Drug-Eluting Balloon for Management of Coronary In-Stent Restenosis in a South Asian Population: Experience From a Tertiary-Care Hospital in Pakistan.

Background: Emerging evidence suggests that the South Asian (SA) population has an increased rate of in-stent stenosis (ISR) after percutaneous coronary intervention (PCI) when compared with other ethnicities. Drug-eluting balloons (DEBs) have emerged as a viable option for the treatment of ISR. However, data describing the outcomes of DEB-PCI in the SA population are limited.

Prognostic Significance of CMR Findings in Patients with Known Coronary Artery Disease - Experience from a South Asian Country.

Objectives: South Asians (SA) have a higher burden of coronary artery disease (CAD) and are known to have a worse prognosis compared to other ethnicities. Therefore, it is imperative to improve the risk stratification of SA patient with CAD and to seek out newer prognostic markers beyond the conventional echocardiography.The aim of this study was to investigate whether variables obtained by cardiac magnetic resonance (CMR) improve risk stratification of South Asian patients with known CAD.

Cardiac Magnetic Resonance Evaluation of Cardiac Masses in Patients with Suspicion of Cardiac Masses on Echo or Computed Tomography.

Objectives: In recent years, cardiac magnetic resonance (CMR) imaging has emerged as an important tool in the identification and characterization of cardiac masses. No imaging data on cardiac masses are available from Pakistan. We aimed to review the clinical presentation, CMR findings, and outcome of patients referred for CMR due to suspicion of cardiac masses on echocardiogram or computed tomography (CT).

On the Effects of Process Parameters and Optimization of Interlaminate Bond Strength in 3D Printed ABS/CF-PLA Composite.

The scope of additive manufacturing, particularly fused deposition modelling (FDM), can indeed be explored with the fabrication of multi-material composite laminates using this technology. Laminar composite structures made up of two distinct materials, namely acrylonitrile butadiene styrene (ABS) and carbon fiber reinforced polylactic acid (CF-PLA), were produced using the FDM process. The current study analyzes the effect of various printing parameters on the interfacial bond strength (IFBS) of the ABS/CF-PLA laminar composite by employing response surface methodology.

Thoracoscopic evacuation of retained post-traumatic hemothorax.

Post-traumatic retained hemothorax is a major risk factor for empyema thoracis leading to prolonged hospitalization, entrapped lung and a need for decortication. VATS (Video Assisted Thoracoscopy) for retained hemothorax shortens the duration of chest tube drainage and length of stay. From December 2004 to July 2009, 110 consecutive patients underwent VATS for retained or clotted hemothoraces at the Department of Thoracic Surgery, Jinnah Postgraduate Medical Centre, Karachi.

Experience of thymectomy by median sternotomy in patients with myasthenia gravis.

Objective: To determine the outcome of thymectomy in patients with myasthenia gravis and safety of median sternotomy approach.

Methodology: An observational descriptive study was conducted in the department of thoracic surgery JPMC from February 2005 to January 2009. Twenty-two patients having persistent generalized or ocular myasthenia gravis referred to our department by neurologists and general physicians, partially or not responding to medical treatment with or without thymoma, were included in the study.

Clinical profile and postoperative outcome in patients with simple and complex aspergilloma of lung.

Objective: To compare the clinical presentation and results of pulmonary resection in simple and complex aspergilloma of the lung.

Study Design: Observational study.

Place And Duration Of Study: The Department of Thoracic Surgery, Jinnah Postgraduate Medical Centre, Karachi, from January 2003 to December 2008.

Role of Urgent Thoracotomy in improving the survival of patients with severe chest trauma.

Objective: To determine the frequency of survival in patients with thoracic trauma, undergoing Urgent Thoracotomy (UT).

Study Design: Quasi-experimental study.

Place And Duration Of Study: The study was carried out in the Department of Thoracic Surgery, JPMC, Karachi, from January 2005 to June 2007 (30 months).

Morgagni's hernia.

Morgagni's hernia is an uncommon type of diaphragmatic hernia. These patients usually present in childhood but sometimes later in life. We report a case of 75 years old female who presented with epigastric discomfort and vomiting.
