The effect of total cardiac denervation on the distribution of cardiac immunoreactive vasoactive intestinal peptide (IR-VIP) was determined in four groups of dogs. Denervated dogs killed at either 7 days (group 1) or 30 days (group 3) were compared with sham-operated dogs killed at either 7 days (group 2) or 30 days (group 4). The highest concentrations of IR-VIP were found in the left atrium and proximal left anterior descending and circumflex coronary arteries and were not affected by denervation. Concentrations of IR-VIP in the left ventricle were barely detectable. Only right ventricular IR-VIP concentrations were significantly lower in denervated compared with sham-operated dogs in both groups. Thus these data provide evidence of intrinsic VIP innervation of the atria and epicardial coronary arteries and localized extrinsic VIP innervation of the right ventricle of the canine heart.

Abstract We report a case of a three months old baby, with no history of heart disease, referred to our center for cardiological screening. EKG was normal and a physiologic 1/6 systolic murmur was present. Conversely, echocardiography revealed a thin-walled, echo-free cystic intrapericardic structure adjacent to the posterior wall of the left ventricle; no signs of compression on cardiac structures were evident. CAT scan confirmed the presence of echo-free cystic over-diaphragmatic structure at the crux cordis level. The cyst was described as located between visceral pericardial layer and muscolar ventricular wall and appeared to cause compression on the midbasal wall of the left ventricle, of the interventricular septum and less extensively on the right ventricle. The dimension of the cyst was 2.7x2.5x1.8 cm. Worthy of note, posterior interventricular and posterolateral coronary arteries were very close to the cyst and partially pushed apart one from the other by the mass. Eight months after the diagnosis we detected an increase in mass size, confirmed also by cardiac MRI showing a mass of 4.5x3.4x3 cm with an extimated volume of 23 cm2. Because of significant increase of dimension of the cyst we decided for surgical excision of the mass. The cyst contained clear and translucent fluid and was successfully removed. Pleuropericardial window was created to prevent pericardial effusion. Histopathological report suggested the diagnosis of bronchogenic cyst because of the presence of smooth muscle. Bronchogenic cyst are closed epithelial-lined sacs developed from the respiratory system as the result of an abnormal budding process during the early development of the foregut. These congenital malformations are usually located in the mediastinum or in the lung parenchyma, but atypical locations such as neck, intramedullary part of the spine, diaphragm or intraabdominal region have been reported. Only a few cases occurring in the heart have been described, but their location in the left ventricle is extremely rare. Bronchogenic cyst are usually asymptomatic: symptoms are related to the interaction with the adjacent structures and therefore depend on the dimensions and the localization of the mass. Surgical approach is mandatory if a complication occurs. Conversely there is not a unique approach for asymptomatic mass as in our case. The young age of the baby and the absence of symptoms argued in favor of a "watchful waiting" strategy. Nevertheless, the particular localization of the cyst at the crux cordis level, its relatively rapid growth and above all the evidence of a close relationship with the coronary arteries, suggesting a concrete risk of compression with further enlargement, were determinant for the final decision for surgical excision.

We report a case of a malignant course of left main coronary artery in a patient presenting with sudden onset chest pain and shortness of breath. The patient is a 44-year-old African American male with a past medical history of hypertension, diabetes mellitus type 2 as well as dyslipidemia presented to the emergency department with non-exertional chest pain radiating to the left arm and shortness of breath. A coronary angiography and CT angiography (CTA) of heart was performed and it demonstrated an aberrant malignant course of the left main coronary artery coming from the right coronary ostium and coursing between the aorta and pulmonary artery. The left ventricular dysfunction was thought to be a consequence of this malignant course. Cardiothoracic surgery was consulted which determined the need for CABG. The incidence of coronary anomalies and patterns in a series of 1,950 angiograms was determined to be 5.64% with the left main coronary artery (LMCA) arising from the right sinus in 0.15% of the angiograms Diagnostic approach for malignant coronary arteries involves coronary angiography and cardiac CT. A widely accepted treatment approach for left main coronary arteries originating from the right sinus is through surgical repair. Our case urges the clinician to expand the differential diagnosis in young to middle age patient presenting with chest pain. In addition, our case reinforces the concept of the detrimental impact of malignant left coronary arteries on cardiac function. This should prompt the physician to consider coronary anomalies as a possible differential diagnosis as part of the evaluation and management of these patients.

