REVIEW
Brian A Scansen
There remain areas of uncertainty in optimal technique, preferred candidates, and expected outcome for small animal patients undergoing cardiac intervention. This article highlights issues within interventional cardiology that are in need of study and offers the author's opinion and experience on topics such as variants of pulmonary valve anatomy and alternatives to conventional balloon dilation for pulmonary valve stenosis, patient selection for cutting or high-pressure balloon dilation of aortic valvar or subaortic stenosis, occlusion of patent ductus arteriosus in very small dogs, ductal stenting in conditions with reduced pulmonary blood flow, and alternative considerations for vascular access and closure...

BACKGROUND: Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital coronary anomaly. The enlarged right coronary artery provides retrograde collaterals to supply the left ventricle then preferentially directs into the lower pressure pulmonary artery system causing coronary steal phenomenon. Few patients who survive through adulthood without surgery must have abundant, well-formed functioning collaterals with adequate perfusion of the left ventricle...

Cor-triatriatum is uncommon and cor-triatriatum dexter is rarer, and patients may remain asymptomatic in isolated cases especially if the partitioning is mild and nonobstructing. There may be other cardiac defects associated with it which are mostly right-sided cardiac defects such as atrial septal defect, Ebstein anomaly, and pulmonary stenosis. However, left-sided heart anomaly such as aortic regurgitation has been associated with it, but its association with transposition of the great vessels has not been documented before now...

Myocardial non-compaction (NC) is a rare genetic cardiomyopathy commonly believed to develop an intrauterine arrest of endomyocardial morphogenesis. NC is characterized by markedly hypertrabeculations in left ventricle or both ventricles with deep intertrabecular recesses. NC is usually seen isolated, but sometimes other congenital heart abnormalities may accompany to the myocardial NC. In this article we have presented an adult patient with biventricular myocardial NC cardiomyopathy accompanied by severe valvular pulmonary stenosis and patent foramen ovale...

BACKGROUND: Antithrombotic treatment regimen following transcatheter aortic valve replacement (TAVR) is not evidence-based. Apixaban, a non-vitamin K direct anticoagulant (NOAC) was shown to be superior to VKA and superior to aspirin to prevent cardioembolic stroke in non-valvular atrial fibrillation. It may have the potential to reduce TAVR-related thrombotic complications including subclinical valve thrombosis along with a better safety than the standard of care. DESIGN: ATLANTIS is a multicenter, randomized, phase IIIb, prospective, open-label, superiority study comparing standard of care (SOC Group) versus an apixaban-based strategy (Anti-Xa Group) after successful TAVR (ClinicalTrials...

PURPOSE: Stereotactic body radiation therapy (SBRT) and heat-based ablation (HBA) are both potentially safe and effective treatments for primary and metastatic lung tumors. Both are suboptimal for centrally located tumors, with SBRT having a higher risk of significant toxicity and HBA having lower efficacy. This study evaluates the safety and efficacy of combination SBRT-HBA to determine whether combined treatment can result in superior outcomes to each treatment alone. METHODS AND MATERIALS: Patients with 1 or 2 primary or metastatic lung tumors ≤ 5 cm in size were enrolled in a prospective phase 2 trial and treated with SBRT in 3 fractions followed by HBA...

OBJECTIVES: Granulomatosis with polyangiitis-a primary systemic vasculitis-most frequent manifestations are respiratory. Airway disease can present with stenosis, and although subglottic stenosis (SGS) is well described, narrowing distal to the glottis has been more recently the focus of reporting. Our objectives, therefore, are to describe the frequency, characteristics, and treatment of tracheobronchial stenoses (TBS) in granulomatosis with polyangiitis (GPA) at our institution, a national referral center for respiratory diseases...

A combination of hypoplasia of the left side of the heart, a hypoplastic aortic arch, a large patent ductus arteriosus, and valvular pulmonary stenosis is very rare. The severity of the valvular pulmonary stenosis in this setting is difficult to judge preoperatively. Here, we describe a newborn with borderline hypoplasia of the left side of the heart, a hypoplastic aortic arch, a large patent ductus arteriosus, and valvular pulmonary stenosis, who underwent the Norwood procedure successfully. The purpose of this report is to share the perioperative course of the patient and our decision-making process that was not straightforward...

As the primary treatment of aortic valve stenosis in children, surgical aortic valvotomy (SAV) and balloon aortic valvuloplasty (BAV) are widely used. With the similar early curative effect to BAV, SAV performs better in long-term follow-up. But the first choice for aortic valve stenosis is still controversial. These years, aortic valve repair is valued and different repair techniques have been reported and achieved good results. The complex repair techniques, as leaflet extension, leaflet replacement or valve reconstruction, are effective in treating diseased valves that cannot be repaired before...

Pulmonary artery (PA) stenosis is the most common late sequela following arterial switch for d-transposition of the great arteries. The purpose of this study was to assess the effectiveness of transthoracic echocardiography in evaluating the pulmonary arteries following repair. This was a retrospective, cross-sectional analysis of all echocardiograms performed on patients following arterial switch operation. A numerical scoring system was devised and used to quantify PA visualization based on 2D images, color mapping, and spectral Doppler...

Aims: The assumption of equivalence between right ventricular and pulmonary arterial systolic pressure is fundamental to several assessments of right ventricular or pulmonary vascular hemodynamic function. Our aims were to 1) determine whether systolic pressure gradients develop across the right ventricular outflow tract in healthy adults during exercise, 2) examine the potential correlates of such gradients, and 3) consider the effect of such gradients on calculated indices of right ventricular function...

Coronary artery fistula (CAF) is a rare, abnormal connection between one or more coronary arteries and a cardiac chamber, or great vessel.We describe the case of a male patient with worsening effort angina referred for coronary angiography. The examination revealed the presence of a CAF between the proximal left anterior descending (LAD) and pulmonary arteries, with mid LAD subocclusive stenosis. Ad hoc PCI with stenting was performed in the mid LAD, followed by CAF embolization with coils and plugs. Angiography and computed tomography scan at follow-up showed complete CAF occlusion, stent patency, and normal flow reserve of the LAD...
