The frequency of coronary artery fistula among all coronary angiography patients is 0.1% to 0.2%; however, involvement of both the pulmonary artery and the right ventricle is a rare clinical entity. A 53-year-old man patient was admitted to our clinic with rarely occurring chest pain, palpitations, and dyspnea. A coronary angiogram showed a fistula between the left main coronary artery and both the pulmonary artery and the right ventricle. We performed a ligation of this fistula without cardiopulmonary bypass. Aorta and right ventricle sutures were made, and the proximal and distal portions of the fistula were obliterated with 5-0 Prolene sutures and previously prepared Teflon felt. The patient recovered and was discharged without any complications. The surgical indications for coronary artery fistulas are symptomatic disease, an aneurysmic coronary artery, signs of heart failure, and ischemia. The surgical options in such cases�depending on whether the fistula is complicated or not�are simple ligation or transarterial ligation under cardiopulmonary bypass.

INTRODUCTION Incidence of congenital heart disease is 25 per thousand live birth in Bangladesh which is much higher than other countries. Tetralogy of Fallot, the commonest cyanotic heart disease (5%) and some other complex diseases with right ventricular outflow tract abnormality demand surgical correction and revision in many occasions including percutaneous intervention. As a resource constraint country, it was a difficult task to introduce percutaneous pulmonary valve implantation (PPVI) with MelodyTM. However, it was started on 12th December 2012 in Combined Military Hospital Dhaka, Bangladesh and cases performed till October 2019 were included in this series. METHODS Retrospective analysis of six cases who had PPVI with MelodyTM in Combined Military Hospital, Bangladesh. Patient with dysfunctional conduit between right ventricle (RV) and pulmonary artery causing (a) Symptoms of exceptional dyspnoea of various grade (NYHA II,III, IV) (b) RVEVD >150 ml/m2 ±regurgitant fraction >40% (c) RVOT peak instantaneous gradient > 30 mm Hg. (d) RV dysfunction (RVEF<40%) were accepted for the procedure and outcome were analyzed. RESULTS Mean age was 9.56 ± 2.96 years, weight was 28.75 ± 8.61 kg, height was 137.5 ± 17.52 cm. Mean age at surgery was 4.25 ± 2.72 years. Female were 66.66%. Aortic homograft was used in 66.66% cases. Eighteen mm Ensemble was used in four (66.66%) cases and 20 mm and 22 mm in one each. Immediate result was excellent with no residual PS in two cases and negligible residual flow acceleration across pulmonary valve in four cases. No PR seen in all except one. One patient developed Bacterial endocarditis after 3 years and was treated. CONCLUSION Aim of PPVI is to prolong the life expectancy of conduits which were placed surgically from right ventricle to pulmonary artery. In our case series, we found that Melody valve is functioning well without any complications like infective endocarditis or stent fracture. KEYWORDS PPVI, MelodyTM, RVOT, Outcome

