Multi-vessel coronary artery aneurysms in a patient with Parry Romberg syndrome: a case report.

BACKGROUND: Coronary artery aneurysms (CAAs) are a very rare finding on coronary angiograms with multiple known aetiologies. Parry Romberg syndrome (PRS) is also a very rare disease, and the underlying aetiology remains unknown. We present a rare case of CAAs in a patient with PRS, and discuss possible implications regarding the primary pathophysiological cause for both of these diseases. CASE SUMMARY: A 48-year-old woman with a history of PRS presented with atypical and non-exertional chest pain. Initial evaluation demonstrated a rising troponin without associated electrocardiogram changes, and as such she was taken for left heart catheterization. Left heart catheterization demonstrated diffuse aneurysmal and ectatic disease of multiple coronary arteries. Further evaluation with magnetic resonance angiogram and autoantibody panel did not demonstrate other vascular anomalies or rheumatologic disease, respectively. She was treated with dual anti-platelet therapy and statin, and at 1 year follow-up, she had resolution of her symptoms. DISCUSSION: It has been postulated that the underlying mechanism causing CAA is intravascular inflammation. Parry Romberg syndrome is theorized to be a neurovasculopathy, as evidenced by cases of associated intracranial aneurysms. Intravascular inflammation may play a key pathological role in CAA, and an association between CAA and PRS may exist.

Cost conscious care: preoperative evaluation by a cardiologist prior to low-risk procedures.

Background: Preoperative testing before low-risk procedures remains overutilised. Few studies have looked at factors leading to increased testing. We hypothesised that consultation to a cardiologist prior to a low-risk procedure leads to increased cardiac testing. Methods and results: 907 consecutive patients who underwent inpatient endoscopy/colonoscopy at a single academic centre were identified. Of those patients, 79 patients (8.7%) received preoperative consultation from a board certified cardiologist. 158 control patients who did not receive consultation from a cardiologist were matched by age and gender. Clinical and financial data were obtained from chart review and hospital billing. Logistic and linear regression models were constructed to compare the groups. Patients evaluated by a cardiologist were more likely to receive preoperative testing than patients who did not undergo evaluation with a cardiologist (OR 47.5, (95% CI 6.49 to 347.65). Specifically, patients seen by a cardiologist received more echocardiograms (60.8% vs 22.2%, p<0.0001) and 12-lead electrocardiograms (98.7% vs 54.4%, p<0.0001). There was a higher rate of ischaemic evaluations in the group evaluated by a cardiologist, but those differences did not achieve statistical significance. Testing led to longer length of stay (4.35 vs 3.46 days, p=0.0032) in the cohort evaluated by a cardiologist driven primarily by delay to procedure of 0.76 days (3.14 vs 2.38 days, p=0.001). Estimated costs resulting from the longer length of stay and increased testing was $10 624 per patient. There were zero major adverse cardiac events in either group. Conclusion: Preoperative consultation to a cardiologist before a low-risk procedure is associated with more preoperative testing. This preoperative testing increases length of stay and cost without affecting outcomes.

Delayed Development of Coronary Ostial Stenosis following Surgical Aortic Valve Replacement: A Case Report of Unusual Presentation.

Coronary ostial stenosis is a rare but potentially life-threatening complication that occurs in 1%-5% of patients who undergo surgical aortic valve replacement (SAVR). Symptoms typically appear within the first 6 months and almost always within a year after SAVR. We report an unusually delayed presentation of non-ST segment elevation myocardial infarction due to coronary ostial stenosis 22 months after SAVR. A 71-year-old woman underwent uncomplicated SAVR with a bioprosthetic valve in August 2015 for severe aortic stenosis. A preoperative coronary angiogram demonstrated widely patent left and right coronary arteries. In June 2017, the patient presented to the hospital with chest pain. An electrocardiogram demonstrated 1 mm ST segment depression in the anterolateral leads, and serum troponin I level was elevated to 2.3 ng/ml. Diagnostic coronary angiography revealed severe ostial stenosis (99%) of the right coronary artery. A bare-metal stent was successfully placed with an excellent angiographic result, and the patient was asymptomatic at 4 months of follow-up after the procedure. As seen in our case, coronary ostial stenosis should be considered in the differential diagnosis of chest pain or arrhythmia in patients presenting with a history of SAVR, even if the procedure was performed more than 1 year prior to presentation.

