Congenital anomalies originating it the coronary arteries are of special interest for forensic specialists. The presented case is a man found dead on the Coast of Marmara Sea. The death was considered to be suspicious and an autopsy was performed. On the macroscopic autopsy, the ostium of the right coronary artery was hole-like, located in a normal position, but the ostium of the left coronary artery was pocket-shaped and located in the left wall of the ascending aorta and above the rim of the sinotubular junction. We describe an asymptomatic, but didactic case with ectopic high origin of the left coronary artery.

Цель - выявить варианты строения и внутриорганной топографии устьев венечных артерий у взрослого человека при разных типах кровоснабжения желудочкового комплекса сердца. Материал и методы. На вскрытых через некоронарные синусы аорты 65 препаратах клапанов аорты взрослых людей изучили положение устьев венечных артерий, штангенциркулем измеряли минимальный и максимальный диаметры каждого устья, определяли их форму по соотношению диаметров. Результаты. Для устьев обеих артерий типичной была округлая, реже овальная форма. В большинстве случаев левая венечная артерия начиналась в центральной трети, правая - в центральной или задней трети «своего» синуса на уровне верхнего края полулунной заслонки или между ним и синотубулярным соединением. Локализация устьев в пределах синусов, на уровне синотубулярного соединения или выше него была редкой для обеих артерий. В 20 % случаев в правом синусе аорты спереди от устья правой венечной артерии имелось устье конусной артерии. Выводы. Типичные и редкие варианты формы правого и левого устьев, варианты их положения по вертикальной оси аорты одинаковы, варианты их положения по горизонтали различны. Зависимость вариантов формы и положения устьев от типа кровоснабжения желудочков сердца не выявлена. Objective - to reveal common and rare variants of the anatomy and intraorganic topography of the coronary orifices in normal hearts of adult human with regard to patterns of cardiac ventricular blood supply. Material and methods. On 65 specimens of aortic valves opened through non-coronary sinus, the minimal and maximal diameters of each orifice were measured with a caliper, the shape of the orifices was determined according to the ratio of the diameters, and the position of the orifices was studied. Results. The orifices of both right and left coronary arteries were mostly found to be round, less frequently oval. In most cases, the left coronary artery arose from the central third and the right artery arose from the central or posterior third of corresponding sinus at the level of the upper edge of the semilunar cusp or between the edge and the sinotubular junction. The localization of the arterial orifice within the sinuses at the level of sinotubular junction or above it was uncommon for the both arteries. In 20 % of cases, the conal artery arose with its own orifice in front of the mouth of the right coronary artery. Conclusions. Typical and rare shapes of the coronary orifices, variants of their position regarding to vertical axis of the aorta are the same, whereas variants of their position in horizontal axis are different. There is no relationship between variants of form of the orifices, position of the orifices and types of blood supply of heart ventricles.

A 66-year-old man was admitted to our institute because of chest pain. He had undergone replacement of the ascending aorta due to aortic dissection 9 years previously. We made a diagnosis of acute coronary syndrome, and coronary artery angiography was performed. Although the right coronary artery was successfully cannulated, a severe bend of the artificial aorta made it very difficult to advance the catheter into the left coronary artery. Ultimately, a DIO thrombus aspiration catheter was used to enter the left coronary artery, and a stent was implanted successfully. The DIO catheter is very useful when the selection of a guiding catheter is complicated, such as in the case of severe vessel tortuosity or a bend of the ascending aorta.

An anomalous right coronary artery arising from the pulmonary artery (ARCAPA) is among the least common form of congenital coronary anomalies, accounted for the incidence of only 0.002% in the general population. Most ARCAPA patients have no symptoms but may develop myocardial ischemia. Surgical correction of the anomaly is recommended to prevent subsequent fatal outcomes. Here, we reported a case of a 2-year-old female child initially hospitalized for diarrhea, but later diagnosed with an ARCAPA through echocardiogram and computed tomography. Surgical reimplantation of the right coronary artery from the pulmonary artery to the ascending aorta was performed. The patient recovered well from the surgery with no postoperative complications. In the follow-up assessments, normal coronary function and myocardial effusion were demonstrated.

Abstract Background Transoesophageal echocardiography (TOE) is a safe and useful tool. In our case, we are presenting a rare case of a patient with aortic dissection during TOE procedure. Case summary A 79-year-old woman was referred to our hospital for recurrent paroxysmal atrial fibrillation (AF) with palpitation. Pre-procedural cardiac computed tomography (CT) showed slight dilated ascending aorta (maximum diameter: 40 mm). We decided to perform catheter ablation (CA) for AF, and recommended TOE before the CA because she had a CHADS2 score of 4. On the day before the CA, TOE was performed. Her physical examinations at the time of TOE procedure were unremarkable. At 3 min after probe insertion, there was no abnormal finding of the ascending aorta. At 5 min after the insertion, TOE showed ascending aortic dissection without pericardial effusion. After waking, she had severe back pain and underwent a contrast-enhanced CT. Computed tomography demonstrated Stanford type A aortic dissection extending from the aortic root to the bifurcation of common iliac arteries, and tight stenosis in the right coronary artery (maximum diameter; 49 mm). The patient underwent a replacement of the ascending aorta, and a coronary artery bypass graft surgery for the right coronary artery. Discussion Transoesophageal echocardiography would have to be performed under sufficient sedation with continuous blood pressure monitoring in patients who have risk factors of aortic dissection. The risk–benefit of TOE must be considered before a decision is made. Depending on the situation, another modality instead of TOE might be required.
