Valve Replacement for Massive Hemoptysis in Mitral Stenosis: An Uncommon Course in Modern Practice.

Massive hemoptysis is uncommon in mitral stenosis in contemporary practice. We report a patient without any previous illness presenting with life-threatening pulmonary hemorrhage, who was initially managed as cryptogenic hemoptysis. Once mitral stenosis was confirmed, the patient underwent mitral valve replacement with total and complete cessation of bleeding.

Intraoperative 2D and 3D transesophageal echocardiographic assessment of cor triatriatum with ostium secundum atrial septal defect in an adult patient.

Cor triatriatum is a rare congenital cardiac anomaly. Majority of the cases present in the childhood with an incidence of 0.4%. However, we report a case of cor triatrium sinister with ostium secundum atrial septal defect (ASD) in a 39-year-old female. The intraoperative 3D transesophageal echocardiography (TEE) offers an advantage over 2D TEE in visualizing the interatrial septum and the attachments of the fibromuscular accessory membrane in the left atrium (LA), which could help in surgical decision-making in this patient.

Perioperative management of transcatheter, aortic and mitral, double valve-in-valve implantation during pregnancy through left ventricular apical approach.

Pregnant women with stenotic degeneration of bioprosthetic cardiac valves may require another valve replacement procedure when their symptoms deteriorate with progression of pregnancy, but fetal mortality is higher with cardiac surgery done on cardiopulmonary bypass. Transcatheter valve-in-valve implantation may help to improve the fetal and maternal outcomes in these situations. Double valve-in-valve implantation is rare and has not been reported in a pregnant patient. We report, for the first time, the case of a pregnant woman with stenotic bioprosthetic valves in the mitral and aortic positions, who underwent a successful concomitant, transcatheter, double valve-in-valve implantation through the left ventricular apical route during the second trimester of her precious pregnancy.

Left ventricular global systolic function assessment by echocardiography.

The left ventricle, with its thickened myocardial walls, unlike the right ventricle has no measurable geometric shape. It has a conical apex and its function quantification, needs intensive, 2D, 3D and M mode transesophageal echocardiography, which is described in this review.

Management of infants with large, unrepaired ventricular septal defects and respiratory infection requiring mechanical ventilation.

OBJECTIVES: We sought to describe the hospital management and early outcome of critically ill infants presenting with large ventricular septal defects and pneumonia requiring mechanical ventilation at a referral center in a developing country. Infants with large ventricular septal defects who have pneumonia might present with respiratory failure requiring mechanical ventilation. In the developing world this presentation is relatively common, but few data exist describing patient management strategies. METHODS: Hospital data of consecutive infants admitted with large ventricular septal defects and pneumonia requiring mechanical ventilation were reviewed and analyzed. RESULTS: We identified 18 infants (mean age, 3.6 +/- 3.0 months). On admission, all the infants were significantly malnourished, and echocardiography showed bidirectional shunting (predominantly right-to-left shunting) in 6 infants. Thirteen (72%) patients improved with intensive medical management that included mechanical ventilation for 1 to 16 days (median, 6.5 days); unequivocal left-to-right shunting was subsequently documented by means of echocardiography in all 13 patients. Twelve patients underwent surgical repair, and 11 (91.6%) were discharged after median mechanical ventilation of 100 hours (range, 42-240 hours) and intensive care unit stay of 8 days (range, 4-15 days). Five of 6 unoperated patients died, 4 of them within a few hours of admission. One child with multiple ventricular septal defects was discharged and subsequently underwent pulmonary artery banding. CONCLUSION: Corrective cardiac surgery for selected critically ill infants with large ventricular septal defects, severe malnutrition, and pneumonia requiring mechanical ventilation is feasible and should be considered a viable management strategy.

Coronary artery bypass grafting in a patient with protein S deficiency: perioperative implications.

Protein S (PS) along with activated protein C plays an important role in the down-regulation of in vivo thrombin generation. Its deficiency can cause abnormal and inappropriate clot formation within the circulation necessitating chronic anticoagulation therapy. The risk of developing thrombotic complications is heightened in the perioperative period in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB). Heparin resistance is very rare in these patients, especially when antithrombin levels are near normal. Management of CPB in this scenario is quite challenging. We report the perioperative management, particularly the CPB management, of a patient with type I PS deficiency and incidentally detected heparin resistance, who underwent coronary artery bypass grafting with CPB.

Off-pump coronary artery bypass grafting through left antero-lateral thoracotomy (thora-cab) - case report and review of literature.

We report the first case of off-pump complete myocardial revascularization through antero-lateral thoracotomy (Thora-CAB) in Middle-East. 69 year old gentleman having angina pectoris for last three years with severe double vessel disease involving the left anterior descending artery (95% proximal lesion) and the circumflex system (80% mid circumflex lesion with significant osteal disease in obtuse marginal) and insignificant disease in right coronary artery with moderate left ventricular impairment underwent Thora-CAB. Post-operatively, he had minimal pain, quick symptomatic improvement and no complications. He was discharged home on 5th post-operative day. This indicates that the thoracotomy approach is safe and practical for CABG. It is well tolerated hemodynamically with no/ minimal post-operative morbidity.

Determinants of early outcome after neonatal cardiac surgery in a developing country.

OBJECTIVE: Significant technologic advances have improved outcomes in neonatal cardiac surgery over the past 3 decades. However, outcomes might be different in developing countries with resource limitations. We sought to identify the determinants of early outcome after neonatal cardiac surgery in a tertiary referral center in South India. METHODS: Hospital records of 330 consecutive neonates who underwent surgical intervention between January 1999 and April 2006 were reviewed, and perioperative variables were recorded. Main outcome measures were 30-day mortality, postoperative bloodstream infection, and hospital stay of longer than 10 days. Multivariate logistic regression analysis was performed. RESULTS: Overall mortality was 8.8%. Mortality significantly decreased from 21.4% before 2002 to 4.3% after 2002 (3.2% for corrective operations, P < .0001). The prevalence of postoperative bloodstream infection remained the same, whereas surgical site infection and hospital stay significantly increased after 2002. Predictors of outcomes on multivariate analysis were as follows: (1) mortality--operation before 2002 (odds ratio, 5.5), age less than 7 days (odds ratio, 3.8), preoperative antibiotic use (odds ratio, 5.6), and postoperative exchange transfusion (odds ratio, 14.9); (2) postoperative bloodstream infection (21.2%)--use of cardiopulmonary bypass (odds ratio, 2.0), reintubation (odds ratio, 7.7), and surgical site infection (odds ratio, 4.1); and (3) hospital stay of longer than 10 days (61.2%)--use of cardiopulmonary bypass (odds ratio, 2.8), delayed sternal closure (odds ratio, 3.6), reintubation (odds ratio, 12.1), surgical site infection (odds ratio, 13.8), and postoperative antibiotic use (odds ratio, 4.4). CONCLUSIONS: With increasing experience, neonatal cardiac surgery can be performed with excellent outcomes in developing countries with resource limitations. Infectious complications contribute significantly to morbidity and mortality, and improvements in infection-control practices should be emphasized to improve outcomes further.
