PMID: 17240594 MyJurnal

Catheter knotting is a rare complication of bladder catheterisation. Retention of catheter parts resulting in calculus formation is even rarer. We report a case of a vesical calculus formed over a broken and retained supra-pubic catheter which to the best of our knowledge has yet to be reported, along with three other cases of bladder catheter knotting.

Transcatheter closure of multiple muscular ventricular septal defects using Gianturco coils

Latiff HA, Alwi M, Kandhavel G, Samion H, Zambahari R

Ann Thorac Surg, 1999 Oct;68(4):1400-1.
PMID: 10543517

A 10-month-old boy underwent operation to close a large secundum atrial septal defect and multiple muscular ventricular septal defects. Closure of the ventricular septal defects was unsuccessful and led to worsening cardiac failure and inability to wean the patient from mechanical ventilation. Transcatheter closure of the ventricular septal defects using Gianturco coils was undertaken. This technique is an effective alternative for closure of multiple muscular ventricular septal defects in infants and small children.

Fulltext Sengstaken-Blakemore tube to control massive postpartum haemorrhage

Japaraj RP, Raman S

Med J Malaysia, 2003 Oct;58(4):604-7.
PMID: 15190639

Massive postpartum haemorrhage after Cesarean section for placenta previa is a common occurrence. The bleeding is usually from the placental bed at the lower uterine segment. Uterine tamponade has a role in the management of such patients especially when fertility is desired. We describe here a case of massive postpartum haemorrhage, which was managed, with the use of a Sengstaken-Blakemore tube. This allowed us to avoid a hysterectomy for a young primiparous patient.

Fulltext The Amplatzer duct occluder: experience in 209 patients

Bilkis AA, Alwi M, Hasri S, Haifa AL, Geetha K, Rehman MA, et al.

J Am Coll Cardiol, 2001 Jan;37(1):258-61.
PMID: 11153748 DOI: 10.1016/s0735-1097(00)01094-9

Objectives: The aim of the study was to assess the safety and efficacy of the Amplatzer ductal occluder (ADO) in transcatheter occlusion of patent ductus arteriosus (PDA).
Background: Transcatheter closure of small to moderate sized PDAs is an established procedure. The ADO is a self-expandable device with a number of salutary features, notably its retrievability, ease of delivery via small 5F to 7F catheters and a range of sizes suitable even for the larger PDAs.
Methods: Between November 1997 and August 1999, the ADO was successfully implanted in 205 of 209 patients with PDA. The inclusion criteria for this device occlusion method were patients with clinical and echocardiographic features of moderate to large PDA, weighing > or =3.5 kg as well as asymptomatic adolescents and adults with PDA measuring > or =5.0 mm on two-dimensional (2D) echocardiogram. Occlusion was achieved via the antegrade venous approach. Follow-up evaluations were performed with 2D echocardiogram, color-flow mapping and Doppler measurement of the descending aorta and left pulmonary artery velocity at 24 h and 1, 3, 6 and 12 months after implantation.
Results: Two hundred and five patients had successful PDA occlusion using this device. The patients were between two months and 50 years (median 1.9) and weighed between 3.4 kg and 63.2 (median 8.4). Infants made up 26% of the total patients. The PDA measured from 1.8 to 12.5 mm (mean 4.9) at the narrowest diameter. Forty-four percent of patients achieved immediate complete occlusion. On color Doppler the closure rates at 24 h and 1 month after implant were 66% and 97%, respectively. At 6 and 12 months all except one patient attained complete occlusion. Device embolization occurred in three patients; in two this was spontaneous, and in the other it was due to catheter manipulation during postimplant hemodynamic measurement. Mild aortic narrowing was seen in an infant.
Conclusions: Patent ductus arteriosus occlusion using ADO is safe and efficacious. It is particularly useful in symptomatic infants and small children with relatively large PDA. Embolization can be minimized by selection of appropriate sized devices, and caution should be exercised in infants <5 kg.