Abstract Purpose In clinical practice, many patients with right heart failure (RHF) have elevated pulmonary artery pressures and increased afterload on the right ventricle (RV). In this study, we evaluated the feasibility of RV augmentation using a soft robotic right ventricular assist device (SRVAD), in cases of increased RV afterload. Methods In nine Yorkshire swine of 65–80 kg, a pulmonary artery band was placed to cause RHF and maintained in place to simulate an ongoing elevated afterload on the RV. The SRVAD was actuated in synchrony with the ventricle to augment native RV output for up to one hour. Hemodynamic parameters during SRVAD actuation were compared to baseline and RHF levels. Results Median RV cardiac index (CI) was 1.43 (IQR, 1.37–1.80) L/min/m2 and 1.26 (IQR 1.05–1.57) L/min/m2 at first and second baseline. Upon PA banding RV CI fell to a median of 0.79 (IQR 0.63–1.04) L/min/m2. Device actuation improved RV CI to a median of 0.87 (IQR 0.78–1.01), 0.85 (IQR 0.64–1.59) and 1.11 (IQR 0.67–1.48) L/min/m2 at 5 min (p = 0.114), 30 min (p = 0.013) and 60 (p = 0.033) minutes respectively. Statistical GEE analysis showed that lower grade of tricuspid regurgitation at time of RHF (p = 0.046), a lower diastolic pressure at RHF (p = 0.019) and lower mean arterial pressure at RHF (p = 0.024) were significantly associated with higher SRVAD effectiveness. Conclusions Short-term augmentation of RV function using SRVAD is feasible even in cases of elevated RV afterload. Moderate or severe tricuspid regurgitation were associated with reduced device effectiveness.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Chronic thromboembolic pulmonary hypertension (CTEPH) leads to a progressive increase in pulmonary vascular resistance (PVR) and pulmonary artery pressure (PAP) with the development of severe dysfunction of the right heart and heart failure. Mortality for three years with an average pressure in the pulmonary artery (PA) of more than 50 mmHg is more than 90%. Balloon pulmonary angioplasty (BPA) has a significant advantage over other methods of surgical treatment, but it requires the determination of additional non-invasive markers of effectiveness. Transthoracic echocardiography (TTE) remains the main method for assessing the morphology and function of the heart. Purpose Compare different indicators reflecting the severity of CTEPH with TTE indicators before and after BPA. To evaluate the effectiveness of using BPA for the treatment of patients with CTEPH using routine TTE and speckle tracking mode. Materials and methods For 18 months 30 patients without concomitant cardiovascular pathology were subjected to several BPA sessions. Before treatment, 50% of patients belonged to the 3 CTEPH functional class (FC), 40% to 2 FC, 10% to 1 FC. The average number of sessions was 4.7 ± 1.3. Before the first BPA and after the last, all the patients were performed: six-minute walk test (6MWT, metres), Borg scale (in points), test for NT-proBNP (pg/ml); TTE with assessment of the right ventricle (RV) and left ventricle (LV) including areas of the right atrium (aRA, cm2), mean pulmonary artery pressure (PUPM,mmHg),RV free wall strain (GLSFW, %), RV free wall strain rate (GLSRFW, sm/sec), RV free wall postsystolic shortening (PSSFW, %), tricuspid annular plane systolic excursion (TAPSE, sm), tricuspid annulus systolic velocity (TASV, sm/sec). Results. Before the first BPA session, the 6MWT in the patient group averaged 315.9 ± 9.08 metres, after - 439.5 ± 11.45 m; the Borg from 5.4 ± 0.94 points decreased to 4 ± 1.01 points; NT-proBNP before the treatment was 1513 ± 13.01 pg/ml, after - 171 ± 6.09; according to TTE the ratio of RV/ LV before and after treatment was 1.31 ± 0.02 and 0.97 ± 0.04; aRA was 29.3 ± 4.87 and 22.3 ± 3.53 cm2; basal RV - 52 ± 5.11 and 44 ± 7.26 mm; PUPM decreased from 76.6 ± 7.65 to 31.3 ± 3.78 mmHg; GLSFW from -14.69 ± 2.33 came to 17.5 ± 3.45 %; GLSRFW with -0.9 ± 0.09 to -1.7 ± 0.11 cm/sec; TAPSE from 16.7 ± 1.87 to 18.2 ± 2.34 cm; TASV from 10.11 ± 1.45 to 12.25 ± 1.98 cm/s, PSSFW before treatment was -18.4 ± 1.2%, after treatment in 66% of patients disappeared, in 34% became an average of 17.4 ± 0.9% The distribution of STEPH FC has also changed. Conclusion. BPA leads to an improvement in the tolerance of physical activity, clinical indicators, and parameters of central hemodynamics in the pulmonary circulation, evaluated according to direct manometry, and leads to reverse remodeling of the RV in the long term. Performing a staged BPA leads to an improvement in the functional parameters of contractility of the RV.

Abstract A 68-year-old man was admitted to the hospital with complaints of pain in the lumbar spine. He had L5 disc herniation, Spinal stenosis of the L5 root canal - S1 on the right in the past medical history. Percutaneous vertebroplasty at the level of L3 and Th8 vertebral bodies was performed six months ago due to painful vertebral hemangioma. The man is suffering from arterial hypertension, receives antihypertensive therapy. During routine transthoracic echocardiography, a hyperechoic structure with a size of 9.5 x 0.9 cm was found in the right atrium and right ventricle. Chest computed tomography with contrast enhancement revealed signs of bone cement in the right atrium and right ventricle, in the right upper lobe artery, in the branches of the upper lobe artery, in the paravertebral venous plexuses. Considering the duration of the disease, the stable condition, the absence of clinical manifestations and disorders of intracardiac hemodynamics, it was decided to refrain from surgical treatment. Antiplatelet therapy and dynamic observation were recommended. Conclusion Percutaneous vertebroplasty is a modern minimally invasive surgical procedure for the treatment of degenerative-dystrophic diseases of the spine. However, the cement can penetrate into the paravertebral veins and migrate to the right chambers of the heart and the pulmonary artery. This clinical case demonstrates asymptomatic cement embolism of the right chambers of the heart and pulmonary artery after percutaneous vertebroplasty, detected incidentally during routine echocardiography.
