Analysis of charges and complications of permanent pacemaker implantation in the cardiac catheterization laboratory versus the operating room

Advancing global equity in cardiac care as cardiac implantable electronic device reuse comes of age

A nation's health and economic development are inextricably and synergistically connected. Stark differences exist between wealthy and developing nations in the use of cardiac implantable electronic devices (CIEDs). Cardiovascular disease is now the leading cause of death in low- and middle-income countries (LMIC), with a significant burden from rhythm-related diseases. As science, technology, education, and regulatory frameworks have improved, CIED recycling for exportation and reuse in LMIC has become possible and primed for widespread adoption. In our manuscript, we outline the science and regulatory pathways regarding CIED reuse. We propose a pathway to advance this technology that includes creating a task force to establish standards for CIED reuse, leveraging professional organizations in areas of need to foster the professional skills for CIED reuse, collaborating with regulatory agencies to create more efficient regulatory expectations and bring the concept to scale, and establishing a global CIED reuse registry for quality assurance and future science.

[The "Recommendations for the structure of cardiac pacemaker and defibrillator therapy"--what can they achieve?: Implementation of the concept paper for HSM/ICD therapy]

Implantable devices in cardiac electrophysiology have developed from simple machines that prevent bradycardia to complex systems that treat malignant tachyarrhythmias and severe heart failure. Optimal therapeutic utilization of these systems requires profound knowledge of those who treat patients with devices. To account for that, the German Cardiac Society has published "Recommendations for the structure of cardiac pacemaker and defibrillator therapy" to achieve an expertise in 2 levels. These define topics for interdisciplinary education to ensure implantation and follow-up of high quality, as well as infrastructural requirements such as staff and operation rooms. The implementation of these guidelines offers a great opportunity for good quality in device therapy and may enhance the results of the compulsory German quality registry of the respective institution. The established courses of the German Cardiac Society to achieve competence in pacemaker and ICD therapy according to the curricula should be complemented by practical training in accredited centers. Minimum numbers for implantation and follow-up are necessary to ensure a continuously high quality.

Long term complications in single and dual chamber pacing are influenced by surgical experience and patient morbidity

OBJECTIVE

To determine how short and long term complication rates after pacemaker implantation are influenced by patient morbidity, operator experience, and choice of pacing system.

DESIGN

Retrospective analysis of 1884 patients who received VVI (n = 610), VDD (n = 371), or DDD devices (n = 903) between 1990 and 2001. Follow up period was 64 (34) months. The influence of age, sex, coronary artery disease, myocardial infarction, reduced left ventricular (LV) function, right ventricular (RV) dilatation, atrial fibrillation, device type, and operator experience on operation time and complication rate were analysed.

RESULTS

Operation time was prolonged in patients with coronary artery disease, inferior myocardial infarction, reduced LV function, and RV dilatation. Implantation of DDD pacemakers prolonged operation time, particularly among operators with a low or medium level of experience. The overall complication rate was 4.5%. Sixty seven per cent of these complications occurred within the first three months. Complication rate was increased by age, reduced LV function, and RV dilatation. Implantation of DDD systems led to a higher complication rate (6.3%) than implantation of VVI (2.6%) or VDD pacemakers (3.2%). These differences were present only among operators with a low or medium level of experience.

CONCLUSIONS

Operation time and complication rate increased with age, impaired LV function, and RV dilatation. Complication rates were higher with DDD than with VVI or VDD implantation and were excessive among inexperienced but not experienced operators.

Titanium miniplates or stainless steel wire for cranial fixation: a prospective randomized comparison

OBJECT

The authors designed a study to compare low-profile titanium miniplate fixation to that in which stainless steel wire is used.

METHODS

Before undergoing craniotomy, 40 patients gave informed consent and were randomized to receive either wire or miniplate fixation. After dural closure, bone flap fixation was timed. The bone flap was measured for inward or outward offset and mobility to manual pressure on its margin. Three months postoperatively the bone flap margins were graded for appearance or palpation of an offset and for the presence of burr hole depressions. Twenty-four patients were randomized to receive miniplate fixation and 16 to receive stainless steel wire fixation. The time required for wire fixation was approximately 40% longer than that for miniplates (11.8 +/- 5.1 minutes compared with 8.3 +/- 5 minutes, p = 0.02). The offset of bone flaps after wire fixation was significantly greater than that with miniplates (1.6 +/- 1 mm compared with 0.3 +/- 0.6 mm, p < 0.001), as was the mobility of the bone flap on digital pressure (1.2 +/- 0.9 mm compared with 0.2 +/- 0.5 mm, p < 0.001). At the 3-month follow-up review, two of 12 patients had suboptimal results after wire fixation, whereas none of 14 patients had suboptimal results after miniplate fixation. When dichotomized for excellent or less-than-excellent postoperative results, the data were significantly better for patients who underwent miniplate fixation (p < 0.05).

CONCLUSIONS

Titanium miniplate cranial fixation provides more accurate and rigid reapproximation of the bone edges, with results that are significantly better on close inspection or palpation. The additional cost of miniplate fixation may thus be justified in many cases.