Modification of Aortic Cannula With an Inlet Chamber to Induce Spiral Flow and Improve Outlet Flow

Darlis N, Osman K, Padzillah MH, Dillon J, Md Khudzari AZ

Artif Organs, 2018 May;42(5):493-499.
PMID: 29280161 DOI: 10.1111/aor.13021

Physiologically, blood ejected from the left ventricle in systole exhibited spiral flow characteristics. This spiral flow has been proven to have several advantages such as lateral reduction of directed forces and thrombus formation, while it also appears to be clinically beneficial in suppressing neurological complications. In order to deliver spiral flow characteristics during cardiopulmonary bypass operation, several modifications have been made on an aortic cannula either at the internal or at the outflow tip; these modifications have proven to yield better hemodynamic performances compared to standard cannula. However, there is no modification done at the inlet part of the aortic cannula for inducing spiral flow so far. This study was carried out by attaching a spiral inducer at the inlet of an aortic cannula. Then, the hemodynamic performances of the new cannula were compared with the standard straight tip end-hole cannula. This is achieved by modeling the cannula and attaching the cannula at a patient-specific aorta model. Numerical approach was utilized to evaluate the hemodynamic performance, and a water jet impact experiment was used to demonstrate the jet force generated by the cannula. The new spiral flow aortic cannula has shown some improvements by reducing approximately 21% of impinging velocity near to the aortic wall, and more than 58% reduction on total force generated as compared to standard cannula.

A new expandable cannula system for endoscopic evacuation of intraparenchymal hemorrhages

Waran V, Vairavan N, Sia SF, Abdullah B

J. Neurosurg., 2009 Dec;111(6):1127-30.
PMID: 19408977 DOI: 10.3171/2009.4.JNS081506

The authors describe a newly developed expandable cannula to enable a more efficient use of an endoscope in removing intraparenchymal spontaneous hypertensive intracerebral hematomas. The cannula is introduced like a conventional brain cannula, using neuronavigation techniques to reach the targeted hematoma accurately, and, once deployed, conventional microsurgical techniques are used under direct endoscopic visualization. This method was used in 6 patients, and, based on the results of intraoperative intracranial pressure monitoring and postoperative CT scanning, the authors were able to achieve good hematoma removal. They found that by using the expandable cannula, efficient endoscopic surgery in the brain parenchyma was possible.

The MitraClip Asia-Pacific registry: Differences in outcomes between functional and degenerative mitral regurgitation

Tay E, Muda N, Yap J, Muller DW, Santoso T, Walters DL, et al.

Catheter Cardiovasc Interv, 2016 Jun;87(7):E275-81.
PMID: 26508564 DOI: 10.1002/ccd.26289

OBJECTIVES: The objective of this study is to describe and compare the use of the MitraClip therapy in mitral regurgitation (MR) patients with degenerative MR (DMR) and functional MR (FMR).
INTRODUCTION: Percutaneous edge-to-edge repair of severe MR using the MitraClip device is approved for use in the USA for high risk DMR while European guidelines include its use in FMR patients as well.
METHODS: The MitraClip in the Asia-Pacific Registry (MARS) is a multicenter retrospective registry, involving eight sites in five Asia-Pacific countries. Clinical and echocardiographic characteristics, procedural outcomes and 1-month outcomes [death and major adverse events (MAE)] were compared between FMR and DMR patients treated with the MitraClip.
RESULTS: A total of 163 patients were included from 2011 to 2014. The acute procedural success rates for FMR (95.5%, n = 84) and DMR (92%, n = 69) were similar (P = 0.515). 45% of FMR had ≥2 clips inserted compared to 60% of those with DMR (P = 0.064).The 30-day mortality rate for FMR and DMR was similar at 4.5% and 6.7% respectively (P = 0.555). The 30-day MAE rate was 9.2% for FMR and 14.7% for DMR (P = 0.281). Both FMR and DMR patients had significant improvements in the severity of MR and NYHA class after 30 days. There was a significantly greater reduction in left ventricular end-diastolic diameter (P = 0.002) and end systolic diameter (P = 0.017) in DMR than in FMR.
CONCLUSIONS: The MitraClip therapy is a safe and efficacious treatment option for both FMR and DMR. Although, there is a significantly greater reduction in LV volumes in DMR, patients in both groups report clinical benefit with improvement in functional class. © 2015 Wiley Periodicals, Inc.

