Outcomes of a hybrid approach of percutaneous coronary intervention followed by minimally invasive aortic valve replacement.

BACKGROUND: In patients requiring coronary revascularization and aortic valve replacement, a combined approach of percutaneous coronary intervention followed by minimally invasive aortic valve replacement may be a viable treatment strategy. METHODS: The outcomes of 123 consecutive patients with significant coronary artery and aortic valve disease, who underwent percutaneous coronary intervention followed by elective minimally invasive aortic valve replacement between February 2009 and April 2014, were retrospectively evaluated. RESULTS: The cohort consisted of 80 males and 43 females, with a mean age of 75.7±8.1 years. Drug-eluting stents were used in 69.9% of the patients, and 64.2% were on dual anti-platelet therapy at the time of aortic valve replacement. Within a median of 39 days (IQR 21-64), 83.7% of the patients underwent primary and 16.3% underwent re-operative minimally invasive aortic valve replacement. Post-operatively, there was 1 (0.8%) cerebrovascular accident, 1 patient (0.8%) required a re-operation due to bleeding, and 2 (1.6%) developed acute kidney injury. Thirty-day mortality occurred in 2 (1.6%) patients. Follow-up was available for all of the patients, and at a mean follow-up period of 14.3±12.5 months, 4 (3.3%) had an acute coronary syndrome, and 1 (0.8%) required a repeat target vessel revascularization. The actuarial survival rate at 1- and 3-year was 92.7% and 89.4%, respectively. CONCLUSIONS: In a select group of patients with coronary artery and aortic valve disease, a combined approach of percutaneous coronary intervention followed by minimally invasive aortic valve replacement can be safely performed with excellent short-term and midterm outcomes.

Interesting images: Multiple coronary artery aneurysms.

We present the case of a 65-year-old male who presented with stable angina and dyspnea on exertion. His initial workup yielded a positive treadmill stress test for reversible apical ischemia, and transthoracic echocardiogram demonstrated impaired systolic function. Cardiac catheterization was then performed, revealing severe atherosclerotic disease including multiple coronary artery aneurysms. As a result, the patient was advised to and subsequently underwent a coronary artery bypass graft. This case highlights the presence of multiple coronary artery aneurysms and the ability to appreciate these pathologic findings on multiple imaging modalities, including coronary angiogram, transesophageal echocardiography, and direct visualization through the surgical field.

Bicuspid Aortic Valve and Aortic Root Morphology in Hispanic Patients.

BACKGROUND: The study aim was to evaluate the aortic valve and aortic root morphology in Hispanic patients with a bicuspid aortic valve (BAV). BAV disease is one of the most common congenital anomaly of the heart, and is associated with abnormalities of the aorta. Interracial differences have been described between Caucasian and African-American patients with BAV, which may have clinical and therapeutic implications. The clinical and anatomical spectrum of BAV disease in Hispanic patients has not been well established. METHODS: A retrospective review was conducted of all heart operations performed at the authors' institution between April 2008 and June 2013. Patients with BAV who underwent aortic valve replacement (AVR) were identified. All echocardiograms available were reviewed in order to compare cusp morphology, valvular function, and ascending aorta dimensions between Hispanic and non-Hispanic individuals. RESULTS: A total of 291 patients (159 Hispanic, 132 non-Hispanic) with a mean age of 62 ± 13 years were identified. The baseline characteristics were similar between the two groups. In both Hispanics and non-Hispanics, the most prevalent cusp morphology was fusion of the right and left coronary cusps (82% for both groups). The most common indication for surgery was aortic stenosis. Hispanic patients had a larger aortic annulus diameter (2.58 ± 0.32 cm versus 2.39 ± 0.39 cm, p = 0.04). However, this difference was not significant after adjusting for age, gender, body surface area, and the presence of moderate-to-severe aortic insufficiency. Ascending aortopathy was present in 42.7% of the total study population. Regardless of ethnicity, the most common pattern of aortopathy involved the tubular ascending aorta with mild to moderate root enlargement (type 1). CONCLUSIONS: Compared with other ethnic groups, Hispanics with BAVs have similar aortic valve morphology and function, as well as comparable aortopathy.

Incidence of cerebrovascular accidents in patients undergoing minimally invasive valve surgery.

OBJECTIVES: Minimally invasive valve surgery has been associated with increased cerebrovascular complications. Our objective was to evaluate the incidence of cerebrovascular accidents in patients undergoing minimally invasive valve surgery. METHODS: We retrospectively reviewed all the minimally invasive valve surgery performed at our institution from January 2009 to June 2012. The operative times, lengths of stay, postoperative complications, and mortality were analyzed. RESULTS: A total of 1501 consecutive patients were identified. The mean age was 73 ± 13 years, and 808 patients (54%) were male. Of the 1501 patients, 206 (13.7%) had a history of a cerebrovascular accident, and 225 (15%) had undergone previous heart surgery. The procedures performed were 617 isolated aortic valve replacements (41.1%), 658 isolated mitral valve operations (43.8%), 6 tricuspid valve repairs (0.4%), 216 double valve surgery (14.4%), and 4 triple valve surgery (0.3%). Femoral cannulation was used in 1359 patients (90.5%) and central cannulation in 142 (9.5%). In 1392 patients (92.7%), the aorta was clamped, and in 109 (7.3%), the surgery was performed with the heart fibrillating. The median aortic crossclamp and cardiopulmonary bypass times were 86 minutes (interquartile range [IQR], 70-107) minutes and 116 minutes (IQR, 96-143), respectively. The median intensive care unit length of stay was 47 hours (IQR, 29-74), and the median postoperative hospital length of stay was 7 days (IQR, 5-10). A total of 23 cerebrovascular accidents (1.53%) and 38 deaths (2.53%) had occurred at 30 days postoperatively. CONCLUSIONS: Minimally invasive valve surgery was associated with an acceptable stroke rate, regardless of the cannulation technique.

Pediatric death: guidelines for the grieving anesthesiologist.

This essay examines the effects of unexpected pediatric death on anesthesiology house staff, and offers a discussion of normal and abnormal patterns of grieving. The increased incidence of substance abuse and suicide among anesthesiologists is discussed, and the relationship of stress following patient death and appropriate coping skills is explored. A blueprint for managing stress is given based on a military combat stress model, and recommendations for residency training programs are made.
