Comparison of Antihypertensives after Coronary Artery Surgery

Hypertension following coronary artery bypass grafting is a common problem that may result in postoperative myocardial infraction or bleeding, Hemodynamic effects were compared in 45 hypertensive coronary bypass patients randomized to receive either diltiazem, nitroglycerin, or sodium nitroprusside. Diltiazem was administered as an intravenous bolus of 0.3 mg·kg−1 within 5 min, followed by infusion of 0.1–0.8 mg·kg−1·h−1 in group 1. Nitroglycerin was infused at a rate of 1–3 μg·kg·h−1 in group 2, and sodium nitroprusside was given at a rate of 1–3 μg·kg−1·min−1 in group 3. Hemodynamic measurements were carried out before infusion (T1) and at 30 min (T2), 2 h (T3), and 12 h (T4) after initiation of treatment in the intensive care unit. Mean arterial pressure decreased significantly in all groups. There were no differences among groups at T1 and T2. At T3, heart rate in group 2 was significantly higher than group 1. At T3 and T4, the double product was highest in group 3 (group 1 vs. 3, p < 0.001). These results suggest that the hemodynamic effects of the 3 drugs are similar within the first 30 min. However, after 30 min, diltiazem affords better myocardial performance and more effective control of hypertension.

A Modified Combined Approach to Operative Carotid and Coronary Artery Disease: 82 Cases in 8 Years

BACKGROUND A significant number of patients undergoing coronary artery surgery have severe carotid artery disease. It is also true that up to half of the patients undergoing carotid endarterectomy (CEA) have severe treatable coronary lesions. This study aims to review data regarding 82 patients of combined approach in 8 years; the second half consists of 44 patients whose CEA was performed under local anesthesia. It compares results of the conventional and the modified approaches to simultaneous surgery. METHODS All 82 patients who planned to have a concomitant procedure were recorded prospectively between 1995 and 2003. From 1998, the surgical technique has been modified to switch to local anesthesia for CEA, rather than perform under a single general anesthetic period. All pre-and perioperative data as well as in-hospital and outpatient control (mid- to long-term) data were recorded. A P-value of less than .05 was considered as significant. Analysis of survival was performed by using the Kaplan-Meier method and the log-rank test. RESULTS The 30-day follow-up was 100% complete for all patients. All patients were followed for 59.59 to 114 months) months postoperatively. Three patients (6.8%) in the modified and 2 (5.2%) in the standard group had intraluminal shunting (P > .05). In the standard group, 3 patients expired and 3 had perioperative stroke; only 1 patient had a stroke in the modified group and two expired (P > .05). Mean survival time according to Kaplan-Meier test was 109.97, SE 2.84, 95% CI (104.41-115.52) months for the former group, whereas it was 62.79, SE 1.20, 95% CI (60.4565.13) months for the latter. Actuarial estimates of survival during ten-year follow up were 94.44% SE 3.83 in ten-year follow-ups and 97.67% SE 2.30 in 5-year follow-ups for the modified group (P > .05). CONCLUSIONS Avoidance from extended periods of general anesthesia and cardiopulmonary bypass periods as well as immediate recognition of impaired cerebral flow during CEA and the time it provides to take preventive measures are the most important benefits of the modified technique without significantly changing hospital and long-term mortality and stroke. It may also reduce the cost and the waiting period for the suffering patient.

Spontaneous brachial pseudo-aneurysm in a 12-year-old with kyphoscoliosis-type Ehlers-Danlos Syndrome.

The Ehlers-Danlos Syndrome (EDS) is a rare connective tissue disorder characterised by fragility of the soft connective tissues and widespread manifestations in skin, ligaments, joints, blood vessels and internal organs. We report a case of a 12-year-old boy, previously diagnosed with kyphoscoliosis-type EDS (type VI), presenting with a left brachial artery pseudo-aneursym with history of multiple spontaneous and post-traumatic arterial ruptures. Surgical management of this patient was performed successfully by primary repair of brachial artery lesion.

Midterm Results With Endovascular Approach to Abdominal Aortic Pathologies in Behçet’s Disease

BACKGROUND Vascular involvement in Behcets disease is rare, but may be at the forefront of the clinical picture with possible life-threatening scenarios. We reviewed our preliminary results with endovascular treatment of abdominal aortic pathologies in Behçets disease. METHODS Data regarding seven patients with abdominal aortic pathologies (aneurysm, pseudoaneurysm, and aortoenteric fistula) and Behçets disease were treated with endovascular stent-grafting between 2002 and 2006. RESULTS Seven patients (aged, 39.1 ± 9; range, 27-52 years) with a mean aortic diameter of 58.4 ± 6.3 mm received endovascular stent-grafts, two patients being in emergency settings. Two patients were in active disease state. Four tube-shaped, two aorto-bi-iliac, and one aorto-uni-iliac stents were implanted. One patient expired on day 28 with multiorgan failure after emergency stent-grafting owing to enlarging periprosthetic hematoma following open surgery for ruptured aneurysm. Another patient was declined for endovascular therapy owing to hypoplastic aortoiliac vasculature. CONCLUSION Endovascular approach provides a reasonable alternative to open repair for the treatment of abdominal aortic aneurysms in select cases; however, in emergency settings, endovascular repair may well have an important, but limited, role in select patients with aortoenteric fistulae, it may yet require a surgical intervention.

Fast-track recovery in noncoronary cardiac surgery patients.

