Respiratory Distress and Chest Pain in an Airplane Passenger With Radiolucent Left Hemithorax.

CASE PRESENTATION: A 43-year-old man experienced sudden onset of chest pain and shortness of breath onboard a domestic flight. After consultation with the airline's operations center, a decision was made to land the plane in its destination airport. After landing, an ambulance was ready, and the patient was transferred to the ED in our facility. Patient evaluation was immediately started, and oxygen supply and venous access were secured.

Repair of quadricuspid aortic valve associated with ascending aorta dilatation.

Quadricuspid aortic valve is a rare congenital anomaly that may require surgical intervention because of valvular dysfunction. Rarely, it may be associated with enlargement of the ascending aorta. Here, the case is presented of a quadricuspid aortic valve-associated enlargement of the ascending aorta and functional aortic annulus dilatation in a 36-year-old patient. The patient subsequently underwent a successful aortic valve repair and replacement of the ascending aorta.

Is bilateral internal thoracic artery use safe in the elderly?

BACKGROUND: The strategy of bilateral mammary artery grafting is often not considered for elderly patients due to perceived concerns of increased morbidity and mortality. The objective of this study is to explore the safety of bilateral mammary in elderly patients. METHODS: Out of 7746 patients who underwent coronary artery bypass grafting using at least one internal thoracic artery (ITA), there were 3940 patients aged 65 years or greater, and of those, 3581 patients had a single ITA (SITA) and 359 patients had bilateral ITAs (BITAs). The primary outcome was the incidence of major adverse cardiac or cerebrovascular events (MACCEs). Secondary outcomes included re-exploration for bleeding, blood transfusions, sternal wound infections, and intensive care unit and hospital length of stay. RESULTS: The incidence of mortality and MACCE were similar in both groups (mortality BITA 2.6%, SITA 3.6%, p = 0.25, MACCE BITA 8.5%, SITA 6.1%, p = 0.13). Superficial and deep sternal site infections were significantly more prevalent in the BITA group than the SITA group [superficial OR 0.42, 95% CI [0.23-0.75] (p = 0.003) and deep OR 0.29, 95% CI [0.14-0.58 (p = 0.0005)]. CONCLUSION: Use of BITA is safe in the elderly with respect to mortality and early cardiovascular outcome. BITA use in the elderly is associated with an increased risk of sternal wound infection. Our experience in this situation suggests that there is a maximum age (approximately 74 years) beyond which the combined risk of MACCE and wound complications supersedes the benefits in terms of sternal infections.

Recurrent cardiac constriction after complete pericardiectomy.

We present a patient with recurrent constrictive physiology resulting from exuberant post-operative fibrosis after complete pericardiectomy. The patient underwent a repeat stripping procedure. At surgery, there was an extensive fibrotic and calcified rind around the heart. The recurrence of constriction physiology after complete pericardiectomy in non-tuberculous pericarditis is a rarely reported in literature. The management supports repeat surgery and the potential value of steroid administration.

Headscarf pin, a sharp foreign body aspiration with particular clinical characteristics.

The process of wearing head scarf is very complex; girls used to hold a number of pins in the mouth and utilize them one by one to fix the scarf. Loss of concentration results in pin aspiration. We presented our experience with scarf pin aspiration and discussed the unique clinical characteristics of this problem. We reviewed the records of 73 patients who underwent bronchoscopy for scarf pin inhalation during the period from January 1995 to May 2009. The following data were collected, history of aspiration, time lag before presentation, symptoms and signs, radiological findings, bronchoscopic findings, number of repeated bronchoscopy, complications, need for thoracotomy and time of discharge. All patients were female, mean age 13.4 years. The time lag before admission was <12 h for 59 (81%) patients. Positive history was present in all cases. Chest radiography identified the pins in all cases. The foreign bodies were seen in the left bronchial system in 37 (50.7%) patients, in the right bronchial system in another 24 (32.9%), and in the trachea in 12 (16.4%) patients. In 66 (90.4%) patients, the foreign body was removed in the first bronchoscopic trial; a second trial was needed in 5 (6.8%) patients, and thoracotomy was performed in two patients. In conclusion, head scarf pin aspiration occurs in adolescent Islamic girls. The clinical presentation and radiological findings are diagnostic in all cases. Rigid bronchoscopy is the preferred treatment modality. Health education is the key issue in the prevention of this problem.

Intraoperative loading dose of amiodarone for prophylaxis against atrial fibrillation after valvular heart surgery.

OBJECTIVE: Benefit of amiodarone in restoring sinus rhythm (SR) after cardiac surgery was concluded in previous studies that used different protocols for giving amiodarone. The purpose of this study was to assess the use of single parenteral intraoperative loading dose of amiodarone without maintenance as prophylaxis against atrial fibrillation (AF) after valvular heart surgery. MATERIALS AND METHODS: This was a prospective, randomized, double-blind controlled study on 94 patients listed for valvular heart surgery. The patients received either amiodarone, 3 mg/kg diluted in 100 ml of normal saline and started prior to making skin incision and administrated through venous line over a period of 30 minutes, or the same volume of normal saline infused in a similar fashion. The incidence of AF during the first 5 days after surgery was the main outcome measured. RESULTS: There was significant difference in favor of the amiodarone group regarding restoration of sinus rhythm after aortic cross-clamp removal, number of patients requiring cardioversion, incidence of AF and the time elapsed before incidence of it postoperatively (P values=0.02, 0.04, 0.02, 0.02, respectively). There was no difference in hospital mortality, major postoperative morbidity, intensive care unit (ICU) stay or hospital stay. CONCLUSIONS: Amiodarone prophylaxis in a single intraoperative dose was significantly effective in prevention of new-onset postoperative AF after valvular heart surgery. This amiodarone dose is well tolerated and not associated with postoperative complications.

