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.

[Right heart support during coronary artery bypass grafting without cardiopulmonary bypass]

BACKGROUND AND OBJECTIVES

Exposure of lateral and inferior coronary vessels during off-pump coronary artery bypass grafting may cause significant hemodynamic compromise due to right ventricular compression when tilting the heart. Some new right ventricular assistance devices have been developed in order to avoid this problem but only a few series have been published. A preliminary experience with a right heart circulatory support system is reported.

METHODS

A total of eight patients underwent off-pump coronary artery bypass grafting using a right heart support device. Technical procedure and clinical outcome are analyzed.

RESULTS

The right heart circulatory support device insertion and management were performed without any complication. A total of 21 distal coronary anastomoses were completed. They were located on the anterior descending artery(8), circumflex branches(6), diagonal branches(2), posterior descending artery(3) and right coronary artery(2). The right ventricular support device delivered flow at a medium rate of 2.2 L/min, providing hemodynamic stability when tilting the heart and exposing the coronary arteries.

CONCLUSIONS

The use of right heart support devices is a simple and low risk procedure which may facilitate surgical anastomoses on lateral and inferior epicardial vessels during off-pump coronary artery surgery.

[Evaluation and treatment of cardiac injuries]

Cardiac injuries caused by a heart traumatism are not frequent but, of great importance given their high morbidity. Two different groups in terms of etiology, clinical picture, application of diagnostic techniques, treatment and prognosis can be considered. On one hand, there are cardiac injuries caused by a thoracal contusion, which provokes a contused lesion can affect the free wall, the interventricular septum, the valves, the subvalvular apparatus, the conduction system and the coronary vessels and, on the other hand, cardiac injuries caused by penetrating objects. Cardiac injury can lead to a life-threatening hemodynamic instability which mandates prompt and clear diagnostic and therapeutic approaches.

The withholding and withdrawal of medical treatment: moral principles and the law #

In most hospitals in Puerto Rico the dying process of terminally ill patients is inappropriately prolonged. And this occurs often without the patient's consent and in violation of basic ethical principles. Three erroneous beliefs are prevalent: 1--That withdrawing life support therapy is morally or legally different from not starting it. 2--That there is a moral and legal difference between appropriate acts and appropriate omissions. 3--That good medical practice is determined by the courts instead of the medical profession. Institutional policies are not in harmony with contemporary medical ethics. To avoid possible legal entanglements medical institutions permit their faculties to prolong the suffering of patients in violation of two basic moral principles: nonmaleficence and respect for autonomy. An illustrative case provides a philosopher and a moral theologian the opportunity to analyze the applicable moral principles. A professor of jurisprudence reviews statutes evolved at the State and Federal level that support the rights of patients and their families to refuse unwanted treatments. Medical faculties must ensure that institutional policies do not violate their professional ethics. The medical profession and the citizenry at large should lobby for the passage of statutes in Puerto Rico which clearly validate the necessary harmony between medical ethics and the law.

[Right coronary artery originating from the left sinus of Valsalva. Surgical repair]

Anomalous origin of right coronary artery from left coronary sinus has been considered a minor disease without relevance. Currently it is associated with all symptoms derived from myocardial ischemia because of its lower coronary reserve. We present one patient with anomalous origin of right coronary artery from left coronary sinus surgically treated with saphenous vein aorto-coronary bypass. Doppler velocimetry shows the improvement of myocardial reserve after surgery.

[Factors affecting early graft patency after coronary grafts]

From June 1984 to December 1987, an early postoperative angiographic study was performed in 247 patients who underwent isolated coronary artery bypass surgery. The average age of these patients was 58.6 years, range 31 to 75 years. Preoperatively 50.8% of patients had myocardial infarction and 43.2% of them had unstable angina before surgery. Early coronary artery bypass angiogram was performed in 683 grafts (2.76 grafts per patient): 74 internal mammary artery grafts and 609 saphenous vein grafts. The distribution, location and type of the stenosis, distal coronary artery diameter, segmental myocardial contractility, and distal angiographic coronary filling are analyzed with a matching statistical method. Multivariate analysis showed significant predictors of early graft occlusion to be right coronary and circumflex artery, poor or non visible distal angiographic filling, coronary arteries smaller than 1.5 mm. The univariate analysis associates as risk factors hypokinetic or akinetic territories and multiple stenosis coronary arteries. It can be concluded that the early angiographic study demonstrate that coronary arteries with multiple stenosis, poor distal angiographic filling, smaller than 1.5 mm in diameter, coronary arteries perfusing hypokinetic or akinetic territories and the right coronary and left circumflex artery grafts have significantly lower early cumulative patency rates.

[Use of both internal mammary arteries; not everything is advantageous]

The internal mammary artery is considered the elective graft for performing aortocoronary by-pass as its long-term results have proven better than those obtained with the internal saphenous vein. Our results in a series of 21 patients in whom both internal mammary arteries were used are reported. Four patients (19.04%) needed reoperation for sternal dehiscence and two of them had mediastinitis (9.52%). Those patients were successfully treated by continuous povidone-iodine flushing. A clear statistical difference was found between this group of patients, in whom both internal mammary arteries were used, and the rest of the patients (182 patients) in whom just the internal saphenous vein and/or only one internal mammary artery was used. The second group presented 8 cases of sternal dehiscence (4.39%) and 1 mediastinitis (0.55%).
