Project description:Atresia of the right coronary artery ostium is a rare anatomic variant of the coronary circulation. It is often difficult to differentiate from single coronary artery. Its presence unassociated with any other anomaly has never been described in an adult individual. We report this unusual anomaly and discuss its anatomical and pathophysiological significance and possible ways to differentiate from single coronary artery.

Project description:Background Syphilitic ostial coronary stenosis is an uncommon manifestation of cardiovascular syphilis, characterized by concomitant aortic regurgitation and isolated or bilateral ostial involvement. Although much has been written about syphilis in the pre-antibiotic era, the key imaging and operative findings were rarely reported in the modern literature. Through multimodality imaging and operative videos, we demonstrate the unique diagnostic and therapeutic hurdles associated with the condition. Case Description A 47-year-old woman presented with acute decompensated heart failure due to bilateral ostial coronary stenosis and severe aortic insufficiency, which raises suspicion for underlying syphilis. She underwent successful aortic valve replacement, right coronary ostioplasty and bypass grafting of the left coronary system. The syphilitic process was confirmed by histopathological examination of the aortic valve and aortic wall as well as serological tests. She recovered from the operation uneventfully. Conclusions The manifestations of cardiovascular syphilis are protean and can pose significant diagnostic challenges even in the modern era. The presence of isolated coronary ostial stenosis should raise suspicion for syphilis. Timely surgery and antibiotics can lead to successful outcomes. Furthermore, the evolution and nuances of surgical techniques addressing ostial coronary stenosis was reviewed. Surgical strategy should be individualized based on preoperative multimodality imaging.

Project description:Calcified nodules in human coronary arteries are usually focally distributed. Non-invasive imaging of coronary arteries by bedside emergency transthoracic echocardiography in adults is possible and may become a useful adjunct to other methods of coronary artery examination. Coronary artery stenosis can be identified as localized color aliasing and accelerated flow velocities. Complete visualization of individual ostial coronary segments might ease the demonstration of coronary stenosis by bedside transthoracic echocardiography. The left main coronary artery stenosis requires prompt emergency evaluation and treatment because emergency conditions have higher mortality rates. The authors wish to emphasize the usefulness of emergency bedside echo-Doppler for a prompt diagnosis and treatment of this life-threatening condition.

Project description:In ostial or proximal left main coronary artery (LMCA) obstruction, re-establishment of normal antegrade flow via the main trunk may be preferable to distal bypass grafting. The objective of this study was to assess the effectiveness of patch plasty of the left main (LM) trunk of the coronary artery for more than 10 years. Direct widening of the LMCA was recommended to patients with ostial, proximal, or midpoint stenosis of the main trunk. Group I of 16 patients had isolated LM obstruction with no distal disease, and Group II of 15 patients had, in addition, right coronary obstruction. The mean age was 60.9 years (age group, 47 to 83 years). Nineteen patients underwent this operation through an anterior transverse aortotomy. No endarterectomies were performed. In Group II, in addition, a single saphenous vein bypass graft was placed in the right coronary artery. There were no operative deaths. Follow-up period extends from 10 to 18 years (mean 11.2). Eight patients had angiography from 3 to 9 years after surgery and all show adequate LM trunk caliber. Noncardiac deaths occured in five patients (26.3%) at 2 months, and 1, 4, 6, and 7 years after surgery. Two women with isolated ostial stenosis diagnosed as a spasm have not shown progression of coronary disease 7 to 9 years after the operation. Widening of the LMCA should be considered in selective cases, only when ostial, proximal, or midportion stenosis of the main vessel exist, even if a right coronary bypass graft is required.

Project description:Cardiovascular syphilis manifests many years after primary infection. Here, we report the successful treatment of a patient who developed syphilitic aortitis with bilateral coronary ostial stenosis and aortic insufficiency. The patient underwent right coronary artery bypass grafting, left main coronary ostial "open" stent placement, and mechanical aortic valve placement during open-heart surgery.

