The results of the examination and treatment of a patient with frequent ventricular ectopy are presented in the article. During ablation of an ectopic focus in the left coronary sinus of the aorta, as a result of dislocation of the ablation catheter, a spasm of the left coronary artery has been diagnosed.

The results of the examination and treatment of a patient with frequent ventricular ectopy are presented in the article. During ablation of an ectopic focus in the left coronary sinus of the aorta, as a result of dislocation of the ablation catheter, a spasm of the left coronary artery has been diagnosed and successfully managed.

Congenital coronary artery fistula is an extremely rare anomaly that may involve any of the coronary arteries and any of the cardiac chambers. We report the case of a 14-year-old female patient with a symptomatic congenital coronary fistula starting from the left main coronary artery and draining to the coronary sinus. The patient underwent surgical ligation of the fistula and had an excellent outcome.

The ability to create experimental myocardial infarctions of reproducible size and location is tantamount to progress in multiple facets of ischemic heart disease research. Branches of the mouse left main descending coronary artery penetrate the myocardium close to their origin and require “blind” ligation. Our objective was to develop a technique for ligation of nonvisible coronary artery branches to permit the reliable creation of infarcts of uniformly small size and location. From latex castings of the left coronary artery of C57BL/6J mice ( n = 53), we calculated the highest probability for the location of branch points of two of three left ventricular (LV) branches distal to the origin of the left main descending artery. On the basis of these anatomic probabilities, we blindly ligated two areas that were likely to be locations of these nonvisible LV branches. We were successful in producing two types of small transmural myocardial infarctions (16.04 ± 3.64 and 4.68 ± 1.47% of the LV) in 57% of attempts. Thus our branch pattern probability-assisted method permits routine creation of small infarcts of uniform size in the mouse.

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.

AbstractThe occurrence of super-dominant “single coronary artery” is an extremely rare and seldom reported phenomenon. The heart is dependent on a single vessel which makes its occlusion, if present, catastrophic. Here, the authors present an extremely rare combination of superdominant right coronary artery coexisting with absent left coronary artery and left circumflex artery with abnormal origin of left anterior descending artery from right coronary sinus. Precise morphological and physiological knowledge and evaluation of these anomalies is a must for opting the best available therapeutic modality and better prognosis.

AbstractWe report the case of a child with severe and atypical stenosis of the left main coronary artery, which occurred late after arterial switch operation for transposition of the great arteries. Cardiac computed tomography accurately defined the lesion, showing the presence of post-stenotic dilation, guided the surgical approach and assessed coronary patency after revascularisation surgery.
