Fluid dynamics of aortic root dilation in marfan syndrome

Metrics details. Marfan syndrome, a genetic disorder of the connective tissue, may cause aortic root dilation with aortic insufficiency, aortic dissection and mitral prolapse with mitral insufficiency. We present a case of a late complication of the modified Cabrol procedure that included replacing the ascending aorta with a composite graft.

In Februarya year-old female patient with Marfan syndrome who presented with chest pain was sent to the Emergency Department. Upon presenting, laboratory analysis revealed elevated troponin-I levels. Contrast computed tomography CT revealed thrombosis in the Dacron graft. Percutaneous coronary angiography was conducted, and a large thrombus in the graft was noted.

Thrombolytic therapy and percutaneous coronary intervention were performed, after which the patient had no more symptoms and was discharged without complications. Aortic root surgery, including the Cabrol or modified Cabrol procedure, is necessary for complicated cases of aortic dilations, such as in patients with Marfan syndrome, even though the Cabrol or modified Cabrol procedure has a high complication rate. Regarding this case, we were surprised by the timing of the myocardial ischemia and the position of the thrombus, which differed from other cases.

Peer Review reports. Marfan syndrome is a disorder caused by an autosomal dominant genetic variation of the connective tissue. Since connective tissue is found over the whole body, Marfan syndrome is associated with a broad range of related disorders and can present with various severities. Ocular, cardiovascular, and musculoskeletal abnormalities, even involving the central nervous system, can occur.

Among all complications, aortic root dilation with aortic insufficiency, aortic dissection and mitral prolapse with mitral insufficiency are common cardiovascular conditions in Marfan syndrome [ 1 ]. The modified Cabrol procedure is one of the techniques. One of the Cabrol modifications that has gained popularity is reimplanting either the right or left coronary ostium with a separate interposition graft.

The Cabrol graft procedure and its modifications can be safely utilized for complex aortic root replacement procedures. According to the study of Ziganshin et al.

However, there have been reports mentioning occlusion of the Cabrol graft and stenosis of the graft-coronary anastomosis. The patient was successfully treated with a percutaneous coronary intervention and discharged without complications [ 23 ].

A year-old woman with Marfan syndrome experienced acute chest pain while asleep and was sent to the Emergency Department of National Taiwan University Hospital-YunLin Branch at midnight.

Ten years prior, the patient underwent the modified Cabrol procedure due to an aortic root aneurysm at Kaohsiung Medical University Hospital. The procedure interposed a mm St.

An 8-mm-diameter Dacron graft was anastomosed end-to-side to the composite graft and end-to-end to the orifice of the left main coronary artery. Anticoagulation therapy with warfarin sodium was started on the first postoperative day, and the target international normalized ratio was 1.

Due to the previous medical history, she was transferred to Kaohsiung Medical University Hospital. Initial cardiac biomarkers showed elevated troponin I of She was diagnosed with acute non-ST-elevation myocardial infarction. Contrast computed tomography revealed a thrombosis in the Dacron graft Fig. Due to persistent chest discomfort and the above findings, coronary artery occlusion was highly suspected, even though she had no risk factors, such as hypertension, hyperlipidemia, diabetes mellitus or smoking.

We instantly arranged a percutaneous coronary angiography, and many thrombi were found in the graft. We further utilized an Accuforce balloon of 2. The anastomosis site of the Dacron graft and natural left main coronary artery was uncertain because of the residual thrombus after aspiration during the first percutaneous coronary intervention PCI ; therefore, the placement of the stent was intervened.

For the above reasons, thrombolytic therapy and a second PCI were chosen despite a lack of previous experience.

Warfarin sodium was maintained, and the target international normalized ratio was 2.DFBs offer our tightest spreads but are subject to a funding adjustment each night.

Petra did an amazing job of lining up incredible sights and accommodations during our 11 day trip- thank you for all of your expertise and assistance.

Glyn and Bozena, United Kingdom Romance Around Iceland, September 2016 Our whole honeymoon was amazing from start to finish and we would just like to thank Sigfus for putting all the hard work in to making it so special for us.

From the personalised itinerary to the highlighted road map with all the stops annotated with times and dates it felt like we were your only customers. Jackson and Kelsey, United States Romance Around Iceland, August 2016 Nordic Visitor made it so easy to explore Iceland on our honeymoon. We were able to avoid the stress of booking hotels or rental cars in a foreign, unfamiliar country, while also having the freedom to do all the things we wanted. Their materials were super helpful, and their staff was always there to answer our questions along the way.

We absolutely LOVED our trip, and will be booking with Nordic Visitor again. Emma, United Kingdom Norway Explorer, August 2016 Superbly organised, clear information with just enough detail not to be overwhelming.

The tour was perfectly split into manageable driving lengths. Receiving the travel documentation was very exciting, wouldn't have been the same in digital form. I loved the map with the hotel names written on. The choice of hotels was varied and of a high standard. I was able to research hotel facilities such as car parking and kettles in rooms using trip advisor.

That was really the only info missing to aid my planning. I felt that we were in safe hands and that should we have needed advice and support, it would've been there. Thank you for an excellent service. The three of us had a memorable journey through Norway, stayed in great accomodation and enjoyed great breakfasts. The travel was well spaced with plenty of time to move to the next step of the journey.

Caitlin and Siim, United States Hidden Gems of Iceland, August 2016 I cannot say enough good things about our tour with Nordic Visitor. Barry and Carolyn, United States Express Iceland, August 2016 This was our first trip with Nordic Visitor and we expect that it won't be our last. Ingrid, United Kingdom Family Fun in South Iceland, August 2016 We were very impressed with the service.

Bobbi, United States Adventures Around Iceland, July 2016 This is not the type of vacation we normally take - we have generally gone on Caribbean Cruises, but our son was reading a brochure about Iceland and had heard some of his classmates from school talk about Iceland and he thought he'd like to do this for a summer vacation.