Unrepaired tetralogy of fallot with major aortopulmonary collateral arteries in an adult patient.

Tetralogy of Fallot is characterized by a ventricular septal defect, a large, overriding aorta, subpulmonic stenosis, and right ventricular hypertrophy. These lesions can be associated with abnormal development of the pulmonary vasculature. This can include peripheral pulmonic stenosis, discontinuous pulmonary arteries, anomalous pulmonary venous return, and the development of aortopulmonary collateral vessels. Aortopulmonary collateral vessels develop to supply underperfused areas of the pulmonary bed and pose a unique and challenging problem at the time of surgical repair, which involves closure of the ventricular septal defect, relief of right ventricular outflow tract obstruction, maintenance of pulmonary valve competency when possible, and establishment of laminar pulmonary blood flow to all segments of the pulmonary bed. We describe a 36-year-old man with unrepaired tetralogy of Fallot with distinctive aortopulmonary collaterals, who underwent complete surgical repair with good outcome. Two-dimensional echocardiogram, cardiac magnetic resonance imaging, and cardiac catheterization each provided vital details allowing a stepwise approach to defining his unique anatomy for surgical correction.

Routine invasive versus conservative management strategies in acute coronary syndrome: time for a "hybrid" approach.

The acute coronary syndrome is most often caused by plaque rupture and can result in a variety of clinical conditions. There are two general strategies (early invasive versus conservative) currently employed in the treatment of unstable angina or non-ST elevation myocardial infarction. Pooled data from recent clinical trials have demonstrated that high-risk patients benefit from a routine or early invasive approach while certain low-risk subgroups have similar outcomes with a conservative approach. Most patients in the USA are treated aggressively given advances in technology and the relative ease of interventional therapy. The routine invasive approach, however, remains controversial and has important limitations that are not well identified in trials. Furthermore, data from trials are difficult to interpret given their relevance to contemporary practice in today's cost conscious, health care environment. The decision to pursue an invasive or conservative approach should be based upon an individual patient's risk profile, and the level of medical therapy should be based on the underlying pathophysiology. The best strategy incorporates aggressive anti-atherosclerotic therapy with early risk stratification and invasive therapy when appropriate-the so-called hybrid approach. Identifying plaque rupture helps identify patients that would benefit from potent antiplatelet, antithrombotic, and anti-inflammatory therapies, and further insight into the natural history of coronary artery disease coupled with continued advances in diagnostic and interventional approaches will hopefully help guide long-term primary and secondary management.

Maternal arrhythmia: a case report and review of the literature.

UNLABELLED: Pregnant patients with maternal arrhythmias can be challenging and difficult to treat. Medication choices may be limited in patients who are pregnant. Pregnancy carries with it a unique and complex physiology, coupled with fetal concerns. We describe a pregnant patient with an arrhythmia to illustrate treatment thought process and options. We also present a comprehensive review of the literature in regard to treatment of maternal arrhythmias and their potential adverse fetal and maternal outcomes. These treatments include antiarrhythmic medications, electrical cardioversion, and radiofrequency ablation. Antepartum and intrapartum monitoring will also be addressed along with delivery planning and postpartum considerations. The most important aspect in treating these patients is the use of a multidisciplinary approach. The decision of what therapy to use must be addressed on a case-by-case basis with special attention to the patient's individual issues and concerns. TARGET AUDIENCE: Obstetricians and gynecologists, family physicians, emergency room physicians LEARNING OBJECTIVES: After completion of this educational activity, the obstetrician/gynecologist should be better able to assess and council patients on the risks and complications of maternal arrhythmias in pregnancy. Evaluate the current treatment options available for health care providers caring for pregnant patients with maternal arrhythmia, and manage the antepartum course, labor, and delivery in these patients.
