The incidence of cardiovascular disease is rising as the population ages. This has led to an increase in the need to perform cardiac surgery in older patients. However, aged hearts are particularly susceptible to reperfusion injury following periods of myocardial ischemia that occur during cardiac surgery. Indeed, older adults experience myocardial dysfunction and reduced survival post-surgery compared to younger people and certain groups, including older women and frail older adults, are at particular risk...

BACKGROUND: Del Nido (DN) cardioplegic solution (CPS) has been widely used during pediatric cardiac surgery. However, its use in the field of adult cardiac surgery is not popular yet. We evaluated efficacy of DN cardioplegia in adult cardiac surgical patients. METHODS: Fifty-three adult patients (mean age, 54±16 years) who underwent cardiovascular surgery using DN cardioplegia were enrolled. Myocardial troponin I (TnI) level up to three days after surgery and early clinical outcomes were evaluated...

OBJECTIVE: Aortic occlusion with an endoballoon is a well-established technique to facilitate robotic and minimally invasive mitral valve surgery. Use of the endoballoon has several relative contraindications including ascending aortic dilatation greater than 38 mm in size. We sought to review our experience using the endoballoon in cases of totally endoscopic mitral valve surgery with aortic diameters greater than 38 mm. METHODS: A retrospective review of our single-site database was conducted to identify patients undergoing totally endoscopic mitral valve surgery by a single surgeon using an endoballoon and who had ascending aortic dilation...

The presence of cold agglutinins (CA) during cardiac surgery with cardiopulmonary bypass usually creates the need for an altered surgical plan. In this case, the CA were discovered after the initiation of bypass, limiting the time, and cardioplegia solutions that could be used in the new approach. The inability to cannulate the coronary sinus with a retrograde cardioplegia catheter excluded the standard approach to myocardial preservation with CA of using continuous warm blood. For this case, we used intermittent cold crystalloid delivered via the antegrade needle for the first half of the procedure and through the saphenous vein graft anastomosis during the aortic valve portion of the cross-clamp period...

There are many cardioplegia solutions currently in use for pediatric cardiopulmonary bypass (CPB). The most common being del Nido solution. Another common cardioplegia solution used for pediatric CPB is St. Thomas. In October 2014, Children's Mercy Kansas City changed from the use of modified St. Thomas to del Nido. This study compared rates of post cross-clamp fibrillation requiring defibrillation between del Nido solution and modified St. Thomas solution stratified by weight at Children's Mercy Kansas City...

Open aortic arch surgery after coronary artery bypass grafting (CABG) is considered a high-risk operation. We reviewed our surgical approach and outcomes to establish the risk profile for this patient population. In methods, from 2000-2014, 650 patients underwent aortic arch surgery with circulatory arrest. Of these, 45 (7%) had previous CABG. Complete medical record was available for review including all preoperative coronary angiograms and detailed management of myocardial protection. In results, the mean interval from previous CABG to aortic arch surgery was 6...

Incessant scar related re-entrant ventricular tachycardia is an important cause of morbidity and mortality. In patients not amenable to emergent radiofrequency catheter ablation, selective transcoronary alcohol ablation has been successfully performed. In our case study, we introduce the novel use of cardioplegia as a mapping technique for identification of the critical ventricular tachycardia isthmus to guide efficient transcoronary alcohol ablation and prevent unnecessary myocardial damage.

BACKGROUND: Hearts donated after circulatory death may represent an additional donor source. The influx of sodium and calcium ions across the sarcolemma play a central role in the pathogenesis of ischemia-reperfusion injury; however, this process may be inhibited if the initial reperfusion solution is rendered hypocalcemic and acidic. We sought to determine the calcium concentration and pH of the initial reperfusion solution that yielded optimal functional recovery of hearts donated after circulatory death during ex vivo heart perfusion...

OBJECTIVES: To investigate whether adding carvedilol, a nonselective β- and selective α1-receptor blocking agent with antioxidant properties, to oxygenated blood cardioplegia improves myocardial function after weaning from bypass. DESIGN: A randomized controlled study. SETTING: A university laboratory. PARTICIPANTS: Twenty anesthetized pigs, Norwegian Landrace. INTERVENTIONS: On cardiopulmonary bypass, cardiac arrest was induced with cold (12°C), oxygenated blood cardioplegia, enriched with carvedilol or vehicle, and repeated every 20 minutes...

Obesity is a risk factor of cardiovascular diseases. However, in the case of heart failure, obese and overweight patients have a more favourable prognosis compared to patients who have a normal body weight. This phenomenon is referred to as the "obesity paradox," and it is explained by, among others, a positive effect of adipokines produced by adipose tissue, particularly by the tissue located in the direct vicinity of the heart and blood vessels. The favourable effect on the cardiovascular system is mostly associated with adiponectin and omentin, but the levels of these substances are reduced in obese patients...

The purpose of this study is to report our experience with del Nido cardioplegia (DNC) in the setting of minimally invasive aortic valve surgery. Forty-six consecutive patients underwent minimally invasive aortic valve replacement (AVR) through a "J" ministernotomy: twenty-five patients received the DNC (Group 1) and 21 patients received standard blood cardioplegia (SBC) (Group 2). The rate of ventricular fibrillation at unclamping was significantly lower in the DNC group (12% vs 52%, p=0.004), as well as postoperative creatinine kinase-MB (CK-MB) values (11...

OBJECTIVES: Single-dose del Nido cardioplegia has been used in the pediatric population for many years. Only a small amount of data exists about its use in adult cardiac surgery. We sought to compare the outcomes of all patients undergoing coronary artery bypass, using our 4:1 blood cardioplegia versus single-dose 1:4 del Nido cardioplegia, at our institution. METHODS: Data were retrospectively reviewed from all patients during 2 consecutive years (2013-2014). We switched our cardioplegia protocol from 4:1 blood cardioplegia to exclusively 1:4 single-dose del Nido cardioplegia in early 2014...
