SummaryA 37-year-old man with tricuspid atresia, in whom a chronic right apical aspergilloma had stimulated formation of extensive aortopulmonary collateral circulation, suffered reversal of flow within his long-standing fistulous Glenn anastomosis. By reversing the flow through the pulmonary arteriovenous fistula and raising oxygen saturation in the right atrium, the acquired aortopulmonary collateral circulation prevented the increase in cyanosis which usually occurs when fistulous changes develop late after the Glenn operation.

Aim. Study of heart function in the patients with CVD. Materials and methods. 46 patients with varicosity (VD) and 34 patients with post-thrombotic disease (PTD) were examined; the control group was represented by 15 healthy volunteers. The diagnosis was established using the CEAP basic classification. The study did not include patients with a diagnosed arterial hypertension, diabetes mellitus, chronic lung disease, significant hemodynamic heart defects, coronary heart disease. Ultrasound examination of the heart and veins of the lower extremities was performed on a Saote My Lab Alpha, Acuson Sequoia 512 apparatus. In addition to the standard protocol of heart ultrasound examination, the parameters of the right heart were calculated: sizes of the right ventricle (RV), right atrium, thickness of the anterior wall of the pancreas; to assess the ejection fraction (EF) of the pancreas the mobility of the lateral edge of the tricuspid ring was calculated, and the pressure on the tricuspid valve (TV) was measured. Diastolic ventricular function was studied by spectrograms of tricuspid and mitral blood flow. Results. Most of the indicators of cardiac activity in patients with VD were within normal limits, but a tendency to increase increasing of the right heart size was noted. In addition, the thickness of the interventricular septum and the right ventricle (RV) anterior wall was found to increase from 0.8 to 1.1 cm and from 0.3 to 0.5 cm, respectively, according clinical classes from C2 to C6 (CEAP). Eject fraction (EF) of both the RV and the left ventricle (LV) were also within normal limits, but with a tendency to decrease (67.8 % – C2, to 62 % – C6). The growth of the clinical class is followed by the increasing of percentage of non-restrictive blood flow through the tricuspid valve (TV). The restrictive type of blood flow in patients with VD had not been identified. Patients with PTD also showed a tendency to increase the right heart. However, whereas the size of the RV, as a rule, did not exceed 3.0 cm, the size of the right atrium was slightly higher than normal one in the clinical class C4 and C5.6. All the patients had EF of LV within normal limits, but it slightly decreased by the growth of class. Only patient classes C3 and C4 had EF of RV within the normal range. The 18 % of patient class C5.6 had EF lower than normal with value 48%. Diastolic dysfunction (DD) of the RV was detected in 73.3% of patients with class C3 and 100% with classes C4 and C5.6. Moreover, a restrictive type of blood flow through TV appeared from class C4 and the percentage increased up to 27.2% (class C5,6). Conclusions. DD of the RV was the main hemodynamic disorder.

Since the pioneering work of Fontan and Baudet, who suggested that a dysfunctional right ventricle could be bypassed by connecting the pulmonary arteries directly to the right atrium in the so-called atriopulmonary anastomosis, much experience has been gained in the field of the functionally univentricular circulation. In view of the continuing need to optimize the fluid dynamics of the connection, research on this topic remains very active. In particular, it is relevant to consider the power dissipated during flow across a connection of this type, due to the low level of the pressure head available for perfusion. The flow to the lungs in this setting is driven only by the low pressure in the caval veins, thus making it essential to minimize the losses of energy in the connection between the terminal part of the venous system and the pulmonary arteries.

Background: Partial atrioventricular septal defect (P-AVSD) is a common congenital heart disease. Because of the presence of left and right atrioventricular valve deformities and the shift in the atrioventricular node and cardiac conduction bundle, the surgical repair of P-AVSD is difficult. This study was performed to compare the effects on the coronary sinus septum in the left versus the right atrium during surgical treatment for P-AVSD and report our experiences regarding the application of on-pump beating heart surgery under mild hypothermia for patients with P-AVSD.Materials and Methods: The effects of on-pump beating heart surgery were analyzed retrospectively in 87 P-AVSD patients. Of the 87 total patients, 84 with anterior mitral leaflet cleft underwent valvuloplasty and 3 underwent mitral valve replacement. Seventy-seven patients underwent tricuspid valve annuloplasty, 2 underwent tricuspid valve replacement, and 1 underwent left superior vena cava ligation, and 3 patients with atrial fibrillation were treated with radiofrequency ablation. Patients with an ostium primum atrial septal defect underwent autologous pericardial modified Kirklin repair. Of these, 46 patients had their coronary sinus septum separated into the left atrium and 41 had their coronary sinus retained in the right atrium. Fingertip oxygen saturation was compared between patients in whom the coronary sinus was separated to the left atrium and those in whom the coronary sinus was retained in the right atrium.Results: There was 1 postoperative early death (1.15%) due to respiratory failure, and 1 patient had a III degree atrioventricular block (1.15%) and underwent implantation of a permanent pacemaker. The fingertip oxygen saturation levels of the left atrium group were 96.81 ± 3.17 preoperatively, 95.37 ± 4.62 at 7 days postoperatively, and 94.53 ± 4.95 at 3 months postoperatively. Those of the right atrium group were 98.53 ± 2.84 preoperatively, 97.19 ± 3.57 at 7 days postoperatively, and 96.89 ± 4.19 at 3 months postoperatively. During the follow-up period, which ranged from 3 months to 7 years, the cardiac function was adequately restored.Conclusions: On-pump beating heart surgery under mild hypothermia is a safe and feasible method. The retention of the coronary sinus in the right atrium might maintain oxygen saturation.

