Patients with severe aortic atherosclerosis are at high risk for stroke. The risk is highest for those with atherosclerotic plaque measuring = or >4 mm in thickness. There is currently no proven medical therapy to reduce embolic risk in patients with aortic plaque. Antiplatelet therapy, smoking cessation, and management of ...

Cerebral ischemia, bleeding, and inadequate myocardial protection are the major concerns in doing aortic arch operation. The trifurcated graft technique as described by Spielvogel and associates was a useful technique in reducing the risk of postoperative neurologic complications. However, the cerebral ischemic time may be still too long in inexperienced ...

Re-sternotomy for aortic valve replacement (AVR) in patients with a patent internal mammary artery (IMA) graft may present a challenging surgical problem. Thus, strategies to prevent IMA graft injury include avoiding its dissection and leaving the graft open. However, when aortic cross clamping and cardioplegia are required, this approach may ...

BACKGROUND: Aortic valve sclerosis, without stenosis, has been associated with an increased cardiovascular mortality and morbidity due to myocardial infarction. However, it is unclear whether it is a cardiovascular risk factor or a cardiac disease marker. The goal of our study is to evaluate the difference in the prevalence of ...

Aortic arch atherosclerosis is associated with an increased risk of stroke or TIA. Up to now, transesophageal echocardiography has been the standard method for diagnosing protruding and/or mobile aortic arch atherosclerosis. We report a case where a mobile aortic arch atheroma was diagnosed using transthoracic echo in a patient with ...

In aortic valve-sparing surgery, the native valve of the patient is left in place but may need correction of its dimensions in order to regain full competence. A sizer was designed that can simultaneously measure the leaflet height and free edge length. A prototype was built and successfully used in ...

Intra-aortic balloon pumping (IABP) has been considered to be relatively contraindicated in patients with complex aortic stenosis (AS). In this report, we describe the successful implementation of IABP counterpulsation in a patient with severe coronary artery disease and left ventricular dysfunction complicating significant aortic AS. It is shown that adjuvant ...

Images are presented of coronary reperfusion that occurred shortly after insertion of an intra-aortic balloon pump for counter-pulsation in 3 patients with acute myocardial infarction refractory to thrombolytic therapy and hemodynamic derangement. It is shown that prophylactic intra-aortic balloon pump use may facilitate percutaneous coronary intervention during acute myocardial infarction ...

Hypoplastic left heart syndrome (HLHS) refers to the abnormal development of the left-sided cardiac structures, resulting in obstruction to blood flow from the left ventricular outflow tract. In addition, the syndrome includes underdevelopment of the left ventricle, aorta, and aortic arch, as well as mitral atresia or stenosis. HLHS has ...

Aorto-ventricular tunnel is a congenital, extracardiac channel which connects the ascending aorta above the sinutubular junction to the cavity of the left, or (less commonly) right ventricle. The exact incidence is unknown, estimates ranging from 0.5% of fetal cardiac malformations to less than 0.1% of congenitally malformed hearts in clinico-pathological ...

OBJECTIVE: We compared the echocardiographic geometry of the preoperative and postoperative left ventricular outflow tract in children and adults with isolated fixed subaortic stenosis with age- and weight-matched controls to elucidate whether the geometry can be modified when surgical intervention is performed at a younger age. METHODS: The mitral-aortic valve ...

BACKGROUND: Type 2 diabetes mellitus (DM2) may augment arterial stiffening and thereby modulates left ventricular (LV) function. Cardiovascular magnetic resonance (CMR) is well suited to assess aortic pulse wave velocity (PWV) and aortic distensibility, both markers of arterial stiffness, without the use of geometric assumptions. Furthermore, CMR is a reliable ...

We evaluated the short-term safety and efficacy of using the TandemHeart(R) percutaneous ventricular assist device in high-risk patients undergoing aortic valvuloplasty procedures. Aortic valvuloplasty was performed in 4 patients who had no ventricular assist device support and in 7 patients who used the TandemHeart for hemodynamic support. The age range ...

We report a 23-year-old patient undergoing functionally univentricular repair who developed cardiac failure due primarily to systemic ventricular dysfunction. The failing Fontan circulation was successfully re-established using intra-aortic balloon counterpulsation. Aortic counterpulsation facilitates recovery of systemic ventricular function, and appears to be a reasonable alternative in select instances of cardiac ...

BACKGROUND: Aortic atresia or severe aortic stenosis and left ventricular outflow tract obstruction is a frequent component of complex congenital heart disease. Aortic atresia or severe aortic stenosis and left ventricular outflow tract obstruction with two adequate ventricles is sometimes treated by Norwood palliation followed by late biventricular repair. We ...

OBJECTIVE: Aortic stiffness can lead to low diastolic blood pressure, thereby possibly limiting coronary perfusion. Therefore, the simultaneous occurrence of both aortic stiffness and coronary atherosclerosis can lead to an increased risk of subendocardial ischaemia. The aim of the present study was to investigate the association between aortic stiffness and ...

There are several methods for surgical management of aortic insufficiency in patients with end-stage congestive heart failure who are undergoing implantation of a left ventricular assist device (LVAD). To date, little is known about the long-term outcome of bioprosthetic valves for aortic insufficiency in patients with continuous flow LVADs. We ...

A 5-year-old child with hypoplastic left heart syndrome presented with myocardial infarction 2 years after Fontan completion. Evaluation identified a thrombus in his native aortic root. Retrospective review of a prior catheterization revealed stasis in the native aortic root. Surgical thrombectomy was performed after failed medical management. The neoaortic root ...

PURPOSE OF REVIEW: Progressive aortic root dilatation is a recognized feature of tetralogy of Fallot even in patients following initial reparative surgery. The underlying pathophysiology was initially attributed to altered hemodynamics resulting from longstanding volume overloading and stretching of the aortic root from increased right to left shunting. This review ...

In patients with severe aortic valve stenosis (valve area <or= 1 cm(2), AS), the prevalence and the prognostic impact of comorbidities is unknown. Fifty-eight patients with severe AS (mean aortic valve area 0.8 +/- 0.2 cm(2)), who underwent cardiac catheterization and 2-D/Doppler echocardiography, were prospectively enrolled. The glomerular filtration rate ...

Aortic dissection limited to one sinus of Valsalva has been described exclusively as an iatrogenic complication during catheterization interventions. This life-threatening subtype had a very small area of dissection, when coronary ostia are frequently involved. We report a 43-year-old man with dissection limited to left sinus of Valsalva, involving the ...

BACKGROUND: Although gelatin-resorcinol-formaldehyde (GRF) glue is used for surgical repair of acute type A aortic dissections, late complications possibly ascribed to toxic effects of GRF glue have been reported. We analyzed the benefits and risks of using GRF glue. PATIENTS AND METHODS: Between January 1990 and August 2003, 269 consecutive ...
Litmathe J - - 2006
BACKGROUND: The operative risk of combined aortic and mitral surgery is still between 5 and 13 %, whereas isolated AVR normally causes complications in less than 4 % of all patients. Thus, it was the aim of the study to compare both procedures and to evaluate risk stratification in our ...
