We report a 67-year-old female patient with ventricular septal perforation after weak blunt chest trauma. She tumbled down on a frozen street. Approximately 1 week later, the patient was aware of shortness of breath on exertion. On admission, holosystolic murmur was detected on chest wall and routine electrocardiogram examination showed ST-T change which suggested myocardial ischemia. Acute myocardial infarction and ventricular septal defect with left-to-right shunt was suspected. The echocardiography and cardiac catheterization revealed the muscular type ventricular septal perforation near the apex with large left-to-right shunt flow (82% shunt ratio). The congestive heart failure was controlled successfully by conservative medical treatment. Surgical repair was scheduled on the 28th day after initial chest trauma because of large left-to-right shunt. A hole of about a diameter of 2 cm with fibrous edge of the muscular septum was closed through a left ventriculotomy using a Dacron patch under cardiopulmonary bypass. Postoperative course was uneventful and the patient was discharged without symptoms of congestive heart failure.

Esophageal Perforation-I: Introduction

Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
The location of esophageal perforation can vary, occurring anywhere along the esophagus.

Esophageal Perforation-II: Clinical Manifestations and Management

Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.

Flail Chest-I

Overview of Flail Chest
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...

Flail Chest-II

Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.

Pneumothorax II: Pathophysiology

Pneumothorax means the presence of air in the pleural space — the thin potential gap between the visceral and parietal pleura. This condition disrupts the normal pressure balance that keeps the lungs inflated, leading to partial or complete collapse of the affected lung.Normal physiologyUnder normal conditions, the pleural space maintains a slightly negative intrapleural pressure, which keeps the lungs expanded against the chest wall. This negative pressure creates a delicate balance between...

Pneumothorax-II

Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.
