Our 10-Year Experience with Atrial Myxomas: Is Concurrent Valve Intervention Really Warranted?

INTRODUCTION: Primary cardiac myxomas are rare tumors. Concurrent valvular lesion is a common finding on evaluation which is thought to be due to annular dilatation secondary to tumor movement across the valve, functional obstruction across the valve, and severe pulmonary hypertension secondary to chronic obstruction. A common belief among surgeons is that excision of myxoma leads to abatement of symptoms, and further valve intervention may not be warranted. METHODS: A 10-year retrospective descriptive study was designed to analyze patients who underwent excision of cardiac myxoma at our center. Data was analyzed regarding presenting features, echocardiographic findings of myxoma and valve morphology, intraoperative assessment, and postoperative outcome with/without valve repair/replacement in all patients. RESULTS: A total of 22 patients underwent surgery for myxoma. Six patients underwent successful mitral valve repair with ring annuloplasty, two had moderate mitral regurgitation, three had severe mitral regurgitation, and one patient had no mitral regurgitation on preoperative assessment, but moderate mitral regurgitation was found intraoperatively. Four of these patients had no residual mitral regurgitation in follow-up period while two had mild residual mitral regurgitation. One patient had severe mitral stenosis of concurrent rheumatic etiology and successfully underwent mitral valve replacement. CONCLUSION: Cardiac myxomas are rare benign tumors commonly associated with mitral valve insufficiency. Mitral valve should be assessed intraoperatively after excision of mass as preoperative assessment might often be insufficient. Concomitant mitral valve intervention might be needed with a case-specific tailored approach, and mitral valve repair with ring annuloplasty offers best surgical outcome in such cases.

Anomalous origin of the left coronary artery from the pulmonary artery: A midterm experience of a rare entity at a tertiary care center.

ALCAPA is a rare congenital heart disease. Presentation varies from asymptomatic to progressive heart failure and death. Surgical repair is indicated in all patients with a goal of restoring two coronary systems. Data was analysed in regard to presenting features, echocardiographic findings, various surgical approaches used and immediate, early and midterm post-operative results. Most common presentation was growth failure and seen in 6 patients. One patient was taken for elective PDA ligation and diagnosis of ALCAPA was made on table after PDA ligation as patient crashed subsequently. Aortocoronary button transfer was most commonly used surgical technique while 2 patients needed interposition grafting. LV function improved in 5 out of 8 patients with regression of MR. A median improvement of 5+-2% was observed in ejection fraction of 5 patients. Early surgery with aortocoronary transfer offers good results with gradual improvement in LV dysfunction and mitral regurgitation.

Study of outcomes of perforated appendicitis in adults: a prospective cohort study.

Acute appendicitis remains the most common general surgical emergency seen in most hospitals and the most common cause of acute abdomen requiring surgical intervention. Aim: The aim was to study the intraoperative features and postoperative outcomes of appendicular perforation in adults. Objectives: First, to study the incidence, clinical presentation, and complications of perforated appendicitis in a tertiary care hospital. Second, to study morbidity and mortality in an operated case of perforated appendicitis. Materials and Methods: This prospective observational study was conducted at a tertiary care centre in a government setup from August 2017 to July 2019. Data were collected from patients (N=126) who had an intraoperative finding of perforated appendicitis. The inclusion criteria are as follows: patients over the age of 12 with a perforated appendix, as well as any patients with intraoperative findings like perforated appendicitis, gangrenous perforated appendicitis, or a disintegrated appendix. The exclusion criteria are as follows: all patients with appendicitis below 12 years of age with perforated appendicitis; all patients with appendicitis with intraoperative findings of acute nonperforated appendicitis; and all patients with intraoperative findings of an appendicular lump or mass. Results: Perforation was found in 13.8% of the cases of acute appendicitis in this study. With a mean age of 32.5 years, the most common age of presentation in perforated appendicitis was 21-30 years. The most prevalent presenting symptom in all patients (100%) was abdominal pain, followed by vomiting (64.3%) and fever (38.9%). Patients with perforated appendicitis had a 72.2% complication rate. Peritoneal pollution of more than 150 ml was linked to a 100% increase in morbidity and mortality (54.5%). The mean duration of the hospital stay in patients with a perforated appendix was 7.28±5 days. Surgical site infection (42%) was the most common early complication, followed by wound dehiscence (16.6%), intestinal obstruction (1.6%), and faecal fistula (1.6%). The most common late complications were intestinal obstruction (2.4%), intra-abdominal abscess (1.6%), and incisional hernia (1.6%). The mortality rate in patients with perforated appendicitis was 4.8%. Conclusion: To conclude, prehospital delay was an important factor contributing to appendicular perforation and leading to adverse outcomes. A higher rate of morbidity and prolonged duration of hospital stay were seen in patients with delayed presentation, with features of generalised peritonitis and perforation of the base of the appendix. Delayed presentations in as elderly population with underlying co-morbid conditions associated with severe peritoneal contamination were associated with higher mortality (26%) in perforated appendicitis. Conventional surgery and open procedures remain the preferred approach in a government setup like ours where laparoscopy may not be available during odd hours. Since this study was done over a short duration, certain long-term outcomes could not be assessed. Hence, there is still a need for further studies.