Project description:BackgroundTakayasu arteritis (TA) is a rare form of chronic inflammatory granulomatous arteritis of the aorta and its major branches. Late gadolinium enhancement (LGE) with magnetic resonance imaging (MRI) has demonstrated its value for the detection of vessel wall alterations in TA. The aim of this study was to assess LGE of the coronary artery wall in patients with TA compared to patients with stable CAD.MethodsWe enrolled 9 patients (8 female, average age 46±13 years) with proven TA. In the CAD group 9 patients participated (8 male, average age 65±10 years). Studies were performed on a commercial 3T whole-body MR imaging system (Achieva; Philips, Best, The Netherlands) using a 3D inversion prepared navigator gated spoiled gradient-echo sequence, which was repeated 34-45 minutes after low-dose gadolinium administration.ResultsNo coronary vessel wall enhancement was observed prior to contrast in either group. Post contrast, coronary LGE on IR scans was detected in 28 of 50 segments (56%) seen on T2-Prep scans in TA and in 25 of 57 segments (44%) in CAD patients. LGE quantitative assessment of coronary artery vessel wall CNR post contrast revealed no significant differences between the two groups (CNR in TA: 6.0±2.4 and 7.3±2.5 in CAD; p?=?0.474).ConclusionOur findings suggest that LGE of the coronary artery wall seems to be common in patients with TA and similarly pronounced as in CAD patients. The observed coronary LGE seems to be rather unspecific, and differentiation between coronary vessel wall fibrosis and inflammation still remains unclear.

Project description:BackgroundAlthough rare, angiosarcoma is the most common type of cardiac primary malignancy. This disease can cause life-threatening complications and the prognosis remains poor. There is no standard approach to care, and clinical judgement is exercised on a case-by-case basis. Tumour progression causes serious complications, such as heart failure and vascular disruption.Case summaryA 64-year-old Japanese woman presenting with a right atrial tumour was referred to our department. Tumour biopsy revealed that the patient suffered from angiosarcoma. We performed a lumpectomy to excise the tumour, but due to tissue adhesions in and around the right atrium, the malignancy could not be completely removed. After 3 years of chemotherapy, the patient was admitted to our hospital with increased chest pain. Emergency coronary angiogram revealed severe stenosis of the ostial right coronary artery. Intravascular ultrasound (IVUS) and computed tomography suggested coronary compression due to cardiac angiosarcoma. In this study, we report a unique case of advanced cardiac angiosarcoma, presenting as unstable angina, which was successfully treated with percutaneous coronary intervention using stent implantation.DiscussionDue to the rarity of cardiac primary angiosarcoma, many symptoms are misdiagnosed until mechanical complications arise, such as coronary compression. The clinical course and various imaging modalities are useful for differentiating angiosarcomas from coronary stenosis.

Project description:In patients with ostial coronary stents protruding into the aorta, there is concern for stent injury while undergoing transcatheter aortic valve replacement (TAVR) with balloon-expandable transcatheter heart valve (THV). An 82-year-old male with history of symptomatic aortic stenosis, heart failure, and coronary artery disease with multiple interventions to right coronary artery (RCA) and a history of stent fracture requiring stent-in-stent placement one year previously, was evaluated for TAVR. His ostial RCA stent was protruding into the aorta at the level of sinotubular junction, with ostial stent to aortic wall (SAW) distance of 25.2 mm. There was concern for balloon inflation during TAVR leading to stent injury. The RCA was cannulated with a 6 French JR4 guide and wired with 0.014' coronary wire. Appropriately sized noncompliant balloon was advanced into RCA. Under rapid pacing, the coronary balloon was inflated across the RCA ostium followed by simultaneous deployment of THV. Intravascular imaging of the ostial RCA stent revealed no stent fracture. SAW distance is important to determine the possibility of balloon-induced stent injury during valve deployment. In cases where an ostial stent may interact with balloon inflation, kissing-balloon inflation may be performed to prevent stent injury.Learning objectiveIn patients with ostial coronary stents protruding into the aorta, stent to aortic wall distance is important to determine the possibility of balloon-induced stent injury during balloon-expandable transcatheter heart valve deployment. Kissing-balloon inflation may be performed to prevent stent injury.
