AbstractPercutaneous pulmonary valve placement in patients with an anomalous coronary artery is rare and can be complicated by coronary artery compression. We report successful implantation of a percutaneous pulmonary valve in a patient with an anomalous left anterior descending artery.

AbstractCoronary artery compression is a rare and potentially fatal complication after percutaneous pulmonary valve implantation. We report on a case of an acute antero-septal non-ST myocardial infarction secondary to the partial laceration of the conduit and the creation of a thrombus giving an extrinsic compression of left anterior descendent coronary artery after Melody valve implantation.

Experience with cardiac magnetic resonance to evaluate coronary arteries in children and young adult patients is limited. Because noninvasive imaging has advantages over coronary angiography, we compared the effectiveness of these techniques in patients who were being considered for percutaneous pulmonary valve implantation. We retrospectively reviewed the cases of 26 patients (mean age, 12.53 ± 4.85 yr; range, 5–25 yr), all of whom had previous right ventricular-to-pulmonary artery homografts. We studied T2-prepared whole-heart images for coronary anatomy, velocity-encoded cine images for ventricular morphology, and function- and time-resolved magnetic resonance angiographic findings. Cardiac catheterization studies included coronary angiography, balloon compression testing, right ventricular outflow tract, and pulmonary artery anatomy. Diagnostic-quality images were obtained in 24 patients (92%), 13 of whom were considered suitable candidates for valve implantation. Two patients (8%) had abnormal coronary artery anatomy that placed them at high risk of coronary artery compression during surgery. Twelve patients underwent successful valve implantation after cardiac magnetic resonance images and catheterization showed no increased risk of compression. We attempted valve implantation in one patient with unsuitable anatomy but ultimately placed a stent in the homograft. Magnetic resonance imaging of coronary arteries is an important noninvasive study that may identify patients who are at high risk of coronary artery compression during percutaneous pulmonary valve implantation, and it may reveal high-risk anatomic variants that can be missed during cardiac catheterization.

AbstractOne of the major obstacles preventing successful percutaneous pulmonary valve implantation (PPVI) is related to the close proximity of coronary artery branches to the expected landing zone. The aim of this study was to assess the frequency of coronary artery anomalies (CAAs) especially those associated with major coronary branches crossing the right ventricular outflow tract (RVOT) and to describe their relevance for the feasibility of percutaneous pulmonary valve implantation (PPVI). In our retrospective single-center study 90 patients were evaluated who underwent invasive testing for PPVI in our institution from 1/2010 to 1/2020. CAAs were identified in seven patients (8%) associated with major branches crossing the RVOT due to origin of the left anterior descending (LAD) or a single coronary artery from the right aortic sinus. In 5/7 patients with CAAs balloon testing of the RVOT and selective coronary angiographies revealed a sufficiently large landing zone distal to the coronary artery branch. While unfavorable RVOT dimensions prevented PPVI in one, PPVI was performed successfully in the remaining four patients. The relatively short landing zone required application of the “folded” melody technique in two patients. All patients are doing well (mean follow-up 3 years). CAAs associated with major coronary branches crossing the RVOT can be expected in about 8% of patients who are potential candidates for PPVI. Since the LAD crossed the RVOT below the plane of the pulmonary valve successful distal implantation of the valve was possible in 4/7 patients. Therefore these coronary anomalies should not be considered as primary contraindications for PPVI.

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