Abstract Background Pulmonary arteriovenous fistula is a rare disease with a direct connection between the pulmonary artery and the vein, and in most cases is congenital. In a proportion of patients, it can cause hypoxemia, cyanosis and dyspnea. The golden standard for the diagnosis of PAVF is pulmonary angiography. We experienced two cases of a daughter and a mother with PAVF diagnosed by contrast echocardiography, which is simple and sensitive for the detection of pulmonary arteriovenous fistula. Case presentation Case 1:A 22-year-old female was admitted to hospital because of "unconsciousness for 3 hours after sudden seizures".CT showed left frontal cerebral arteriovenous malformation with hemorrhage, a nodule of upper lobe of left lung, arteriovenous malformation possible.Intracranial hematoma removal, arteriovenous malformation resection were performed urgently. Postoperatively, the patient presented severe hypoxemia. Contrast echocardiography showed continuous dense bubbles were visualized in the left heart from the third heart cycle following imaging in the right heart, , suggesting pulmonary arteriovenous fistula. Case 2 : The mother of the first patient, 44-year-old female, with no history of dyspnea, cyanosis,and stroke, was medically screened for suspected pulmonary arteriovenous fistula due to her daughter’s disease. Contrast echocardiography also indicated pulmonary arteriovenous fistula. Conclusions Contrast echocardiography is an excellent tool for the detection of pulmonary arteriovenous fistula. Patients with suspected pulmonary arteriovenous fistula should be examined by chest radiography combined with contrast echocardiography as first line screening tests, especially in patients with severe condition.

A nodular, tumor-like mass attached to the wall of the right atrium and bulging into the lumen was found in three calves. It consisted of cardiac muscle, connective tissue, and communicating blood-filled spaces. There were small thick-walled spaces that communicated with coronary arteries and wide thin-walled spaces that communicated with the atrial lumina. In one calf an anastomosis between both types of spaces was found.

Abstract Clinical case A 53 years woman in good health and un uneventful clinical history except for a mild hypercholesteremia was evaluated for palpitations. At the clinical examination she had a systolic murmur 3/6 Levine, with no signs of heart failure. The ECG showed normal sinus rhythm with a normal heart rate (62bpm), normal atrio-ventricular and intraventricular conduction and normal repolarisation, one supraventricular premature beat. The echocardiography showed normal biventricular dimension and function, no valvular heart diseases, no septal defects, regular aortic dimensions. A giant right coronary was evidenced (Figure, panel a) with an arteriovenous fistula originating from the right coronary artery and draining through the coronary sinus into the right atrium (Figure, panel b). The CT coronary angiogram evidenced an dilated right coronary artery communicating with the coronary sinus (arteriovenous fistula) draining into the right atrium. A smaller arteriovenous fistula was evidenced between the circumflex artery (slightly dilated) and the great cardiac vein. (Figure, panel c-e) The Treadmill test didn’t evidence an induced ischemia; however the patient didn’t perform a maximal exercise (double product 20400mmHb*bpm). Moreover, during the first steps of recovery frequent supraventricular premature beats were registered with phases of bigeminies followed by a junctional rhythm phase. Thus, a Gated myocardial Perfusion SPECT was performed evidenced a mild stress induced ischemia of the inferolateral and apical left ventricle wall with normal rest perfusion and normal left ventricle volumes (125ml during exercise and 134ml at rest) with a normal ejection fraction ( > 65%). (Figure, panel f)An elective coronarography was planned. The patient is on therapy with beta-blockers and aspirin. The patient is asymptomatic for angina. Antibiotic prophylaxis was recommended for dental, gastrointestinal, or urologic procedures. Discussion: Coronary arteriovenous fistula (CAVF), first described in 1865 by Krausein (1), are a rare congenital heart disease representing less than 0.5% of all congenital heart diseases with an extremely rare prevalence 0.002% in the general population (2). Moreover, therapy of CAVF is still controversial with previous data showing a relatively high rate of myocardial infarction after surgical repair (3). The recent AHA/ACC guideline for the management of adults with Congenital heart disease recommend a review by a knowledgeable team that may include congenital or noncongenital cardiologists and surgeons to determine the role of medical therapy and/or percutaneous or surgical closure (4) Conclusion: CAVF is a very rare congenital heart defect and might be asymptomatic and evidenced by hazard in adults patients. Therapy strategy demands a multidisciplinary team evaluation and should be be individualized according to the clinic presentation, the presence or absence of myocardial ischemia or ventricular dysfunction.
