Type A acute aortic dissection (TAAAD) is an acute cardiovascular condition that is normally associated with genetic conditions such as Marfan Syndrome, but it can also occur in patients with no known predisposing risk factors. TAAD is associated with extremely high mortality (over 20% of documented cases in medical literature) if not addressed on time. Surgical management of TAAAD also varies tremendously depending on the causative pathology. Techniques to manage TAAAD cover the entire spectrum of methods employed in cardiac surgery ranging from a simple replacement of the ascending aorta to aortic root sparing or replacement, and an aortocoronary bypass to total arch and descending aortic stenting involving hypothermic circulatory arrest or other cerebral protection strategies. New medical evidence suggests that concomitant, intraoperative management of the arch and descending aorta minimizes the need for subsequent surgeries in patients who are operated upon for TAAAD. Coupled with new diagnostic technology available to medical professionals, better long-term patient outcomes for TAAD treatment are now a reality. Recent Advances in Acute Type A Aortic Dissection presents a collection of comprehensive reviews from many experts on TAAAD. Cardiac surgeons can benefit from this volume by learning about current medical opinions and consensuses on risk factors (including genetic predisposition), diagnostic modalities, intraoperative management, surgical options, cerebral protection strategies, and long-term follow up procedures on acute TAAAD.

Acute medical management of aortic dissection. ~ Acute aortic dissection is a life-threatening disease. Current therapeutic guidelines recommend medical therapy with aggressive blood pressure lowering for patients with acute aortic dissection, when they are not indicated for emergency surgery. In particular, patients with aortic dissection without ascending aorta involvement (Stanford type B) are treated medically, unless they have fatal .

(PDF) A Contemporary Review of Acute Aortic Dissection ~ Acute aortic dissection is one of the most rapidly fatal clinical entities that can be encountered in the emergency department setting. Prompt establishment of the diagnosis, through focused .

Medical treatment for acute Type A aortic dissection ~ Acute Type A aortic dissection (AD) remains a surgical challenge with high early mortality. Immediate surgery is commonly recommended because of better prognosis when compared with medical treatment 1, 2]. Some patients are treated non-surgically due to compelling reasons, despite the need for surgery; medical treatment for these patients is another problem. We report our recent experience .

Hemiarch versus total aortic arch replacement in acute ~ Background: Despite recent advances in aortic surgery, acute type A aortic dissection remains a surgical emergency associated with high mortality and morbidity. Appropriate management is crucial to achieve satisfactory outcomes but the optimal surgical approach is controversial. The present systematic review and meta-analysis sought to access cumulative data from comparative studies between .

Contemporary results of surgery in acute type A aortic ~ Results. The overall in-hospital mortality was 25.1%. Mortality in group I was 31.4% compared with 16.7% in group II (P < .001).Independent preoperative predictors of operative mortality were history of aortic valve replacement (odds ratio = 3.12), migrating chest pain (odds ratio = 2.77), hypotension as sign of acute type A aortic dissection (odds ratio = 1.95), shock or tamponade (odds ratio .

A contemporary analysis of outcomes for operative repair ~ Background: Despite recent advances, reported mortality rates after repair for acute type A aortic dissection vary from 5% to 30%. This study was conducted to assess cross-sectional mortality after operative repair of type A dissection in the United States, and to determine whether a volume-outcome relationship exists for this operative procedure.

Acute type A aortic dissection in the elderly: clinical ~ Objectives We sought to evaluate the clinical characteristics, management, and outcomes of elderly patients with acute type A aortic dissection. Background Few data exist on the clinical manifestations and outcomes of acute type A aortic dissection in an elderly patient cohort. Methods We categorized 550 patients with type A aortic dissection enrolled in the International Registry of Acute .

Aortic Regurgitation in Acute Type-A Aortic Dissection: A ~ Acute type-A aortic dissection (ATAD) is defined as acute dissection proximal to the aortic arch with or without distal extension (Fig 2, Fig 3).5, 6, 7 This acute aortic syndrome is a surgical emergency because immediate surgical repair is considered the gold standard to optimize survival from this often lethal disease.5, 6, 7 Because this dissection process commonly will disrupt the .

ACC/AHA Aortic Dissection Guideline – emupdates ~ • Other risk factors for aortic dissection include conditions associated with increased aortic wall stress, such as hypertension (particularly if uncontrolled); pheochromocytoma; cocaine or other stimulant use; weight lifting or other Valsalva maneuver; deceleration or torsional injury (eg, motor vehicle crash, fall); and coarctation of the aorta. Conditions associated with aortic media .

Clinical Prediction of Acute Aortic Dissection / Surgery ~ ACUTE AORTIC dissection is the most frequently fatal condition in the spectrum of chest pain syndromes. 1,2 With undelayed diagnosis and optimal medical and surgical therapy, however, 30-day survival can exceed 90%. 1-4 Noninvasive imaging modalities permit rapid and safe diagnosis of dissection even in the early stage of intramural hematoma. 3,4 With poorly defined criteria for imaging of the .

Management of acute aortic dissection and thoracic aortic ~ Aortic dissection. Acute aortic dissection is defined as dissection occurring within 2 weeks of onset of pain [].Subacute and chronic dissections occur between 2 and 6 weeks, and more than 6 weeks from the onset of pain, respectively [].Two classifications are most commonly used for aortic dissection (Fig. 1).The DeBakey system is classified into three types (types I, II, and III) according to .

Guide To Aortic Dissection Types - HealthPrep ~ Acute aortic dissection and chronic aortic dissection are terms used to classify both types of aortic dissections based on the onset and duration of the tearing process that occurs an individual's aorta. An acute aortic dissection is characterized by a dissection that immediately produces symptoms when it occurs. Sudden back and or chest pain are the symptoms that present most often in .

Acute type A dissection is often lethal unless emergency surgery is done. I suspect that most patients with acute type A aortic dissections are operated on by surgeons with limited experience in aortic surgery, which may explain why the operative mortality and morbidity remain high for this .

Evolution of diagnosis and clinical outcomes in acute ~ However, recent advancements in endovascular repair should lead to better outcomes in managing type B AAD. According to data from the INSTEAD trial, in which endovascular repair was performed for uncomplicated subacute/chronic type B aortic dissection, the aortic remodeling rate after endovascular repair was much higher than that with medical treatment (91.3% versus 19.4%, P<0.001). Although .