Pain control after thoracotomy. An extrapleural tunnel to provide a continuous bupivacaine infusion for intercostal nerve blockade

Majid AA, Hamzah H

Chest, 1992 Apr;101(4):981-4.
PMID: 1555472

This study was undertaken to determine whether an infusion of local anesthetic (LA) delivered through an extrapleural tunnel could provide satisfactory control of pain in the postthoracotomy period. Twelve patients undergoing thoracotomy were studied. A T-shaped tunnel was created by elevating the parietal pleura at the posteromedial end of the thoracotomy wound. An irrigation catheter was then inserted and an infusion of bupivacaine commenced, initially at 5 mg/kg/24 h and subsequently at 3 mg/kg/24 h. Pain was well controlled in eight patients and satisfactory in four patients. The latter required one dose of opiate analgesia each in the 48-h postoperative period. We conclude that an infusion of bupivacaine into the extrapleural space is an effective means of control of pain after thoracotomy.

Pulmonary atresia with intact septum: the use of Conquest Pro coronary guidewire for perforation of atretic valve and subsequent interventions

Alwi M, Budi RR, Mood MC, Leong MC, Samion H

Cardiol Young, 2013 Apr;23(2):197-202.
PMID: 22640635 DOI: 10.1017/S1047951112000595

Objective: To determine the feasibility and safety of the Conquest Pro wire as an alternative to radiofrequency wire for perforation of atretic pulmonary valve and subsequent balloon dilatation and patent ductus arteriosus stenting in patients with pulmonary atresia with intact ventricular septum.
Background: Radiofrequency valvotomy and balloon dilatation has become the standard of care for pulmonary atresia with intact ventricular septum in many institutions today.
Methods: We report eight consecutive patients in whom we used the Conquest Pro coronary guidewire, a stiff wire normally reserved for revascularisation of coronary lesions with chronic total occlusion, for perforation of atretic pulmonary valve and subsequent balloon dilatation, and stenting of the patent ductus arteriosus.
Results: Perforation of atretic pulmonary valve was successful in seven out of eight cases. Radiofrequency valvotomy was employed after failure of perforation by the Conquest Pro wire in one case where the right ventricular outflow tract was broad based and tapered towards the pulmonary valve, and was heavily trabeculated. Failure of the Conquest Pro wire to perforate the pulmonary valve plate was mainly attributed by the failure to engage the wire at the correct position.
Conclusion: The Conquest Pro wire for perforation and subsequent interventions in the more straightforward cases of pulmonary atresia with intact ventricular septum is effective and safe, simplifying the entire procedure. However, the radiofrequency generator and wires remain essential tools in the paediatric interventional catheter laboratory.

Cardiol Young, 2002 May;12(3):224-8.
PMID: 12365167

This study reviewed the short-term outcome of transcatheter closure of the defects within the oval fossa using an Amplatzer Septal Occluder. From January 1997 to December 2000, 210 patients with defects within the oval fossa underwent successful transcatheter closure. We reviewed a total of 190 patients with left-to-right shunts, assessing the patients for possible complications and the presence of residual shunts using transthoracic echocardiogram at 24 h, 1 month, 3 months and one year. Their median age was 10 years, with a range from 2 to 64 years, and their median weight was 23.9 kg, with a range from 8.9 to 79 kg. In 5 patients, a patent arterial duct was closed, and in 2 pulmonary balloon valvoplasty performed, at the same sitting. The median size of the Amplatzer device used was 20 mm, with a range from 9 to 36 mm. The median times for the procedure and fluoroscopy were 95 min, with a range from 30 to 210 min, and 18.4 min, with a range from 5 to 144 min, respectively. Mean follow-up was 20.8 +/- 12.4 months. Complete occlusion was obtained in 168 of 190 (88%) patients at 24 h, 128 of 133 (96.2%) at 3 months, and 103 of 104 (99%) at one year. Complications occurred in 4 (2.1%) patients. In one, the device became detached, in the second the device embolized into the right ventricular outflow tract, the lower end of the device straddled in the third, and the final patient had significant bleeding from the site of venupuncture. There were no major complications noted on follow-up. We conclude that transcatheter closure of defects within the oval fossa using the Amplatzer Septal Occluder is safe and effective. Long-term follow-up is required, nonetheless, before it is recommended as a standard procedure.

