Department of Surgery Faculty Papers

Background: Robotic-assisted mitral valve surgery (RMVS) is becoming an increasingly performed procedure in cardiac surgery, however, its true safety and efficacy compared to the gold standard conventional sternotomy approach [conventional sternotomy mitral valve surgery (CSMVS)] remains debated. The aim of this meta-analysis was to provide a comprehensive analysis of all available literature comparing RMVS to CSMVS.

Methods: An electronic search of five databases was performed to identify all relevant studies comparing RMVS to CSMVS. Pre-defined primary outcomes of interest included all-cause mortality, cerebrovascular accidents (CVA) and re-operation for bleeding. Secondary outcomes of interest included cross clamp time, cardiopulmonary bypass (CPB) …

Faculty, Staff and Student Publications

BACKGROUND: Ambulatory blood pressure monitoring (ABPM) is routinely performed in children with chronic kidney disease to identify masked hypertension, a risk factor for accelerated chronic kidney disease progression. However, ABPM is burdensome, and developing an accurate prediction of masked hypertension may allow using ABPM selectively rather than routinely.

METHODS: To create a prediction model for masked hypertension using clinic blood pressure (BP) and other clinical characteristics, we analyzed 809 ABPM studies with nonhypertensive clinic BP among the participants of the Chronic Kidney Disease in Children study.

RESULTS: Masked hypertension was identified in 170 (21.0%) observations. We created prediction models for …

Coronary-To-Coronary Bypass Grafting In Aortoarteritis: A Case Report, Immaneni Sathyamurthy, Narra Lavanya, Kanthallu Narayanamoorthy Srinivasan, Maligail Ramkrishna Girinath

Faculty, Staff and Student Publications

Takayasu's arteritis (TA) is an idiopathic vasculitis affecting the aorta and its major branches. In TA, coronary artery involvement is rare and it mainly consists of stenosis or occlusion of the coronary ostia. In TA, as the arterial tree is diseased, often, arterial grafts are unsuitable for grafting so the saphenous vein grafts (SVG) are commonly used. We present a case of a young female with TA with an ostial left main stenosis who has undergone a right coronary-to-left anterior descending artery SVG and put on immunosuppression and steroids. She was asymptomatic with a patent graft during 7 years follow-up.

Complications Of Tavr From An Anesthesia Perspective, David R. Kingery Jr., Alex Roberts, Derek Horstemeyer, Russell Stahl

HCA Healthcare Journal of Medicine

Transcatheter aortic valve replacement (TAVR) has become the predominant technique for aortic valve replacement in the United States. Initially approved for high surgical risk patients, TAVR is now approved for most patients requiring valve therapy, including younger, lower-risk patients. The procedure is ideally performed in a hybrid operating room equipped with fluoroscopic equipment and transesophageal echocardiogram (TEE) imaging that can be viewed simultaneously by the operating team. The operating room should also be equipped to allow initiation of cardiopulmonary bypass, if necessary. Cardiac anesthesia teams are often involved with the management of these patients. This mini-review is designed to summarize …

The association of chronic cough, chronic phlegm, wheeze, dyspnoea, FEV1/FVC and FVC with occupation was assessed, per study site, using multivariable regression. These estimates were then meta-analysed. Sensitivity analyses explored differences between sexes and gross national income …


Double-Inlet Left Ventricle, P Syamasundar Rao Aug 2022

Double-Inlet Left Ventricle, P Syamasundar Rao

Faculty, Staff and Student Publications

Double-inlet left ventricle (DILV) is most frequent among univentricular atrioventricular connections. In DILV, there is a single functioning ventricle, most commonly with left ventricular structure. This chamber receives both atrioventricular valves and is connected to an outlet chamber with morphologic features of the right ventricle. The great vessels are often transposed, and pulmonary stenosis is seen in two-thirds of patients. The anatomy and pathophysiology can be defined by echo-Doppler studies with a rare need for other imaging studies. The management is mostly related to the nature of associated heart defects and the degree of pathophysiological abnormality. When the infants present …

Despite increasing availability and more successful interventional approaches to restore coronary reperfusion, myocardial ischemia-reperfusion injury is a substantial cause of morbidity and mortality worldwide. During myocardial ischemia, the myocardium becomes profoundly hypoxic, thus causing stabilization of hypoxia-inducible transcription factors (HIF). Stabilization of HIF leads to a transcriptional program that promotes adaptation to hypoxia and cellular survival. Transcriptional consequences of HIF stabilization include increases in extracellular production and signaling effects of adenosine. Extracellular adenosine functions as a signaling molecule via the activation of adenosine receptors. Several studies implicated adenosine signaling in cardioprotection, particularly through the activation of the Adora2a and Adora2b …

Journal of Shock and Hemodynamics

Patients with coronavirus disease of 2019 (COVID-19) may present with a wide range of symptoms ranging from asymptomatic to critically ill. Approximately 10-14% of patients require hospitalization. Those individuals requiring hospitalization can deteriorate rapidly with worsening hypoxemia or new-onset pneumonia, resulting in 20-30% of patients developing acute respiratory distress syndrome (ARDS).

When refractory to medical management, severe ARDS secondary to other illnesses has been successfully treated with extracorporeal membrane oxygenation (ECMO). We completed a comprehensive literature review of ECMO utilization for patients with severe COVID-19 who were unresponsive to critical care management. Of the 1419 patients with a reported diagnosis …
