Pericardial effusion is caused by many underlying medical and surgical conditions. Among the causes of effusion as cited by the European Society of Cardiology are of the following in accordance to incidence; idiopathic, infectious, immune-inflammatory, neoplastic diseases, radiation induced, early post-cardiac surgery, device and procedure related, blunt and penetrating trauma1. These underlying conditions cause massive effusion that impairs the functional ability of the human heart. In most cases, patients presenting with cardiac tamponade needs immediate surgical intervention. Among the drainage procedures, Subxiphoid pericardiostomy is one of the most common, easy, and high risk procedure subjected to a human pericardium.
The risk for subxiphoid pericardiostomy carries equivalent morbidity and mortality. The vast majority of the studies published in literature suggest that the subxiphoid pericardiostomy is an expeditious, easy, and inexpensive procedure, which can be applied to a wide spectrum of pericardial effusions. The technique provides accurate diagnosis and effective, durable treatment with an operation-related mortality ranging between 0% and 5 % and a recurrence rate 0 to 9.1%2
This study will determine the etiology and outcome of patients with pericardial effusion who underwent subxiphoid pericardiostomy. Furthermore, the study will also enumerate the different demographic and clinical characteristic of patients undergoing this procedure.
2. What has been known about the topic?
Subxiphoid pericardiostomy for the treatment of pericardial effusion has been elaborated in many articles worldwide3. The cause of pericardial effusion and the type of drainage procedure is often related to underlying conditions. This procedure is both diagnostic and therapeutic in nature.
Myriad of causes has been identified for pericardial effusion. In one case series study showed that out of 348 participants, uremia is the most common cause of pericardial effusion compared to what was identified by the european society of cardiology2.
In another european study, pericardial effusions and/or tamponade are reviewed and compared based on 12 years of surgical experience. They have concluded that choosing a method for pericardial decompression, it’s the disease etiology and patient characteristics must be considered as well as the experience of the surgeon.
Echocardiography is identified as the gold standard for the diagnosis of pericardial effusion. Thus, when the diastolic echo-free space between the left ventricular posterior wall and pericardium was 10 mm it was classified as mild, 10–20 mm was classified as moderate, and 20 mm was classified as severe pericardial effusion3.
Diagnosis of cardiac tamponade is achieved by clinical and imaging criteria. The presence of classic traid tamponade—distended neck veins, hypotension and muffled heart sound with clear lungs all together or with echocardiographic findings was accepted as cardiac tamponade. Furthermore, there were no mention in literatures the use of conventional ultrasound for the diagnosis of pericardial effusion. However, In an asian study, conventional ultrasound was used in traumatic pericardial effusion and distance between the pericardium and the myocardium was the basis for indicating a free space for pericardisotomy
Echocardiographic criteria of tamponade were examined by two dimensional and Doppler echocardiography. Two dimensional echocardiographic criteria of tamponade were early diastolic collapse of the right ventricle, late diastolic collapse of the right or left atrium, and plethora of the inferior vena cava with pericardial effusion4. Doppler echocardiographic criteria of tamponade were major increases of tricuspid E flow and major decreases of mitral E flow during inspiration compared with apnoea (with the reverse in expiration).
There are many clinical presentation of pericardial effusion. Pericardial disease is a common entity, pericardial tamponade is the usual presenting feature. It occurs in about 25% of all cases of pericardial effusion. Symptomatic pericardial effusions occur as a result of multiple disease processes and can be treated with many different procedures. Pericardiocentesis, transcutaneous pericardioscopic, pleura-pericardial window, and subxiphoid pericardial drainage4. Each of these surgical treatments can be effective, depending on clinical factors and the history of the patient. For this reason, the optimal procedure for treatment of these effusions remains controversial, and none of them is optimal for all patients and circumstances.
Pericardiocentesis is life saving in cardiac tamponade and indicated in effusions4. The most serious complications of pericardiocentesis are laceration and perforation of the myocardium and the coronary vessels. Safety was improved with echocardiographic or fluoroscopic guidance.
The ideal procedure should be easy to perform, result in minimal morbidity and mortality, ensure complete and permanent drainage, have infrequent recurrences, and provide sufficient histological, cytological, and microbiologic specimens for diagnosis of the cause of the effusion.
The potential advantages of subxiphoid pericardiostomy are direct visualisation and exploration of the pericardium and pericardial cavity, the ability to probe the pericardial cavity to allow for complete drainage, biopsy of the pericardium for pathological analysis, and placement of a larger calibre tube for better drainage. Video assisted transthoracic pericardial drainage has been touted as effective for preventing effusion recurrence through a large pericardial resection with the creation of a ‘‘pericardial window’’. It requires, however, general anaesthesia and single lung ventilation, procedures that are difficult in critically ill patients. In a series of 368 patients with pericardial effusion, subxiphoid pericardiostomy was performed under local anaesthesia with sedation (n = 346, 94%) or general anaesthesia (n = 22, 6%) during the 13 years between 1990 and 2003. General anaesthesia was preferred for children. Pericardiocentesis was performed as a temporary procedure on 15 of our 368 patients4.
Different methods and approaches are described, which are summarized below:
Needle aspiration. This method has been used for decades the advantages and disadvantages have been well described in previous reports.
2. Small plastic tube drainage. This method has a disadvantage, the small tube becomes plugged up and the pericardial fluid is left behind because of loculations.
3. Anterior thoracotomy with or without video-assisted thoracic surgery. This method at times necessitates a chest tube.
4. Classic subxiphoid pericardial window. The safety of this method depends greatly on whether the pericardium contains fair amounts of fluid and/or is grossly adherent to the heart or occupied by metastatic tumor. Cases with bleeding into the pericardium due to imbalance of anticoagulants or to myocardial infarctions are problematic, and percutaneous tube pericardiostomy decompression should be considered only if the preoperative echocardiogram indicates significant pericardial effusion with fluid volume greater than 100 to 150 mL without loculation.
What is not yet known about the topic?
There has been no local statistical data yet in Mindanao regarding the clinical profiles of pericardial effusion who underwent subxiphoid pericardiostomy. This will determine the etiology of pericardial effusion who has undergone subxiphoid pericardiostomy.
What is the significance of the study
The study focused on the descriptive statistics. This is a pilot study for patient with pericardial effusion who underwent subxiphoid pericardiostomy in our locality. The demographic, clinical and etiology of pericardial effusion and the indications for pericardiostomy will be enumerated in this study.
What will your study do?