Is concomitant surgery for moderate functional mitral regurgitation indicated during aortic valve replacement for aortic stenosis? A systematic review and evidence-based recommendations.

BACKGROUND: Mitral regurgitation (MR) is associated with poor clinical outcomes. Functional MR is often associated with aortic stenosis (AS) and may resolve after aortic valve replacement (AVR). The objective of this study was to derive evidence-based recommendations regarding surgical intervention for moderate functional MR at the time of AVR for AS. METHODS: An exhaustive literature search strategy including Medline, Embase, the Cochrane library, and meeting abstracts was performed. Studies meeting inclusion criteria were critically appraised and data pooled according to accepted meta-analysis techniques. The primary outcome was change in moderate MR after isolated AVR. Secondary outcomes were the impact of functional MR on survival and identifying factors that predict progression of MR, in patients undergoing isolated AVR for AS. RESULTS: Thirteen nonrandomized studies including 2113 patients were reviewed. A total of 268 patients had preoperative moderate functional MR and AS. All studies were appraised as poor methodological quality. After isolated AVR a trend toward improvement in MR was observed. Left ventricular dysfunction, left atrial enlargement, and atrial fibrillation were associated with progression of MR after AVR. However, the impact of residual MR on late survival was not consistent. CONCLUSION: Pooling current evidence provided inconclusive evidence to make clinical practice recommendations for or against routine surgical intervention of moderate MR at the time of AVR for AS. The incidence of this pathology makes further clinical trial studies warranted.

Predictors of packed red cell transfusion after isolated primary coronary artery bypass grafting--the experience of a single cardiac center: a prospective observational study.

BACKGROUND: Preoperative patients' characteristics can predict the need for perioperative blood component transfusion in cardiac surgical operations. The aim of this prospective observational study is to identify perioperative patient characteristics predicting the need for allogeneic packed red blood cell (PRBC) transfusion in isolated primary coronary artery bypass grafting (CABG) operations. PATIENTS AND METHODS: 105 patients undergoing isolated, first-time CABG were reviewed for their preoperative variables and followed for intraoperative and postoperative data. Patients were 97 males and 8 females, with mean age 58.28 +/- 10.97 years. Regression logistic analysis was used for identifying the strongest perioperative predictors of PRBC transfusion. RESULTS: PRBC transfusion was used in 71 patients (67.6%); 35 patients (33.3%) needed > 2 units and 14 (13.3%) of these needed > 4 units. Univariate analysis identified female gender, age > 65 years, body weight < or = 70 Kg, BSA < or = 1.75 m(2), BMI < or = 25, preoperative hemoglobin < or = 13 gm/dL, preoperative hematocrit < or = 40%, serum creatinine > 100 micromol/L, Euro SCORE (standard/logistic) > 2, use of CPB, radial artery use, higher number of distal anastomoses, and postoperative chest tube drainage > 1000 mL as significant predictors. The strongest predictors using multivariate analysis were CPB use, hematocrit, body weight, and serum creatinine. CONCLUSION: The predictors of PRBC transfusion after primary isolated CABG are use of CPB, hematocrit < or = 40%, weight < or = 70 Kg, and serum creatinine > 100 micromol/L. This leads to better utilization of blood bank resources and cost-efficient targeted use of expensive blood conservation modalities.

Isolated rib fractures in geriatric patients.

INTRODUCTION: The goal of this study was to investigate the short-term outcomes in patients older than 60 years with isolated rib fractures and admitted to emergency hospital. MATERIALS AND METHODS: This study included patients who were 60 years old or more and sustained blunt chest injury and had isolated rib fractures. The following data were obtained from the medical records: age, gender, number of fracture ribs, side of fracture ribs, mechanism and nature of injury, preexisting medical conditions, complications, admission to intensive care unit (ICU), need for mechanical ventilation, length of ICU and hospital stay and mortality. RESULTS: For the study, 39 patients who were 60 years old or more and admitted to the hospital because of isolated rib fractures were enrolled. There were 28 males (71.7%) and 11 females (28.3%) with mean age of (66.84 +/- 4.7) years. No correlation was found between comorbidities and hospital outcomes except in those who were diabetic (P-value = 0.005) and those with chronic lung disease (P-value = 0.006). Pulmonary complications were the most frequent complications encountered in those patients. Pulmonary complications were: lung contusion in 8 patients (20.5%) and pulmonary infection in 6 patients (15.8%). CONCLUSION: Elderly patients sustaining blunt chest trauma had significant morbidity and potential for mortality.
