surgery]. / Complicaciones neurológicas de la cirugía de la arteria aorta.

INTRODUCTION: Improvement in cardiac surgery techniques has led to a considerable reduction in mortality following surgery of the aorta, dissection of the aorta and for aortic aneurysms. Although there are satisfactory vascular results following surgical repair, morbi-mortality related to neurological complications, both cerebral and spinal, is still very high. Repair of aortic lesions may lead to damage by two main mechanisms: ischemia secondary to prolonged obstruction of the aorta or to neurological lesions due to total circulatory arrest. DEVELOPMENT: After description of the mechanisms leading to cerebral and spinal lesions and the risk factors involved, we discuss methods of vascular protection and other means of neuro-protection, both spinal and cerebral. Of the vascular techniques for spinal protection, the most useful ones are short-circuits, or active or passive shunts, and cardiopulmonary by-pass. Amongst the vascular techniques for cerebral protection we describe total circulatory arrest and methods of anterograde and retrograde cerebral perfusion, and when these may be used. As general measures for nervous system protection, we describe the use of hypothermia and drugs such as corticosteroids, free radical blockers, antagonists of the excitatory amino-acids etc. CONCLUSIONS: In spite of the number of studies done, the extreme sensitivity of the nervous system to ischemia has meant that in few cases have encouraging results been seen. Neurological damage continues to be the main cause of morbi-mortality in patients with dissection or aneurysm of the aorta.

Hydatid cyst of the interventricular septum in a 3.5-year-old child.

An asymptomatic cardiac cyst located in the interventricular septum was diagnosed in a 3.5-year-old child by echocardiographic findings. Surgical ablation was done and histopathologic analysis confirmed a hydatid cyst. The patient was discharged without symptoms.

[Aortic valve replacement via ministernotomy]. / Sustitución valvular aórtica por miniesternotomía.

Minimally invasive cardiac surgery is arising as an alternative technique in some cardiac operations. We present the first aortic valve replacement via ministernotomy. We describe in detail the technique of ministernotomy and the limitations that this new approach would have. We conclude with the advantages of minimally invasive cardiac surgery over conventional approach and review other techniques described in the literature.

Occipital lobe tumor presenting as migraine with typical aura.

We report the case of a 60-year-old woman in whom migraine with typical aura heralded the presence of an occipital lobe tumor. Her headache was characterized by recurrent episodes of visual aura confined to the left visual field followed by right hemicranial throbbing headaches accompanied by nausea, photophobia, and phonophobia. Interictal neurologic and ophthalmologic examinations were negative, as was an unenhanced brain CT scan. The headaches increased in frequency over 4 months despite a number of medications known to prevent attacks of migraine. A low-grade right occipital lobe tumor was eventually discovered on MR scan. This case illustrates that headache fulfilling the International Headache Society (IHS) criteria for migraine with typical aura can occur in association with an occipital lobe tumor.