Device closure of patent ductus arteriosus in Marfan patients: safety and effect on the aortic root diameter

Zanjani KS, Wong AR, Sadiq M, Weber HS, Cutler NG

Congenit Heart Dis, 2010 Sep-Oct;5(5):439-43.
PMID: 21087429 DOI: 10.1111/j.1747-0803.2010.00448.x

Objectives: There is little evidence in the medical literature about safety of PDA device closure and its effects on aortic root diameter in Marfan patients. We reported on nine Marfan patients whose ducts were occluded by coil or Amplatzer Duct Occluder.
Patients and interventions: Two patients had aneurismal type E ducts which were closed by a single coil, respectively. The others had conical ducts for which even Amplatzer occluder, stiff, or double coils were used.
Results: No untoward consequence was found during a median follow up period of 18.5 months (range 3 months to 6.33 years). Two patients had small residual shunts. The observed change in the mean ratio of aortic root diameter to its estimated value was statistically insignificant in seven patients who had complete data on their aortic root diameter before PDA closure and during the follow up.
Conclusions: We concluded that PDA device closure in Marfan patients is safe. Risk of residual shunt is higher even after closure of small ducts.

Fulltext Concomitant stenting of the patent ductus arteriosus and radiofrequency valvotomy in pulmonary atresia with intact ventricular septum and intermediate right ventricle: early in-hospital and medium-term outcomes

Alwi M, Choo KK, Radzi NA, Samion H, Pau KK, Hew CC

J. Thorac. Cardiovasc. Surg., 2011 Jun;141(6):1355-61.
PMID: 21227471 DOI: 10.1016/j.jtcvs.2010.08.085

Objectives: Our objective was to determine the feasibility and early to medium-term outcome of stenting the patent ductus arteriosus at the time of radiofrequency valvotomy in the subgroup of patients with pulmonary atresia with intact ventricular septum and intermediate right ventricle.
Background: Stenting of the patent ductus arteriosus and radiofrequency valvotomy have been proposed as the initial intervention for patients with intermediate right ventricle inasmuch as the sustainability for biventricular circulation or 1½-ventricle repair is unclear in the early period.
Methods: Between January 2001 and April 2009, of 143 patients with pulmonary atresia and intact ventricular septum, 37 who had bipartite right ventricle underwent radiofrequency valvotomy and stenting of the patent ductus arteriosus as the initial procedure. The mean tricuspid valve z-score was -3.8 ± 2.2 and the mean tricuspid valve/mitral valve ratio was 0.62 ± 0.16.
Results: Median age was 10 days (3-65 days) and median weight 3.1 kg (2.4-4.9 kg). There was no procedural mortality. Acute stent thrombosis developed in 1 patient and necessitated emergency systemic-pulmonary shunt. There were 2 early in-hospital deaths owing to low cardiac output syndrome. One late death occurred owing to right ventricular failure after the operation. Survival after the initial procedure was 94% at 6 months and 91% at 5 years. At a median follow-up of 4 years (6 months to 8 years), 17 (48%) attained biventricular circulation with or without other interventions and 9 (26%) achieved 1½-ventricle repair. The freedom from reintervention was 80%, 68%, 58%, and 40% at 1, 2, 3, and 4 years, respectively.
Conclusions: Concomitant stenting of the patent ductus arteriosus at the time of radiofrequency valvotomy in patients with pulmonary atresia with intact ventricular septum and intermediate right ventricle is feasible and safe with encouraging medium-term outcome.
