Plasma microRNAs are associated with atrial fibrillation and change after catheter ablation (the miRhythm study). - Heart rhythm : the official journal of the Heart Rhythm Society
MicroRNAs (miRNAs) are associated with cardiovascular disease and control gene expression and are detectable in the circulation.The purpose of this study was to test the hypothesis that circulating miRNAs may be associated with atrial fibrillation (AF).Using a prospective study design powered to detect subtle differences in miRNAs, we quantified plasma expression of 86 miRNAs by high-throughput quantitative reverse transcriptase-polymerase chain reaction in 112 participants with AF and 99 without AF. To examine parallels between cardiac and plasma miRNA profiles, we quantified atrial tissue and plasma miRNA expression using quantitative reverse transcriptase-polymerase chain reaction in 31 participants undergoing surgery. We also explored the hypothesis that lower AF burden after ablation would be reflected in the circulating blood pool by examining change in plasma miRNAs after AF ablation (n = 47).Mean age of the cohort was 59 years; 58% of participants were men. Plasma miRs-21 and 150 were 2-fold lower in participants with AF than in those without AF after adjustment (P ≤.0006). Plasma levels of miRs-21 and 150 also were lower in participants with paroxysmal AF than in those with persistent AF (P <.05). Expression of miR-21, but not of miR-150, was lower in atrial tissue from patients with AF than in those without AF (P <.05). Plasma levels of miRs-21 and 150 increased 3-fold after AF ablation (P ≤.0006).Cardiac miRs-21 and 150 are known to regulate genes implicated in atrial remodeling. Our findings show associations between plasma miRs-21 and 150 and AF, suggesting that circulating miRNAs can provide insights into cardiac gene regulation.Copyright © 2015 Heart Rhythm Society.

Quadricuspid aortic valve with aortic insufficiency: case report and review of the literature. - Journal of cardiac surgery
We report the case of a 42-year-old woman with aortic regurgitation discovered to be caused by a quadricuspid aortic valve (QAV) diagnosed by intraoperative transesophageal echocardiogram. With improvements in echocardiographic imaging, the diagnosis of QAV is likely to be made more reliably in the future and should prompt close clinical follow-up given the frequent association of this lesion with valvular insufficiency.
Thoracic Surgery Directors Association Award. What is the optimal management of late-presenting survivors of acute type A aortic dissection? - The Annals of thoracic surgery
Although type A aortic dissections represent a surgical emergency, some patients present late after the onset of symptoms. Optimal management of this cohort has not been defined.Data on 195 patients with type A dissections followed up at a single institution between 1985 and 2005 were collected prospectively. Of these, 93 patients (47.2%) presented 48 hours or later after the initial onset of pain (group A), and the remaining 102 patients underwent immediate operative repair (group B). Median follow-up was 41.8 months (range, 0 to 386 months).Patients in group A were older (68.8 versus 59.3 years, p = 0.0005) and had a higher incidence of coronary artery disease (42.5% versus 14.6%, p < 0.0001), pulmonary disease (26.6% versus 8.4%, p = 0.0023), and congestive heart failure (14.1% versus 1.0%, p = 0.0004). Long-term survival was similar, although group B showed a trend toward improved 30-day mortality (16.5% versus 8.7%, p = 0.1035). Of the 92 patients in group A, 53 (57.6%) eventually underwent operative repair a median of 8.2 days after symptom onset. There was a trend toward improved long-term survival among patients undergoing repair (p = 0.1031).Initial medical management with interval operative repair of selected patients referred greater than 2 days following an acute type A dissection is a viable option. Delayed repair after optimization of the clinical condition and detailed evaluation of concomitant diseases results in excellent long-term results.
Natural history of ascending aortic aneurysms in the setting of an unreplaced bicuspid aortic valve. - The Annals of thoracic surgery
Patients with bicuspid aortic valve (BAV) are at risk for valvular disease and ascending aortic aneurysms and dissections. Although others have investigated the need for concomitant repair, the natural history of aortic disease has not been addressed.A review of our institutional clinical database identified 514 patients (326 male, 188 female) with unrepaired ascending aortic aneurysms followed from 1985 to 2005. Seventy patients (13.4%) diagnosed with BAV form group A; the remaining 445 patients form group B. Growth rates and risk factors for complications were assessed.Patients in group A had a lower incidence of hypertension (p = 0.0185), carotid artery disease, and stroke (p = 0.0184), and presented at an earlier age (49.0 versus 64.2 years, p < 0.0001). Group A also had a higher rate of aortic growth (0.19 versus 0.13 cm/year, p = 0.0102). The incidence of rupture and dissection were similar. Overall survival was better among patients with BAV (p < 0.0001). Among patients with BAV, those with aortic stenosis had a higher risk of rupture, dissection, or death before operative repair than did those with normally functioning valves (odds ratio 10.475, 95% confidence interval: 1.153 to 95.155).Aortic stenosis presents a significant added risk for patients with aneurysmal disease in the face of BAV. Despite faster rates of growth, however, patients with BAV have similar rates of aortic rupture, dissection, and death and improved long-term survival. Contributing to this finding may be the lower incidence of comorbidities, the younger age at presentation, and the more attentive follow-up with earlier operative repair.
Alternate technique for implantation of left ventricular assist system: left thoracotomy for reoperative cases. - The Annals of thoracic surgery
Reoperation for Novacor left ventricular assist device placement after prior cardiac surgery is fraught with multiple technical challenges. We have found that a thoracotomy approach obviates these dangers very favorably. The technique is performed off bypass except for apical coring and apical connection. Novacor outflow is to the descending aorta. This approach has been found safe, quick, and effective.