OBJECTIVE Fast-track recovery protocols result in shorter hospital stays and decreased costs in coronary artery bypass grafting (CABG) surgery. However, data based on an objective scoring system are lacking for the impact of these protocols on patients undergoing cardiac surgery other than isolated CABG. METHODS Between March 1999 and March 2003, 299 consecutive patients who underwent open cardiac surgery other than isolated CABG were analyzed to evaluate the safety and efficacy of fast-track recovery. The parameters evaluated as predictors of mortality, ie, delayed extubation (>360 minutes), intensive care unit (ICU) discharge (>24 hours), increased length of hospital stay (>5 days), and red blood cell transfusion, were determined by regression analysis. Standard perioperative data were collected prospectively for every patient. RESULTS Seventy-two percent of the patients were extubated within 6 hours, 87% were discharged from the ICU within 24 hours, and 60% were discharged from the hospital within 5 days. No red blood cells were transfused in 67% of the patients. There were no predictors of mortality. The predictors of delayed extubation were preoperative congestive heart failure (P = .005; odds ratio [OR], 4.5; 95% confidence interval [CI], 1.6-12.6) and peripheral vascular disease (P = .02; OR, 6; 95% CI, 1.9-19.4). Factors leading to increased ICU stay were diabetes (P = .05; OR, 3.6; 95% CI, 1-12.6), emergent operation (P = .04; OR, 6.1; 95% CI, 1.1-33.2), red blood cell transfusion (P = .03; OR, 2.9; 95% CI, 1.1-7.8), chest tube drainage >1000 mL (P = .03; OR, 3.4; 95% CI, 1.1-10.2). The predictors of increased length of hospital stay were ICU stay >24 hours (P = .001; OR, 5.9; 95% CI, 2-17), EuroSCORE >5 (P = .05; OR, 1.8; 95% CI, 1-3.2), and chronic obstructive pulmonary disease (P = .003; OR, 3.7; 95% CI, 1.5-8.7). Predictive factors for transfusion of red blood cells were diabetes (P = .04; OR, 2.9; 95% CI, 1.1-8.1), delayed extubation (P = .02; OR, 2.7; 95% CI, 1.4-5.1), increased ICU stay (P = .04; OR, 2.6; 95% CI, 1-6.4), and chest tube drainage >1000 mL (P = .001; OR, 4.3; 95% CI, 2-9.3). CONCLUSIONS This study confirms the safety and efficacy of the fast-track recovery protocol in patients undergoing open cardiac surgery other than isolated CABG.

Candida albicans endocarditis and a review of fungal endocarditis: case report.

Endocarditis due to fungal etiology is rare, but it is the most severe form of infective endocarditis. Fungal endocarditis is commonly complicated by systemic embolizations, and the difficulty in isolating the fungi with routine blood cultures complicates the diagnostic process. In these culture-negative cases of endocarditis, etiologic diagnosis is made with histopathologic examination of the cardiac valve, embolic materials, and systemic ulcers. In this case report, the presented patient with fungal endocarditis and its neurologic complications was treated with a surgical and medical approach.

Coronary artery bypass grafting in a 12-year-old girl with familial hypercholesterolemia.

Abstract We present the case of a 12-year-old girl with familial hypercholesterolemia and coronary artery disease. She underwent triple-vessel coronary artery bypass grafting with bilateral pedicled internal mammary artery grafting without adverse events. Pediatric patients with familial hypercholesterolemia may present with premature coronary atherosclerosis requiring coronary artery bypass grafting. In situ internal mammary artery grafts should be the graft of choice.

Mitral Valve Replacement with Bileaflet Preservation for Complex Annular Calcification

Extensive calcification of mitral apparatus may preclude optimal valve repair, thus requiring debridement. We performed mitral valve replacement in a 55-year-old woman with a modified bileaflet preservation technique to avoid complications related to extensive debridement. Posterior transposition of the anterior leaflet as a buttress over the posterior ventricular wall provided extra support for the weakened tissues and covered the decalcified areas, which protected against debris embolism. This technique is safe and reproducible, especially for elderly patients who have complex calcification that requires extensive debridement, enables better preservation of ventricular function, and avoids disruption of the mechanical left ventricular wall.

Stenting for Stenosing Takayasu Aortitis Following Carotid Artery Stenosis in a 32-Year-Old Patient

Takayasu arteritis is a chronic granulomatous vasculitis with multivessel involvement, causing significant mortality and morbidity in affected individuals. A 32-year-old patient with severe right common carotid stenosis underwent expanded polytetrafluoroethylene graft interposition to the carotid artery. A bare Wallstent endoprosthesis (Boston Scientific Medi-Tech, Natick, MA) was implanted for the abdominal aortic stenosis incidentally diagnosed during follow-up 1 year after the carotid operation while the disease was inactive. Close follow-up of the activity of the vasculitic process is warranted owing to the progression of the vascular lesions or formation of de novo lesions in Takayasu disease.

Isolated partial anomalous pulmonary venous connection of the left lung.

Isolated partial anomalous pulmonary venous connection (PAPVC) of the entire left lung is a rare congenital anomaly with incidental diagnosis and vague symptoms, if any, until late adulthood. If left untreated, PAPVC may result in severe right ventricular failure and pulmonary vascular disease. We present the case of a 34-year-old woman with isolated PAPVC of the entire left lung. The patient underwent operation with a side-to-side left atrio-vertical vein anastomosis while on cardiopulmonary bypass and under cardioplegic arrest. She was discharged without complications and with a gradient of 2 mm Hg across the anastomosis. Left-sided PAPVC can be repaired with minimal morbidity and mortality. Surgical correction is warranted when patients are symptomatic or show evidence of right-sided overload due to unpredictability of the natural course. Recent data demonstrate that both on-pump and off-pump surgical procedures produce excellent long-term outcomes when performed without persisting gradients.