Összefoglaló. Bevezetés: Congenitalis coronariaanomáliának tekintik azokat a coronariamorfológiai rendellenességeket, melyek 1%-nál kisebb gyakorisággal fordulnak elő. Többségük nem jár tünettel, olykor azonban okozhatnak mellkasi fájdalmat, eszméletvesztést, és hirtelen halálhoz is vezethetnek. A coronariaanomáliák gyakoriságáról Magyarországon eddig csak invazív koronarográfiás adatok alapján jelent meg közlemény. Célkitűzés: Jelen vizsgálatunkban a coronariák eredési rendellenességeinek gyakoriságát mértük fel intézetünk coronaria-komputertomográfiás angiográfián átesett betegeinél. Módszer: A coronaria-komputertomográfiás vizsgálatra került betegek felvételeinek értékelésekor rögzítettük a coronariaanomália jelenlétét. A vizsgálat indikációja általában mellkasi fájdalom volt. 128 szeletes berendezést használtunk, a vizsgálatok során részben retrospektív, részben prospektív EKG-kapuzást alkalmaztunk. Eredmények: 1751 beteg komputertomográfiás angiográfiás felvételeit elemeztük. A betegek között a férfiak aránya 38,4%, a vizsgálatra kerülők életkorának átlaga pedig 58,07 ± 11,07 év volt. Eredési anomáliát 1,83%-ban találtunk, ezen belül a leggyakoribb volt a körbefutó ág (ramus circumflexus) és az elülső leszálló ág különálló eredése a bal Valsalva-sinusból (1%). A további rendellenességek a következők voltak: a jobb coronaria eredése magasan az aortából (0,34%), ramus circumflexus a jobb sinusból vagy a jobb coronariából (0,34%), jobb coronaria a bal Valsalva-sinusból (0,057%), elülső leszálló ág részben a bal Valsalva-sinusból a circumflexustól külön, részben a jobb coronariából (kettős elülső leszálló ág, 0,057%). Következtetés: Mindössze 0,057%-ban fordult elő potenciálisan tünetet okozó coronariaeredési rendellenesség (a bal sinusból eredő jobb coronaria). A komputertomográfiás angiográfia segítségével a coronariaeredés helye pontosan megállapítható, tisztázható az ér lefutása és ennek során viszonya a környező struktúrákhoz. Orv Hetil. 2020; 161(47): 1995–1999. Summary. Introduction: Congenital coronary artery anomaly is defined as a coronary morphology which occurs in less than 1% of the cases. Usually these anomalies do not result in symptoms but sometimes they can cause chest pain, syncope and sudden death. In Hungary, the prevalence of these abnormalities was published only from data of invasive coronary angiography. Objective: In this study, we evaluated the prevalence of the anomalies of coronary origin in the patients of our institution undergoing coronary computed tomography. Method: While reading the computed tomography angiograms of our patients, we registered the presence of coronary anomalies. In most of the cases, the indication of the coronary computed tomography was chest pain. A scanner with 128 detectors was used, scans were performed partly with prospective, partly with retrospective ECG gating. Results: We assessed 1751 patients. The ratio of males was 38.4%, while the average age of patients 58.07 ± 11.07 years. Anomaly of coronary origin was present in 1.83% of our patients, with the separate origin of left anterior descending and left circumflex artery being the most frequent (1%) among them. Other anomalies were as follows: high take-off of the right coronary artery from the ascending aorta (0.34%), left circumflex arising from the right sinus of Valsalva or from the right coronary (0.34%), right coronary artery from the left sinus of Valsalva (0.057%), left anterior descending arising partly from the left sinus of Valsalva, apart from the left circumflex, partly from the right coronary (dual left anterior descending artery, 0.057%). Conclusion: The prevalence of potentially symptomatic coronary anomalies was only 0.057% in our series (right coronary from the left sinus of Valsalva). The computed tomography angiography can precisely define the origin of the coronary artery, depict its run-off and its relationship to the neighbouring structures.

Acute myocardial infarction (AMI) resulting in cardiogenic shock continues to be a substantial source of morbidity and mortality despite advances in recognition and treatment. Prior to the advent of percutaneous and more durable left ventricular support devices, prompt revascularization with the addition of vasopressors and inotropes were the standard of care in the management of this critical population. Recent published studies have shown that in addition to prompt revascularization, unloading of the left ventricle with the placement of the Impella percutaneous axillary flow pump can lead to improvement in mortality. Parameters such as the cardiac power output (CPO) and pulmonary artery pulsatility index (PAPi), obtained through pulmonary artery catheterization, can help ascertain the productivity of right and left ventricular function. Utilization of these parameters can provide the information necessary to escalate support to the right ventricle with the insertion of an Impella RP or the left ventricle with the insertion of larger devices, which provide more forward flow. Herein, we present a case of AMI complicated by cardiogenic shock resulting in biventricular failure treated with the percutaneous insertion of an Impella RP and Impella 5.0 utilizing invasive markers of left and right ventricular function to guide the management and escalation of care.
